Epidural narcotics has been shown to produce profound and long-lasting analgesia. It has been suggested that lipid-soluble narcotics such as fentanyl, because of their short transit time in the CSF, are less likely to be associated with delayed respiratory depression and side effects. We tried to combine low concentrations of fentanyl with bupivacaine to minimize side effects and to see if synergistic effect existed. Forty ASA physical status I or II patients who present for cholecystectomy were included in the trial. Before surgery a thoracic epidural catheter was inserted and pain control began when patients became fully awake and complained of pain in the recovery room after surgery. Patients were randomized in a double-blind fashion to one of four groups. Patients in group I were given epidural infusions of fentanyl 0.001%; patients in group 2 received fentanyl 0.001% mixed with bupivacaine 0.1%; patients in group 3 received fentanyl 0.0005%; patients in group 4 received fentanyl 0.0005% mixed with bupivacaine 0.1%. A continuous epidural infusion of these drugs began at a rate of 10 mL/h after a 5-mL bolus of the solution. Pain relief was assessed with visual analogue pain scale. Respiratory rates, vital signs, and mental status were assessed hourly. Except the group 3, the degree of analgesia achieved was similarly satisfactory in all other groups. There was no respiratory depression developed in either group. Motor block was minimal or absent in all groups. The incidence of nausea and pruritus was significant less in group 3 and group 4. In conclusion, the continuous infusion of dilute bupivacaine with fentanyl provides synergistic analgesia with minimal side effects.

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)

To determine whether administration of nitrous oxide, 50% and 70%, could provide analgesia and anxiolysis during venous cannulation in pediatric patients, 165 ASA Physical Status 1 patients scheduled for elective surgery were studied. Children, 3 weeks to 18 yr of age, were randomly assigned either to receive nitrous oxide, 50% or 70% in oxygen, or 100% oxygen via mask or to a group breathing room air, for 3 min prior to and during venous cannulation. A blinded observer using a behavioral scale for rating pain in children performed assessments of behavior and pain before and following venous cannulation. Children who received 50% or 70% nitrous oxide were more likely to be relaxed, 59% and 84%, respectively, and had little evidence of pain. Of those given 100% oxygen or no mask, only 30% and 21%, respectively, were considered relaxed, and 16% and 15% had little evidence of pain during venous cannulation. Side effects were seen in 28% of the group given 70% nitrous oxide and included excitement, dysphoria, nausea, restlessness, and opisthotonic movements. Both 50% and 70% nitrous oxide in oxygen administered to pediatric patients are effective at decreasing the pain and anxiety associated with venous cannulation, but use of the latter is associated with side effects.

The frequency of postanesthesia side effects and times to reach "benchmarks" in the recovery process for IV preinduction doses of 20 micrograms/kg butorphanol, 40 micrograms/kg butorphanol, or a 2 micrograms/kg dose of fentanyl were compared in a double-blinded study involving ambulatory surgical patients. The authors hypothesized that all drugs would perform equally well in all study areas. Sixty ASA physical status I and II women undergoing laparoscopic tubal sterilization were randomly assigned to one of three groups: Group I (n = 20) received 20 micrograms/kg butorphanol as a preinduction agent; Group II (n = 20) received 40 micrograms/kg butorphanol; Group III (n = 20) received 2 micrograms/kg fentanyl. Anesthesia management for all groups was the same. Statistically significant variance was found in time to discharge-ready status and duration of nausea (p less than 0.05) between 40 micrograms/kg butorphanol and 2 micrograms/kg fentanyl, but no significant difference was found between 20 micrograms/kg butorphanol and 2 micrograms/kg fentanyl in these areas. Statistically significant variance was found in duration of dizziness and time to obtain a 10 on the Aldrete Post Anesthesia Recovery Score (APARS) between 40 micrograms/kg butorphanol and 20 micrograms/kg butorphanol and 40 micrograms/kg butorphanol and 2 micrograms/kg fentanyl. From the study, 20 micrograms/kg butorphanol appears to be as suitable as 2 micrograms/kg fentanyl for use as a preinduction narcotic analgesic, whereas 40 micrograms/kg butorphanol appears to be unsuitable due to increased duration of nausea, dizziness, and time to score 10 on APARS and reach discharge-ready status.

