Neonatal limb ischemia: caudal blockade and NIRS monitoring.

ABSTRACT

The treatment of neonatal limb ischemia (LI) is challenging for neonatologists. Peripheral nerve blockade (PNB), alone or in association with other therapies, represents a valid therapy in case of vascular spasm or thromboembolic events responsible for LI. In the present case report, we describe the clinical history of a preterm neonate with catheter-related thrombosis of the left leg. PNB was not performed according to the traditional technique but rather by a peridural catheter left in situ for 9 days with a continuous infusion of ropivacaine. In conclusion, the effectiveness of this approach was confirmed by the contemporary near-infrared spectroscopy monitoring, documenting gradual improvement of leg perfusion.
