ABSTRACT
BACKGROUND AND AIMS: Surgical interventions involving urinary catheterisation often lead to catheter-related bladder discomfort (CRBD). With a very high incidence rate of 47%-90%, CRBD often leads to a distressing and painful recovery after surgery. Although many opioids have been used for the treatment of CRBD, the search for the best is still going on. This study investigated the efficacy and tolerability of oral tapentadol and tramadol on postoperative CRBD. METHODS: This was a prospective, randomised double-blind study. 100 patients, undergoing transurethral resection of the prostate were randomly assigned into two groups to receive tramadol 100 mg (Group A) or tapentadol 50 mg (Group B) orally 1 h before surgery. CRBD was evaluated on a 4-point severity scale in the post-operative area at 0, 0.5, 1, 2, 3, 4, 5 and 6 h. Pain and adverse effects were assessed postoperatively. Serum cortisol levels before and after the procedure were noted. Statistical analysis was done with the analysis of variance, t test. RESULTS: Postoperative CRBD, 2 h after surgery was significantly reduced in group B than group A (P = 0.012). Cortisol levels, postoperatively were significantly lower in Group B (113 ± 65.45) (P = 0.001) than group A (162.64 ± 118.84 ng/dL). Dry mouth was seen in four, nausea in eight and sedation in six patients in group A while none in group B. 14 patients in Group A and one patient in Group B needed intravenous paracetamol (P = 0.000). CONCLUSIONS: Premedication with tapentadol was more effective in reducing CRBD and pain postoperatively. The surgical stress response and side effects were significantly reduced with tapentadol.
