The efficacy and safety of two dose levels of FS 205-397 (either 250 or 500 mg) were compared with the efficacy and safety of aspirin 650 mg and placebo in a 6-hour, single-dose, double-blind study in 161 patients who had undergone extraction of third molars. Each of the doses of FS 205-397, as well as aspirin, produced analgesia. However, the analgesic effects of both the 500 mg dose of FS 205-397 and aspirin were at times significantly better and more prolonged than those produced by the lower dose of FS 205-397. On the other hand, both doses of FS 205-397 had a significantly faster onset of action than aspirin. Side effects, reported by 17% of the 161 patients, did not differ significantly among the four treatment groups with respect to frequency, type, or severity. The most commonly reported side effects were nausea (7%) and drowsiness (6%). The results indicated that FS 205-397, administered in single doses of either 500 or 250 mg, is a safe and effective analgesic for the relief of pain following dental surgery, and may offer particular advantages in terms of onset of effects.

Few advancements in postoperative pain control in children have been made despite longstanding inadequacies in conventional intramuscular analgesic regimens. While overestimating narcotic complication rates, physicians often underestimate efficacious doses, nurses are reluctant to give injections, and many children in pain shy away from shots. This study prospectively focuses on the safety, efficacy, and complication rate of intermittent intramuscular (IM) versus continuous intravenous infusion (IV) of morphine sulfate (MS) in 46 nonventilated children following major chest, abdominal, or orthopedic surgical procedures. Twenty patients assigned to the IM group had a mean age of 6.17 years and a mean weight of 23.0 kg. Twenty-six patients assigned to the IV group had a mean age of 8.74 years and a mean weight of 27.4 kg. The mean IM MS dose was 12.3 micrograms/kg/h while the mean IV dose was 19.8 micrograms/kg/h (P less than .001). Postoperative pain was assessed with a linear analogue scale from 1 to 10 (1, "doesn't hurt"; 10, "worst hurt possible") for 3 days following operation. Using the analysis of covariance (ANACOVA), nurse, parent, and patient mean pain scores in the IV group were significantly lower than those of the IM group when controlled for age, MS dose, and complications (P less than .007). Nurse assessment of pain correlated well with the patient and parent assessments (Pearson correlation coefficients greater than 0.6). Not only did IV infusion give better pain relief than IM injections, but there were no major complications such as respiratory depression. Minor complications in this study (nausea, urinary retention, drowsiness, vomiting, hallucinations, lightheadedness, and prolonged ileus) were not significantly different between IM and IV groups.(ABSTRACT TRUNCATED AT 250 WORDS)

In a prospective randomized study we evaluated the opinion of 97 parturients on either epidural analgesia or parenteral pethidine with respect to analgesic efficacy, general feelings and symptoms during labour and delivery. The analgesic effect of the epidural block was significantly superior to pethidine with regard to the pain score (visual analogue scale (VAS)0 during the first stage of labour (mean VAS 11 contrasting 65). Moreover, 30 (59%) women in the epidural group compared to 9 (20%) in the pethidine group had a painless labour and delivery. Significantly more parturients (37 (73%)) in the epidural group would request an epidural blockade rather than pethidine treatment (14 (30%)) in a subsequent labour. Fewer side effects were registered in the epidural group compared to the pethidine group, however only significantly concerning sleepiness. It is concluded that in this study low-dose epidural analgesia during the first stage of labour was superior to parenteral pethidine regarding pain relief and side effects.

