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.

BACKGROUND:Static compressure effect between the fracture fragments was generated by fixation itself (tension band wire and screw), but dynamic compression effects were generated during flexion. Mechanical strength and stability of patel ar fracture fixation have obvious advantages. However, there are lacks of quantitative comparative studies on static and dynamic compression effects of these fixation methods.
OBJECTIVE:To observe strength changes and clinical significance of static and dynamic compression using four fixation techniques.
METHODS:Standardized transverse patel ar fracture models were created with fresh cow patel as. The patel as were randomly divided into four groups:fixation was accomplished with modified tension band wiring (wire group);modified tension band with braided cable (cable group);interfragmentary screws (screw group);cannulated screw tension band with wire (cannulated screw group). Before fracture fixation, Fuji pressure-sensitive film was laid among fracture fragments to measure the pressure among fracture fragments after fixation, i.e., static and dynamic compression. Model of each group was measured as fol ows:(1) after fixation, the fixation was removed, and the Fuji pressure-sensitive film was taken out;(2) after fixation, material testing machine was used. Samples underwent a three-point bending test with a 5 000 N load, simulating dynamic compression during knee flexion. Subsequently, Fuji pressure-sensitive film was taken out. Each Fuji pressure-sensitive film was tested using prescale FPD-8010E software. Thus, average pressure among broken bone ends was obtained, and statistical analysis was performed. Static and dynamic compression among broken bone ends was compared in each group.
RESULTS AND CONCLUSION:Average static compression was significantly lower in the wire group than in the cable group, screw group and cannulated screw group (P<0.05). Under 5 000 N load of dynamic compression, similar compression among broken bone ends was visible among wire group and cable group, screw group and cannulated screw group (P>0.05). Dynamic compression was higher than static compression in the wire group (P<0.05). Results verified that compared with modified tension band wire fixation technique, cable or screw could evidently increase static compression among broken bone ends, but simultaneously weaken dynamic compression among broken bone ends.
