In a patient with a motor vehicle accident and suspected bladder trauma, the initial nursing action must focus on identifying and managing immediate life threats. The ABCs (Airway, Breathing, Circulation) dictate that hemodynamic stability takes precedence over a definitive diagnosis of bladder injury.
1. Primary Survey Focus
- Circulation Assessment: The priority is to monitor for signs of hypovolemic shock, including tachycardia, hypotension, delayed capillary refill, pallor, and altered mental status. High-energy blunt trauma can cause significant retroperitoneal or intraperitoneal hemorrhage from vascular shearing, even without pelvic fractures.
- Hemorrhage Control: Be prepared to assist with massive transfusion protocols and application of a pelvic binder if pelvic instability is suspected, as this can tamponade bleeding.
2. Bladder Injury Considerations
- Catheterization Caution: Inserting a urinary catheter is not the first priority. A retrograde urethrogram must be performed before catheterization if a urethral injury is suspected (e.g., blood at the meatus, high-riding prostate). Blind insertion can convert a partial urethral tear into a complete one.
- Diagnostic Workup: Once the patient is hemodynamically stable, a CT cystogram is the gold standard for diagnosing bladder rupture. Gross hematuria is a key clinical indicator.
3. Ongoing Monitoring
- Continuously reassess vital signs and urine output (once a catheter is safely placed) to evaluate response to resuscitation.
- Monitor for abdominal distension and increasing bladder pressure, which could indicate abdominal compartment syndrome, a secondary complication of massive fluid shifts and bleeding.
