Ultrasound-Assisted Lumbar Puncture for Obese Pediatric Oncology
Patients: A Feasibility Study
Lumbar punctures (LPs) are performed frequently on children with
leukemia and lymphoma as part of the standard of care. They are
typically performed by pediatric oncology providers for both diagnostic
and therapeutic interventions with the aid of moderate or deep sedation.
Point-of-Care Ultrasound (POCUS) has emerged as a promising strategy to
aid in lumbar puncture procedures and has been found to be associated
with lower number of attempts, and higher success rates. We describe our
experience using POCUS to assist with LPs in a subgroup of pediatric
oncology patients identified to be procedurally difficult secondary to
obesity. This collaboration was well received and resulted in successful
LPs in most (8/9) cases. This is a promising modality to improve the
delivery of care and LP success in pediatric oncology patients.
