Driving Pressure During General Anesthesia for Open Abdominal Surgery

Not Applicable
Active, not recruiting
Conditions
Postoperative Respiratory Complication
Interventions
Procedure: Individualized high PEEP strategy
Registration Number
NCT03884543
Lead Sponsor
Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA)
Brief Summary

The purpose of this international multicenter, patient and outcome-assessor blinded randomized controlled trial is to determine whether the application of an individualized high PEEP strategy, aiming at avoiding an increase in the driving pressure during intraoperative ventilation, protects against the development of postoperative pulmonary complications.

Arm && Interventions
GroupInterventionDescription
Individualized high PEEP strategyIndividualized high PEEP strategyRecruitment maneuver (performed after induction of anesthesia, after any disconnection from the mechanical ventilator, and before extubation) followed by the decremental PEEP trial to determine the highest level of PEEP resulting in the lowest driving pressure. This is again followed by a recruitment maneuver, after which PEEP is set at the level indicated by the decremental PEEP trial.
Primary Outcome Measures
NameTimeMethod
Proportion of participants developing one or more postoperative pulmonary complications (PPCs)The first 5 postoperative days

Severe respiratory failure; ARDS; Suspected pulmonary infection; Pulmonary infiltrate ; Pleural effusion; Atelectasis; Pneumothorax; Bronchospasm; Aspiration pneumonitis; Cardiopulmonary edema

Secondary Outcome Measures
NameTimeMethod
Rate of mild respiratory failuresThe first 5 postoperative days

Defined as a PaO2 \< 60 mmHg (or \< 7.9 kPa) or SpO2 \< 90% in room air, but responding to supplemental oxygen (excluding hypoventilation)

Number of participants with an unscheduled Intensive Care Unit (ICU) (re-) admission and length of stay in Intensive care unitFrom the day of surgery until the day of discharged, up to day 90
Assessment of postoperative wound healingThe first 5 postoperative days

Visual inspection of the following: impairment of wound healing and/or wound infection;

Rate of intra-operative complicationsFor the length of the anesthesia, which will be estimated 2 to 5 hours.
The total amount and type of intraoperative fluid administrationFor the length of the anesthesia, which will be estimated 2 to 5 hours

Type of fluids: colloids, crystalloids or blood products

Proportion of participants developing one or more post-operative extra-pulmonary complicationsThe first 5 postoperative days

Including sepsis (according to the SEPSIS-3 definition), septic shock (defined as sepsis with persisting hypotension requiring vasopressors to maintain MAP ≥ 65mmHg and having a serum lactate level \>2 mmol/L despite adequate volume resuscitation), extra-pulmonary infection (including wound infection and any other infection), anastomic leak and acute renal failure (as defined by AKIN \[Mehta RL., et al., Acute Kidney Injury Network: report of an initiative to improve outcomes in acute kidney injury. Crit Care, 2007\])

Rate of all-cause mortality and in-hospital mortalityPostoperative day 5, day 30 and day 90
Length of hospital stayFrom the day of surgery until the day of discharge, up to day 90
