Abstract

OBJECTIVE:

To assess the safety and efficacy of conscious sedation (CS) in children undergoing emergency department incision and drainage (I&D) of peritonsillar abscesses (PTAs).

DESIGN:

A 33-month retrospective chart review of all children presenting to the emergency department with the diagnosis of a PTA or peritonsillar cellulitis. Children who underwent CS prior to I&D were compared with children without CS for complications and efficacy.

SETTING:

St Louis Children's Hospital, an academic tertiary care pediatric hospital.

PATIENTS:

Fifty-two children were enrolled; 30 PTAs were drained with CS in 27 children (3 underwent I&D twice), and 25 PTAs were drained in 25 children without CS.

INTERVENTIONS:

The CS team included an otolaryngologist, a pediatric emergency department physician, and a registered nurse. A standardized CS protocol assessing vital signs and level of consciousness was employed during each procedure. A combination of midazolam, ketamine hydrochloride, and glycopyrrolate was used in appropriately weighted calculated doses. Patients were assessed for major and minor airway complications.

MAIN OUTCOME MEASURES:

Airway complications related to CS were reviewed. Patients who underwent I&D with and without CS were compared with regard to purulent drainage.

RESULTS:

There were no major airway complications in patients undergoing I&D with CS. There was 1 minor complication in this group, oxygen desaturation to 88%, which resolved with stimulation. Of the 55 procedures, 45 (82%) yielded purulence: 29 (97%) of 30 in the CS group and 16 (64%) of 25 in the non-CS group (chi2 = 9.8; P = .002). Of those children undergoing CS, 3 (10%) of 30 were admitted to the hospital from the emergency department as compared with 6 (24%) of 25 without CS (chi2 = 1.95; P = .16). In the CS group, PTAs had a low recurrence rate of 1 (3.3%) of 30 compared with 2 (8%) of 25 in the non-CS group (chi2 = 0.57; P = .45). No one in the CS group required a secondary procedure under general anesthesia.

CONCLUSIONS:

This preliminary study demonstrates CS to be a potentially safe and efficacious approach to drainage of PTAs in children. Given its efficacy and its associated lower levels of anxiety and pain for the patient, CS seems to be a promising new approach to caring for children with PTAs.
