Hypothesis
Is Del Nido cardioplegia more effective than Bretschneider histidine-tryptophan-ketoglutarate cardioplegia in protecting the heart during prolonged ischaemia?
Conclusion
Del Nido cardioplegia was found to be superior to Bretschneider cardioplegia in terms of heart function and recovery after prolonged ischaemia in pigs.
Supporting Evidence
- Del Nido cardioplegia showed better left ventricular performance compared to Bretschneider cardioplegia.
- Haemoglobin levels decreased less in the Del Nido group than in the Bretschneider group.
- More animals in the Bretschneider group required defibrillation to restore normal heart rhythm.
- Del Nido cardioplegia resulted in lower endothelial dysfunction markers compared to Bretschneider.
Takeaway
This study tested two solutions used to protect the heart during surgery in pigs. One solution worked better at keeping the heart healthy after being stopped for a long time.
Methodology
Landrace pigs were randomized to receive either Del Nido or Bretschneider cardioplegia, followed by measurements of heart function and blood parameters after cardiac arrest and reperfusion.
Potential Biases
The surgical team could not be blinded to the cardioplegic solution used, which may introduce bias.
Limitations
The study was conducted on healthy pigs, which may not fully represent the conditions in human patients with heart disease.
Participant Demographics
Landrace pigs weighing 50–60 kg.
