RESUMO
Objective To compare the effect and safety between lightwand and general-laryngo-scope application of trachea cannula in cervical spine fracture patients undergoing general anesthesia. Methods Forty cervical spine fracture patients with tracheal intubation anesthesia were selected,including twenty-eight males and twelve females,aged 18-65 years,ASA physical statusⅡor Ⅲ.These patients were randomly divided into two groups,twenty cases in each group.After anesthesia induction,group L was giv-en general laryngoscope intubation,whereas group C was taken lightwand guided tracheal intubation.The success case of intubation at first,intubation time,adverse reaction of intubation,changes of MAP and HR at intubation and 5 minutes after intubation were observed.Results Compared with group L,success rate of intubation at first was higher (90% vs.60%),intubation time was shorter [(31.3±11.1)s vs.(46.6 ±15.2)s]in group C (P <0.05).The changes of MAP and HR were more stable during intubation in group C compared with group L.Four cases of arrhythmia (20%)occurred in group C,while none in group L.Conclusion Compared with intubation by general laryngoscope,application of tracheal intubation led by lightwand in cervical fracture patients is more effective and safer.
