A comparison of postoperative bleeding incidence between general and local anesthesia tonsillectomies

Postoperative bleeding after tonsillectomy is a problem that has earned the respect and cautious attention of the most experienced surgeons. The incidence of postoperative hemorrhage after tonsillectomy, as well as many factors affecting this incidence, has been extensively investigated. A possible factor that has not been well studied as a possible influence in postoperative tonsillectomy bleeding is the choice of anesthetic. A study was completed comparing the incidence of postoperative tonsillectomy bleeding between patients operated on using general anesthetic and local anesthetic. One hundred ninety-two patients consecutively undergoing tonsillectomy at Naval Hospital, Oakland, California, were included in the study. Three of 150 patients (3%) having general anesthesia and 13 of 87 patients (15%) having local anesthesia experienced postoperative bleeding. Possible factors influencing this difference in postoperative bleeding incidence are discussed. The possibility is suggested that surgeons (and previous reports) may underestimate the rates of postoperative bleeding as a result of patients being treated by other than the operating physician.
