Blind nasal intubation is the technique of intubation wherein a nasotracheal tube is passed into the trachea through the nose, without visualization of the glottis with laryngoscope. This is an advanced method that can be carried out only in experienced and skilled hands especially like those of the anesthetists. A blind nasal intubation should always
There are numerous uses of carbon dioxide in modern anesthesia. It is used : • To increase depth of anesthesia with volatile anesthetic agents by stimulating respiration.- • To increase cerebral blood flow during carotid artery surgery. • To produce hyperventilation during blind nasal intubation. • To stimulate the respiration after artificial hyperventilation. • It
There are 4 types of Hypoxia . The 4 types of Hypoxia are as follows: 1. Anoxic hypoxia or Diffusion hypoxia Anoxic hypoxia also called as diffusion hypoxia is essentially due to the deficiency of oxygen being absorbed by the lungs. This is either due to a decrease in the inspired concentration of oxygen in the air
Withdrawal from alcohol is a serious and common complication associated with hospitalization that can result in the condition known as delirium tremens. Many patients who consume alcohol cease drinking on or prior to admission for both voluntary and involuntary reasons. A patient does not need to be an alcoholic by medical definition to be at
Many drugs are metabolized to active metabolites. This is usually carried out by the liver in the form of reductions, oxidations, and the addition of methyl, acetyl, and other groups. watchesbest.org While metabolites are usually a fraction as potent as the parent compound, in some situations they may be more potent and may accumulate to
Common health effects of carbon dioxide include : • There is fall in peripheral vascular resistance but there is increase in mean arterial pressure. There is increase in blood flow towards skin and so more chances of oozing. • Directly it reduces contractile force of heart but indirectly increases cardiac output. It increases the sympathetic
Carbon dioxide was discovered by Von Helmont and was isolated by Joseph Black in 1757. Physical properties of carbon dioxide were shown by Yandell Henderson in 1925 and J S Haldane in 1926. It was frequently used to stimulate respiration and there was provision for carbon dioxide cylinders on old Boyle’s machines. The physical properties of
Extubation is the process of removal of an Endotracheal tube from a patient. A person is usually put on endotracheal tube if he is unconscious so as to protect his airways or to ventilate the person if he is not breathing adequately. Intubation is also the best method to secure an airway even in the
In adult with normal hemoglobin and hematocrit blood losses more than 20% of their blood volume (or hematocrit falls below 30%) are to be replaced with blood (while in western countries replacement may be required on loss more than 25 to 30%). A few important indications of transfusion of blood are mentioned below. • Losses
