Bispectral electroencephalographic analysis of patients undergoing procedural sedation in the emergency department.

OBJECTIVE: To determine whether there is a correlation between the level of sedation achieved during procedural sedation (PS) in the emergency department as determined by bispectral electroencephalographic (EEG) analysis (BIS) and the rate of respiratory depression (RD), the patient's perception of pain, recall of the procedure, and satisfaction. METHODS: This was a prospective observational study conducted in an urban county hospital of adult patients undergoing PS using propofol, methohexital, etomidate, and the combination of fentanyl and midazolam. Consenting patients were monitored by vital signs, pulse oximetry, nasal-sample end-tidal carbon dioxide (ETCO(2)), and BIS monitors during PS. Respiratory depression (RD) was defined as an oxygen saturation <90%, a change from baseline ETCO(2) of >10 mm Hg, or an absent ETCO(2) waveform at any time during the procedure. After the procedure, patients were asked to complete three 100-mm visual analog scales (VASs) concerning their perception of pain, recall of the procedure, and satisfaction with the procedure. Patients were divided into four groups based on the lowest BIS score recorded during the procedure, group 1, >85; group 2, 70-85; group 3, 60-69; group 4, <60. Rates of RD and VAS outcomes were compared between groups using chi-square statistics. RESULTS: One hundred eight patients were enrolled in the study. No serious adverse events were noted. RD was seen in three of 14 (21.4%) of the patients in group 1, seven of 34 (20.6%) in group 2, 16 of 26 (61.5%) in group 3, and 18 of 34 (52.9%) in group 4. The rate of RD in patients in group 2 was not significantly different from that in group 1 (p = 0.46). The rate of RD in group 2 was significantly lower than that in groups 3 (p = 0.0003) and 4 (p = 0.006). For the VAS data, when group 1 was compared with the combined groups 2, 3, and 4, it had significantly higher rates of pain (p = 0.003) and recall (p = 0.001), and a dissatisfaction rate (p = 0.085) that approached significance. When groups 2, 3, and 4 were compared with chi-square test, there was not a significant difference in pain (p = 0.151), recall (p = 0.27), or satisfaction (p = 0.25). CONCLUSIONS: Patients with a lowest recorded BIS score between 70 and 85 had the same VAS outcomes as more deeply sedated patients and the same rate of RD as less deeply sedated patients. This range of scores represented the optimally sedated patients in this study.

Novel monitoring techniques for use with procedural sedation.

PURPOSE OF REVIEW: A variety of pharmacologic agents used for procedural sedation in children to reduce pain and anxiety may produce respiratory depression and hypotension. Although standard monitoring guidelines include oxygen saturation, this measurement is limited as a guide to respiratory function. This review discusses two new monitoring techniques recently introduced to the pediatric emergency department that facilitate procedural sedation and reduce potential adverse effects of the medications administered. RECENT FINDINGS: Capnography via an end-tidal carbon dioxide monitor measures carbon dioxide concentrations during ventilation. This measurement is independent of oxygen saturation and thereby aids the clinician in identifying hypoventilation and apnea in the sedated patient at an earlier stage than conventional monitoring. The bispectral index monitor objectively measures the depth of sedation by analyzing electroencephalogram signals from a cutaneous probe. This tool enables the physician to titrate sedative medications to a desired effect and thereby reduce the risks associated with oversedation. SUMMARY: Studies have illustrated the use of both devices as adjuncts to current standard monitoring of children in the outpatient setting. These modalities will facilitate the efficacy of procedural sedation in children and improve safety by enabling early recognition of hypoventilation and by reducing the risk of oversedation in children undergoing procedural sedation.

Procedural sedation in the community emergency department: initial results of the ProSCED registry.

