Course Objective:
To provide healthcare professionals with a comprehensive understanding of acid-base balance and electrolyte disturbances, and the strategies for diagnosing and correcting these abnormalities in a clinical setting. The course will enhance their ability to manage patients with complex metabolic and respiratory imbalances, ensuring effective treatment protocols and patient outcomes.
Target Audience:
Primary Target:
Healthcare professionals who manage critically ill patients and those with electrolyte and acid-base disturbances. This includes professionals in emergency, critical care, and internal medicine settings.
Basic Concepts of Acid-Base Balance:
Definition of acids, bases, and pH
The role of the bicarbonate buffer system in maintaining pH balance
The role of the kidneys, lungs, and buffers in maintaining homeostasis
Key Electrolytes and Their Roles:
Major electrolytes: Sodium (Na+), Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+), Chloride (Cl-), Phosphate (PO4-)
Electrolyte functions in maintaining cellular homeostasis, nerve function, and muscle contraction
Types of Acid-Base Disturbances:
Metabolic Acidosis and Alkalosis
Causes: Diabetic ketoacidosis (DKA), renal failure, diarrhea, etc.
Diagnostic workup (anion gap, chloride levels)
Management strategies
Respiratory Acidosis and Alkalosis
Causes: COPD, hypoventilation, hyperventilation, respiratory failure
Diagnostic strategies (ABG interpretation)
Management and correction strategies
Mixed Acid-Base Disturbances:
Identifying and managing mixed disorders (e.g., metabolic acidosis with respiratory alkalosis)
Diagnostic approach and clinical relevance
Case Discussions:
Electrolyte Imbalances:
Hypernatremia and Hyponatremia: Causes, symptoms, and management (e.g., dilutional hyponatremia, dehydration)
Hyperkalemia and Hypokalemia: Mechanisms, ECG changes, and treatment approaches (e.g., K+ replacement, sodium bicarbonate for hyperkalemia)
Hypercalcemia and Hypocalcemia: Causes, diagnostic workup, and management (e.g., calcium supplementation, calcium antagonists for hypercalcemia)
Hypomagnesemia and Hypermagnesemia: Impact on cardiovascular and neuromuscular function
Clinical Manifestations of Electrolyte Imbalances:
Arterial Blood Gas (ABG) Analysis:
Step-by-step interpretation of ABG results
Identifying primary disorders and compensatory mechanisms (e.g., Winter’s formula for metabolic acidosis)
Using ABG values to guide treatment
Electrolyte Panel Interpretation:
Understanding the significance of common laboratory tests (serum sodium, potassium, bicarbonate, chloride, and calcium levels)
How to interpret abnormal electrolyte values in the context of acid-base disturbances
Use of anion gap and delta gap in diagnosing mixed acid-base disorders
Clinical Scenarios:
Metabolic Acidosis Correction:
Indications for bicarbonate therapy and the correct administration
Strategies for managing DKA, lactic acidosis, and renal failure-related acidosis
Metabolic Alkalosis Correction:
Addressing the causes (e.g., vomiting, diuretic use)
Fluid and electrolyte replacement strategies (e.g., potassium chloride, saline)
Respiratory Acidosis Correction:
Ventilation support: Non-invasive vs. invasive ventilation for COPD, obstructive sleep apnea, and other causes
Using mechanical ventilation to correct respiratory acidosis
Respiratory Alkalosis Correction:
Management of hyperventilation, anxiety-induced alkalosis, and metabolic causes (e.g., sepsis)
Breathing techniques and pharmacological interventions (sedation, analgesia)
Sodium Imbalance:
Hypernatremia and hyponatremia correction strategies: Slow infusion rates, fluid management (IV fluids), sodium chloride, and vasopressin
Complications of rapid sodium correction (e.g., osmotic demyelination)
Potassium Imbalance:
Potassium supplementation for hypokalemia and management of hyperkalemia (e.g., calcium gluconate, sodium bicarbonate, insulin/glucose)
Electrocardiogram changes and emergency treatment
Calcium Imbalance:
Hypercalcemia management: IV fluids, bisphosphonates, and calcitonin
Hypocalcemia management: Calcium gluconate and correction strategies
Magnesium Imbalance:
Treating hypomagnesemia: IV magnesium sulfate and monitoring
Hypermagnesemia: Dialysis, calcium administration, and discontinuation of magnesium sources
Phosphate Imbalance:
Case Scenarios:
Electrolyte and Acid-Base Disturbance Correction Lab:
Hands-on practice with clinical simulation models for acid-base and electrolyte imbalance correction
Step-by-step correction of acid-base disturbances through fluid, electrolyte, and pharmacological interventions
Participants practice ABG interpretation and adjustment of treatments accordingly
Complex Case Simulations:
Participants manage real-world clinical cases involving severe electrolyte disturbances and acid-base disorders, with expert feedback and guidance
Emphasis on decision-making, monitoring, and adjusting therapies in response to clinical improvement or deterioration
Recap of Key Concepts:
Q&A Session:
Final Evaluation:
Learning Methods:
Lectures and Presentations: Expert-led discussions on theoretical knowledge and clinical application of acid-base and electrolyte management.
Case-Based Learning: Real-world case scenarios to illustrate key principles and encourage problem-solving.
Hands-On Simulation: Practical application of skills in managing acid-base and electrolyte disturbances using simulation equipment and clinical scenarios.
Interactive Q&A: Open floor for questions and troubleshooting challenges in clinical practice.
Key Learning Outcomes:
By the end of the course, participants will be able to:
Accurately diagnose and manage acid-base imbalances (metabolic and respiratory) using laboratory values and clinical presentation.
Correct electrolyte disturbances (sodium, potassium, calcium, magnesium, etc.) safely and effectively.
Interpret ABGs and electrolyte panels, and make clinical decisions based on the results.
Manage complex cases involving mixed acid-base disturbances and electrolyte abnormalities.
Apply evidence-based practices in the treatment of critically ill patients with electrolyte and acid-base disorders.
