Fentanyl citrate injection is a potent narcotic analgesic and an opioid. It is said to be 100 times more potent than morphine and 1000 times more potent than pethidine. Fentanyl citrate injection effects It causes profound analgesia and sedation in a dose of 0.1 mg intramuscular. Like other narcotic analgesics it causes respiratory depression and is […]
The growth is reflected in the specialty of Neuroanesthesia Monitoring . These advances result in an abundance of data on which the treating physician can base his clinical decision. Every branch of medicine is advancing at a fast pace with the introduction of newer diagnostic modalities, treatment options and identification of more reliable prognostic indicators.
The Regulation of Respiration is mediated by various centers in the brain. They are: • Pneumotaxic centre in upper pons. • Apneustic centre in lower pons. • Ventral group of neurons in medulla (expiratory group). • Dorsal group of neurons in medulla (inspiratory group). Normally pneumotaxic centre has inhibitory effect on apneustic centre which otherwise
Laryngeal Mask Airway or LMA was discovered by Archies Brain so also called as a Brain Mask. LMA are special type of airways which are useful in difficult intubation. It is placed blindly in the oropharynx and the cuff is inflated with large volume of air tat is about 30 to 40 ml for a
Patients with primary neurodegenerative undergoing Anesthesia in Neurological Disease (Parkinson’s disease, Huntington’s chorea, Alzheimer’s, amyotrophic lateral sclerosis ) or demyelinating diseases (Guillain-Barre’ syndrome, multiple sclerosis, myeloneuropathies) suffer from progressive and sometimes incurable neurologic impairment, neuromuscular involvement, dysautonomia and pulmonary insufficiency. Elective surgery should be scheduled to coincide with periods of remission along with right application
Lesions requiring Cranial Base Surgery represent a heterogeneous group of lesions and vascular malformations associated with cranial base bony structures. These pathologies provide a challenging situation for both neurosurgeon and neuroanaesthesiologist. There is abundance of structures especially vital centers in a relatively smaller infratentorial space. Many patients present with signs and symptoms of brain stem
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
The Effects of Nitrous oxide in neuroanaesthesia has been questioned many times due to its detrimental effects on the cerebral vasculature and the brain tissue. However, there are no large-scale outcome studies to approve or disapprove its continued use in neuroanaesthesia. Nitrous oxide has been used in neuroanaesthesia for many years. Intraoperative analgesia with haemodynamic
Spirometer is the instrument used to measure following lung volumes. Normal Spirometry Values are very important and a good doctor especially an anesthetist should always remember the approximate values of them. The Normal Spirometry Values are: • Tidal volume is 400 to 500 ml (10 mI/kg). • Inspiratory reserve volume is is 2,400 to 2,600
Anesthesia Physics are the very basics that involve the application of the laws of physics in anesthesia. Some knowledge of Physics is very important for anesthetists in their daily practice. The following are the important gas laws in Anesthesia Physics: BOYLE’S LAW At a constant temperature, volume of gas is inversely proportional to the pressure CHARLE’S LAW
