Final notes on fluid therapy
Crystalloids and colloids are the main fluids used during anesthesia but don’t forget to replace what is lost. So if a patient has lost a lot of protein or blood, then plasma, packed red blood cells, or whole blood should be administered.
Also remember that fluid therapy is not benign. Fluids should be thought of similarly to the way we think about drugs. That is, they are a tool that can be used – and abused – and abuse can lead to adverse effects. Excessive fluids create increased work for the heart and can cause edema. Fluids should be administered to meet, but not exceed, the patient’s needs. Also, specific fluids can have specific adverse effects. For example, plasma can cause an anaphylactic reaction, colloids can cause clotting dysfunction, etc.
Monitor fluid therapy by monitoring: 1) the total dose of fluids administered; 2) blood pressure changes in response to fluids; 3) packed cell and total protein; 4) presence of edema; 5) harsh lung sounds; 6) urine production (if possible); etc.

- Stabilize the patient prior to anesthesia.
- Turn down the vaporizer – may need to add analgesia.
