Point-of-Care Ultrasound for Obstetrics: Basics and Introductory Chapter

Detailed knowledge and appropriate use of point-of-care ultrasound (POCUS) have become a necessity in numerous medical subspecialties. This chapter includes a basic overview of POCUS and its utilization in obstetric anesthesiology. It discusses the basics of clinical ultrasound physics (i.e., sound waves, frequency, wavelength) and ultrasound machine (i.e., knobology, probes, and modes). It then focuses on POCUS capabilities, indications, advantages and limitations in clinical practice. A comprehensive list of currently available, clinically proven POCUS resuscitation protocols is also summarized. Additionally, the use of POCUS in obstetric anesthesiology practice is specifically highlighted. The process of obtaining POCUS certification is reviewed as well as current existing courses. Ongoing challenges faced by the societies to ensure competency-based assessments are discussed.