OBJECTIVES: Procedural sedation and analgesia (PSA) has been well profiled in experimental studies in university emergency departments. Extrapolation of these practices into the community hospital setting is not well established. This report describes community hospital practices and outcomes in a multicenter PSA registry. METHODS: The Procedural Sedation in the Community Emergency Department (ProSCED) registry is a prospective observational database composed of consecutive emergency physician-directed procedural sedation cases in community hospitals. Registered procedures described by 15 categorical data fields are collected at the time of the patient encounter and entered into a secure Internet-housed database. RESULTS: A total of 1,028 procedural sedations were performed on 980 patients at 14 study sites. The most common specified procedures performed included shoulder relocation (392), hip relocation (102), elbow relocation (70), upper extremity fracture care (69), lower extremity fracture care (66), and facial laceration repair (67). Complications of any description occurred in 42 cases (4.1%), with no patient's disposition changed secondary to a complication. Patients' ages ranged from 1 month to 95 years, with a median age of 31 years. Of procedures attempted, 982 (95.5%) were successfully completed, 21 cases (2.0%) were adequately sedated but unable to have their procedure completed, and 21 cases (2.0%) were believed to be inadequately sedated. Medication use included midazolam in 423 cases (41.1%), propofol in 253 (24.6%), fentanyl in 253 (24.6%), etomidate in 241 (23.4%), and ketamine in 145 (14.1%), as well as several others. Cases using either ketamine or propofol exhibited the fewest complications, while those using fentanyl, hydromorphone, or midazolam demonstrated the highest complication rates. CONCLUSIONS: Community emergency physicians deliver safe and effective PSA over a wide variety of ages and procedures while using a broad selection of agents.

Etomidate for procedural sedation in the emergency department.

OBJECTIVE: To review the current efficacy and safety evidence for the use of etomidate for procedural sedation in the emergency department (ED). DATA SOURCES: MEDLINE (1966-December 2003), EMBASE (1980-December 2003), PubMED (1966-December 2003), and Cochrane Database of Systemic Reviews (up to December 2003) were searched for full-text reports published in English on the use of etomidate in humans. Search terms included etomidate, procedural sedation, conscious sedation, relocation, dislocation, abscess incision, abscess drainage, and cardioversion. STUDY SELECTION AND DATA EXTRACTION: Prospective and retrospective studies evaluating efficacy or safety endpoints using etomidate for procedural sedation in the ED were included. All studies were evaluated independently by both authors. For clinical outcomes (efficacy, safety), the definitions specified by each study were used. DATA SYNTHESIS: Three observational studies and 5 prospective, randomized controlled trials were included in this review. Onset of action and time to recovery following etomidate were rapid and found to be comparable to that of propofol and thiopental but significantly faster than that of midazolam. The dose of etomidate for procedural sedation ranged from 0.15 to 0.22 mg/kg. No significant hemodynamic effects were observed; however, respiratory depression resulting in oxygen desaturation to <90% or apnea appears to occur in approximately 10% of patients undergoing procedural sedation with etomidate with or without analgesia. The most prominent adverse effect reported with etomidate was myoclonus, occurring in 20-45% of patients. CONCLUSIONS: Etomidate is an appropriate and valuable agent for performing procedural sedation in the ED. The rapid onset and recovery time and relative lack of significant hemodynamic and respiratory effects may facilitate optimal and safe conditions for procedural sedation in the ED.

Preprocedural fasting state and adverse events in children undergoing procedural sedation and analgesia in a pediatric emergency department.

STUDY OBJECTIVE: Assessment of preprocedural fasting is considered essential in minimizing the risks of procedural sedation and analgesia. Established fasting guidelines are difficult to follow in the emergency department (ED). We characterize the fasting status of patients receiving procedural sedation and analgesia in a pediatric ED and assess the relationship between fasting status and adverse events. METHODS: A prospective case series was conducted in a children's hospital ED during an 11-month period. All consecutive patients requiring procedural sedation and analgesia were included. Preprocedural fasting state and adverse events were recorded. The percentage of patients undergoing procedural sedation and analgesia who did not meet fasting guidelines was determined. Adverse events were analyzed in relation to fasting status. RESULTS: One thousand fourteen patients underwent procedural sedation and analgesia, and data on fasting status were available for 905 (89%) patients. Of these 905 patients, 509 (56%; 95% confidence interval [CI] 53% to 60%) did not meet fasting guidelines. Seventy-seven adverse events occurred in 68 (6.7%; 95% CI 5.2% to 8.4%) of the 1,014 patients. All adverse events were minor and successfully treated. Adverse events occurred in 32 (8.1%; 95% CI 5.6% to 11.2%) of 396 patients who met and 35 (6.9%; 95% CI 4.8% to 9.4%) of 509 patients who did not meet fasting guidelines. There was no significant difference in median fasting duration between patients with and without adverse events and between patients with and without emesis. Emesis occurred in 15 (1.5%) patients. There were no episodes of aspiration (1-sided 97.5% CI 0% to 0.4%). CONCLUSION: Fifty-six percent of children undergoing ED procedural sedation and analgesia were not fasted in accordance with established guidelines. There was no association between preprocedural fasting state and adverse events.

