Application of sevoflurane intravenous inhalational anesthesia and remifentanil intravenous anesthesia for single lung ventilation in the department of thoracic surgery operation

Abstract

Objective To investigate the effect of sevoflurane intravenous inhalational anesthesia and remifentanil intravenous anesthesia for single lung ventilation in the department of thoracic surgery operation. Methods 80 patients using thoracic surgery were randomly divided into the two groups with 40 cases in each group according to the number table methods, the study group were treated with sevoflurane inhalation anesthesia while the control group were treated with remifentanil intravenous anesthesia. HR,MAP and SBP of the two groups before induction of anesthesia(T0),1min before intubation(T1),10min after ventilation(T2),30min after ventilation(T3)and 1min before extubation(T4) were compared, and recovery time, extubation time, directional force the recovery time were recorded of the two group. Results The HR in the two groups at T 1,T2,T 3,T 4 time did not change significantly than T0 time,while MAP decreased significantly than T0 time,with significant difference(t= 8.12,7.82,8.14,8.05,all P 0.05);The SBP in the study group did not change obviously at each time while the SBP in the control group at T1 decreased significantly than T0 time,while it increased significantly at T2 time than T1 time,with a significant difference(t= 10.51,5.34,5.05,5.06,all P< 0.05);The patients in study group were elevated blood pressure during anesthesia or decreased more than 30% occurred in 8 cases while the control group occurred in 24 cases,there was significant differences between the two groups(χ2= 13.33,P<0.05);The postoperative recovery time,extubation time and orientation recovery time of the study group patients were(11.4±5.1)min,(13.4±6.8)min,(18.9± 5.8)min,which were significantly lower than(19.5±5.2)min,(26.5±7.6)min,(21.9±7.8)min of the control group(t= 5.34,6.12,6.15,all P< 0.05). Conclusion Sevoflurane intravenous inhalational anesthesia has a better anesthetic effect for single lung ventilation in the department of thoracic surgery operation than remifentanil intravenous anesthesia, and it can effectively maintain hemodynamics stability.
