This study involves ventilation of the lungs with warmed humidifed anaesthetic gases during prolonged elective abdominal operations. Tympanic, oesophageal and toe temperatures were compared bewteen twenty warmed and twenty un-warmed patients at various times during operation and recovery. Fifty per cent (10/20) unwarmed patients shivered in the recovery room, while none of the warmed patients shivered. Our data indicate that pulmonary ventilation with warm humidified anaesthetic gases provides heat transfer by the lungs, preventing hypothermia during operation and post -anaesthesia shivering is prevented by maintaining the patient normothermic in both the operating room and the recovery room.

Arterial oxygenation during artificial ventilation. The effect of airway closure and of its prevention by positive end-expiratory pressure.
Airway closure and arterial blood gases were measured in 11 healthy subjects both before and during anaesthesia with artificial ventilation, prior to routine surgery. The functional residual capacity was then increased by positive end-expiratory pressure (PEEP), so that ventilation took place at a lung volume where no airway closure was present, and the effect on arterial oxygenation was again investigated. ⋯ There was no improvement in arterial oxygenation on increasing functional residual capacity (FRC) in either group. It may well be that this failure to improve oxygenation was due to a deleterious effect of PEEP on the circulation, even though the PEEP was the minimum required to abolish airway closure.

Anesthesia for small animal pediatric and geriatric patients. I. Anesthesia for small animal pediatric patients.
Anesthetic management of the pediatric patient is a challenge which can give rise to a most rewarding anesthetic management if one takes into consideration the normal physiological function of the pediatric patient. One should choose the appropriate medications which may safely be administered to an animal of this age. Control of anesthesia through the use of appropriate anesthetic equipment and the use of appropriate monitoring will aid safe management. The selection of adjunct medications can achieve control of complications and aid ultimate uncomplicated recovery.
