Randomized Controlled Trial Comparative Study Clinical TrialProphylactic therapy with granisetron in the prevention of vomiting after paediatric surgery. A randomized, double-blind comparison with droperidol and metoclopramide.
The antiemetic efficacy of droperidol, metoclopramide and granisetron was compared with placebo in the reduction of vomiting after paediatric surgery (the extremities; inguinal hernia; and phimosis) during general inhalational anaesthesia. One hundred children, ASA physical status I, 4-10 years of age, were enrolled in a prospectively, randomized, double-blind investigation and assigned to one of four treatment regimens: placebo (saline, n = 25), droperidol (50 micrograms.kg1, n = 25), metoclopramide (0.25 mg.kg-1, n = 25) or granisetron (40 micrograms.kg-1, n = 25). ⋯ The incidence of adverse events postoperatively was not different among the treatment groups. In conclusion, granisetron 40 micrograms.kg-1 is a better antiemetic than droperidol and metoclopramide when compared to placebo for the prevention of postoperative emesis in children.

Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine in paediatric surgery: preliminary results.
In a double blind study 40 patients, aged 1-9 years, undergoing elective minor surgery were examined and randomly divided in two groups (20 children each). After light general anaesthesia Group 1 received caudal injection of bupivacaine 0.25% 2 mg.kg-1 while Group 2 received 0.2% ropivacaine 2 mg.kg-1. ⋯ No motor block was apparent at awakening in either group and no side effect was noticed. In conclusion ropivacaine seems to be an effective and safe drug in paediatric regional anaesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialA double blind comparison of droperidol and ondansetron for prevention of emesis in children undergoing orthopaedic surgery.
Emesis is common in the postoperative period following epidural opioid and general anaesthesia. Eighty patients ages two to 14 years scheduled for major orthopaedic surgery were enrolled in a randomized, double-blind study to compare the prophylactic effects of ondansetron, droperidol and a placebo for the prevention of postoperative emesis. Each child was assigned at random to one of the four treatment groups: ondansetron 100 micrograms.kg-1, ondansetron 50 micrograms.kg-1, droperidol 60 micrograms.kg-1 and saline control. ⋯ Ondansetron (50 micrograms.kg-1) and droperidol groups had lower incidence of PONV compared to the control group. The ondansetron (100 micrograms.kg-1) group had a significant decrease in the incidence of emesis. We conclude that the prophylactic administration of ondansetron (100 micrograms.kg-1) is more effective than droperidol and ondansetron (50 micrograms.kg-1) and superior to saline (P < 0.02) for the prevention of emesis before epidural opioid and general anaesthesia.

Randomized Controlled Trial Clinical TrialConvective warming blankets improve peroperative heat preservation in congenital heart surgery.
Peroperative heat preservation, following hypothermic cardiopulmonary bypass (CPB) in children, has always been a challenge to the anaesthetist. We studied the efficiency of a convective heating system on peroperative heat preservation in 50 children undergoing congenital heart surgery. Twenty-five children, rewarmed by CPB and heating mattress, were randomly selected (Group 1). ⋯ At the end of bypass there was no significant difference between the two groups. At the end of operation the central and peripheral temperatures were significantly higher in Group 2. In conclusion convective warming blankets are effective in keeping or even raising the temperature following congenital heart surgery.

Randomized Controlled Trial Clinical TrialTranscutaneous CO2 tension effects of clonidine in paediatric caudal analgesia.
In adults, clonidine when added to bupivacaine, results in no detectable respiratory depressant effect except when carbon dioxide challenge is performed. However, to date no investigations have quantified this in children. Twenty-four children (nine months to seven years) were randomized in a double-blind study into two groups. ⋯ The sedation score decreased with time in both groups, and the score time interval was significantly higher in the clonidine group (P < 0.05). All the patients left the recovery room with a sedation score of 1, excepting four in the clonidine group with a sedation score of 2. Clonidine 1 microgram.kg-1 with 0.25% bupivacaine mixture in caudal analgesia in children did not induce an increase in tcPCO2 despite prolonged sedation.
