Abstract
Background: Most patients experience some degree of pain during extracorporeal shock waves lithotripsy (ESWL). Aim: The aim of this study was to evaluate the effect of target-controlled infusion (TCI) of remifentanil or sufentanil and patient-controlled analgesia (PCA) with sufentanil or morphine for pain relief during ESWL. Materials and Methods: In a double blind, randomized clinical trial, a total of 60 patients who were scheduled for elective ESWL, randomly assigned into four groups (A, B, C and D). Patients in group A and B received remifentanil and sufentanil with TCI, respectively. Also, patients in group C and D received sufentanil and morphine with PCA, respectively. All patients in four groups were assessed about the intensity of their pain with Visual Analogue Scale (VAS) in three phases; the discharge of the waves (phase A), during breaking the stones (phase B) and the end of the procedure (phase C). Results: Patients in morphine PCA group experienced highest pain intensity in all stages, but patients in remifentanil TCI group experienced lowest pain intensity during lithotripsy. Remifentanil/TCI group experienced the lowest pain in B and C phases and the sufentanil/TCI group had the lowest pain only in the phase A. There was no significant difference in the occurrence of complications in all four groups. Conclusion: The current study demonstrates that efficacy of TCI pump in the reduction of pain during ESWL is superior to the PCA pump. Among the drugs that used in this study, remifentanil has more effective in pain management in the all phases during ESWL. We believe that using remifentanil/TCI should strongly be considered to clinicians in ESWL units.
