Postoperative pain was assessed in patients undergoing inguinal hernia repair. Ten patients received lidocaine aerosol in the surgical wound before skin closure, ten patients received placebo aerosol devoid of lidocaine, and ten patients were untreated. The lidocaine-treated group had significantly lower pain scores and meperidine requirements during the first postoperative day compared to the control groups. During the second day after surgery, these variables did not differ between groups. Wound anesthesia, assessed by palpation of the wound 24 h after surgery by a blinded investigator, was significantly more pronounced in the group treated with lidocaine aerosol than in the control groups. Similarly, in patients undergoing bilateral herniorraphy, wound pain following palpation was significantly reduced on the lidocaine-treated side compared to the untreated side. Patients in the group receiving lidocaine aerosol indicated less pain in connection with mobilization than untreated patients, but not compared to patients treated with placebo aerosol. Plasma substance P (SP) and beta-endorphin (BE) measured in lidocaine-treated patients and in untreated patients before and after drug administration showed no significant differences regarding SP, while BE was significantly increased 1 h after surgery in the untreated group. Plasma lidocaine concentrations were well below toxic levels. Results show that lidocaine aerosol used as topical anesthetic in the surgical wound is simple to use, and results in a long-lasting reduction of pain after a single administration. Moreover, postoperative mobilization is facilitated, and the requirement for postoperative analgesics is reduced. Wound healing was normal, and no adverse reactions to lidocaine were reported.

It has been suggested in various studies that the opiate agonist/antagonist nalbuphine (Nubain) provides for effective reversal of the respiratory depression after fentanyl while maintaining postoperative analgesia. We tested this hypothesis in a relatively large number of patients. The study consisted of two parts: one randomized open, the other randomized double-blind, each with 150 ASA I or II patients aged 18 to 65 years. After premedication with atropine 0.5 mg and flunitrazepam 0.5 mg, anaesthesia was induced with flunitrazepam 0.5 mg, fentanyl 0.1 mg, and etomidate 10 mg and maintained with N2O/O2, 2/1, and additional increments of 0.1 mg fentanyl as required. Relaxation for intubation and surgery was obtained with vecuronium, atracurium, or pancuronium depending on the expected duration of anesthesia. After the operation the patients were extubated and the residual effects of fentanyl antagonized with naloxone 0.05 mg or nalbuphine 10 mg or 20 mg i.v. (randomized open or double-blind). The patient data and fentanyl dosages are given in Table 1. Postoperative pain was assessed by the time interval between administration of the opiate antagonist and the requirement for the first analgesic medication. Figures 1a and b and Table 2 indicate that after nalbuphine 20 mg the first analgesic was required significantly later than after naloxone 0.05 mg (median 115 or 123 min after nalbuphine 20 mg vs 56 or 52 min after naloxone 0.05 mg; P less than 0.02). There was no significant difference between nalbuphine 10 mg and naloxone 0.05 mg. The open and double-blind studies gave virtually identical results. Sixty minutes after administration of 20 mg nalbuphine, vigilance was significantly reduced.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty children who underwent day case herniotomy received either a caudal injection of 1 ml/kg bupivacaine 0.25% or infiltration of the wound edges at the end of surgery with 0.5 ml/kg bupivacaine 0.25%, allocated at random. Postoperative pain and demeanour were assessed initially by an observer and later by use of a parental questionnaire. Wound infiltration of local anaesthetic solution provided analgesia which was comparable to that associated with caudal block, and the incidence of side effects was similar in the two groups. Wound infiltration of local anaesthetic offers a simple, safe alternative to caudal block for provision of postoperative analgesia in this group of patients.

Postoperative pain is a major problem following surgery in the ambulatory child. A study was undertaken to test the effect of intraoperative bupivacaine on postoperative pain in children undergoing outpatient hernia repair. Ninety-nine children aged 1 to 7 years underwent outpatient inguinal herniorrhaphy under general anesthesia. Each was randomly assigned to receive bupivacaine (group 1) or saline (group 2), infiltrating the ilioinguinal and iliohypogastric nerves. Drug administration and patient evaluation were double-blinded. The groups were similar with respect to age, sex, side of procedure, and length of operation. In the immediate postoperative period, 17 group 1 patients required analgesics compared with 39 in group 2 (P less than .01); total codeine dosage was lower in group 1 (4.0 +/- 7.1 mg v 11.8 +/- 10.5 mg, P less than .05). Activity level 45 minutes after surgery (using a standardized scale) was greater in group 1 (P less than .05). Acetaminophen requirements at home were lower in group 1 on the day of surgery (3.1 +/- 4.3 mL v 5.7 +/- 7.4 mL, P less than .05) and over the following 48 hours (1.5 +/- 3.4 mL v 4.9 +/- 10.7 mL, P less than .05). Activity level at home on the day of surgery did not differ significantly between groups, but activity level over the following 48 hours was higher in group 1 (P less than .05). The two groups were similar with respect to all other parameters. We conclude that intraoperative bupivacaine decreases post-operative pain and analgesic use, and promotes early ambulation in children undergoing hernia repair.

Analgesia is an important problem in myasthenia gravis patients who have undergone transsternal thymectomy. Postoperative pain interferes with pulmonary function, which is already limited by the disease. The choice of medication is restricted because many analgesics are synergic to the myasthenia gravis syndrome and detrimental to the patient. Three patients with severe myasthenia gravis are presented who had undergone transsternal thymectomy with good postoperative results. They received high thoracal epidural anesthesia (C7-Th1/Th1-Th2/Th2-Th3) with a solution of bupivacaine and morphine (20 ml 0.25% bupivacaine with 10% morphine). The patients were extubated in the first 48 hours and monitoring of respiratory function (CV2, PO2, PCO2) showed satisfactory values. With this type of analgesia we obtained early mobilization and good patient cooperation. Although limited this favourable experience confirms that high thoracal epidural anesthesia is a sure technique which allows rapid weaning from the ventilator and maximum comfort for the patient. It avoids the use of other medication or analgesics which are contraindicated in these patients.

