Oxygen consumption in the newborn piglet during combined cold face/hot body exposure.
There is increasing evidence that hyperthermia can occur in cool climates because of overwrapping and that this practice precedes many deaths labelled as SIDS. We have attempted to test the hypothesis that the interaction of a cold face and a hot body might lead to further hyperthermia in a piglet model. Twelve non-sedated newborn piglets were studied over the first 10 days of development. Oxygen consumption was measured continuously during sleep. Animals were exposed to cold face conditions initially while the animal's body was kept warm and then while the body was hyperthermic. The results show that stimulation of the face with cool ambient air during conditions of raised metabolic activity (hot body) causes a fall in oxygen consumption towards basal levels. These studies do not, therefore, support the hypothesis that a further increase in metabolic rate occurs during combined cold face and hot body exposure in the piglet model.

Isolated liver perfusion: the choice of anaesthetic.
Perfused livers isolated from rats under halothane anaesthesia produced greater amounts of bile, released smaller amounts of aspartate aminotransferase, and had a much greater ability to maintain a constant concentration of glucose in perfusates than those obtained with ether or pentobarbitone. Little or no effect was shown on the ability of the liver to synthesize urea and to retain potassium within the organ. It appears, therefore,that halothane is the anaesthetic of choice when removing the liver from the laboratory rat.
