With morphine, the elderly should pay attention
Morphine is a strong central inhibitor, has sedative, analgesic, inhibits the contraction of respiratory and smooth muscle, and is a commonly used drug for the elderly.
If morphine is taken together with other antidote, it can treat severe pain caused by severe pain or visceral disease in patients with myocardial infarction. It also has good effects on cardiogenic pain, especially for acute pain that is not effective in other analgesics.Severe fractures, trauma, burns, etc., have excellent curative effect.
But can not be scrupulous, the elderly should take the following points when taking morphine: (1) When taking morphine, you should pay attention to observe the inhibition of breathing and cardiovascular, do not use too much, otherwise it may cause acute poisoning, such as patientsComa, inhibition of breathing depth, dilated pupils, decreased blood pressure, etc.
In the event of acute poisoning, oxygen should be taken immediately, artificial respiration, and respiratory stimulants should be injected.
For the elderly and infirm, it should be reduced.
(B) morphine has a good effect in the treatment of cardiogenic asthma.
Cardiac hypertension is due to left heart failure, acute pulmonary edema, mental stress, restlessness, shortness of breath, etc.
Intramuscular injection of small doses (5-10mg) of morphine can slightly inhibit the respiratory center, so that the breathing is converted from fast and shallow to slow and deep, alleviating the patient’s dyspnea syndrome.
However, if cardiogenic hypertension is accompanied by coma, shock, excessive sputum and severe lung disease, morphine should be added.
(3) Patients with geriatric hyperplasia (hypertrophy), Addison’s disease, urethral stricture, etc., should be used with caution or morphine.
Morphine can increase the pressure of cerebrospinal fluid, so the intracranial pressure is increased, the tumor in the brain, the brain injury, and the elderly with severe liver dysfunction should also avoid morphine.
(4) Old people with bronchial asthma cannot use morphine.
This is because it not only relieves bronchoconstriction, but also exacerbates muscle contraction, induces spasms, and inhibits the respiratory center, making breathing more difficult and leading to respiratory failure.
(5) Pain caused by cholecystitis can not be treated with morphine analgesia.
Because morphine can contract the biliary smooth muscle, Oddi’s sphincter contraction, and the pressure in the gallbladder and biliary tract increases, causing the disease to worsen.
Morphine has constipation, nausea, vomiting, dizziness, sweating, urgency or dysuria, etc., should be closely observed when using the drug.
(6) The combination of morphine and barbiturate (sedative sleeping pills) can enhance the analgesic effect of morphine and significantly enhance central inhibition.
Therefore, when combined, it should be reduced according to the condition of the disease, otherwise, accidents can occur.
(7) morphine avoidance combined with succinylcholine, so as not to strengthen the vagus nerve excitability, thereby aggravating morphine-induced bradycardia, and even transient sinus arrest.
Similarly, excessive irritability in drinking, avoid morphine sedation, so as not to cause severe central nervous system depression and respiratory depression, otherwise it may cause life-threatening.
(8) Can be used in morphine poisoning, caffeine.
Corramin has an antagonistic effect; caffeine acts as an antidote to morphine poisoning.
