Trial Outcomes & Findings for Performance of Baccalaureate Nursing Students in Insertion of Laryngeal Mask: a Trial in Mannequins (NCT NCT01659268)

NCT ID: NCT01659268

Last Updated: 2014-06-02

Results Overview

Score obtained in pre and post-test written, time to obtain the first effective ventilation (chest expansion through adequate ventilation on the mannequin), number of attempts to insert the LMA in the simulation scenario (OSCE). Pre-test: 20 questions with score of 0.5 points each - minimum score=0 points and maximum score=10 points. Score 5-7 points was considered satisfactory; scores between 7-8 points was considered good performance; above 8 points excellent. Post-test: 20 questions with score of 0.5 points each - minimum score=0 points and maximum score=10 points. Score 5-7 points was considered satisfactory; scores between 7-8 points was considered good performance; above 8 points excellent. OSCE: instrument with total of 10 skills - each skill was subdivided in 4-5 activities (0.2-0.25 points each) - poor performance was score \< 5.0; satisfactory performance 5.0-7.0; good 7.0-8.5 and excellent above 8.5 points.

Participant Flow

The strategy of data collect were Workshop "Airway management in emergencies: use of laryngeal mask" which dates of realization 21/11/2012 to 24/11/2012. The disclosure of event were e-mail, site of the institution and posters. Students entries were made through electronic.

The activities were described for the students in the arrive to the workshop.

Measure
Simulation Class
The students will be submitted a simulation scenario in laboratory with low-fidelity mannequin for 60 minutes, in subgroups of 4-5 students. The simulated condition is a patient in respiratory failure which need of emergency interventions. The approach concepts of anatomic, physiology and clinical interventions using LMA will be discussed during simulation.
Control
The students randomized to CG will be submitted to exhibition-dialogued class with duration of 60 minutes; after this, will go to the and practical activity in skill lab using the low-fidelity mannequin. Each subgroup will be composed of 4-5 students for the practice activity which will last 35 minutes.
