Efficiency of intracavitary levobupivacaine infusion for pain management during cystoscopic procedures: A randomised study.

AIM

This study evaluated the effect of intracavitary levobupivacaine infusion diluted with locally applied isotonic solution for pain control in cystoscopy.

METHODS

Included in this study are 100 patients who had previously undergone transurethral tumour resection for bladder tumour and were followed up by cystoscopy. The patients were randomised into five groups (n = 20). In the first, second, third, and fourth groups, 4, 6, 8, and 10 mL of levobupivacaine HCl (5.0 mg/mL) were mixed with 26, 24, 22, and 20 mL of isotonic solution, respectively. Hence, the total mixture was 30 mL for each group. The fifth group was the control group. In this group, the standard method commonly used in most clinics was utilised. That is, a gel containing Cathejell-2% lidocaine (25 mg lidocaine) was applied for local analgesia. Cystoscopic interventions were performed with a 17.5 Fr rigid cystoscope and 0°, 30°, and 70° lens. During cystoscopy and 30 min later, the pain status of patients was assessed using the Visual Analogue Scale (VAS) and patient satisfaction was questioned.

RESULTS

The mean VAS score during and after the cystoscopy procedure was significantly lower in the levobupivacaine groups compared with the lidocaine group. In addition, patient satisfaction in the levobupivacaine groups was significantly higher than in the lidocaine group. No drug-related side-effects were observed in all groups.

CONCLUSION

Thus, levobupivacaine is a more effective drug than lidocaine alone to control pain during cystoscopy. The use of levobupivacaine is recommended to prevent possible complications of general anaesthesia by eliminating the need for the aforementioned as well as its cost-saving advantage.
