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.

Temazepam 0.5, 1.0 and 1.5 mg kg-1 in an elixir formulation (Euhypnos Elixir), was compared with trimeprazine tartrate 3 mg kg-1 in a syrup (Vallergan Forte Syrup), as premedication in 220 children (ASA grade I) undergoing tonsillectomy and associated procedures. Each patient was randomly allocated to one of the four treatments. The administration was blind to the observers in theatre, recovery room and postoperative ward, who assessed each patient according to a total of 14 criteria. A modelling technique allowed account to be taken of the effects of concomitant variables (e.g. age and duration of anaesthesia) where appropriate. No statistically significant difference was found between the efficacy of the treatments. The only statistically significant differences were that temazepam was associated with more ectopic beats under anaesthesia (P = 0.03 or 0.002, depending on the test applied), more postoperative vomiting (P = 0.04) and more postoperative restlessness (P less than 0.0001).

To evaluate nasally administered sufentanil, 1.5-4.5 micrograms/kg, for pre-induction (i.e., pre-medication/induction) of anesthesia in pediatric patients, the authors studied ASA PS 1 or 2 patients scheduled for elective surgery. Eighty children, ages 6 months to 7 yr, were randomized to receive sufentanil (1.5, 3.0, or 4.5 micrograms/kg) or placebo (normal saline, 0.03 ml/kg) nasally over 15-20 s. Induction of anesthesia was completed with 5% halothane and O2 via facemask. After tracheal intubation, anesthesia was maintained with N2O (60-70%) and halothane, as clinically indicated. A blinded observer remained with the child from prior to drug administration until discharge from the recovery room. Patients given sufentanil were more likely to separate willingly from their parents and be judged as calm at or before 10 min compared to those given saline. Ventilatory compliance during induction of anesthesia decreased markedly in 25% of subjects given sufentanil, 4.5 micrograms/kg. Subjects given sufentanil moved or coughed less during tracheal intubation and required less halothane compared to those given placebo. During recovery, patients given sufentanil cried less and fewer needed analgesics; recovery times were similar for all groups. However, patients given sufentanil, 4.5 micrograms/kg, had a higher incidence of vomiting in the recovery room and during the first postoperative day. The authors conclude that nasally administered sufentanil, 1.5 or 3.0 micrograms/kg, facilitates separation of children from parents, has minimal side effects, may improve intubating conditions, and can provide postoperative analgesia.

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.

Since transdermal scopolamine (TS) seems effective against seasickness, we compared its antiemetic effect with intravenous droperidol (DHBP), our routine antidote for postoperative emesis. Ninety-six female patients (ASA I-II) scheduled for short-stay surgery were randomly allocated to three study groups after giving their informed consent. The three groups were as follows: TS adhesive, delivering 140 micrograms initially and 5 micrograms/h thereafter + placebo 0.5 ml i.v. 5 min before the end of surgery; transdermal placebo adhesive preoperatively + DHBP 0.5 ml (1.25 mg) i.v. 5 min before the end of surgery; transdermal placebo + 0.5 ml placebo i.v. as indicated above. Oxycodone i.m. and glycopyrrolate i.v. were given for premedication together with the test adhesive. Anaesthesia was induced with thiopental and maintained with nitrous oxide and oxygen, enflurane, vecuronium and fentanyl. Neostigmine and glycopyrrolate were administered for reversal. In the recovery room no differences in nausea or vomiting were observed between the groups. Sedation was significantly more marked (P less than 0.15-0.0001) after DHBP than after either TS or the given DHBP and 6% of those given the placebo (P less than 0.05). During the following 24 h nausea was reported more by the placebo patients (25) than by those on TS (20) or DHBP (15) (P less than 0.05). However, actual vomiting on the ward did not differ between the groups. Visual disturbances were more frequent after TS (P less than 0.01). We conclude that prophylactic transdermal scopolamine does not diminish postoperative emetic sequelae.

The efficacy and tolerance of flumazenil were assessed in a double-blind randomized multicentre trial on 120 ASA I or II patients aged 40.3 +/- 13.9 years. They were anaesthetized with flunitrazepam (25.1 +/- 10.5 micrograms.kg-1.h-1), fentanyl (4.4 +/- 1.9 micrograms.kg-1.h-1) and either vecuronium or pancuronium; residual neuromuscular blockade was antagonized at the end of surgery. 61 patients received flumazenil and 59 a placebo. Sedation comprehension and temporo-spatial orientation were scored at 0, 5, 15, 30, 60, 120 and 240 min after the administration of flumazenil or placebo. Local and general tolerances were evaluated 1 h and 24 h after administration. At the 24th h, the observer's assessment of consciousness, pain, respiration, coughing and vomiting were noted, as well as his identification, or not, of flumazenil or the placebo and their efficacy. Both groups were statistically homogeneous and comparable. Significant and marked efficacy was noted between the 5th and 30th min. There was no difference, at 24 h, between the flumazenil and placebo groups. In most cases, flumazenil was identified by the observer and its efficacy felt to be excellent. No major untoward effect of flumazenil was noted; however a mild and short lasting anxiety occurred in three patients. Tolerance was deemed to be excellent.

