Overview

  • If a patient presents with a full, bulging abdomen, percussion of the flanks can provide valuable information to diagnose ascites. The presence of shifting dullness has 83% sensibility and 56% specificity to diagnose ascites. A patient without flank dullness has less than 10% chance of having ascites.[1]

Physical Examination

Appearance of the patient

  • Patients with peritonitis are usually ill-appearing, initially they appear alert, restless and irritable.They may later become apathetic and delirious.
  • They are often noticed lying quietly supine,on the bed with the knees flexed and with frequent limited intercostal respirations because any motion intensifies the abdominal pain.

Vital signs

Temperature

  • Hyperthermia (temperatures as high as 42° C) is a sign of infection and hypothermia (temperatures as low as 35° C) indicates septic shock.
  • Hypothermia is a grave sign,seen late in the course of the disease in patients with on-going intra-abdominal sepsis or septic shock.

Pulse

  • Tachycardia with weak, thready peripheral pulses represents decreased effective circulating blood volume,indicating a stage of shock later in the disease.

Respiration

  • Tachypnea

Bloodpressure

Skin

Eyes

Neck

Heart

Lungs

Neurologic

Following may be noticed when spontaneous bacterial peritonitis complicates or due to underlying liver or renal failure.

Abdomen

  • Usually tense due to ascites
  • Marked abdominal tenderness to palpation is present, usually maximum over the organ in which the process originated.
  • Direct and referred rebound tenderness is almost always present and signifies the irritation of the parietal peritoneum.
  • Muscular rigidity of the abdominal wall produced by voluntary guarding and reflex muscular spasm is almost always present.
  • Hyper-resonance on percussion if present,indicates the gaseous dissention of the intestine.
  • Shifting dullness on percussion is noted in patients with ascites, but may be painful due to infection.
  • Pneumoperitoneum, which results from gas/air in the peritoneal cavity, results usually from a ruptured hollow viscus produces liver dullness to percussion
  • Bowel sounds vary along the course of peritonitis, are initially hypoactive, and may disappear later.Absence of bowel sounds may be the only manifestation of peritonitis in some patients, and a high index of suspicion is necessary
