Randomized Controlled Trial Comparative Study Clinical TrialPostoperative morphine requirements, nausea and vomiting following anaesthesia for tonsillectomy. Comparison of intravenous morphine and non-opioid analgesic techniques.
Nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to be as effective as opioid analgesia following tonsillectomy in children. Opioids are still frequently used but tonsillectomy is associated with a high incidence of vomiting. This study has attempted to assess postoperative analgesic consumption and nausea and vomiting after general anaesthesia for tonsillectomy using either paracetamol premedication, paracetamol plus a NSAID or intravenous morphine to provide postoperative analgesia. ⋯ Postoperative nausea and vomiting was significantly less in the two groups which were not given intraoperative morphine. The number of vomiting incidents was also much less. We conclude that the preoperative administration of paracetamol alone provides satisfactory analgesia in many children but that supplementary analgesia is still required for some.

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 Clinical TrialRapid intravenous administration of ondansetron or metoclopramide is not associated with cardiovascular compromise in children.
This double blinded, placebo controlled, randomized, and prospective study investigated the effect of the rapid intravenous administration of ondansetron 0.15 mg.kg-1 or metoclopramide 0.25 mg.kg-1 on the heart rate, haemoglobin saturation, systolic blood pressure, and diastolic blood pressure in 45 ASA PS I-II children between two and 16 years of age prior to elective tonsillectomy. The study groups were not significantly different with respect to age, weight, or gender. We were unable to detect a change in heart rate, systolic or diastolic blood pressure, or haemoglobin saturation following the rapid administration of ondansetron or metoclopramide. We conclude intravenous ondansetron or metoclopramide (for the prevention of postoperative vomiting) are not associated with cardiovascular instability when administered rapidly to healthy children prior to elective surgery.

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 Comparative Study Clinical TrialPropofol reduces the incidence of vomiting after tonsillectomy in children.
We compared the effect of a propofol-based anaesthetic to an isoflurane-based anaesthetic on the incidence of postoperative vomiting in children following tonsillectomy. Thirty-nine children were enrolled in the study and randomized to receive one of the proposed anaesthetics. All patients underwent a mask induction with halothane, nitrous oxide, and oxygen. ⋯ Of 19 patients who received propofol, four vomited (21%); in contrast, of the 20 patients who received isoflurane, 11 vomited (55%). This difference is significant (P = 0.048 two-tailed Fisher's Exact Test). These data suggest that using propofol for anaesthesia can diminish the incidence of vomiting following tonsillectomy.
