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 […]
Desflurane mechanism of action is briefly studied. There is a dose-dependent suppression of EEG, at MAC greater than 1.66 the LEG becomes isoelectric. There is no evidence of epileptiform activity. It decreases the amplitude of somatosensory evoked potentials. There is a dose-dependent decrease in cerebral metabolism and cerebral vasodilatation. Cerebral autoregulation is impaired similar to
The anatomy of larynx is extremely important for an anesthesiologist. A through knowledge of the anatomy of larynx is essential for mastering the skill of intubation with a tracheal tube. Larynx is the organ of voice extending from the root of the tongue to trachea and lies opposite C3 to C6 vertebrae. The distance between
The metabolism of Sevoflurane complications yields fluoride ions, which if greater than 50 tmol/Iit is toxic. However, there are no reports of renal toxic effects. Compound A which is a degradation product when exposed to sodalime is also nephrotoxic, however this has not been clinically reported. It is safer to use flows greater than 2
Benzodiazepines or BDZ are compounds have largely replaced the barbiturates as hypnotics and act as sedatives, anticonvulsants, muscle relaxants and anesthetic agents. Mechanism of action of Benzodiazepines or BDZ Benzodiazepines or BDZ bind selectively to the a subunit of the GABA-A receptors surrounding the chloride channels in the CNS, a site distinct from that to which
The answer to the question what is Pulmonary Function Test should be known to every doctor. The Pulmonary function tests especially the bedside ones can be used by even a non medico to asses the function of the lung. 1. Simple Bed Side Test Now what is Pulmonary Function Test that can be used at
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

What is Buprenorphine injection? Is it an opiod? Buprenorphine is derived from the opium alkaloid thebaine and is closely related to morphine. It has powerful opiod agonist actions as well as partial opiod antagonist actions. It does not seem to cause addiction and physical dependence. Buprenorphine injection Potency It is a potent analgesic, 0.4 mg is equipotent
Nasotracheal Intubation can be accomplished by special nasal tubes or by simple oral tubes. It is a specialized technique in which the Endotracheal tube is passed in to the larynx via the nose rather than the mouth. A first the tube size is selected, which should be a size less than that used in the