The side-effects of two opioid agonist-antagonists, nalbuphine and pentazocine, were assessed when used for patient-controlled postoperative analgesia. Forty ASA I or II patients scheduled for upper abdominal surgery were randomly allocated to two equal groups. The anaesthetic technique was the same for all the patients: premedication with atropine and diazepam, induction with thiopentone and suxamethonium and maintenance with fentanyl, pancuronium, nitrous oxide and halothane. Patient-controlled computer assisted analgesia (On-Demand Analgesia Computer) was started in the recovery room at least 2 h after the last administration of fentanyl. The parameters used were: a routine hourly dose (the half of that received during the previous hour), with on demand delivery of nalbuphine (15 micrograms.kg-1) or pentazocine (45 micrograms.kg-1) aliquots respectively, with a refractory period between two demands of 4 min and a total hourly maximum dose of 16 mg and 48 mg respectively. The following parameters were measured before the start of self-administration, and every hour afterwards for 24 h: systolic (Pasys) and diastolic blood pressures, heart rate, pressure-rate product (PRP), respiratory rate, end-tidal CO2 and pain (by way of a three point scale). Analgesia was assessed on a four-point scale every 6 h. The total doses of nalbuphine and pentazocine administered were 94 +/- 43 mg and 251 +/- 150 mg respectively. The only parameters significantly different between the two groups were Pasys and PRP, being higher in the pentazocine group. There were no significant differences in the side-effects (drowsiness, nausea, vomiting, headache, amnesia, logorrhoea and urine retention). All patients in both groups were satisfied with this technique.(ABSTRACT TRUNCATED AT 250 WORDS)

Initial studies have suggested that oral transmucosal fentanyl citrate (OTFC) in a dose of 15-20 micrograms/kg may be a safe and effective preanesthetic medication in children and adults, but this has not been demonstrated in a randomized, double-blind fashion. The purpose of this study was to determine in a randomized, double-blind manner, the efficacy of a lollipop containing fentanyl citrate as a preanesthetic medication before surgery in children. Forty health ASA physical status 1 or 2 children 3-12 yr of age were divided randomly and in double-blind fashion into two groups. Group 1 received the lollipop containing OTFC and group 2 received a placebo lollipop. An appropriate size lollipop was chosen so that if the patient received fentanyl, the total dose would be 15-20 micrograms/kg. Anxiety, sedation, and separation scores were assessed preoperatively and ease of induction was rated. Oxygen saturation and respiratory rate were monitored. Time intervals from preanesthetic to induction and from recovery room (PACU) admission to discharge were noted. Recovery room behavior was assessed upon admission and discharge. Complications and the need for postoperative opioids were noted. OTFC produced significantly more sedation and less anxiety compared with that following placebo. Respiratory rate was significantly decreased in the OTFC group, but oxygen saturation was not significantly different between groups. Anxiety and separation scores and the quality of induction were better in the OTFC group. There was a higher incidence of nausea and pruritus in the fentanyl group. OTFC did not prolong the PACU stay.

Thirty patients with active rheumatoid arthritis (RA) participated in an open study of 6 months' treatment with either 5-aminosalicylic acid (5-ASA) or sulphapyridine (SP), the two moieties of sulphasalazine (SASP). Patients were assessed at regular intervals using clinical and biochemical tests designed to detect specific antirheumatic activity. Patients taking SP showed significant improvement in disease activity, but those taking 5-ASA did not improve, despite the fact that high serum concentrations of 5-ASA and acetyl 5-ASA were achieved. These results suggest that SP is the active moiety of SASP. Its possible mode of action is discussed. Nausea was a frequent problem in patients taking SP. Unless this can be overcome, SP is unlikely to offer any therapeutic advantages over SASP in the treatment of RA.

