A systematic review of randomised controlled trials of the effects of warmed irrigation fluid on core body temperature during endoscopic surgeries

Abstract

Warming irrigating fluid should be considered standard practice in all endoscopic surgeries.

A prospective randomized double-blind study on the effects of the temperature of irrigation solutions on thermoregulation and postoperative complications in percutaneous nephrolithotomy

“…Administration of excessive amounts of irrigation fluids may contribute to heat loss. Studies of surgical procedures in which irrigation fluids are administered have produced conflicting results regarding whether irrigation fluids increase the risk of hypothermia [4][5][6][7][8][9].…”

“…There are a series of complications and adverse effects related to hypothermia; i.e., cardiac arrhythmias and ischemia, reduced drug metabolism, late emergence and late recovery from anesthesia, mental state changes, impaired renal function, impaired wound healing, elevated infection rates, bleeding disorders, shivering, elevated oxygen consumption, impaired peripheral circulation, hypercarbia, hypoxia, and lactic acidosis [1][2][3][4][5]. Because of these critical complications, all necessary precautions should be considered and meticulously applied when appropriate to avoid hypothermia.…”

“…Because of these critical complications, all necessary precautions should be considered and meticulously applied when appropriate to avoid hypothermia. Despite active and passive warming methods being used in the operating room, hypothermia incidence may be elevated in relation to the duration of anesthesia and the site and extent of surgery [5]. A decrease of 2-6°C in core body temperature is almost always noted in patients undergoing surgery under general anesthesia [2].…”

Prevention and management of inadvertent perioparatve hypothermia

“…Жидкости для интраоперационной иррига-ции должны быть предварительно подогре-ты до 38-40 °С [41]. Особые группы пациентов: дети.…”

The Effects of Perioperative Infusions of Amino Acid on Core Body Temperature

“…A systematic review recently reported that circulating water garments offered more effective temperature control than forced-air warming systems, and that both were better for temperature control than passive warming devices [5]. Another systematic review reported that the use of room temperature irrigation fluid led to greater decreases in core body temperature and increased the risk of perioperative hypothermia and shivering compared with warmed irrigation fluid [6]. An alternative technique is to promote the patients' own ability to generate heat by the infusion of amino acids, which are known to be effective at enhancing thermogenic effects and alleviating shivering during the perioperative period [7].…”
