Surgery Definition - What steps to considered in prescribing fluid to surgical patient?
The steps include correcting any pre existing deficit. The pre existing deficit can be detected via history of diarrhoea, vomiting and thirst, physical examination which may reveal sunken eyes, tachycardia, oliguria, decreased in skin turgor and dry mucous membrane. Investigation may reveal high hematocrit, increase in urea with concentrated urine of more than 650 Osm.
The next step include the administration of the maintenance fluid for daily requirement. The amount of maintenance fluid needed in 24 hours can be estimated by considering the following formula. 100 ml/kg for the first 10 kg, 50ml/kg for the next 10 kg, 20 ml / kg for every kg over 20 kg. As an example for human weigh 70 kg the amount of maintenance fluid requirement may inlcude 100 x 10 =1000 + (50 x10)=500 + (20x5) =1000. Total maintenance fluid requirement may include 1000 + 500 +1000 = 2500 ml/day.
The next step is to considered the replacement of any abnormal ongoing losses.
