WARNING!
Fluid deficit
The fluid left in the patient must be monitored. The deficit is the total amount of
fluid left in the patient or unaccounted for otherwise. Take notice of the measure-
ment tolerance of the system (see Chapter Technical Data [} 49]). Estimating the
fluid volume remaining in the patient is the physician's responsibility.
WARNING!
Fluid intake and output surveillance
Strict fluid intake and output surveillance should be maintained due to the risk of
fluid overload. For healthy patients, the maximum fluid deficit of 1,000 ml is sug-
gested when using a hypotonic solution (e.g. glycine, sorbitol and mannitol). If iso-
tonic solutions (e.g. saline, Lactated Ringer's) are used, the fluid deficit should not
exceed 2,500 ml.
WARNING!
Serum sodium concentration
It is also necessary to monitor the concentration of sodium in the blood of the pa-
tient to prevent electrolyte disturbances. Monitoring of the concentration of so-
dium in the blood must be performed by the physician and is not performed or sup-
ported by the system.
WARNING!
Loss of deficit and inflow value
The deficit display value is lost in case of a power loss or "brownout."
WARNING!
Failure of scale connection
If the message "Check Scale Connection" appears, the deficit must be calculated
manually. The pump keeps displaying the last known deficit value determined prior
to the failure of the scale connection.
WARNING!
Container change during surgery
A container change during surgery is only allowed, if the container holds at least
0,5 liters of fluid. Otherwise, the deficit value may be falsified. In this case, the
manufacturer recommends manual deficit calculation.
WARNING!
Hyponatremia
Some distension fluids may lead to fluid overload and, consequently, hyponatremia
with its attending sequelae. This can be affected by the distending pressure, flow
rate, and duration of hysteroscopic procedure. It is critical to closely monitor the in-
put and outflow of the distending liquid at all times.
WARNING!
Pulmonary edema
Hysteroscopic surgery is associated with a risk of developing pulmonary edema res-
ulting from fluid overload with isotonic fluids. It is critical to closely monitor the in-
put and outflow of the distending liquid at all times.
