Abstract: (5350 Views)
Background: Sinus surgeries are usually associated with bleeding, thus can result in
hemodynamic instability. This study investigated the hemodynamic changes induced by remifentanil plus isoflurane administration in comparison with
propofol plus remifentanil in patients undergoing sinus surgery.
Methods: In this randomized clinical trial study, 96 patients were divided into two groups of isoflurane (1.2 MAC) plus remifentanil (44 patients, group A) and propofol (100 μg/kg/min) plus remifentanil (52 patients, group B). Twenty-two patients in group A and 23 in group B were male. The remifentanil dosage (0.1 μg/kg/min) was equal in both groups and all received 500 ml isotonic solution during the operation too. Premedications and anesthetic inductions of both groups were similar. The variables included age, BMI, blood loss during surgery, systolic and diastolic blood pressures, pulse rate and mean arterial blood pressure.
Results: The mean age, BMI, amount of blood loss, mean systolic (30 minutes before and after the intervention) and diastolic blood pressures (60 minutes before and after the intervention), pulse rate (30 and 60 minutes before and after the intervention), mean arterial blood pressure (60 minutes before and after the intervention) were similar in both groups. The average mean arterial blood pressure, 30 minutes after the intervention (p=0.027) and the mean diastolic blood pressure, 30 minutes after the intervention (p=0.011) in the case group had statistically significant differences with the controls.
Conclusion: Based on this study, the combination of isoflurane plus remifentanil could better maintain the hemodynamic stability during sinus surgeries.
