目的:研制一种主要应用于院前急救气管插管的自身携带光源的光导气管导管并探讨其临床应用价值。方法:采用镶嵌技术将光导纤维植入导管管壁内,在管体连接头下侧设置光浦,光浦、分光器、光导纤维、聚光器相邻依次连接并与管体固为一体,使光浦发出的光能传递照明前方气道。将该导管随机应用于院前急救气管插管63例,与应用普通气管导管插管87例对照,观察2组的一次插管成功率、平均插管时间。结果:实验组的一次插管成功59例,成功率为93.65%,平均插管时间(11.53±0.62)s;对照组一次插管成功62例,成功率为71.26%,平均插管时间(13.72±0.55)s。分别比较2组同性指标,差异均有统计学意义(P<0.01)。结论:该新型气管导管性能优于普通气管导管,适合在院前急救中推广应用。
OBJECTIVE: To develop a light-guiding tracheal catheter with its own light source which is mainly used in pre-hospital emergency tracheal intubation and to explore its clinical value. Methods: The optical fiber was implanted into the catheter wall by inlaying technique. The optical pump, the optical pump, the optical splitter, the optical fiber and the optical condenser were arranged on the lower side of the connector. The light emitted can transmit the airway in front of the light. The catheter was randomly applied to the hospital before the emergency tracheal intubation in 63 cases, and the application of common endotracheal tube 87 cases of control, the two groups observed a success rate of intubation, the average intubation time. Results: The success rate of primary intubation was 59.65% in the experimental group, and the average intubation time was 11.53 ± 0.62 s. In the control group, 62 cases were successfully intubated, the success rate was 71.26%, the average intubation time was 13.72 ± 0.55) s. The two groups of same-sex indicators were compared, the differences were statistically significant (P <0.01). Conclusion: This new type of endotracheal tube is better than common endotracheal tube, which is suitable for popularization and application in prehospital emergency.
