UNASSIGNED
The aim of this study was to compare anesthetic and surgical outcomes of external dacryocystorhinostomy (DCR) under loco-regional anesthesia (LA) versus general anesthesia (GA).
UNASSIGNED
Retrospective chart review of all patients that underwent DCR by one surgeon (IH) over the course of a ten-year period (April 1994 to March 2003).
UNASSIGNED
A total of 221 DCR were performed on 209 patients during the study period: 71 were done under LA (72.0 ± 13.3 years) and 150 under GA (64.2 ± 13.0 years; P<0.001). LA patients had a shorter length of surgery (56.2 ± 15.3 vs. 64.0 ± 18.1 minutes; P=0.001) and required less antiemetic drugs during the first four hours after surgery (P=0.03). Pain was well controlled and patients were comfortable per- and post-operatively. Excluding ecchymosis (38.0% LA vs. 21.6% GA; P=0.01), the rate of minor complications did not differ between the two groups: infection, inflammation or edema (14.1 vs. 18.2%; P=0.13), hematoma (1.4 vs. 2.7%; P=0.52) and epistaxis (22.5 vs. 14.2%; P=0.44). Rates of recurrent symptoms and/or re-intervention (11.3 vs. 13.1%; P=0.91) were comparable for LA and GA.
UNASSIGNED
This study suggests that external DCR performed under LA and monitored anesthesia care may be advantageous. The length of surgery is reduced, post-operative side effects are diminished, and excluding ecchymosis, the rate of minor complications is not increased. These benefits are desirable in a predominantly elderly population where avoidance of GA risks is at times necessary.
