3. Implementing intraoperative microbreaks and stretching
The American College of Surgeons (ACS) recommends that surgeons avoid prolonged static postures during procedures.28 One strategy for preventing sustained positioning is to incorporate breaks with associated stretching routinely during surgery.28
Microbreaks. In a landmark study by Park and colleagues in 2017, 120-second long targeted stretching microbreaks (TSMBs) were completed every 20 to 40 minutes during a surgery, and results demonstrated improved postoperative surgeon pain scores without an associated increase in the length of the case.41 These surgeons reported improved pain in the neck, bilateral shoulders, bilateral hands, and lower back. Eighty-eight percent of surgeons reported either improvement or “no change” in their mental focus, and 100% reported improvement or “no change” in their physical performance after TSMBs were implemented.42 Of surveyed surgeons, 87% wanted TSMBs incorporated routinely.41,42
Stretches. Multiple resources, such as the ACS and the Mayo Clinic, for intraoperative stretches are available. The ACS recommends performing neck and shoulder stretches during intraoperative microbreaks, including a range-of-movement neck exercise, deep cervical flexor training, and standing scapular retraction.28 The ACS also demonstrates lumbrical stretches for the fingers and passive wrist extension exercises to be used intraoperatively (or between cases) (FIGURE 1).28 The Mayo Clinic Hallbeck Human Factors Engineering Laboratories has a publicly available “OR Stretch Instructional Video” in which the surgeon is guided through several different short stretches, including shoulder shrugging and side bends, that can be used during surgery.43
Both the ACS and the Mayo Clinic provide examples of pertinent stretch exercises for use when not in the sterile environment, between cases or after cases are complete. The ACS recommends several neck and shoulder stretches for the trapezius, levator scapulae, and pectoralis and recommends the use of a foam roller to improve thoracic mobility (FIGURE 2).28 As above, the Mayo Clinic Hallbeck Human Factors Engineering Laboratories has a publicly available “OR-Stretch Between Surgery Stretches Video” in which the surgeon is guided through several short stretches that are done in a seated position, including stretches for the hamstring, lower back, and arms (FIGURE 3).43
Many of the above-mentioned stretches were designed for use in the context of open, laparoscopic, or robotic surgery. For the vaginal surgeon, the intraoperative ergonomic stressors differ from those of other routes of surgery, and thus stretches tailored to the positioning during vaginal surgery are necessary. In a video recently published by the Society of Gynecologic Surgeons, several stretches are reviewed that target high-risk positions often held by the surgeon or assistant when operating vaginally.44 These stretches include cervical retraction, thoracic extension, external arm rotation, cervical side bending, and lumbar extension (FIGURE 4).44 The recommendation is to complete these exercises 2 times per day, with 8 to 10 repetitions per set.44
Prioritizing ergonomic awareness and training
As caregivers, it is not uncommon for us to prioritize the needs of others before those of ourselves. However, WMSDs are prevalent, and their downstream effects may cause catastrophic professional and personal losses. Cumulatively, the global impact of WMSDs is a significant issue for the health care workforce and its longevity.
To prevent WMSDs, it is imperative that surgeons are aware of the factors that contribute to injury development and the appropriate, accessible modifications for these factors. While each surgical modality confers its own ergonomic challenges, these risks can be mitigated through increased awareness of OR setup, surgeon positioning, and incorporation of microbreaks and stretching exercises during and after surgical procedures.
Formal training in surgical ergonomics is lacking across specialties, including gynecology.45 Multiple educational interventions have been proposed and studied to help fill this training gap.30,46-49When used, these interventions have been associated with increased knowledge of surgical ergonomic principles or reduction in surgeon pain scores, including trainees.50 As we become more cognizant of WMSDs, standardized resident curricula should be developed in an effort to reduce the prevalence of these potentially career-ending injuries.
In addition to education, cultivating a culture in which ergonomics is prioritized is essential. Although most surgeons report work-related pain, very few report their injuries to occupational health. For example, while 29% of gynecologic oncologists reported seeking treatment for a WMSD, only 1% had reported their injury to their employer.5 In a study of ACS members, only 19% of injuries were reported, 30% of surgeons stated that they did not know how to report an injury, and 21% felt that the resources for surgeons during and after an injury were inadequate.6
As we prioritize the health and safety of our patients, we also need to promote ergonomic awareness in the OR, respect the need for accommodations, encourage injury reporting, support surgeons who need to take time away for medical treatment, and partner with industry to develop new instruments and technology with effective ergonomic features. ●
