Description and Purpose
Culdocentesis is a procedure where fluid
is withdrawn from the pelvic cavity in order to be examined for abnormalities
such as blood or infectious agents. The main reasons for performing this
- To identify the cause of (PID).
- To diagnose .
Preparation and Procedure
The same position as for a pelvic exam is adopted. The doctor inserts
a needle through the vagina and into the cul-de-sac
of Douglas , an area just behind the uterus that is defined by the
membrane lining the abdomen and pelvic organs, and withdraws a sample
of fluid from this cavity.
The fluid removed is then examined. If the fluid contains nonclotting
blood, a ruptured ectopic pregnancy may be suspected. If PID is suspected,
the fluid may be examined for infectious agents. The whole procedure takes
about 10 minutes.
