Evaluation of active compression-decompression CPR in victims of out-of-hospital cardiac arrest.

OBJECTIVE--Active compression-decompression (ACD) cardiopulmonary resuscitation (CPR) appears to improve ventilation and coronary perfusion when compared with standard CPR. The objective was to evaluate potential benefits of this new CPR technique in patients with out-of-hospital cardiac arrest in St Paul, Minn. DESIGN--Ten-month, prospective, randomized parallel-group design. SETTING--St Paul, Minn, population 270,000. PATIENTS--All normothermic victims of nontraumatic cardiac arrest older than 8 years who received CPR. MAIN OUTCOME MEASURES--Return of spontaneous circulation, admission to the intensive care unit (ICU), return of baseline neurological function (alert and oriented to person, place, and time), survival to hospital discharge, survival to hospital discharge with return of baseline neurological function, and complications. RESULTS--Seventy-seven patients received standard CPR and 53 patients received ACD CPR. The mean emergency medical services call response interval was less than 3.5 minutes. When all patients were considered, a higher percentage of ACD CPR patients had a return of spontaneous circulation and were admitted to the ICU vs standard CPR (45% vs 31%, and 40% vs 26%, respectively), but these trends were not statistically significant (P < .10 and P < .10). No statistically significant differences were found between hospital discharge rates (12 [23%] of 53 for ACD CPR vs 13 [17%] of 77 for standard CPR), return to baseline neurological function (10 [19%] of 53 for ACD CPR vs 13 [17%] of 77 for standard CPR), or return to baseline neurological function at hospital discharge (nine [17%] of 53 for ACD CPR vs 12 [16%] of 77 for standard CPR). Return of spontaneous circulation, ICU admission, and neurological recovery in both CPR groups were highly correlated with downtime (time from collapse to emergency medical system personnel arrival to the scene in witnessed arrests). With less than 10 minutes' downtime, survival to the ICU was 59% (19/32) with ACD CPR and 33% (16/49) with standard CPR (P < .02), return to baseline neurological function was 31% (10/32) with ACD CPR and 20% (10/49) with standard CPR (P = .27), and hospital discharge rate was 38% (12/32) with ACD CPR and 20% (10/49) with standard CPR (P = .17). Complication rates in patients admitted to the hospital were similar in both groups. CONCLUSIONS--This study demonstrates that ACD CPR appears to be more effective than standard CPR in a well-defined subset of victims of out-of-hospital cardiac arrest during the critical early phases of resuscitation. Based on this study, a larger study should be performed to evaluate the potential long-term benefits of ACD CPR.

Hepatitis B vaccine and hepatitis B markers: cost effectiveness of screening prehospital personnel.

The purpose of this study was to evaluate the cost effectiveness of screening emergency medical technicians (EMTs) and paramedical personnel prior to administering hepatitis B vaccine. Hepatitis B screening and Heptavax vaccine were offered to 259 basic EMTs and paramedics. Of the 259 individuals, 62 refused screening, and six who had already received hepatitis B vaccine were excluded from the study. The screening was not continued after the results of the first 174 tests returned negative. All 191 participants were vaccinated. No hepatitis B surface antigen carriers and only three individuals positive for hepatitis B surface antibody were found among those screened. This study corroborates the Centers for Disease Control guidelines of cost effectiveness in screening prehospital health care workers.

Open treatment of fingertip amputations.

Twenty-five patients with fingertip injuries at or distal to the distal interphalangeal joint were treated with a thorough cleansing of the wound with application of bacitracin and a sterile dressing. Warm soaks were begun 48 hours after injury. Crush injury was the most common type of trauma, followed by cutting injuries. Bone involvement was present in six cases. The average healing time was 29 days. At the time of complete healing, sensation was normal in 22 patients (88%). Systemic antibiotics were not administered routinely. No patient developed a wound infection. Our study documents that fingertip amputations can be successfully treated by nonoperative methods that result in preservation of finger length and contour, retention of sensation, and healing without infection.

Complication rates for the esophageal obturator airway and endotracheal tube in the prehospital setting.

PURPOSE: The purpose of this study was to determine the complication rates associated with the use of the endotracheal tube (ET) and the use of the esophageal obturator airway/esophageal gastric tube airway (EOA/EGTA) during the treatment of patients with prehospital cardiac arrest. METHODS: A descriptive, quasi-experimental study of 509 consecutive adults, cardiac arrest patients was conducted. Patients were examined prospectively for airway intervention type and complications. Some patients were examined at their final destinations (field, morgue, funeral home), while other patients were examined by EMS providers in the field when airway adjuncts were switched. Also, airways were evaluated for complications by emergency physicians at destination emergency departments. RESULTS: The airway in use at the time of examination was the esophageal obturator airway (EOA) or esophageal gastric tube airway (EGTA) in 208 patients (40.1%); the ET (endotracheal tube) in 232 patients (45.6%); and an oral or nasopharyngeal airway in 47 patients (9.2%). Twenty-two patients (4.3%) had both an EOA/EGTA and an ET tube in place at the time of the examination. The survival rates were similar between the EOA/EGTA and the ET groups (28% and 32%, respectively). The complication rates overall also were similar, but the serious or potentially lethal complication rate was 3.3 times more common with the use of the EOA/EGTA than with the ET tube (8.7% versus 2.6%, respectively). CONCLUSIONS: The complication rate for the EOA/EGTA is unacceptably high, and careful thought must be given to its continued use.(ABSTRACT TRUNCATED AT 250 WORDS)
