Desflurane cardiovascular effects are mentioned here. There is a decrease in systemic vascular resistance and peripheral vasodilatation. Cardiac depression, a dose-dependent tachycardia and fall in blood pressure are seen. Along with N20 this effect is minimal. Splanchnic and renal blood flow is preserved. Desflurane is a direct coronary vasodilator. A rapid increase in concentration of […]
Some of the toxicity issues related to desflurane toxicity is that, renal toxicity is not reported even after prolonged exposures and markers of renal function (albuminuria, glucosuria, urinary p-glutathione transferase, serum creatinine and BUN) were not altered after 7 days of exposure to 8 hours MAC of 1.25% desflurane. Desflurane Toxicity might occur at certain
Understanding Granisetron’s Use in Anesthesia for Nausea and Vomiting When undergoing anesthesia, one of the common side effects that patients may experience is nausea and vomiting. These unpleasant symptoms can not only cause discomfort but also delay the recovery process. To alleviate this, healthcare professionals may administer medications like granisetron. In this article, we will

Acoustic Surgery can be accomplished with suboccipital, translabyrinthine and middle fossa approaches. The sitting, supine, lateral or park-bench position can be used for the suboccipital approach. Small or medium sized tumours are associated with essentially no mortality, whereas large tumors (>4 cm) have mortality rates of 2-4%. Compromise of the anterior inferior cerebellar artery and
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
Sevoflurane metabolic effects are seen when approximately 5% of the dose is metabolized by the liver, catalyzed by cytochrome P450 (2E1) enzyme. While Sevoflurane metabolic effects are studied we see that, it is broken down to hexafluoro isopropanol (HFIP) and fluoride ions. Hexafluoro isopropanol is conjugated with glucuronic acid to form HFIP glucuronide and excreted
Circulatory system and Enflurane Mechanism Action : Enflurane reduces BP due to vasodilatation as a result of decrease in SVR and cardiac depression. There is increase in heart rate and reduction in cardiac output. It does not sensitize the heart to catecholamines or stimulate the sympathetic nervous system. The margin between adequate anaesthesia and unacceptable hypotension
Desflurane undergoes very little desflurane metabolism because of low blood/gas and low blood/tissue solubility. However, 0.02% is metabolized during desflurane metabolism with the production of trifluoroacetic acid which may interact with hepatic proteins and induce an immune response in susceptible patients. Previous exposure to halothane may produce antibodies. In desflurane metabolism , the elimination is almost exclusively by
The Bronchopulmonary Segments are the functional units of the lungs involved in he gaseous exchange. The lungs have the following Bronchopulmonary Segments on the right side: 1 Right main bronchus 2. Right upper lobe bronchus 3. Right middle lobe bronchus 4. Right lower lobe bronchus 5. Apical segment bronchus 6. Posterior segment bronchus 7. Anterior
Desflurane muscle relaxation chemical depresses the neuromuscular junction, it decreases the force of contraction of muscles and increases fade. Endotracheal intubation is possible. There is a potentiation of nondepolarizing muscle relaxants similar to isoflurane. There have been no reports of malignant hyperthermia in man but has been seen in animals. It is advisable to avoid
