Palliative care in a national cancer center: results in 1987 vs. 1993 vs. 2000.

In the last few years, palliative care for advanced and terminal cancer patients has undergone considerable evolution. We determined the characteristics of patients admitted to the 4-bed Palliative Care Unit (PCU) of the National Cancer Institute (NCI) of Milan in 1987, 1993 and 2000 to evaluate how our diagnostic and therapeutic approaches have changed over the years. We reviewed the charts of every patient admitted to the PCU in 1987, 1993, and the first ten months of 2000. We recorded demographic data; the primary tumor sites; the main reason for admission; the types of therapies administered (oncologic, analgesic, surgical, neurosurgical analgesic procedures, and supportive therapy); the type and number of cardiological, radiological and endoscopic examinations, as well as specialist consultations; the duration of stay and eventual death on the Unit. There were no significant differences regarding gender, age, primary tumor site and death in hospital of the patients admitted during these years. The time spent in hospital increased over time (P = 0.006). A significant increase was observed in the percentage of patients admitted for supportive therapy (P < 0.001) and investigation concerning the stage of the disease (P < 0.001). There was a significant decrease in admission for invasive analgesic procedures (P < 0.001), as well as for pain diagnosis and/or uncontrolled pain. Uncontrolled pain remained the most frequent reason for admission. Over the years, during hospitalization, 7% to 12% of the patients underwent radiotherapy,1% to 9% had computerized tomography, and 4% to 8% had palliative surgery. More than 50% of the patients received intravenous hydration; a few patients received hypodermoclysis in 1987. Over time, there was a significant increase in "as needed" administration of nonsteroidal anti-inflammatory drugs and a significant reduction in their regular administration (from 24% in 1987 and 1993 to 3% in 2000) (P < 0.001). The use of codeine, tramadol and methadone increased (P < 0.001), whereas the use of oral morphine, buprenorphine and oxycodone decreased in 2000 (P < 0.001). There was a reduction in the use of antidepressants (no significant constant trend) and a significant increase in the use of anticonvulsants, laxatives and pamidronate (P < 0.001). Regularly administered hypnotics decreased in 1993 and increased in 2000 (P < 0.001). Over these years, no significant differences were found in the routes of opioid administration, in route switching and in the mean maximum oral opioid dose (ranging from 108 to 126 mg/day). The percentage of patients undergoing percutaneous cordotomy significantly decreased in 1993 and 2000 (P < 0.001). Over time, there was an increase in requests for specialist consultations, which was significant for neurological, cardiological and oncological consults (P < 0.001). Although the characteristics of the patients admitted to the PCU did not change over these years, there have been significant modifications in our therapeutic approaches, above all in the use of supportive therapy, adjuvant drugs, opioids and neurosurgical invasive procedures. Moreover, a major collaborative interaction with other specialists of the NCI took place with the aim to tailor treatment for each single patient.

Neuropsychological effects of long-term opioid use in chronic pain patients.

Opioids are thought to worsen the performance of psychomotor tasks due to their sedating and mental-clouding effects. As a result, some safety regulations currently restrict the use of opioids when driving or using heavy equipment. We investigated the psychomotor effects of long-term opioid use in 144 patients with low back pain. All subjects were administered two neuropsychological tests (Digit Symbol and Trail Making Test-B) before being prescribed opioids for pain; tests were re-administered at 90- and 180-day intervals. Test scores significantly improved while subjects were taking opioids for pain, which suggests that long-term use of oxycodone with acetaminophen or transdermal fentanyl does not significantly impair cognitive ability or psychomotor function.

The pain of haemorrhoidectomy: a prospective study.

