What is Morphine sulphate Morphine sulphate injection is an opium alkaloid and a standard potent opioid analgesic. This opioid acts as an anxiolytic, hypnotic and sedative. It causes both the stimulation and the depression of the central nervous system. The depression caused by morphine leads to analgesia, respiratory depression, depression of cough reflex and sleep
The effect of Halothane on the liver is that it causes hepatitis called as halothane hepatitis. Incidence of massive hepatic necrosis as a result of halothane hepatitis is 1 in 35,000. Risk factors for halothane hepatitis are: Multiple exposures is single most important factor. Hypoxia. Middle age. Obesity. Females. Patient with other autoimmune diseases. Pathologic
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
Halothane Cerebral effects include cerebral vasodilatation and increases cerebral blood flow (CBF). A concentration of I MAC doubles CBF and 1.6 MAC quadruples the CBF. Cerebral autoregulation may be abolished and cerebrospinal fluid (CSF) production reduced by 30%. The cerebral oxygen consumption (CMRO,) may be reduced by 25%. There is no epileptiform activity in the
Introduction to Long-Term Venous Access Long-term venous access is a vital component of modern medical treatment, allowing healthcare providers to administer therapies over extended periods. This method is particularly significant in scenarios requiring frequent or continuous access to the bloodstream, such as chemotherapy for cancer patients, dialysis for those with kidney dysfunction, and long-term antibiotic
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
McNarry and Goldhill compared ACDU Scale (Alert, Confused, Drowsy, Unresponsive) and AVPU scale (Alert, responds to Voice, responds to Pain, Unresponsive) by the American college of surgeons with GCS scale for neurological assessment of critically ill ward patients. Just like GCS the ACDS Scale is a method to assess the neurological status and level of
Below is an answer to the simple question what is sleep? What is Sleep? Physiologically, sleep is regarded as absence of wakefulness, where the responses to environmental stimuli are greatly reduced. But, in fact, it is an active state, related to definite anatomic structures as well to specific biogenic amines. Yet, its exact mechanism is
Acute barbiturate poisoning causes depression of the CNS, particularly the respiratory system causing decreased breathing, and the cardiovascular system causing a peripheral circulatory collapse. The frequent and often fatal complications are respiratory (atelectasis, pulmonary edema and bronchopneumonia) or renal (acute renal shutdown). Treatment of acute barbiturate poisoning The severity of barbiturate poisoning is assessed by
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
