metabolic acidosis and severe hypotension are the main causes of irreversibility during hemorrhagic shock. the influence of these two factors on durations of shock period and survival time were studied in four groups of anesthetized cats. in group i the animals were made hypotensive by reducing mean arterial blood pressure (pa) to 45 mmhg with concurrent metabolic acidosis. [n group ii the same...

the aim of this study was to assess the effect of spinal block with low dose of bupivacaine and sufentanil on patients with low cardiac output who underwent lower limb surgery. fifteen patients who had ejection fraction less than 40% (group 1) were compared with 65 cases with ejection fraction more than 40% (group 2) in our study. our subjects underwent spinal block with 7.5 mg hyperbaric bupiv...

Spinal cord injury is a devastating chronic condition resulting in temporary or permanent motor,sensory or autonomic dysfunction of the cord. The manifestation of spinal cord injury based onthe severity and involved areas could be different. Numerous studies have demonstrated thatbradycardia, hypotension, and orthostatic hypotension are present insignificant number ofpat...

This review describes the steps and conclusions from development validation of an artificial intelligence algorithm (the Hypotension Prediction Index), one first machine learning predictive algorithms used in operating room environment. The has been demonstrated to reduce intraoperative hypotension two randomized controlled trials via real-time prediction upcoming hypotensive events prompting a...

This case study discusses the incidence of a paraneoplastic autonomic neuropathy in an elderly male who had otherwise negative work-up for their aetiology orthostatic hypotension. illustrates importance trying to correctly identify hypotension, which is often overlooked, and frequently diagnosed as idiopathic. Orthostatic hypotension most prevalent populations can be debilitating, leading highe...
