ABSTRACT

Objective To explore the effect of prevention intraoperative hypothermia of different heat preservation measures during craniotomy cerebroma resection surgery in the department of neurosurgery. Methods According to the inclusion criteria, a total of 90 patients with craniocerebral surgery were recruited and randomly divided into A, B, C groups with random number table method, and 30 patients in each group. And the three groups were respectively given different heat preservation measures of regular cover, regular cover with infusion heating, regular cover with force-air warming. Meanwhile the rectal temperatures of just entered into the operating room, immediately after anesthesia induction and every 30 minutes after induction of anesthesia, as well as the HR, BP, the amount of infusion and flushing liquor, operation time, incidence of chills during operation, the condition of surgical site infection and hospitalization days were recorded and analyzed statistically by means of the software of SPSS 13.0. Results Rectal temperatures of the three groups were no statistically significant difference (P>0.05) ,when the patients just were moved into the operating room, immediately after anesthesia induction and 0.5 h、1 h after anesthesia induction. The rectal temperatures of the three groups had statistically significant difference (P<0.05) from the 1.5h after anesthesia induction to the end of the surgery.The incidence rates of introperative hypothermia and chill of group C were 26.7%(8/30)and10.0% (3/30),lower than group A and group B60.0%(18/30), 33.3%(10/30)and 53.3%(16/30), 13.3%(4/30), meanwhile the statistically significant difference was found in these three groups (χ2=7.500, P=0.024;χ2=6.237, P=0.044).The volume of intraoperative blood loss and transfusion were 200(100, 300), 45(0, 60) ml, which lower than group A and group B300(200, 525), 215(0, 400) ml and 250(150, 500), 120(0, 200) ml, and statistically significant difference was also found in these three groups(H=7.612, P=0.022;H=6.194, P=0.045). Conclusions Regular cover with force-air warming can effectively reduce the incidence of intraoperative hypothermia and chills of craniotomy cerebroma resection patients in the department of neurosurgery and reduce intraoperative bleeding and transfusion volume, as well as ensure the effect of surgical treatment. So it′s worth popularizing in clinic.
