BACKGROUND AND OBJECTIVES: Hepatic infarction is characterized by parenchyma ischemic necrosis involving at least two acinis. It is extremely uncommon due to the arterial and portal venous blood supply. We report a case of a patient not know to have diabetes who developed massive areas of ischemic infarcts of the liver after episode of acutely diabetes decompensated. CASE REPORT: A 67 year-old hypertensive female who has been presenting, for the last 10 days, polydipsia, high urinary volume, visual and gait impairment, nausea and vomiting was admitted to the emergency room (ER)...

Gasometry is the measurement of dissolved gases in the blood, by measuring pH, carbon dioxide pressure (pCO(2)), serum bicarbonate (HCO(3-)), and lactate and serum electrolytes: sodium, potassium and chlorine you can make a diagnosis, etiology and treatment in the critically ill patient. The aim is to provide five steps for the interpretation of blood gases by: 1. The definition of acidemia or acidosis, or alkalemia or alkalosis. 2. Defining the metabolic component or respiratory. 3. To determine the anion gap; levels above 15 ± 2 determine other likely causes of excess anions (methanol, uremia, diabetic ketoacidosis, paraldehyde, ionized, lactic acidosis, ethylene glycol and salicylates...

BACKGROUND: The metabolic changes in trauma patients with shock contribute directly to the survival of the patient. To understand these changes better, we made a rigorous analysis of the variations in the main examinations requested for seriously polytraumatized patients. METHODS: Prospective analysis of patients with blunt or penetrating trauma with hypovolemic shock, with systolic arterial pressure (SAP) equal to or lower than 90 mmHg at any time during initial treatment in the emergency room and aged between 14 and 60 years old...

PURPOSE: To evaluate the protective action of alpha-tocopherol in ischemia/reperfusion injuries of pelvic member of rats. METHODS: Thirty adult male rats of the Wistar strain were randomized into three experimental groups of 10: Group I--control group with no ischemia or reperfusion. Groups II and III--four hours of ischemia and of hours of reperfusion by means of clamping of the infrarenal aorta. The animals of Group II were treated with saline and those of Group III were treated with i...

INTRODUCTION: Continuous replacement therapy of renal function has gained acceptance over the last decade for the treatment of acute renal failure. In the present study we present our experience using continuous hemodialysis (CHD) in our institution. PATIENTS AND METHODS: This is a prospective analysis of the CHD treated patients in the intensive care unit (ICU) of our institution over an 24-month period. CHD was performed through a double-lumen catheter such as Mahurkar...

The utilization of 12 neonatal intensive care technologies was recorded in 193 patients. An index of utilization (Pu) was adopted to classify these technologies into three sub-groups corresponding to low (Pu < 15%), medium (15% < or = Pu < or = 85%), and high (Pu > 85%) intensity of use. No models were developed for technologies with high intensity of use (intravenous hydration, warming, micro-haematocrit, heart rate monitoring). Multiple linear regression was used to predict the utilization of technologies with medium intensity of use (gasometry, oxygen hood, CPAP, mechanical ventilation), and multiple logistic regression was used with the same purpose for technologies with low intensity of use (exchange transfusion, bicarbonate, adrenaline, echocardiography)...

A technique of anesthesia is considered for laryngoscopy in suspension, and certain acts of surgery of the vocal cords, e.g. myxoma, and of the trachea, e.g. destruction of papillomatosis. The patient is in apnea, unventilated, a catheter brings down to the level of the carena a current of oxygen of 15 liters per minute, the gaseous acidosis is buffered by injections of a solution of molar sodium bicarbonate. After briefly recalling the notions which justify this technique, its repercussion on homeostasis is studied by arterial gasometry...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
