My answer: according to your description, the patient’s condition is quite complex and serious, there is always the possibility of acute heart failure, renal failure, recurrent infarction and other conditions, so that the patient’s resuscitation will be very difficult. Want to determine whether it is stomach pain or pain caused by hepatomegaly, generally can be judged by palpation, subxiphoid pressure pain is obvious is generally stomach pain, in this case should pay attention to the existence of stress ulcers, or antiplatelet drugs, anticoagulants, the use of the gastric mucosal damage is heavier, to avoid gastrointestinal bleeding, aggravate the condition; if the subxiphoid pressure pain is not obvious, and at the same time there is a liver enlargement, hepatic area percussion pain and other physical signs, generally for the caused by hepatomegaly, which can be determined by bedside ultrasound, and is usually caused by right heart failure leading to impaired body circulation. Basic treatment for this group of patients should have been included as long as they are hospitalized. Typically the treatment consists of sedation (including analgesia – morphine), oxygen, cardiotonic (digitalis or cediran), diuretic (tachycardia, spironolactone, etc.), vasodilator (sodium nitroprusside, nitrates, etc.), and possibly aminophylline, or even dexamethasone, etc., which are based on a foundation of basic treatments that are still very difficult to alleviate, and the presence of More severe renal failure, at present, the creatinine is about 300, which is not very high, but it is not ruled out that after the gradual increase, there is severe renal failure or even uremia, in which case hemofiltration treatment can be considered, but it is usually carried out in the ICU care unit. At present, the patient needs to be clear that the condition is very serious and complex, do not rule out that at any time there is an aggravation of the condition, life-threatening situation, the family should be extremely cooperative with the doctor’s treatment, to provide all the facilities, the hospital and the family should work together, and try to save the patient’s life as the first priority.
