Fluid and electrolyte balance in and out always equal in surgical patients?

In brief: No

Fluid & electrolyte balance in the peri-operative time period is highly variable.
It depends on a person's medical conditions before surgery such as heart failure or kidney disease. It depends on medications used before surgery. It depends if the surgery was long, complicated, emergency, or due to sepsis. Fluid retention & electrolyte imbalance early after major surgery is common & correctable.

In a perfect state, the "In's should equal the "Out's". The problem is that we cannot measure all the "outs" (sweat, respiratory water loss, fluid losses from tissue during major surgery), therefore the I's should be higher.
