- W4387477375 abstract "Introduction Hypothermia, defined as a core body temperature less than 36°C, is a common occurrence in the post operative period after cardiac surgery. A temperature of less than 35.5°C in the post operative period is known to be associated with significant morbidity and mortality. An audit cycle was conducted with the primary aim to assess the temperature management practice and its outcome in the department. Methods 37 adult patients undergoing elective cardiac surgery were included for this audit .The patients undergoing re explorations and chest closures, emergency surgery, prolonged CPB duration(>240mins) and patients undergoing hypothermic CPB were excluded. The first temperature recorded on the patients’ arrival to the ICU after the surgery was recorded. The practice of intra operative temperature management was assessed by a survey sent out to 9 cardiac anesthetic consultants. The findings of the audit were presented in the monthly anesthetic team meeting and a protocol was made to make modifications to the current practice. In order to aid implementation of the protocol a temperature management checklist was installed in all the cardiac surgical - anesthetic rooms. A re - audit was conducted 3 months later - the temperature on ICU admission of a total of 43 patients and a survey of temperature management practice of consultants were assessed using the same methods as for the audit. Results At the audit it was found that 10 out of the 37 patients (27%) of the patients had a temperature less than 36°C on arrival at the ICU with a minimum recorded temperature on arrival to ICU of 34.6°C . The temperature management practice was non - uniform in our department with a 100% use of HME and forced air warming device (Bair Hugger) whereas 44% used the fluid warmer, 22% did not use the fluid warmer and 33% of the members used the fluid warmer in selected cases.The heated mattress was not used routinely. The re audit conducted 90 days after the team meeting included 42 adult patients with the same criteria as the before. The results showed that 3 out of 42 patients (7%) of the patients had a temperature less than 36°C on arrival at the ICU. The temperature management practice was also more uniform with a 100% use of the HME, forced air warming and the heated mattress and 80% of the consultants were using fluid warmers in all patients and 20% in selected patients. Discussion This audit cycle demonstrated that owing to the non uniform practice in the department - post operative hypothermia was a significant problem in our cardiac surgical ICU. The NICE guidelines for hypothermia(2016) mention specific targets and methods to use for all surgeries but does not take into account the special considerations required for patients undergoing cardio pulmonary bypass. It appears from the above results that all 4 warming devices need to be used together for every patient in order to prevent post operative hypothermia in cardiac surgical patients." @default.
