Increased risk of complications in lower versus upper limb peripheral intravenous cannulation in children with severe neurological impairment.

Abstract

Obtaining peripheral intravenous catheter (PIVC) access in children with severe neurological impairment (SNI) is often challenging and commonly associated with complications, including dislodgement, phlebitis and extravasation. In severe cases, extravasation injury may lead to tissue necrosis, ulceration and long-term morbidity. The aim of this study was to determine the relative incidence of PIVC complications secondary to lower limb cannulation, compared to upper limb, in children with SNI. A single centre, retrospective, observational review was conducted. Patients with SNI, admitted at a tertiary paediatric centre over 6months between July and December 2022, were included. One-hundred fifty-five PIVC procedures were conducted in 110 children over the study period. Complications were more common in lower limb PIVCs (12/16, 75%) compared to upper limb (58/139, 42%), p = 0.01. Upper limb cannulation is preferred in children with SNI.
