Study Notes
Hemodynamic Disorders Module Session 6
- Hemodynamic disorders are a focus of this session
- Dr. Adnan Anwer, an M.B.Ch.B., F.I.B.M.S. (hematopath), led the small group discussions
Case 1: Coronary Artery Obstruction
- Observation A: Normal coronary artery
- Observation B: Coronary artery from a 60-year-old man who died of severe chest pain. Shows a thrombus (blood clot) within the lumen.
- Observation C: Transverse section of a heart affected by coronary artery obstruction. Reveals myocardial infarction.
- Luminal Deposition Causes (Case B): Atherosclerosis is a key contributor
- Effects on the Heart (Case C): Angina and myocardial infarction (ischemia) are potential outcomes
- Treatment Options: Anti-platelet drugs (aspirin) and angioplasty. Thrombectomy is another possible treatment
Case 2: Pleural Effusion
- Patient Details: 68-year-old man with hypertension, presenting with dyspnea and pleural effusion (hemothorax).
- Investigations: X-ray, ultrasound, and thoracentesis (pleural fluid analysis) are needed.
- Pleural Fluid Significance: Analysis aids in pinpointing the cause of effusion, differentiating between transudate and exudate types, and guiding treatment.
- Case 2 Pleural Fluid Findings: Protein level of 2 gm/dL, few cellularity, and negative Gram stain and TB tests indicate a transudate type of pleural effusion. (non-inflammatory)
- Causes of Transudate Pleural Effusion: Imbalances in hydrodynamic pressure, particularly increased capillary pressure, are the key causes
Case 3: Pleural Effusion
- Patient Details: 32-year-old female with fever, pleuritic chest pain, dyspnea and pleural effusion.
- Pleural Fluid Findings: Turbid yellow color, protein level of 6 gm/dL, many cells (mostly neutrophils), and positive bacterial culture in pleural fluid indicate an exudative type of effusion.
- Exudative Causes: Elevated vascular permeability and lymphatic obstruction are implicated.
Case 4: Pulmonary Embolism (PE)
- Patient Details: 64-year-old male with a history of hip surgery 20 days prior, experiencing dyspnea, pleuritic chest pain, and hypoxia. Clinically diagnosed with DVT (deep vein thrombosis).
- Differential Diagnosis: The patient's symptoms need to be differentiated, particularly from causes that are not PE.
- PE Risk Factors (Case 4): Immobility after hip surgery is a significant factor.
- Diagnosis Confirmation: CXR (chest X-ray), duplex Doppler of legs, ECG, arterial blood gas analysis, D-dimer levels, and CT pulmonary angiography can be used to confirm or rule out PE.
- Treatment: The exact treatment is not mentioned in this document.
Case 5: Intestinal Infarction
- Patient Details: 70-year-old male presenting with severe abdominal pain that escalated to shock, with subsequent death despite surgery.
- Intestinal Appearance: The intestine shows congestion and hemorrhagic infarction as a clinical presentation.
- Cause of Symptoms: The cause is an infarction to the intestines, with possible dual blood supply issues.
- Congestion Cause: The congestion can happen if blood supply is restricted to the intestine
Types of Shock
- The subsequent cases discuss different types of shock scenarios
- Cases focus on identifying the shock type based on patient characteristics and symptoms, such as hypotension, tachycardia, presence of fever, or altered mental status and skin condition.