A prospective evaluation of "ketofol" (ketamine/propofol combination) for procedural sedation and analgesia in the emergency department.

STUDY OBJECTIVE: We evaluate the effectiveness and consider the safety of intravenous ketamine/propofol combination ("ketofol") in the same syringe for procedural sedation and analgesia in the emergency department (ED). METHODS: A prospective case series of consecutive ketofol procedural sedation and analgesia events in the ED of a trauma-receiving community teaching hospital from July 2005 to February 2006 was studied. Patients of all ages, with any comorbid conditions, were included. Ketofol (1:1 mixture of ketamine 10 mg/mL and propofol 10 mg/mL) was administered intravenously at the discretion of the treating physician by using titrated aliquots. The presence or absence of adverse events was documented, as were procedural success, recovery time, and physician, nurse, and patient satisfaction. Physiologic data were recorded with established hospital procedural sedation and analgesia guidelines. RESULTS: One hundred fourteen procedural sedation and analgesia events using ketofol were performed for primarily orthopedic procedures. The median dose of medication administered was ketamine at 0.75 mg/kg and propofol at 0.75 mg/kg (range 0.2 to 2.05 mg/kg each of propofol and ketamine; interquartile range [IQR] 0.6 to 1.0 mg/kg). Procedures were successfully performed without adjunctive sedatives in 110 (96.5%) patients. Three patients (2.6%; 95% confidence interval [CI] 0.6% to 7.5%) had transient hypoxia; of these, 1 (0.9%; 95% CI 0.02% to 4.8%) required bag-valve-mask ventilation. Four patients (3.5%; 95% CI 1.0% to 8.7%) required repositioning for airway malalignment, 4 patients (3.5%; 95% CI 1.0% to 8.7%) required adjunctive medication for sedation, and 3 patients (2.6%; 95% CI 0.6% to 7.5%) had mild unpleasant emergence, of whom 1 (0.9%; 95% CI 0.02% to 4.8%) received midazolam. No patient had hypotension or vomiting or received endotracheal intubation. Median recovery time was 15 minutes (range 5 to 45 minutes; IQR 12 to 19 minutes). Median physician, nurse, and patient satisfaction scores were 10 on a 1-to-10 scale. CONCLUSION: Ketofol procedural sedation and analgesia is effective and appears to be safe for painful procedures in the ED. Few adverse events occurred and were either self-limited or responded to minimal interventions. Recoveries were rapid, and staff and patients were highly satisfied.

Propofol versus midazolam/ketamine for procedural sedation in pediatric oncology.

Different pharmacologic agents have been used for sedation in children undergoing invasive procedures. The authors prospectively compared the efficacy, the occurrence of adverse effects, cardiovascular parameters, oxygen saturation and induction, and recovery time in propofol with or without morphine versus midazolam/ketamine sedation for procedural sedation in children with malignancies and hematologic disorders. Fifty children received either propofol with or without morphine or ketamine/midazolam sedation for invasive procedures. Intravenous sedation consisted of 0.1 mg midazolam/kg and 1.0 mg ketamine/kg or 2 mg propofol/kg with or without 0.1 mg morphine/kg. Incremental dosages of ketamine or propofol were given, if necessary, to achieve or to maintain adequate sedation levels. Systolic and diastolic blood pressure, heart rate, oxygen saturation, time to induce sedation, recovery time, and adverse effects were recorded. All invasive procedures were successfully completed, with satisfactory sedation levels in all 25 patients in the propofol group and 23 of the 25 patients in the ketamine group. In 14 of the 25 procedures in the propofol group and 4 of the 25 procedures in the ketamine group, sedation was associated with side effects, the most common being oxygen desaturation. There was a significant increase in diastolic blood pressure after ketamine medication and a significant decrease in systolic and diastolic blood pressure and heart rate in the propofol group. Induction and recovery times in the propofol group were significantly shorter. Both regimens for procedural sedation are efficacious in achieving satisfactory sedation levels for invasive procedures. Propofol offers a quicker onset of sedation and a faster, smoother recovery but is associated with a higher rate of side effects. Considering the substantial rate of adverse effects, these procedural sedations should be performed only by physicians trained in advanced airway management and life support.

