EFFECTIVENESS OF INTRAVENOUS LIDOCAINE ADMINISTERED BEFORE INDUCTION IN PREVENTING FANTANYL INDUCED COUGH IN PEDIATRIC SURGICAL PATIENTS
Main Article Content
Abstract
Methods: Study design: a randomized, double-blind clinical trial conducted at Saint Paul General Hospital. Participants: one hundred pediatric patients aged 4-10 years, ASA physical status I-II, undergoing elective surgery under general anesthesia, were randomly allocated in a 1:1 ratio. Intervention: the Lidocaine group received intravenous Lidocaine 1 mg/kg, while the control group received a placebo (0.9% normal saline). Both were administered one minute prior to induction with intravenous Fentanyl at 2 µg/kg. Outcome measures: the incidence of cough and the number of cough episodes following Fentanyl injection were recorded. Cough severity was classified as mild (1-2 episodes), moderate (3-4 episodes), or severe (≥ 5 episodes).
Results: The incidence of Fentanyl-induced cough was significantly lower in the Lidocaine group compared with the control group (14% vs. 50%, p < 0.05). No cases of severe cough were observed in the Lidocaine group, whereas 8% of patients in the control group experienced severe coughing episodes. Overall, cough severity was milder in the Lidocaine group, with most cases classified as mild, compared with the control group.
Conclusion: Intravenous administration of Lidocaine at a dose of 1 mg/kg prior to Fentanyl injection markedly reduces both the incidence and severity of Fentanyl-induced cough in children. This is a safe, easily applicable preventive measure that may offer meaningful benefits in pediatric anesthesia practice
