Abstract:
Objective To evaluate the value of Disposcope-guided the left-sided double-lumen tube (DLT) intubation.Methods Fifty ASA physical status Ⅰ or Ⅱ patients,aged 47-69 yr,without difficult airway,scheduled for elective thoracic surgery,were randomly divided into 2 groups (n =25 each) using a random number table:Disposcope (group D) and Macintosh direct laryngoscope (group M).Anesthesia was induced with iv injection of midazolam,propofol,sufentanil and rocuronium.Before induction (baseline,T1),before intubation (T2),immediately after successful intubation (T3),and at 1 and 3 min after intubation (T4-5),systolic blood pressure (SBP),mean airway pressure (MAP) and heart rate (HR) were recorded,and rate-pressure (SBP) product (RPP) was calculated.Arterial blood samples were obtained at T1-5 for measurement of plasma epinephrine (E),norepinephrine (NE),and dopamine (DOPA) concentrations.The success rate of DLT intubation at first attempt,total success rate of DLT intubation,intubation time,and development of sore throat within 24 h after surgery were recorded.Results Compared with group M,the intubation time was significantly shortened,the success rate of DLT intubation at first attempt was increased,the incidence of sore throat was decreased,and the levels of MAP,HR,RPP,E,NE and DOPA were decreased at T3-5 in D group (P ＜ 0.05).Compared with the baseline value at T1,the levels of MAP,HR,RPP,E,NE and DOPA were decreased at T3-5 in M group (P ＜ 0.05),and no significant change was found in D group (P ＞ 0.05).Conclusion Disposcope-guided left-sided DLT intubation provides significant clinical value.
