The Effect of Preoxygenation on Gastric Decompression in Laparoscopic Cholecystectomies

Exclusion criteria

for participation in the study:

• Age under 18 or over 65 years,
• Patients who do not wish to participate in the study,
• Patients classified as ASA IV or V,
• History of difficult intubation.

Criteria for termination of study participation:

• Failure to perform endotracheal intubation on the first attempt
• Presence of difficult intubation
• Occurrence of oropharyngeal or laryngeal trauma during intubation

Expected Benefits and Risks of the Study:

We hypothesize that in the operating rooms of the Oncology Hospital at Ankara City Hospital, Ministry of Health of the Republic of Türkiye, preoxygenation instead of mask ventilation during general anesthesia for laparoscopic cholecystectomies may reduce gastric insufflation, potentially improve surgical comfort, and have a positive effect on postoperative sore throat caused by swallowing, since the use of orogastric tubes may no longer be necessary.
