Effect of prostaglandin on early surgical mortality in obstructive lesions of the systemic circulation
Insights
Preoperative prostaglandin infusion significantly reduced surgical mortality in infants with obstructive systemic circulation lesions. This vital treatment prevented deaths in a high-risk group, improving infant survival rates.
Area of Science:
- Pediatric Cardiology
- Neonatal Surgery
- Pharmacology
Background:
- Infants with obstructive systemic circulation lesions face high surgical mortality.
- Preoperative management strategies are crucial for improving outcomes in this vulnerable population.
Purpose of the Study:
- To evaluate the impact of preoperative prostaglandin infusion on surgical mortality in neonates with obstructive systemic circulation lesions.
- To identify risk factors associated with hospital death in this patient cohort.
Main Methods:
- Retrospective review of records for infants (≤28 days) operated for obstructive systemic circulation lesions between 1979 and 1981.
- Comparison of mortality rates between infants who received preoperative prostaglandin infusion and those who did not.
- Analysis of preoperative variables including cardiac output and blood urea concentration.
Main Results:
- Eleven of 38 (29.0%) infants not receiving prostaglandin died, versus none of 14 treated with prostaglandin.
- Preoperative low cardiac output was a potential risk factor for hospital death.
- Raised blood urea concentration was associated with mortality only in non-prostaglandin treated patients.
Conclusions:
- Short-term preoperative prostaglandin infusion is associated with a significant reduction in early surgical mortality.
- Prostaglandin administration appears to be a highly favorable intervention for high-risk infants undergoing surgery for obstructive systemic circulation lesions.
Abstract:
To examine the effect of preoperative prostaglandin infusion on surgical mortality the records of all patients aged less than or equal to 28 days operated between January 1979 and December 1981 for obstructive lesions of the systemic circulation were reviewed. Forty patients had coarctation of the aorta, five interrupted aortic arch, and seven critical aortic stenosis. Fourteen patients received intravenous prostaglandin before operation. Among preoperative variables low cardiac output was identified as a possible risk factor for hospital death, whereas the presence of a raised blood urea concentration was possibly significantly associated with hospital mortality only in patients not treated with prostaglandin. The preoperative administration of prostaglandin had a strongly favourable influence: 11 out of 38 (29.0%) patients who did not receive prostaglandin died compared with none of 14 treated with prostaglandin. The two groups were otherwise comparable with respect to the incidence of coagulopathy, urgency of operation, associated anomalies, and other medical treatment. Mean age at operation was younger and mean admission blood urea concentration higher in the group treated with prostaglandin, whereas the incidence of preoperative low cardiac output was probably higher. It is concluded that short term preoperative infusion of prostaglandin in associated with a significant reduction in early surgical mortality in this high risk group of infants.
