Other post-operative events and mortality
Post-operative bleeding especially amongst those who had a concurrent tonsillectomy has been reported in all the studies except one (13). It was the most reported non-respiratory event (53/1750, 3.0%) and tended to occur following discharge regardless of being performed as a day case or inpatient group. Post-operative pain and/or dehydration were also common post-operative events reported (6, 10, 14). Other complications reported were sinus bradycardia (16), hypertension (8, 11) with some patients requiring IV labelatol, and urinary retention (11, 12).
None of the studies had any mortality documented within the follow-up period. The length of follow-up varied from seven days to 30 days. Two studies did not specify a length of follow-up (11, 12).
