Background: We conducted an audit to investigate the efficacy of a proposed standard operating procedure (SOP) on convective and conductive perioperative thermal management during paediatric cardiac anaesthesia. Methods: We retrospectively studied 26 consecutive children who underwent cardiac surgery under cardiopulmonary bypass (CPB). We applied a heating mattress and a forced-air blanket during anaesthesia induction, before CPB, during the rewarming period, and after discontinuation of CPB. Core body temperatures were recorded continuously. Results: All children (aged 1 day to 13.5 yr, median 25 months) were divided into three groups: < 5 kg (group I, n = 9), 5–15 kg (II, n = 8), and > 15 kg (III, n = 9). Mean (± SD) core body temperatures were as follows: at the start of surgery 35.8 ± 1.0°C (I), 35.9 ± 0.6°C (II), and 36.3 ± 0.3°C (III); at the start of bypass 35.9 ± 1.1°C (I), 36.4 ± 1.1°C (II), and 36.5 ± 0.7 °C (III). Temperatures after rewarming were 36.4 ± 0.4 °C (I), 36.2 ± 0.4 °C (II), and 36.0 ± 0.4°C (III). After weaning from bypass, core body temperatures were 36.7 ± 0.9°C (I), 37.3 ± 0.7°C (II), and 37.1 ± 0.7°C (III). Normothermia on admission to ICU was maintained in all but three small infants. Conclusions: In children undergoing cardiac surgery, a combination of convective and conductive warming can effectively ensure perioperative normothermia before and after CPB. peerReviewed |
