The Dose-response of Intrathecal Ropivacaine Co-administered with Sufentanil for Cesarean Delivery under Combined Spinal-epidural Anesthesia in Patients with Scarred Uterus.

Background: Spinal anesthesia is considered as a reasonable anesthetic option in lower abdominal and lower limb surgery. This study was to determine the dose-response of intrathecal ropivacaine in patients with scarred uterus undergoing cesarean delivery under combined spinal-epidural anesthesia.

Methods: Seventy-five patients with scarred uterus undergoing elective cesarean delivery under combined spinal-epidural anesthesia were enrolled in this randomized, double-blinded, dose-ranging study.

Penile fibrosis in intracavernosal prostaglandin E1 injection therapy for erectile dysfunction.

Penile fibrosis (PF) may be a complication of intracavernosal injection therapy (ICI). It has been well documented as a side effect of papaverine, but there have been few reports associating penile fibrosis with prostaglandin E1 (PGE1, Alprostadil). Many authors did not find fibrotic changes in the penis while others reported penile fibrosis as a complication of intracavernosal PGE1 in only 0.

The use of the vacuum erection device in the management of erectile impotence.

A retrospective survey was conducted to assess the use, efficacy and acceptance of the Vacuum Erection Device (VED) among 60 impotent men not satisfied with intracavernosal injection therapy. Forty three (72%) men filled out the questionnaires. Thirty nine (81%) of the men abandoned the device, the main reason being that 'it did not work'.

Does compression of the base of the penis improve the efficacy of intracavernosal injection of prostaglandin E1 for impotence? A randomized controlled study.

The objective of this study was to evaluate the effect on erections of impeding venous blood flow following intracavernosal injections of prostaglandin E1. Dispersion of injected X-ray contrast medium indicated that application of the RMRI penile clamp to the base of the penis retarded venous outflow. The clamp was then tested in impotent men to determine whether their erectile response was enhanced.

The role of intracavernosal vasoactive agents to overcome impotence due to spinal cord injury.

Twenty-two spinal cord injured men (mean age 35.2 years) referred because of impotence were treated with intracavernosal vasoactive agents. Papaverine 2-20 mg, papaverine 40 mg plus phentolamine 0.

Effects of a sclerosant, ethanolamine, on the venous drainage system of the dog penis.

To explore the possibility of using venous sclerosant therapy to overcome venogenic impotence we studied the effects of ethanolamine on the veins draining the dog penis. Following injection of the sclerosant into the deep dorsal vein radiological and histological evidence of occlusion was obtained but by one month recanalization of thrombi had occurred and collateral venous channels had formed. These findings cast doubt on the effectiveness of this sclerosant as a means of treating impotence.

The male menopause. Fact or fancy?

Men over 50 may experience a decline in sexual, physical and intellectual potency. In many respects this is analogous to the menopause, hence the term male menopause. Although this term suggests profound hormonal changes and loss of reproductive capacity these do not occur in men.

Effects of acute alcohol on penile tumescence in normal young men and dogs.

To determine the cause of the inhibition of sexual function observed in normal subjects with elevated blood alcohol concentrations (BAC), nocturnal penile tumescence (NPT) was monitored in 11 subjects over three consecutive nights. On the third night alcohol was administered (BAC = 0.154 g/100 mL).

Prostaglandin E1 therapy for impotence, comparison with papaverine.

The efficacy of prostaglandin E1 as a pharmacological treatment of erectile dysfunction (impotence) was compared with the standard treatment, papaverine, in a single blind, crossover trial. A total of 129 impotent men received intracavernous injections of either prostaglandin E1 (5 micrograms) or papaverine (18 mg.) 1 month apart.

Complications associated with penile implants used to treat impotence.

The complications associated with a variety of penile prostheses used in the treatment of 302 men with erectile dysfunction are described. Infection of the prostheses resulted in their removal from 11 patients (3.6%), antibiotic therapy and replacement in five men.

Treatment of impotence by intrapenile injections. A comparison of papaverine versus papaverine and phentolamine: a double-blind, crossover trial.

The efficacy of papaverine, and a combination of papaverine and phentolamine as a pharmacological treatment of impotence was compared in a double-blind, crossover trial. A total of 40 impotent men received intracavernous injections of papaverine (40 mg.) or a combination of papaverine (20 mg.

Treatment of impotence by intrapenile injections of papaverine and phenoxybenzamine: a double blind, controlled trial.

The efficacy of papaverine and phenoxybenzamine as a pharmacological treatment of impotence was compared in a double blind, crossover, placebo controlled trial. Thirty-four impotent men received intra-cavernosal injections of papaverine (60 mg), phenoxybenzamine (6 mg) or normal saline (10 ml) at monthly intervals. Observations by EJK up to 45 minutes after injection demonstrated that papaverine caused full erections in 35% of men and partial erections in 62%.

Experience in the management of erectile dysfunction using the intracavernosal self-injection of vasoactive drugs.

We report the results of a survey of 75 patients with erectile dysfunction, all of whom were treated by self-injection of the corpora cavernosa with vasoactive agents. At the time of the survey each patient had been self-injecting at home for at least 3 months. Of the patients 62 were followed for 3 to 21 months.

Prolonged erections following intracorporeal injection of medications to overcome impotence.

We describe the management of 17 men who developed prolonged erections following the intracorporeal injection of vasoactive drugs (e.g. papaverine) for the treatment of erectile dysfunction.

Experience with the Nesbit procedure in the treatment of penile curvature.

Thirteen men who had undergone Nesbit's operation for penile curvature were assessed to determine the efficacy of the procedure. Ten patients had Peyronie's disease and three had a congenital curvature. Follow-up ranged from 8 months to 28 months.
