From Wikipedia, the free encyclopedia
A paracervical block is an
anesthetic procedure used in
obstetrics and gynecology , in which a
local anesthetic is injected into between two and six sites at a depth of 3–7 mm alongside the
vaginal portion of the cervix in the
vaginal fornices .
[1] In the United States, the paracervical block is underutilized during insertion of
intrauterine devices (IUDs). There is speculation that this is related to the disproportionate under-researching of women's health.
[2]
It is used for various obstetric and gynecologic procedures, such as
hysteroscopy and
vacuum aspiration .
It is as efficient as
intracervical block , according to a study on women undergoing
vacuum aspiration with
lidocaine as anesthetic agent.
[3]
The majority of surgical abortions in the united stares are performed with a paracervical block with or without the addition of other pain medications. The best specific technique has yet to be defined and there is still a lot of procedure related pain.
[4] The choice of the best anesthesia depends on patient preference and resources available.
[4]
In addition, a paracervica block may be permormed by a wide variety of clinications including familiy medicine practitionor, advanced practitionors and RN's.
[5]
Addition of
ketorolac may offer added benefit of improved pain control.
