Abstract 【Objective】To study the effect of forced air warming (FAW) in perioperative hypothermia, complications, body stress and inflammatory response in laparoscopic surgery. 【Methods】A total of 86 patients who underwent laparoscopic surgery in our hospital from June 2017 to May 2021 were selected and divided into the observation group (n=43) and the control group (n=43) according to random number table method. The control group received conventional insulation intervention, while the observation group received FAW intervention. Nasopharyngeal temperature before anesthesia (T0), after induction of anesthesia (T1), 30 min after skin incision (T2), 60 min after skin incision (T3), 10 min (T4) after PACU and 2d (T5) after surgery were measured in the two groups. Perioperative indexes, such as operation time, blood transfusion volume, intravenous fluid volume, abdominal flushing fluid volume, extubation time, recovery time, stay in PACU time, hypothermia and postoperative complications in the two groups were compared between the two groups. Levels of stress factors such as serum adrenalin (E) and norepinephrine (NE) and serum levels of c-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor -α (TNF-α) and other inflammatory factors before and 3 days after surgery were compared between the two groups as well. 【Results】There was no difference in nasopharyngeal temperature between the two groups at T0, T1 and T5 (P>0.05). At T2, T3 and T4, nasopharyngeal temperature in the observation group was higher than that in the control group (P<0.05). The operative time, the amount of intravenous blood transfusion, the amount of fluid infusion, the amount of abdominal flushing fluid, the time of recovery and the time of stay in PACU in the observation group were all lower and shorter than those in the control group (P<0.05). The incidence of hypothermia and postoperative complications in the observation group were lower than those in the control group (P<0.05). Serum E and NE levels at 3d after operation in the observation group were lower than those in the control group (P<0.05). On 3d after operation, serum CRP, IL-6 and TNF-α levels in the observation group were lower than those in the control group (P<0.05). 【Conclusion】Application of FAW can effectively maintain perioperative core body temperature of patients undergoing laparoscopic surgery, prevent perioperative hypothermia and complications, reduce body stress, avoid inflammatory reactions and contribute a lot to postoperative recovery of patients.