Patient-controlled analgesia (PCA, intravenous self-application of narcotics) was studied during the early postoperative period. Subjects were 40 ASA I-III patients recovering from elective major and minor surgery (20 each having undergone abdominal or orthopedic operations). Whenever the patients required pain relief, piritramid demand doses of 2.0 mg were given via the hand-button of a microprocessor-controlled injection pump (On-Demand Analgesia Computer, ODAC). Hourly maximum dose was set to 15 mg with a pump refractory time of 1 minute between valid demands. A continuous low-dose piritramid infusion (0.24 mg/h) was additionally administered in order to prevent catheter obstruction. Duration of the PCA period was 19.7 +/- 6.5 hours (mean +/- SD). During this time, 17.1 +/- 13.8 demands per patient were recorded resulting in mean individual piritramid consumptions of 30.4 +/- 28.1 micrograms/kg/h. Self-administration was characterized by considerable intra- and interindividual variability. Following abdominal surgery, slightly more piritramid was needed compared with orthopedic patients, although less pain relief was achieved in the former group. The same proved to be true for a comparison between the sexes, males requiring significantly more piritramide for less pain relief than females (p = 0.05). Over-all efficacy and patient acceptance proved to be excellent. Effectiveness of PCA was judged superior by about 73% of patients when compared with previously experienced conventional postoperative analgesia. Side effects (sweating, nausea, emesis) occurred in about 20% but were usually of minor intensity. No serious circulatory or respiratory problems were observed during the PCA period. Patient-controlled analgesia is discussed as a promising concept for the treatment of acute pain and for clinical pain research.

619 patients with suspected acute myocardial infarction (MI) were randomized to receive either a high-dose short-term intravenous infusion of streptokinase (1.5 MU over one hour) or placebo. Using a '2 X 2 X 2 factorial' design, patients were also randomized to receive either oral aspirin (325 mg on alternate days for 28 days) or placebo, and separately randomized to receive either intravenous heparin (1000 IU h-1 for 48 hours) or no heparin. Streptokinase (SK) was associated with a nonsignificant (NS) increase in non-fatal reinfarction (3.9% SK vs 2.9% placebo) and decrease in mortality (7.5% vs 9.7% in hospital plus 6.1% vs 8.7% after discharge). After SK, there were significantly fewer strokes (0.5% vs 2.4%; 2P less than 0.05), but significantly more minor adverse events (e.g. hypotension and bradycardia, allergies, bruises or minor bleeds, nausea). Aspirin was associated with fewer non-fatal reinfarctions (3.2% aspirin vs 3.9% placebo; NS), deaths (in hospital: 6.1% vs 10.5%; 2P less than 0.05, and after discharge: 7.0% vs 6.9%; NS), and strokes (0.3% vs 2.0%; NS). Heparin was associated with a decrease in reinfarction (2.2% heparin vs 4.9% no heparin; NS), though not in mortality (in hospital: 8.0% vs 8.5%; NS, and after discharge: 7.0% vs 6.9%; NS), and with a trend towards more strokes (1.6% vs 0.7%; NS) and more bruising and bleeding (14% vs 12%; NS). To assess more reliably the effects of aspirin and of this SK regimen on mortality, about 400 hospitals worldwide are now collaborating in a large (about 20,000 patients planned) randomized trial (ISIS-2), for which the present study was a pilot.

Fifty ASA physical status class I or II patients undergoing outpatient D & C (dilatation and curettage of the uterus) were studied. Patients were divided into two groups in a random double-blind manner and given either a fentanyl bolus 0.7 microgram X kg-1 followed by continuous fentanyl infusion of 0-50 micrograms X min-1 or sufentanil bolus 0.1 microgram X kg-1 followed by continuous sufentanil infusion of 0-7 micrograms X min-1 as an adjuvant to thiopentone, nitrous oxide: oxygen anaesthesia. Patients were followed throughout the recovery process with respect to level of consciousness, nausea, vomiting, pain, and discharge time. Groups were equal with respect to awakening and discharge time. The incidence of nausea (p less than 0.05) and pain requiring analgesics (p less than 0.05) were less in the sufentanil group. It is concluded that the technique of continuous sufentanil infusion was superior to fentanyl in healthy outpatients undergoing D & C.
