Brief Summary:
Children lose heat under general anaesthesia, thus temperature is routinely monitored during anaesthesia for all but the shortest cases, and active warming can be used to prevent hypothermia and its resulting complications. Temperature can be measured at several sites dependent on the type of surgery and patient factors. Previously a temperature probe has been sited in the lower third of the oesophagus (swallowing tube) but it is difficult to accurately place this without an X-Ray. Consequently it is more common to use a temperature probe placed in the nasopharynx (where the nose and throat meet), when the child is anaesthetised.
However the investigators do not know if the temperature in the nasopharynx correlates well with the real core temperature or not.This prospective, unblinded, agreement study will seek to find an agreement of 2 methods to measure temperature in children undergoing general anaesthesia with a breathing tube that has a leak.
Detailed Description:
It is known that temperature in the lower third of the oesophagus correlates well with the gold standard of core temperature measurement, namely the temperature of blood in the heart. It is not known if oesophageal and nasopharyngeal temperatures correlate in children on a breathing machine via a tube with leak. If this study were to find a good correlation between oesophageal and nasopharyngeal temperature, this would allow clinicians to confidently use the more feasible nasopharyngeal temperature probes.
For this study 100 children will have both nasopharyngeal and oesophageal temperatures measured during general anaesthesia, both in the presence and absence of a leak around the endotracheal tube.
It is hypothesised that even in the presence of a leak, the temperature difference between the two methods will be less than 0.5 degrees centigrade.
