Anesthetic Complications of Tympanostomy Tube Placement in Children.

Hoffmann KK, Thompson GK, Burke BL et al. Arch Otolaryngol Head Neck Surg. 128:1040-1043, 2002

The authors of this article reviewed the medical records of 3,198 children undergoing bilateral myringotomy and tympanostomy tube, placement (BMTT) 1,000 of the charts were reviewed prospectively, the rest were reviewed retrospectively. No patients were excluded.

The ASA, age and concurrent or chronic medical conditions of the patient was noted. In addition, the level of the anesthesia staff, anesthetic technique, perioperative adverse event and treatment of such events was recorded. Major events included laryngospasm, bradycardia, stridor, oxygen desaturation greater than 10% of baseline, or dysrhythmia and occurred in 1.9% of patients. Minor adverse events included upper airway obstruction, prolonged recovery (> than 30 minutes) emesis and persistent agitation. Minor events occurred in 9% and in > 31% were attributable to agitation or prolonged recovery. The incidence of adverse events was unrelated to ASA, age, type of anesthetic provider or type of anesthetic.

However, the presence of an acute or chronic pre-existing medical condition increased the incidence of an adverse event by 2.78.

Comments: This is a nicely done study that confirms the low anesthetic risk of patients undergoing BMTT. AS with many other procedures the presence of pre-existing disease increases the incidence of complications.
