Fluid heating system (SAF®): effects on clinical and biochemistry parameters in dogs submitted to inhalatory anesthesia

Abstract

PURPOSE: To evaluate and describe immediate effects of the infusion of saline solution heated by SAF® in bitches submitted to halothane anesthesia. METHODS: Thirteen bitches were employed and submitted to elective ovariohysterectomy in acclimatized operating room at 22ºC, allocated in two groups: GI, which received non-heated fluid and GII, which received fluid heated at 37ºC by SAF®. The following parameters were evaluated in 30-minutes intervals (M0, M30, M60 and M90): rectal and cutaneous temperatures (TR and TC), cardiac and respiratory frequencies (HR and ƒ), mean arterial blood pressure (MAP), serum concentration of urea, creatinin, serum activities of alanin aminotranspherasis (ALT), alkaline phosphatasis (ALP) and also hypnosis parameters. RESULTS: There were no significant alterations on clinical and biochemical, but there was group effect on mean arterial blood pressure, urea, ALT, ALP and hypnosis parameters. CONCLUSION: The isolated use of Fluid Heating System (SAF®) was not enough to avoid hypothermia or lead to significant clinical and biochemical alterations in bitches submitted to halothane anesthesia.

Inadvertent Perianesthetic Hypothermia in Small Animal Patients

“…Electric heating blankets, heat lamps, intravenous fluid warmers, warmed abdominal lavage fluids, circulating warm water pads, resistive polymer electric blankets, and forced warm air blankets are examples of active techniques. 36,[38][39][40][41][42][43] Intravenous fluid warmers appear to have minimal efficacy for combating hypothermia and must be placed on the intravenous fluid line as close to the patient catheter as possible. The use of warmed abdominal lavage solution over room temperature solution in patients undergoing celiotomy can increase the temperature of patients during anesthesia.…”
