PURPOSE: Trendelenburg positioning is commonly used to temporarily treat intraoperative hypotension. The Trendelenburg position improves cardiac output in normovolemic or anesthetized patients, but not hypovolemic or non-anesthetized patients. Therefore, the response to Trendelenburg positioning may vary depending on patient population or hemodynamic conditions. We thus tested the hypothesis that the effectiveness of the Trendelenburg position, as indicated by an increase in cardiac output, improves after replacement of a stenotic aortic valve...

We present a patient who developed black esophagus secondary to hypovolemic shock and was placed on total parenteral nutrition for three weeks after hospital discharge. The area of interest is the multimodal approach used in treatment of this noncompliant patient. Even with a high mortality rate, this case illustrates a successful outcome of a patient who responded to appropriate immediate therapy resulting in complete resolution of the necrosis with no further development of complications.

BACKGROUND: We have previously shown that treatment with valproic acid (VPA) decreases brain lesion size in swine models of traumatic brain injury (TBI) and controlled hemorrhage. To translate this treatment into clinical practice, validation of drug efficacy and evaluation of pharmacologic properties in clinically realistic models of injury are necessary. In this study, we evaluate neurologic outcomes and perform pharmacokinetic analysis of a single dose of VPA in swine subjected to TBI, hemorrhagic shock, and visceral hemorrhage...

Severe exercise-associated hyponatremia (EAH) is largely dilutional, whereas contributions of sodium loss remain equivocal. We present a case of EAH with encephalopathy involving an experienced male cyclist with no recollection of the event. We thereby conducted a retrospective analysis of biochemical trajectories during hospital recovery. The normalization of serum [Na], in context with changes in other variables, offered a 'reverse' perspective of the underlying pathophysiology. The following biochemical changes were temporally observed, with the return of normonatremia: 1) a decrease in serum potassium and calcium concentrations (absence of extracellular fluid dilution); 2) a decrease in total protein, blood urea nitrogen, hematocrit and hemoglobin (plasma volume expansion); and 3) an increase in mean platelet and red cell corpuscular volumes (cellular expansion after total body water and sodium deficits)...

Uterine fibroids in pregnancy present with numerous complications. However, spontaneous rupture is a rare and potentially life-threatening event. We report a case of a 43-year-old multiparous woman who presented with hypovolemic shock secondary to a ruptured uterine fibroid 2 days after a spontaneous vaginal delivery. Emergency laparotomy confirmed massive intra-abdominal hemorrhage from the ruptured capsule of a 10-cm subserosal fibroid. A myomectomy was performed. Her postoperative recovery period was uneventful...

Background: Dengue can cause increased vascular permeability that may lead to hypovolemic shock. Endothelial dysfunction may underlie this; however the association of endothelial nitric oxide pathways with disease severity is unknown. Methods: We performed a prospective observational study in two Vietnamese hospitals, assessing patients presenting early (<72 hours fever) and patients hospitalized with warning signs or severe dengue. The reactive hyperaemic index (RHI), which measures endothelium-dependent vasodilation and is a surrogate marker of endothelial function and NO bioavailability was evaluated using peripheral artery tonometry (EndoPAT) and plasma levels of L-arginine, Arginase-1 and ADMA were measured at serial time-points...

OBJECTIVE: Systemic capillary-leak syndrome is a very rare cause of recurrent hypovolemic shock. Few data are available on its clinical manifestations, laboratory findings, and outcomes of those patients requiring ICU admission. This study was undertaken to describe the clinical pictures and ICU management of severe systemic capillary-leak syndrome episodes. DESIGN, SETTING, PATIENTS: This multicenter retrospective analysis concerned patients entered in the European Clarkson's disease (EurêClark) Registry and admitted to ICUs between May 1992 and February 2016...

Acute hemorrhagic hypovolemic shock is caused by a significant high blood loss and leads to hemodynamic instability. The decrease in intravascular volume results in cellular hypoxia and finally in damage to organs such as the liver and the kidney. The liver plays a decisive role in the development or prevention of multiple organ failure after hemorrhagic shock. Despite the large number of experimental studies, the knowledge of pathophysiological mechanisms in the liver after hemorrhagic shock is incomplete...

Hemoperitoneum with hypovolemic shock from avulsion of a pedunculated leiomyoma is a rare but highly fatal condition that can occur spontaneously or as a result of trauma. We report a case of hemoperitoneum and hypovolemic shock secondary to a bleeding leiomyoma detected via computed tomography (CT) scan in a 39 year old premenopausal, gravida 0 female that presented with abdominal pain and became hemodynamically unstable in the emergency department. A preoperative bimanual exam revealed a mass consistent with a 20 week gestational uterus...

Spontaneous ruptures of the inferior vena cava (IVC) are rare. The mortality rate is high associated with all IVC injuries despite prompt resuscitation or operation. We present a case of 68-year-old women with spontaneous IVC dissection, presented as acute chest pain. Chest CT demonstrated a large amount of hemopericardium, and dilated inferior vena cava (IVC), suggesting cardiac tampon. Subsequently, hypovolemic shock and cardiac arrest occurred. After resuscitation, abdomen CT angiography was taken to find bleeding focus...