The efficacy of a multimodal analgesic approach for ligation excision haemorrhoidectomy was evaluated in a prospective series of 62 patients. Opioid was given as intravenous fentanyl intra-operatively, as part of a standardised general anaesthetic technique, followed by post-operative parenteral fentanyl or oral oxycodone as required. Pre-emptive local anaesthesia was provided via ischiorectal fossae and haemorrhoid pedicle infiltration. The non-steroidal anti-inflammatory drug indomethacin was administered rectally at the end of surgery and regularly orally for 5 post-operative days. A wide range of pain scores was recorded post-operatively but all mean scores were between 2 and 3. Pain was highest at the time of the first bowel action but this was successfully managed in the patient's home. Patient satisfaction with their pain management was achieved in 95% of patients. We conclude that the multimodal analgesia technique combined with pre-operative patient education leads to successful pain control following haemorrhoidectomy.

Severe, childhood-onset, idiopathic, life-long insomnia responding selectively to opiate therapy: case report with 19 year follow-up.

BACKGROUND: Idiopathic (primary) insomnia can be difficult to treat; only two prior cases responsive to opiate therapy have been reported. A case is now presented of severe, idiopathic, childhood-onset, familial insomnia, with increased libido, absence of psychopathology, tardive emergence of restless legs syndrome (RLS), and selective response to opiate therapy. CASE REPORT: A 39-year-old woman was referred in 1981 by her physician who had discovered 3 years earlier that propoxyphene treatment of migraines also controlled her chronic insomnia. She had experienced severe insomnia since childhood, and during early adulthood the insomnia intensified, as she would sleep 0-3 h nightly and never napped. Daily generalized motor restlessness resulted in her frequently walking around the house while feeling exhausted. The quality of her life was considerably compromised by her insomnia, motor restlessness, and by an increased libido that was present since puberty and that was only partially relieved by having sex repeatedly with her husband. RESULTS: Nightly opiate therapy for 19 years has controlled the insomnia, motor restlessness, and excessive libido without affecting her normal libido. The insomnia had not responded to treatment with >25 agents covering >10 pharmacologic categories. During her first (unmedicated) polysomnographic (PSG) study in 1981, she slept 0 min while spending 436 min in bed. In 1984, four consecutive PSG studies were conducted in a design that confirmed the efficacy of propoxyphene therapy of her insomnia. In 1990, an ambulatory PSG revealed two runs of EEG rhythmic paroxysmal activity arising from sleep and wakefulness, without clinical correlate. Neurologic history was negative for seizures, but positive for complete right carotid artery occlusion and three transient ischemic attacks. At age 55 years, typical RLS emerged that was controlled with levodopa therapy, and a concurrent relapse of insomnia was controlled with oxycodone replacing propoxyphene. CONCLUSIONS: Nightly opiate therapy of severe idiopathic (primary) insomnia can remain effective during very long-term clinical follow-up. Guidelines are provided for when to consider such an unusual treatment in other cases of severe, chronic insomnia.

10-Ketonaltrexone and 10-ketooxymorphone.

Ethylketocyclazocine (1) has greater kappa/mu selectivity than cyclazocine in brain binding assays. 10-Ketonaltrexone (11) and 10-ketooxymorphone (10) were prepared from naltrexone 3-methyl ether and oxycodone, respectively. Bioassays in the myenteric plexus longitudinal muscle preparation of the guinea pig ileum and in the mouse vas deferens, in addition to brain binding assays, demonstrated that 10 and 11 were far less potent than naltrexone (2) and oxymorphone (3) at mu sites and also had little affinity for kappa and delta sites. It is concluded that introduction of the 10-keto group in naltrexone and oxymorphone diminished opioid effects at all binding sites.

4'-Arylpyrrolomorphinans: effect of a pyrrolo-N-benzyl substituent in enhancing delta-opioid antagonist activity.

A new method for the preparation of N-benzylpyrrolomorphinans has been developed. Thus Michael reaction of the benzylimines of oxycodones and oxymorphones with nitrostyrenes gave a series of 4'-aryl-N-benzylpyrrolomorphinans. These were selective delta antagonists of much higher in vitro potency (with 5a having K(e) delta = <1 nM) than their binding affinities predicted. In mice in vivo assays 5a showed good delta antagonist activity in the anti-writhing analgesic assay and also inhibited delta agonist-induced convulsant activity.

