ADVERSE EFFECTS, SEPARATION
we conducted a prospective controlled randomized double-blinded clinical trial including children aged between 2 and 15 years undergoing tonsillectomy surgery. The patients were randomly allocated to receive either an intranasal dose of clonidine (4 μg/kg) (clonidine group) or an equal volume dose of saline solution (control group) 30 minutes before entering the operating room. The level of anxiety assessed using the m-YPAS score was recorded before premedication, at the time of parent-child separation, and at the time of installation in the operating room. Acceptance of premedication, degree of sedation on entering the operating room as well as agitation on awakening, and sedation on arrival post-anesthesia care unit were noted. Adverse effects were recorded during the surgical procedure and in the postoperative recovery room.
