What is The vasodilation and continuous intravenous fluid during surgery and anaesthesia cause: and explain in detail?
(Hypothermia): Ref: 303-Sabiston 17th (49-A. yadav- anesthesia 3rd) (135-37-HI7th)* Hypothermia can result from a preoperatively, intraoperatively or postoperately* A trauma patient involved with injuries in a cold environment can suffer significant hypothermia, similarly paralysis leads to hypothermia because of a loss of the shiver mechanism. Rapid resuscitation with cool IV fluids leads to hypothermia.* Rapid transfusions intra operatively can lead to hypothermia as wells as irrigation of intracavitary areas with cold saline and a prolonged operation with a low ambient room temperature.* The heat loss during GA may be as high as 30 K cal/hr* Hypothermia may be defined as core temperature less than 35degC (Mild- 28-35, Moderate 21-27degC and profound or severe < 20degC)* Each degree (degC) fall in temperature reduce the metabolic rate by 6 to 7%* BMR and oxygen consumption of body is decreased by 25% in mild hypothermia by 50% in moderate and 80% in profound hypothermia* The ideal operation theatre temperature for adults is 21degC and for children 28degC
