Abstract:
Objective To compare the GlideScope video-laryngoscope and Macintosh laryngoscope for double-lumen tube (DLT) intubation.Methods Seventy ASA Ⅰ-Ⅲ patients,aged 18-75 yr,scheduled for thoracic surgery and requiring one-lung ventilation,were randomly divided into 2 groups (n =35 each):Macintosh laryngoscope group (group M) and GlideScope video-laryngoscope group (group G).Anesthesia was induced with propofol,fentanyl and rocuronium.The exposure of glottis obtained with Macintosh laryngoscope and GlideScope video-laryngoscope was assessed using Cormack-Lehane grade.DLT intubation was assisted with Macintosh laryngoscope or GlideScope video-laryngoscope.The Cormack-Lehane grade,difficulty of DLT placement,and reverse DLT placement were recorded.The success rate of DLT placement at first attempt and intubation time were also recorded.Blood pressure and heart rate were recorded before intubation and at 0 and 3 min after intubation.The postoperative side effects were recorded.Results Compared with M group,the intubation time was significantly prolonged,the difficulty of DLT placement and blood pressure at 0 and 3 min after intubation were increased in G group (P ＜ 0.05).There was no significant difference in the success rate of DLT placement at first attempt,rate of reverse DLT placement,Comark-Lehene grade and heart rate at each time point between the two groups (P ＞0.05).The Comark-Lehene grade obtained with GlideScope video-laryngoscope was superior to that obtained with Macintosh laryngoscope in G group (P ＜ 0.05).Conclusion GlideScope video-laryngoscope can provide a better exposure of glottis and improvement in the intubating conditions,but the method is more complex and the response to intubation is stronger than Macintosh laryngoscope for DLT intubation.
