Choking is one of the clinical emergencies in psychiatry. Often, when eating suddenly occurs when you can not speak or serious choking, painful performance, and finger mouth or pharynx, the patient’s lips and face cyanosis, breathing is extremely difficult, often inspiratory (obstructive) respiratory distress, such as encountering such patients, the first consideration to the possibility of choking, should be decisive to take strong first aid measures. Resuscitation measures Patients found to be choking should be rescued in situ, scrambling to immediately pick out the food accumulated in the mouth and pharynx with a hand or spoon, and encourage coughing or spitting out food for patients who are conscious. If the patient is unconscious, stimulate the throat with a spoon or chopsticks to induce vomiting or place the patient in a lateral position with the head down at 45° and tap the back of the chest to assist the patient to spit out the food. First aid technique: when the patient is suffocating, place the patient on his side, push the patient’s abdomen with his hands or both hands above the chest, impact 6 to 10 times, repeatedly, this method suddenly increases the intra-abdominal pressure, but also the use of the diaphragm upward impact, so that the food blocking the airway moves up or out of the trachea. Severe asphyxia: the patient’s position should be immediately changed to lying down, padded shoulders, so that the head is tilted back, and a coarse puncture needle (16-20 gauge needle) is taken urgently under the laryngeal node (1 to 2 cm of the lower edge of the cricoid cartilage) to pierce the trachea steadily and accurately, which can suspend respiratory distress and hypoxia. So as to buy resuscitation time. The tracheal intubation or tracheotomy should be prepared by quickly contacting with the Department of Five Gases. So that the airway obstruction is completely cleared. Care and precautions 1. Observe the condition: After the patient’s airway obstruction is cleared, the changes of the patient’s consciousness, mouth and lips, and breathing should be closely observed. The patient’s hypoxic state is gradually relieved, respiration is stable, face and mouth and lips turn rosy, and consciousness is restored clearly, indicating that there are no residues in the airway, while vital signs should be monitored and recorded on the nursing sheet. After the choking patient resumes spontaneous breathing, complications may occur, such as: aspiration pneumonia, then the patient should be observed for 1 to 2 days for high fever, cough, cough, lung woven (13) purple to take. 2, do a good job of psychological care: the patient suddenly choke when eating, no psychological preparation. When resuscitated successfully after recovery of consciousness, recalling the choking scene is often perceived mental tension, anxiety, fear of psychological, fear of eating again, and in severe cases, refusal to eat. At this time, nursing staff should take the initiative to warmly comfort the patient, explain the condition and the importance of diet, guide the patient to face the reality, relieve the ideological concerns, eliminate the negative emotions, help the patient to get rid of emotions such as anxiety, boredom, fear and fear. Also work closely with the patient’s family to reduce the patient’s psychological pressure and make them treat their diet correctly. 3, strengthen the management of key patients’ diet, mental patients should eat in groups, closely observe and prevent the occurrence of choking. It is strictly forbidden to bring food back to the ward. For patients who cannot eat alone, nursing staff must be alone on-site care, help patients to divide and chop some coarse food, educate patients to eat less per mouthful, chew slowly. At the same time, according to the characteristics of the patient’s condition, such as manic patients, patients with extreme excitement, hyperphagia, snatching food or forcibly swallowing without chewing fine. The diet structure should be adjusted to avoid spiny foods and sticky foods such as fish and rice cakes. If there is obvious difficulty in swallowing, a person should be assigned to take care of the patient, and the nursing staff should feed carefully and slowly, strictly control the speed of eating, and give semi-liquid or liquid diet. Or give nasal milk, intravenous nutrition, etc. as prescribed by the doctor to ensure the nutritional intake and safety of the patient. 4, timely treatment of adverse drug reactions, long-term use of antipsychotic drugs mostly have extrapyramidal reactions, in serious cases, can cause ataxia of the pharyngeal muscle groups, swallowing response, or esophageal muscle paralysis, resulting in choking when the patient eats. Once adverse drug reactions are detected, antagonistic drugs should be given, such as scopolamine hydrobromide 0.3 mg intramuscularly, and if necessary, the drug should be reduced or replaced with a less reactive drug. The occurrence of choking in psychiatric patients is one of the common clinical emergencies 1. Because of the sudden occurrence, timely detection is the key, so the emphasis is on prevention. First aid must be timely and accurate, which is the key to successful resuscitation, clearing the airway blockage and keeping the airway open is the main task of resuscitation. 2, must strengthen the prevention of management, the usual work of nursing staff to grasp the patient’s condition, medication and adverse reactions, careful observation, especially mania, swallowing difficulties and other key populations to closely observe when eating, to be vigilant, to prevent food grabbing, overeating, not chewing and swallowing, to do the key populations in mind, focus on observation, special circumstances must be special care, to prevent choking occurs. 3, nursing staff skilled in first aid methods and steps for choking, once it happens, take timely and effective measures to avoid accidents and prevent choking from occurring.
