Descrição detalhada
After approval from the institutional Ethical Committee, 60 patients were studied. A randomised prospective study was planned to compare size 1 Airtraq (Prodol Meditec S.A., Vizcaya, Spain) with Miller blade of same size.
The children included in the study were 2-10 years of age, American Society of Anesthesiologists (ASA) physical status I-II and posted for elective surgeries requiring tracheal intubation. The following were excluded from the study: (i) patients with upper respiratory tract symptoms, (ii) those at risk of gastroesophageal regurgitation and (iii) those with airway-related conditions such a trismus, limited mouth opening, trauma or mass. Sixty patients were equally randomized to one of the two groups (Airtraq and Miller) of 30 each for airway management using a computer-generated randomization program.
Written informed consent was taken from the parents prior to intervention and a standardized protocol for anesthesia was maintained for all cases. All the children were kept nil per mouth as per standard guidelines. Intubation attempts were taken using Airtraq or Miller on a random basis.

Intervenção / Tratamento |
|---|---|
|
Comparador Ativo: Intubation with Miller's blade
After induction and muscle paralysis, Miller's blade was introduced in the patient's mouth.
After visualization of vocal cord, patient was intubated with appropriate sized tracheal tube.
|
Intubation is insertion of a hollow tube inside the trachea.
It is done after laryngoscopy with Miller's blade.
|
|
Experimental: Intubation with Airtraq laryngoscope
After induction and muscle paralysis, Airtraq laryngoscope's blade was introduced in the patient's mouth.
After visualization of vocal cord as a reflected image in the viewfinder of the device, patient was intubated with appropriate sized tracheal tube.
|
Intubation is insertion of a hollow tube inside the trachea.
It is done after laryngoscopy with Airtraq.

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Time to Intubation
Prazo: 5 minutes
|
It is defined as the time from placement of Airtraq or Miller laryngoscope into the mouth till appearance of the capnograph waveform
|
5 minutes
|
Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Number of Intubation in First Attempts;
Prazo: 5 minutes
|
A single insertion of the Airtraq or a single insertion of the Miller laryngoscope blade into the mouth with passing the endotracheal tube beyond the glottis was considered as an attempt.
|
5 minutes
|
|
Ease of Intubation.
Prazo: 5 minutes
|
The intubating anaesthesiologist graded the ease of intubation for both techniques on a visual analogue scale from 1 to 10, 10 being most difficult or failed intubation and 1 being very easy intubation.
|
5 minutes
|
|
Percentage of Glottic Opening Scoring.
Prazo: 5 minutes
|
The Percentage of glottic opening score represents the percentage of glottic opening seen, defined by the linear span from the anterior commissure to the interarytenoid notch
|
5 minutes
|
|
Overall Intubation Success Rate.
Prazo: 5 minutes
|
It is the number of participants who were successfully intubated after first, second or third attempts.
Success of intubation is defined as placement of endotracheal tube inside the trachea, confirmed by bilateral chest auscultation and square wave capnograph tracing.
|
5 minutes
|
|
Number of Esophageal Intubation.
Prazo: 5 minutes
|
Insertion of tracheal tube inside the esophagus
|
5 minutes
|
|
Number of Participants With Airway Trauma
Prazo: 5 minutes
|
Airway trauma was defined as blood detected on the blades of laryngoscopes, blood on endotracheal tube after extubation or tongue-lip-dental trauma.
