The risk of postoperative haemorrhage in tonsillectomy as an outpatient procedure in children.

The safety of performing tonsillectomy as an outpatient procedure is still questionable. This study determined whether there was an increased risk of postoperative bleeding by performing tonsillectomy as an outpatient procedure. A six years' retrospective chart review was made of 363 children who underwent tonsillectomy. Out of 363 children, 43 had been selected as an inpatient group before the operation, 264 patients were discharged home 6 h after the operation and were the outpatient group, and 56 children had to be kept overnight because of complications that had occurred. We compared the haemorrhage rate in the outpatient and the inpatient groups. We found no increase in the postoperative haemorrhage rate in the outpatient group. No statistically significant correlations were found between the children's ages, indication for surgery, type of operation or intra-operative complications and the risk of postoperative haemorrhage. Only children who had haemorrhage in the recovery room were identified as a high risk subgroup for recurrent bleeding. On the basis of our findings we believe that tonsillectomy can be performed as an outpatient procedure regardless of age, indication for surgery, or type of procedure, as long as good recovery room supervision exists for 4 to 6 h.