Intravenous etomidate for procedural sedation in emergency department patients.

OBJECTIVE: To determine the safety and effectiveness of intravenous (IV) etomidate for the sedation of patients undergoing painful procedures in the emergency department (ED). METHODS: A two-part feasibility study for ED patients receiving IV etomidate for painful ED procedures was undertaken. In the initial phase, a retrospective series of patients receiving etomidate for ED procedural sedation was considered. This phase served as the basis for a descriptive, prospective feasibility study of consecutive ED patients. During the second phase, patients were evaluated for complications related to IV etomidate sedation or the procedure performed. Immediately following the procedure, the physician was asked to complete a data collection sheet documenting the patient's etomidate dose, the number of doses required to complete the procedure, the analgesic used, the complications of the procedure, and the patient's procedural recall. RESULTS: Intravenous etomidate was administered to nine patients during the initial study phase and 51 during the prospective, descriptive phase. Indications for sedation included dislocation reduction (25), cardioversion (7), fracture reduction (20), abscess incision and drainage (4), foreign body removal (3), and chest thoracostomy (1). Physicians used 0.1-mg/kg IV bolus etomidate. A mean of 1.6 doses of etomidate was used to complete procedures (range 1-3 doses). Of the 60 patients in both study groups, 59 (98%) achieved adequate sedation by physician's assessment. Procedural success was documented for 56 patients (93%). There were 12 complications reported: oxygen desaturation below 90% (5), myoclonus (4), vomiting (1), pain with injection (1), and a brief bradycardic episode (1). No patient required assistance with ventilation or endotracheal intubation. CONCLUSIONS: Intravenous etomidate can be administered safely and effectively to provide appropriate conscious sedation for short, painful ED procedures.

Pediatric procedural sedation and analgesia.

Children often present with painful conditions that require painful interventions. Procedural sedation and analgesia refers to the pharmacologic technique of managing a child's pain and anxiety. Procedural sedation is a safe, effective, and humane way to facilitate appropriate medical care. It is important to distinguish the goals for the procedural sedation, pain relief or anxiolysis or both. Different medications and combinations of medications can be used to achieve the desired effect. It is also important to keep in mind the possible adverse reactions and side effects associated with each medication when choosing the sedation cocktail.

Etomidate and midazolam for procedural sedation: prospective, randomized trial.

OBJECTIVE: To evaluate whether there is a difference in the time of sedation and time to patient disposition in patients undergoing procedural sedation with etomidate and midazolam. METHODS: Prospective, randomized, double-blind trial comparing etomidate (0.10 mg/kg) and midazolam (0.035 mg/kg) for patients requiring procedural sedation for reduction of joint dislocations or long bone fractures. RESULTS: Forty-five patients were enrolled (24 randomized to etomidate, 21 to midazolam). Groups were similar in demographics and analgesic dosing. Mean time of sedation for etomidate was 15 minutes (SD, 10.97) and for midazolam was 32 minutes (SD, 16.13) (P<.001). Mean time to disposition for etomidate was 121 minutes (SD, 73.28) and for midazolam was 111 minutes (SD, 96.36) (P=.700). The mean quality of sedation for etomidate was 7.91 (SD, 1.53) and for midazolam was 7.48 (SD, 2.89) (P=.570). CONCLUSIONS: The use of etomidate compared with midazolam for procedural sedation provides a significant reduction in recovery time, without a reduction in time to patient disposition, while providing equal sedation quality.

Abdominoplasty with procedural sedation and analgesia.

