Brief Summary

Diaphragm ultrasound non-invasively explores the diaphragm function and it can be useful in several clinical situations. Diaphragm ultrasound is able to evaluate the cranio-caudal displacement of the diaphragm and its thickening fraction at the end of inspiration, in relation to the end-expiratory value. While several studies have been conducted in the evaluation of educational programmes for echocardiography, to date data lack regarding this aspect in diaphragm ultrasonographic assessment. Based on the experience gained in some specialization schools in Anaesthesia and Intensive Care, the investigators hypothesize that the participation in a two-hour course, including a theoretical part and a practical training, allows to acquire the appropriate theoretical and practical skills necessary to correctly perform the measurement of the diaphragm excursion and thickening fraction, compared to the theoretical lesson only, followed by a brief explanation by an expert tutor, on the practical use of the ultrasound. The investigators hypothesized that the association of the theoretical part and of the practical training is able to obtain:

  1. 1.Passing the theoretical test with at least 70% of the correct answers;
  2. 2.The correct identification of the areas where the probe is affixed;
  3. 3.The appropriate measure of Diaphragmatic thickening and displacement.

Outcome Measures

Primary Outcomes (2)

  • Ultrasonographic skills - Thickening Fraction

    Measurement of thickening fraction. If measurements will deviate from those recorded by the expert within the 20% of the value, the result will be considered positive

    Soon after the video-tutorial (within 30 minutes), when participants perform diaphragm ultrasound

  • Ultrasonographic skills - Diaphragm Displacement

    Measurement of Diaphragm Displacement. If students' measurements will deviate from those recorded by the expert within the +/- 2 mm, the result will be considered positive.

    Soon after the video-tutorial (within 30 minutes), when participants perform diaphragm ultrasound

Study Arms (2)

"Tutor" group

EXPERIMENTAL

After a theoretical part through the administration of a video-tutorial, a 10-point questionnaire will be administered to evaluate the level of learning for each participant. Every single participant will pass the test if he/she correctly answer to \>70% of the questions. Those passing the test, will be randomized to two groups. The interventional group will access the practical training, during which each participant will be followed by a tutor who will interactively explain, using a healthy volunteer, how to perform the ultrasound scan of the diaphragm. The ultrasound will be performed on a healthy volunteer first by the tutor and then by the participants. During the exercise, each individual learner will be supervised by the tutor himself.

Other: Tutor

"No tutor" group

NO INTERVENTION

This control group will directly perform the ultrasound examination of the diaphragm. The expert tutor will only show the learners how to use the various functions of the ultrasound, the linear and convex probes both in two-dimensional and in M-mode.

Interventions

TutorOTHER

The participants will access the practical training, during which each participant will be followed by a tutor who will interactively explain, using a healthy volunteer, how to perform the ultrasound scan of the diaphragm. The ultrasound will be performed on a healthy volunteer first by the tutor and then by the participants. During the exercise, each individual learner will be supervised by the tutor himself.
