Key result
Tonocap-derived gastric mucosal pH and luminal pCO2 predict postoperative complications.
Why the study?
Does automated air tonometry (Tonocap) predict postoperative complications in patients undergoing cardiac surgery?
Cohort (n=100)

p-value: p=0.022
Automated air tonometry using the Tonocap system provides variables that are predictive of postoperative complications in cardiac surgery patients.
No takes yet. Share an insight, caveat, or question.
May support postoperative risk stratification in cardiac surgery; leaves open whether Tonocap-guided interventions improve outcomes.
Bennett‐Guerrero et al. (2000) conducted a cohort in Coronary artery bypass graft or cardiac valve surgery (n=100). Tonocap-derived variables (gastric luminal partial pressure of carbon dioxide and pHi) was evaluated on Postoperative complication (in-hospital death or prolonged postoperative hospitalization > 14 days) (p=0.022). Tonocap-derived variables, including postoperative gastric mucosal pH (P=0.001) and gastric luminal partial pressure of carbon dioxide (P=0.022), predicted postoperative complications.
