| Popis: | Background The purpose of study was to compare the changes in blood pressure in patients undergoing phacoemulsification cataract surgery under topical and peribulbar anaesthesia during preoperative, intraoperative and postoperative period. Methods In this prospective cohort study, 240 patients undergoing phacoemulsification were divided into topical (Group 1) and peribulbar (Group 2) equally. Proparacaine 0.5% drops were used for topical anaesthesia, and Inj lignocaine with Inj bupivacaine were used to give peribulbar anaesthesia. Preoperative blood pressure was taken 30 min before surgery with automated sphygmomanometer. Intraoperative blood pressure was taken during phacoemulsification, and postoperative blood pressure was taken 1 h after surgery. Outcomes assessed were systolic, diastolic and mean blood pressure. Results Systolic blood pressure in Group 1 was significantly increased in the intraoperative phase, whereas it was significantly decreased in Group 2 in the intraoperative phase. Diastolic and mean blood pressure in Group 1 showed no significant change, whereas in Group 2, both showed significant reduction in intraoperative and postoperative phases. Conclusion The increase in intraoperative systolic blood pressure in topical group could be due to discomfort from microscope light, iris manipulation, irrigation and aspiration during surgery. The decrease in intraoperative systolic and diastolic blood pressure in peribulbar group could be due to systemic absorption of local anaesthetic. The mean preoperative systolic blood pressure was also higher in the topical group, which could be due to anxiety or stress under topical anaesthesia. The changes in blood pressure need to be observed so that timely intervention can be made to achieve favourable postoperative outcome. |
