Problems solved by technology

The stimulation of the endotracheal tube to the trachea is mainly due to the pressure and stimulation of the air bag inflated by the endotracheal tube to the trachea, and the local anesthetic is applied before the endotracheal intubation, and may be damaged during the intubation

Abstract

An air tube catheter capable of accurately performing local anesthesia comprises an air tube and an air bag wrapping the air tube, the air bag is of a double-layer structure so that the inner-layer air bag can be inflated, the outer-layer air bag can be drenched, and a plurality of small holes are formed in the outer surface of the outer-layer air bag so that the inner-layer air bag can extrude the outer-layer air bag so that anesthetic can be extruded out of the small holes.

Description

technical field [0001] The invention relates to a tracheal tube capable of accurate local anesthesia. Background technique [0002] Stress response refers to a kind of sympathetic nerve-adrenal medulla system excitation and hypothalamus-adrenal cortex secretion increase that occurs when the body is subjected to noxious stimuli. A series of pathophysiological processes that change. The clinical manifestations are increased heart rate and increased blood pressure, which can cause arrhythmia and myocardial ischemia in patients. Related studies have shown that the concentrations of epinephrine (E) and norepinephrine (NE) in the blood plasma of patients under general anesthesia increase during and after tracheal extubation. Especially at the time of tracheal extubation, the cardiac index, pulmonary vascular resistance and peripheral vascular resistance of the patients all increased significantly. The causes of stress response during general anesthesia and extubation include th...
