Effects of preoperative nasal spray esketamine on separation anxiety and emergence agitation in pediatric strabismus surgery: A randomized clinical trial

To investigate the effects of preoperative nasal spray esketamine on separation anxiety and postoperative emergence agitation in pediatric strabismus surgery. Ninety children aged 3 to 6 years who underwent elective strabismus surgery were randomly divided into 3 groups that received 0.5 mg/kg (group S1), 1 mg/kg of esketamine (group S2), and the same volume of normal saline (group C) by nasal spray 10 minutes before surgery. The observation indicators of this test include the Ramsay sedation score, separation anxiety score, mask induction score, and the incidences of postoperative emergence agitation. Patient's heart rate, blood oxygen, post anesthesia care unit stay time, and any adverse events were recorded. The Ramsay sedation score was significantly lower in group C than those in groups S1 and S2 (P
