Superficial Cervical Plexus Block for Awake Large-Bore Central Line Placement in Parturients: A Case Series

Pregnant patients with high-risk conditions including abnormal placentation or severe cardiovascular disease may require large-bore central venous access at the time of delivery. Central lines are generally inserted while obstetric patients are awake, either because neuraxial anesthesia is planned or to minimize fetal exposure to anesthetic medications. Despite local infiltration, the procedure can cause significant patient discomfort. This case series describes use of a superficial cervical plexus block (SCPB) to facilitate line placement in 4 pregnant women with high-risk conditions. SCPB is technically straightforward with low reported complication rates and should be considered for pregnant patients requiring large-bore central lines.
