Intubation in Supine Versus Lateral Position Using Different Tools of Laryngoscopy in Patients With Neck Masses

March 29, 2026 updated by: Alaa Mohamed Mohamed Attia, Aswan University

Endotracheal Intubation in Supine Versus Lateral Position Using Different Tools of Laryngoscopy in Patients With Neck Masses: A Comparative Study

This study is aimed to compare different tools of endotracheal intubation in supine versus lateral position in patients with neck masses.

Primary outcome: is time taken for intubation.

Secondary outcomes:

  • The success rate of first intubation trial.
  • Hypoxia, Spo2 < 90%.
  • Airway trauma like; dental and lip injury.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

  • Before randomization, we will record morphometric characteristics including the Mallampati score, mouth opening (inter-incisor distance in centimeters), and thyromental distance (with the head extended in upright position, in centimeters).
  • Prediction of difficult intubation using Wilson score

Description

Inclusion Criteria:

  • Patients with different neck masses undergoing thyroid and non-thyroid surgeries.
  • Both genders.
  • Patients > 18 years old.
  • with the American Society of Anesthesiologists (ASA) physical status I or II.

Exclusion Criteria:

  • Patients with spine deformities limiting lying supine or lateral.
  • age under 18 years.
  • with the American Society of Anesthesiologists (ASA) physical status III or IV

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Group-SM
patients will be intubated in supine position in whom the Macintosh laryngoscope will be used
Group-SV
patients will be intubated in supine position in whom the video-assisted laryngoscopy will be used
Group-LM
patients will be intubated in lateral position in whom the Macintosh laryngoscope will be used
Group-LV
patients will be intubated in lateral position in whom the video-assisted laryngoscopy will be used

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
time taken for intubation
Time Frame: periprocedural (less than 60 seconds)
the time for the laryngoscope to pass level of incisors till confirmation of tracheal intubation by capnography
periprocedural (less than 60 seconds)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
- The success rate of first intubation trial.
Time Frame: through study completion (about 8 months)
Number of intubation attempts (an intubation attempt will be deemed failed if desaturation occurs Spo2 <90 % or intubation failed in <60 seconds). Intubations will be deemed failures after 3 intubation attempts.
through study completion (about 8 months)

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 15, 2025

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
November 15, 2025

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
