ABSTRACT
This chapter provides information for performing fontanelle tap. It begins with a case scenario of a 4-week-old male infant who is presented with germinal matrix hemorrhage and ventricular dilation. The chapter then includes details on indications, contraindications, and information about supplies, positioning and technique. Pearls and pitfalls are also incorporated, providing additional insights and practical advice not always available in other textbooks or articles. Reviewing ultrasound images helps the clinician visualize the size of the ventricles. Marking the midline helps orient the clinician to the course of the superior sagittal sinus.