OBJECTIVE: Hyponatremia is associated with increased mortality, but the mortality associated specifically with SIAD is not known. We hypothesised that mortality in SIAD was elevated, but that it was less than in hypervolemic(HEN) or hypovolemic(HON) hyponatremia. DESIGN: Mortality rates are presented as risk ratios(RR),with 95% confidence intervals (CI), and compared to normonatremic controls(NN). METHODS: Prospective, single center, non-interventional study of all patients with hyponatremia(≤ 130 mmol/l) admitted to hospital...

PURPOSE OF REVIEW: A discussion of recent research exploring the feasibility of perfusion-guided resuscitation of acute circulatory failure with a focus on lactate and microcirculation. RECENT FINDINGS: Upon diagnosis of shock, hyperlactemia is associated with poor outcome and, under appropriate clinical circumstances, may reflect inadequate tissue perfusion. Persistent hyperlactemia despite resuscitation is even more strongly correlated with morbidity and mortality...

The differential diagnosis of acute abdominal pain in pregnancy is broad and can be complicated by atypical manifestations that are due to the anatomic distortions and physiologic changes of pregnancy. Due to the lack of clinical understanding, angular pregnancy does not appear to be recognized as a clinical entity and many cases are likely to go undiagnosed. This is a case report of a 34-year-old woman who was referred to the obstetrics emergency department with sudden abdominal pain and in a state of hypovolemic shock...

Hyponatremia is the most common electrolyte disorder among hospitalized patients and it is sometimes considered as a poor outcome predictor. Its correction is thus indicated, even in asymptomatic patients. The conventional treatment is represented by fluid restriction in presence of euvolemia or hypervolemia; whereas loop diuretics are used in some hypervolemic conditions (cardiac heart failure, liver cirrhosis and nephrotic syndrome) and intravenous isotonic or hypertonic solution are administered in hypovolemic conditions...

Total gastric necrosis is a rare disease and easy to misdiagnose. Here we report a rare case of total gastric necrosis. The patient, an 89-year-old male, had epigastric pain for 5 days. He was transferred to our hospital because of intraperitoneal hemorrhage and hypovolemic shock. We performed an emergency laparotomy. During the surgery, we found a total of 3500ml unclotted blood in the abdomen, splenic infarction and gastric necrosis. Total gastrectomy with Roux-en-Y esophagojejunostromy and splenectomy was performed...

BACKGROUND: The aim of this case series is to describe the experience of using the non-pneumatic anti-shock garment (NASG) in the management of severe Postpartum hemorrhage (PPH) and shock, and the value of implementing this concept in high-complexity obstetric hospitals. METHODS: Descriptive case series of 77 women that received NASG in the management of PPH with severe hypovolemic shock from June 2014 to December 2015. Vital signs, shock index (SI), the lactic acid value and the base deficit were compared before and after NASG application...

The microcirculation is responsible for blood flow regulation and red blood cell distribution throughout individual organs. Patients with circulatory shock have acute failure of the cardiovascular system in which there is insufficient delivery of oxygen to meet metabolic tissue requirements. All subtypes of shock pathophysiology have a hypovolemic component. Fluid resuscitation guided by systemic hemodynamic end points is a common intervention. Evidence shows that microcirculatory shock persists even after optimization of macrocirculatory hemodynamics...

BACKGROUND: Surfing is an increasingly popular activity and surfing-related injuries have increased accordingly. However, to the best of our knowledge, there are no reports of penetrating upper airway injuries in surfers. We present a "cannot ventilate, cannot intubate" situation following penetrating neck injury by a surfboard fin. CASE PRESENTATION: A previously healthy 29-year-old Japanese man was swept off his board by a large wave and his left mandible, tongue root, and right epipharynx were penetrated by the surfboard fin...

Massive lower gastrointestinal from primary isolated ilio-rectal fistula is a rare condition and difficult to diagnosis and emergency surgery for this situation has a high mortality rate. This report describes a successful operation in an 88-year-old man at present with massive lower gastrointestinal hemorrhage from ilio-rectal fistula and hypovolemic shock. Underlying diseases are prostate cancer, hypertension, dyslipidemia, aortic stenosis, mitral valve stenosis and chronic renal disease. Operative treatment is to explore laparotomy with internal iliac artery ligation and rectal resection...

INTRODUCTION: Cirrhosis of the liver is known for its high risk of mortality associated with episodes of acute decompensation. There is an even greater risk in patients that present with acute-on-chronic liver failure. The identification of patients at higher risk for adverse outcomes can aid in making the clinical decisions that will improve the prognosis for these patients. AIMS: To determine in-hospital mortality and evaluate the epidemiologic and clinical characteristics of patients with cirrhosis of the liver seen at a tertiary referral hospital...
