Ultrasound Findings in a Neonate During Anaphylactic Reaction to Total Parenteral Nutrition: A Case Report.

Total parenteral nutrition (TPN) is the intravenous delivery of nutrients and is commonly used in the Neonatal Intensive Care Unit (NICU). Hypersensitivity reactions to parenteral nutrition have seldom been described in the literature. Anaphylaxis is a potentially life-threatening emergency condition that can progress rapidly and involves multiple organ systems. We report a case of anaphylaxis due to TPN in a neonate with observed ultrasound findings during the acute episode never reported in the literature before.
