The incidence of and risk factors for postoperative fever after cleft repair surgery in children.

PURPOSE: The characteristics of postoperative fever after cleft repair surgery in children are unknown. Thus, the purpose of this study was to determine the incidence of and risk factors for postoperative fever.

DESIGN AND METHODS: We retrospectively assessed 328 children who underwent cleft surgery at our hospital between March 2016 and April 2017 and were followed up for at least 3 days postoperatively. Fever was defined as a body temperature ≥38.0 °C.

RESULTS: Seventy-one percent (n = 233) of patients developed fever within 72 h postoperatively, and most cases of postoperative fever were benign. Patients most frequently developed fever within 24 h postoperatively, and the occurrence of fever significantly decreased between 24 and 72 h postoperatively (p < 0.001). The incidence of fever with temperatures between 38.0 °C and 39.0 °C was higher than that of fever with temperatures ≥39.0 °C (p < 0.001). The mean duration of an episode of fever was 4 h. The type of surgery, method of anesthesia, and duration of anesthesia and surgery were found to be correlated with postoperative fever after cleft surgery.

CONCLUSIONS: Most cases of postoperative fever after cleft surgery were benign occurrences. Postoperative fever after cleft repair surgery was characterized by a low grade, an early onset and a short duration in children. The method of anesthesia, duration of surgery and duration of anesthesia were risk factors for postoperative fever.

PRACTICE IMPLICATIONS: Our results could help healthcare providers to gain increased knowledge of the risk factors for fever and when and how to treat postoperative fever.
