WARNING!
Intrauterine distension
Intrauterine distension is usually possible with pressure values between 35 to
75 mmHg. A pressure above 75 mmHg is required only in rare cases or if the pa-
tient has an excessively high blood pressure.
WARNING!
Fluid overload
There is a risk of irrigation fluid reaching the circulatory system of the patient's soft
tissue by passing through the uterus. This can be affected by distention pressure,
flow rate, perforation of the uterine cavity and duration of the hysteroscopic sur-
gery. It is critical to closely monitor the input and outflow of the distending liquid
at all times.
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 [} 52]). 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!
Containers and fluid bags
Make sure the containers and fluid bags hang freely, are not resting on something,
and do not touch other objects. Failure to follow these instructions means the defi-
cit cannot be calculated correctly.
WARNING!
Containers and fluid bags
Make sure the containers and fluid bags hang freely, are not resting on something,
and do not touch other objects except the bag deflectors. Failure to follow these in-
structions means the deficit cannot be calculated correctly.
WARNING!
Accuracy of the deficit
To avoid affecting the accuracy of the deficit calculation ensure that the first step
of the container change is to disconnect tubing from the full containers. Reconnect
tubing to the new containers only if they are already inserted into the scale.
