Epidural morphine is used for postcesarean analgesia, and nonsteroidal antiinflammatory drugs are frequently administered to relieve uterine cramps after vaginal delivery. To assess the efficacy of a combination of low-dose epidural morphine and intramuscular diclofenac sodium in postcesarean analgesia, a double-blind, randomized study was conducted. Epidural anesthesia was given to 120 parturients who were randomly allocated into four treatment groups: group A received normal saline solution, 10 mL epidurally and 3 mL intramuscularly (IM); group B received 10 mL of epidural saline solution and 75 mg (3 mL) of diclofenac IM; group C received 2 mg of morphine in 10 mL of epidural saline solution and 3 mL of saline solution IM; and group D received 2 mg of morphine in 10 mL of epidural saline solution and 75 mg of diclofenac IM. Epidural injections were given after delivery of the placenta, and IM injections were given on arrival in the recovery room. Verbal analogue pain scores were recorded at 2, 4, 8, 12, 18, and 24 h after epidural injection. Subjective scores of overall pain relief were also recorded at 24 h. Results showed that scores of overall pain relief were significantly better in group D compared with group A, B, or C (P less than 0.05). Groups A and B required more supplemental meperidine than groups C and D. None of the subjects in group D requested supplemental analgesia. Compared with the other three groups, group D experienced a better analgesic effect for both wound pain and uterine cramping pain from 4 to 18 h (P less than 0.05). Incidence of nausea or vomiting, or both, and pruritus occurred more frequently in groups C and D compared with group A or B (P less than 0.05). No bradypnea was observed during the study period. Diclofenac alone was not effective in postcesarean analgesia.(ABSTRACT TRUNCATED AT 250 WORDS)

We have studied the efficacy of a continuous i.v. infusion of diclofenac 2 mg kg-1/24 h given for 2 days after major thoracic surgery in 30 patients in a double-blind, placebo-controlled, parallel-group design. The patients were able to obtain additional pain relief as on demand morphine boluses. In the diclofenac group, the consumption of morphine was reduced by 60% during the first and by 76% during the second day after operation compared with the control group. Overall, analgesia was also superior in the diclofenac group. Arterial oxygenation was significantly greater and the arterial PCO2 increased less during the first day after operation in the diclofenac group compared with the control group. Diclofenac had no significant effect compared with placebo on blood loss or on any bleeding or platelet test. Urine output was significantly less during the first day after operation in the diclofenac group compared with the control group, but was normal on the second day after operation; plasma creatinine concentrations were unchanged. I.v. diclofenac infusion combined with opioids delivered via a patient-controlled analgesia device seems a valuable method of pain relief after thoracic surgery in patients in whom more invasive techniques, such as extradural local anaesthetics and opioids, cannot be used. However, non-steroidal anti-inflammatory drugs should be used cautiously, if at all, in patients who are at risk of acute renal failure.

1. Vomiting and restlessness following ENT and eye surgery are undesirable, and may be related to the emetic and analgesic effects of any analgesic given to augment anaesthesia during surgery. 2. To rationalise the choice of analgesic for routine ENT surgery we examined the intraoperative, recovery and postoperative effects following the administration of either buprenorphine (3.0 to 4.5 micrograms kg-1), diclofenac (1 mg kg-1), fentanyl (1.5 to 2.0 micrograms kg-1), morphine (0.1 to 0.15 mg kg-1), nalbuphine (0.1 to 0.15 mg kg-1), pethidine (1.0 to 1.5 mg kg-1) or saline (as control) given with the induction of anaesthesia in 374 patients. A standardised anaesthetic technique with controlled ventilation using 0.6-0.8% isoflurane in nitrous oxide and oxygen was employed. The study population constituted 7 similar groups of patients. 3. Intraoperatively, their effects on heart rate and blood pressure, airway pressure and intraocular pressure, were similar. This implies, most surprisingly, that neither their analgesic nor their histamine releasing effects were clinically evident during surgery. By prolonging the time to extubation at the end of anaesthesia, only buprenorphine, fentanyl, morphine and pethidine provided evidence of intraoperative respiratory depression. 4. Postoperatively, buprenorphine was associated with severe respiratory depression, prolonged somnolence, profound analgesia and the highest emesis rate. Diclofenac exhibited no sedative, analgesic, analgesic sparing, emetic or antipyretic effects. Fentanyl provided no sedative or analgesic effects, but was mildly emetic. Morphine provided poor sedation and analgesia, delayed the requirement for re-medication and was highly emetic. Nalbuphine and pethidine produced sedation with analgesia during recovery, a prolonged time to re-medication and a mild emetic effect. None provided evidence, from analysis of postoperative re-medication times and analgesic consumption, of any pre-emptive analgesic effect. 5. We conclude that nalbuphine (mean dose 0.13 mg kg-1) and pethidine (mean dose 1.35 mg kg-1), given individually as a single i.v. bolus during induction of anaesthesia, are the most efficacious analgesics for routine in-patient ENT surgery.

