Prophylactic administration of analgesics before surgery can decrease the intraoperative anaesthetic requirement and decrease pain during the early postoperative period. In a double-blind, placebo-controlled study involving 90 healthy ASA physical status I or II children undergoing bilateral myringotomy, we compared the postoperative analgesic effects of oral acetaminophen and ketorolac, when administered 30 min before induction of anaesthesia. Patients were randomized to receive saline (0.1 ml.kg-1), acetaminophen (10 mg.kg-1) or ketorolac (1 mg.kg-1) diluted in cherry syrup to a total volume of 5 ml. Anaesthesia was induced and maintained with halothane and nitrous oxide via a face mask. Postoperative pain was assessed by a blinded observer using an objective pain scale. The three study groups were similar with respect to demographic data, duration of anaesthesia and surgery, induction behaviour, oxygen saturation, incidence of postoperative emesis and, recovery times. The ketorolac group had lower postoperative pain scores and required less frequent analgesic therapy in the early postoperative period compared with the acetaminophen and placebo groups. In contrast, there were no differences in pain scores or analgesic requirements between the acetaminophen and the placebo groups. We conclude that the preoperative administration of oral ketorolac, but not acetaminophen, provided better postoperative pain control than placebo in children undergoing bilateral myringotomy.

The intraoperative use of opioid analgesics decreases the volatile anesthetic requirement and provides for pain relief in the early postoperative period. In a randomized double-blind, placebo-controlled study involving 95 ASA physical status 1 or 2 children (ages 5-15 yr) undergoing general anesthesia for elective operations, we compared postoperative analgesia following the intraoperative intravenous (iv) administration of ketorolac, a nonsteroidal antiinflammatory drug or morphine, an opioid analgesic. After induction of general anesthesia and before the start of the surgical procedure, children received equal volumes of saline, morphine (0.1 mg.kg-1, iv) or ketorolac (0.9 mg.kg-1, iv). Postoperative pain was evaluated by the child using a 10-cm linear visual analog scale (VAS) and by a blinded observer using both a VAS and an objective pain scale (OPS) in the postanesthesia care unit (PACU). There were no statistically significant differences in the VAS and OPS scores in the PACU or in the postoperative analgesic requirements in children receiving morphine or ketorolac. The placebo group had a significantly higher VAS and OPS score and required earlier and more frequent analgesic therapy in the PACU compared to the two analgesic groups. Patients receiving ketorolac had less postoperative emesis than those receiving morphine. We conclude that ketorolac (0.9 mg.kg-1) is an effective alternative to morphine (0.1 mg.kg-1) as an iv adjuvant during general anesthesia, and in the dose used in this study, is associated with less postoperative nausea and vomiting in children.

Postoperative pain management is still a grossly neglected field. In most cases, antipyretic analgesics alone are insufficient during the early postoperative period. Powerful narcotics are often avoided or underdosed because they are associated with the risk of respiratory depression. Some authors recommend combined infusion of tramadol and metamizole, which is assumed to provide sufficient pain relief without the risk of respiratory depression. However, this regimen has not yet been investigated in a study that meets currently accepted scientific standards. METHODS. Sixty patients who underwent vaginal hysterectomy were included in a randomised, prospective double-blind study. Thirty women received two placebo suppositories immediately after induction of anaesthesia and a postoperative infusion of tramadol and metamizole (400 mg tramadol plus 5 g [= 10 ml] metamizole in 500 ml electrolyte solution). The 30 women of the control group received two ibuprofen suppositories (585.2 mg) preoperatively and a post-operative tramadol infusion (400 mg tramadol plus 10 ml placebo [NaCl 0.9%] in 500 mg electrolyte solution). The patients of both groups received 125 ml of the appropriate infusion solution as a loading dose over 10 min (corresponding to 1.25 mg metamizole and 100 mg tramadol in the metamizole/tramadol group or 100 mg tramadol in the ibuprofen/tramadol group) 10 min after awakening. The remaining solution was administered at an infusion rate of 12.5-25 ml/h (corresponding to 125-250 mg metamizole and 10-20 mg tramadol/h or 10-20 mg tramadol/h). On request or when complaining of stronger pain, the patients received an additional bolus infusion of 125 ml over 10 min. In case of insufficient pain reduction despite repeated infusion of 125-ml boli or consumption of the entire infusion solution, the patients discontinued the study and received demand-adapted intravenous titration of piritramide. Postoperative pain was evaluated on the visual analogue scale (VAS) and the 101-point numerical rating scale immediately before the start of the infusion. Pain evaluation was repeated 20, 30, 40, 60, 100, 120, and 240 min after awakening accompanied by registration of heart rate, respiratory rate, systolic and diastolic blood pressure, and side effects. RESULTS. About 60% of the entire infusion solution was administered within 60 min in both groups. Significant postoperative pain reduction in both groups and on both the 101-point scale and the VAS was observed only at 100, 120, and 240 min after awakening. In the tramadol/metamizole group, nausea occurred in 7 cases and vomiting in 1. Nine patients in this group additionally required intravenous piritramide because of insufficient pain relief. In the tramadol/ibuprofen group, 8 patients complained about nausea and 4 patients vomited. Six patients additionally received intravenous piritramide because of insufficient pain reduction. CONCLUSIONS. Satisfactory pain reduction occurred rather late despite high doses of both the tramadol/metamizole and the tramadol/ibuprofen. Both analgesic combination must be regarded as insufficient after inhalational anaesthesia because of the very slow onset of action and the high failure rate.

