Muscular defense

Muscular defense

Muscular defense refers to the involuntary contraction of the muscles in the abdomen in response to palpation or pressure, which is often a sign of peritoneal irritation or inflammation. It is characterized by a tense and rigid abdomen, which can be painful to the touch. The absence of muscular defense during physical examination may indicate a lack of peritoneal irritation or inflammation.From: Clinical Diagnosis and Management of Gynecologic Emergencies [2020], A rare case of non-traumatic acute intraabdominal hemorrhage: ruptured superior mesenteric artery aneurysm [2018]

Stage III: Acute. Bleeding after the abortion at least drains in part into the abdominal cavity. The patient experiences peritoneal irritation and muscular defense of the abdomen during palpation. Vaginal bleeding becomes more severe and may even start to clot. Vaginal examination will now reveal a retrouterine hematocele, and the patient feels a distinct tenderness on cervical motion. During abdominal palpation, a distended tube and a peritubal hematoma may be felt.

A 37-year-old male patient presented with the chief complaint of cramping and diffuses abdominal pain with sudden onset. Physical examination revealed diffuse abdominal tenderness with no muscular defense and rebound tenderness. Intestinal sounds were normoactive. Oral intake was stopped since patient was having increased abdominal pain episodes during oral feeding. An abdominal Doppler ultrasound was performed and showed an aneurysmal lesion of 76 × 47 mm at the proximal part of the SMA. The abdominal CT confirmed a pseudo-aneurysm at the proximal part of SMA, and showed surrounding fatty infiltration.
