Purpose:
Robotic-assisted surgery (RAS) is becoming increasingly popular with one of its praised benefits being improved ergonomics. While other types of interventions like open or laparoscopic surgery have been assessed regarding the noise exposure and evaluations regarding the ergonomics are based on these findings, there are no studies analyzing the changed environment of tele-operated RAS.
Methods:
Twelve robotic interventions with an average length of 3.5 h, including (hemi-)colectomies, anterior rectum resections and sigmoidectomies were assessed using a sound level meter. Recordings were monitored by a medical expert, manually annotating individual phases of the intervention from the patient's entry till the exit of the operating room. Measured sound data were afterward mapped to one out of six corresponding surgical phases.
Results:
The data showed an average noise level of 60.5(±3.35) dB(A) and a L(A)eq of 63.49 dB(A) with the robotic phase being significantly, but only 0.15 dB(A) louder than the non-robotic surgical part (60.4(±3.14) dB(A)). Overall the peri-surgical phase was louder than the surgery itself with the post-surgical phase being the loudest of all phases with a level of 61.2 (±4.82) dB(A).
Conclusions:
Regarding sound levels tele-operated RAS seems comparable with open and laparoscopic surgery, despite the robotic phase being to a small extent louder within this evaluation. Nevertheless sound levels appear high and further reduction should be considered in order to improve ergonomics and patient safety.
