Intracutaneous sterile water injection for pain relief during extracorporeal shock wave lithotripsy: comparison with diclofenac sodium.
Various analgesic applications can be used during extracorporeal shock wave lithotripsy (SWL) for pain relief and maximal success rate. Intracutaneous sterile water injection (ISWI) has been shown to be effective in several types of pain, but a gap exists about its use during SWL. In this paper, we aimed to evaluate the effect of ISWI during SWL and compare that with diclofenac sodium injection used commonly to provide ideal patient contentment. ⋯ The characteristics of the patients and shockwave therapy did not differ significantly between the two groups. Although the mean VAS scores prior to SWL and at every voltage increment during the procedure did not differ, more patients in the diclofenac sodium injection group required rescue analgesia with significantly greater side effects. ISWI is found to be as effective as the diclofenac sodium injection for pain management during SWL with lower adverse event rates.
