Obesity Clinical Trial
Official title:
A Comparison of Tracheal Intubation Using the Totaltrack vs the Macintosh Laryngoscope
Airway management in obese patients has to consider that mask ventilation (DMV) risk is
increased and difficult tracheal intubation (DTI) risk may be increased too.
In obese patients, is essential to prevent early arterial oxygen desaturation related to a
reduced functional residual capacity (FRC), atelectasis formation during anesthetic
induction and after tracheal intubation, because oxygenation maintenance is the cornerstone
of the airway management of the obese patient.
Endotracheal intubation is usually required to allow unrestricted surgical approach. The
Macintosh laryngoscope is the standard method. However, sometimes this technique is
ineffective and poorly tolerated by the obese patient.
The Totaltrack™ (MedComflow S.A., Barcelona, Spain) is a hybrid device, between a
supraglottic airway and a videolaryngoscope with an anatomically shaped blade. It allows
fibreoptic visualization of the larynx for tracheal intubation and was developed to aid both
ventilation and tracheal intubation, at the time of anticipated and unanticipated difficult
airway management.
However, despite its use in clinical practice, there are no comparative studies regarding
direct laryngoscopy in obese patients.