Nocturnal body movements and hypoxemia in middle-aged females after lower abdominal surgery under general anesthesia: a study with the static-charge-sensitive bed (SCSB).

OBJECTIVE: The aim of this study was to evaluate the feasibility of the static-charge-sensitive-bed (SCSB) combined with pulse oximetry (SpO2) for postoperative monitoring and to determine variables which could be used for evaluating the quality of postoperative sleep and breathing. METHODS: The frequency of body movements and the perioperative breathing abnormalities were assessed using the SCSB and pulse oximeter in 15 female ASA-class I-II patients undergoing elective lower abdominal surgery under general anesthesia. Anesthesia and control of postoperative pain followed standard practice. The patients were monitored during one preoperative and three consecutive postoperative nights. Movements were analyzed according to their duration and time interval. The effect of opioids was evaluated by measuring arterial oxyhemoglobin saturation (SpO2) with pulse oximetry for one hour before and two hours after administration of standard doses of oxycodone. RESULTS: The total movement time per hour increased during the first postoperative night (p = 0.003). Conversely, periodic movement activity decreased significantly during the three postoperative nights (p = 0.05, p < 0.001, p = 0.007). The mean SpO2 decreased during the first postoperative night (95.5% vs. 94.2%, p = 0.002), but returned to the preoperative level during the following nights. No episodes of apnea with significant oxygen desaturation (a decrease in SpO2 > 5%) were observed. Opioid administration was associated with decreased mean SpO2 (94.8% vs. 93.6%, p = 0.02), but did not lead to clinically significant hypoxemia (lowest observed SpO2 89.8%). CONCLUSIONS: Postoperative periodic movement activity was suppressed, but sleep remained fragmented with frequent body movements. In our middle-aged non-obese females (ASA I-II), no severe postoperative hypoxemia was observed during the three-nights postoperative survey. Perioperative movement monitoring with the SCSB was a valuable tool in rejecting movement artefacts of SpO2 and in evaluating general sleep quality.

Epidural infusion of bupivacaine and fentanyl reduces perioperative myocardial ischaemia in elderly patients with hip fracture--a randomized controlled trial.

BACKGROUND: Perioperative myocardial ischaemia is an important risk factor for cardiac morbidity and mortality after noncardiac surgery. The impact of analgesic management on the incidence and severity of cardiac ischemia was studied in 77 elderly patients undergoing surgical treatment of traumatic hip fracture. METHODS: After hospital admission and written consent, patients were randomised to conventional analgesic regimen (intramuscular oxycodone, OPI group) or continuous epidural infusion of bupivacaine/fentanyl (EPI group). The analgesic regimens were started preoperatively. Patients were operated under spinal anaesthesia and the treatments were continued three days postoperatively. ECG was continuously recorded. ST segment depression of > or = 0.1 mV or elevation of > or = 0.2 mV lasting > or = 1 min were considered as ischaemic episodes. Nocturnal arterial oxygen saturation (SaO2) was recorded perioperatively, and subjective pain was assessed every morning using a visual analogue scale (VAS). RESULTS: Fifty-nine (OPI 30, EPI 29) patients were evaluable for efficacy. Thirteen patients (43%) in the OPI and 12 patients (41%) in the EPI group had ischaemic episodes (NS). However, significantly more patients in the OPI group had ischaemic episodes during the surgery (8 vs. 0 in the EPI group, P=0.005). The median (quartal deviation) total ischaemic burden (i.e. integral of ST-change vs. time) in patients with ischaemic episodes was ten times larger in the OPI group (340 [342] mm x min) compared with the EPI group (30 [36] mm x min) (P=0.002). There were no significant differences between the groups in average heart rates or in heart rates at the start of ischaemic episodes or in maximal heart rates during the attacks. Average nocturnal SaO2 was similar in the two groups and there were no differences in the number of hypoxaemic (SaO2<90%) episodes. Preoperatively there were no differences in subjective pain, but postoperative and average perioperative VAS scores for pain were almost 40% lower in the EPI group (P=0.006). Perioperative myocardial infarctions were not detected. CONCLUSIONS: Continuous epidural bupivacaine/fentanyl analgesic regimen, started preoperatively, reduces the amount of myocardial ischaemia in elderly patients with hip fracture.

