Using a hematocrit monitoring system and a Swan-Ganz catheter, the authors investigated the changes in blood volume and hemodynamic parameters before, during, and after dialysis-induced hypotension. When hypotension occurred, the cardiac output dropped sharply, and there were concomitant sudden decreases in the mean pulmonary arterial pressure and the mean right atrial pressure. These are attri...

BACKGROUND Fluid percussion injury (FPI) in piglets produces vasoconstriction of pial arteries (PAs), decreases in cerebral blood flow (CBF), and impairment of hypotensive autoregulation. Two types of angiotensin II receptors, AT1 and AT2, have been identified in the brain. This study characterized the effect of pretreatment with AT1- and AT2-selective antagonists on CBF and hypotensive autoreg...

Background: Fluid management strategies are one of the potential to prevent spinal induced hypotension in parturients scheduled for caesarean section. Objectives: This review will assess current evidence on fluid as a prophylactic measure hypotension. Methods: A narrative was conducted where Pubmed, Embase and Cochrane library were searched November 2021 RCTs, meta-analyses systematic reviews, ...

OBJECTIVE Anaphylaxis is the most severe form of radiocontrast media (RCM) induced hypersensitivity and can be life-threatening if profound hypotension is combined. With increased use of iodine based RCM, related hypersensitivity is rapidly growing. However, the clinical characteristics and risk factors of RCM induced anaphylaxis accompanied by hypotension (anaphylactic shock) are not clearly d...

CONTEXT Hypotension is one of the dose limiting side effects of benzodiazepines (BZDs), in particular of diazepam (DZP) which is still widely used in the clinic. Currently, only one FDA approved antidote exists for BZD overdose and novel approaches are needed to improve management of DZP overdose, dependency and withdrawal. OBJECTIVE Here, we hypothesized that increasing bioactive lipid media...

Hepatic encephalopathy (HE) is a debilitating neurological complication of cirrhosis. By definition, HE considered reversible disorder, and therefore should resolve following liver transplantation (LT). However, persisting complications are observed in as many 47% LT recipients. an invasive surgical procedure accompanied by various perioperative factors such blood loss hypotension which could i...

objective midazolam is a significant and effective drug for control of a life-threatening condition, generalized and partial refractory convulsive status epilepticus. the goal of this study was evaluation of midazolam efficacy for management of this serious disease and its two side effects, hypotension and respiratory failure. materials & methods our study was done using a quasi experimental me...

BACKGROUND Controlled induced hypotension guarantees less blood loss and better visibility of the surgical site. The impact of hypotension on post-operative cognitive functions is still being discussed. The objective of this study was to evaluate the effects of controlled induced hypotension on the cognitive functions of patients undergoing functional endoscopic sinus surgery (FESS). MATERIAL...

OBJECTIVE To show the clinical relevance of postprandial hypotension and to review its pathophysiology and management. DATA SOURCES Articles on postprandial hypotension were identified through MEDLINE and bibliographies of relevant articles. STUDY SELECTION All articles and case reports describing meal-related hypotension in the elderly and in patients with autonomic failure. DATA SYNTHES...
