Trial Outcomes & Findings for Suction Catheter as a Guide for Nasotracheal Intubation Under General Anesthesia (NCT NCT05717907)

NCT ID: NCT05717907

Last Updated: 2024-12-20

Results Overview

The video from video laryngoscope will be recorded at the moment during and immediately after successful intubation, which will be later reviewed by primary outcome assessor that not involved in the procedure. Accounting for only bleeding observed at posterior pharyngeal area, which originate from trauma from attempt to pass ETT through the nasal passage into the pharynx. Assessment of bleeding will be scored at the most severe bleeding state observed from inserting to the removal of video laryngoscope after successful intubation. The extent of bleeding will be graded as: "Grade 0" = no bleeding "Grade 1" = blood-stained tube and/or cuff "Grade 2" = blood-stained posterior pharyngeal wall (traces or streak of blood) "Grade 3" = blood pooling at posterior pharyngeal wall

Guided Group
use suction catheter guided endotracheal tube through the nasal passage suction catheter: a suction catheter will be first inserted through the ETT so that about 10 cm of the catheter was protruding from the distal end of the tube. The tip of the catheter is then inserted through the selected nostril until it passes to the pharynx. If resistance is felt to the passage of catheter, the other nostril will be tried. The nostril with less resistance to the catheter passage will be chosen for the completion of the procedure. The Endotracheal tube is then advance over the catheter through the nasal passage while holding the catheter proximal to the tube to prevent its advancement with the tube. After the tube tip reach to the pharynx, the suction catheter is withdrawn and tracheal intubation will be completed.

SECONDARY outcome

Timeframe: measured immediately after successful intubation

Ease of navigation during advancement of tube though the nasal passage, will be recorded as "Smooth" = ETT meet no resistance, no need to adjust the tube "Slight resistance" = ETT meet the resistance and has to be manipulated more than once "Impinged" = ETT cannot pass through and need to move to another nostril

OTHER_PRE_SPECIFIED outcome

Timeframe: measured immediately after successful intubation

* Control group: starting when the tip of the ETT just enter the anterior nares until the tip of the ETT just pass the posterior nares and entered the pharynx * Guided group: starting when the tip of the guiding suction catheter just entered the anterior nares until the tip of the ETT passed the posterior nares, then entered the pharynx and the guiding catheter was completely removed from the ETT. The outcome will be recorded in "unit of seconds"
