Clinical study of adverse effects of different administration methods of lidocaine on recovery period of gen-eral anesthesia in maxillofacial surgery patients with nasal tracheal intubation
Objective To analyze the effects of lidocaine administration through air tube and vein on the recovery period of general anesthesia in patients undergoing nasotracheal intubation in maxillofacial surgery.Method A total of 90 patients with nasotracheal intu-bation in the Maxillofacial surgery Department of Nantong Stomatology Hospital from February to November 2023 were selected and di-vided into three groups according to different administration methods during the recovery period.After surgery,group A(n=30):lido-caine 1mg/kg was injected intravenously;Group B(n=30):lidocaine 1mg/kg was injected through a tracheal catheter;Group C(n=30):No intervention.The effects of sedation and analgesia,hemodynamic changes and coughing were compared among the three groups.Results The recovery time of the three groups was compared(P>0.05).The heart rate and blood pressure of patients in T2(extubation)increased and slowly decreased,and the increase rate of group A and B was lower than that of group C,and group B was the lowest(P<0.05).10 min after extubation,the sedative and analgesic effect of groups A and B was better than that of group C,and the pain score of group B was the lowest(P<0.05).During sputum aspiration and extubation,the coughing rate of groups A and B was lower than that of group C,and the incidence of group B was the lowest(P<0.05).Conclusion In maxillofacial surgery pa-tients with tracheal intubation through the nasal tube,lidocaine has a good sedative and analgesic effect,which is conducive to maintai-ning the stability of hemodynamics and reducing the occurrence of cough.
