A 55-year-old man is evaluated in the surgical intensive care unit on postoperative day 3 following an extensive bowel resection. He just underwent right internal jugular central venous catheter placement for the administration of total parenteral nutrition. Ten minutes after the procedure, he develops sudden, severe dyspnea and right-sided chest pain. Vital signs show a temperature of 37.1°C (98.8°F), heart rate of 132/min, blood pressure of 85/50 mmHg, and oxygen saturation of 87% on room air. Physical examination reveals absent breath sounds on the right hemithorax and distended neck veins. Arrange the following steps in the most appropriate chronological sequence for the immediate management of this patient.
- 1Administer 100% supplemental oxygen and ensure airway patency.
- 2Perform immediate needle thoracostomy for pleural space decompression.
- 3Insert a tube thoracostomy (chest tube) for definitive continuous drainage.
- 4Obtain a portable chest radiograph to evaluate tube placement and lung expansion.
Cevap
The correct sequence is to first administer 100% supplemental oxygen, followed immediately by needle thoracostomy, then insert a tube thoracostomy, and finally obtain a portable chest radiograph.
The patient's presentation of severe hypotension, tachycardia, absent breath sounds, and distended neck veins immediately following central line placement is classic for an iatrogenic tension pneumothorax. Management strictly follows trauma and resuscitation algorithms: first, secure the airway and provide 100% oxygen. Because the patient is hemodynamically unstable, the tension pneumothorax must be treated presumptively with an immediate needle thoracostomy (decompression). Once the life-threatening tension is relieved, a definitive tube thoracostomy (chest tube) is placed. Finally, a portable chest radiograph is obtained to confirm the resolution of the pneumothorax and verify proper tube placement.
Adım Adım Çözüm
Anahtar Kavram
Tension pneumothorax is a clinical diagnosis requiring immediate needle decompression prior to radiographic imaging in any hemodynamically unstable patient.
