The effect of intraoperative hypothermia upon blood transfusion needs and length of stay among gastrointestinal system cancer surgery.

Abstract

This cross-sectional study was performed to evaluate the relationship between intraoperative body temperature and the need for blood transfusion and length of stay in the post-anaesthetic care unit (PACU) or in the intensive care unit (ICU) among 79 patients undergoing elective oncology surgery of the digestive system. There was a statistically significant correlation between a lower temperature during surgery and medical diagnosis (p=.009), the use of bupivacaine anaesthesia (p=.016), anaesthesia time (p=.003) and anaesthesia type (p=.033), surgery time (p=.021) and surgery type (p=.002), volumes infused during the intraoperative period (p=.006), admission to the ICU (p=.032) and length of stay in PACU (p=.029). The lower the temperature when the patient is admitted to the operating room, the lower the temperature during the procedure (p˂.001). There was no association between the body temperature of patients and blood transfusion (p=.619). Hypothermia was associated with increased length of stay in the PACU, but was not associated with the need for blood transfusion during the intra- and postoperative periods. The use of preoperative passive warming methods allows patients to reach the operating room hypothermic.