Postoperative pain was treated by epidural administration of 30 to 50 mg pethidine (5 mg X ml-1) in a group of 36 patients who had undergone retropubic prostatectomy. Surgery was carried out under epidural anaesthesia with lidocaine. Pain was assessed by means of the visual analogue scale. A general study of the effects of injections and reinjections showed that analgesia thus obtained was excellent at the first hour after injection and lasted 3 to 5 h. The effect of the first postoperative injection on spontaneous pain was studied in 14 patients. Statistical analysis (Wilcoxon test) demonstrated that the fall in pain score was significant at the first and third hours after injection, but not significant at the fifth hour. The analgesia to that pain produced by coughing was studied in 11 patients. There was a significant decrease in pain at the first hour after injection; differences in pain scores at the third hour were not significant. No noticeable side-effect was observed. It was concluded that low doses of epidural pethidine were efficient on postoperative pelvic abdominal pain, but that doses should be increased if painless coughing was required.

Twenty patients undergoing major abdominal surgery were allocated randomly to receive either general anaesthesia with low-dose fentanyl plus intermittent systemic morphine for postoperative pain or the same general anaesthetic plus extradural analgesia during and following surgery (local anaesthetics from before skin incision until 24 h after skin incision plus extradural morphine 4 mg every 12 h from 3 h to 72 h after skin incision). Postoperative pain scores were lower (P less than 0.05) in the group receiving extradural analgesia, but this regimen failed to prevent the increase in the urinary excretion of cortisol, adrenaline, noradrenaline and nitrogen both on separate days and on cumulative measurements over 4 days. Pain scores did not correlate to urinary excretion of the various endocrine-metabolic indices either on separate days or over the cumulative 4-day period. It is concluded that the relief of pain per se has no major influence on the catabolic response to abdominal surgery.

In a randomized cross-over study on sedation in outpatient oral surgery, subcutaneous administration of morphine-scopolamine was compared with rectal administration of diazepam. The mean dose of morphine was 0.13 mg kg-1 (range 0.13-0.24) and of diazepam 0.57 mg kg-1 (range 0.50-0.71). Apprehension, the determining factor for patients' preference for sedation method, the recovery from sedation and the postoperative course were studied. Both methods produced the desired effects. For diazepam, the effect was scored higher by the patient than the nurse observer and for morphine-scopolamine the opposite was found. Postoperative pain and patients' preference for sedation did not differ between the methods and the determining factor for the patients' preference for sedation method was the experience of stronger tranquilization. Side-effects such as prolonged recovery, nausea, dizziness, and dysphoria were frequent during the postoperative course after the morphine-scopolamine sedation but were not seen during diazepam sedation. Thus, rectal administration of diazepam should be preferred to morphine and scopolamine for sedation in minor oral surgery performed under local anesthesia.

A hundred patients scheduled for elective abdominal surgery were randomized to either general anaesthesia (low-dose fentanyl) and systemic morphine for postoperative pain or combined general anaesthesia and epidural analgesia with etidocaine 1.5% intraoperatively (T4-S5) and bupivacaine 0.5% 5 ml/4 h for 24 h and morphine 4 mg/12 h for 72 h. Postoperative pain was better controlled by the epidural regimen (P less than 0.0001). We found no significant reduction in postoperative mortality (6% to 2%), pneumonia (28% to 20%), cardiac dysrhythmia (10% to 5%) and wound complications (14% to 11%) by the epidural analgesic regimen. The incidence of deep venous thrombosis (125I-fibrinogen scan) was 32% after general anaesthesia and low-dose heparin and 34% after epidural analgesia with no prophylactic antithrombotic treatment (P greater than 0.9). Postoperative weight loss and decrease in serum-albumin and serum-transferrin, as well as the reduction in haemoglobin and the need for postoperative transfusions, were similar in the two groups. Convalescence, as assessed by postoperative fatigue, restoration of bowel function (flatus, bowel movement and food intake) and the time until the patients were self-aided at their preoperative level, was not reduced by epidural analgesia. Since 50% of the patients in each group suffered from one or more of the above-mentioned postoperative complications, this epidural regimen was not effective in reducing postoperative morbidity after major abdominal surgery despite the achievement of adequate pain relief.

Epidural morphine infusion is an effective and relatively safe route for postoperative analgesia. Lanz , Theiss , Reiss , and Sommer performed research supporting the use of epidural morphine. Following lumbar epidural anesthesia for orthopedic operations, 174 patients underwent the following study. At the end of surgery under double-blind conditions, 57 patients in group 1 received 0.1 mg/kg of morphine in 15 ml of normal saline epidurally and normal saline 0.01 ml/kg intramuscularly. Patients in group 2 (57 patients) received intramuscular morphine 0.1 mg/kg and normal saline 15 ml epidurally. Patients in group 3 (60 patients) received normal saline 15 ml epidurally and normal saline 0.01 ml/kg intramuscularly. Postoperative pain was less frequent, of shorter duration, and less severe following epidural morphine (group 1). Sympathetic block was only partial; patients still noticed pressure due to a dressing or cast. There was no motor blockade and active mobilization occurred earlier. Following epidural morphine, alertness was heightened, patients were more cooperative, and respiratory depression and postoperative pneumonia were less than after systemic administration of narcotics.(ABSTRACT TRUNCATED AT 250 WORDS)
