Clinical application of Disposcope endoscope in Univent tube intubation and positioning / 临床麻醉学杂志

ABSTRACT

Objective To observe the clinical application effects of Disposcope endoscope in Univent tube intubation and positioning.Methods Eighty patients underwent scheduled thoracic sur gery (51 males,29 females,aged 18-77 years,ASA Ⅰ-Ⅲ) under one-lung ventilation (OLV) were randomly grouped into two groupsDisposcope endoscope group (group D) and laryngoscope group (group L),40 patients in each group.Group D used Disposcope endoscope for intubation and positio ning while group L used laryngoscope for intubation and auscultation positioning.Patients with difficult intubation,severe ventilation dysfunction and large sputum volume,such as pulmonary hemoptysis and bronchiectasis,were excluded.Intubation and positioning time,airway pressure and arterial carbon dioxide partial pressure (PaCO2) were recorded during double-lung ventilation and OLV,lung collapse effect,and one-time successful intubation ratio,positionging adjustment ratio and the incidence of intubation complications were calculated.Results Intubation and positioning time were significantly longer in group L than in group D [(169.98±52.65)s vs.(102.38±44.45)s](P＜0.05),one-time successful intubation ratio in group L was lower than that in group D (80％ vs.97.5％) (P ＜0.05).The difference of airway pressure and PaCO2 during double-lung ventilation and OLV between the two groups were not statistically significant.The blocker positioning adjust ratio of Univent tube in group L was significantly higher than that in group D (22.5％ vs.7.5％)(P＜0.05).The incidence of bleeding and sore throat after operation in group L were significantly higher than those in group D (27.5％ vs.7.5％,37.5％ vs.15％) (P＜0.05).Conclusion Compare with laryngoscope for intubation and auscultation positioning,Disposcope endoscope used for Univent tube intubation and positioning needs shorter time for intubation and positioning,higher successful one-time intubation ratio,less positioning adjustment.It also reduces the incidence of intubation complications.
