Abstract
BackgroundThe peripheral venous catheter is the most frequently used medical device in hospital care to administer intravenous treatment or to take blood samples by introducing a catheter into a vein. The aim of this study was to examine the effect of motor imagery associated with actual training on the learning of peripheral venous catheter insertion into a simulated venous system.MethodThis was a prospective monocentre study in 3rd year medical students. Forty medical students were assigned to the experimental group (n = 20) performing both real practice and motor imagery of peripheral venous catheter insertion or to the control group (n = 20) trained through real practice only. We also recruited a reference group of 20 professional nurses defining the benchmark for a target performance.ResultsThe experimental group learned the peripheral venous catheter insertion faster than the control group in the beginning of learning phase (p < 0.001), reaching the expected level after 4 sessions (p = .87) whereas the control group needed 5 sessions to reach the same level (p = .88). Both groups were at the same level at the end of the scheduled training.ConclusionsTherefore, motor imagery improved professional motor skills learning, and limited the time needed to reach the expected level. Motor imagery may strengthen technical medical skill learning.
Highlights
The peripheral venous catheter is the most frequently used medical device in hospital care to administer intravenous treatment or to take blood samples by introducing a catheter into a vein
The students watched an instructional video on peripheral venous catheter (PVC) insertion, performed the technique twice under the supervision of 2 trainers that were naive in relation to the objectives of the experiment
At the end of the first session, we evaluated the students Motor imagery (MI) ability with the Motor Imagery Questionnaire (MIQ-3) [31], and a mental chronometry test (Fig. 2)
Summary
The peripheral venous catheter is the most frequently used medical device in hospital care to administer intravenous treatment or to take blood samples by introducing a catheter into a vein. The aim of this study was to examine the effect of motor imagery associated with actual training on the learning of peripheral venous catheter insertion into a simulated venous system. The insertion of peripheral venous catheter (PVC) is one of the most common medical procedures used by clinicians. It involves inserting a catheter into a vein to administer intravenous therapy or to allow blood collection. Experienced surgeons view MI as the most effective procedure for complex and stressful situations preparation, probably because the cognitive demands are close to those mobilized during MI, e.g. the ability to self-represent the spatial environment in which surgery will take place [9, 13, 26, 28]. Associating MI to real practice may favour the learning in health professions [7]
