Pass the needle tip through the vessel wall with a slight upward push against the tip of the forceps, allowing the needle to exit the wall at a perpendicular. Place the tip of the left hand forceps against the vessel wall just beyond this spot. To make the exit bite through the other vessel, bring the needle tip to the point where you want it to come out. Adjust the clamps so that there is about one vessel’s width between the two vessel ends. Remove any surrounding adventitia from the vessel ends with the scissors. With micro scissors, cut the vessel midway between the clamps. Cut out a small square piece of the nitrile glove to use as a background for contrast. Place the double clamp over the vessel using the Rizutti clamp appliers. There may be a nerve attached to the vessel that should be stripped off.

Use the curved dissecting scissors to free tissue off the vessel. Vessel Preparation:Ĭlean the vessel further under the microscope. Inspect the instruments to make sure they are in good working order. The room in which you will be practicing will already be supplied with microsurgery instruments and sutures. Arrange your body position and your microscope appropriately as described in " Getting Comfortable." Turn the light source on and put it on the highest setting. Place the chicken foot under the microscope. Once the blood vessel is dissected, place the foot onto the middle of the cutting board and secure it by placing 2 or 3 rubber bands around the foot and over the cutting board. Be sure to choose the largest feet for your exercise, since they will have bigger vessels. Once defrosted, place the chicken foot on the cutting board. To defrost, place in hot tap water for 20 minutes. They will be in ziplock bags, with 3-4 feet per bag. Early mornings, late afternoons/evenings, and weekends tend to be the most available times.) Dissecting the Vessel:Ĭhicken feet will be kept in the freezer in the Plastic Surgery Office. Be sure to sign in prior to using the microscope. It is located on the second floor of the Hagey Lab, 257 Campus Drive, room GK209. The surgical microscope is located within the laboratory of Dr. (For Stanford trainees: Supplies will be housed in the Plastic Surgery Offices. Additionally, our study provides evidence supporting an increased role of summary feedback to effectively train novices in technical skills.Use the chicken foot as a practice model once you've gotten the basics of suturing down with one of the lower fidelity models. Thoughtfully incorporated into technical curricula, CBVI can make efficient use of faculty time and serve as a useful pedagogic adjunct for basic skills training. Our study showed that CBVI can be as effective as summary expert feedback in the instruction of basic technical skills to medical students. The CBVI, concurrent feedback and summary feedback methods were equally effective initially for the instruction of this basic technical skill to naive medical students and displayed better performance than control (control, 12.71 CBVI, 16.39 concurrent, 16.97 summary, 16.09 P. There were no differences in GRS between groups at pre-test. Data were analyzed using repeated-measures ANOVA. Performance was evaluated using both expert-based (Global Rating Scores) and computer-based assessment (Hand Motion Analysis). The effectiveness of training was assessed both at an immediate post-test and 1 month later at a retention test. All participants underwent 19 trials of practice, over 1 hour, in their assigned training condition. The students were subsequently assigned randomly to 4 practice conditions: no additional intervention (control), self study with CBVI, expert feedback during practice trials (concurrent feedback), and expert feedback after practice trials (summary feedback). Using bench models, participants were pre-tested on a suturing and instrument knot-tying skill after viewing an instructional video. We carried out a prospective, randomized, 4-arm study including control arm, blinding of examiners to determine effectiveness of computer-based video instruction (CBVI) and different types of expert feedback (concurrent and summary) on learning of a basic technical skill.
