EFFECT OF ANESTHEIC AGENT PROPOFOL ON CARDIOVASCULAR STABILITY OF HYPERTENSIVE PATIENTS UNDERGOING APPENDECTOMY
Abstract
Hypotension and cardiac depression have long been termed hemodynamic adverse effects of propofol, a widely used intravenous anesthetic. Patients with hypertension are more likely to have perioperative cardiovascular instability with their compromised vascular autoregulation. This group is important to know how propofol influences hemodynamic parameters to be able to improve the anesthetic therapy and patient outcomes.
Objective(s)
Examining the effects of propofol on cardiovascular stability in hypertensive individuals undergoing appendiceal excision is the aim of this study. The primary objective is to evaluate changes in heart rate, blood pressure, and cardiac output following propofol induction.
Secondary objectives include determining the factors influencing hemodynamic fluctuations and if vasopressor assistance is required.
Methodology
A prospective observational experiment was conducted with hypertensive patients scheduled for elective appendectomy. As part of the patients' standardized anesthetic regimen, propofol was used for induction. Hemodynamic measurements, including heart rate, mean arterial pressure (MAP), and systolic and diastolic blood pressure, were taken at baseline, during induction, and throughout surgery. The prevalence of hypotension (MAP < 65 mmHg) and the requirement for vasopressors were analyzed. The data was statistically examined using appropriate procedures, including the ANOVA and the paired t-test.
Results
Preliminary findings indicate that propofol induction causes a considerable reduction in blood pressure, with hypertension patients seeing a greater drop in MAP than normotensive controls. The degree of hypotension was correlated with baseline blood pressure and the usage of antihypertensive medications prior to surgery. In order to stabilize individuals with poorly controlled hypertension, vasopressor doses have to be raised. Despite the short hypotension, no serious adverse cardiac events were seen.
Conclusion(s)
When hypertensive patients have an appendectomy, propofol induction causes a noticeable but controllable drop in blood pressure. Cardiovascular stability can be preserved by carefully titrating propofol, optimizing blood pressure prior to surgery, and providing early vasopressor therapy. Comparing different anesthetic drugs in this population requires more research.
