Nitrous Oxide Effects the brain and induced analgesia or pain relief and anesthesia. Nitrous Oxide Effects includes the cardiovascular system as well. Nitrous oxide is a myocardial depressant and reduces the cardiac output. This is offset by an increase in sympathetic nerve activity resulting in peripheral vasoconstriction and thereby a minimal change in blood pressure. […]
First recognized 50 years ago and used as xenon gas anesthesia in 1957, used for orchidectomy in a 81- year-old. The patient woke up after 2 minutes. Xenon, a by-product of oxygen production during fractional distillation of air. It is said to be a noble gas and is present in air 0.0000087%. Rediscovered in 1990, it
The effect of Halothane on the liver is that it causes hepatitis called as halothane hepatitis. Incidence of massive hepatic necrosis as a result of halothane hepatitis is 1 in 35,000. Risk factors for halothane hepatitis are: Multiple exposures is single most important factor. Hypoxia. Middle age. Obesity. Females. Patient with other autoimmune diseases. Pathologic
One of the Isoflurane respiratory effects is that, Isoflurane causes bronchodilatation by inhibiting bronchoconstriction. As with other potent vapours, isoflurane impairs both ventilatory drive and hypoxic pulmonary vasoconstriction leading to hypercapnia and V/Q mismatch. In asthmatic patients due to its lack of arrhythmogenic potential, drugs like aminophylline or agonists such as salbutamol may be less
Introduction to Laparoscopic Appendicectomy Laparoscopic appendicectomy, a minimally invasive surgical procedure, has gained prominence as an effective treatment for acute appendicitis. This technique involves the use of small incisions and specialized instruments, allowing surgeons to remove the inflamed appendix with reduced trauma to the surrounding tissues. The primary indications for laparoscopic appendicectomy include acute appendicitis,

Enflurane is not a very commonly used agent in the developing counties although its usage is on in America. It is a newer inhalational agent like that of halothane. Enflurane is halogenated ether. Enflurane Physical Properties : It is a Colorless gas. It has ethereal odor. It is Non inflammable at clinical concentration but inflammable
High Flow oxygen delivery devices are also called as fixed performance devices because their performance is not affected by changes in patient’s tidal volume and respiratory rate and therefore deliver accurate oxygen concentration. High Flow oxygen devices are more effective in treating hypoxemia then low flow systems. Disadvantages of High Flow oxygen devices are: a. Low patient
What is Chloroform Chloroform is a very toxic compound, which was used in the past as an anesthetic agent. Chloroform use in anesthesia is only of historical value, although it still has some applications outside the medical practice. It was available as a liquid in bottles that would be poured on to a cloth and
