The Comparison of the Methods Applied in Bariatric Surgery in Terms of Preoxygenation Time

Not Applicable

Completed

• Conditions: Time to Reach 90% Endtidal Oxygen During Preoxygenation
• Interventions: Other: CPAP preoxygenation

• Registration Number: NCT03807375
• Lead Sponsor: Ankara Diskapi Training and Research Hospital

Brief Summary

The aim of the study was to evaluate the preoxygenation time by observing patients undergoing preoxygenation with CPAP (Continuous Positive Airway Pressure) and Mask Ventilation in the clinic.

Detailed Description

Criteria for inclusion in the study:

Planned elective bariatric surgery under general anesthesia ASA 1-2 class Between 20-50 years 50 patients

1. Group: Patients undergoing CPAP (Continuous Positive Airway Pressure) during preoxygenation will be included.

2. Group: Patients undergoing preoxygenation without CPAP will be included

In both groups, the time from the anesthesia device to the endtidal O2 90% and the endtidal CO2 value in this order will be recorded.

Heart rate, blood pressure, endtidal O2 and CO2 values will be recorded during preoxygenation and after intubation.

Arm && Interventions

Group	Intervention	Description
CPAP	CPAP preoxygenation	During preoxygenation, the ventilator device will be placed in spontaneous mode and set as CPAP: 5 cmH2O. The process will continue until the end-tidal O2 concentration ≥ 90% is removed.

Primary Outcome Measures

Name	Time	Method
prevention of side effects of hypoxia	10 minutes	hypoxia-induced arrhythmia hypotension tachycardia
Prevention of desaturation during intubation	5 minutes	Prevent desaturation of the apnea period during endotracheal intubation in bariatric surgery
