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
Introduction to Sevoflurane Sevoflurane is a volatile inhalational anesthetic agent that has gained significant acceptance in modern medical practice, especially for its application in both adult and pediatric anesthesia. As a halogenated ether, its chemical structure features a combination of fluoroalkyl and ether groups, which contributes to its unique properties. Its molecular formula is C4H03F7,
Cardiovascular effects of inhalation anesthetics occur on all aspects of cardiovascular function, namely, inotropic, chronotropic, dromotropic and lusitropic state of the heart. Their effects are as follows: a) Myocardial b) Coronary circulation c) Conduction d) Circulation Cardiovascular effects of inhalation anesthetics produce dose-related myodial depression of LV, RV and LA contractility as well LV diastolic

Posterior fossa is a tight infratentorial compartment which harbors vital centers like cerebellum, pons and medulla. Anesthesia for Posterior Fossa Surgery is employed in carious types of space-occupying lesions, i.e., cerebellar tumours, cerebellopontine angle lesions, medulloblastoma, brainstem glioma occur in this area. The patients with posterior fossa tumor presents with features of raised intracranial pressure, brain
Chronic pain is a persistent condition that affects millions of people worldwide. It can be debilitating and significantly impact a person’s quality of life. Fortunately, there are various strategies and approaches available to help manage chronic pain effectively. In this article, we will explore some of the commonly used chronic pain management strategies. 1. Medication:

General Anesthesia mask is used to ventilate the patient without intubation or before intubation. The mask significantly increases amount of dead space. These are available in sizes from 0 to 4 numbers. Face mask should be made of antistatic rubber. At the bottom of General Anesthesia mask there is air filled cuff which has soft cushioning effect.
In severe lung infections, the respiratory system is significantly compromised, making it difficult for patients to get enough oxygen into their bloodstream and remove carbon dioxide. This can lead to respiratory failure, a life-threatening condition where the body’s vital organs do not receive the oxygen they need to function properly. Mechanical ventilators, also known as

In Isoflurane cardiac function , the effect is that the cardiac output is maintained due to the slight increase in heart rate reflexly due to hypotension. There is a dose-dependent decrease in arterial pressure due to peripheral vasodilatation and myocardial depression, less than that due to halothane. There is a selective coronary vasodilatation and decrease
Functioning of Isoflurane cerebral blood flow is discussed here. Isoflurane reduces cerebral metabolism and so the oxygen consumption is reduced. At 1 MAC there is a 23% reduction in CMRO2. Isoflurane cerebral blood flow is not associated with seizure activity as opposed to Enflurane. The EEG shows progressive development of slow waves after an initial
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
