Randomized Controlled Trial Comparative Study Clinical TrialContinuous epidural butorphanol relieves pruritus associated with epidural morphine infusions in children.
We examined the efficacy of epidural butorphanol to either prevent or relieve pruritus associated with epidural morphine infusion in children. Forty-six children were randomized to receive either epidural morphine (M) or epidural M with butorphanol (B) for postoperative analgesia. They received bupivacaine and either M 50 microg.kg-1 or the same dose of M plus B 10 microg.kg-1. ⋯ While the median sedation score in the first 24 h was 1 in both groups, there was a greater incidence of sedation scores of 2 in group B than group M (28% vs 12.3%; P=0.021). B 10 microg.kg-1 was not effective in preventing pruritus associated with bolus epidural administration of M 50 microg.kg-1 in children. B 1.2 microg.kg-1. h-1 was effective in relieving pruritus associated with continuous epidural infusion of M 6 microg.kg-1.h-1.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural sufentanil during paediatric cardiac surgery: effects on metabolic response and postoperative outcome.
The metabolic and neuroendocrine effects of caudal epidural analgesia were studied during paediatric cardiac surgery. Combined epidural and general anaesthesia (EPI group; n=12) was compared with deep opioid anaesthesia (DOA group; n=12). During anaesthesia and surgery, haemodynamic stability was similar in the two groups. ⋯ Incidence of postoperative life-threatening dysrhythmias was very low in the two groups. No significant reduction of postoperative mechanical ventilation, intensive care unit or hospital stays was reported with epidural analgesia. The incidence of postoperative infections was higher than expected in the two groups because of the poor properative clinical status of most of the children included in the study.

Randomized Controlled Trial Comparative Study Clinical TrialTropisetron plus dexamethasone is more effective than tropisetron alone for the prevention of postoperative nausea and vomiting in children undergoing tonsillectomy.
The 5-HT3 antagonists are effective in reducing postoperative nausea and vomiting (PONV) associated with paediatric tonsillectomy. Although prophylactic tropisetron can reduce the incidence of PONV by half, the resulting level of over 40% is still unacceptably high. The aim of this study was to evaluate the effect of adding dexamethasone to tropisetron. ⋯ Parents completed a daily diary for 5 days following discharge. Delayed vomiting occurred in 27% and 11% of the tropisetron and combination therapy groups, respectively (P=0.025) Sixteen percent and 9%, respectively, required medical attention (P=0.27). Tropisetron plus dexamethasone is more effective than tropisetron alone in reducing the incidence of PONV following paediatric tonsillectomy.

Randomized Controlled Trial Comparative Study Clinical TrialPretreatment with oral clonidine attenuates cardiovascular responses to tracheal extubation in children.
This study was designed to evaluate the effects of diazepam and clonidine orally given preoperatively on cardiovascular responses to tracheal extubation in children. Fifty children, ASA physical status I, aged 4-10 years, undergoing minor elective surgery (inguinal hernia, phimosis) received orally, in a randomized, double-blind manner, diazepam 0.4 mg.kg-1 or clonidine 4 microgram.kg-1 (n=25 of each). ⋯ The maximum changes in heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were less in patients who had received clonidine than in those who had received diazepam (HR, 12 vs 24; SBP, 14 vs 26; DBP, 9 vs 16; mean, P < 0.05). In conclusion, compared to diazepam given orally, pretreatment with oral clonidine attenuates haemodynamic changes associated with tracheal extubation in children.

Randomized Controlled Trial Comparative Study Clinical TrialEmergence agitation in paediatric patients after sevoflurane anaesthesia and no surgery: a comparison with halothane.
This study was designed to compare the emergence characteristics of sevoflurane with halothane anaesthesia in paediatric patients having no surgical intervention. We randomized 32 ASA I or II paediatric outpatients scheduled for magnetic resonance imaging scans to receive either halothane or sevoflurane anaesthesia. The primary outcome measure was the percentage of patients with emergence agitation, as defined by two different criteria. ⋯ Sevoflurane patients had a greater incidence of emergence delirium when a high threshold for agitation was defined (33% vs. 0%, P = 0.010) and a lower threshold for agitation was applied (80% vs. 12%, P<0.0001). Discharge times from the PACU and the SRU were not different. We conclude that there is an increased incidence of emergence agitation with sevoflurane anaesthesia compared to halothane independent of any painful stimulus.
