Randomized Controlled Trial Clinical TrialTropisetron reduces postoperative vomiting in children undergoing tonsillectomy.
In this patient, parent and investigator blinded, randomized, placebo-controlled study, children undergoing tonsillectomy (mean age 6.4 years) received either intravenous placebo (n=36) or tropisetron 0.2 mg.kg-1 up to 5 mg (n=35) at induction of anaesthesia with halothane, nitrous oxide and oxygen. Morphine and paracetamol were given in theatre for postoperative pain. ⋯ Minor side-effects occurred equally in both the placebo and active groups. Intravenous tropisetron is an effective and safe antiemetic for reducing postoperative vomiting in children undergoing tonsillectomy or adenotonsillectomy.

Computerized tomography of the lungs and arterial oxygen tension studies during apnoea in anaesthetized young lambs.
Computerized tomography (CT) of the lungs and arterial oxygen tension studies were performed during general anaesthesia in an animal model to understand changes in pulmonary atelectasis associated with anaesthesia in children during a 2 min apnoeic period. Six anaesthetized lambs were subjected to three periods of apnoea lasting 2 min each. ⋯ The results confirmed that significant background atelectasis was associated with general anaesthesia as found in adult human studies, but failed to demonstrate any increase in atelectasis during the period of induced apnoea. The decline in arterial oxygen tension in this study could be explained due to simple utilization of oxygen in keeping with physiological principles.
