Randomized Controlled Trial Comparative Study Clinical TrialExamination of acetaminophen for outpatient management of postoperative pain in children.
We have examined acetaminophen (paracetamol) dosing for outpatient management of posttonsillectomy pain in children. Forty children, 5-15 years of age, undergoing tonsillectomy and their parents were randomly assigned to use a scheduled administration of acetaminophen in weight appropriate doses, 60 mg.kg-1.24h-1 orally, 90 mg.kg-1.24h-1 rectally, or to use acetaminophen 'as needed' according to present standards (control group). Postoperative pain was assessed by the child using the poker chip tool for the first three days after discharge. ⋯ The second day after discharge 22%-64% of the children in the study group and 36%-73% of the children in the control group rated severe pain. Recommended dose ranges of acetaminophen do not provide sufficient pain relief in children following tonsillectomy. Further studies are required to determine, whether higher doses of acetaminophen or analgesics with different analgesic properties will lead to improved analgesia in children following tonsillectomy.

Randomized Controlled Trial Clinical TrialOnset of neuromuscular blockade and intubating conditions one minute after the administration of rocuronium in children.
In a blinded randomized study intubating conditions were compared at one min following intravenous induction with propofol and either suxamethonium 1.0 mg.kg-1, or rocuronium 0.6 mg.kg-1. Onset time to maximal twitch depression, % block at one minute and clinical duration (time to 25% recovery) were measured. Sixty children undergoing elective tonsillectomy were recruited. ⋯ The median twitch height at one minute for suxamethonium was 0% (range 0-8%) and significantly greater (P < 0.001) at 5% (range 0-22%) for rocuronium. Despite this there was no difference in the intubating conditions at one minute with 25 excellent/5 good in the suxamethonium group and 27 excellent/3 good in the rocuronium group. We conclude that rocuronium 0.6 mg.kg-1 gives optimal intubating conditions at one minute in children.

The aim of this clinical audit was to evaluate the home recovery and complications of 104 daycase anaesthetized children, as well as parent satisfaction. A questionnaire, explained at the time of preoperative visit, was given to parents at hospital discharge and returned by mail. Opioids were administered in 19% of the children whereas regional anaesthesia was performed in 28% of cases. ⋯ Nevertheless, 94% were satisfied with the anaesthetic. A clinical audit is useful in detecting management deficiencies. Quality of home recovery may be improved by: wider use of perioperative analgesia, systematic prescription of take-home analgesia, designation of a hospital practitioner for advice, and closer collaboration with general practitioners.

Randomized Controlled Trial Clinical TrialOral midazolam premedication and postoperative behaviour in children.
We examined the effect of oral midazolam premedication on postoperative behaviour. Seventy children (ASA Physical Status 1 and 2; aged 1-10 yrs) were assigned randomly in a prospective, blinded fashion to receive either midazolam 0.5 mg.kg-1 (maximum 10 mg) or placebo. Behaviour assessments were made prior to medication, during induction of anaesthesia and 15 min following arrival to recovery room. ⋯ At one week follow-up, eight of 35 subjects receiving placebo had experienced adverse behaviour changes (nightmares, night terrors, food rejection, anxiety, negativism); 19 of 35 of the midazolam group experienced these changes (P < or = 0.02). At four week follow-up, most behaviour changes had resolved. Children given preoperative oral midazolam were less likely to cry and fight while being anaesthetized, and preoperative sedation was associated with increased incidence of adverse postoperative behaviour changes.

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.
