Hemodynamic instability is very common in sick neonates and the currently used traditional hemodynamic monitoring tools lack sensitivity and specificity. Hemodynamic evaluation on echocardiography can provide direct information regarding the pathophysiology causing the hemodynamic instability and help the bedside clinician in making a personalized treatment approach based upon the deranged pathophysiology. Assessment of cardiac function and hemodynamics is essential in the management of neonates with cardiorespiratory failure, and hence neonatologist-performed echocardiography is becoming an essential tool in modern neonatal care.

Article Synopsis
  • Emergent laparotomy is linked to high rates of wound complications like surgical site infections (SSIs) and fascial dehiscence, and the study evaluates the efficacy of triclosan-coated barbed (TCB) sutures compared to polydioxanone (PDS) sutures in reducing these issues.
  • In the one-year study, 206 patients were divided into TCB and PDS groups, revealing that TCB closure led to significantly lower rates of fascial dehiscence (4% vs. 14%) and a trend toward decreased SSIs (11% vs. 21%).
  • The results indicate that using TCB for fascial closure during emergency laparotomy effectively reduces complications, particularly
