Application of general anesthesia without muscle relaxant conbined with right stellate ganglion block on patients undergoing oropharyngeal surgery / 安徽医科大学学报

ABSTRACT

To observe the feasibility and safety of general anesthesia without muscle relaxant tracheal intubation combined with right stellate ganglion block (SGB) on patients undergoing oropharyngeal surgery.60 patients undergoing selective oropharyngeal surgery were randomly and equally divided into 2 groupsnamed in non muscle relaxation group and combination group.MAP,HR,SpO2 and PETCO2 were recorded before administration (T0),immediately before tracheal intubation(T1),and immediately after tracheal intubation(T2),and immediately after skin incision (T3).The VAS score at 4,8,12,24 h after surgery were also recorded.The difference of the satisfactory intubation conditions was not statistically significant.MAP and HR were increased at T2 and T3 as compared with non muscle relaxation group.Compared with combination group,HR increased at T2 and T3 in group A.The VAS of patients in combination group was lower than non muscle relaxation group (P ＜ 0.05).Stellate ganglion block on patients undergoing oropharyngeal surgery in general anesthesia without muscle relaxant might provide not only satisfactory intubation conditions but also provoke earlier recovery and improve the quality of postoperartive analgesia.
