 Pre-Operative Warm-Up Betters Surgeons' Skills in the OT
A new study has said that warm-up exercises of about 15 - 20 minutes duration will significantly improve surgeons' performances. Simple surgical exercises prior to an operation betters the proficiency of surgical skills for surgeons of all experience levels.

The researchers found that a warm-up of both psychomotor and cognitive skills raises surgeons' alertness to a higher level for surgical procedures and improves performance for fatigued surgeons.

"Warm-up exercises are a 'common sense' practice in many high-stakes professions, such as professional sports or dance. This study begins to lay a scientific foundation for adopting this approach in routine surgical practice, which has become increasingly rigorous and demanding," said Kanav Kahol, Ph.D., department of biomedical informatics, Arizona State University, Tempe.

Forty-six surgeons across varying specialties and experience levels participated in the study. Subjects performed standardized exercises as a preoperative warm-up.

Afterwards, the standardized exercises were repeated in randomized order to examine proficiencies in psychomotor and cognitive skills involved in surgical procedures.

Proficiencies were measured by gesture-level proficiency, hand-movement smoothness, tool-movement smoothness, time elapsed and cognitive errors.

Additionally, the researchers investigated generalizability of preoperative warm-up by following it with a different task, electrocautery simulation. They also examined the effect of the warm-up on fatigued participants based on their performance before and after night call.

The results showed statistically significant improvements after all of the post warm-up exercises and across all experience levels.

In addition, the warm-up exercises led to a significant increase in proficiency in follow-up electrocautery simulation.

There was also a significant improvement in performance of the fatigued group compared to baseline performance, although the surgeons in this group were still not able to reach optimal potential performance.

The study is published in the February issue of the Journal of the American College of Surgeons.
