Q

What iron studies are seen in iron deficiency anaemia?

A

Low transferrin saturation, low ferritin, high TIBC

Low transferrin saturation can be thought of as fewer binding spots taken up by iron, low ferritin can suggest less iron has been stored, and a high TIBC means there are more binding spots free for iron to take up, therefore suggesting low iron in the body.

Q

How does hypophosphataemia present?

A

May result in significant muscle weakness, including myocardial muscle (→ cardiac failure) and the diaphragm (→ respiratory failure).

Cardiac Dysfunction: Hypophosphatemia can impair myocardial contractility, leading to heart failure. It may also cause arrhythmias due to its role in maintaining normal cellular electrophysiology.

Respiratory Failure: Phosphate is essential for ATP production, necessary for respiratory muscle function. Severe hypophosphatemia can lead to muscle weakness, including the diaphragm and intercostal muscles, potentially resulting in acute respiratory failure.

Neurological Complications: These can range from confusion and seizures to coma, attributable to disturbed ATP metabolism in the central nervous system.

Haematological Effects: Reduced 2,3-diphosphoglycerate levels in erythrocytes affect oxygen release from haemoglobin, leading to tissue hypoxia. Hypophosphatemia can also result in hemolysis.

Rhabdomyolysis: Phosphate depletion impairs ATP production in muscles, which can lead to muscle breakdown and rhabdomyolysis.

91
When to use CPAP or BIPAP in an exacerbation of COPD?
CPAP maintains open airways and supports oxygenation through constant air pressure delivery but does not assist in carbon dioxide removal as effectively as BiPAP, which mimics natural breathing patterns and thus aids both in oxygenation and CO2 elimination. CPAP is more suited for managing type 1 respiratory failure—defined by a PaO2 less than 8 kPa with normal PaCO2 levels—as seen in conditions such as acute heart failure or moderate-to-severe obstructive sleep apnoea. This patient exhibits respiratory acidosis, characterised by a pH of less than 7.35 and a PaCO2 greater than 6 kPa, alongside type 2 respiratory failure, indicated by normal or reduced PaO2 with a PaCO2 exceeding 6 kPa. Given that these conditions have persisted despite optimal medical management, non-invasive ventilation (NIV) is warranted. The patient's current ventilatory support is inadequate for the elimination of excess CO2. BiPAP is the most frequently utilised form of NIV for acute exacerbations of chronic obstructive pulmonary disease (COPD), as it prevents the rebreathing of exhaled gases, facilitates the reduction of CO2 retention, and more effectively ameliorates acid-base disturbances compared to continuous positive airway pressure (CPAP). Thus, BiPAP stands as the preferred modality for managing type 2 respiratory failure in this context. A pH below 7.25 would necessitate consideration for either intubation or admission to a high-dependency unit (HDU); however, this patient's clinical parameters do not indicate such measures.
92

Severe cellulitis should be treated with co-amoxiclav, cefuroxime, clindamycin or ceftriaxone