Nasal administration of opioids for pain management in adults.

BACKGROUND: Nasal administration of opioids may be an alternative route to intravenous, subcutaneous, oral transmucosal, oral or rectal administration in some patients. Key features may be self-administration, combined with rapid onset of action. The aim of this paper is to evaluate the present base of knowledge on this topic. METHODS: The review is based on human studies found in Medline or in the reference list of these papers. The physiology of the nasal mucosa and some pharmaceutical aspects of nasal administration are described. The design of each study is described, but not systematically evaluated. RESULTS: Pharmacokinetic studies in volunteers are reported for fentanyl, alfentanil, sufentanil, butorphanol, oxycodone and buprenorphine. Mean times for achieving maximum serum concentrations vary from 5 to 50 min, while mean figures for bioavailability vary from 46 to 71%. Fentanyl, pethidine and butorphanol have been studied for postoperative pain. Mean onset times vary from 12 to 22 min and times to peak effect from 24 to 60 min. There is considerable interindividual variation in pharmacokinetics and clinical outcome. This may partly be due to lack of optimization of nasal formulations. Patient-controlled nasal analgesia is an effective alternative to intravenous PCA. Adverse effects are mainly those related to the opioids themselves, rather than to nasal administration. Some experience with nasal opioids in outpatients and for chronic pain has also been reported. CONCLUSION: Nasal administration of opioids has promising features, but is still in its infancy. Adequately designed clinical studies are needed. Improvements of nasal sprayer devices and opioid formulations may improve clinical outcome.

Controlled clinical trials in cancer pain. How controlled should they be? A qualitative systematic review.

This qualitative systematic review of the clinical methodology used in randomised, controlled trials of oral opioids (morphine, hydromorphone, oxycodone) for cancer pain underlines the difficulties of good pain research in palliative care. The current literature lacks placebo-controlled superiority trials. Recommendations for future research are discussed.

Opioid analgesic prescribing and use - an audit of analgesic prescribing by general practitioners and The Multidisciplinary Pain Centre at Royal Brisbane Hospital.

AIMS: This study evaluated the use of and need for opioids in patients attending the Multidisciplinary Pain Centre at the Royal Brisbane Hospital (RBH). METHODS: All consecutive in-patient admissions in 1998 were reviewed. A 10-point scoring system based on the World Health Organization (WHO) analgesic ladder was devised to facilitate comparison of analgesic prescribing on admission and at the time of discharge. A conversion table was used to standardize opioid analgesic doses to an oral morphine equivalent. RESULTS: Of the 370 patients reviewed, 233 (81%) were by their general practitioners. Records of 288 (78%) were available for full review and 270 (94%) of these had noncancer pain. On admission, 239 (83%) were taking an opioid analgesic, with 135 (47%) taking strong opioids (e.g. morphine, oxycodone, methadone). There was a significant decrease in the mean total daily oral morphine equivalent prescribed on discharge 36.9 mg (95% CI: 33.4, 40.4) compared with that on admission 88.7 mg (95% CI: 77.6, 99.8) (P < 0.001). There was a significant decrease (P < 0.05) in the proportion of patients taking a primary opioid on discharge 153 (58%) compared with admission 239 (83%), although the proportion of patients taking a strong opioid on discharge 150 (52%) compared with admission 135 (47%) was not significantly different (P > 0.05). The proportion of patients taking a laxative showed a significant increase on discharge 110 (73%) compared with admission 38 (28%) (P < 0.05). CONCLUSIONS: Our analgesic prescribing scoring system and opioid conversion table have the potential to be developed further as tools for assessing opioid analgesic prescribing. The significant decrease in total daily oral morphine equivalents signifies the value of prescribing in accordance with the WHO analgesic ladder, and the necessity of general practitioner education. The management of chronic pain is complex, and it requires interventions additional to pharmacological therapy. Evaluation by a multidisciplinary team, coupled with experience in and an understanding of analgesic prescribing and rehabilitation provides an effective basis for improving the management of patients with chronic pain.

