Ether effects all the systems of the body. A brief account is given below. Ether effects on Cardiovascular system: It does not depress myocardium rather it stimulates sympathetic system causing tachycardia and hypertension. Baroreceptor reflex is preserved with ether so ether can be used safely in patients with shock. Respiratory system: It does not depress respiration rather […]
There are several disadvantages of disadvantages of carbon dioxide : • High concentration causes narcosis. • It increases the cerebral blood flow and intracranial pressure. • It stimulates sympathetic nervous system, which may be dangerous in some patients already having systemic hypertension or myocardial ischaemia. • It sensitizes myocardium to externally administered catecholamines. • It
Isoflurane is a fluorinated methyl ethyl ether. It is an isomer of enflurane. Physical Properties of Isoflurane : • It is Colorless. • It has pungent ethereal odor so induction is not smooth. • Non inflammable, non explosive. • Vapor pressure similar to halothane (240 mmHg). Hence it also has agent specific Isoflurane vaporizer. Anesthetic
Diethyl ether anesthetic is the first volatile anesthetic agent used widely for over one-and-a-half centuries. Volatile anesthetic agents like Ether, ethylene, chloroform, trichloroethylene and methoxyflurane are not in use in developed countries. However, ether, trichloroethylene are still in use in some developing countries. Physical properties of Diethyl ether anesthetic : It has a boiling point
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,

Apart from the traditional tubes used for endotracheal intubation, other tubes like R.A.E tube, Endotrol tube and Double lumen tube. R.A.E. tube : The R.A.E. tube is named after the name of 3 scientists — Ring, Adair and Elwyn. R.A.E tube is of two types: • South facing: Used for upper cleft lip and cleft
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
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
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 Upper Respiratory Anatomy starts with the nose, which is an essential organ for breathing and conditioning of the air. The main respiratory functions of the nose are to provide passage to the air as well as the warming and moistening of the air. The next part is the pharynx, which is further divided into
