Computerised dynamic posturography to assess recovery comparing general anaesthesia with sedation and local anaesthesia for day case nasal surgery

Computerised dynamic posturography (CDP) can be used as an early marker of recovery to street fitness in patients undergoing ambulatory surgery. We studied three groups of patients undergoing nasal surgery. The goal of this study was to determine whether recovery, as assessed by CDP, is more rapid in patients having nasal surgery under sedation coupled with local anaesthesia or those having surgery under general anaesthesia. We further assessed the acceptability of sedation accompanied by local anaesthesia. A control group was included to determine if there is a learning curve to posturography. There was no difference between the two study groups in terms of balance. Balance was not significantly impaired at 3 h postoperative testing.
