Randomized Controlled Trial Clinical TrialThe effect of ketorolac as an adjuvant to local anaesthetic infiltration for analgesia in paediatric umbilical hernia surgery.
After umbilical hernia surgery, and wound infiltration with bupivacaine 0.5%, 17 children were given ketorolac 0.5 mg.kg-1, with 18 controls receiving only the wound infiltration. No child experienced severe pain, but moderate pain was noted in patients in both groups. Objective and subjective pain scores were not different statistically at any point up to the morning after surgery.

Randomized Controlled Trial Clinical TrialDose of propofol required to insert the laryngeal mask airway in children.
We have assessed the ease of insertion of the Brain Laryngeal Mask Airway (LMA) after induction of anaesthesia with propofol in 60 healthy unpremedicated children aged between four and nine years. Patients were randomly allocated into three groups: group A = propofol 2.5 mg.kg-1; group B = propofol 3 mg.kg-1 and group C = propofol 3.5 mg.kg-1. Propofol was mixed with lignocaine 0.5 mg.kg-1. ⋯ There was no statistically significant inter group variation in systolic and diastolic arterial pressure or in heart rate for five min after induction. All measured cardiovascular changes were considered to be clinically insignificant in healthy children. We conclude it is safe and effective to insert a LMA immediately after induction of anaesthesia with propofol 3.5 mg.kg-1.

Randomized Controlled Trial Comparative Study Clinical TrialAnticholinergic prophylaxis does not prevent emesis following strabismus surgery in children.
One hundred and twenty-one children were studied in this prospective, randomized double-blind, placebo-controlled comparison of the effectiveness of anticholinergic prophylaxis for the prevention of emetic symptoms following strabismus surgery. The children were allocated to three groups, to receive placebo (n = 40), glycopyrrolate (n = 40) or atropine (n = 41). ⋯ Thirty percent (12/40) of patients in the placebo group, 25% (10/40) in the glycopyrrolate group, and 22% (9/41) in the atropine group experienced nausea and/or vomiting (difference not significant). It is concluded that prophylactic administration of anticholinergic agents during strabismus surgery in children despite being effective against the occurrence of the oculocardiac reflex, does not reduce the incidence of emetic symptoms.

Randomized Controlled Trial Comparative Study Clinical TrialCaudal analgesia with buprenorphine for postoperative pain relief in children.
Caudal buprenorphine was investigated as a postoperative analgesic in a randomized double blind study in thirty children aged 5-12 years undergoing lower abdominal and lower limb surgery. Comparison was made between two groups of patients, one group receiving plain bupivacaine and the other a combination of plain bupivacaine with buprenorphine. Postoperative analgesia was assessed using a linear analogue scale, and by the response to direct questioning of children using an illustration of sequence of faces. ⋯ The degree and duration of analgesia was far superior in the buprenorphine group and there was a highly significant difference in the requirement of postoperative analgesia between the two groups. There were no major adverse side effects and no motor weakness in either groups, however the incidence of nausea and vomiting was higher in the buprenorphine group. It is concluded that a combination of bupivacaine with buprenorphine administered through the caudal epidural space is a safe and reliable means of providing postoperative pain relief in children for up to 24 h.

Randomized Controlled Trial Comparative Study Clinical TrialDuration of apnoea in anaesthetized children required for desaturation of haemoglobin to 95%: comparison of three different breathing gases.
In this study, we compared three gas compositions to determine if the duration of apnoea for SpO2 to decrease is proportionate to the oxygen fraction of the gas prior to apnoea. Twenty-five patients ASA physical status 1-2 aged two months to 12 years were included in the study. Anaesthesia was induced via a mask with 5% sevoflurane and 66% N2O in oxygen. ⋯ T95 measured after breathing N2O/O2 and air/O2 were 34.6 +/- 5.7 and 28.8 +/- 4.7% of that measured after oxygen breathing (P < 0.001 vs oxygen breathing, P < 0.001 vs oxygen and N2O/O2 breathing), respectively. Preoxygenation before intubation was validated to delay the haemoglobin desaturation brought about by apnoea. An induction technique using a low FiO2 will allow rapid haemoglobin desaturation.
