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 […]
Clinical studies using this strategy have claimed that even Normal Cerebral Perfusion Pressure values as low as 50 mm Hg are well tolerated with 8% mortality, and good recovery at 6 months after injury with little or moderate disability in 80% of patients. An increase in MAP may increase brain oedema. Therefore, lower intravascular pressures
Phenoperidine a new opoid Phenoperidine is chemically related to pethidine and is similar to fentanyl. It is one of the new opioids available now for use in anesthesia for analgesia and as a pre anesthesia medication. Phenoperidine potency One milligram of this new opioid drug is equianalgesic to 100 mg pethidine. Phenoperidine Onset and Duration of
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

Analeptic Drugs are Cenrtral nervous system stimulants or CNS stimulants that stimulate respiration and also the brain. The different Analeptic Drugs are: Bemegride Nikethamide Doxapram These drugs help to restore the drug-induced depressed function towards normal. Ideally there should be pharmacological antagonism and the analeptic drug should block the depressant drug activity either by inactivation or
Entotracheal intubation is a life saving technique used frequently in emergencies and in operation theaters. Hence, the Intubation Indications need to be known to all doctors. The Major intubation indications are as follows: For ventilation of the patient: When the patient is unconscious or in a state of apnoea, where he is not breathing, Intubation
A lot of anesthetic gases can be dangerous when used in a low alveolar ventilation anesthesia. This is because the anesthetic gases can combine with soda lime or other components of the boyles machine and produce poisonous gases. It is also known as low flow anesthesia where low fresh gas flow is set in a closed circuit or a semi closed
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
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,
Nitrous oxide inhalation anaesthetic is a gaseous inhalation agent first described in 1799 by Hamphrey Davy and introduced by Horace Wells (1846), a dentist, into clinical use in the US and it is still in use. Physical properties: Nitrous oxide inhalation anaesthetic is a colourless, sweet smelling and non-irritant gas, bp-88°C, slightly heaver than air.
