Description

Tracheal catheter capable of performing airway surface anesthesia

Technical Field

The invention relates to the technical field of medical supplies, in particular to a tracheal catheter capable of performing airway surface anesthesia.

Background

Clinically, trachea cannula has cannula reaction of different degrees almost all during general anesthesia, and the main manifestation is: choking, rapid increase of heart rate, increase of blood pressure, and even acute cardiovascular and cerebrovascular events. In order to inhibit the choking reaction, the throat spraying component is mainly used for spraying local anesthetic on the throat part at present and then taking out the throat spraying component, and then trachea intubation is carried out. This also improves the endotracheal intubation response to some extent. However, the throat spray and the intubation tube are divided into two parts, the action is complicated, and the bleeding and swelling of the throat part can be aggravated by two operations, so that adverse effects are caused. Some perform thyrocricocentesis to reduce the reaction during intubation, but the thyrocricocentesis itself is also a invasive operation which can cause bleeding, severe choking cough, throat injury and severe cardiovascular reaction.

After emergency intubation, most patients need to be treated with a breathing machine for assistance under the action of analgesic and sedative or muscle relaxing medicines because the patients cannot tolerate the stimulation of tracheal intubation after ventilation. In addition, critically ill patients need to be supported by a ventilator with a long time, emergency intubation reaction is high for patients with respiratory obstruction, and in order to inhibit patients from tolerating tracheal stimulation reaction after intubation, a sedative and analgesic agent is required to be applied and then the ventilator is added to assist respiration. Almost all patients do not tolerate the stimulation of the tracheal catheter to the trachea, and the symptoms are blood pressure, fast heart rate, irritability, man-machine confrontation. Clinically, a large amount of analgesia and sedation or muscle relaxation agents are needed to inhibit the adverse reactions, which often is unfavorable for the observation of the disease and greatly increases the number of hospitalizations and thus the cost of the patient.

A significant portion of the analgesic and analgesic drugs used in surgery are also used to suppress the patient's tussive response to the endotracheal tube.
