Study On The Feasibility And Superiority Of Laryngeal Mask Applied In The Anesthesia Of Burn Patients

Background:To investigate the safety and superiority of laryngeal mask and tracheal intubation in the anesthesia of burn operation.Method:40 cases of adult burn patients?ASA I^III level?were randomly divided into laryngeal mask group?A group?and tracheal intubation group?B group?2 group,20 cases in each group.Both groups were treated with sufentanil 0.2ug/kg,midazolam 0.06mg/kg,propofol 1.0².0mg/kg,and cisatracurium 0.2mg/kg induction,after the drug is fully effective,the A group is placed into the laryngeal mask and B group tracheal intubation.Intraoperative infusion of propofol3⁸mg/?kg.h?and remifentanil 6¹0ug/?kg.h?maintained,and inhaled 1%²%seven halothane,intermittent giving of cisatracurium to maintain muscle relaxation,the value of BIS in 40⁶0 in maintenance operation.The groups of patients were recordedmeanarterialpressure?MAP?,hiartrate?HR?,pulseoxygen saturation?SpO₂?,partial pressure of carbon dioxide in endexpiratory gas(P_ETCO₂),peak pressure?Ppeak?,and plateau pressure?Pplat?at 7 time points:after entering the operating room?T₀?,before intubation?T₁?,intubation immediately?T₂?,3min?T₃?after intubation,5min?T₄?after laryngeal mask insertion or endotracheal intubation intubation,before extubation?T₅?,and extubation immediately?T₆?.The venous blood was extracted from the T₀,T₁,T₂,T₃ and T₄,and the concentration of blood glucose?Glu?and serum cortisol?Cor?was measured.The postoperative complications such as wake delay,laryngeal spasm,nausea and vomiting and restlessness in the wake period of each group were compared.The pain score?VAS score?was performed on the patient 5min?T₇?,4h?T₈?and 24h?T₉?after extubation.Result:There was no statistically significant difference in preoperative and intubation indexes between the two groups?P>0.05?.While after the laryngeal mask/tracheal catheter was placed and removed,group B HR,MAP,Ppeak,Pplat,Glu and Cor were significantly higher than those in group A?p<0.05?.Postoperative VAS score,group B was still significantly higher than group A?p<0.05?.However,there was no significant difference?p>0.05?between SpO₂,P_ETCO₂ and group in all time points.Conclution:The laryngeal mask is less stimulating for burn patients,the stress response is lighter,the hemodynamic effect is smaller,and the symptom of postoperative sore throat is reduced obviously,which is helpful to maintain the stable vital signs,protect the patients'airway and postoperative rehabilitation,and it is more advantageous to burn patients clinically.