The ability to perform abdominal cosmetic surgery in the ambulatory setting provides a more comfortable environment for the patient, ease of scheduling for the physician, and decreased costs. Avoiding the use of general anesthesia allows for quicker recovery, shorter length of hospital stay, and decreased rate of postoperative complications. The authors report 106 consecutive abdominoplasties, including fascial plication when indicated, using local anesthesia, with procedural sedation and analgesia. All procedures were performed with an anesthesiologist providing intraoperative monitoring of the patients. Their protocol uses procedural sedation and analgesia, which results in a depressed level of consciousness, but allows the patient to maintain airway control independently and continuously. The results of this approach were measured in terms of procedure time, length of hospital stay, rate of complications, total recovery time, and the level of patient satisfaction. Between January 1996 and January 1999, 106 patients underwent abdominoplasty (performed by one of the authors) under local anesthesia with procedural sedation and analgesia. All patients had an American Society of Anesthesiologists status of 1 to 3, and underwent a full abdominoplasty, including fascial plication. In 26% of the patients, allied procedures were also performed, most commonly liposuction or augmentation mammaplasty. The mean age in this series was 45 years, and all patients were available for follow-up at least 1 year after surgery. The mean operative time was 135 minutes, recovery room time was 68 minutes, and all patients were ambulatory. There were no surgical complications, including flap loss or wound dehiscence, and no complications related to anesthesia (cardiac, deep vein thrombosis, fat emboli, pulmonary embolism, etc.). Because paralytic agents were not used, none of the patients required catheterization postoperatively. Patients were generally pleased with the results of surgery. Although the extent of the surgery remains the same, this approach provided patients with an easier postoperative experience. In summary, abdominoplasty, including full fascial plication of the rectus and external oblique aponeurosis, can be performed safely and comfortably under local anesthesia with procedural sedation and analgesia. Patients are comfortable, recover quickly, and are very satisfied with their surgical result and overall experience.

Aspiration pneumonitis requiring intubation after procedural sedation and analgesia: a case report.

Emergency department (ED) procedural sedation and analgesia is widely and routinely performed; serious complications are rare. We describe the first reported case of aspiration during procedural sedation in the ED. Although our patient required endotracheal intubation and critical care admission, there was no adverse long-term outcome. Given that there were no apparent predisposing factors, we believe it is crucial for emergency physicians to routinely anticipate the possibility of such a complication during each sedation event.

A combination of midazolam and ketamine for procedural sedation and analgesia in adult emergency department patients.

OBJECTIVE: To describe the clinical characteristics of a combination of midazolam and ketamine for procedural sedation and analgesia in adult emergency department (ED) patients. METHODS: This was a prospective, observational trial, conducted in the ED of an urban level II trauma center. Patients > or = 18 years of age requiring procedural sedation and analgesia were eligible, and enrolled patients received 0.07 mg/kg of intravenous midazolam followed by 2 mg/kg of intravenous ketamine. Vital signs were recorded at regular intervals. The adequacy of sedation, adverse effects, patient satisfaction, and time to reach discharge alertness were determined. Descriptive statistics were calculated using statistical analysis software. RESULTS: Seventy-seven patients were enrolled. Three were excluded due to protocol violations, three due to lack of documentation, and one due to subcutaneous infiltration of ketamine, leaving 70 patients for analysis. The average age was 31 years, and 41 (59%) were female. Indications for procedural sedation and analgesia included abscess incision and drainage (66%), fracture/joint reduction (26%), and other (8%). The mean dose of midazolam was 5.6 +/- 1.4 mg and the mean dose of ketamine was 159 +/- 42 mg. The mean time to achieve discharge criteria was 64 +/- 24 minutes. Five patients experienced mild emergence reactions, but there were no episodes of hallucinations, delirium, or other serious emergence reactions. Eighteen (25%) patients recalled dreaming while sedated; twelve (17%) were described as pleasant, two (3%) unpleasant, three (4%) both pleasant and unpleasant, and one (1%) neither pleasant nor unpleasant. There were four (6%) cases of respiratory compromise, two (3%) episodes of emesis, and one (1%) case of myoclonia. All of these were transient and did not result in a change in the patient's disposition. Only one (1%) patient indicated that she was not satisfied with the sedation regimen. CONCLUSIONS: The combination of midazolam and ketamine provides effective procedural sedation and analgesia in adult ED patients, and appears to be safe.

The utility of the bispectral index in procedural sedation with propofol in the emergency department.

