About this study
Official title: Comparison of Endotracheal Tube Suctioning Versus No Suctioning During Emergence From General Anesthesia With Endotracheal Intubation: A Randomized, Single-Blind Study
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:
Read more
- 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Routine Endotracheal SuctioningProcedure or surgery
Also called SUC
Endotracheal suctioning performed immediately prior to extubation using standard suction pressure and technique. Oropharyngeal suctioning was also performed according to routine clinical practice.
Omission of Endotracheal SuctioningProcedure or surgery
Also called NON-SUC
Oropharyngeal suctioning only was performed prior to extubation. No suction catheter was inserted into the trachea.
| Study group | Role | What they receive |
|---|---|---|
| Routine Endotracheal Suctioning (SUC) | Active comparator | Participants in this arm received routine endotracheal suctioning immediately prior to extubation, performed using standard suction pressure and technique. Oropharyngeal suctioning was also performed according to usual clinical practice. Receives: Procedure: Routine Endotracheal Suctioning |
| Omission of Endotracheal Suctioning (NON-SUC) | Experimental | Participants in this arm received oropharyngeal suctioning only prior to extubation. No suction catheter was inserted into the trachea. Standard anesthetic care and monitoring were provided as per routine practice. Receives: Procedure: Omission of Endotracheal Suctioning |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of postoperative desaturation after extubation
Proportion of participants who develop desaturation, defined as peripheral oxygen saturation (SpO₂) <92% at any time within the first 60 minutes after extubation.
Measured: First 60 minutes after extubation
Secondary outcomes (6)
Incidence and severity of postoperative coughing
Incidence and severity of postoperative coughing within the first 60 minutes after extubation, assessed using the modified Minogue scale. Severity is recorded as the highest coughing score observed during the assessment period.
Measured: First 60 minutes after extubation
Severity of sore throat during swallowing
Severity of sore throat during swallowing within the first 60 minutes after extubation, assessed using a 0-10 numerical rating scale (NRS). The outcome is recorded as the highest score reported during the assessment period.
Measured: First 60 minutes after extubation
Requirement and level of oxygen therapy
Requirement for oxygen therapy and the highest level of escalation within the first 60 minutes after extubation, including nasal cannula, simple face mask, reservoir mask, or more advanced oxygen delivery devices as clinically indicated.
Measured: First 60 minutes after extubation
Incidence of postoperative nausea and vomiting
Incidence of postoperative nausea and vomiting occurring within the first 60 minutes after extubation. Nausea and vomiting are recorded as present or absent during the assessment period.
Measured: First 60 minutes after extubation
Patient satisfaction
Patient satisfaction with anesthetic care at 24 hours after surgery, assessed using a 0-10 numerical rating scale (NRS), where 0 indicates complete dissatisfaction and 10 indicates complete satisfaction. The recorded value represents the patient's reported score at the 24-hour assessment.
Measured: At 24 hours after surgery (± 2 hours)
Incidence of extubation-related adverse events
Incidence of extubation-related adverse events during the post-anesthesia care unit (PACU) stay, including bronchospasm, laryngospasm, reintubation, and post-obstructive pulmonary edema. Events are recorded as present or absent throughout the PACU monitoring period. The PACU stay typically lasts 2-3 hours depending on discharge criteria.
Measured: From arrival in the PACU until discharge from the PACU, assessed up to 6 hours after PACU arrival.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