The pharmacodynamics and pharmacokinetics of 75 mg resin-bound diclofenac (resinate) were compared with enteric-coated tablets containing 75 mg of diclofenac in a double-blind randomized crossover trial in 16 patients suffering from rheumatoid arthritis. Diclofenac was significantly faster absorbed from the resinate than from the enteric coated formulation (tlag = 0.454 h vs. 0.998 h, tmax = 1.41 h vs. 2.56 h) and reached lower peak concentrations (Cmax = 1.64 micrograms/ml vs. 2.59 micrograms/ml). No significant differences were found concerning the area under the plasma level-time curves and the mean residence times. Smaller variances were found for the tmax and the mean residence times in the group treated with diclofenac resinate. Onset and duration of analgesia, as assessed by visual analogue scales were similar in both treatment groups, but did not correlate with the plasma concentrations. Four patients experienced adverse effects including gastric pain, transaminase increases, proteinuria and plasma creatinin increase. No uncommon adverse effects were observed with the new preparation.

Forty patients who underwent upper or mid-abdominal surgery were randomly allocated to receive a post-operative epidural infusion of 0.083 mg ml-1 of diamorphine in either 0.167% bupivacaine or 0.9% NaCl solution. The nursing staff, who were unaware of which solution was being infused, managed the patients' pain according to a standardized scheme. They adjusted the epidural infusion rates to 3, 5 or 7 ml h-1 according to the patient's hourly reports of pain on a four point verbal rating scale (none, mild, moderate or severe), aiming to use the lowest allowed infusion rate to prevent or reduce any pain that was more than mild. Additional analgesia was given as diclofenac 75 mg intramuscularly if the patients report moderate pain while on the highest infusion rate. The nurses were instructed to summon anaesthetic help if pain relief was still unsatisfactory after diclofenac, but this was never necessary. Diclofenac was needed by six patients receiving diamorphine in saline and one receiving diamorphine in bupivacaine (P < 0.05). The range of average hourly epidural infusion rates was constrained by design to between 3 and 7 ml h-1 but the median of these values was 5 ml h-1 in the diamorphine-saline group and 3.35 ml h-1 in the diamorphine-bupivacaine group (P < 0.02). In patients receiving diamorphine in saline, a median of 6 (range 0-16) of the 24 h reports were of more than mild pain, whereas in the diamorphine-bupivacaine group, the corresponding figures were 2 (range 0-13) (P < 0.02)).(ABSTRACT TRUNCATED AT 250 WORDS)

Nonsteroidal anti-inflammatory drugs (NSAIDs) produce potent analgesic, antipyretic, and anti-inflammatory effects. We studied postoperative pain in 97 consecutive patients having photorefractive keratectomy (PRK) by an excimer laser with different topical NSAID protocols. Treatment with topical homatropine hydrobromide, either diclofenac sodium (Voltaren Ophthalmic) or ketorolac tromethamine (Acular), and a soft contact lens was most effective in achieving post-PRK analgesia. We also studied post-PRK myopic regression in 68 consecutive patients and found that flurbiprofen sodium (Ocufen), when added to topical steroid protocols, significantly reduced myopic regression for one year postoperatively more than steroids alone or steroids and diclofenac sodium. Diclofenac, used with topical steroids, had less of an additive effect on myopic regression than did flurbiprofen. Topical NSAIDs are useful adjuncts to PRK therapy, both to eliminate postoperative pain and to control post-PRK myopic regression.

