# Comparison of Two Blades of Videolaryngoscope in Simulated Difficult Airway in Children

**Official Title:** Comparison of Two Blades of Videolaryngoscope in Simulated Difficult Airway in Children, a Randomized Controlled Trial

**NCT ID:** [NCT03719638](https://clinicaltrials.gov/study/NCT03719638)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 47
- **Lead Sponsor:** Kocaeli University
- **Conditions:** Intubation;Difficult
- **Start Date:** 2018-11-15
- **Completion Date:** 2019-03-15
- **CT.gov Last Update:** 2020-11-10

## Brief Summary

Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The D-blade of videolaryngoscope is preferred in difficult intubation with a more curved blade then the Macintosh videolaryngoscope blade, which may be more useful in difficult intubation. The aim of the study is to compare the D-blade of videolaryngoscope with Macintosh videolaryngoscope blade.

## Eligibility

- **Minimum age:** 1 Year
- **Maximum age:** 5 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* ASA I-II patients
* Undergoing elective surgeries
* Age between 1-5 years

Exclusion Criteria:

* Anticipated difficult intubation
* Pulmonery diseases
* \>III ASA scores
```

## Arms

- **D-blade group** (ACTIVE_COMPARATOR) — Intubation will be done using D-blade of videolaryngoscope in a simulated difficult airway Difficult airway will be simulated with collar.
- **Macintosh group** (ACTIVE_COMPARATOR) — Intubation will be done using Macintosh videolaryngoscope in a simulated difficult airway Difficult airway will be simulated with collar.

## Interventions

- **D-blade of videolaryngoscope** (DEVICE) — intubation will be done using d-blade of videolaryngoscope
- **simulated difficult airway** (OTHER) — extension of head will be limited by using collar.
- **Macintosh videolaryngoscope** (DEVICE) — intubation will be done using macintosh videolaryngoscope

## Primary Outcomes

- **intubation time** _(time frame: time between handling videolaryngoscope and inserting endotracheal tube)_ — Time of endotracheal intubation will be recorded.

## Secondary Outcomes

- **Cormack and Lehane score** _(time frame: During the intubation)_
