rehydration test

The fluid replacement test is an auxiliary test method for checking whether the urination function is normal. Oliguria means that the amount of urine per adult is less than 400ml per 24h, and that of urine is less than 100ml per 24h, or no urine at 12h. If oliguria or anuria occurs, if it is not treated properly, it will eventually lead to acute renal failure. The causes of oliguria and anuria are prerenal, renal and post-renal. Prerenal is mainly caused by various factors such as shock, dehydration, blood loss, heart failure and other factors, resulting in effective circulating blood loss, blood pressure drop, affecting renal blood flow and glomerular filtration rate. Renality is mainly caused by kidney disease caused by renal ischemia and renal poisoning. Dehydration is due to insufficient intake or excessive discharge, resulting in uterine oliguria, which is pre-renal. After supplementing the effective blood volume, observing changes in urine volume can help identify the cause of oliguria. Basic Information Specialist classification: growth and development check classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Tips: Inappropriate people: acute cardiac insufficiency, or cirrhosis ascites and other critical illness, uremia. Normal value The urine volume is 20ml~30ml per hour. Clinical significance Abnormal results: 1. If the urine volume is >30ml per hour, it can be considered as insufficient blood volume. For the indication of fluid expansion, the infusion volume should be increased. 2. The urine volume is 20ml per hour, which can be considered as acute renal failure and oliguria. The infusion volume should be strictly controlled, and other treatment measures should be taken. The people who need to be examined: the cause of oliguria and anuria. High results may be diseases: precautions for renal diabetes insipidus Taboo before check: Maintain normal sleep and diet. Requirements for examination: Close observation of changes in the condition, if heart failure or heart failure worsens during rehydration, immediately stop rehydration and apply diuretics. Inspection process 1. Intravenously drip with 500 ml of 5% glucose saline and drip in 30 min. 2. Urine was collected every 60 minutes after rehydration and urine volume was measured for 2 hours. Not suitable for the crowd There are no special taboos. Adverse reactions and risks No related complications or hazards.
