Exporting simulation technology to the philippines: A comparative study of traditional versus simulation methods for teaching intravenous cannulation

This study examines effectiveness of a donated Laerdal Virtual I.V. TM simulator when compared with traditional methods of teaching intravenous (IV) cannulation to third year medical students in the Philippines. Forty novice Filipino medical students viewed an instructional video on how to start intravenous lines and were then randomly divided into two groups of twenty. The "Traditional" group observed an IV insertion on an actual patient performed by an experienced practitioner, and then subsequently performed an IV on an actual patient which was videotaped. The "Simulation" group practiced the Virtual I.V. TM simulator until they successfully completed level three using the "doctor" setting. These students then performed an IV on an actual patient which was videotaped. The videotapes for both groups were reviewed by two pre-trained (Inter-rater reliability of > 0.84) observers who were blinded to the group using a previously validated checklist for IV insertion. Students trained on the Virtual I.V. TM showed significantly greater success in successfully starting an IV on an actual patient (40% VS. 15%, p <0.05), decreased constrictive band time (p<.05), increased raw score on the check list (p<.03), and decreased overall time to start an IV (p<.05). The technology was well received but wider application in the non western world is limited by lack of in country company support and the relative expense.
