Which symptom should prompt immediate assessment in a postoperative patient?

Laryngeal stridor is a critical symptom that indicates potential airway obstruction or respiratory distress, which can occur due to postoperative complications such as swelling, hematoma, or allergic reactions. Given the importance of maintaining a patent airway and adequate ventilation, the presence of stridor requires immediate assessment and intervention. This symptom can rapidly progress to life-threatening situations if not addressed promptly. In the postoperative setting, particularly following surgeries involving the neck or throat, any signs of airway compromise necessitate urgent evaluation to ensure that the patient's airway is secure and to implement appropriate measures.
