Abstract
ObjectiveTo observe the efficacy of sub-Tenon’s retrobulbar anesthesia in scleral buckling surgery.
MethodsThe data of 62 eyes of 62 patients who underwent scleral buckling surgery were randomly divided into two groups. Group A, 32 eyes of 32 cases, received sub-Tenon’s retrobulbar anesthesia ; group B, 30 eyes of 30 cases, underwent classical retrobulbal anesthesia. The degrees of pain were evaluated by visual analogue pain scale(VAPS) at different time points. The akinesia of eye was evaluated by akinesia score at different time points. Degree of satisfaction of surgeon and complications of anesthesia were observed and recorded.
ResultsThe difference of degree of pain between the two groups was statistically significant at 30 s, 1 min, 2 min after anesthesia and during operation(P<0.05). The degree of pain of group A was lesser than that of group B. The difference was not statistically significant at 3 min, 4 min and 5 min after anesthesia between the two groups(P>0.05). The difference of akinesia score between the two groups was statistically significant at 30 s, 1 min, 2 min, 3 min and during operation(P<0.05) and akinesia score of group A was better than that of group B. The difference was not statistically significant at 4 min and 5 min after anesthesia (P>0.05). The degree of satisfaction of group A was better than that of group B, the difference was statistically significant(P<0.05). There were chemosis and subconjunctival hemorrhage in 9 cases (28.1%) of group A and 5 cases (19.8%) of group B. There was retrobulbar hemorrhage in 1 case (3.1%) of group A and 2 cases (6.6%) of group B. The difference of complication was not statistically significant(P>0.05). No amaurosis or oculocardiac reflex happened.
ConclusionSub-Tenon’s retrobulbar anesthesia can provide faster analgesic effect and better satisfication, and it is a safe and effective anesthesia method.
