Paracetamol treatment for patent ductus arteriosus: practice and attitudes in Australia and New Zealand

Abstract

Aim: To describe the current clinical practices and attitudes of neonatologists towards paracetamol treatment of PDA in Australia (AU) and New Zealand (NZ).Method: A web-based survey of all neonatologists registered under the 2017 Australia New Zealand Neonatal Network (ANZNN) was conducted.Results: The response rate for the survey was 67%, (141/210). Of those respondents, 37% stated their unit had a written policy outlining how to treat patent ductus arteriosus (PDA). Of the written policies, 53% mentioned paracetamol treatment. The majority of the respondents (70%) have prescribed paracetamol for PDA closure. When comparing between countries, 79% of AU respondents had compared with 44% of NZ respondents. Successful ductal closure in the infants who received paracetamol was anecdotally reported by 61% of respondents. The main reasons for clinicians not prescribing paracetamol were due to preferential NSAID use (61%) and lack of evidence to indicate efficacy (49%).Conclusion: Many neonatologists in AU and NZ have prescribed paracetamol for PDA closure. However, considerable practice variations exist. The results from this study suggest there may be a role for paracetamol in the treatment of PDA, however, further research is required to clarify the optimal use and provide evidence of efficacy.
