Recent Guideline Updates

Neurology. 2011 April
http://www.neurology.org/content/early/2011/04/08/WNL.0b013e3182166ebe  Clinical Practice Recommendations for 2011. Revisions were made to the guidelines stating that pregabalin is now the preferred recommen- dation for diabetic neuropathy, considering it has better quality of studies than other diabetic peripheral neuropathy medications. Drug Information Question
Are there any reports of carpel tunnel syndrome related to pharmacy job
roles, specifically technicians? Also, are there any studies regarding the inci-
dence or ways to prevent carpel tunnel?

A search was conducted through PubMed, the American Academy of Orthopaedic Surgeons, specifically the carpal tunnel guidelines, and the US Deparment of Labor Bureau of Labor Statistics. Carpal tunnel syndrome is classified as compression neuropathy of the median nerve at the wrist. This causes increased pressure and results in a decreased function of the nerve. Carpal tunnel may be caused by various dis- eases, conditions or events. This disorder may affect various patients unrelated to age, gender, ethnicity, or occupation; however it is associated with systemic disease, local mechanical and other disease factors.1 Based on our findings, there was no information directly linking pharmacy related job roles with carpel tunnel syndrome. However, the nature of pharmacy related jobs may create a risk for the development of upper extremity disorders, due to repetitive movements, unnatural posi- tions of the hands and wrists and the strong gripping of pharmacy products.2 An important key consideration is that multiple factors, including: manual labor (especially repetitive tasks), individual co-morbidities and other personal factors can increase a patient’s risk of developing carpal tunnel syndrome. Manual labor examples specific to pharmacy may include opening bottles and jars, preparing batch syringes and IV bags, type/order entry, and preparing prescription vials. Personal factors and co- morbidities include diabetes, arthritis, hypothyroidism and gout.2

Carpal tunnel may be present if anyone is experiencing pressure or pain in their wrists. Prevention strategies include having correct posture, sufficient rest breaks and stretching, and utilizing properly fitted work spaces. The recommended posture is keeping the shoulders relaxed, no twisting or bending the head to the side, elbows and wrists kept in a straight position, and feet should remain on the stool rung or the floor to alleviate any lower back stress. Work stations should be fitted to the physical statue of the individual worker, to help avoid any unnatural positions or straining and to rotate jobs among workers. Frequent breaks are recommended, as well as the use of cold packs and nonsteroidal anti- inflammatory medications to reduce swelling.2 Below is a list of suggestions to help avoid carpel tunnel syndrome: 3 Chair, armrests causing problems ensure that the chair is adjustable and has armrests that can be removed or added, depending on the individual and the procedure being performed gloves that are too tight can cause unnecessary pressure in the wrist area. Wear the correct glove size to avoid cumulative injury to the wrist and hand maintain wrists in a neutral position; ensure good ergonomic setup at all stations break up tasks into more manageable pieces, take regular breaks, and reduce the speed and try to reduce time spent preparing syringes; rotate preparation among a number of staff; use a peristaltic pump to help with procedures consider an ergonomic assessment to optimize workflow do mental checks to self-monitor posture maintain a healthy, active lifestyle outside work hours 1.Clinical Practice Guideline of The Diagnosis of Carpal Tunnel Syndrome [Internet].
