Objective:To evaluate the effect of combined administration of different doses of propofol and remifentanil for intravenous anesthesia in patients undergoing endoscopic variceal sclerotherapy(EVS), and/or endoscopic variceal ligation(EVL). Methods:Group A included 30 patients with non-esophageal varices injected with propofol and low-dose remifentanil under gastroscope. Sixty patients with esophageal varices were divided into group B and group C who performed EVS, and/or EVL. Group B was injected with remifentanil and low-dose propofol, while Group C propofol and low-dose Remifentanil. Systolic blood pressure(SBP), diastolic blood pressure(DBP), heart rate(HR) and blood oxygen saturation(SpO2) were recorded at the time before anesthesia induction (T0), the time after anesthesia induction(T1), the time of early stage in therapy(T2), the time of later stage in therapy(T3), 5 minutes after therapy(T4). The amount of anesthetics, the amount of booster, the times of patient's body movement, the level of patient satisfaction, the patient recovery time, and the postoperative complications of the three groups were recorded simultaneously. Results:Compared with T0, SBP, DBP and HR reduced at T1, T2, T3 in all the three groups. Compared with Group A and Group B, SBP, DBP and HR reduced at T1, T2, T3 in Group C. At the same time, the anesthetics dosage of group C was less than that of group A, the booster dosage was more than that of group A and group B, the recovery interval of group C was longer than group A and group B (P<0.05), the number of body movements of group B was higher than that in group A and group C. Conclusion:Combined administration of propofol and remifentanil can better treat esophageal varices under gastroscope, but the use of propofol combined with low-dose of remifentanil has a great influence on the perioperative blood pressure of patients with esophageal varices, and vasoactive drugs should be used to maintain the stability of hemodynamic. |