One hundred and sixty-four patients scheduled for elective termination of pregnancy under general anaesthesia were randomly assigned to receive one of three different supplements to propofol and oxygen in nitrous oxide anaesthesia: 0.1 mg fentanyl, 0.5 mg alfentanil or placebo. Postoperative pain and nausea, as well as complications during anaesthesia were studied. There were no differences in complications or complaints by surgeons during anaesthesia, and no patient in any group reacted unsatisfactorily to surgery. The patients in the placebo group consumed significantly more propofol during the procedure (P less than 0.001). No differences were seen in time until hospital discharge between the three groups. Complaints about postoperative pain were significantly less frequent among patients receiving fentanyl (P less than 0.01). The number of patients requesting postoperative analgetics, however, did not differ. There was no difference in the frequency of nausea or vomiting, but postoperative pain was found significantly to increase complaints of nausea (P less than 0.01) and also time until hospital discharge (P less than 0.01). In conclusion, opioid supplementation lowered the amount of propofol needed for anaesthesia. Alfentanil 0.5 mg did not improve the postoperative course. Fentanyl 0.1 mg decreased the frequency of postoperative pain without increasing the time to hospital discharge.

Forty-five patients undergoing total abdominal hysterectomy were randomly divided into three groups. An epidural tube was inserted into one of the following three sites, Th11-12, L2-3, and caudal region. General anesthesia was then maintained with nitrous oxide-oxygen-enflurane, and pancuronium bromide. Morphine hydrochloride 2 mg in 8 ml of normal saline was administered into one of the designated epidural spaces one to two hours before the assumed end of surgery. Postoperative pain was assessed every four hours after the end of the operation until the next morning. Morphine exerted a relatively profound and prolonged analgesic effect in 40% of the Th11-12 group of patients, as well as in 6.7% of the L2-3 and caudal groups. But, supplementary analgesics were necessary in the other patients. No significant differences were found in the degree and extension of postoperative pain, as well as the doses of supplementary analgesics among the three groups. Adverse effects, such as nausea, vomiting and itching, occurred in 30 to 40% of each of the morphine administered groups. Though morphine was applied into different spinal levels, this clinical study did not show any difference in extension of analgesia. The epidurally applied morphine may be distributed widely in the spinal arachnoid space after some time, and may exert an effect on the brain as well as on the spinal nerves. When morphine is administered epidurally one to two hours before the end of a surgical operation, selection of an injection site according to the dermatome level of the skin incision may be unnecessary.

Few advancements in postoperative pain control in children have been made despite longstanding inadequacies in conventional intramuscular analgesic regimens. While overestimating narcotic complication rates, physicians often underestimate efficacious doses, nurses are reluctant to give injections, and many children in pain shy away from shots. This study prospectively focuses on the safety, efficacy, and complication rate of intermittent intramuscular (IM) versus continuous intravenous infusion (IV) of morphine sulfate (MS) in 46 nonventilated children following major chest, abdominal, or orthopedic surgical procedures. Twenty patients assigned to the IM group had a mean age of 6.17 years and a mean weight of 23.0 kg. Twenty-six patients assigned to the IV group had a mean age of 8.74 years and a mean weight of 27.4 kg. The mean IM MS dose was 12.3 micrograms/kg/h while the mean IV dose was 19.8 micrograms/kg/h (P less than .001). Postoperative pain was assessed with a linear analogue scale from 1 to 10 (1, "doesn't hurt"; 10, "worst hurt possible") for 3 days following operation. Using the analysis of covariance (ANACOVA), nurse, parent, and patient mean pain scores in the IV group were significantly lower than those of the IM group when controlled for age, MS dose, and complications (P less than .007). Nurse assessment of pain correlated well with the patient and parent assessments (Pearson correlation coefficients greater than 0.6). Not only did IV infusion give better pain relief than IM injections, but there were no major complications such as respiratory depression. Minor complications in this study (nausea, urinary retention, drowsiness, vomiting, hallucinations, lightheadedness, and prolonged ileus) were not significantly different between IM and IV groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Ambulatory laparoscopic cholecystectomy was attempted using a new anaesthetic regimen in 50 patients. 46 patients were discharged 3-5 hours after operation, four were admitted to and remained in hospital for 1-5 days, one for psychosocial reasons, one because of emesis and two because of extended surgery. 45 of 46 ambulatory patients were generally satisfied after having experienced ambulatory cholecystectomy. Postoperative pain and nausea were moderate. Only 24% needed parenteral opioids postoperatively, and only 30% needed anti-emetic treatment. One woman suffered unacceptable pain and discomfort during the first two days at home, and would not prefer to have ambulatory treatment (questionnaire). Four patients were readmitted. Two had a forgotten stone in the common bile duct and underwent ERCP to extract the stone, without further complications. The third had a clip occluding the common bile duct. She was reoperated on in order to remove the clip and insert a T-tube in the common bile duct. Finally one woman was readmitted because of abdominal pain and vomiting, of which we never found the cause. She recovered spontaneously. Even though serious complications associated with biliary surgery were unavoidable in this ambulatory series, we have documented that patients can be operated on safely in this way. Most patients were very content, and experienced much less postoperative discomfort than they had expected.

