Elderly people with hypotension should pay attention to the following points: 1. Asymptomatic hypotension does not require treatment because there is no significant reduction in cerebral blood flow, but patients should be encouraged to get up and walk, avoid long-term bed rest or sedentary, should correct medical diseases, take measures to increase blood volume, improve blood circulation and enhance heart function, already dehydrated should not use diuretics, should develop good bowel habits to avoid excessive force during defecation. 2.Change position and posture slowly. Avoid getting up suddenly or changing position quickly, and rest for 2 to 3 min at each change of position to adapt the postural compensatory response to each change of position. Before getting up to stand or start walking in the morning, first sit on the bed for a few minutes. When going to the bathroom toilet, falls due to postural hypotension resulting in confusion or loss of consciousness can lead to fractures and other injuries, and using a bedside potty or urinal can prevent accidents. 3.Avoid excessive satiety, eat less and more meals, eat less large amounts of easily digestible carbohydrates, take in sodium and salt appropriately, drink the right amount of water to maintain normal blood volume. 4, bath water temperature should not be too high, bath time should not be too long. 5.Reduce going out in the heat to reduce sweating. 6.Wear elastic long socks to increase the amount of blood returned to the heart. 7.Try to avoid drugs that are not essential to affect blood pressure. General measures (1) for several situations prone to postural hypotension to take: ① sleep using the head high feet low, with the ground plane is more than 20 ° slope of the bed board, in order to reduce the renal artery pressure, conducive to the release of renin and the increase in the amount of effective blood circulation. ②Use a bedside commode for nighttime urination to prevent postural hypotension during nighttime toileting; toilets should be equipped with handrails for ready support; keep the bowels open and do not exert excessive force during stooling. (③) Position change should not be too fast, such as from lying to sitting up, upright and walking, etc. Each position is best maintained for 1 to 2 min, after observation of no symptoms, no hypotension, before entering the next position. ④ Bathroom should be paved with rubber mats, bath water should not be too hot, bath time should not be too long. ⑤ Meals should be increased appropriately, each meal should not be too full, and standing should not be done immediately after the meal. ⑥Avoid overhead or other dangerous work. ⑦ Avoid prolonged bed rest, prolonged standing and excessive exercise, and use enemas sparingly. For those who must be bedridden for a long time, it is advisable to strengthen the active activities of the lower limbs or passive massage to improve their blood circulation. (8) Once the precursor symptoms of syncope appear, the patient should lie down on the ground as soon as possible, and medical personnel should quickly take appropriate rescue measures. (2) rehabilitation exercises should be gradual: this is especially important in the elderly and frail, bedridden and suffering from cardiovascular disease. The change of position should not be too rapid and violent, and should be assisted by others or equipment first, then gradually transition to independent standing and walking, and the content and time of exercise should also be gradually increased. (3) Physical therapy: such as using tight lap band, tight pants and elastic stockings that can increase venous return, but some elderly people do not want to accept them. Etiological treatment (1) Avoid all kinds of triggering factors, especially be careful with drugs that can easily cause postural hypotension (see above); those who are using drugs that are clearly identified as having caused postural hypotension should stop using them decisively; drugs that must be used, such as nitroglycerin preparations used for angina pectoris, should be promptly reduced or the interval between doses should be lengthened or the dosage form should be changed or Change to other drugs. (2) Appropriate relaxation of water and sodium intake restrictions. (3) Promptly treat heart failure, arrhythmias, other cardiovascular diseases, dehydration, electrolyte disorders, anemia, diabetes mellitus, neurological diseases, and endocrine system diseases that may cause hypotension and syncope. A permanent atrioventricular sequential pacemaker is recommended for those with severe morbid sinus node syndrome or high atrioventricular block that repeatedly causes syncope. For those with few syncopes and not closely related to arrhythmias, do not use antiarrhythmic drugs prophylactically as much as possible, because these drugs have arrhythmogenic effects; they may aggravate existing heart failure or arrhythmias; they also have other side effects and may cause patients to become resistant to them over time. In patients with EPS-induced monomorphic sustained ventricular tachycardia, positive LP, and spontaneous ventricular tachycardia recorded by Holter, the primary disease should be treated aggressively and antiarrhythmic therapy should be given at the same time. Drug therapy Generally, drug therapy should not be used too aggressively, but should be tried under close observation only when the symptoms are severe, syncope attacks are frequent, and the above methods are ineffective. (1) Increase blood volume: It is suitable for those who usually have very low salt and no absolute contraindication. The intake of sodium chloride or oral hydrocortisone acetate 0.05-0.1mg/d can be increased, which has the effect of raising the standing blood pressure, but it should be monitored for side effects such as heart failure and electrolyte disturbance. (2) elevated blood pressure: such as vasopressors and sympathomimetic drugs ephedrine, mephedrone, etc., have been tried in small doses under inpatient conditions, the effect of elevated blood pressure is positive, but its side effects on the heart – cerebrovascular limit its application. (3) β-blockers, vagus nerve inhibitors: such as metoprolol 12.5-25mg/d or scopolamine (654-2) 10mg/d can better inhibit the occurrence of syncope, but the sensitivity of the elderly to these two drugs vary, it is best to try half a dose first, no adverse reactions before using the full amount under close observation. Before using the drug must be strictly grasp the indications and contraindications. (4) Other: indomethacin (anti-inflammatory pain), ergometrine preparations also have some efficacy, but in elderly patients should be used with caution.