Several important developments were reported at the 1989 Annual Meeting of the American Society of Anesthesiologists: (1) a computerized machine called HealthQuiz asks patients health questions, and in less than 10 minutes provides a printout of answers, a summary of symptoms, and a list of suggested laboratory tests; (2) a simple device provides continuous measurements of a critically ill patient's oxygen and carbon dioxide levels; (3) near-infrared reflectance is a new technique that may provide the first accurate real-time measurement of critical oxygen levels in the brain; (4) pulse oximeters may provide false readings in patients who smoke cigarettes; (5) a new test may accurately predict the survival chances of a child in a coma; (6) the fastest growing subspecialty in anesthesiology is chronic pain management clinics; (7) alpha-2 adrenergic agonists improve pain relief without the unwanted side effects of narcotics; (8) clonidine appears to suppress the dangerous shivering that often occurs in postanesthesia patients; (9) flumazenil was successfully tested as an agent to reverse the drowsiness caused by midazolam; and (10) ephedrine minimizes nausea and vomiting in patients undergoing ambulatory surgery.

This study aimed to compare the efficacy and side-effects of sublingual buprenorphine, a synthetic opioid agonist antagonist, with those of subcutaneous morphine. Fifty ASA class 1 patients were included in the study after having given their informed consent. Caesarean section was carried out under epidural block with 0.5% bupivacaine; no opioids were used during the procedure. The first dose of opioid was given 2 h after the first dose of bupivacaine. Patients were randomly given either 10 mg morphine (n = 25) or 0.4 mg buprenorphine (n = 25), followed by the same dose every 6 h for 36 h. When analgesia was insufficient, tablets containing dextropropoxyphene and paracetamol were given. No attempt was made to blind the study to the patient, but the investigator assessing pain was unaware of the drug given to the patient. Pain intensity was assessed before, and 2 h after each dose of opioid with a 100 mm visual scale, as well as systolic, diastolic and mean arterial blood pressures, heart and breathing rates, and SpO2. Side-effects (pruritus, nausea, vomiting, drowsiness) were also noted. In 2 patients in each group, the protocol was stopped before the 36th h, but after the fourth dose, either because of side-effects, or at the patient's request. Results were similar in both groups of patients, whether for degree of pain relief, or physiological effects. There was no clinically detectable respiratory depression. Duration and intensity of episodes of arterial oxygen desaturation, and the incidence of nausea, were similar in the 2 groups; pruritus was more common in the morphine group.(ABSTRACT TRUNCATED AT 250 WORDS)

A study was undertaken to investigate the use of fentanyl by aerosol for postoperative analgesia. Seven patients had placebo, six received fentanyl 100 micrograms and seven were given fentanyl 300 micrograms. A significant improvement in postoperative pain, as assessed by linear visual analogue scale, was achieved in the higher dose group, and in both fentanyl groups the time to alternative analgesia was significantly longer than in the control group. Serum fentanyl levels after inhalation of 100 micrograms reached a plateau around 0.04 ng/ml and after 300 micrograms at around 0.1 ng/ml after 15 minutes. Inhaled fentanyl may have a useful analgesic effect despite these low serum levels; this supports the hypothesis that the mode of analgesia from inhaled opioids may be different from that after other routes of administration. There were no adverse effects such as respiratory depression, bronchospasm, nausea or drowsiness.

This randomized, double-blind study compared epidural (EP) and intramuscular (IM) morphine in 24 healthy parturients for 24 h after cesarean section. The 11 EP subjects received 5 mg of EP morphine and normal saline intramuscularly, and the 13 IM patients received 5 mg of IM morphine and normal saline epidurally. Both injections were given simultaneously just after delivery and then upon request with at least 30 min between each pair of injections. Blood pressure, visual analogue scale pain score, somnolence score, and presence of nausea, vomiting, or pruritus were assessed every 30 min for 1 h after each dose and then hourly. Oxyhemoglobin saturation (Spo2) and respiratory rate (RR) and pattern were monitored continuously with pulse oximetry and respiratory inductive plethysmography. The EP group had significantly lower pain scores (less pain) than the IM (0.9 +/- 0.3 vs. 3.3 +/- 1.3; mean +/- SD; P less than 0.001) with less morphine (0.3 +/- 0.2 vs. 2.2 +/- 0.6 mg patient-1 h-1; P less than 0.001). There was no difference between groups for RR, Spo2, incidence or frequency of slow respiratory rate (SRR, 5-min mean RR less than 10) and apneas (AP, greater than or equal to 15 s of less than 100 ml tidal volume), incidence of nausea and/or vomiting, pruritus, or hypotension, and hours asleep or drowsy. There were no major respiratory abnormalities. During control monitoring of nine EP and 11 IM subjects while asleep postoperatively, the RR, Spo2, and incidence and frequency of SRR and AP were similar to the study period in both groups. In conclusion, EP morphine was a more effective analgesic than IM morphine, but the side effects of both were similar.

