BACKGROUND: Lung recruitment maneuver induces a decrease in stroke volume, which is more pronounced in hypovolemic patients. The authors hypothesized that the magnitude of stroke volume reduction through lung recruitment maneuver could predict preload responsiveness. METHODS: Twenty-eight mechanically ventilated patients with low tidal volume during general anesthesia were included. Heart rate, mean arterial pressure, stroke volume, and pulse pressure variations were recorded before lung recruitment maneuver (application of continuous positive airway pressure of 30 cm H2O for 30 s), during lung recruitment maneuver when stroke volume reached its minimal value, and before and after volume expansion (250 ml saline, 0...

BACKGROUND: Focused cardiac ultrasound (FoCUS) is accurate for determining the presence of a pericardial effusion. Using FoCUS to evaluate for pericardial tamponade, however, is more involved. Many experts teach that tamponade is unlikely if the inferior vena cava (IVC) shows respiratory variation and is not distended. CASE REPORT: A 53-year-old woman presented to the emergency department (ED) with severe orthostatic hypotension, exertional dyspnea, and hypoxia...

We report on the case of a young infant with chronic diarrhea that worsened and turned into hypovolemic shock with methemoglobinemia. We underline and discuss the main features of food protein-induced enterocolitis syndrome (FPIES). FPIES is a non-IgE-mediated food allergy involving tumor necrosis factor-alpha (TNF-α). Many triggering foods exist but cow's milk, as in the case reported herein, is one of the most frequent. It can start early or be delayed and start around the average age of 5 months. Symptoms are nonspecific with diarrhea and vomiting, but in the presence of methemoglobinemia, the diagnosis must be seriously considered...

BACKGROUND: Pre-hospital systemic vascular access with early resuscitation in the hypovolemic trauma patient can be problematic and is attempted through venous cut-downs, peripheral IV lines, and/or interosseous routes. This brief report examines an alternative for males via the corpus cavernosum (CC). METHODS: A systematic literature review using certain inclusion criteria including, but not limited to, corpus cavernosum access and resuscitation was conducted and a summary table created...

BACKGROUND: Shock may complicate several acute childhood illnesses in hospitals within low-income countries and has a high case fatality. Hypovolemic shock secondary to diarrhoea/dehydration and septic shock are thought to be common, but there are few reliable data on prevalence or treatment that differ for the two major forms of shock. Examining prevalence and treatment practices has become important since reports suggest high risks from liberal use of fluid boluses in African children...

We performed a retrospective analysis of the clinical features and patient outcomes for advanced-stage glassy cell carcinoma of the uterine cervix. The study was restricted to cases in which the glassy cell features constituted at least 95% of the biopsied specimen. During the study period, 675 patients were diagnosed with primary cervical carcinoma. Five (0.7%) of the 675 patients had cervical glassy cell carcinoma; of these, three were premenopausal, and two were postmenopausal. Abnormal vaginal bleeding was the most frequent presenting symptom...

INTRODUCTION: Prehospital, small-volume resuscitation of combat casualties with a synthetic colloid [6% hydroxyethyl starch (HES) 670/0.75] has been recommended when blood or blood components are unavailable. We studied hemostatic effects of a newer synthetic colloid (6% HES 130/0.4,) compared to either a natural colloid (albumin) or to crystalloids in an uncontrolled hemorrhage model. METHODS: Spontaneously breathing NZW rabbits (3.4±0.1 kg) were anesthetized, instrumented and subjected to a splenic injury with uncontrolled bleeding...

AIM: Some recent studies have reported that early intervention by a medical emergency team (MET) for clinical deterioration before intensive care unit (ICU) admission was associated with a survival benefit in critically ill cancer patients. We hypothesized that early MET intervention for an obstetric crisis in the general wards would be related to favorable outcomes in critically ill obstetric patients. METHODS: Data of obstetric patients who were managed by a MET were collected retrospectively from 1 March 2008 to 30 April 2015...

Dengue is a mosquito transmitted flaviviral infection which can give rise to severe haemorrhage (dengue haemorrhagic fever/DHF) and with capillary leakage induces hypovolemic shock (dengue shock syndrome/DSS). Although dengue symptoms and complications have been known for many decades there has only been one documented case of osteonecrosis of the maxilla which was treated by excision of the necrotic bone. In this case of dengue infection, extensive maxillary osteonecrosis and minimal root resorption appeared to follow factitious injury with a toothpick but resolved with nonsurgical management...

Dizziness is a common chief complaint in emergency medicine. The differential diagnosis is broad and includes serious conditions, such as stroke, cardiac arrhythmia, hypovolemic states, and acute toxic and metabolic disturbances. Emergency physicians must distinguish the majority of patients who suffer from benign self-limiting conditions from those with serious illnesses that require acute treatment. Misdiagnoses are frequent and diagnostic test costs high. The traditional approach does not distinguish benign from dangerous causes and is not consistent with best current evidence...

: Hemorrhagic rupture is a very rare complication of a simple hepatic cyst. We report the first case of a totally extraperitoneal rupture of a recurrent cyst, occurred in a 73-year-old man who presented with acute right hypochondralgia. Computed tomography revealed the rupture of a large hemorrhagic cyst in the right liver lobe and the formation of a voluminous hematoma in the retroperitoneal space. Despite the absence of hemoperitoneum, the entity of the bleeding led us to perform an urgent and successful surgical intervention...

BACKGROUND: Young patients with diabetes present with reduced compensatory responses to hypovolemic stress. Less compliant veins could be a contributing factor, since roughly two-thirds of the blood volume resides in the venous system as a blood reservoir, adjusting proper venous inflow to the heart. The aim of this study was to measure venous compliance and lower limb blood pooling during hypovolemic stress, and to correlate them to indices of diabetes severity and glucose control. METHODS: Fifteen young women with type 1 diabetes (DW) and 18 healthy age-matched women (C) were subjected to lower body negative pressure (LBNP) (11-44 mmHg), creating hypovolemic stress...

Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral damage. This study was designed to assess internal carotid artery blood flow (ICA-BF) during simulated hypovolemia and noninvasive positive pressure ventilation (PPV) in young healthy humans. Beat-by-beat blood velocity (ICA and aorta) were measured by Doppler ultrasound during normovolemia and simulated hypovolemia (lower body negative pressure), with or without PPV in 15 awake subjects...
