SummaryThe incidence and duration of postoperative symptoms in children at home following day-case anaesthesia and surgery was evaluated using a questionnaire completed by parents of 551 children aged 4 months to 13.4 years (mean 3.8 years). They also evaluated the instructions given in hospital for care at home. The incidence of all symptoms was highest at home on the day of the operation. No postoperative symptoms were reported in 79 (14%) children. The incidence of pain was 56% and the only significant predictor was the type of operation, tonsillectomy being the most problematic (mild pain in 38% and severe in 25%; pain lasted 7 days or longer in 33%). Analgesics were given to 78% of all the children reported to have pain on the day of the operation, to 60% the next day and later to 58%; 19 (3%) children were given more than two doses per day. The instructions given in hospital for the treatment of pain were considered inadequate by 12% of parents. Postoperative nausea and vomiting occurred in 13% of children. Predictors by multiple stepwise logistic regression analysis were emetic symptoms in hospital, pain at home, age > 5 years and administration of postoperative opioid (pethidine or fentanyl). Opioid given during anaesthesia (fentanyl or alfentanil) did not increase the incidence. Emetic symptoms were most common after tonsillectomy (31%). The highest incidences of emetic symptoms (37%), sedation (96%) and dizziness (41%) occurred in children who had been given fentanyl for postoperative pain. Undertreatment of nausea in hospital was evident as only two children had received anti-emetics, even though 61 were reported to have emetic symptoms. Administration of effective anti-emetics should be encouraged, as emetic symptoms in hospital were the most significant predictor of nausea and vomiting at home. Treatment of pain at home and instructions for treatment of pain need to be improved.

A low-dose (4 mg), low-volume (0.8 mL), low-flow (2 min) technique with hyperbaric bupivacaine toward the dependent side oriented injection and maintenance of the lateral decubitus position for 10 min produced selective spinal anesthesia with rapid recession of motor block and early discharge home.

In this randomized and controlled trial, 64 adult ambulatory knee arthroscopy patients received either selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane. We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities, a shorter stay in the postanesthesia care unit, and earlier discharge home compared with GA with desflurane. Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group. No difference was seen in the fast-tracking possibilities or time in the postanesthesia care unit between the groups. Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS) in the SSA and GA groups, respectively. In the hospital, the pain scores were significantly (P < 0.001) lower in the SSA group compared with the GA group and the need for postoperative opioids was significantly (P = 0.008) larger after GA. The incidence of postoperative nausea and vomiting was 0% versus 19% in the SSA and GA groups (P = 0.024), respectively. We conclude that for outpatients undergoing knee arthroscopy, SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane.

After prophylactic administration of 4 or 8 mg of ondansetron IV, the incidence, duration and severity of pruritus were similar to placebo. Ondansetron does not prevent pruritus induced by low-dose intrathecal fentanyl.
