The present study compared the efficacy of preloading with colloid "Haemaccel" with vasoconstrictor (intravenous ephedrine sulphate) in preventing hypotension during propofol induction. This prospective, randomized study included 120 patients of Amercan Society of Anaesthesiologists (ASA) physical status I and II ageing 21 to 50 years of both gender coming for routine surgery. Patients were ran...

Arterial blood pressure was recorded directly in 11 normotensive subjects, in 11 patients with essential hypertension and in 10 patients with renovascular hypertension. The pressor response to intravenous injections of norepinephrine, tyramine, angiotensin and ephedrine was compared in these three groups. An infusion of angiotensin was then given and the pressor response to injections of norepi...

medication was discontinued. However, there was a suggestion that the recovery period might be somewhat longer in asthmatic adults than in children. To determine whether the effects of oral sympathomim&ic agents on leukocyte cyclic AMP responses might differ in normal and asthmatic subjects, a comparison was made of the effects of short-term treatment with ephedrine in the two groups. All subje...

BACKGROUND Ingestion of a combination of 5 mg x kg(-1) caffeine (C), and 1 mg x kg(-1) ephedrine (E) was reported to have an ergogenic effect on high intensity aerobic exercise performance, but 25% of the subjects experienced vomiting and nausea while engaging in hard exercise after the treatment. The present study was undertaken to investigate whether reduced levels of C+E would alleviate the ...

As potential activators of brown adipose tissue (BAT), mild cold exposure and sympathomimetic drugs have been considered as treatments for obesity and diabetes, but whether they activate the same pathways is unknown. In 10 healthy human volunteers, we found that the sympathomimetic ephedrine raised blood pressure, heart rate, and energy expenditure, and increased multiple circulating metabolite...

Phenylephrine is effective for the management of spinal anesthesia-induced hypotension in parturients undergoing cesarean delivery under spinal anesthesia. While ephedrine was previously considered the vasopressor of choice in obstetric patients, phenylephrine is increasingly being used. This is largely due to studies suggesting improved fetal acid-base status with the use of phenylephrine as w...

In congenital myasthenic syndrome with DOK7 mutations ephedrine was reported to be beneficial in single patients. We carried out a small, open and prospective cohort study in eight European patients manifesting from birth to 12 years. Five patients showed limb-girdle and facial weakness, three a floppy infant syndrome with bulbar symptoms and/or respiratory distress. Ephedrine was started with ...

The objective of this study was to determine whether ephedrine, an alpha- and beta-adrenergic agonist previously shown to enhance genital blood flow in women, has beneficial effects in reversing antidepressant-induced sexual dysfunction. Nineteen sexually dysfunctional women receiving either fluoxetine, sertraline, or paroxetine participated in an eight-week, double-blind, placebo-controlled, c...
