Force application of laparoscopic surgeons under the impact of heavy personal protective equipment during COVID-19 pandemic.

ABSTRACT

Objective: Surgeons are required to wear heavy personal protective equipment while delivering care to patients during the COVID-19 pandemic. We examined the impact of wearing double gloves on surgeons' performance in laparoscopic surgery. Methods: Eleven surgeons-in-training at the Surgical Simulation Research Lab of the University of Alberta were recruited to perform laparoscopic cutting tasks in simulation while wearing none, one pair, and two pairs of surgical gloves. Forces applied to laparoscopic instruments were measured. Results: Wearing gloves prolonged task times (one pair of gloves 301.6 ± 61.7 s; two pairs of gloves 295.8 ± 65.3 s) compared with no gloves (241.7 ± 46.9 s; p = 0.043). Wearing double gloves increased cutting errors (20.4 ± 5.1 mm2) compared with wearing one pair of gloves (16.9 ± 5.5 mm2) and no gloves (14.4 ± 4.6 mm2; p = 0.030). Wearing gloves reduced the peak force (one pair of gloves 2.4 ± 0.7 N; two pairs of gloves 2.7 ± 0.6 N; no gloves 3.4 ± 1.4 N; p = 0.049), and the total force (one pair of gloves 10.1 ± 2.8 N; two pairs of gloves 10.3 ± 2.6 N; no glove 12.6 ± 1.9 N; p = 0.048) delivered onto laparoscopic scissors compared with wearing no glove. Conclusion: The combined effects of wearing heavy gloves and using tools reduced the touching sensation, which limited the surgeons' confidence in performing surgical tasks. Increasing practice in simulation is suggested to allow surgeons to overcome difficulties brought by personal protective equipment.
