Preoperative Cardiac Power Output and P-POSSUM Score

NCT07454564 | Recruiting

• 1 other identifier: 2025/5880
• Study Type: observational
• Target: 120
• Locations: 1 country
• Sites: 1

Brief Summary

This study aims to investigate the relationship between preoperative Cardiac Power Output (CPO), which reflects the pumping capacity of the heart, and the P-POSSUM score, a widely used surgical risk assessment tool, in patients aged 65 years and older undergoing abdominal surgery. Simple and non-invasive measurements performed in the preoperative period will be used to obtain CPO values and to evaluate whether these measurements are helpful in predicting postoperative morbidity and mortality. No additional procedures beyond routine clinical care will be performed as part of this observational study. The findings of this study may contribute to a more accurate assessment of surgical risk and help improve patient safety in the perioperative period.

Study Arms (1)

patients aged 65 years and older undergoing abdominal surgery

This cohort consists of patients aged 65 years and older undergoing abdominal surgery, including both elective and emergency procedures. All participants will undergo preoperative evaluation, including non-invasive measurement of Cardiac Power Output (CPO) and calculation of the P-POSSUM score, as part of routine clinical assessment. No experimental intervention will be performed in this study, and all patients will receive standard clinical care and follow-up. Postoperative clinical outcomes will be recorded prospectively.

Eligibility Criteria

• Age: 65 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Older Adult (65+)
• Sampling Method: Non-Probability Sample