At Helsinki University Central Hospital in Finland, clinical researchers divided 169 women into two groups (group 1: diagnostic laparoscopies; group 2: laparoscopic sterilizations) as part of a study to evaluate the effect of intravenous diclofenac on postoperative pain, nausea, and recovery after outpatient gynecological laparoscopy. After induction of anesthesia (propofol infusion, total dose = about 370 mg), the patients randomly received, in a double-blind approach, either 100 mg diclofenac sodium (Voltaren, Ciba-Geigy) diluted in 10 ml saline or 10 ml saline alone. Patients in the saline group needed much more fentanyl and paracetamol for pain relief than those in the diclofenac group (47 vs. 25 mcg and 0.69 vs. 0.23 g, respectively; p 0.05). Even though a higher proportion of diclofenac patients experienced postoperative nausea and vomiting (17% vs. 6%) and thus were more likely to receive droperidol (9% vs. 2%), the differences were not statistically significant. Laparoscopic sterilization patients experienced more pain and required more pain relievers postoperatively than diagnostic laparoscopy patients. Specifically, sterilization patients receiving saline received 2.8 times more fentanyl and 1.9 times more paracetamol than diagnostic laparoscopy patients. As for diclofenac patients, these figures were 4.9 and 5.5, respectively. Sterilization patients had more nausea and vomiting than diagnostic laparoscopy patients (34% vs. 11%; p 0.001). Diclofenac did not influence the rapidity of recovery or home readiness in either group. These findings show that diclofenac significantly reduced the need for postoperative analgesia in diagnostic laparoscopy patients but not laparoscopic sterilization patients.

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.

The purpose of this study is to determine the effect of postoperative analgesia on the amount of breast feeding and infant weight gain. Thirty parturients undergoing elective cesarean section under spinal anesthesia were randomly allocated to receive postoperative pain management with (S-E group, n = 15) or without epidural bupivacaine (S group, n = 15). Epidural analgesia was performed for 3 days with a continuous epidural infusion (0.7 mL/h) of 0.25% bupivacaine. Diclofenac was available on demand in all patients. The weight of milk fed by breast and the infant weight were measured for 11 days after cesarean section. In the S-E group, the visual analog pain score after surgery was significantly lower and both the weight of milk fed by breast and the infant weight during the study were significantly more than the respective values in the S group. The S group required a larger dose of diclofenac after the operation than did the S-E group. We suggest that satisfactory postoperative pain relief with continuous epidural bupivacaine for 3 days after cesarean section improved the amount of breast feeding and the gain of infant weight.

Paravertebral analgesia is highly effective in blocking unilateral afferent input from the trunk, but its bilateral use does not appear to have been described. Eight patients undergoing major abdominal vascular surgery had pre-operative bilateral paravertebral catheters inserted. A dose of 25 ml of bupivacaine 0.5% divided between the two catheters provided the basis of an effective intra-operative analgesic regimen which was continued postoperatively by infusion of bupivacaine for 4 days. Diclofenac and morphine completed a balanced analgesic regimen which was started pre-operatively and continued for 5 and 3 days respectively. Cardiovascular stability was notable throughout surgery, even with aortic clamping and all patients were extubated at the end of surgery. Good quality analgesia was obtained as assessed by low postoperative pain scores at rest and on movement. Three patients were not admitted to the intensive care unit, where mean stays for the group was 10 h (range 0-24 h) and mean hospital stay was 10 days (range 7-14). There were no additional demands made on the nursing staff and no postoperative pain-related complications occurred. We conclude that bilateral paravertebral analgesia, as part of a balanced analgesic technique, is an alternative method of providing effective afferent blockage for major abdominal surgery.