Single-blind randomized clinical trial of laparoscopic versus open appendicectomy in children.

BACKGROUND: Appendicectomy is the most common emergency surgical operation in children. The aim of this study was to compare recovery after appendicectomy using either a laparoscopic or an open technique in children. METHODS: Sixty-one children aged 4-15 years undergoing appendicectomy for suspected uncomplicated appendicitis were studied. The study was prospective, randomized and single-blinded, with parallel groups. Standardized anaesthetic technique and pain management were used. The study endpoints were postoperative pain, need for rescue analgesia, and length of hospital stay. RESULTS: Children had significantly less pain after laparoscopic compared with open appendicectomy 8 h after operation and on the first and second postoperative mornings (P < 0.05). Laparoscopic appendicectomy resulted in a reduced requirement for rescue analgesia with oxycodone in hospital: mean(s.d.) 3.6(2.5) versus 5.8(3.3) doses (mean difference 2.2 doses, 95 per cent confidence interval (c.i.) 0.6--3.8 doses); P = 0.01. The mean(s.d.) length of hospital stay was significantly shorter in the laparoscopic group: 1.9(0.7) versus 2.6(0.9) days (mean difference 0.7 days, 95 per cent c.i. 0.3--1.1 days); P = 0.001. Three children who had open appendicectomy developed a wound infection. CONCLUSION: Laparoscopic appendicectomy is associated with less postoperative pain and a shorter hospital stay than open appendicectomy in children undergoing surgery for uncomplicated appendicitis.

Opiate and opioid use in patients with refractory headache.

Opiate and opioid analgesics are commonly used for pain in general and presumably for headache. Codeine, oxycodone and propoxyphene, among the most commonly prescribed, do carry some risk of abuse, and their efficacy in headache patients has not been well studied. In many patients with other kinds of pain, however, both of neoplastic and non-neoplastic origin, chronic opiate use has been demonstrated to be of benefit without adverse side effects. The type of headache patient with intractable pain who needs frequent opiate analgesic and who does not develop addiction or drug abuse is an important subject for research.

Methadone and the hospice patient: prescribing trends in the home-care setting.

OBJECTIVE: To identify frequency and utilization patterns of methadone by hospice patients in the home-care setting. PATIENTS AND SETTING: All hospice patients admitted to a North American palliative care specialty pharmacy and dispensed methadone from November 1, 2001 to October 31, 2002 were analyzed. We also analyzed all hospice patients dispensed long-acting opioids during that same time period. DESIGN: A retrospective analysis of the pharmacy database was performed for patients dispensed methadone. Data was compared to the long acting opioid cohort to be able to identify any difference in terminal diagnoses present, and the presence of neuropathic pain in both groups. Methadone daily dosage was also analyzed during this study. RESULTS: Four hundred sixteen hospice patients were dispensed methadone over a twelve-month period of time. For comparison, 21,219 patients were prescribed a long-acting opioid preparation (sustained-release morphine, sustained-release oxycodone, or transdermal fentanyl). The most common terminal diagnosis for both groups was lung carcinoma. The distribution of terminal diagnoses was similar in both groups. The group prescribed methadone was found to have a higher incidence of neuropathic pain (30.5% of patients) when compared to the long-acting opioid group (16.9%). Most patients (61.3%) were prescribed daily methadone doses of 100 mg or less. CONCLUSIONS: Despite its potential clinical and economic benefits, methadone is not commonly prescribed for the hospice patient in the home-care setting. Clinicians may be more aware of the usefulness of methadone in the treatment of neuropathic pain.

