PREGNANCY
INTRODUCTION
For
pregnancy and labour to be achieved with minimal difficulty, a woman must have
normal reproductive anatomy. When
structural abnormality of the pelvic organs exists, problems arise which can
place an extra burden on mother and fetus.
Dystocia may result from malformations and displacement.
DEFINITION
Uterine
malformations is defined as the malformations and displacement of the body of
uterus caused by the persistence to a greater or lesser extend of the septum
between the mullarian duct.
TYPES OF
UTERINE MALFORMATIONS
They are:-
1.
Arcuate
Uterus
2.
Uterus
didelphys
3.
Uterus
bicornis
4.
Uterus
unicornis
5.
DES
– Related abnormality
1) Arcuate Uterus
The
corneal part of the uterus remains separated.
The uterine fundus looks concave with heart shaped cavity outline.
2) Uterus didelphys
There
is a complete look of fusion of the mullarian ducts with a double uterus,
double cervix and a double vagina.
3) Uterus bicornis
This
is of varying degree of fusion of the muscle walls of the two ducts.
1.
Uterus bicornis
bicollis
There are 2 uterine
cavities with double cervix with or without vaginal septum.
2.
Uterine bicornis
unicollis
There are 2 uterine
cavities with one cervix. The horns may
be equal or one horn may be rudimentary and have no communication with
development horn.
3.
Septate Uterus
The two mullarian
ducts fused together but there is persistence of septum in between the two
either partially (sub-septable) or completely.
6.
Uterus unicornis
Failure of development
of one mullarian ducts
7.
DES – Related
abnormality
If it is due to DES
exposure during intrauterine life varieties of malformations are included.
Eg: Hypoplasia Uterus
‘T’ shaped uterus and cervical hypoplasia.
CLINICAL
FEATURES
They are classified into gynaecological
and obstetrical.
1.
Gynaecological
1.
Infertility
and dyspareunia.
2.
Dysmenorrhoea.
3.
Menorrhagia
2. Obstetrical
1.
Mid
trimester abortion
2.
Cornual
pregnancy with inevitable rupture around 16th week.
3.
Increased
incidence of malpresentation
4.
Preterm
labour
5.
Prolonged
labour
6.
Obstructed
labour
7.
Retained
placenta and PPH.
Effect of Uterine Malformations on Pregnancy
If
their insufficient hypertrophy the possible difficulties are
·
Abortion
·
Pre-mature
labour
·
Abnormal
lie of the fetus
·
In
labour there will be poor uterine function may be experienced.
·
Occasionally
problems arise when a fetus is
accommodated in one horn of this double uterus and the empty of the horn has
filled the pelvic cavity.
Diagnostic
Evaluation
1.
Internal
Examination reveals separate vagina and two cervix.
2.
Hysterography
3.
Hysteroscopy
4.
Ultrasonography
5.
MRI
6.
Laproscopy
MANAGEMENT
a) Surgical Management
1.
Strassman
Utriculoplasty Operation
2.
Jonis
Wedge Metroplasty
3.
Tomkins
operation
4.
Hysteroscopic
Ressection
NUSRING MANAGEMENT
·
The
nurse should give psychological support to the patient.
·
Send
the blood and urine for routine examination.
·
Check
the vital signs every 4th hrly.
·
Assess
for any systemic diseases such as DM, HTN, TB etc.
·
Obtain
consent for operation.
·
Mother
should be kept nil by mouth.
·
Pre-operative
medication should be given such as Inj-TT.
·
Prophylactic
antibiotics such as cephalosporins to reduce the risk of infection.
·
Preparation
of the part should be done with antiseptic solutions.
POST-OPERATIVE CARE
·
Provide comfortable
position i.e., supine position.
·
Give foot end elevation.
·
Monitor the vital signs.
·
Observe
the patient for any signs of infection.
·
Assess
the incision site for bleeding.
·
Maintain
aseptic techniques in all procedure.
·
Administer
antibiotics to prevent the infection.
·
Administer
analgesics to relieve pain.
·
Change
the soiled dressings at least twice a day.
·
Provide
calm and quit environment.
CONCLUSION
Malformations
can cause dystocia. Malformations may be
congenital or may be acquired. This can
be managed by surgical intervention.
