Clinical Trial Summary

The aim of this work is to investigate the feasibility of using the modified a ramped position for intubation of obese females in comparison to the traditional ramped position.


Clinical Trial Description

Adequate conditions for endotracheal intubation require appropriate positioning of head and neck. The sniffing position had been described as the most appropriate head position for endotracheal intubation. Sniffing position is achieved through two main components: flexion of the neck by 35° (achieved by head elevation) and extension of the head by 15° 2 to have the sternum at the same level of external auditory meatus 34. Sniffing position has the advantage of alignment of the three axes: oral, pharyngeal, and laryngeal axes for reaching the optimal laryngeal visualization.

In obese patients, it is recommended to put the patient in the ramped position (back-up position with the tragus of the ear is at the level of the suprasternal notch) in addition to the sniffing head-and-neck position. Some commercially available pillows were introduced to facilitate laryngoscopy in obese patients such as: Troop elevation pillow and Rapid airway management positioner.

In addition to difficult laryngeal visualization, another problem commonly confronts anesthetists during intubation of obese females; that is impedance of laryngoscopy by large breasts. This problem commonly hinders the intubation process and might lead to serious hypoxia. Most of the positions described in literature were concerned with facilitating laryngeal visualization. No position to the best of our knowledge was applied to aid the introduction of the laryngoscope in the presence of large breasts.

The investigators hypothesized that using a special pillow to achieve a modified ramped position (by slight extension of the neck) at the beginning of the laryngoscopy would bring the breasts away from the laryngoscope. After successful introduction of the laryngoscope in the oral cavity, the head will be elevated using a head rest to achieve sniffing position.

The aim of this work is to investigate the feasibility of using the aforementioned modified ramped position for intubation of obese females in comparison to the traditional ramped position. ;
