a 25-year-old afghan male was presented to the emergency department with femoral shaft fracture following fall from the height. the patient was subjected to femoral nerve block and general anesthesia. first try for performing nerve block led to vascular puncture. therefore, the needle was removed and re-inserted 1 cm lateral to first puncture site and dex injected slowly with aspiration check a...

conclusions both dexmedetomidine and esmolol can be used as agents to control hypotension in patients undergoing lumbar spine decompression and fixation surgery; the dexmedetomidine group, however, was associated with better intraoperative hemodynamic stability and reduced intraoperative analgesic and volatile anaesthetic requirement. results the study results showed that dexmedetomidine had lo...

Factors associated with orthostatic hypotension such as age, drug induced hypotension, hypertension and diabetes mellitus have still been debatable. Most of previous studies were conducted in subjects 65 years or older, only a few were done in subjects from younger to older adults. The purpose of this study is to find the prevalence and predictor factors of orthostatic hypotension among adult p...

OBJECTIVE We tested the primary hypothesis that surgical site infections (SSIs) are more common in patients who had longer periods of intraoperative low blood pressure. Our secondary hypothesis was that hospitalization is prolonged in patients experiencing longer periods of critically low systolic blood pressure (SBP) and/or mean arterial pressure (MAP). BACKGROUND Hypotension compromises loc...

In sedentary individuals, postexercise hypotension after a single bout of aerobic exercise is due to a peripheral vasodilation. Endurance exercise training has the potential to modify this response and perhaps reduce the degree of postexercise hypotension. We tested the hypothesis that endurance exercise-trained men and women would have blunted postexercise hypotension compared with sedentary s...

We report a case with pheochromocytoma presenting as recurrent syncope due to hypotension. A 71-year-old man was admitted because of recurrent syncope and paroxysmal hypotension. He was diagnosed as having pheochromocytoma. In spite of a large volume of infusion and insulin therapy, syncope and paroxysmal hypotension continued. We speculated that hypotension was mainly due to vasodilatation cau...

BACKGROUND Outcomes associated with episodes of hypotension while hospitalized with acute decompensated heart failure are not well understood. METHODS AND RESULTS Using data from Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND-HF), we assessed factors associated with in-hospital hypotension and subsequent 30-day outcomes. Patients were classified as ...

SUMMARY Periprocedural hypotension, which frequently occurs during carotid artery stenting (CAS), is an important risk factor for complications such as stroke or death after CAS. To determine if a scoring model can be established to predict periprocedural hypotension (systolic blood pressure < or = 90 mm Hg) and prolonged periprocedural hypotension (requiring vasopressor for > 3 hours) in CAS, ...

BACKGROUND This study describes orthostatic and postprandial hypotension in elderly Parkinsonian patients and evaluates the effect of levodopa therapy on orthostatic and postprandial hypotension in these patients. METHODS Seventeen elderly patients with a clinical diagnosis of Parkinson's disease or Parkinsonism based on the U.K. Parkinson's Disease Society Brain Bank criteria (age range, 66-...

We explored whether severe or critical hypotension can be predicted, based on patient and resuscitation characteristics in out-of-hospital cardiac arrest (OHCA) patients. also the association of with mortality neurological outcome. conducted a post hoc analysis TTH48 study (NCT01689077), where 355 patients were randomized to targeted temperature management (TTM) treatment at 33 °C for either 24...
