Effects Of Three Warming Interventions On Temperature Maintenance During Open Abdominal Surgery

Purpose: To investigate the effects of three warming interventions on temperature maintenance during open abdominal surgery.Method: Ninety patients who underwent open abdominal surgery were assigned to three groups: 30 patients in the group with warmed cotton-blanket in about 50℃, 30 patients in the group with electric warming system in about 42-46℃, and 30 patients in the group with two warming interventions which is electric warming system in about 42-46℃and warming irrigation solution in about 37℃. Rectal temperature were recorded after entering the operating room, after intubation, at incision and every 30 minutes after that, at skin closed.Result: 1. Compared with the temperature when entering the operating room, the rectal temperature at intubation, incision and every 30 minutes after that, skin closed, were significantly lower in the warming cotton-blanket group. 2. There was the same result between the other two groups: Compared with the temperature when entering the room, there was no difference.Conclusion: During the open abdominal surgery, warming cotton-blanket and irrigation solution cannot prevent perioperative hypothermia. Electric warming system is the most efficient in maintaining perioperative normothermia during the three interventions.
