The Poynting effect refers to the phenomenon where mixing of liquid nitrous oxide at low pressure with oxygen at high pressure (in Entonox) leads to formation of gas of nitrous oxide. So oxygen and nitrous oxide both are present in gaseous state in Entonox cylinder. In anesthesia practice the Poynting effect is seen in the
The metabolism of Sevoflurane complications yields fluoride ions, which if greater than 50 tmol/Iit is toxic. However, there are no reports of renal toxic effects. Compound A which is a degradation product when exposed to sodalime is also nephrotoxic, however this has not been clinically reported. It is safer to use flows greater than 2
Nitrous oxide induction agent is a weak anaesthetic agent and not suitable as a sole anaesthetic agent. Nitrous oxide induction agent is used to hasten inhalational induction of anaesthesia due to its “concentration and second gas effects”. There is a smooth and pleasant induction. The recovery from anaesthesia is rapid; however, a “diffusion hypoxia”
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
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
The Importance of Mechanical Ventilators in Severe Lung Infections Read More »
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.
Halothane Malignant hyperthermia syndrome may be triggered by halothane, it is an autosomal dominant inherited condition. There is a massive release of intracellular calcium from the sarcoplasm of the muscle. An increased metabolism results in rise in temperature of 2°C per hour, severe acidzsis, rhabdomyolysis, with associated hyperkalaemia. Mortality is 70%. Treatment is by active
Nasal Intubation can be accomplished by special nasal tubes or by simple oral tubes. Advantages of nasal intubation over oral intubation: 1. Better fixation and therefore less chances of accidental extubation. 2. No possibility of tube occlusion by biting. 3. Better oral hygiene can be maintained. 4. Oral feeding is possible. 5. Better tolerated by
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
Understanding Minute Ventilation in Anesthesia and Intensive Care In the field of anesthesia and intensive care, minute ventilation plays a crucial role in ensuring the well-being and safety of patients. Minute ventilation refers to the volume of air that is moved in and out of the lungs in one minute. It is a vital parameter
