Chennai National Hospital has one of the best teams of Anaesthetists and Intensivists with many years of experience in providing patient care before, during, and after the surgery. General anesthetics bring about a reversible loss of consciousness and analgesia in order for surgeons to operate on a patient. Their use is commonplace, but how they produce their effect is still not fully understood. General anesthesia is, essentially, a medically induced coma, not sleep. Drugs render a patient unresponsive and unconscious. They are normally administered intravenously (IV) or inhaled. Under general anesthesia, the patient is unable to feel pain and may also have amnesia. Anaesthesia support for liver, heart and lung, kidney-pancreas, bone marrow transplants -managed by individuals with special expertise in these procedures. Analgesia during childbirth with epidurals and other suitable methods is provided by Obstetric Anaesthesiologists Some short therapeutic procedures or diagnostic studies such as MRI Scans, CT scans, and Endoscopy procedures require the presence and special skills of an Anaesthesiologist.
This phase occurs between the administration of the drug and the loss of consciousness. The patient moves from analgesia without amnesia to analgesia with amnesia.
The period following a loss of consciousness, characterized by excited and delirious activity. Breathing and heart rate becomes erratic, and nausea, pupil dilation, and breath-holding might occur. Because of irregular breathing and risk of vomiting, there is a danger of choking. Modern, fast-acting drugs aim to limit the time spent in stage 2 of anesthesia.
Muscles relax, vomiting stops and breathing is depressed. Eye movements slow and then cease. The patient is ready to be operated on
Too much medication has been administered, leading to brain stem or medullary suppression. This results in respiratory and cardiovascular collapse. The anesthetist's priority is to take the patient to stage 3 of anesthesia as quickly as possible and keep them there for the duration of the surgery.
