Does Fluid Requirement Decrease With the Use of Pneumatic Compression Device on Lower Limbs

Impact of Intra-operative Use of Peristaltic Pneumatic Compression Device on Haemodynamics Vis-à-vis Fluid Requirement During General Anaesthesia and Surgery:A Randomized Prospective Study

Impact of intraoperative use of pneumatic peristaltic compression device on hemodynamics vis a vis on fluid requirement during general anaesthesia and surgery.

Induction of general anaesthesia is associated with cardiac depression and peripheral vasodilatation resulting in hypotension .This hypotension can be corrected by giving intravenous fluid, or the vasoconstrictor. While optimum fluid balances in the perioperative period is of vital importance in overnight fasting patients to correct the fluid deficit, any fluid overload is not only counterproductive to the heart function but is associated with fluid retention in body and edema in postoperative period.

Peristaltic pneumatic compression device, a variant of intermittent sequential compression of legs, uses higher pressure and longer compression cycles to avoid venous stasis in immobilized patients. Sequential compression devices have sleeves with pockets of inflation, which works to squeeze on the appendage in a milking action .The most distal areas will inflate initially, and the subsequent pockets will follow in the same manner. The primary aim of the device is to squeeze blood from the underlying deep veins to proximal side. When the inflatable sleeves deflate, the veins will replenish with blood. The intermittent compressions of the sleeves will ensure the movement of venous blood . Peristaltic Pneumatic Compression of the legs significantly reduces fluid demand and enhances stability during minor ear, nose, and throat surgery. Peristaltic Pneumatic Compression has the potential to support fluid restriction regimens during surgery .