[Development of opioid tolerance -- molecular mechanisms and clinical consequences].

INTRODUCTION: One often identified effect of opioid administration is that of the development of tolerance to the analgesic effect. While it is generally agreed that tolerance to opioid analgesia does occur, it does not appear to be a limiting factor. Dose escalation in chronic pain therapy is considered to be predominantly a consequence of increasing pain, which is a result of increasing nociceptive input as the disease progresses. The underlying cause of tolerance to opioids, however, as commonly identified in the ICU can be identified as an adaptation process. When the opioid is given continuously several causes of adaptation can be identified, all of which can be traced back to the cellular and molecular level. RECEPTOR RELATED CHANGES INVOLVED IN TOLERANCE: Initial effects of opioid administration in most individuals are analgesia, sedation, nausea/vomiting, respiratory depression, pupillary constriction, constipation and euphoria or dysphoria. However, numerous studies and clinical experience suggest that tolerance to different opioid effects develop at different rates, which has been termed selective tolerance. While tolerance to nausea, vomiting, sedation, euphoria and respiratory depression occur rapidly, there is minimal development of tolerance to constipation and miosis. Such diversity suggest receptor-related differences in the speed of development of tolerance. In the ICU other compounds such as benzodiazepines, when given together with opioids, seem to speed up the rate of development of tolerance of the latter. Such an effect very likely is due to a reduction in activity of the descending inhibitory nervous system. In addition, there is surmountable data suggesting that the higher the intrinsic activity of the opioid at only one receptor site, lesser receptors are needed in order to induce a potent analgesic effect. As a net result the incidence of tolerance is less likely to become clinically apparent when potent ligands such as fentanyl or sufentanil are administered. N-METHYL-D-ASPARTATE (NMDA) ACTIVATION, OPIOID RECEPTOR INTERNALIZATION AND DESENSITIZATION: An altered metabolism has little effect on the rate of development of tolerance. In chronic pain treatment with morphine, however, an increased ratio of the metabolite morphine-3-glucuronide, with antiopioid effects, to morphine-6-glucuronide is associated with staggering doses of the analgesic. Opioids which interact with micro - and/or kappa-binding sites, demonstrate an adaptation process called desensitization which is due to a reduced interaction with the internal second messenger system called G-protein. This is only a short-lived phenomenon following binding of the ligand. Another underlying mechanism of tolerance development is that of internalization of the opioid receptors. This short-lived phenomenon, termed endocytosis, results in lesser binding sites available for the mediation of analgesia. Another and more relevant mechanism of long-term opioid binding is that of subsequent protein kinase C (PKC), phospholipase C (PLC) translocation and activation of nitric oxide synthetase (NOS). All of this contributes to a N-methyl-D-aspartate (NMDA) receptor activation with ensuing antiopioid effect and tolerance. CLINICAL CONSEQUENCES FOLLOWING THE DEVELOPMENT OF TOLERANCE: Most likely genetic difference in opioid receptor synthesis and difference in their affinities for various ligands is the cause for the wide margin of dose variability in patients (genetic polymorphism). Once tolerance to the analgesic effect of the opioid is observed and in order to avoid unnecessary further development of tolerance, simultaneous administration of other receptor mediated analgesics is advocated. In the perioperative period strategies like the multimodal analgesic concept is fostered. It consists of the simultaneous administration of low-dose ketamine, co-administration of an alpha 2-agonist, and the administration of a selective COX-2 inhibitor (refecoxib, parecoxib) respectively. In chronic pain therapy combined administration with either dextromethorpharphane, or opioid rotation of a more potent ligand such as methadone, fentanyl TTS or oxycodone is suggested. Since conversion factors are not reliable in opioid rotation, it is best to start off with 50 % of the equivalent dose and rapidly titrate to the desired effect. With regard to tolerance development in the ICU, co-administration of an alpha 2-agonist (clonidine, dexmedetomidine), and daily intermittent cessation of benzodiazepine administration are advocated. Since continuous dosing of an opioid, commonly handled in the ICU setting is more likely to induce tolerance, intermittent administration is advocated. Taken together, there is an abundance of experimental data which suggests, that with every dose of an opioid several adaptive processes are being initiated. Due to genetic polymorphism such adaptation is seen clinically with striking individual different dosages, the degree and the time of onset of tolerance. Although tolerance development may result in staggering doses of an opioid, there is no reason to evade the use of such agents. On the contrary, the concept of multimodal analgesia consisting of the simultaneous use of analgesics with a different mode of action can counteract tolerance development.

