A nurse is caring for a newborn with bladder exstrophy. Which nursing intervention is the highest priority in the immediate postoperative period following primary closure?

Maintaining strict sterile technique with urinary catheters is the highest priority to prevent infection and protect the surgical repair. Other options are not appropriate in the immediate postoperative period.

Understanding the Priority: Protecting the Exposed Bladder Mucosa

In the immediate newborn period, the most critical nursing priority for an infant with bladder exstrophy is to preserve the integrity of the exposed bladder mucosa. The bladder plate is open to air and directly visible on the lower abdominal wall, making it extremely vulnerable to mechanical trauma, drying, and infection. The rationale for the correct intervention is grounded in the pathophysiology of the defect and the goal of early surgical repair.

Why a Saline-Moistened, Non-Adherent Dressing is the Top Priority

The correct intervention is to cover the exposed bladder with a sterile, non-adherent dressing moistened with normal saline. This approach directly addresses the three primary threats to the exposed tissue: desiccation, trauma, and bacterial contamination.

- Prevention of Desiccation: The bladder mucosa is a mucous membrane designed to be in a continuously moist environment. Upon exposure to air, it rapidly loses moisture, leading to cellular death and tissue breakdown. A saline-moistened dressing maintains a physiologic environment that keeps the mucosa viable. This is fundamental, as the literature emphasizes that management and outcomes are significantly better when care begins in the newborn period, with the ultimate goal being successful primary repair ^[2]. A desiccated, non-viable bladder plate compromises the surgical outcome.
- Atraumatic Protection: A non-adherent dressing is essential. Any dressing that sticks to the delicate mucosa will cause epithelial stripping and bleeding upon removal, creating portals for infection and further tissue damage. The goal is to protect the bladder plate as a pristine tissue bed for future surgical reconstruction, a concept central to the complete primary repair of bladder exstrophy (CPRE) ^[1].
- Infection Control: The exposed mucosa lacks the protective barrier of intact skin. A sterile dressing acts as a physical barrier against environmental pathogens, reducing the risk of cystitis. The case report of a neglected presentation highlights that a contracted, infected bladder plate (cystitis) complicates management and forces adaptation of the usual surgical protocol ^[2]. Preventing infection from the moment of birth is a direct nursing action to avoid this complication.

Analysis of Incorrect Options

- Option 1 (Apply a sterile petroleum jelly gauze): While sterile, petroleum jelly-based products can be occlusive and difficult to remove completely without friction. The priority is a non-adherent, moist environment, which is more reliably and safely achieved with a saline-moistened dressing. The occlusive nature does not provide the same level of physiologic moisture and may trap exudate if any irritation begins.
- Option 2 (Insert a urinary catheter): Urinary catheterization in classic bladder exstrophy is technically challenging and potentially traumatic to the open, abnormal bladder plate and urethral anatomy. It is not a first-line nursing intervention immediately after birth. The immediate focus is protecting the exposed tissue, not instrumenting it. The case report of a successful primary repair describes a course of appropriate medical care and nursing without immediate mention of catheterization as the first step, with the infant being discharged without urinary retention ^[1].
- Option 4 (Position the infant prone): Prone positioning would place direct pressure and friction on the exposed, extremely fragile bladder mucosa, causing trauma and contamination. The infant is kept supine with the dressing in place, and a diaper is typically not applied over the dressing to avoid pressure and contamination. The goal is to keep all mechanical forces off the bladder plate.

The initial nursing action is a temporizing, protective measure that bridges the time from birth to definitive surgical planning. Maintaining a viable, moist, and infection-free bladder plate with a sterile saline-moistened non-adherent dressing is the foundational step upon which successful long-term outcomes, such as the achievement of continence and prevention of hydronephrosis described in follow-up care, are built ^[1].
