Emergency Dynamic Central Venous Cannulation in Preterm Neonates- A Case Series

Abstract

Neonatal venous cannulation is one of the challenges faced by Anaesthesiologists in routine practice. Neonatal cannulation is extremely difficult and time consuming and it has become an inevitable procedure in neonatal intensive care unit, because of the small vessel diameter and sometimes it is impossible to differentiate between artery and vein. Routinely umbilical vein, scalp vein and peripherally inserted central catheters cannulation are done during initial neonatal period. Central vein cannulation is needed in sick neonates for nutrition, antibiotics, venous sampling, and inotropic support and enables haemodynamics monitoring. Even with the point of care ultrasound, neonatal cannulation is technically challenging in well-experienced hands. Cannulation in a preterm neonate is highly demanding and nightmarish for all intensivists. The present case series aimed to show the successful placement of ultrasound guided supraclavicular subclavian cannulation in a very low birth preterm (less than 1500 gm) in three septic neonates. All three cannulations were done bedside in Neonatal Intensive Care Unit (NICU) with close monitoring of heart rate, pulse oximeter and electrocardiogram. Venipuncture was done under ultrasound guidance. After identifying the anatomic landmarks, subclavian cannulation was done using Seldinger technique. Subclavian cannulation was preferred because of easy accessibility, comfortable fixation and low infection rate
