Postoperative pain is commonly treated with significant doses of narcotics, occasionally resulting in side effects including nausea, pruritus, and respiratory depression. One potential advantage of regional anesthesia is profound postoperative analgesia that reduces exposure to potent narcotics. To evaluate the efficacy of two long-acting local anesthetics, bupivacaine and etidocaine, in providing pain relief after major shoulder surgery, we randomized 20 patients to receive either bupivacaine or etidocaine for brachial plexus block as the primary anesthetic for shoulder surgery. Surgeons, patients, and the acute pain service were blinded as to drug selection. After the patient was sedated, an interscalene block was placed with the use of a nerve stimulator to facilitate proper needle placement. Forty milliliters of either 0.5% bupivacaine or 0.75% etidocaine containing 5 micrograms/mL epinephrine was injected into the brachial plexus sheath. An additional 8 mL of local anesthetic was administered for superficial cervical plexus blockade. Intraoperative sedation was accomplished with an intravenous infusion of methohexital as needed. After surgery, patients received a standard patient-controlled analgesia protocol providing incremental doses of morphine. The degree of postoperative analgesia resulting from residual local anesthetic effect was expressed as the time until first morphine requirement and the total dose of morphine required during the first 24 hours postoperatively. We found no statistically significant intergroup differences either in time of initial use of morphine or in the total dose of morphine required in the first 24 hours. Both etidocaine and bupivacaine provide prolonged analgesia after major shoulder surgery when injected into the brachial plexus. Bupivacaine, however, possesses significant cardiotoxicity and has a relatively delayed onset in peripheral neural blockade. Etidocaine is less cardiotoxic and also has a more rapid onset of effect. Thus etidocaine may be a preferable agent for interscalene block for major shoulder surgery.

The postoperative analgesia afforded after colonic surgery by IV opioid, clonidine and lignocaine given intra- and postoperatively was evaluated. In a double-blind randomised trial, 80 male patients scheduled for colonic resection under general anaesthesia received fentanyl 5 micrograms.kg-1 at induction and another 4 micrograms.kg-1 before skin incision (group A) or fentanyl (same dose) plus clonidine 4 micrograms.kg-1 in 20 min + 2 micrograms.kg-1.h-1 (group B, C) or fentanyl plus clonidine (same dosage) plus lignocaine 2 mg.kg-1 before skin incision, repeated before peritoneal incision and retractor placement (group D). In the four groups, intraoperative boluses of fentanyl 2 micrograms.kg-1 were given in response to the painful stimulation of the procedure. Postoperative pain was managed with PCA delivering 2 mg morphine per request in group A, 1.5 mg morphine in group B, 1.5 mg morphine + 15 micrograms clonidine in group C and 1.2 mg morphine + 15 micrograms clonidine + 23 mg lignocaine in group D. Postoperative analgesia was assessed by recording the analgesic demands (met and unmet) and the dose of morphine delivered at 6, 12, 18, 24, 36 hours. Side-effects, pain and sedation analogue scores were also recorded. Analgesic demands and delivered morphine dose were reduced, at any time interval considered, in groups B, C, D, compared with A (P < 0.001). No differences were noted between the group B, C, D. Pain analogue scores were better in groups B, C, D compared with group A (P < 0.001). Sedation and side-effects were not increased in groups B, C, D.(ABSTRACT TRUNCATED AT 250 WORDS)

The study was conducted on 20 infants scheduled for cleft lip repair surgery. Ten were randomly allocated to receive bilateral infra-orbital local anaesthetic nerve blocks at the conclusion of surgery with the other 10 receiving bilateral 'sham' blocks as controls. Postoperative pain relief was assessed using a pain assessment scoring system and by monitoring arterial blood pressure, heart rate and respiratory rate. The mean pain assessment score was significantly higher (i.e. better) (p < 0.05) in the infants receiving the local anaesthetic block. There were no significant statistical or clinical differences in the physiological measurements between the two groups. The infants receiving the block required less analgesia in the postoperative period. The results suggest that infra-orbital nerve block is a simple and effective means of achieving postoperative analgesia after cleft lip repair surgery in infants.

