About

This study will include pregnants who preferred to undergo general anesthesia for elective cesarean section. Ramped and sniffing positions of pregnant women during ventilation and intubation will be compared. The aim of this study is to investigate which position provides easier and faster intubation in pregnant women for cesarean section.

Full description

Estimates of the frequency of difficult and failed intubation in the obstetric population vary within a wide range of percentiles. Several times higher than those reported for the general surgery population. Functional Residual Capacity decreases by 10% - 25% in Pregnant women. Pregnant women are more susceptible to hypoxia as a result of this decline, which also encourages intubation to occur more rapidly. Intubation success and shortening of intubation time have improved positively with videolaryngoscopes. On the other hand, the position of the patient during intubation contributes to the speed and success of intubation. It has been shown that intubation is faster and first-pass success is higher in the ramped position in morbidly obese patients.This study will compare the effectiveness of ramp and sniffing positions on intubation time and success in obese patients and pregnant women with similar physical changes.
