What is Nitrous oxide gas ? Nitrous oxide gas is a Gaseous Anesthetic agent. Nitrous oxide gas is a colorless, inorganic gas with a sweet taste. The oxygen in the nitrous oxide molecule is not available for tissue respiration as nitrous oxide does not undergo significant decomposition in the body. Nitrous oxide gas, if administered
Cardiovascular effects of inhalation anesthetics occur on all aspects of cardiovascular function, namely, inotropic, chronotropic, dromotropic and lusitropic state of the heart. Their effects are as follows: a) Myocardial b) Coronary circulation c) Conduction d) Circulation Cardiovascular effects of inhalation anesthetics produce dose-related myodial depression of LV, RV and LA contractility as well LV diastolic

Charle’s Law: A Fundamental Gas Law What is Charle’s Law? Charle’s Law is a fundamental principle in thermodynamics that describes how gases behave under varying conditions of temperature and volume. Formulated by Jacques Charles in the late 18th century, this law states that the volume of a gas is directly proportional to its absolute temperature,
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
Postoperative Nausea and Vomiting (PONV) is one of the most distressing experiences associated with surgery, and many patients find it more troublesome than postoperative pain itself. It is not only very uncomfortable to the patient in the postoperative period but it also delays the time of starting enteral feeding and normal functions. Especially in day care
Trichloroethylene Trichloroethylene is also called as Trilene. It is an inhalational anesthetic gas, which was widely used until recently. It is still used in some developing countries because of its cheap cost compared to the other halogenated inhalational anesthetics. Trichloroethylene Physical Properties • It is colorless liquid. • Odor is sweet. • Mildly irritant. •
The Respiratory Tract anatomy is very essential for understanding the functions of a lung and hence should be known to every doctor. The Respiratory Tract anatomy starts with the oropharynx and the nasopharynx which are spaces in the mouth and the nose that act as conduit for the respiratory gases. At carina trachea divides into
Halothane Anesthesia is an alkane, halogenated hydrocarbon introduced in 1256. (M Johnston, UK). Physical Properties: Halothane Anesthesia is colorless, sweet smelling, nonirritating, bp 50 degrees C, VP 243 mm Hg, blood/gas 2.5, oil/gas 224, metabolism 20—40%, MAC in 02 ofQ7 /o and 0.29% with N20. It is relat Istable, decopcs on exposure tq.ajr, hence stored
Autonomic dysreflexia is an acute syndrome that frequently occurs in spinal cord injury (SCI) patients with a level usually above T6. It is characterized by excessive unmodulated sympathetic outflow in response to noxious stimuli below the spinal cord level. This can lead to dangerous elevations of blood pressure with disastrous clinical sequelae. Pathophysiology of Autonomic
One of the most dreaded Halothane Complications is hepatic injury. There are two types, the first which is a transient sub clinical type with increases in liver enzymes. Halothane Complications may occur due to decreased hepatic blood flow and reductive biotransformation. Secondly, fatal hepatic necrosis may occur up to one month after exposure. The National Halothane
