Abstract

Purpose: To determine and compare the incidence of postoperative nausea and vomiting in patients having phacoemulsification under topical or retrobulbar anesthesia.

Setting: Department of Ophthalmology, United Christian Hospital, Hong Kong, China.

Methods: In this prospective randomized clinical trial, patients scheduled for routine phacoemulsification with posterior chamber intraocular lens implantation under local anesthesia without sedation were randomized to receive topical anesthesia or retrobulbar anesthesia. One hundred seven eyes of 107 Chinese patients were included. There were 49 patients and 58 patients of similar age and sex distribution in the retrobulbar group and topical group, respectively. Postoperative nausea and vomiting (PONV), the need for an antiemetic, and intraocular pressure (IOP) were recorded 1 day after surgery. Also recorded were the patient's preexisting risk factors for PONV (if any), fasting time, duration of surgery, and intraoperative complications or need for supplementary anesthesia or analgesia.

Results: The overall incidence of PONV in the entire study group was 3.7% (4 patients). No statistically significant differences in PONV were found between the 2 anesthesia techniques, although 6.1% (3 of 49) in the topical group had nausea compared with 1.7% (1 of 58) in the retrobulbar group. No significant differences were found in the fasting time, duration of surgery, or postoperative IOP between patients who had PONV and those who did not.

Conclusions: Topical and retrobulbar anesthesia were associated with a low incidence of PONV in routine phacoemulsification. There were no statistically significant differences in PONV between the 2 anesthesia techniques. No significant correlation was found between the incidence of PONV and the duration of surgery, presence of complications, fasting time, postoperative IOP, or history of PONV or motion sickness.
