Background and Aim: Hypertension is one of the most common comorbidities in cataract surgery and severe hypertension sometimes cause surgery to be postponed. The purpose of this study is to evaluate the relationship between preoperative hypertension and intraoperative hemodynamic changes and postoperative early cardiovascular and cerebral complications on cataract surgery.
Materials and Methods: This study was performed on 160 patients with cataract surgery in Mashhad Khatam-al-anbia hospital. Before induction, the patients were divided into three groups by blood pressure measurement: normotensive (blood pressure <140/90) 100 patients, hypertensive (blood pressure 140/90 to 180/110) 30 patients and hypertensive crisis (blood pressure>180/110) 30 patients. Blood pressure and heart rate were assessed before entering to operating room, before induction and every 5 minutes to the end of surgery, after recovery and ward transfer. Cardiovascular and neurological complications were assessed 24 hours after surgery. Data were analyzed by SPSS software. P<0.05 was considered significant.
Results: There was no significant difference between patients for demographic and preoperative hemodynamic parameters. Preinduction, the blood pressure increased compared to the ward, which was more significant in the hypertensive and hypertensive crisis groups (P=0.001). After induction, systolic blood pressure reduced which was more significant in the hypertensive crisis group than two other groups (P=0.001). The heart rate increased after transferring to the operation room and returned to normal after induction of anesthesia, but in three groups were not statistically significant (P=0.25). Systolic blood pressure < 90 mmHg during the surgery, and also cardiovascular and nervous complications up to 24 hours were not significantly different in three groups (P=0.75 and P=0.08, respectively).
Conclusion: Blood pressure instability was more common in patients with hypertension crisis, but no early or debilitating complications were observed. Primary hemodynamic changes were rapidly reduced and controlled by induction of anesthesia. According to the findings, preinduction blood pressure alone is not sufficient to cancellation of cataract surgery.
