Timing of Surgery in Pediatric Patients Following Fever Recovery: a Prospective Cohort Study
- Conditions
- Fever
- Registration Number
- NCT06568809
- Lead Sponsor
- Second Affiliated Hospital of Wenzhou Medical University
- Brief Summary
Objectives: The timing of fever recovery may affect the risk of intra-operative hypoxemia in children undergoing elective surgery after SARS-CoV-2 infection. This study aims to determine the optimal timing for surgery by analyzing the occurrence of intra-operative hypoxemia in pediatric patients after they have recovered from a fever.
Methods: This prospective cohort study included 3053 children who had been infected with SARS-CoV-2 and developed fever, and scheduled to a surgery during March 2023 to August 2023, children with temperature recovery time ≥3 month were compared to children with temperature recovery time 0-8weeks. The primary outcome was measured as the incidence of intra-operative hypoxemia in SARS-CoV-2 infected children after their body temperature returned to normal. Logistic regression models were used to calculate the adjusted incidence of hypoxemia rate sratified by time (0-2 weeks; 3-4 weeks; 5-6 weeks; 7-8 weeks; ≥3 month) from body temperature recovery to the day of surgery.
- Detailed Description
This prospective cohort study included 3053 pediatric patients who had been infected with SARS-CoV-2 and developed fever, and scheduled to a surgery during March 2023 to August 2023.On the day of operation, the anesthesiologist in the children's operating room conducted a preoperative evaluation. Upon confirming that general anesthesia was appropriate, they proceeded to sign the informed consent for anesthesia. Three anesthesiologists were assigned to the research group and conducted a second preoperative visit to the children and their guardians in a separate room.
Body temperatures over 37.5 degrees Celsius was considered as fever. The time between body temperature recovery and surgery was collected as categorical factor and was scheduled to be analyzed in the following categories: 0-2 weeks; 3-4 weeks; 5-6 weeks; 7-8 weeks; And ≥ 3 months (control group). After entering the operating room, the children were routinely monitored (pulse oxygen saturation-SpO2, blood pressure and electrocardiogram). The anesthesia method and drug selection were decided by the anesthesiologist in the operating room. The following data were collected and recorded: age, height, weight and ASA classification; The preoperative medication and the perioperative use of narcotic drugs ; The induction technique; The primary airway device; The lowest value of SpO2 when the child entered the operating room, was intubated and was extubated; PRAEs (such as cough, wheezing, laryngeal spasm and bronchial spasm) occurred during operation; The treatment processwhen PRAEs occured; The total duration of operation. The primary outcome was the incidence of intra-operative hypoxemia.
