Esketamine, one of the two optical isomers of ketamine, is twice as effective as ketamine. The recommended dose of esketamine for intravenous anesthesia is 1.0-1.5 mg/kg [Several regimens are available for sedation in pediatric gastroscopy, among which the most widely used is propofol, which features a rapid onset, efficacy, and recovery time [Some studies have explored the dose of propofol in combination with different doses of esketamine used in pediatric painless gastroscopy. Zheng XS [In our study, the main adverse reactions were delayed awakening and hypoxemia induced by increased secretion during the examination. Except for two cases of delayed awakening, all pediatric patients were awakened within 30 min. Elevated secretions could be relieved with anticholinergic drugs to avoid the occurrence of cough and hypoxia. Hypotension is the main propofol-induced cardiovascular complication [The first noted limitation was that we only calculated the ED
