Hypothesis
This study aimed to assess the safety and efficacy of Del Nido cardioplegia compared to hyperkalemic blood cardioplegia for patients with prolonged aortic cross-clamp times.
Conclusion
Del Nido cardioplegia provided similar post-operative troponin profiles and clinical outcomes compared to hyperkalemic blood cardioplegia for surgeries with aortic cross-clamp times over 90 minutes.
Supporting Evidence
- Patients receiving Del Nido had a higher rate of spontaneous return of rhythm.
- There was no significant difference in post-operative complications between the two groups.
- Del Nido cardioplegia required less volume and fewer doses compared to hyperkalemic blood cardioplegia.
Takeaway
Doctors compared two methods of protecting the heart during surgery to see which one works better when the heart is stopped for a long time. They found both methods are equally safe.
Methodology
A single-centre, retrospective cohort study comparing patients receiving Del Nido cardioplegia to those receiving hyperkalemic blood cardioplegia, with data collected from a cardiac surgery registry.
Potential Biases
Potential biases due to the retrospective nature of the study and variations in surgeon practices.
Limitations
The study is retrospective and may have biases related to patient selection and the inability to control for all confounding variables.
Participant Demographics
Patients undergoing cardiac surgery with aortic cross-clamp times longer than 90 minutes, with a median age of 64 years.
