About

Laryngeal nerve monitoring is performed to prevent intraoperative nerve damage in thyroidectomy operations. NIM-EMG intubation tube is used while monitoring the recurrent laryngeal nerve. Care should be taken when placing this tube. Ensure that the electrodes on the tube are in contact with the vocal cords. Both the macintosh laryngoscope and the videolaryngoscope can be used when inserting the NIM-EMG tube. The aim of our study is to compare these two intubation methods.

Full description

Anesthesiologists play a key role for the medications used for anesthesia and placement of the endotracheal tube in operations with intraoperative monitoring. While placing the NIM-EMG tube, the size of the endotracheal tube is very important so that the tube can contact the vocal cords.

The placement of the tube may change due to reasons such as movement of the neck during the operation. In addition, endotracheal tube placement may be problematic due to poor vision during direct laryngoscopy. Incorrect placement of the tube may result in equipment inoperability and increase the likelihood of injury to the recurrent laryngeal nerve.

Laryngoscopy is a term for tracheal intubation that provides visualization and evaluation of the larynx with its upper airway structures.

Until recently, direct laryngoscopy was considered the standard technique for endotracheal intubation. Recently, a wide variety of methods have been developed for endotracheal intubation. Video laryngoscopes are similar to direct laryngoscopes but provide laryngeal imaging with a small video chip on their blade. This imaging is superior compared to direct laryngoscopy. The aim of the study was to compare the use of direct laryngoscopy and video laryngoscopy in intubation with the NIM-EMG tube, which is routinely used in operations where the recurrent laryngeal nerve (RLN) may be damaged, in terms of intubation success, intubation time, tracheal intubation comfort, hemodynamic responses, surgical satisfaction, and complications that may develop after anesthesia or surgery.
