Filter by:Since the first successful percutaneous closure under transoesophageal echocardiographic (TEE) guidance, many centres explored transcatheter procedures without fluoroscopy. This single centre study aims to show the feasibility and safety of percutaneous patent ductus arteriosus (PDA) closure under echocardiography-only guidance during our one-year experience. Patients with PDA were recruited for percutaneous PDA closure guided by either fluoroscopy or echocardiography-only in National Cardiovascular Center Harapan Kita. Patients were evaluated clinically and radiologically using TTE at 6, 24 and 48 hours after the procedure. Primary endpoint was the procedural success. Secondary endpoints were the procedural time and the rate of adverse events. Echocardiography-guided PDA closure is non-inferior to fluoroscopy-guided PDA closure, with similar procedural times. However, this method is operator-dependent and requires an experienced team for it to be performed successfully.
To evaluate whether utilizing a standardized patent ductus arteriosus (PDA) treatment algorithm in managing ELBW (extremely low birth weight) neonates ≤1000 grams (g) improves clinical outcomes and helps prevent undesirable side effects from PDAs.
Aim of study: To conduct an observational study to collect cerebral and renal perfusion data through NIRS before and after treatment of PDA by medication or by PDA ligation. The data post treatment would form the basis for normative baseline data in VLBW preterm newborn babies, particularly in the Asian population. Study population/inclusion criteria: VLBW newborn babies with hemodynamically significant PDA by echocardiography. Exclusion criteria: Major malformations Moribund patients
There is a report that acetaminophen may have a role in pharmacological closure of PDA (Patent arterial duct) in preterm infants. The investigators conducted this open label non randomized and non control study to try to support that report.
Background: Patent ductus arteriosus (PDA) continues to be one of the most common problems in premature infants. Pharmacological closure of PDA with intravenous (IV) indomethacin was first reported in 1976, however, concern remains regarding the safety of indomethacin, which affects renal, GI and cerebral perfusion and may lead to complications such as transient or permanent renal dysfunction, NEC, GI hemorrhage, and reduced cerebral oxygenation. Recently, IV ibuprofen has been shown to be effective for the closure of patent ductus arteriosus in premature infants, without reducing mesenteric, renal, or cerebral blood flow. We have developed the echocardiographic PDA flow pattern as a guide for PDA treatment, fewer doses of drugs were needed to achieve acceptable closing rates. We have also reported that IV ibuprofen is as effective as IV indometacin for the PDA treatment in extremely premature infants, without increasing the incidence of complications in a randomised controlled trial. Several studies reported that oral ibuprofen may be effective for PDA treatment. To date there is no firm conclusion as to the efficacy and safety of oral ibuprofen compared with IV ibuprofen for PDA closure in extremely premature infants. Objective: Since the efficacy of pharmacological closure of PDA is related to gestational age, and extremely premature infants carry the highest rate of mortality and morbidity. We intend to conduct a randomized controlled trial to compare oral and intravenous ibuprofen for treatment of PDA in this high-risk population of extremely premature infants. Methods: Extremely premature infants (gestational age < 28 weeks) admit to the NICU will be eligible for enrollment. Informed parental consent will be obtained according to the Institutional Review Board's instructions. Extremely premature infants with respiratory distress syndrome (RDS) and PDA confirmed by echocardiography will be randomly assigned to receive either oral or IV ibuprofen. The subsequent doses of ibuprofen are also determined according to our specific echocardiographic PDA flow patterns at intervals of once every 24 hours from the last dose. The dosage of oral or ibuprofen is 10 mg/kg (1 ml) and then 5 mg/kg at 24-hour intervals as indicated by echocardiographic PDA flow pattern. Sample Size Calculation and Length of the Study Period: About 50-60 extremely premature infants will be admitted to our NICU each year. To prove with McNemar's Test at a one-sided significance level of 5% and a power of 90% that using oral ibuprofen instead of IV ibuprofen results in comparable PDA closure rates, only 31 extremely premature infants with RDS and PDA have to be enrolled. Allowing for attrition and exclusion from the final study groups, the length of the study period will be safe to set to 2 years. Expected Results: We expect to determine whether oral ibuprofen is effective and safe in inducing PDA closure in extremely premature infants and to compare the complications between infants treated with oral ibuprofen and those with IV ibuprofen.