Twenty-five patients with pain due to advanced cancer were randomized to receive patient-controlled sc injections (PCIs) of hydromorphone (HM) versus continuous sc infusion (CSCI) of HM by means of a Pharmacia 5200 pump. Each self-injection of HM during PCI was equivalent to 4 hours of CSCI. After 3 days, a crossover occurred, and patients received the alternate treatment for 3 days. During both phases of the study, patients could request extra doses of HM from their nurses. In 22 patients able to be evaluated, pain intensity (visual analogue, 0-100 mm) at 9:00 a.m. and 4:00 p.m. was 31 +/- 23 and 28 +/- 18 mm, respectively, on PCI versus 28 +/- 18 and 27 +/- 17 mm, respectively, on CSCI [P = not significant (NS)]. The total dose of HM was 168 +/- 197 and 181 +/- 234 mg on PCI and CSCI, respectively (P = NS). No significant difference was found in nausea, drowsiness, or number of hours of sleep. The total number of extra doses of HM was 6 +/- 7 on CSCI versus 2 +/- 3 on PCI (P = .007). At the end of the study, patients chose PCI and CSCI in seven and 10 cases, respectively (P = NS; 5 patients expressed no preference). We conclude that both methods were similar in regard to effectiveness and toxic effects in short-term hospital use.

In order to antagonize immediate postoperative somnolence, 24 surgical patients were given a two-rate infusion of physostigmine, aiming at a constant plasma concentration in the range of 1 to 10 ng/ml. Plasma concentrations of physostigmine were determined during infusion and after infusion and the effects of physostigmine on analgesia and postoperative sedation, and its side effects were monitored throughout. On the 1st postoperative day some of the patients (n = 8) were given 5 mg physostigmine orally, after which plasma concentrations as well as effects were measured. Steady-state concentrations were generally lower than predicted. Clearance varied between 10 and 85 ml/min x kg with a mean of 40.8 +/- 21.0 ml/min x kg. Oral bioavailability was 25.3 +/- 11.1%. Physostigmine administered as an intravenous infusion antagonized immediate postoperative somnolence in 21 out of 24 patients. Effects were poorly correlated with the established steady-state concentration of physostigmine. The patients' experience of postoperative pain relief was mostly satisfactory and the side effects of physostigmine infusion were generally limited. The effects of physostigmine in the immediate postoperative period seemed dependent on the dose as well as on the time which had elapsed since administration of anticholinergic drugs. After oral physostigmine administration the following morning, the majority of patients experienced side effects such as nausea and abdominal pain. In conclusion, physostigmine given as infusion antagonizes postoperative somnolence. However, the arousal effect was considered not better than that resulting from a bolus dose of the drug, although the infusion regimen allowed a prolonged clinical effect duration.

The analgesic efficacy of a single 100-mg suppository of diclofenac sodium given after elective cholecystectomy was studied in 30 healthy patients in a double-blind randomised controlled manner. The mean 24-hour postoperative morphine consumption of the placebo group and the diclofenac group was similar (45 mg). Analysis of the cumulative hourly morphine consumption from the patient-controlled analgesia system failed to show any statistically significant differences between the groups. Peak expiratory flow rate, forced expiratory volume at 1 second and forced vital capacity decreased 24 hours after operation to less than 50% of pre-operative values in both groups. Subjective experiences of pain, nausea and drowsiness assessed by linear analogue scoring were similar in both groups.
