Perioperative electrolyte and fluid balance
Total body water (TBW) is consistently 70% of the lean body weight across age and sex ranges but varies as a percentage of actual bodyweight between groups and individuals owing to varied deposition of adipose tissue, which contains less water than muscle. TBW is 75% of total body weight in neonates, 70% in infants and 45% in the elderly. The average adult male (70 kg) has 60% of total body wei...
متن کاملPerioperative heat balance.
Hypothermia during general anesthesia develops with a characteristic three-phase pattern. The initial rapid reduction in core temperature after induction of anesthesia results from an internal redistribution of body heat. Redistribution results because anesthetics inhibit the tonic vasoconstriction that normally maintains a large core-to-peripheral temperature gradient. Core temperature then de...
متن کاملPerioperative thermoregulation and heat balance.
Core body temperature is normally tightly regulated to within a few tenths of a degree. The major thermoregulatory defences in humans are sweating, arteriovenous shunt vasoconstriction, and shivering. The core temperature triggering each response defines its activation threshold. General anaesthetics greatly impair thermoregulation, synchronously reducing the thresholds for vasoconstriction and...
متن کاملPerioperative fluid management.
Technological advances have changed how traditional surgical procedures are performed. New knowledge and surgical skills are required to effectively monitor the patient and manage fluids administered perioperatively. Today, selective fluids are used in a variety of surgical specialties. Complications of fluid therapy can occur that are intrinsic to each procedure within a specialty. This articl...
متن کاملPerioperative Fluid Management 2002
Although most aspects of perioperative fluid management have remained relatively constant for more than two decades, new concepts and practices are currently evolving. Until the mid-to-late 1960s, the prevailing strategy of perioperative fluid management was rigid restriction (1). After Shires et al. (2,3) convincingly demonstrated that major surgery and trauma were associated with fluid requir...
