Cerebral Aneurysm Clipping is one of the important modalities for the treatment of aneuryms apart from coiling so the anesthetic management of such cases is as follows. Skull is a fixed vault and most intracerebral structures are relatively in compressible, hence even a small haemorrhage can result in a significant anatomic distortion producing significant rise in ICP
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.
The history of anesthesia is very old. Anesthesia was used even in the ancient societies of the oldest civilizations wherein opium extracts, alcohol, coca leaves and other plant products were used. Even regional anesthesia in the form of compression on the nerve trunks, application of cold or use of crude local anesthetics was done in
Halothane cardiovascular effect plays a critical role. The main haemodynamic effect is a reduction in blood pressure secondary to a fall in cardiac output, reduced cardiac contractility and stroke volume, due to alterations in Ca-metabolism and a reduction in intracellular calcium. So, the coronary blood flow is reduced. The heart rate often falls due to
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
Methoxyflurane even though being the most potent anesthetic gas to be discovered till now, its use can been restricted due to the different complications that can arise from its usage. Below is a brief discussion on this inhalational agent. Physical Properties of Methoxyflurane • It has sweet odor. • It is non irritant. • It
There is very little airway irritation, hence used for inhalation induction especially in children. One of the halothane respiratory effects is that it is a potent respiratory depressant, reduces tidal volume and alveolar minute ventilation. The ventilatory response to raised Paco2 and reduced Pao, may be reduced due to depression of peripheral chemoreceptors in the
Halothane neuromuscular junction effect produces moderate muscle relaxation, it increases the degree and duration of relaxation produced by nondepolarizing muscle relax- ants. The action is at the postjunctional membrane. There is relaxation of the uterine muscle, which is useful in podalic version procedure but may hinder uterine contraction postpartum. Halothane neuromuscular junction effect may produce
One of the most dreaded Halothane Complications is hepatic injury. There are two types, the first which is a transient sub clinical type with increases in liver enzymes. Halothane Complications may occur due to decreased hepatic blood flow and reductive biotransformation. Secondly, fatal hepatic necrosis may occur up to one month after exposure. The National Halothane
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
