No results posted yet for this study

Summary

The goal of this study is to determine whether omitting tracheal suctioning immediately prior to extubation is non-inferior to routine tracheal suctioning with respect to early postoperative oxygenation among adult surgical patients (aged 18-90 years, American Society of Anesthesiologists \[ASA\] physical status I-III) undergoing elective surgery under general anesthesia with endotracheal intubation.

The study addresses the following questions:

* Primary outcome (non-inferiority):
* Is the risk of postoperative desaturation (oxygen saturation \[SpO₂\] \<92% within 60 minutes after extubation) in the no-suction group not worse than in the routine-suction group by more than 10 percentage points?
* Secondary outcomes (superiority):
* Does omitting tracheal suctioning reduce postoperative cough severity and sore throat?
* Does omitting tracheal suctioning avoid increasing extubation-related adverse events?

Participants will be randomly assigned (1:1) to one of two groups:

* Routine suctioning (SUC): Endotracheal suctioning plus oropharyngeal suctioning immediately before extubation
* No suctioning (NON-SUC): Oropharyngeal suctioning only, without endotracheal suctioning

All participants will receive standard anesthetic care and postoperative monitoring in the post-anesthesia care unit (PACU) for 60 minutes. Follow-up for airway symptoms and patient satisfaction will be conducted at 24 hours after surgery.

Conditions

  • Sore Throat
  • Hypoxia
  • Airway Obstruction, Postoperative
  • Cough, Postoperative

Interventions

PROCEDURE

Routine Endotracheal Suctioning

Endotracheal suctioning performed immediately prior to extubation using standard suction pressure and technique. Oropharyngeal suctioning was also performed according to routine clinical practice.

PROCEDURE

Omission of Endotracheal Suctioning

Oropharyngeal suctioning only was performed prior to extubation. No suction catheter was inserted into the trachea.
