Exploration of the Appropriate Combination of Positive End Expiratory Pressure and Tidal Volume Using the Intratidal Compliance Volume Profile in Children

May 3, 2022 updated by: Jin-Tae Kim, Seoul National University Hospital

Exploration of the Appropriate Combination of Positive End Expiratory Pressure and Tidal Volume Using the Intratidal Compliance-volume Profile in Children

In children under 6 years of age undergoing regular surgery during general anesthesia, the intratidal compliance profile is evaluated when different tidal volumes are applied at different positive end expiratory pressures.

Then determine the most appropriate combination of positive end-tidal pressure and tidal volume.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Evaluation of intratidal compliance

When the patient is in the supine position 10 minutes after induction of anesthesia, the following 4 mechanical ventilator settings are applied to the patients in order.

  1. Positive end-expiratory pressure 8 cmH2O, tidal volume 8 ml/kg
  2. Positive end-expiratory pressure 10 cmH2O, tidal volume 5 ml/kg
  3. Positive end-expiratory pressure 10 cmH2O, tidal volume 8 ml/kg
  4. Positive end-expiratory pressure 12 cmH2O, tidal volume 5 ml/kg
Other: Changes in positive end-expiratory pressure and tidal volume

When the patient is in the supine position 10 minutes after induction of anesthesia, the following 4 mechanical ventilator settings are applied to the patients in order.

Positive end-expiratory pressure 8 cmH2O, tidal volume 8 ml/kg Positive end-expiratory pressure 10 cmH2O, tidal volume 5 ml/kg Positive end-expiratory pressure 10 cmH2O, tidal volume 8 ml/kg Positive end-expiratory pressure 12 cmH2O, tidal volume 5 ml/kg

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intratidal compliance profiles in each ventilator settings
Time Frame: During general anesthesia (up to about 50 min-1 hr after induction of anesthesia)

The investigators will determine Intratidal compliance profile using the changes in compliance over time

--> I, merely increasing compliance profile; IH, increasing turning into horizontal compliance profile; D, merely decreasing compliance profile; HD, horizontal turning into decreasing compliance profile; IHD, increasing turning into horizontal and further turning into decreasing compliance profile If compliance profile is I, the PEEP is low. On the other hand, compliance profile is D, PEEP level is considered to be high.
During general anesthesia (up to about 50 min-1 hr after induction of anesthesia)
