Lessons learned measuring peripheral venous pressure waveforms in an anesthetized pediatric population.

Objectives: The purpose is to describe our institution's experience with collecting peripheral venous pressure (PVP) waveforms using a standard peripheral intravenous catheter in a pediatric patient under general anesthesia. Approach: PVP waveforms, piezoelectric monitoring, arterial blood pressure recording, and electrocardiogram (EKG) tracings were collected from patients undergoing cranial vault reconstruction for craniosynostosis. Data was obtained prospectively in a continuous manner from time of patient final positioning to closure of incision. Description of the technical aspects are discussed. Main Results: The waveform data collection was affected by the following: use of electrocautery, location of electrocautery in relation to PVP monitor, and movement of the operating room table. Significance: PVP waveforms can be collected in a pediatric patient undergoing general anesthesia with accurate data acquisition. Additionally, the set-up used also allows for accurate collecting of piezoelectric monitoring, arterial blood pressure recording, and EKG tracings in real time.
