Management of preoperative hypertension and anxiety based on early monitoring of pulse rate before cataract surgery.

Abstract

Purpose: Few studies have addressed the clinical impact of fluctuation in pulse rate before cataract surgery. This study aimed to determine the effectiveness of prior pulse monitoring and intervention to prevent blood pressure changes in patients undergoing cataract surgery under local anesthesia.

Study design: Retrospective study METHODS: Patients who underwent cataract surgery under local anesthesia were included. In the pulse rate (PR) group, intervention was performed on the basis of early monitoring of blood pressure and PR changes. In the conventional group, blood pressure was managed on the basis of blood pressure alone. Systolic blood pressure, diastolic blood pressure, intraoperative nicardipine use, and physician consultation time were retrospectively compared between the groups.

Results: The study included 684 eyes from 684 patients aged 73.5 ± 9.5 years (PR group: 297 eyes, conventional group: 387 eyes). No intergroup differences were found in systolic blood pressure or pulse and heart rates; however, diastolic blood pressure was significantly lower in the PR group than in the conventional group at both the beginning and the end of surgery (P <.001 and P = .0028, respectively). Intravenous nicardipine administration in the operating room was significantly less frequent in the PR group (P = .041), and physician consultation time after entering the operating room and at the beginning of surgery was significantly shorter in the PR group (both P <.001).

Conclusion: Early monitoring of PR with blood pressure and intervention were effective for preventing preoperative hypertension.
