[2025-10-02T10:12:50.235850] [PI reasoning] **Preparing for thoracotomy**

I need to answer a multiple-choice question regarding a polytrauma patient who has a massive hemothorax due to recent chest tube drainage. Given that the immediate drainage reached 1500 mL, it indicates the need for an emergency thoracotomy. The guidelines specify that an initial output over 1500 mL or persistent drainage of over 200 mL/hr warrants this step. So, my next task is to prepare for the thoracotomy and gather reliable citations from trauma guidelines. Let's get started!