UNLABELLED: The bispectral index (BIS) may be a useful monitor to predict the level of awareness in patients undergoing procedural sedation in the emergency department (ED). OBJECTIVES: The authors hypothesized that using the BIS during procedural sedation in the ED would increase the recognition of adequately sedated patients, thus reducing oversedation and the corresponding increased rate of respiratory depression (RD). As a result, the occurrence of RD would be reduced. METHODS: This was a prospective randomized study of ED procedural sedation with propofol. Sedations were randomized to have the treating physician either blinded or not blinded to information from the BIS monitor. Vital signs, pulse oximetry, end-tidal carbon dioxide (ETCO(2)), propofol dosage, and the BIS score were recorded. RD was defined as a change in ETCO(2) greater than 10 mm Hg, an oxygen saturation of less than 90% at any time, or an absent ETCO(2) waveform. The RD rates were compared with chi-square tests. RESULTS: One hundred five patients were enrolled in the study; five were excluded due to study protocol violations. No serious adverse events were reported. RD was seen in 29 of 100 (29%) patients; 18 of 48 in the BIS-blinded group and 11 of 52 in the BIS-unblinded group had RD (p = 0.06). For patients requiring only a single dose of propofol, three of 15 in the BIS-blinded group and four of 18 in the BIS-unblinded group met the criteria for RD (p = 0.87). For patients requiring multiple doses of propofol, 15 of 33 patients in the BIS-blinded group and seven of 34 patients in the BIS-unblinded group met criteria for RD (p = 0.02). The mean BIS nadir for BIS-blinded patients was 60.9 (95% CI = 56.9 to 65.0) and that for BIS-unblinded patients was 63.2 (95% CI = 57.7 to 65.3) (p = 0.22). CONCLUSIONS: There was a lower rate of RD when physicians had access to the BIS during procedural sedations. This difference was greater in sedations requiring multiple doses of propofol. There was no difference in the rate of RD when only a single dose was given.

Etomidate for procedural sedation in emergency medicine.

STUDY OBJECTIVE: We describe and analyze the effectiveness and safety of etomidate for procedural sedation and evaluate the patient's perspective on effectiveness, side effects, and satisfaction. METHODS: We conducted an observational retrospective study of all patients who received etomidate for procedural sedation over 2 years in 3 affiliated suburban emergency departments of a large group-model health maintenance organization. Data were abstracted from the ED records. Additionally, a patient questionnaire was prospectively administered by telephone. RESULTS: Etomidate was used for sedation in 134 patients between 6 and 93 years of age during 150 procedures. The mean cumulative dose was 0.20 mg/kg. Adjunctive medication was used in 36 (23%) procedures. Moderate sedation with verbal arousability was induced in 48 (32%) patients, and deep sedation with verbal unresponsiveness was induced in 102 (68%) patients. Full recovery to the preprocedural level of alertness was achieved within 30 minutes in 142 (95%) of procedures. Mean changes in systolic blood pressure, pulse rate, and oxygen saturation were clinically insignificant. There were 7 (4.7%; 95% confidence interval [CI] 1.9% to 9.4%) adverse events, including 5 (3.3%; 95% CI 1.1% to 7.6%) cases of oxygen desaturation below 94% in older patients (>55 years of age) who received slightly higher mean doses of etomidate (0.23 mg/kg). Four of these patients received brief assisted bag-valve-mask ventilation and recovered uneventfully; none required endotracheal intubation. The questionnaire was completed by 120 (90%) of 134 patients and involved 136 procedures. During 127 (93%) of these, etomidate was believed to be extremely effective in causing sleep, and for 127 (93%) it induced complete procedural amnesia. Only 5 (4%) patients experienced nausea or vomiting. Regarding willingness to receive etomidate for their next procedure, the patients' responses were favorable: extremely, 95%; moderately, 2%; slightly, 3%; and not at all, 1%. CONCLUSION: Etomidate is a useful agent for carefully conducted procedural sedation because it provides effective, brief, deep sedation with little hemodynamic compromise. Its safety may be jeopardized by the occurrence of respiratory depression in older patients receiving higher doses. Patients report a high degree of satisfaction with etomidate.

Preprocedural fasting and adverse events in procedural sedation and analgesia in a pediatric emergency department: are they related?

