Study Notes
Abdominal Trauma: Etiology and Pathophysiology
- Abdominal trauma results from blunt or penetrating injuries.
- Common injuries include lacerations to the liver, spleen, and mesentery, diaphragm rupture, bladder rupture, great vessel tears, renal/pancreatic damage, and stomach/intestinal ruptures.
- Blunt trauma often arises from MVA, direct blows, or falls, which may not manifest as obvious wounds. It involves compression (e.g., direct blows) or shearing (e.g., rapid deceleration in crashes).
- Penetrating trauma involves gunshot or stabbing wounds creating obvious open wounds.
- Injuries to solid organs (liver, spleen) lead to potentially profuse bleeding and hypovolemic shock.
- Damage to hollow organs (bladder, stomach, intestines) can cause their contents to spill into the peritoneal cavity, risking peritonitis.
- Abdominal compartment syndrome (ACS) may develop due to increased abdominal pressure from factors like internal bleeding or edematous organs.
- This high pressure hinders breathing, potentially causing respiratory failure, reduces cardiac output, venous return, and organ perfusion, potentially leading to renal failure.
Abdominal Trauma: Clinical Manifestations
- Abdominal trauma often presents with associated injuries like rib fractures, pelvic fractures, spinal injuries, and thoracic injuries.
- Seatbelt injuries in MVA can cause blunt trauma to abdominal organs (intestines, pancreas) by pressing them against the spinal column.
- Common clinical manifestations include: guarding/splinting of the abdominal wall (peritonitis), a hard, distended abdomen (intra-abdominal bleeding), decreased/absent bowel sounds, abdominal abrasions/bruising, abdominal pain, hematemesis/hematuria, and signs of hypovolemic shock.
- Bruising around the umbilicus (Cullen sign) or flanks (Grey Turner sign) suggests retroperitoneal hemorrhage.
- Absence of bowel sounds indicates peritonitis. Diaphragm rupture can cause bowel sounds to be heard in the chest.
- Auscultation for bruits can indicate arterial damage.
Abdominal Trauma: Diagnostic Studies
- Initial diagnostics involve a baseline CBC and urinalysis.
- Hemoglobin/hematocrit may appear normal in the early stages but will show deficiencies after fluid resuscitation.
- Blood in the urine suggests potential kidney/bladder damage.
- Further tests may include arterial blood gases, prothrombin time, electrolytes, BUN, creatinine, and type/crossmatch.
- Abdominal CT scans and focused abdominal ultrasound are common methods, but the patient must be stable for CT.
- Diagnostic peritoneal lavage can identify fluids like blood, bile, intestinal contents, and urine within the peritoneal cavity.
Abdominal Trauma: Interprofessional and Nursing Care
- Emergency management involves volume expansion (fluids/blood) for hypotensive patients.
- Nasogastric (NG) tubes with low suction can decompress the stomach and prevent aspiration.
- Frequent monitoring of vital signs, consciousness, oxygen saturation, and urine output is crucial to detect deterioration.
- Conservative management and surgical decisions are based on clinical findings, diagnostic results, and patient response.
- Impaled objects should be stabilized with dressings, NOT removed, until appropriate care is available.
Chronic Abdominal Pain: Overview
- Chronic abdominal pain can originate from the abdomen itself or be referred pain from related nerve supplies.
- Pain is often described as dull, aching, and diffuse.
- Common causes include IBS, peptic ulcers, chronic pancreatitis, hepatitis, PID, adhesions, and vascular insufficiency.
- Diagnosis involves a thorough history, detailed pain characteristics (severity, location, duration, onset), and frequency and factors influencing the pain.
- Diagnostic tools may include endoscopy, CT scans, MRI, laparoscopy, and barium studies.
- Treatment is tailored to the underlying cause of the chronic pain.
Abdominal Trauma: Assessment (Summarized)
- Blunt/Penetrating Trauma - details for each
- Abdominal/GI Findings - assessment includes distention, pain, rigidity, bowel sounds, vomiting, blood in stool/urine.
- Hypovolemic Shock - symptoms such as low blood pressure, racing heart rate, reduced consciousness, rapid breathing are detailed.
- Surface Findings - observations for abrasions, bruising, impaled objects, open wounds are mentioned.
- Initial Care/Ongoing Monitoring - steps for initial care, including airway/breathing/circulation management, bleeding control, IV access, blood work, and stabilization, along with monitoring of vital signs, consciousness level, O2 saturation, and urine output.
