<prompt> The vasodilation and continuous intravenous fluid during surgery and anaesthesia cause:SeizureHypothermiaHypotensionVomiting  <response>: 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 calhr 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
