Effect of short-term ketorolac infusion on recovery following laparoscopic day surgery.

This study tested the hypothesis that, by the addition of parenteral ketorolac to an oral analgesic regimen for one day following laparoscopic surgery, analgesia would be improved and thus the return of normal function hastened. Seventy-two female patients were randomly assigned to receive ketorolac 10.5 mg subcutaneously at the end of surgery followed by a subcutaneous infusion of 1.75 mg/h for 24 to 36 hours, or an equivalent volume of saline. All patients were provided with codeine tablets (30 mg) for analgesia if required. For the first four postoperative days patients recorded details of pain, side-effects and discomfort on performing everyday activities. Patients who received ketorolac received significantly less fentanyl in the Recovery Ward and significantly less codeine prior to discharge than the saline group. They also took significantly fewer codeine tablets over the four-day postoperative period. Pain scores in the ketorolac group were not significantly lower than in the saline group on the first postoperative day (P = 0.052) and subsequently remained similar. Levels of discomfort on performing six common activities were similar in the two groups over the four-day postoperative period. We conclude that, despite beneficial effects during the period of ketorolac administration, there was no continuing benefit after this time other than reduced analgesic use, and no improvement in the patients' ability to perform common activities.

Lack of efficacy of propofol in the treatment of early postoperative nausea and vomiting.

The anti-nauseant efficacy of low-dose propofol was investigated in a blinded, randomized trial. Patients who complained of nausea and/or vomiting following laparoscopic gynaecological surgery and who requested antiemetic were randomly assigned to receive placebo, propofol 3 mg, propofol 9 mg or propofol 27 mg by intravenous injection. Nausea, vomiting and sedation were recorded by a blinded observer for 90 minutes following administration of the test drug, prior to discharge, and 24 hours following surgery. Rescue antiemetic (droperidol 1.0 mg i.v.) was available from 10 minutes after administration of test drug. Propofol failed to reduce nausea scores and did not reduce the incidence of vomiting. Numbers of patients receiving rescue antiemetic were similar in the four treatment groups. In the first 10 minutes following test drug administration, sedation scores were increased by propofol in a dose-related manner. We conclude that, in the dose range studied, propofol is ineffective for the treatment of nausea and vomiting occurring soon after laparoscopic gynaecological surgery.

Variable-dose patient-controlled analgesia. A preliminary report.

One size of patient-controlled analgesia demand dose does not suit all patients after surgery. We have constructed a new patient-controlled analgesia (variable-dose patient-controlled analgesia) in which patients have a choice of demand dose sizes. In an initial trial, patients could choose between 0.5, 1.0 or 1.5 mg morphine. Patients readily understood the system and were all 'satisfied' (n = 1) or 'very satisfied' (n = 9) with the system. Only two patients sought 'complete relief' from pain, most reported seeking 'moderate relief'. All patients obtained a 'lot of relief' or 'complete relief' with this patient-controlled analgesia system. This preliminary experience suggests that variable dose patient-controlled analgesia warrants further investigation and comparison with conventional patient-controlled analgesia.

Iron overload facilitates hepatic fibrosis in the rat alcohol/low-dose carbon tetrachloride model.

The role of iron deposition in initiating hepatic fibrosis in iron overload disorders is not clearly established, and it is becoming increasingly recognized that iron may be interacting with other potential liver-damaging agents. The authors therefore examined the interplay of iron and alcohol in rats administered subtoxic doses of carbon tetrachloride (CCl4) vapor at 20 ppm in customized chambers. At birth, the offspring of seven pregnant Porton rats were divided into two groups: one group was fed a normal rat chow diet and the other a diet supplemented with 3% (w/w) carbonyl iron for 10 weeks after weaning. In this latter group, the mothers were fed an iron supplement while breastfeeding. At 10 weeks, the animals from the first group (normal chow) were divided into two groups of six animals and fed a Lieber-DeCarli liquid diet with daily exposure to CCl4 vapor: group 1, liquid diet+CCl4; group 2, liquid diet+alcohol 150 kcal/l+CCl4. The animals from the second iron-supplemented group were divided into two groups of six animals and fed a liquid diet with 3% (w/v) carbonyl iron and exposed to CCl4 vapor for 10 weeks: group 3, liquid diet+iron+CCl4; group 4, liquid diet+iron+alcohol supplement+CCl4. Two animals from each group of six had a liver biopsy at 4, 6, and 8 weeks, and all animals were killed after 10 weeks of CCl4 exposure. After the first 10-week iron loading period, the rats fed the carbonyl iron-supplemented diet had a 10-fold elevation in hepatic iron concentration.(ABSTRACT TRUNCATED AT 250 WORDS)
