Nursing of Guedel airway

1. Keep the tube unobstructed

Suction sputum in time to clean up the respiratory tract to prevent aspiration or even suffocation Inhale high-concentration oxygen before and after suction, turn on the negative pressure device, insert No. 12 to 16 suction catheter to stimulate the patient to cough and then rotate to exit the suction catheter. Each suction time is controlled at about 15s to achieve the purpose of clearing the respiratory tract.

2. Strengthen the humidification of the respiratory tract

The outer mouth of the guedel airway is covered with a layer of saline gauze, which not only humidifies the airway but also prevents the inhalation of foreign bodies and dust. It can also be directly dripped into distilled water through the guedel airway at the right time, or 5-10ml of physiological saline can be slowly dripped in during sputum suction, and then sucked out, which can also achieve the purpose of humidification.

3. Oral care

In coma, the guedel airway can be continuously placed in the oral cavity, but the position should be changed every 2 to 3 hours, and the oral cavity and guedel airway should be cleaned every 4 to 6 hours to prevent clogging of the sputum. Replace the guedel airway once a day. After soaking and disinfecting the replaced oropharyngeal tube, dry it for later use.

Nursing of oropharyngeal airway during recovery from anesthesia

In general anesthesia patients after the operation, the effects of general anesthetics and muscle relaxants have not completely disappeared, and the protective reflex has not been fully recovered. They are often prone to airway obstruction, tongue fall, insufficient ventilation, vomiting, aspiration or unstable circulatory function And other complications. Therefore, some patients will place the guedel airway into the anesthesia recovery room after the tracheal intubation is removed after general anesthesia, and gradually recover under the careful observation of the nursing staff to prevent accidents.

1. Nursing during sputum suction

Effective sputum suction through the guedel airway is an important method for unconscious patients after general anesthesia to keep the airway open. Choose a suitable suction catheter, pay attention to the aseptic operation, act gently when sucking, the suction tube rotates from bottom to top to suck sputum, if the sputum is in the oral cavity or the position is shallow, suck the sputum in the oral cavity and upper airway first Then suck the sputum from the lower airway, and the sputum suction time should not exceed 15s. You should fully inhale oxygen before and after the sputum suction. If arrhythmia or difficulty breathing is found during sputum suction, cyanosis should pause sputum suction, and give oxygen until the symptoms are relieved. If the sputum is thick, spray inhalation should be given first, and the sputum should be diluted to facilitate better suction of sputum. .

2. The purpose of nursing

Keeping the airway open and placing the oropharyngeal airway can correct the patient's tongue drop, and can promptly suck out the sputum in the deep part of the airway, avoid airway obstruction, and keep the airway unobstructed

Strongly stimulating the cough reflex through the oropharyngeal airway suction tube to reach the airway deeper, stimulating the cough reflex is stronger, so that the sputum can be coughed to the upper respiratory tract, which is beneficial for sputum suction.

Reduce the irritation to the oropharyngeal mucosa and suck sputum through the oropharyngeal airway, which can avoid the oropharyngeal mucosa congestion, edema or injury and bleeding caused by negative pressure suction. It also reduces the aggravation of dyspnea caused by the injury and swelling of the oropharyngeal mucosa. Avoid hypoxia caused by sputum suction. Patients are often unable to breathe during negative pressure suction, which leads to hypoxia. Suction through the oropharyngeal airway. Oxygen can be given to the nasal catheter or the flow of oxygen can be increased to suck sputum. Oxygen can be continuously given during the process.