We have studied the effects of electroacupuncture at classical acupuncture points, applied before and during surgery in patients undergoing hysterectomy, on postoperative pain and metabolic stress responses in a prospective, randomized and patient-blinded manner. Fifty otherwise healthy women were allocated randomly to receive or not receive electroacupuncture. Electroacupuncture was begun 20 min before skin incision and continued to the end of surgery. All patients received similar general anaesthesia and all received patient-controlled analgesia (PCA) after operation. Postoperative pain in the two groups was evaluated by recording analgesic requirements by PCA and by pain-rating performed by patients and nursing staff. There were no significant differences between the two groups in postoperative analgesic requirements, pain-rating or metabolic stress responses.

A prospective study has been performed of factors influencing postoperative pain in a cohort of children undergoing dental extractions under general anaesthesia. Postoperative pain was assessed immediately after recovery from anaesthesia and also by using a visual linear analogue scale which was completed by the parent hourly for the first 10 hours and then at 24 hours. Analgesic use was also recorded. The most significant factor influencing postoperative pain was the relationship of the accompanying adult to the child; children attending with their mothers were more likely to complain of postoperative pain (P < 0.05). The results also suggested that the age of the patient and the extraction of primary rather than permanent teeth were influencing factors, although they did not reach statistical significance. Pain was reported by 57.5% of the children immediately after treatment. It would seem that the greatest need for postoperative analgesia is immediately after the dental procedure, especially in young children undergoing multiple extractions.

Sixty five children aged from 1-10 years who underwent herniotomy, cystolithotomy or orchidopexy received either buprenorphine 4 micrograms kg-1 (n = 33) or morphine 50 micrograms kg-1 (n = 32) by the caudal epidural route; each thus received 0.5 ml kg-1 body weight. General anaesthesia was given for surgery. Post-operative pain and behaviour were assessed by an independent observer at 1, 4, 8, 16 and 24 h post-operatively. Caudal morphine and buprenorphine were equally effective for post-operative analgesia in children, but buprenorphine was better because of its longer duration of action and lower incidence of side effects.

A randomised double-blind study was carried out on 60 patients undergoing elective lumbar discectomy. Patients in the study group (n = 30) received an injection of 10 ml of 0.5% bupivacaine into the wound; the control group (n = 30) received none. Postoperative pain was measured by a visual analogue pain scale and by the amount of morphine administered by a patient-controlled analgesia system. Patients in the study group had lower pain scores, used less morphine, waited longer until their first demand for analgesia and reported their postoperative pain to be less severe.

A randomized, double-blind, controlled study was conducted in patients undergoing elective knee arthroscopy to assess the analgesic effect of intraarticular morphine and bupivacaine, alone and in combination. Patients in group 1 (n = 10) received 5 mg of morphine in 25 mL of saline; patients in group 2 (n = 10) received 25 mL of 0.25% bupivacaine (62.5 mg); patients in group 3 (n = 10) received a combination of 5 mg of morphine and 62.5 mg of bupivacaine in 25 mL dilution; and patients in group 4 (n = 10) received 25 mL of saline. All the drugs were injected intraarticularly. Postoperative pain was assessed using the visual analogue scale at 1, 2, 4, 8, and 24 h after the intraarticular injection. The need for supplemental analgesia was recorded. Results showed that there was no significant difference in the pain scores or analgesic requirements between groups 1 and 3. Patients in groups 1 and 3 had significantly lower pain scores than those in groups 2 and 4. These low pain scores were associated with lower requirements of supplementary analgesics. The patients in group 4 showed the highest pain scores and analgesic requirements. We conclude that intraarticular morphine significantly reduces postoperative pain following knee arthroscopy and that there is no advantage of combining bupivacaine with morphine.
