The posterior cul-de-sac is then entered with a spinal needle and the contents are aspirated with a syringe. With a positive test—
the presence of nonclotting blood
—a ruptured ectopic pregnancy may exist. If serous fluid is aspirated, the test is thought to be negative.
How is ectopic pregnancy diagnosed using Culdocentesis?
Culdocentesis is a procedure used to diagnose the presence of ruptured ectopic pregnancy by
evaluating for hemoperitoneum by inserting a needle and drawing back fluid from the pouch of Douglas
.
What is a positive Culdocentesis?
A positive tap is
one in which more than 2 mL of nonclotting blood is obtained
. Absolute volume may be related to the needle position or the rate of bleeding, so larger amounts of blood have no particular significance. Approximately 82-95% of ectopic pregnancies display nonclotting blood on culdocentesis.
Why is Culdocentesis done?
Culdocentesis is a procedure which
checks for abnormal fluid in the space that is just behind the vagina, the posterior cul-de-sac
. This procedure is done when pain occurs in the lower abdomen and pelvic regions, and other tests suggest that fluid may be present in the cul-de-sac.
What Culdocentesis means?
Definition. Culdocentesis is
a procedure that checks for abnormal fluid in the space just behind the vagina
. This area is called the cul-de-sac.
How does an ectopic pregnancy rupture?
An ectopic pregnancy occurs when a fertilized egg grows outside of the uterus. Almost all ectopic pregnancies—more than 90%—occur in a fallopian tube. As the pregnancy grows,
it can cause the tube to burst
(rupture). A rupture can cause major internal bleeding.
What are the complications of ectopic pregnancy?
Most ectopic pregnancies involve an embryo settling in a fallopian tube, but it can also happen in an ovary or the abdominal cavity. An ectopic pregnancy can be fatal for the pregnant person without prompt intervention. The fallopian tube, for example, may burst, leading to
shock and serious blood loss
.
What is the management of ectopic pregnancy?
The main treatment options are:
expectant management
– your condition is carefully monitored to see whether treatment is necessary. medication – a medicine called methotrexate is used to stop the pregnancy growing. surgery – surgery is used to remove the pregnancy, usually along with the affected fallopian tube.

Is salpingostomy and Salpingotomy the same?
Technically, the creation of a new tubal opening (os, after the Latin word for mouth) by surgery would be a salpingostomy, while
the incision into the tube to remove an ectopic is a salpingotomy
.
What is free fluid?
Free intraperitoneal fluid may be termed free fluid or (less correctly)
free intra-abdominal fluid
. It may be seen in small volumes in female patients, particularly around the time of menses and in some healthy young men. When free fluid is present in large amounts it is usually called ascites.
What is the cul-de-sac in the female body?
The Pouch of Douglas (cul-de-sac or rectovaginal septum) is
the space between the rectum and the uterus
. This is the lowest part of the abdominal cavity.
How many liters of blood can the abdominal cavity hide when internal bleeding occurs?
The abdominal cavity is highly distensible and may easily hold
greater than five liters
of blood, or more than the entire circulating blood volume for an average-sized individual.
What is the normal size of uterus?
The average uterus, which is also known as a woman’s womb, measures
3 to 4 inches by 2.5 inches
. It has the shape and dimensions of an upside-down pear. A variety of medical conditions can cause the uterus to increase in size, including pregnancy or uterine fibroids.
What is a reverted uterus?
A retroverted uterus means
the uterus is tipped backwards so that it aims towards the rectum instead of forward towards the belly
. Some women may experience symptoms including painful sex. In most cases, a retroverted uterus won’t cause any problems during pregnancy.
What does it mean to have fluid behind the uterus?
Menstrual blood that has refluxed through the fallopian tubes and fluids related to
ovulation
or ruptured cysts settle in it. Likewise, blood from a ruptured ectopic pregnancy, inflammatory debris from a pelvic or appendiceal infection and ascites due to malignancy, liver or cardiac failure may collect here.
