Circulating Water Temperature-sensing Blanket Combined With Soft Silicone Foam Dressing To Prevent Pressure Sores In Extracorporeal Circulation Surgery

Objective:To investigate the effect of temperature variable circulating water blanket in combination with Soft silicone foam dressings to prevent pressure sores during cardiopulmonary bypass surgery.To find a more effective method for prevention of pressure sores and to provide the basis for this method's wide application in clinical practice.Method:In accordance with the set criteria, a total of 108 patients who were given cardiopulmonary bypass surgery in a First-Class tertiary hospital were randomly divided into two groups, the temperature variable circulating water blanket combined with Soft silicone foam dressing group(combined group) and Soft silicone foam dressing group( Soft silicone group). The nasopharyngeal and rectal temperatures were measured at the moment of starting anesthesia, start of cutting skin, the beginning and end of extracorporeal circulation and at the end of the surgery. The numbers of hypothermia patients(<36?) of the two groups were recorded. The extracorporeal circulation time was also recorded. The incidences of stage?and stage II pressure ulcers between two groups during the operation were compared.Result:During the operation, both the patients' nasopharyngeal and rectal temperature in combined group were higher than the Soft silicone group and the range of temperature change was smaller(P <0.05). The incidence of patients with hypothermia in combined group was significantly lower than that of Soft silicone group(P < 0.05). During cardiopulmonary bypass surgery the cooling and rewarming of the patients were done according to the operation process, the average whole time of the combined group was shorter the the Soft silicone group(P < 0.05). One stage I pressure ulcer occurred in the combined group, with the incidence of pressure ulcers 1.9%; 8 cases of pressure ulcers occurred in Soft silicone group, with the incidence of 14.8%, among which 7 cases were stage I, 1cases was stage II. There was a significant difference between the two methods in the happening of the pressure ulcers, and the difference was statistically significant.Conclusion : During cardiopulmonary bypass surgery, the use of temperature variable circulating water blanket combined with Soft silicone foam dressing can reduce the incidence of intraoperative hypothermia, shorten the operation time, and decrease significantly the incidence of pressure ulcers compared to single use of Soft silicone foam dressing, and this method is worth popularizing in clinical practice.
