Antenatal checkups help gravida to give birth to healthy
baby. The aim of antenatal checkups is
to evaluate the health of woman and recognise any medical or surgical
condition that can have adverse effect on the outcome of
pregnancy.
In the first visit obstetrician not only confirms pregnancy but
also evaluates the woman by taking her personal, family history and appropriate
blood and urine examinations. General
health checkup includes total physical examination and recording height and
weight of the gravida. Common
investigations in the first visit are,
Blood examination: most importantly to know the hemoglobin
percent, blood grouping and Rh typing, also for any sexually transmitted
diseases, and serum hepatitis. In regions where hypothyroidism is endemic
thyroid hormone test is done. Few more
tests are done depending on the gravida’s medical history.
Urine examination: for any infection.
If the gravida is having Rh negative blood group, husband’s
blood grouping and Rh typing is done to take appropriate precautions if the
husband is Rh positive. If the gravida
is positive for any sexually transmitted diseases, spouse also evaluated for the
same and the couple treated to prevent any complications to the fetus.
First visit: confirmation of pregnancy, height and weight,
blood pressure recording, blood and urine examination, if necessary ultrasound
scanning.
In developed countries Pap smear test is done as a screening
procedure for cancer cervix.
In consecutive visits and every visit
Weight, blood pressure, fetal growth (height of uterus) is
noted. Any complaints by the gravida are
addressed to. The total weight gain in
pregnancy in a normal healthy woman, with a healthy pregnancy is 10-12 Kg. Increase in weight by 1/2 Kg a week after
16 weeks of pregnancy is expected.
Underweight woman is encouraged to gain more weight and obese to
restrict total pregnancy weight gain to 6-8 Kg only.
Blood test for hemoglobin percent and urine for any sugar
and proteins is done.
If family history of diabetes mellitus is present the
gravida needs to undergo test for blood sugar at 20 weeks, 28 weeks and
repeated at appropriate intervals if necessary.
Rh negative group woman with Rh positive husband will have
to undergo blood test (Coomb’s test) at 20 weeks, 28 weeks and 36 weeks to note
any changes in the blood that may adversely affect the fetus.
Woman with hypothyroidism may have to undergo repeat test
for thyroid evaluation for adjusting the dose of thyroxin hormone.
Ultrasound scanning is done early in pregnancy to confirm
viable pregnancy and for dating, between 12-14th week and around 18 - 22 weeks to rule out any fetal anomalies.
Scanning may be repeated if there are any problems affecting the growth
of the fetus and evaluation of fetal growth.
Any illnesses occurring during the pregnancy will need
appropriate tests.
In India
gravida is given all the reports of investigations. She has to carry all these when she visits
the obstetrician. If the clinic or
hospital gives a record of all the investigations with the history and
examination of woman she should carry this to her consultant at every visit to
record findings. This will help in early
identification of any risk arising during the course of pregnancy.
Good antenatal care will ensure healthy mother and healthy
baby.