Ethical issues in the management of chronic nonmalignant pain.

Chronic pain represents a challenge to patients, families, employers, and the physicians who care for these individuals. Opioids remain the mainstay of the analgesic medications for the treatment of both acute and chronic pain. Controlled release preparations of morphine, oxycodone, fentanyl and long acting opioid agents such as methadone and levorphanol have been medically and ethically accepted in managing chronic cancer pain. However, the continued use of these medications for patients with chronic noncancer pain has been fiercely debated. This article attempts to reconcile the medical and ethical dilemma of using opioid medications for chronic noncancer pain. Growing clinical experience in the field of pain medicine has helped to clarify: (1) the misunderstanding of addiction, physical dependence and analgesic tolerance, (2) the misconception that chronic opioid therapy inevitably causes personality changes, depression, and impairment of cognitive and physical function, (3) the lack of information on the correct use of opioid analgesics with regard to titration and management of related side effects. The behavioral management of pain patients undergoing chronic opioid therapy is also discussed. A protocol for optimal patient management is proposed. Particular emphasis is given to the consent form, behavioral contracting, and the consequences of noncompliance. The importance of psychologic evaluation before a long-term opioid trial, to minimize future complications, is stressed. Although most patients on the opioid regimen do well, special attention must be given to patients with current addiction, a past history of addiction, or current misuse of opioid medications. Pharmacologic and conservative interventions are often warranted in those patients with significant behavioral problems. If such strategies fail, and chronic opioid therapy is deemed necessary, some treatment guidelines are offered.

A retrospective study of the effect of postoperative indomethacin rectal suppositories on the need for narcotic analgesia in patients who had a cesarean delivery while they were under regional anesthesia.

OBJECTIVE: This study was undertaken to assess the efficacy of rectal indomethacin as an analgesic after cesarean delivery, comparing narcotic usage in patients receiving indomethacin with patients who received only standard narcotic analgesics. STUDY DESIGN: A retrospective study of patient records consisting of 297 women who underwent cesarean delivery while they were under regional anesthesia in a medium-sized community hospital from February 1996 through December 1999. Narcotic usage was determined as morphine equivalents whereby 10 mg morphine sulfate equals 30 mg oxycodone equals 50 mg hydrocodone equals 75 mg meperidine. Indomethacin was administered as 50-mg rectal suppositories. Statistical analysis was done by Pearson correlation and independent Student t test analysis. RESULTS: Narcotic usage was reduced by an average of 16 morphine equivalents (28%) in the indomethacin group. Pearson correlation revealed correlation at the.01 level; independent Student t test analysis revealed a P value of.001. Thus the mean amount of narcotic analgesic administered was significantly less in patients treated with indomethacin rectal suppositories. CONCLUSION: In this uncontrolled trial the use of indomethacin rectal suppositories resulted in a significant reduction in narcotic use in the postcesarean hospital recovery period as measured in morphine equivalents.
