AUDIOVISUAL RESOURCES ON THE TEACHING PROCESS IN SURGICAL TECHNIQUE

Area of Science:

• Medical Education
• Surgical Training
• Pedagogical Strategies

Background:

• In vivo surgical training is increasingly challenging.
• Audiovisual resources can optimize educational resources and minimize reliance on verbal instruction.
• Digital video offers a potential solution for repetitive viewing of surgical procedures.

Purpose of the Study:

• To assess the efficacy of digital video as a teaching strategy for surgical techniques in medical education.
• To compare the impact of traditional teaching versus video-enhanced teaching on surgical skill acquisition.

Main Methods:

• A cross-sectional study involving 48 third-year medical students in a surgical technique course.
• Students were divided into two groups: one receiving conventional teaching, the other receiving conventional teaching plus video demonstrations.
• Phlebotomy was performed in a laboratory setting, with subsequent self-administered questionnaires to evaluate the teaching methods.

Main Results:

• Students exposed to video demonstrations completed the procedure faster, asked fewer questions, and required less faculty assistance.
• 95.83% of students who watched the video felt confident repeating the procedure independently.
• Students relying solely on conventional methods reported lower capacity for technique assimilation and greater difficulty performing the procedure.

Conclusions:

• Combining traditional teaching with video visualization significantly improved understanding and confidence in surgical techniques.
• Video-assisted learning motivated students, increased interest, and facilitated comprehension and memorization of procedural steps.
• Digital video integration positively impacted student performance in surgical technique acquisition.
