BACKGROUND: Male patients undergoing transurethral resection of bladder tumors (TURBT) are prone to suffer from catheter-related bladder discomfort (CRBD). Lidocaine administration has been widely performed to reduce postoperative pain. Here, the effect of intravenous lidocaine administration on moderate-to-severe CRBD was evaluated in male patients undergoing TURBT. METHODS: Patients were randomly allocated to receive intravenous lidocaine (1.5 mg/kg bolus dose followed by a 2 mg/kg/h continuous infusion during the intraoperative period, which was continued for 1 hour postsurgery; group L) or placebo (normal saline; group C). The primary outcome was moderate-to-severe CRBD at 0 hour postsurgery (on admission to the postanesthetic care unit), analyzed using the χ2 test. The secondary outcome was opioid requirement during the 24-hour postoperative period. None, mild, and moderate-to-severe CRBD at 1, 2, and 6 hours postsurgery, postoperative pain, patient satisfaction, side effects of lidocaine and rescue medications (tramadol and fentanyl), and surgical complications were also assessed. RESULTS: A total of 132 patients were included in the study (66 patients in each group). The incidence of moderate-to-severe CRBD at 0 hour postsurgery was significantly lower in group L than in group C (25.8% vs 66.7%, P < .001, relative risk: 0.386, 95% confidence interval: 0.248–0.602). Opioid requirements during the 24-hour postoperative period were significantly lower in group L than in group C (10.0 mg [interquartile range (IQR), 5.0–15.0 mg] vs 13.8 mg [IQR, 10.0–20.0 mg], P = .005). At 1 and 2 hours postsurgery (but not at 6 hours), the incidence of moderate-to-severe CRBD was significantly lower in group L than in group C (1 hour: 10.6% vs 27.3%, P = .026; 2 hours: 0.0% vs 15.2%, P = .003). Patient satisfaction was significantly greater in group L than in group C (5.0 [IQR, 4.8–6.0] vs 4.0 [IQR, 4.0–5.0], P < .001). No lidocaine-related side effects were reported. Rescue medication-related side effects and surgical complications did not differ significantly between the 2 groups. CONCLUSIONS: Intravenous lidocaine administration resulted in lower incidence of moderate-to-severe CRBD, lower opioid requirement, and higher patient satisfaction in male patients undergoing TURBT without evidence of significant side effects.
Urinary catheterization can cause catheter-related bladder discomfort (CRBD). Ketorolac is widely used for pain control. Therefore, we evaluated the effect of ketorolac on the prevention of CRBD in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP). All patients were randomly allocated to the ketorolac group or the control group. The primary outcome was CRBD above a moderate grade at 0 h postoperatively. CRBD above a moderate grade at 1, 2, and 6 h was also assessed. Postoperative pain, opioid requirement, ketorolac-related complications, patient satisfaction, and hospitalization duration were also assessed. The incidence of CRBD above a moderate grade at 0 h postoperatively was significantly lower in the ketorolac group (21.5% vs. 50.8%, p = 0.001) as were those at 1, 2, and 6 h. Pain scores at 0 and 1 h and opioid requirement over 24 h were significantly lower in the ketorolac group, while patient satisfaction scores were significantly higher in the ketorolac group. Ketorolac-related complications and hospitalization duration were not significantly different between the two groups. This study shows ketorolac can reduce postoperative CRBD above a moderate grade and increase patient satisfaction in patients undergoing RALP, suggesting it is a useful option to prevent postoperative CRBD.
Radical cystectomy, which is a standard treatment of muscle invasive and high-grade non-invasive bladder tumour, is accompanied with high rates of postoperative complications including major adverse cardiac events (MACE). Diastolic dysfunction is associated with postoperative complications. We evaluated perioperative risk factors including diastolic dysfunction related with MACE within 6 months after radical cystectomy. The 546 patients who underwent elective radical cystectomy were included. Diastolic dysfunction was defined as early transmitral flow velocity (E)/early diastolic mitral annulus velocity (e′) > 15. Logistic regression analysis, Kaplan-Meier survival analysis and log-rank test were performed. MACE within 6 months after radical cystectomy developed in 43 (7.9%) patients. MACE was related with female (odds ratio 2.546, 95% confidence interval 1.166–5.557, P = 0.019) and diastolic dysfunction (odds ratio 3.077, 95% confidence interval 1.147–8.252, P = 0.026). The 6-month mortality were significantly higher in the MACE group, and hospital stay and intensive care unit stay were significantly longer in the MACE group compared to the non-MACE group. Accordingly, preoperative diastolic dysfunction (E/e′ > 15) was related with postoperative MACE and MACE was related with 6-month survival after radical cystectomy. These results suggest that preoperative diastolic dysfunction can provide useful information on postoperative complications.