In a preliminary pilot study, the effect of disoprivan for sedation during regional anesthesia was investigated. In 15 patients (ASA I or II), lumbar epidural anesthesia with bupivacaine 0.75% was performed at L 3/4. For premedication morphine or pethidine combined with scopolamine was given. After injection of the local anesthetic, a 30-min period was allowed for establishing the physiological side effects of epidural blockade, to present any further changes in circulatory and/or cardiac function. Disoprivan (1 mg/kg body weight) was injected i.v. followed by continuous disoprivan infusion. Three groups of 5 patients each were given 1, 1.5, or 2 mg/kg per hour disoprivan. Changes in heart rate, blood pressure, and respiratory rate were studied. Recovery time and personal assessment of sleep were registered. Side-effects of clinical relevance from the cardiovascular and pulmonary systems were also registered. A dose-dependent upper airway obstruction that could easily be managed by an oral or nasal airway was seen in 9 of 15 patients. Eight patients had postoperative nausea or vomiting; 9 complained of pain during the bolus injection that they could not remember postoperatively. All patients described their sleep as pleasant. Recovery time from sleep was between 1 and 12 min. All changes from normal values increased in percentage with increasing disoprivan dosage. Disoprivan (1 or 1.5 mg/kg per hour) seems to be excellent for sedation during regional anesthesia and is perhaps even superior to other available drugs.

A series of 90 ASA class 1 or 2 young adult female out-patients, randomly assigned to four groups, were treated with placebo (saline solution), alizapride 50 mg, alizapride 100 mg or alizapride 200 mg. The incidence of postoperative nausea and vomiting has been estimated. The incidence of nausea and vomiting was lower with the alizapride-treated patients, while, contrary to the experience with other antiemetics, prolonged recovery was not observed. The incidence of vomiting in the placebo-group was twice as high as in the alizapride-groups. Of the placebo-treated patients, 20 percent requested further antiemetic medication within four hours while none of the alizapride-treated patients needed this. Alizapride 100 to 200 mg intravenously is efficacious in the prevention of postoperative nausea and vomiting.

Patient-controlled analgesia (PCA) was studied during the early postoperative period. Subjects were 40 ASA I-III patients recovering from elective major and minor surgery. Buprenorphine doses of 40 micrograms each were available whenever the patients felt pain relief necessary, and were delivered by a microprocessor-controlled injection pump (On-Demand Analgesia Computer). The hourly maximum dose was set at 320 micrograms with a lockout time of 1 minute. A continuous low-dose buprenorphine infusion (5 micrograms/h) was additionally administered in order to prevent catheter obstruction. The duration of the PCA period was 16.9 +/- 5.1 h (mean +/- SD). During this time, 16.1 +/- 11.3 demands per patient were recorded resulting in individual buprenorphine consumptions of 0.63 +/- 0.59 micrograms/kg/h. More buprenorphine was needed following abdominal surgery compared with orthopedic patients, although pain relief was found slightly less in the former group. Buprenorphine consumption was significantly higher in female than in male patients. Overall efficacy and patient acceptance proved to be excellent. The effectiveness of PCA was judged superior by about 93% of patients when compared with previously experienced postoperative analgesia. Side-effects (sweating, nausea, emesis) occurred in about 10% of cases but were usually of minor intensity. No circulatory or respiratory problems were observed during the PCA period.

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 (each 20 having undergone abdominal or orthopaedic operations). Pentazocine bolusses of each 8 mg were available via a hand-button whenever the patients felt pain relief necessary, and delivered by a microprocessor-controlled injection pump (On-Demand Analgesia Computer, ODAC). Hourly maximum dose was set to 60 mg with a pump refractory time of 1 min between valid demands. A continuous low-dose pentazocine infusion (1 mg/h) was additionally administered in order to prevent catheter obstruction. Duration of the PCA period was 20.3 +/- 5.9 h (mean, standard deviation). During this time, 20.0 +/- 12.7 demands per patient were recorded resulting in mean pentazocine consumption of 135.6 +/- 81.4 micrograms/kg/h. Self-administration was characterized by considerable intra- and interindividual variability. There were no statistically significant differences with regard of pentazocine consumption or pain relief between abdominal and orthopaedic patients, nor could any be demonstrated between the sexes. Similarly, no clear differences were found after various anaesthetic techniques (neuroleptanalgesia, halothane or spinal anaesthesia). Over-all efficacy and patient acceptance proved to be excellent. Effectiveness of PCA was judged superior by about 68% of patients when compared with previously experienced conventional postoperative analgesia. Side effects (nausea, emesis, sweating) occurred in about 10-18% but were usually of minor intensity. Circulatory or respiratory problems were not observed during the PCA period. Patient-controlled analgesia is discussed as a promising concept for the treatment of acute pain and clinical pain research.
