Local or general anesthesia for open hernia repair: a randomized trial.
OBJECTIVE
To compare patient outcome following repair of a primary groin hernia under local (LA) or general anesthesia (GA) in a randomized clinical trial.


BACKGROUND
LA hernia repair is thought to be safer for patients, causes less postoperative pain, cost less, and is associated with a more rapid recovery when compared with the same operation performed under GA.


METHODS
All patients presenting to three surgeons during the study period with a primary groin hernia were considered eligible. Outcome parameters measured including tests of vigilance, divided attention, sustained attention, memory, cognitive function, pain, return to normal activity, and costs.


RESULTS
Two hundred seventy-nine patients were randomized to LA or GA hernia repair; 276 of these had an operation, with 138 participants in each group. At 6, 24, and 72 hours postoperatively there were no differences in vigilance or divided attention between the groups. Similarly, memory, sustained attention, and cognitive function were not impaired in either group. Although physical activity was significantly impaired at 24 hours, this and return to usual social activities were similar in both groups. While patients in the LA group had significantly less pain on moving, at 6 hours they were less likely to recommend the same operation to someone else. GA hernia repair cost 4% more than the same operation under LA.


CONCLUSIONS
There are no major differences in patient recovery after LA or GA hernia repair. Patients should be offered a choice of anesthesia, LA or GA, for repair of their groin hernia.
