Investigational drug(s) / intervention(s)

High flow nasal cannula oxygen is appliedHigh flow nasal cannula oxygen is not applied

High flow nasal cannula oxygen is applied: Atelectasis evaluation with lung ultrasound is performe and score in 6 different areas before and after High flow nasal cannula oxygen. Pulmonary function tests and blood gas parameters are compared.During the procedure, the patient's blood pressure, heart rate, oxygen saturation, any complications that may develop will be recorded.Induction of anesthesia; difficult airway management, difficult mask and / or difficult intubation incidence, Mallampati scores, the use of one of the difficult intubation techniques during intubation, perioperative mechanical ventilation parameters (ventilation mode, tidal volume, respiratory frequency, end of tidal CO2 (carbon dioxide) pressure, PEEP usage, SpO2 (saturation oxygen), airway peak pressure, urine volume, arterial blood gas parameters are recorded.

High flow nasal cannula oxygen is not applied: Apply preoxygenation with facemask. Prior to induction of general anesthesia, preoxygenation will be applied with an oxygen supplement of 5 l / min to an endtidal O2\> 90%.Atelectasis evaluation with lung ultrasound is performe and score in 6 different areas before and after preoxygenation.

Study summary

Evaluate the effects of high-flow nasal oxygen therapy on atelectasis in the perioperative period by lung ultrasound (LUS) in bariatric surgery patients.

Primary outcome measure(s)

Evaluation of postoperative atelectasis in bariatric surgery patients — Up to 20 minutes in postoperative care unit
Postoperative atelectasis develops in patients undergoing laparoscopic bariatric surgery under anesthesia.After the operation a researcher will perform lung ultrasonography postoperative at minute 5. reseracher will detect 6 region of each lung totally 12 regions. the researcher will record the modified and original lung ultrasonography scores (LUS score) of the patients. LUS Score is a scoring system to eveluate atelectasis of lung and scores 1-3 points for each region (min score 0 max score 36)
