Ethyl Chloride Anesthesia is a potent anesthetic. If it has a boiling point of 12.5°C and hence is a gas at room temperature, so it is liquefied and stored under pressure in a bottle with a cap and seal. It is used as a spray. Though ethyl chloride induces anesthesia quickly, the maintenance of a steady […]
N20 is minimally metabolized. Nitrous oxide metabolism shows us that N20 oxidizes the cobalt in vitamin B12, converting the monovalent form to bivalent form which fails to function as a methyl carrier. Nitrous oxide metabolism is an irreversible oxidation. Vitamin B12 is a cofactor for methionine synthetase and is involved in the production of 5,10
The diaphragm function is the most important determinant of the depth of respiration especially the inspiration. The Diaphragm is the muscle that separates the thorax from the abdomen. It is a thin sheet like muscle that has the right and the left crura. The diaphragm act as a partition between the two major cavities of the
Halothane Malignant hyperthermia syndrome may be triggered by halothane, it is an autosomal dominant inherited condition. There is a massive release of intracellular calcium from the sarcoplasm of the muscle. An increased metabolism results in rise in temperature of 2°C per hour, severe acidzsis, rhabdomyolysis, with associated hyperkalaemia. Mortality is 70%. Treatment is by active
The anesthesiologist should know that the essential element of an “anesthetic” for an Awake Craniotomy Anesthesia is the surgeon’s local anesthetic technique. Craniotomy is required for removal of space occupying lesions, intracranial vascular pathologies and for drainage of extradural or intradural haematoma. Most important postoperative considerations are regulation of patient’s ICP status, maintenance of cerebral
Flow Volume Loops are more sensitive and informative in detecting pulmonary diseases than conventional spirometry. Modem microprocessor controlled recording spirometers automatically generate these flow volume loops. The following are the parameters that are assessed in the Flow volume loops. TV= Tidal volume IRV = Inspiratory reserve volume IC = Inspiratory capacity ERV = Expiratory reserve
Surgery for small bowel obstruction is a very common emergency operation done in many hospitals. Intestinal obstruction is a blockage of your small intestine or colon that can prevent food and liquid through it. Intestinal obstruction can occur due to a number of conditions, including attachments in the abdominal tissue (adhesions), hernias and tumours or fibrous
Introduction to Obesity and its Challenges Obesity is a complex, multifactorial health condition characterized by an excessive amount of body fat, significantly impacting an individual’s overall health and well-being. Defined by a Body Mass Index (BMI) of 30 or higher, obesity has reached alarming prevalence rates worldwide, becoming a major public health concern. The World
Anesthesia Physics are the very basics that involve the application of the laws of physics in anesthesia. Some knowledge of Physics is very important for anesthetists in their daily practice. The following are the important gas laws in Anesthesia Physics: BOYLE’S LAW At a constant temperature, volume of gas is inversely proportional to the pressure CHARLE’S LAW
Patients with primary neurodegenerative undergoing Anesthesia in Neurological Disease (Parkinson’s disease, Huntington’s chorea, Alzheimer’s, amyotrophic lateral sclerosis ) or demyelinating diseases (Guillain-Barre’ syndrome, multiple sclerosis, myeloneuropathies) suffer from progressive and sometimes incurable neurologic impairment, neuromuscular involvement, dysautonomia and pulmonary insufficiency. Elective surgery should be scheduled to coincide with periods of remission along with right application
