Which of the following techniques is currently recognized as the standard practice for external laryngeal manipulation?

The recognition of external laryngeal manipulation (ELM) as the standard practice for external laryngeal manipulation stems from its efficacy in improving the visualization of the vocal cords during intubation, particularly in difficult airway situations. ELM involves applying pressure to the thyroid cartilage, effectively aligning the airway structures, and aiding in the placement of the endotracheal tube. This technique is particularly valuable in managing patients where standard intubation may be obstructed due to anatomical issues or trauma.

While other techniques, such as the Sellick's maneuver, BURP (Backward Upward Rightward Pressure), and the jaw thrust maneuver, have their specific uses in airway management, ELM's targeted application and focus on enhancing laryngeal visualization is what establishes it as the recognized standard practice in various clinical guidelines. This makes it a critical skill for practitioners in critical care and emergency settings, as successful airway management is paramount for patient survival.
