Abstract
PurposeOur aim in this study is to investigate efficacy of topical lidocaine spray for sedated esophagogastroduodenoscopy (EGD) in children.MethodsThe 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.ResultsSedation 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.ConclusionThe 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.
