The Myocardial Protective Effects of a Moderate-potassium Blood Cardioplegia in Pediatric Cardiac Surgery
A study testing MP (moderate potassium) group and HP (High potassium) group in people with Congenital Heart Disease, run by Xijing Hospital at 1 site in China.
Trial summary
The investigators previously investigated the cardioprotective effect of an adenosine-lidocaine cardioplegia with moderate-potassium (K+, 10.0 mmol/L) in pediatric cardiac surgery, which was associated with better myocardial protective effects when compared with conventional high-potassium cardioplegia.

About this study
Official title: The Myocardial Protective Effects of a Moderate-potassium Blood Cardioplegia in Pediatric Cardiac Surgery:a Randomized Controlled Trial
The investigators previously investigated the cardioprotective effect of an adenosine-lidocaine cardioplegia with moderate-potassium (K+, 10.0 mmol/L) in pediatric cardiac surgery, which was associated with better myocardial protective effects when compared with conventional high-potassium cardioplegia. However, this cardioplegia could not be sucked back into the cardiopulmonary bypass (CPB) circuit because of excessive hemodilution and severe systemic hypotension induced by adenosine. Therefore, the investigators supposed that a moderate-potassium (K+, 10.0 mmol/L) blood cardioplegia without adenosine could also arrest the heart and have better myocardial protective effects compared with conventional hyperkalamic cold blood cardioplegia during cardiac operations without excessive hemodilution and systemic hypotension.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MP (moderate potassium) groupDrug
Also called moderate potassium cardioplegia
Hearts were arrested with cold blood cardioplegia with moderate potassium concentration (K+, 10mmol/L)during cardiac operation
HP (High potassium) groupDrug
Also called High potassium cardioplegia
Hearts are arrested with cold blood cardioplegia with high potassium concentration (K+, 20mmol/L)during cardiac operation.
| Study group | Role | What they receive |
|---|---|---|
| MP group | Experimental | Hearts are arrested with cold blood cardioplegia with moderate potassium concentration (K+, 10mmol/L) during cardiac surgery. Receives: Drug: MP (moderate potassium) group |
| HP group | Active comparator | Hearts were arrested with cold blood cardioplegia with high potassium concentration (K+, 20mmol/L) during cardiac operation Receives: Drug: HP (High potassium) group |
What is being measured
The primary outcome is the main question the study is designed to answer.
post-operative Serum cTnI concentration decreased significantly in 24hours
myocardial injury could be sensitively reflected by post operative Serum cTnI concentration.
Measured: 24h after myocardial reperfusion
