Conditions
Brief summary
In difficult intubation cases, the guidelines provide recommendations for advanced airway equipment availability, and neuraxial anesthesia is encouraged. Our aim is to compare the McGrath video laryngoscope (VL) and the Macintosh direct laryngoscope (DL) according to the intubation time and glottic visualization in patients undergoing cesarean sections. Patients undergoing cesarean sections under general anesthesia will be included in this research. This study has a prospective design, and the patients will be randomized using a sealed envelope technique into 2 groups using either the Macintosh DL or the McGrath VL. During intubation, the times to obtaining a glottic view, tracheal tube placement, and confirming tracheal intubation as confirmed by CO2 waveform observation will be recorded. The mean arterial pressures and heart rates before intubation and after intubation will also be recorded. The mean tests will be compared using an independent t test if the data distribution are normal, or a nonparametric Mann-Whitney U test if the data are not distributed normally. A p value < 0.05 will be considered to be statistically significant.
Interventions
In this study we are using an airway approach for patients undergoing cesarean section under general anesthesia. After the patient arrive in the OR, the ASA standard monitoring procedures will be applied. All the patients will receive standard general anesthetic regimens, which include propofol [intravenous (IV), 1–2 mg/kg titrations] and rocuronium bromide (IV, 0.6 mg/kg). The timing measurements will begin once the McGrath video laryngoscope blade will be placed in 1 or 2 seconds in the patien

The timing measurements will begin once the McGrath video laryngoscope blade will be placed in 1 or 2 seconds in the patient’s mouth by the attending researcher anesthesiologist, and they will end when an end-tidal CO2 trace will be detected on the direct supervision by researcher. The attending anesthesiologist will rate the glottic visualization as the tracheal tube being inserted using the Cormack-Lehane classification system and the percentage of glottic opening (POGO)
