Abstract
BACKGROUND
Mid-Regional-Pro-Adrenomedullin (MR-Pro-ADM) is a marker of severity in a wide spectrum of pathological conditions such as sepsis, and cardiovascular dysfunction. Its usefulness as a predictor of morbidity and mortality in surgical patients has yet to be elucidated. We examined the ability of preoperative MR-Pro-ADM in predicting Postoperative Requirement of Organ Support (PROS).
METHODS
One centre, pilot, prospective observational cohort study, enrolling adult patients scheduled for major abdominal surgery. The accuracy of the MR-Pro-ADM to predict PROS was determined by area under the receiver operating characteristic curve (AUROC) analysis. An univariate analysis was performed to identify the association of PROS and the MR-Pro-ADM value with the best combination of sensitivity and specificity. A multivariate analysis was performed to identify preoperative MR-Pro-ADM as independent risk factor for PROS.
RESULTS
A total of 59 patients scheduled for major abdominal surgery were enrolled. The incidence of PROS was 13.6%. The association of MR-Pro-ADM levels with the incidence of PROS, was determined by an area under the ROC curve of 0.85 (95% CI: 0.74-0.96, p=0.002). The preoperative value of MR-Pro-ADM with the best combination of sensitivity and specificity to predict PROS was 0.87 nmol/l. Patients with preoperative serum levels of MR-Pro-ADM≥0.87 nmol/l had a significantly higher incidence of PROS (33.3% vs 4.9%, p=0.007). MR-Pro-ADM≥0.87 nmol/l was shown to be an independent risk factor for PROS (p=0.001; OR 9.758; IC 1.73-54.78) in the multivariate analysis.
CONCLUSION
The preoperative serum level of MR-Pro-ADM may be a useful biomarker of perioperative risk and to predict postoperative requirement of organic support (PROS) in adult patients scheduled for major abdominal surgery.
