Echocardiography performed by the neonatologist: the impact on the clinical management

BackgroundThe aim of this study was to assess whether neonatologist-performed echocardiography (NPE) changed the previously planned hemodynamic approach in critically ill newborn infants.MethodsThis prospective cross-sectional study included the first NPE of 199 neonates. Before the exam, the clinical team was asked about the planned hemodynamic approach and the answer was classified as an intention to change or not to change the therapy. After being informed about the NPE results, the clinical management was grouped as performed as previously planned (maintained) or modified.ResultsNPE modified the planned pre-exam approach in 80 cases (40.2%; 95% CI: 33.3-47.4%), and variables associated with an increased chance of this modification were exams to assess pulmonary hemodynamics (prevalent ratio (PR): 1.75; 95% CI: 1.02-3.00) and to assess systemic flow (PR: 1.68; 95% CI: 1.06-2.68) in relation to those requested for patent ductus arteriosus, pre-exam intention of changing the prescribed management (PR: 2.16; 95% CI: 1.50-3.11), use of catecholamines (PR: 1.68; 95% CI: 1.24-2.28) and birthweight (per kg) (PR: 0.81; 95% CI: 0.68-0.98).ConclusionThe NPE was an important tool to direct hemodynamic management in a different approach from the previous intention of the clinical team, mainly for critically ill neonates.ImpactThis study shows that neonatologist-performed echocardiography guides the therapeutic planning in the NICU, mainly in the more unstable newborns, with lower birthweight and receiving catecholamines.Exams requested with the intention of modifying the current approach were more likely to change the management in a different way than planned pre-exam.
