Evaluation of a novel C‐Arm draping technique to minimize surgical field contamination and surgery time

Abstract

Background The purpose of this study is to compare the sterility of three C‐Arm draping techniques: the clip‐drape, sterile pouch, and a novel drape tower method. We hypothesize that our novel technique will minimize floor contamination from reaching the surgical field while allowing the C‐Arm machine to rotate between lateral and anterior–posterior positions more quickly. Methods Five trials consisting of rotating the C‐Arm and simulating surgeon movement were run using each technique. Ultraviolet light illuminating melamine powder was used to represent floor contamination. Measurements of melamine powder encroachment on the drapes were taken using the top of the C‐Arm in lateral position as the reference point. The time needed to assemble, deploy, and retract the C‐Arm was measured for each technique. The gown, gloves, and mayo stand were also examined after each trial for contamination. Results Compared to the clip drape, the drape tower prevented contamination from reaching the C‐Arm by an additional 30.5 cm (95% confidence interval (CI): 17.0–43.9, P < 0.001). The drape tower had faster deployment and retraction times than both the clip drape (P < 0.001 and P < 0.001, respectively) and sterile pouch (P = 0.011 and P < 0.001, respectively). The clip drape and sterile pouch exhibited glove contamination in two (40%) simulations, while the drape tower showed no instances of contamination (P = 0.255). Conclusions The novel drape tower technique limits the encroachment of floor contamination onto sterile drapes. It should be considered as an alternative draping method for lower extremity surgery.

Time to entry point and distal locking of intramedullary nails: a methodological phantom study comparing biplanar and uniplanar surgical imaging

“…The surgeon-operated mini C-arm showed contamination of the drapes in 70% of the cases [ 15 ]. Newer draping techniques of the C-arm compared to older seem to decrease contamination [ 16 , 17 ]. A future comparative study between uniplanar and biplanar imaging regarding surgical field contamination might be warranted.…”
