Investigation of Efficacy of Lidocaine Spray for Sedated Esophagogastroduodenoscopy in Children

PURPOSE: Our aim in this study is to investigate efficacy of topical lidocaine spray for sedated esophagogastroduodenoscopy (EGD) in children. METHODS: The endoscopy of children aged between 3-18 years who underwent EGD in our endoscopy unit. Intravenous (IV) midazolam and ketamine were used for sedation. Prior to sedation, endoscopy nurse applied topical lidocaine 10% with pump spray at 1 mg/kg dose in group 1, and distilled water via identically scaled pump spray in group 2, in a double blinded fashion. RESULTS: Sedation was not applied in 24.1% of the cases in topical lidocaine spray group (LS group) and in 5.7% of the cases in distilled water spray group (DS group). Gag reflex was observed in 6.5% of cases in LS group and 33.3% of cases in DS group (p=0.024), increased oral secretion was observed in 9.3% of cases in LS group and 51.7% of cases in DS group (p=0.038), sore throat was observed in 3.7% of cases in LS group and 35.6% of cases in DS group (p=0.019) and the difference was statistically significant. CONCLUSION: The study showed that topical pharyngeal lidocaine reduces both requirement and amount of IV sedation before EGD in children and sore throat, gag reflex and decreased oral secretion increase.
