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 […]
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
Some of the toxicity issues related to desflurane toxicity is that, renal toxicity is not reported even after prolonged exposures and markers of renal function (albuminuria, glucosuria, urinary p-glutathione transferase, serum creatinine and BUN) were not altered after 7 days of exposure to 8 hours MAC of 1.25% desflurane. Desflurane Toxicity might occur at certain
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
Neuroleptanalgesia Neuroleptanalgesia is method of IV anesthesia which combines at neuroleptic drug with opioid analgesic drug. The most favored combination is neuroleptic droperidol and the analgesic fentanyl. The combination used neuroleptanalgesia induces state which is different from usual general anesthesia. Because the patient is awake during surgery and is cooperative during the operative and surgical
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.
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

Pethidine injection is a synthetic morphine like analgesic. this opioid medication has about one tenth as powerful compared to morphine. This drug has sedative and tranquilizing effects also. It may cause euphoria and sleepiness. Unlike morphine it tends to relax smooth muscles and thus relieves most types of pain associated with plain muscle spasm. But
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
The anesthesiologist should know that the essential element of an “anesthetic” for an Awake Craniotomy Anesthesia is the surgeon’s local anesthetic technique. Craniotomy is required for removal of space occupying lesions, intracranial vascular pathologies and for drainage of extradural or intradural haematoma. Most important postoperative considerations are regulation of patient’s ICP status, maintenance of cerebral
