Re-Adjustment of Sweep Gas Flow to the During the Rewarming Period of the Cardiopulmonary Bypass

Acıbadem Atunizade Hospital

Status: Enrolling

Conditions: Optimal Sweep Gas Flow; Determination of Optimal Sweep Gas Flow for Different Phases of Cardiopulmonary Bypass

Treatments: Other: Gas Flow Adjustment

Study type: Observational

Funder types: Other

Identifiers

NCT06013189

ATADEK 2019-19/21

Details and patient eligibility

About

The investigators designed this prospective observational study with the theory that alkalosis caused by decreased CO2 solubility due to temperature increase during the rewarming period of the Cardiopulmonary Bypass could be prevented by reducing the sweep gas flow during the rewarming period.

Enrollment: 90 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients over 18 years of age
• Elective CPB surgery

Exclusion criteria

• Patients undergoing minimally invasive surgery
• Patients undergoing robotic cardiac surgery,
• Patients undergoing deep hypothermia,
• Patients undergoing total circulatory arrest,
• Patients whose FiO2 requirement is high that cannot be applied to target gas flow

Trial design

Treatment:

Other: Gas Flow Adjustment

Group 3

Description:
