Cyclopropane is an anesthetic inhalational agent. It is a liquid agent stored in orange colored cylinders at 75 psi and delivered as gas. Among other halogenated inhalational agents used in anesthesia, Cyclopropane is one which is stored in cylinders at room temperature. Some of the important properties and characteristics of it are discussed below. • It is […]
Methoxyflurane even though being the most potent anesthetic gas to be discovered till now, its use can been restricted due to the different complications that can arise from its usage. Below is a brief discussion on this inhalational agent. Physical Properties of Methoxyflurane • It has sweet odor. • It is non irritant. • It
Trilene anesthesia is a non-flammable, good analgesic-and cheap agent. Physical properties of trilene anesthesia : It has bp 80°C, VP 60 mm Hg, oil/gas coefficient 600 and blood/gas 12, metabolism 40%, unstable, preservative 1:10,000 thymol as stabilizer and coloured with waxoline blue 1 in 200,000, MAC 0.17%. Trilene anesthesia reacts with sodalime to produce phosgene
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
The kinetics of the anaesthetic agents during recovery from inhalant anesthesia are a reversal of the mechanism seen during induction. On cessation of anaesthetic agent, the fall in alveolar concentration is immediate. The gradient between venous blood and alveoli drives the anaesthetic into the alveoli. In terms of recovery from inhalant anesthesia , the poorly
Pentazocine injection is a synthetic narcotic analgesic derived from benzomorphan. Pentazocine Potency Its analgesic potency of 30 mg is said to be equal to 10 mg of morphine or 75 to 100 mg of pethidine. Pentazocine Dose The usual dose in adults is 20 to 60 mg i.m. (about 1 mg/kg). The oral dose ranges from
The Effects of Nitrous oxide in neuroanaesthesia has been questioned many times due to its detrimental effects on the cerebral vasculature and the brain tissue. However, there are no large-scale outcome studies to approve or disapprove its continued use in neuroanaesthesia. Nitrous oxide has been used in neuroanaesthesia for many years. Intraoperative analgesia with haemodynamic
Excess Oxygen can cause pulmonary oxygen toxicity which results in a lot of damage to the body tissues. To summarize briefly, the excess oxygen can cause, pulmonary toxicity, Acute respiratory distress syndrome, rertolental fibroplasia, convulsions and Paul burt effect. Here we will be dicussing the mechanisms of these tissue injuries that occur with use of excess oxygen. The following the changes
Introduction to Pediatric Weight Calculation Calculating the body weight of pediatric patients is a crucial skill for healthcare providers, particularly in emergency situations. Accurate weight estimation not only facilitates proper medication dosing but also ensures appropriate fluid administration. To streamline this process, guidelines from both the Pediatric Advanced Life Support (PALS) program and the World

The reduced cerebrovascular resistance at the site of Arteriovenous Malformations AVMs lead to an increase in blood flow to this area and the formation of a lower resistance shunt along with peri-infarction oedema. They usually represent a high-flow and low-resistance shunts with systemic arterial pressure more than the vascular intramural pressure ; so, rupture does
