Can perioperative pCO2 gaps predict complications in patients undergoing major elective abdominal surgery randomized to goal-directed therapy or standard care? A secondary analysis

J Clin Monit ComputPublished Secondary analysis of a multicentre randomised controlled trial

Authors' conclusion

In our study, pCO2 gap was a poor predictor of major postoperative complications at all selected time points.

Study context

Population
Patients undergoing high-risk elective abdominal surgery randomised to goal-directed therapy (GDT) or standard care
Participants
464 patients
Comparison
Complications vs No complications
Primary endpoint
Prediction of postoperative complications by perioperative pCO2 gaps (venous–arterial CO2 pressure difference) at 4 time points
Follow-up
30 days

Primary result

As reported in the abstract

pCO2 gap at end of surgery · end of surgery

P = 0.005

AUC for predicting complications from pCO2 gaps at all time points
between 0.5 and 0.6

Further findings

Correlation between ScvO2 and pCO2 gaps · all time points

Weak correlation, ρ between - 0.40 and - 0.29, p < 0.001

pCO2 gap, GDT vs standard care · all selected time points

No difference between GDT and standard care at any time point
