Minimization of the risk of aneurysm rupture during Anesthesia for Cerebral Aneurysm demands smooth induction and maintenance of optimum transmural pressure (TMP) gradient. TMP is the difference between mean arterial pressure (MAP) and ICP. Rise in MAP or fall in ICP affects transmural pressure gradient thereby increasing the risk of rupture of the aneurysmal sac.
Surgery for small bowel obstruction is a very common emergency operation done in many hospitals. Intestinal obstruction is a blockage of your small intestine or colon that can prevent food and liquid through it. Intestinal obstruction can occur due to a number of conditions, including attachments in the abdominal tissue (adhesions), hernias and tumours or fibrous
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
Anesthesia for Interventional Neuroradiology has progressed from minimally invasive therapy to complex interventional radiology. In the past, anesthesiologists used to be called for resuscitation after some catastrophe had occurred. Interventional neuroradiology (or endovascular neurosurgery) is the radiologically guided endovascular approach to lesions of the central nervous system or its related circulatory structures to deliver therapeutic
N20 is minimally metabolized. Nitrous oxide metabolism shows us that N20 oxidizes the cobalt in vitamin B12, converting the monovalent form to bivalent form which fails to function as a methyl carrier. Nitrous oxide metabolism is an irreversible oxidation. Vitamin B12 is a cofactor for methionine synthetase and is involved in the production of 5,10
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
When it comes to total knee replacement surgery, managing pain and providing effective analgesia is of utmost importance. The procedure itself can be quite invasive and painful, and it is crucial to ensure that patients are comfortable and experience minimal discomfort throughout their recovery process. In this article, we will explore the various options available
The Non Rebreather Masks are the masks that do not allow rebreathing of the gases to take place when a patient is ventilated or he takes spontaneous breaths while the mask is being held. These masks of Non Rebreather type need to have a very high flow of oxygen as most of the oxygen is being lost.
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
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
