In a randomized, double-blind, placebo-controlled study designed to assess the post-operative analgesic efficacy and cost-effectiveness of ketorolac and diclofenac 60 ASA I and II patients undergoing laparoscopic cholecystectomy were studied. Prior to concluding the operative procedure, an injection (i.m.) of an equal volume of either saline 3 mL, ketorolac 60 mg, or diclofenac 75 mg was administered. All patients received intravenous morphine via a patient-controlled analgesia device (PCA). Post-operative pain intensity was assessed hourly for 4 h, by recording visual analogue score (VAS) for pain, PCA demands and actual morphine administered. PCA demands (mean +/- SD) were greater in the saline treatment group (115 +/- 90) when compared with both the ketorolac (42 +/- 44) and diclofenac groups (74 +/- 77). Furthermore, the saline treatment group received significantly (P < 0.05) more PCA morphine compared with both the ketorolac and diclofenac groups (12.2 mg +/- 5.0 vs. 8.6 mg +/- 5.2 vs. 8.9 mg +/- 4.8). Improved pain scores were demonstrated in both the ketorolac and diclofenac groups compared with the saline group. PCA demands and post-operative morphine requirements were similar in the ketorolac and diclofenac groups. Diclofenac has the added advantage, in our institution, of being 60% less expensive than ketorolac. We conclude that both ketorolac and diclofenac are effective post-operative analgesic drugs. However, economic considerations may favour diclofenac administration.

Clonidine is an effective preanesthetic medication in children, providing a preoperative sedative effect. The analgesic properties of the drug have been well documented in adults. The current study was designed to investigate the effect of oral clonidine given preoperatively on postoperative pain in children undergoing minor surgery. In a prospective, randomized, controlled clinical trial, 90 children aged 5-12 yr undergoing elective ophthalmic, urologic, and otologic surgery received placebo (control), clonidine 2 micrograms/kg, or clonidine 4 micrograms/kg. These drugs were administered 105 min before the estimated time of induction of anesthesia and followed by treatment with oral atropine 0.03 mg/kg 60 min before anesthesia. Anesthesia was induced and maintained with halothane and nitrous oxide in oxygen. Postoperative pain was assessed by a blinded observer using an objective pain scale (OPS). Clonidine 4 micrograms/kg provided lower OPS (highest) scores during 12 h after surgery and reduced requirement for postoperative supplementary analgesic (diclofenac suppository) compared with the other two regimens. These data suggest that oral clonidine premedication (4 micrograms/kg) is a possible approach to facilitating postoperative analgesia in children undergoing minor surgery.

The analgesic and antipyretic efficacy of propacetamol is identical to paracetamol. Because the propacetamol is injectable and its side effects are uncommon and mild, it is the drug commonly used in France for postoperative pain relief. The aim of this prospective study was to compare the analgesic efficacy of propacetamol after breast surgery or thyroidectomy when it was administered either systematically or on the patients demand. After informed consent, 119 patients having undergone breast surgery or thyroidectomy, having received the same general anaesthesia and scheduled for receiving propacetamol postoperatively, were included in the study. Two groups of patients were compared, those who received propacetamol on demand (D Group) and those who received propacetamol systematically (S Group). During the first 24 hours, analgesia was evaluated on a visual analogical scale graded from 0 to 100 mm, at rest and during mobilization; the efficacy was also evaluated by the amount of additional analgesic drug injected. Side effects were also compared between the 2 treatment groups. In the 2 groups, demographic data, type of anaesthesia and type of surgery were identical. Postoperative pain relief and supplemental injection of morphine were not statistically different between the 2 groups. Propacetamol doses were statistically higher in the S group than in the D group (7.8 +/- 0.7 g and 3.9 +/- 2.3 g respectively, p < 0.05). Pain during propacetamol infusion was more frequent in the D group than in the S group (30% and 13% respectively, p < 0.05). No other adverse effects were observed during the study. Propacetamol alone is sufficient for pain relief after peripheral surgery; more than 90% of patients need no supplemental analgesic, and adverse effects are rare.

Efficacy and safety of a PCA protocol, without loading dose or background infusion, was investigated in 40 consenting patients after osteotomy of the foot. All patients had intrathecal lidocaine 5% 1.8 ml preoperatively. Postoperative pain relief was provided with morphine from a Baxter Travenol infusor with PC module. The morphine concentration was 2 mg/ml or 3 mg/ml. In order to reach the analgesic blood concentration as quickly as possible, the patients were instructed to start PCA from the very first moment pain occurred. The patients breathed room air. The nursing staff evaluated respiratory and cardiovascular parameters, pain and side effects. Although mean VAS scores were higher than 3 in the early postoperative phase, no supplementary analgesics were required. One patient had urine retention. One patient had a drop in blood pressure at the start of morphine, which was quickly restored with the administration of colloids. Oxygen saturations were lower (SpO2 < 95%) the first hours postoperatively, especially at the first assessment where no morphine was administered. Pain or relative hypovolaemia could be an explanation. Dry mouth and sleepiness were the most frequently reported side-effects, followed by dizziness, vomiting and nausea. Sweating and itching were less frequently reported. The occurrence of the side effects was the highest during the first postoperative day. We conclude that even when morphine is used in PCA without loading dose or background infusion after opiate-free locoregional analgesia, close monitoring is necessary for at least 5 hours.

