Effect of lumbar-epidural administration of tramadol on lower urinary tract function,,

NEUROUROLOGY AND URODYNAMICS, Issue 1 2008

Abstract Aims Intrathecal and epidural administration of µ-agonist opioids is associated with urinary retention, a potentially serious adverse-event. In animal studies tramadol has been found not to affect voiding function. We evaluated urodynamic effects of epidural tramadol in humans. Methods Fifteen adults planned for cystoscopy under local-anesthesia underwent urodynamics (UDS) at baseline and 30 min after administration of 100 mg tramadol in lumbar-epidural space. UDS consisted of filling cystometry, pressure-flow study and pelvic floor electromyography (EMG). Subsequently, all underwent cystoscopy and were observed for 6 hr. Results After injection of tramadol, a significant rise was observed in bladder capacity (391.8,±,179.6 ml vs. 432.7,±,208.8 ml; P,=,0.019) and compliance (60.1,±,51.5 ml/cm H2O vs. 83.0,±,63.0 ml/cm H2O; P,=,0.011) without a significant change in filling pressure (22.5,±,13.2 cm H2O vs. 24.1,±,15.1 cm H2O; P,=,0.576). Filling sensations were delayed significantly (P,,,0.05). EMG during filling phase showed a significant fall (P,=,0.027). Peak flow-rate (Qmax), average flow-rate, postvoid residue and detrusor pressure-at-Qmax did not show significant change from baseline (P,>,0.05). Three patients had bladder outlet obstruction which did not worsen after the injection. Guarding reflex was inhibited in seven out of 12 patients who had it at baseline (P,=,0.016). Conclusions Epidural tramadol increases the bladder capacity and compliance and delays filling-sensations, without ill effect on voiding. This seems true even for patients with obstructed outflow; however, due to small number of patients a definite conclusion cannot be derived. These results will guide clinician to avoid catheterization in cases where epidural tramadol is used for postoperative pain. The inhibitory effects of tramadol on EMG activity are intriguing and need further studies. Neurourol. Urodynam. © 2007 Wiley-Liss, Inc. [source]

Improved Cancer Pain Treatment Using Combined Fentanyl-TTS and Tramadol

PAIN PRACTICE, Issue 4 2007
Franco Marinangeli MD
,,Abstract: The aim of the study was to facilitate dose escalation of strong opioids. In this randomized open-label study the influence of tramadol on dose adjustment of transdermal fentanyl in advanced cancer pain control was prospectively evaluated. Seventy patients affected by intractable cancer disease with visual analog scale (VAS) score >3 were enrolled. Thirty-five patients were treated conventionally with increasing transdermal fentanyl dosage as required (group F) and 35 patients received oral tramadol added to their transdermal fentanyl before each increment of the transdermal opioid dosage (group T). Pain control was equally satisfactory in the two groups. VAS scores at baseline (T: 4.36 ± 1.53; F: 4.51 ± 1.36; n.s.) and at the end of the study (T: 1.8 ± 1.6; F: 1.6 ± 1.5; n.s.) did not differ. However, in the tramadol group this level of pain control was achieved with much slower dose escalation of fentanyl. The mean application time of the fentanyl-Transdermal Therapeutic System patch for each dosage (25, 50, 75 ,g/hour) was significantly greater in patients receiving tramadol. No patient in group T escalated to the 100 ,g/hour patch, while in 12 patients of group F the 100 ,g/hour patch was applied after a 75 ,g/hour patch mean application period of 18.6 ± 4.7 days. The number of fentanyl-TTS dosage changes was significantly lower in group T (1.2 ± 0.4 vs. 2.3 ± 0.5; P < 0.05). The mean total duration of treatment in group T, was 37.1 ± 11.6 days. The amount of fentanyl used at study end was 56.6 ± 11.2 ,g/hour plus 141.1 ± 151.9 mg tramadol per day (median: 200 mg/day) in group T patients compared with 84.1 ± 12.2 ,g/hour in group F patients (P < 0.05). The combination of a strong opioid with a weak opioid to treat severe cancer pain allowed a more gradual increase of analgesic delivery than was possible using fentanyl-TTS alone, minimizing periods of under- and overdosing. In addition, it considerably slowed the pace of fentanyl dose escalation. In conclusion, this TTS fentanyl-tramadol analgesic protocol provides a useful alternative to the usual treatment of cancer pain with fentanyl-TTS alone, especially in case of quick progression of disease and pain.,, [source]

A comparison of tramadol and pethidine analgesia on the duration of labour: A randomised clinical trial

Background: The ideal obstetric analgesia should provide analgesic efficacy without attenuation of uterine contractions. Aims: To compare the outcome of intramuscular administration of pethidine and tramadol in labour analgesia. Methods: One hundred and sixty full-term parturients were randomly assigned to two equal groups in active labour. Group P received 50 mg pethidine; and group T, 100 mg tramadol intramuscularly. Primary outcome measure was the duration of the labour. The analgesic efficacy, maternal side-effects, mode of delivery, maternal satisfaction and Apgar score as the secondary outcome were assessed. Results: The duration of labour was shorter in group T, for first stage (190 vs 140 min; P < 0.0001) and for second stage (33 vs 25 min; P = 0.001). There were no differences in Groups P and T with respect to median (7 vs 8) and maximum (7.5 vs 8) visual analog scores (VAS) for pain at 10 min and one hour after drug administration. Women in group P had lower VAS pain scores than those in group T in the second stage of labour (8 vs 9; P = 0/009). There was a significantly higher incidence of nausea and vomiting (35% vs 15%; P = 0.003) and drowsiness (80% vs 29%; P < 0.0001) in group P. Conclusion: Both 100 mg tramadol and 50 mg pethidine provide moderate analgesia in first stage of labour. Tramadol seems to cause a shorter duration of labour and lower incidence of maternal side-effects. However, its analgesic efficacy was not found to be as effective as pethidine, especially in the second stage of labour. [source]

Safety and efficacy of tramadol in the treatment of idiopathic detrusor overactivity: a double-blind, placebo-controlled, randomized study

Aim To evaluate the efficacy and safety of tramadol in patients with idiopathic detrusor overactivity (IDO). Methods A total of 76 patients 18 years or older with IDO were randomly assigned to receive 100 mg tramadol sustained release (group 1, n = 38) or placebo (group 2, n = 38) every 12 h for 12 weeks. Clinical evaluation was performed at baseline and every 2 weeks during treatment. All patients underwent urodynamics and ice water test at baseline and 12-week treatment. Main outcome measures were number of voids per 24 h, urine volume per void and episodes of urge incontinence per 24 h on a frequency volume chart and detailed recording of adverse effect. Results After 12 weeks of treatment mean number of voids per 24 h ± SD decreased from 9.3 ± 3.2 to 5.1 ± 2.1 (P < 0.001 vs. placebo) [95% confidence interval (CI) ,5.1-,0.4]. At that time mean urine volume per void increased from 158 ± 32 to 198 ± 76 ml (P < 0.001 vs. placebo) (95% CI 8-22), while mean number of incontinence episodes per 24 h decreased from 3.2 ± 3.3 to 1.6 ± 2.8 (P < 0.001 vs. placebo) (95% CI ,2-0.3). Tramadol induced significant improvements in urodynamic parameters. More adverse effects were associated with tramadol treatment than with placebo (P < 0.05). The main adverse event with tramadol was nausea. Conclusions In patients with non-neurogenic IDO tramadol provided beneficial clinical and urodynamic results. Further studies are required to draw final conclusions on the efficacy of this drug in IDO. [source]
