Objectives: The aim of this study was to evaluate the effects oxidative stress on thiol-disulfide homeostasis caused by hypotensive anesthesia in mastoidectomy-tympanoplasty cases undergoing controlled hypotension. Methods: Fifty adult patients scheduled for mastoidectomy and tympanoplasty were included study. Anesthesia induced with lidocaine, propofol, rocuronium, remifentanil. maintenance co...

Objective Cardiotocography is widely used to assess fetal well-being during labour. The positive predictive value of current clinical algorithms identify hypoxia-ischaemia poor. In experimental studies, hypotension the strongest predictor hypoxic-ischaemic injury. Cohort studies suggest that deceleration area and capacity heart rate trace correlate with acidaemia, but it not known whether they ...

1. The aim of this study was to determine the effects of caffeine on haemodynamic and neurohumoral responses to meal ingestion in elderly patients with a history of symptomatic postprandial hypotension. 2. Postprandial hypotension is a common disorder of blood pressure regulation in the elderly, associated with falls and syncope. The pathophysiological mechanism is thought to be related to impa...

IN his lecture " Medicine, Yesterday and To-morrow ", Sir Henry Dale mentioned, as the most recent addition to the technique of preparing a patient for a surgical operation, synthetic substances which, by their action on the sympathetic ganglia, lower the arterial blood pressure and enable a postural adjustment of the patient to produce a practically bloodless field of operation (Dale, 1951). I...

a b s t r a c t a 36-year-old male patient with posttraumatic cervical cord damage and resultant quadriparesis, demonstrated hypotension and periods of bradycardia. for most of his two-month stay in the intensive care unit (icu), he was dependent on dopamine support to maintain hemodynamic stability. keeping in mind evidence from the literature, that electrostimulation of acupoints neiguan (pc ...