Sixty boys, aged 1-10 yr, undergoing orchidopexy were allocated randomly to receive one of three solutions for caudal extradural injection. Group A received 0.25% bupivacaine 1 ml kg-1 with adrenaline 5 micrograms ml-1 (1/200,000), group C received 0.25% bupivacaine 1 ml kg-1 with clonidine 2 micrograms kg-1 and group K received 0.25% bupivacaine 1 ml kg-1 with ketamine 0.5 mg kg-1. Postoperative pain was assessed using a modified objective pain score and analgesia was administered if this score exceeded 4. The median duration of caudal analgesia was 12.5 h in group K compared with 5.8 h in group C (P < 0.05) and 3.2 h in group A (P < 0.01). There were no differences between the groups in the incidence of motor block, urinary retention or postoperative sedation.

Postoperative pain may be a significant reason for delayed discharge from hospital, increased morbidity and reduced patient satisfaction with ambulatory hernia surgery. This study compared two postoperative oral analgesic protocols after day case inguinal hernia repair; 30 mg morphine sulphate (MST) and 10 mg metoclopramide every 8 h for 48 h or 75 mg diclofenac twice daily for 48 h. The pain reported in the MST group was significantly greater on both the day of operation and the first postoperative day (P < 0.05, Mann-Whitney U test). A significantly higher proportion of patients taking MST complained of nausea on the day of operation and on the 1st postoperative day (P < 0.05, chi 2). The time taken to walk, dress and leave home alone were achieved in a significantly shorter duration in patients taking diclofenac. We conclude that diclofenac provides effective analgesia, has a more acceptable side-effect profile than morphine sulphate and is the treatment of choice after ambulatory hernia surgery.

A prospective study was undertaken to compare the analgesic effect of intra-articular bupivacaine, morphine, or saline in the 24-hour period following cranial cruciate ligament repair in dogs. Thirty-six clinical patients with ruptured cranial cruciate ligaments were randomly assigned to one of three groups. After surgical stabilization, and before skin closure, an intra-articular injection was given; group one (n = 12) received 0.5% bupivacaine HCl at 0.5 mL/kg, group two (n = 12) received morphine at 0.1 mg/kg diluted with saline to a volume of 0.5 mL/kg, and group three (n = 12) received saline at 0.5 mL/kg. Heart rate, respiratory rate, mean arterial blood pressure, cumulative pain score, visual analog pain score, and pain threshold test on both stifles were recorded preoperatively and at 0 to 6 and 24 hours postoperatively. Surgeons and pain scoring investigators were unaware of the intra-articular medication given. Supplemental analgesia, if needed, was provided in the postoperative period according to subjective assessment of patient discomfort. Postoperative pain scores were lowest in the bupivacaine group and highest in the saline group. Pain threshold, measured by applying calibrated loads to the knee, was higher postoperatively in the bupivacaine group than in the saline group. Dogs in the morphine and bupivacaine groups required less supplemental analgesia than dogs in the saline group. The local provision of analgesia reduces the need for systemic drugs with potential side effects. Both intra-articular morphine and intra-articular bupivacaine provided better postoperative analgesia than intra-articular saline, with intra-articular bupivacaine showing the greatest effect.

Postoperative nausea, vomiting and pain were compared between laparoscopic cholecystectomy group and minilaparotomy-cholecystectomy group. All patients were women, and ranged in age from 20 to 60 years. The body mass index of the patients was less than 30, and duration of operation was within 120 minutes in both groups. All patients received general anesthesia combined with epidural analgesia. Morphine hydrochloride 4 mg was administered into epidural space before incision. No significant differences were found in the incident of nausea and vomiting among the two groups. Postoperative analgesic requirement of laparoscopic cholecystectomy group was significantly less than that of minilaparotomy-cholecystectomy group. No significant differences were found in the incidence of nausea and vomiting between the group which required postoperative analgesic drugs and the group which required no postoperative analgesic drugs. These results suggest that laparoscopic operation and postoperative pain do not influence the incidence of nausea and vomiting. Postoperative pain after laparoscopic cholecystectomy is less than that after minilaparotomy-cholecystectomy.

Postoperative pain after spinal surgeries is highly dependent on the number of vertebrae included in the operation and on its invasiveness, opposing two extremes, discectomies and cyphoscoliosis corrections. Opiates by intravenous route remain the reference, either continuously given in predetermined doses, or better using a patient-controlled device. Nonsteroidal and steroidal anti-inflammatory drugs are widely popular for medical approach of sciatalgia and it is quite logical to use them for reducing, even to suppress, opiates after spinal surgeries. Supported by many studies, spinal administration of analgesics (opiates, alpha 2-agonists, corticosteroids) may be of interest in pain treatment of spinal surgeries. In order to prolong locoregional analgesia, a catheter may be inserted into epidural space by caudal route or surgically, before skin closure. Morphine is the most popular agent in this indication. Also, epidural clonidine results in excellent pain relief, but is associated with hypotension and marked sedation. In discectomy, injection of dexamethasone into the operative field has been proposed. Whatever the technique used, early diagnosis of neurological complications of spinal surgery should be not ruled out by postoperative analgesia.

Postoperative pain after shoulder surgery is known to be intense and requires usually opioid administration. The recent use of regional anaesthesia for this type of surgery has contributed to the relief of acute postoperative pain occurring in the recovery room since the analgesic effects of block persist for several hours after surgery depending upon the selected drug. Moreover, the development of less invasive surgery (arthroscopy) and experience with regional blocks have permitted to perform minor shoulder surgery on an outpatient basis. For minor surgery, regional anaesthesia associated to a light sedation is sufficient. However, for more invasive surgery, regional anaesthesia should be associated to a light general anaesthesia as well as the insertion of a supraclavicular catheter for postoperative analgesia. A diaphragmatic paresis secondary to a blockade of the phrenic nerve is constant radiologically after interscalenic block but remains symptomless. However, in case of severe preoperative chronic respiratory insufficiency, decompensation may occur rapidly after performance of the interscalenic block.