STUDY OBJECTIVE: Fasting time before procedural sedation and analgesia in a pediatric emergency department (ED) was recently reported to have no association with the incidence of adverse events. This study further investigates preprocedural fasting and adverse events. METHODS: Data were analyzed from a prospectively generated database comprising consecutive sedation events from June 1996 to March 2003. Comparisons were made on the incidence of adverse events according to length of preprocedural fasting time. RESULTS: Two thousand four hundred ninety-seven patients received procedural sedation and analgesia. Four hundred twelve patients were excluded for receiving oral or intranasal drugs (n=95) or for receiving sedation for bronchoscopy by nonemergency physicians (n=317). A total of 2,085 patients received parenteral sedation by emergency physicians. Age range was 19 days to 32.1 years (median age 6.7 years); 59.9% were male patients. Adverse events observed included desaturations (169 [8.1%]), vomiting (156 [7.5%]), apnea (16 [0.8%]), and laryngospasm (3 [0.1%]). Fasting time was documented in 1,555 (74.6%) patients. Median fasting time before sedation was 5.1 hours (range 5 minutes to 32.5 hours). When the incidence of adverse events was compared among patients according to fasting time in hours (0 to 2, 2 to 4, 4 to 6, 6 to 8, >8, and not documented), no significant difference was found. No patients experienced clinically apparent aspiration. CONCLUSION: No association was found between preprocedural fasting and the incidence of adverse events occurring with procedural sedation and analgesia.

Procedural sedation use in the ED: management of pediatric ear and nose foreign bodies.

This is the first report of which we are aware that describes the use of procedural sedation for the emergency department management of ear and nose foreign bodies in children < 18 years of age. During a 5.5-year period, we identified 312 cases of children with a foreign body in a single orifice (174 ear, 138 nose). Procedural sedation was performed in 23% of cases (43 ear, 28 nose) and ketamine was used most commonly (92%). Emergency physicians had a high rate of success in removing foreign bodies (84% ear, 95% nose) and a low complication rate. Procedural sedation had a positive effect on the success rate as more than half of the sedation cases had undergone failed attempts without sedation by the same physician. Emergency physicians should have familiarity with this indication for procedural sedation.

Randomized clinical trial of etomidate versus propofol for procedural sedation in the emergency department.

STUDY OBJECTIVE: We compare the efficacy, adverse events, and recovery duration of etomidate and propofol for use in procedural sedation in the emergency department (ED). METHODS: This was a randomized nonblinded prospective trial of adult patients undergoing procedural sedation for painful procedures in the ED. Patients received either propofol or etomidate. Doses, vital signs, nasal end-tidal CO2 (ETCO2), pulse oximetry, and bispectral electroencephalogram analysis scores were recorded. Subclinical respiratory depression was defined as a change in ETCO2 greater than 10 mm Hg, an oxygen saturation of less than 92% at any time, or an absent ETCO2 waveform at any time. Clinical events related to respiratory depression, including an increase in supplemental oxygen, the use of a bag-valve-mask apparatus, airway repositioning, or stimulation to induce breathing, were noted during the procedure. After the procedure, patients completed visual analog scales about perceived pain during the procedure and recall of the procedure. RESULTS: Two hundred twenty patients were enrolled; 214 underwent sedation and were analyzed. One hundred five patients received etomidate and 109 received propofol. No clinically significant complications were noted. Subclinical respiratory depression was observed in 36 of 105 (34.3%) patients in the etomidate group and 46 of 109 (42.2%) in the propofol group (difference -7.9%; 95% confidence interval [CI] -20.9% to 5.1%). Myoclonus was noted in 21 of 105 (20.0%) patients in the etomidate group and 2 of 109 (1.8%) in the propofol group (difference 18.2%; 95% CI 10.1% to 26.2%). The mean difference between baseline systolic blood pressure and the nadir was 3.8% (95% CI 2.3% to 5.3%) for etomidate and 7.9% (95% CI 6.1% to 9.7%) for propofol. Clinical events related to respiratory depression included an increase in supplemental oxygen in 6.7% of etomidate patients and 5.5% of propofol patients (difference 1.2%; 95% CI -5.2% to 7.6%), the use of bag-valve-mask apparatus in 3.8% of patients in the etomidate groups and 4.6% in the propofol group (difference -0.8%; 95% CI -6.1% to 4.6%), airway repositioning in 13.3% of etomidate patients and 11.0% of propofol patients (effect size 2.3%; 95% CI -6.4% to 11.1%), and stimulation to induce breathing in 11.4% of etomidate patients and 11.9% of propofol patients (difference -0.5%; 95% CI -9.1% to 8.1%). The procedures were successful in 93 of 105 (88.6%) for etomidate and 106 of 109 (97.2%) for propofol (difference -7.4%; 95% CI -14.3% to -1.1%). CONCLUSION: Etomidate and propofol appear equally safe for ED procedural sedation; however, etomidate had a lower rate of procedural success and induced myoclonus in 20% of patients.
