Nonsteroidal antiinflammatory drugs for postthoracotomy pain. A prospective controlled trial after lateral...

Diclofenac (Voltarol) as an adjunct to papaveretum for pain relief was examined by a prospective, randomized trial in 44 patients who had lateral thoracotomies. Patients given diclofenac, 75 mg intramuscularly twice daily, required less papaveretum in the first 3 days after operation (p less than 0.005) and had lower pain scores on a visual analog scale on all 5 postoperative days (p = 0.02 to less than 0.001); their respiratory vital capacity on the first postoperative day was also significantly higher (p less than 0.02). Diclofenac is a useful adjunct in the management of postthoracotomy pain.
