Background: Based on the previous investigation in our institution, the incidence of intraoperative hypothermia in\nneonates was high. Since September 1st, 2019, the recommendation had been launched to utilize less than equal to 1 L/min fresh\ngas flow during the neonatesâ?? surgical procedure. We therefore intended to evaluate the association between low\nfresh gas flow anesthesia and the occurrence of hypothermia in neonates undergoing digestive surgeries.\nMethods: A retrospective chart review, before-after study was conducted for neonates who underwent digestive\nsurgeries. The primary outcomes were the incidence of hypothermia. The secondary outcomes included hospital\nmortality, the value of lowest temperature, blood loss, mean body temperature during the surgery, the length of\nhypothermia during the surgery and postoperative hospital length-of- stay (PLOS).\nResults: 249 neonates fulfilled the eligibility criteria. The overall incidence of intraoperative hypothermia was 81.9%.\nThe low fresh gas flow anesthesia significantly reduced the odds of hypothermia [routine group: 149 (87.6%) versus\nlow flow group..............................
