A nurse is caring for a newborn diagnosed with myelomeningocele at the L3-L4 level. Which nursing intervention should be the highest priority immediately after birth?

The highest priority is protecting the exposed neural tissue from infection and trauma by covering the defect with sterile saline-soaked gauze. Other interventions like prone positioning or ROM exercises are important but secondary or contraindicated immediately after birth.

Immediate Priority in Myelomeningocele Care

The highest priority intervention immediately after birth for a newborn with a myelomeningocele at the L3-L4 level is to cover the defect with sterile saline-soaked gauze. The core pathophysiological concern is the exposure of neural elements, specifically the spinal cord and meninges, to the external environment. This open defect creates a direct portal for infection, such as meningitis, and allows for rapid fluid loss leading to desiccation of the neural tissues. The sac is extremely fragile and vulnerable to rupture, which would dramatically increase the risk of central nervous system infection and permanent neurological damage.

The pre-surgical management simulation model described by Rosen and Angert underscores the critical nature of immediate, protective covering of the defect as a foundational step in delivery room management ^[1]. The procedure involves applying a sterile, non-adherent dressing moistened with warm, sterile normal saline. This intervention achieves two essential goals: it creates a physical barrier against bacterial contamination, and it prevents the delicate neural tissues from drying out. The dressing must be kept moist, and the infant is subsequently positioned to avoid any pressure on the sac, but the act of covering it takes temporal precedence to mitigate the immediate risk of infection and tissue injury ^[1]. While other interventions are important, they are secondary to protecting the exposed spinal cord from the moment of birth.

- Option 1 (Prone positioning) is a crucial intervention to prevent sac rupture and pressure injury, but it is performed in conjunction with or immediately after the sterile dressing is applied. The dressing itself must be in place first to protect the defect when the infant is positioned.
- Option 2 (Range of motion exercises) is a long-term rehabilitative need to address potential contractures from paralysis but is not an immediate life-saving priority in the delivery room.
- Option 3 (Assessing for increased intracranial pressure) is a critical ongoing assessment because myelomeningocele is frequently associated with Arnold-Chiari II malformation and hydrocephalus. However, the initial assessment for signs like a bulging fontanel or altered neurological status occurs after the immediate physical protection of the exposed defect has been secured. The immediate threat to life and future function from infection and tissue desiccation is more time-sensitive.
