简要总结
Video laryngoscopy provides easily a good laryngeal view compared to direct laryngoscopy. It is particularly, useful in patients with anticipated difficult intubation, and also widely used for educational purposes. Among video laryngoscopy, Mcgrath is a recently-developed, portable video laryngoscopy with a liquid crystal display (LCD) monitor and disposable curved blade.
Mcgrath is known to provide excellent laryngeal visibility even in case of anticipated-difficult and anticipated-unsuccessful intubation as well as normal airway management. However, compared with direct laryngoscopy, the success rate of intubation and the time required for anticipated difficult intubation have been reported conflicting results in previous studies. The aim of this study was to compare the intubation success rate, the intubation time and the ease of use with Mcgrath video laryngoscopy and direct laryngoscopy during intubation.
详细描述
- In the operating room, all patients are monitored with an electrocardiograph, noninvasive blood pressure, pulse oximeter, capnograph and Bispectral index (BIS) monitor. After pre-oxygenation with 100% oxygen for 1 minute, intravenous anesthesia (TIVA) with propofol and remifentanyl is administrated and followed by rocuronium (0.6mg/kg). When patients are lost their consciousness, manual mask ventilation is proceeded with 100% oxygen for 2 minutes.
- Transoral endotracheal intubation is performed using Mcgrath videolaryngoscope (Group ML) and direct laryngoscope (Group DL) using manual in-line stabilization. At this time, the time required for intubation is measure by other medical personnel not engaged in this research.
- The anesthesiologist assesses Cormack Lehane laryngeal visual field,external laryngeal manipulation, intubation difficulty scales (IDS) and the difficulty of intubation.
