Details and patient eligibility

About

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.

Full 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.

Enrollment: 60 patients

Sex: All

Ages: 20 to 50 years old

Volunteers: No Healthy Volunteers

• Inclusion Criteria:

  1. Patients between the ages of 20 and 50 years

  3. Patients with body mass index of 40 and over

Exclusion criteria

1. cardiopulmonary disease
2. patients with previous abdominal or thoracic surgery or cerebrovascular disease

60 participants in 2 patient groups

CPAP

Other group

Description:

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.

Treatment:

Other: CPAP preoxygenation

standard preoxygenation

No Intervention group

Description:

During the preoxygenation, the ventilator device will be put in spontaneous mode and the procedure will continue until the End-tidal O2 concentration ≥90% is removed without additional pressure.