The purpose of this study was to compare the effect of local anaesthesia (LA) with that of caudal anaesthesia (CA) on postoperative care of children undergoing inguinal hernia repair. This was a randomized, single-blind investigation of 202 children aged 1-13 yr. Anaesthesia was induced with N2O/O2 and halothane or propofol and maintained with N2O/O2/halothane. Local anaesthesia included ilioinguinal and iliohypogastric nerve block plus subcutaneous injection by the surgeon of up to 0.3 ml.kg-1 bupivacaine 0.25% with 5 micrograms.kg-1 adrenaline. The dose for caudal anaesthesia was 1 ml.kg-1 up to 20 ml bupivacaine 0.2% with 5 micrograms.kg-1 adrenaline. Postoperative pain was assessed with mCHEOPS in the anaesthesia recovery room, with postoperative usage of opioid and acetaminophen in the hospital, and with parental assessment of pain with a VAS. Vomiting, time to first ambulation and first urination were recorded. The postoperative pain scores and opioid usage were similar; however, the LA-group required more acetaminophen in the Day Care Surgical Unit. The incidence of vomiting and the times to first ambulation and first urination were similar. The LA-patients had a shorter recovery room stay (40 +/- 9 vs 45 +/- 15 min, P < 0.02). The postoperative stay was prolonged in the CA group (176 +/- 32 vs 165 +/- 26 min, P = 0.02). We conclude that LA and CA have similar effects on postoperative care with only slight differences.

Fifty-four ASA I and II children 1 to 10 yr of age undergoing strabismus surgery were randomized to receive in a double-blind fashion intravenous ketorolac (0.9 mg/kg), fentanyl (1 microgram/kg), or saline placebo (2 mL) during a standardized general anesthetic. Patients received no analgesic or antiemetics intraoperatively except for the study drug. Patients receiving ketorolac or placebo compared to fentanyl had a significantly lower incidence of postoperative vomiting in the day surgery unit (DSU) (P = 0.03) and overall (DSU plus home) (P = 0.005). The severity (number of episodes) of post-operative vomiting was significantly lower in the DSU, at home (first 24 h after hospital discharge), and overall for patients receiving ketorolac or placebo compared to fentanyl (P < 0.01). Postoperative pain scores and frequency of acetaminophen administration did not differ among the study groups, suggesting that the intraoperative use of ketorolac or fentanyl during pediatric strabismus surgery is unnecessary. No patients required fentanyl postoperatively, indicating that rectal acetaminophen administered in the postanesthesia recovery room provides sufficient analgesia for pediatric strabismus surgery. In conclusion, neither ketorolac nor fentanyl was associated with less postoperative vomiting or analgesic requirements compared to saline placebo administered during pediatric strabismus surgery. Fentanyl should be avoided, as it was associated with a significantly greater incidence of postoperative vomiting compared to ketorolac or placebo.

Sixty patients undergoing elective total hip replacement under spinal anaesthesia were randomly assigned to receive either intrathecal (IT) diamorphine 0.75 mg (n = 30) or IT morphine 1.0 mg (n = 30). Postoperative pain scores, analgesic requirements and side effects were assessed by a blinded observer. Postoperative pain scores were broadly similar and satisfactory for both groups but the amount of additional IV morphine required to achieve this was significantly reduced in the morphine compared with the diamorphine group (P < 0.05). Twelve of the morphine group required no postoperative analgesics compared with four in the diamorphine group (P < 0.02). There were no differences between the groups in the incidence of side effects such as emesis and pruritus. No significant postoperative respiratory depression was noted. In the doses used intrathecal morphine provided superior postoperative analgesia to that of intrathecal diamorphine.
