Comparing the effects of Total Intravenous Anesthesia and Sevoflurane on Respiratory Adverse Events in under-7 Children with Upper Respiratory Tract Infection

Background: Controlling the respiratory complications of anesthesia in children is one of the most challenging situations. The present study aimed to compare intravenous and inhalation anesthesia in respiratory adverse events in children under 7 with upper respiratory tract infection (URTI). Method: All children with URTI referring to Labbafinejad hospital in Tehran for emergency surgery were randomly divided into two groups. The first group received Total Intra-Venous Anesthesia (TIVA) inducer and maintenance, and the second group received inhalation (Sevoflurane). The two groups were compared in terms of respiratory events at different times Laryngeal Mask Airway (LMA) implantation time, interoperation, LMA removal, and recovery). Results: There were significant differences between the groups (p-value 0.05) (1) before induction in terms of using respiratory sub-muscles, (2) during LMA implantation in terms of oxygen saturation percentage, stridor, cyanosis, laryngospasm, bronchospasm, and the presence of breath hold, (3) during LMA removal in terms of oxygen saturation percentage, cyanosis, laryngospasm, and bronchospasm, (4) after LMA removal in terms of stridor, cyanosis, the use of respiratory sub-muscles, persistent cough, and breath hold, and (5) in the Post-Anesthesia Care Unit (PACU) in terms of stridor and persistent cough. Conclusion: in children with URTI, who have undergone emergency surgery, due to less PRAE in the intravenous method with Propofol, the use of TIVA method can reduce the risk of related adverse events.
