Nausea and Vomiting: Understanding the Causes
When it comes to the peritoneum, a specific part of it receives nerves at the submesothelial level. This particular region happens to be highly sensitive to noxious stimuli, which can lead to friction and inflammation. One common cause of inflammation in the peritoneum is hemoperitoneum, which affects the surrounding tissues and organs, including the gastrointestinal tract. As a result, the neurons responsible for the sensation of nausea and the reflex of vomiting become activated.
Kehr’s Sign: An Unexpected Symptom of Hemoperitoneum
Hemoperitoneum, a condition characterized by the presence of blood in the abdominal and pelvic regions, often causes pain and tenderness. However, there is another symptom that may come as a surprise – shoulder pain. Referred by the phrenic nerve, Kehr’s sign manifests as acute pain in the shoulder, which can be traced back to the diaphragm. This sensation is typically triggered by the presence of a foreign substance in the peritoneum. Known as a classic symptom of a splenic injury that has resulted in a bleeding laceration, Kehr’s sign serves as an important indicator for medical professionals.
