Intervention type: DIAGNOSTIC_TEST
Group type: EXPERIMENTAL
Intervention: Aspiration of gastric air via nasogastric tube
Description: A nasogastric tube will be inserted at the beginning of laparoscopy and the air from the stomach will be aspirated with a syringe. The amount of air will be measured in ml.

Intervention: Arterial blood gas
Description: Arterial blood gases will we drawn at different time points to investigate oxygenation during the procedure. Blood gases will be taken before pre-oxygenation, before anesthesia induction, before laryngoscopy, immediately after intubation when the cuff of the tracheal tube is inflated.
