Prediction of Difficult Mask Ventilation in Obese Population Undergoing Emergency Surgery

Sponsor: Minia University

Summary

The current study is an observational, prospective study. It will be conducted in the emergency operative theatre, Alfayoum University, Alfayoum, Egypt. Identification of difficult mask ventilation among obese population is crucial specially in emergency settings with high risk of aspiration pneumonia or hypoxemia. No clinical predicrors were identified up till now. While the patient lies supine with the head in neutral position, Ultrasound guided (high frequency- depth adjusted at 3-4 cm) will be placed in the in submental region to measure the distance between skin to hyoid bone . Hyoid bone will be identified as a hyperechoic shadow below the mentum. Three measures will be taken and the average will be calculated. All candidates will sign informed consent pre-scanning and retain their right to withdraw at any time without compromising their medical care. Exclusion criteria will include elective operations, patient refual, previous neck surgery, prescence of surgical emphysema, emergency cesarean section and submental abcess.
