Our Summary
This study addresses the problem of bleeding, which is a frequent issue for children undergoing heart surgery. One approach to reduce bleeding involves using drugs known as antifibrinolytics. The study aimed to assess how effective and safe these drugs are, and how different doses affect the outcome.
The researchers looked at randomised trials from 1980 to 2019, focusing on patients under 18 years old without pre-existing blood disorders. They examined the amount of bleeding after surgery, the need for blood transfusion, death rates, and safety measures such as blood clots, allergic reactions, kidney or brain problems, and seizures.
Of the 209 articles reviewed, 30 were included in the study. Three drugs were evaluated: aprotinin, tranexamic acid (TXA), and epsilon-aminocaproic acid (EACA). The studies involved a range of ages and weights, and the quality of the studies varied.
The findings showed that all three drugs reduced blood loss after surgery compared to a control group. They also lowered the need for blood product transfusion in the 24 hours following surgery. However, there was no clear link between the dose of TXA or aprotinin and their effectiveness, and the studies did not have enough data to show significant differences in death rates, blood clots, allergic reactions, and kidney or brain problems.
In conclusion, all three drugs seemed to be effective, so the drug with the least side effects should be used. However, more comprehensive studies are needed to compare the safety and appropriate dosages of these drugs in children.
FAQs
- What was the main purpose of this study regarding pediatric cardiac surgery?
- What were the key findings of the study on the use of antifibrinolytics in pediatric heart surgery?

Doctor’s Tip
A helpful tip a doctor might give a patient about pediatric cardiac surgery is to discuss with the medical team the use of antifibrinolytic drugs, such as tranexamic acid (TXA), aprotinin, or epsilon-aminocaproic acid (EACA), to help reduce bleeding during and after surgery. These drugs have been shown to be effective in reducing blood loss and the need for blood transfusions in pediatric patients undergoing heart surgery. It is important to weigh the benefits of these drugs against any potential risks and to follow the medical team’s recommendations for dosage and administration.
Suitable For
Pediatric cardiac surgery is typically recommended for patients with congenital heart defects, acquired heart disease, or other heart conditions that require surgical intervention. These patients may include infants, children, and adolescents who have conditions such as:
- Tetralogy of Fallot
- Transposition of the great arteries
- Atrial septal defect
- Ventricular septal defect
- Coarctation of the aorta
- Hypoplastic left heart syndrome
- Pulmonary valve stenosis
- Aortic valve stenosis
- Ebstein’s anomaly
- Double outlet right ventricle
These patients may experience symptoms such as cyanosis, shortness of breath, fatigue, poor growth, and arrhythmias, among others. Pediatric cardiac surgery is recommended when these conditions are severe and cannot be managed effectively with medications or other non-invasive treatments.
Timeline
Before pediatric cardiac surgery, a patient typically undergoes a series of diagnostic tests, consultations with the surgical team, and pre-operative preparations. This may include blood tests, imaging scans, and discussions about the surgery and post-operative care. The patient may also need to follow certain dietary restrictions or medication adjustments.
During the surgery, the patient is under general anesthesia and the cardiac surgeon performs the necessary procedures to correct the heart defect. The length and complexity of the surgery will vary depending on the specific condition being treated.
After the surgery, the patient is closely monitored in the intensive care unit (ICU) for a period of time to ensure stable recovery. This includes monitoring vital signs, pain management, and potential complications. The patient may also require mechanical ventilation and other supportive therapies.
In the following days and weeks, the patient will transition to a regular hospital room and continue to recover under the care of the medical team. This may involve physical therapy, medication management, and follow-up appointments to monitor progress and address any concerns.
Overall, the timeline before and after pediatric cardiac surgery involves thorough preparation, a complex surgical procedure, and a period of intensive care and recovery to ensure the best possible outcome for the patient.
What to Ask Your Doctor
Some questions a patient should ask their doctor about pediatric cardiac surgery and the use of antifibrinolytics include:
- What are the potential benefits of using antifibrinolytics during my child’s heart surgery?
- What are the potential risks or side effects associated with these drugs?
- How will the decision to use antifibrinolytics be made for my child’s specific case?
- Are there any alternative treatments or approaches that could be considered instead of antifibrinolytics?
- How will the effectiveness of the antifibrinolytics be monitored during and after the surgery?
- What is the recommended dosage of the antifibrinolytic drug for my child’s age and weight?
- What steps will be taken to prevent any potential complications associated with the use of antifibrinolytics?
- What is the overall success rate of using antifibrinolytics in pediatric cardiac surgery based on current research?
- How will the decision to use antifibrinolytics be communicated with the rest of the medical team involved in my child’s care?
- Are there any long-term implications or considerations to be aware of regarding the use of antifibrinolytics in pediatric cardiac surgery?
