Study summary

Nasotracheal intubation is indicated in patients undergoing oral, maxillofacial, or dental procedures. During nasal intubation with the traditional Macintosh laryngoscope, use of Magill's forceps or external laryngeal manipulation is usually required to facilitate intubation. The prolonged or multiple intubation attempts and, subsequently, may be associated with complications such as oxygen desaturation or airway and dental injuries.

The C-MAC videolaryngoscope (Karl Storz, Tuttlingen, Germany) is a videolaryngoscope using a modified Macintosh blade, which may be a useful alternative both for routine and difficult airway management and for educational purposes.

In this prospective, randomized, controlled trial, the purpose is to compare C-MAC and DL in terms of intubation times, hemodynamic response and adverse events associated with nasotracheal intubation in children undergoing dental procedures.

Read the detailed description

Tracheal intubation using direct laryngoscopy is successful in the majority of patients, even when a line-of-sight view of the glottis is not possible. Although poor glottic visualization is encountered between 1% and 9% of attempts, success can generally be achieved with additional force, external laryngeal manipulation, or the use of gum elastic bougies and stylets. However, poor glottic exposure is more likely to require prolonged or multiple intubation attempts and, subsequently, may be associated with complications such as oxygen desaturation or airway and dental injuries. In recent years, videolaryngoscopy has begun to play an important role in the management of patients with an unanticipated difficult or failed laryngoscopic intubation.

What researchers measure

Primary outcomes

  1. Time to intubation

    Time to intubation was defined as the time the nasotracheal tube was inserted into nares the until endtidal CO2 was detected

    Time frame: From beginning of inserting nasotracheal tube into nares to seeing two meaningful end-tidal carbon dioxide levels up to 3 minutes

Secondary outcomes

  1. Heart Rate

    Heart Rate

    Time frame: From beginning of Anesthesia induction to 10th minutes of intubation

  2. Mean Arterial Pressure

    Mean Arterial Pressure

    Time frame: From beginning of Anesthesia induction to 10th minutes of intubation

  3. Adverse Events

    Bleeding in the mouth and nose, the Magill Forceps use, burst of intubation tube cuff, external laryngeal pressure, presence of head position change, laryngospasm, hypoxia.

    Time frame: During the first 1 hour postoperatively
