Abstract:

Objective    To evaluate the feasibility and efficiency of the intraoperative wake-up test for strabismus surgery in teenagers. Methods    All 136 cases underwent general anesthesia and were divided into 2 groups. The first group had general anesthesia with intra-operative wakeup test, and the other had general anesthesia without the test. In the first group, operated muscles were first tightened with a slipknot. Then, the patient was awakened to examine the eye position. If the position was orthoptic, the suture was securely tied. Otherwise, general anesthesia was reinstalled and  the surgical procedures were repeated until the orthoptic position was achieved. The other group underwent surgery under general anesthesia with ketamine according to the preoperative assessment.  Results    (1)70 cases received intraoperative wake-up test. Among them, 65 reached orthoptic position when awakened while the procedures were repeated again in the other 5 cases to achieve the goal. (2)The success rate of the group with intra-operative wake-up test was 100% 1 week after the operation, which was significantly higher than the other group (92.4%, P=0.019). One year after the operation, the success rates of surgery in patients with and without intra-operative wake-up test were 93.7% and 87.1%, respectively. There was no significant difference among the two groups (P=0.214). Conclusion    General anesthesia with intra-operative wake-up test not only alleviates the pain of teenager in strabismus surgery, but also improvesthe success rate.
