NCT03569774

Brief Summary

The aim of the prospective crossover study is to investigate the effect of individualized positive end-expiratory pressure (PEEP) on measures of tissue oxygenation, compared with low PEEP.

Outcome Measures

Primary Outcomes (1)

  • Cerebral oximetry

    Cerebral oximetry (a measure of oxygen levels in the brain) as measured by near-infrared spectroscopy (noninvasive monitor applied to the forehead)

    Change from baseline cerebral oximetry at the end of each intraoperative 20 minute experimental period. All measurements are made during the 4-6 hour surgery.

Secondary Outcomes (5)

  • Arterial blood oxygen tension (PaO2)

    Measured at baseline, and then at the end of each 20 minute intraoperative experimental period. All measurements are made during the 4-6 hour surgery.

  • Venous blood oxygen tension (PvO2)

    Measured at baseline, and then at the end of each 20 minute intraoperative experimental period. All measurements are made during the 4-6 hour surgery.

  • Venous blood oxygen saturation (SvO2)

    Measured at baseline, and then at the end of each 20 minute intraoperative experimental period. All measurements are made during the 4-6 hour surgery.

  • Cardiac output

    Measured at baseline, and then at the end of each 20 minute intraoperative experimental period. All measurements are made during the 4-6 hour surgery.

  • Phenylephrine dose

    Total dose of phenylephrine administered during each intraoperative 20 minute experimental period. All measurements are made during the 4-6 hour surgery.

Study Arms (2)

Individualized PEEP

EXPERIMENTAL

Individualized PEEP will be identified by performing a decremental PEEP protocol which will determine the level of PEEP that correlates with maximal lung compliance in each subject. Subjects will receive one-lung ventilation with individualized PEEP

Procedure: One-lung ventilation with individualized PEEP

Low PEEP

ACTIVE COMPARATOR

Subjects will receive One-lung ventilation with low PEEP (5 cmH2O)

Procedure: One-lung ventilation with low PEEP

Interventions

During one-lung ventilation for lung resection surgery, PEEP will be applied. After a subject's individualized PEEP (PEEP that corresponds to maximum lung compliance) is determined, the subject will receive one-lung ventilation with individualized PEEP.

Individualized PEEP

Subjects will receive one-lung ventilation with low PEEP (5 cmH2O)

Low PEEP

Model Details: Mechanical ventilation with individualized PEEP will be compared to mechanical ventilating with low PEEP during lung isolation in each subject. Each subject will receive one PEEP level then will receive the second PEEP level. The order in which each subject receives the PEEP level will be randomized.
