From the scheme given below, choose the appropriate order of priorities in the management of a patient with polytrauma: 1. Control of external haemorrhage 2. Intravenous infusion and transfusion 3. Maintenance of patent airway 4. Relief of a tension pneumothorax. 5. Splinting of fractures.
**Core Concept**
The management of a patient with polytrauma involves a systematic approach to address life-threatening injuries and prevent further harm. The order of priorities is critical to ensure the best possible outcome.
**Why the Correct Answer is Right**
The correct order of priorities is based on the ABCDE approach, which stands for Airway, Breathing, Circulation, Disability, and Exposure. In the context of polytrauma, the initial steps involve ensuring a patent airway to prevent hypoxia and cardiac arrest. This is followed by the relief of tension pneumothorax, which is a life-threatening condition that requires immediate attention. Control of external hemorrhage is essential to prevent hypovolemic shock, while intravenous infusion and transfusion are critical for maintaining circulation. Splinting of fractures is important for preventing further injury, but it is not as immediately critical as the other steps.
**Why Each Wrong Option is Incorrect**
**Option A:** While controlling external hemorrhage is essential, it is not the first priority in the management of polytrauma. This is because a patent airway is necessary to prevent hypoxia and cardiac arrest.
**Option B:** Intravenous infusion and transfusion are critical for maintaining circulation, but they are not the first priority in the management of polytrauma. This is because a patent airway and relief of tension pneumothorax are more immediately critical.
**Option C:** Relief of tension pneumothorax is a critical step in the management of polytrauma, but it is not the first priority. This is because ensuring a patent airway is necessary before attempting to relieve a tension pneumothorax.
**Option D:** Splinting of fractures is an important step in the management of polytrauma, but it is not as immediately critical as the other steps. This is because a patent airway, relief of tension pneumothorax, and control of external hemorrhage are more critical for preventing further harm.
**Clinical Pearl / High-Yield Fact**
The ABCDE approach is a critical tool for managing patients with polytrauma. Remembering the order of priorities as Airway, Breathing, Circulation, Disability, and Exposure can help guide treatment and prevent further harm.
**Correct Answer: C.**
