Does a Customized Intubation Facility Reduce Incidence of Difficulty (Person-OTI)

9. juni 2026 opdateret af: Hopital Foch

Does a Customized Intubation Facility Reduce Incidence of Difficulty: Randomized Multicenter Trial?

The idea of this study is to demonstrate that the position of the head at a comfort height spontaneously expressed by the patient, between Jackson's amended position or Ramp position, significantly improves the quality of the intubation gesture. This patient position can be easily achieved by placing a compressed air mattress under the patient's trunk - AirPal RAMP ™ mattress.

Thus the investigators can assume that the appropriate positioning and use of a video laryngoscope (McGrathR Mac) places the patient in the best anatomical configuration to breathe and, indirectly to facilitate control of the airways, especially for those with a risk of difficult airway management.

Detaljeret beskrivelse

  1. Position for orotracheal intubation The period preceding the administration of anesthetic agents is essential to ensure a satisfactory oxygen supply (pre-oxygenation). Then, once loss of consciousness is achieved, an interface (oral intubation probe) is put in place to allow mechanical ventilation during the procedure. This phase can be marked by a more or less expected difficulty depending on the risk factors presented by the patient. Thus an Arne score> 11 is predictive of a potential difficulty which may lead to an alternative technique being proposed. Simple techniques also exist in the patient setup to reduce the incidence of difficulties. Among them, the placement of a cushion under the head with a slight extension of the head of 20 ° (Jackson's amended position) is recommended because it allows to obtain the alignment of the posterior pharyngeal and glottic spaces. This patient position can be easily achieved by placing a compressed air mattress under the patient's trunk - AirPal RAMP ™ mattress.

    This optimization of the position according to the patient, between Jackson's amended position or Ramp position, opens up the prospect of defining an optimal position personalized to each patient. Thus, it can be assumed that the appropriate positioning places the patient in the best anatomical configuration for breathing and, indirectly, to facilitate control of the airways.

  2. Video laryngoscope The use of a video laryngoscope (McGrathR Mac) is becoming widespread in anesthesia, especially for the management of patients at risk of difficult airway management. This device by the video support at the end of the blade provides a better visualization of the glottic orifice.
  3. The hypothesis of this research The idea of this study is to demonstrate that the position of the head at a height of comfort spontaneously expressed by the patient significantly improves the quality of the intubation procedure.

Foranstaltningsbeskrivelse
Tidsramme
Assessment of the effect of patient positioning on the quality of exposure during intubation
Tidsramme: 1 day
  • the duration of the intubation;
  • the quality of visualization of the glottis;
  • failure of intubation defined by reexposure, by esophageal intubation;
  • the calculation of the Intubation Difficulty Scale (or IDS)
1 day
Determination of the most frequent complementary resettlement actions
Tidsramme: 1 day
  • the ideal position chosen by the patient (and measured) before the start of the procedure;
  • the patient's position (measured) when the intubation is successful. The intubation time will be correlated with these measurements and the angles that will be deduced from them;
  • additional techniques used at the time of intubation.
1 day
Assessment of the quality of manual ventilation before intubation (peroxygenation)
Tidsramme: 1 day
  • the use of a Guédel cannula;
  • the number of hands required for ventilation;
  • the percentage of leakage;
  • minimal SpO2;
  • maximum ETCO2.
1 day
Assessment of the frequency and severity of complications of intubation
Tidsramme: 2 days
The complications of intubation was defined by the pharyngeal pain the day after surgery, dysphonia, an irritative cough reported by the patient and atelectasis.
2 days
Assessment of patient comfort and the doctor's opinion on the technique
Tidsramme: 1 day
The doctor's opinion on the technique was defined by the regard to pre-oxygenation, peroxygenation, and intubation.
1 day
Safety assessment of the technique
Tidsramme: 1 day
Safety was evaluated by the occurrence of a fall of the head, occurrence of a fall of the patient, accidental extubation, the incidence of arterial oxygen desaturation, the lowest arterial oxygen saturation and the perception of difficulty in intubation.
