Application Of General Anesthesia Without Muscle Relaxant Combined With Right Stellate Ganglion Block On Patients Undergoing Oropharyngeal Surgery

Objective To observe the efficacy of tracheal intubation without muscle relaxant combined with right stellate ganglion block on patients undergoing oropharyngeal surgery.Methods 60 patients undergoing selective oropharyngeal surgery were randomly divided into 2 groups?n=30 each?,One was control group:Anesthesia was induced with inhalation of sevoflurane and remifentanil given by TCI.The other was nerve block group:Anesthesia was induced with inhalation of sevoflurane and remifentanil given by TCI,and right stellate ganglion block was performed 10 minutes before anesthesia induction,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?.And consciousness recovery time,the endotracheal extubation time and OAA/S scores were recorded.The VAS score at 4,8,12,24h after surgery were also recorded.Results All patients were successfully intubated at first attempt.The difference of the satisfactory intubation conditions was not statistically significant?P>0.05?.MAP and HR were increased at T₂ and T₃ as compared with control group?P<0.05?,MAP and HR remained stable before and after tracheal intubation in nerve block group,Compared with nerve block group,HR increased at T₂ and T₃ in control group?P<0.05?.There are no significant differences between the two groups of consciousness recovery time and endotracheal extubation time.The VAS of patients in nerve block group was lower than control group?P<0.05?.Conclusion Right stellate ganglion block on patients undergoing oropharyngeal surgery in general anesthesia without muscle relaxant might provide not only an available intubation conditions but also provoke earlier recovery and improve the quality of postoperartive analgesia.
