Prospective case series study on the use of a novel analgosedation protocol for ultrasound-guided catheterization in Neonatal Intensive Care Unit.

Critically ill newborns admitted to Neonatal Intensive Care Unit often require a centrally inserted central catheters (CICCs) inserted by ultrasound-guided puncture of the internal jugular or brachio-cephalic vein. Achieving an appropriate level of sedation and analgesia is paramount for procedure success and patient safety, avoiding the potential risks associated with excessive deep sedation. The aim of this study is to evaluate the feasibility of a novel protocol of sedation. Data from 46 patients were prospectively collected. The feasibility was assessed throughout the monitoring of adverse events and the incidence of spontaneous movements. The procedure was completed in 100% of cases. There were no cases of escalation of the baseline ventilatory support despite the procedure and no case of hypotension, and all spontaneous movements were controlled with additional boluses when required. CONCLUSION:Our study represents the very first step towards the design of a validated protocol for analgosedation during ultrasound-guided CICC insertion in NICU. WHAT IS KNOWN:• Critically ill newborns admitted to Neonatal Intensive Care Unit often require a centrally inserted central catheter. • Achieving an appropriate level of sedation and analgesia is paramount for procedure success and patient safety, avoiding the potential risks associated with excessive deep sedation. WHAT IS NEW:• The use of this new protocol for analgosedation is able to achieve a good level of sedation and pain control without significant adverse event. • Ultrasound-guided CICC insertion can be performed even in non-ventilated newborns.
