Working with micropipettes,single or multi channel, for a long time can cause health hazard. As known in medical terms it is “Carpal Tunnel Syndrome”. Main symptom is pain in wrist and hand.
Researchers performing many dilutions using micropipettes (e.g. Dilutions for ELISA, micro arrays or bioassays etc.) are susceptible to this. Prolong handling of computer mouse also ends with same syndrome.
Carpal tunnel is a narrow tunnel formed by the bones and other tissues of wrist. The chief nerve in this area is median nerve. Repeated movements of fingers and wrist while pipetting make other tissues in the carpal tunnel, such as ligaments and tendons, get swollen or inflamed and they press against this median nerve. It gives rise to pain. Sometimes loss of sense occurs. Hand feels numb. In more advanced stage the pain may go down to spinal cord affecting neck, shoulders, back and even legs.
Precaution to avoid the disorder– Body and hands’ proper position during work, take breaks in between and exercise.
Alternate options – use electronic pipettes or high throughput robots.
