BACKGROUND: Changes are observed in blood pressure (BP) levels during cataract surgery, although BPs are considered to remain stable under local anesthesia. We evaluated the daily, pre- and postoperative BPs of 2270 patients after cataract surgery performed under either topical anesthesia or retrobulbar block.
METHODS: All operations were performed by the same surgeon using the same method of phacoemulsification and aspiration with posterior chamber intraocular lens implantation under local anesthesia.
RESULTS: The mean daily BP was 99.3 +/- 14.2 mm Hg; the mean preoperative BPs increased and then the postoperative BPs decreased. The postoperative BPs of the retrobulbar injection group decreased significantly more than those of the topical application group. In 833 cases, the systolic BP changed by more than 20 mm Hg. Even when the patients were hypertensive, the preoperative and postoperative BPs decreased in the same manner.
CONCLUSION: The present study shows that, following surgery with retrobulbar block anesthesia, BP decreases to a greater extent than with topical anesthesia. Physicians should be aware of the high proportion of cases in which the systolic BP changes by more than 20 mm Hg.
