Post operative hypoxia is caused by several factors : I. General—patient’s factors Exaggerated preoperative problems such as: • Extreme obesity • Geriatric age • Pre-existing cardiopulmonary disease 2. Diminished inspired oxygen • Lack of oxygen supplementation devices • Excessive suctioning • Diffusion hypoxia after nitrous oxide 3. Impaired ventilatory inefficiency • Obstructed upper airway […]
Solid organ transplantation is the therapy of choice for patients with end-organ failure. Despite numerous advances in the field, the number of individuals awaiting solid organ transplantation continues to exceed the supply of organs. One approach to increasing the supply of organs is to maximize donation rates of eligible patients. Family consent rates for donation
Cauda equina syndrome arises from compression of the lumbosacral nerve roots. Large herniated lumbar intervertebral discs are the most common culprit. Other sources of compression include spinal or sacral fractures or surgery common in ICU trauma patients, lumbosacral neoplasms, spinal stenosis, nonneoplastic masses such as cysts, peripheral neuropathy, and infectious processes. Low back pain is
There are numerous uses of carbon dioxide in modern anesthesia. It is used : • To increase depth of anesthesia with volatile anesthetic agents by stimulating respiration.- • To increase cerebral blood flow during carotid artery surgery. • To produce hyperventilation during blind nasal intubation. • To stimulate the respiration after artificial hyperventilation. • It
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
Missed injuries, commonly referred to as the trauma surgeon’s nemesis, are an expected occurrence in the management of multiply injured patients. The definition of a missed injury is institution specific. Generally speaking, however, a missed injury is an injury identified at some defined time after the initial assessment. Missed injuries are not frequently life-threatening. However,
Nitrogen is present in the atmosphere and it constitutes 78.08% of total air. Moreover, the use of nitrogen is growing very rapidly these days. Use of nitrogen in medicine is helpful as it can be used as diluent of oxygen in order to avoid oxygen toxicity. It is stored in either compressed air or in
The Emergency Medical Treatment and Active Labor Act (EMTALA Act) was passed by the U.S. Congress in 1986 to prevent hospitals from rejecting, refusing, or transferring patients because they are unable to pay or because they have public health insurance. The main purpose of EMTALA Act is to ensure nondiscriminatory patient access to emergency medical
Hyperbaric oxygen therapy is currently used in various clinical treatment regimens like for treating carbon monoxide poisoning. These include decompression sickness, carbon monoxide poisoning, cyanide poisoning, gas embolus, gas gangrene, resistant anaerobic infections, and threatened split-thickness skin grafts. The mechanism of action in treating carbon monoxide poisoning purportedly involves increasing tissue oxygenation, which increases collagen
According to the chest pain guidelines the faster the diagnosis can be made and the occlusion reversed, the more likely the patient is to salvage myocardial tissue and benefit from improved outcomes. Cardiovascular disease is a dominant cause of morbidity and mortality in the United States and acute myocardial infarction (MI) is one of the
