Cranial Perfusion Pressure is the blood pressure in the brain that is required to maintain adequate circulation in the brain and thus maintain the important cerebral functions. Very low Perfusion Pressure in the brain will result in inadequate circulation to the brain and reduced oxygen and glucose supply to the brain with which it functions. The
Nitric oxide Inhalation may cause selective reversible dose-dependent pulmonary vasodilatation. It improves ventilation and perfusion of lungs, so beneficial in adult respiratory distress syndrome. It helps to reduce pulmonary vascular resistance in patients with primary pulmonary hypertension. It was known to be atmospheric pollutant produced by internal combustion of engines. It possesses various biological functions—there
Most common causes of acute respiratory distress syndrome ARDS cause a clinical condition called as ARDS first described by Ashbaugh in 1967, to describe a group of patients with acute inflammation of the lungs resulting in severe hypoxia that is not amenable for correction by oxygen therapy. The reported incidence of ARDS is about 1.5—13.5% per 100,000

The four most common embolism seen in the critical care patient population are air embolism, fat embolism, cholesterol embolism, and blood embolism (clots). Embolism is an uncommon complication of altered mentation after invasive procedures, but it must be placed on the list of differential diagnoses. Air embolism occurs when air enters the systemic vascular circulation
Blind nasal intubation is the technique of intubation wherein a nasotracheal tube is passed into the trachea through the nose, without visualization of the glottis with laryngoscope. This is an advanced method that can be carried out only in experienced and skilled hands especially like those of the anesthetists. A blind nasal intubation should always
Dextrans are a type of colloids and are used for intravenous transfusion. The Dextran Injection is aavailable as Dextran 70 (mol. wt. 70,000 Daltons), Dextran 150 (mol. wt. 1,50,000 Daltons) and Dextran 40 (mol. wt. 40,000 Daltons). Dextrans are polysaccharides. These solutions can be stored for 10 years. Half life of dextrans is 2 to
Dural tear is a known complication of spinal surgeries, such as laminectomies, spinal fusions, and disc excisions. It most commonly occurs in the lumbar region. In general, the tear is noted at the time of operation when leakage of cerebrospinal fluid (CSF) is noted by the surgeon. A tear in the dura results in decompression
The postoperative management of a kidney transplant recipient requires meticulous monitoring of urine output and electrolyte levels. Renal allografts will not necessarily make urine as soon as they are reperfused. Depending on the particular center, the incidence of delayed graft function ranges from 5% to 15% in cadaveric and from 0% to 5% in live

The European—American Consensus Conference in 1993 provided working definitions of Acute Lung Injury and ARDS to improve diagnostic consistency and interpretation of the results of clinical and epidemiological studies. Both Acute Lung Injury and ARDS are characterized by the presence of hypoxemia and pulmonary infiltrates without elevated left atrial pressure. The two conditions are distinguished
Extubation is the process of removal of an Endotracheal tube from a patient. A person is usually put on endotracheal tube if he is unconscious so as to protect his airways or to ventilate the person if he is not breathing adequately. Intubation is also the best method to secure an airway even in the
