â– LECTURE OVERVIEW: Acute Cholecystitis is an inflammatory condition of the gallbladder, most commonly triggered by a gallstone obstructing the cystic duct (calculous cholecystitis).
â– THE CASCADING METABOLISMS:
1. Cystic Duct Blockage: A stone blocks the cystic duct.
2. Mucosal Distension: Secreted mucus cannot drain, causing gallbladder distension and severe wall tension.
3. Mucosal Ischemia: Mural tension compresses mucosal capillaries, causing ischemia.
4. Bacterial Translocation: Ischemia compromises the mucosal barrier, promoting bacterial translocation (commonly E. coli, Klebsiella) that worsens inflammation.
5. Peritoneal Irritation: The inflamed gallbladder rubs against the adjacent parietal peritoneum of the anterior abdominal wall.
â– CLINICAL COMPLICATIONS:
Delayed or incomplete treatment triggers cascading systemic strain, involving downstream organ failure, severe metabolic imbalances, or progressive tissue necrosis.
â– CRITICAL CARE MANAGEMENT PROTOCOL:
Continuous cardiopulmonary and metabolic monitoring is paramount during acute decompensation. Maintain strict control over fluid ratios and oxygenation parameters.

🌟 Dynamic Clinical Key:
Murphy's sign is elicited by palpating the right upper quadrant under the costal margin. As the patient takes a deep breath, the diaphragm descends, pushing the inflamed gallbladder against the examiner's fingers. This causes localized pain, prompting the patient to abruptly halt inspiration (inspiratory arrest). Early aggressive resuscitation is key to prevent irreversible multi-system organ dysfunction. Do not delay airway protection and resuscitation maneuvers for low-priority imaging.
