REVISED EXPECTED DATE OF DELIVERY – 11th of August 2010 – by early dating scan at 18 weeks
GRAVIDA - 2
PARA - 1
GESTATION – 38 weeks + 6 days
1. MENSTRUAL HISTORY
She attained menarche at the age of 12 years old with regular cycle of 28-30 days interval lasting for 5-7 days of bleeding. The amount was about 2-3 pads fully-soaked. No clots. No dysmenorrhea. After her first pregnancy, at the age of 21, her menses started to become irregular until now, associated with dysmenorrhea.
2. PRESENTING COMPAINT(S)
Madam RNI, 35 year-old Malay, gravida 2 para 1 at 38 weeks + 6 days period of gestation was admitted to Hospital Sungai Buloh for elective lower segment caesarean section due to macrosomic fetus.
3. HISTORY OF PRESENTING COMPLAINT
Yesterday, on the 1st of August 2010, the patient came to Hospital Sungai Buloh after being scheduled for elective lower segment caesarean section today, 2nd of August 2010, in the afternoon.
At 21 weeks period of gestation during her booking, she was diagnosed to have gestational diabetes mellitus after being tested for modified glucose
2
tolerance test. She was only advised to control her diet and was not prescribed on any medications.
However, a transabdominal ultrasound done at 28 weeks period of gestation revealed macrosomic baby with estimated fetal weight of 3.2kg. Unfortunately, she was not referred to Sungai Buloh Hospital until four days ago after a significant increase of estimated fetal weight to 4.2kg based on the transabdominal ultrasound scan during her follow-up. After physical examination and transabdominal ultrasound scan was done in the hospital, she was indicated for elective lower segment caesarean section and was given the date which is on the 2nd August 2010.
Yesterday, she came to the PAC Sungai Buloh Hospital at 9am. There were no signs of labour like painful uterine contractions, leaking liquor, or ‘show’. Fetal movement was good and the CTG was reactive. A transabdominal ultrasound was done at the PAC and the estimated fetal weight was 4.2kg.
4. ANTENATAL HISTORY
Madam RNI was apparently well until 21 weeks period of gestation, when she was diagnosed of having gestational diabetes mellitus. This is her second pregnancy after 15 years of no pregnancy. She is currently at 38 weeks and 6 days of gestation. This pregnancy is unexpected but wanted. She had a period of amenorrhea for four months but she did not expect for getting pregnant because of certain reasons, 1) she had been having irregular menstruation after her first child, and 2) she is obese and she only thought of having gained weight. She only suspected that she was pregnant after she experienced some episodes of mild pain on her breasts associated with some discharge on exertion. She also noticed some fetal movements which is the quickening at the same point of time. She had history of constipation. She did not have any history of morning sickness.
She did a self urine pregnancy test brought from the pharmacy and it came out positive. Subsequently, she went to a private clinic to reconfirm and the result was consistent. Early dating ultrasound scan was also done and confirmed her pregnancy at 18 weeks period of gestation. Revised expected date of delivery is on the 11th September 2010. There were no fetal abnormalities detected.
At 21 weeks period of gestation, she went to Klinik Komuniti Shah Alam for booking. Routine examination and screening was done. All were all within normal range and non-reactive, respectively. Ultrasound was done and her REDD was consistent.
Apart from doing the routine examination, Madam RNI was also screened for Gestational Diabetes Mellitus by testing the modified glucose tolerance test because she has first-degree-relative history of diabetes mellitus and she is 35
years old. Results were as follows:
Fasting 5.2 mmol/L
2-hour postpandrial 8.6 mmol/L
3
She was diagnosed of having gestational diabetes mellitus and was advised on diet control. No hypoglycaemic medications were prescribed. Her blood sugar profile was controlled throughout the pregnancy. Her latest blood sugar profile (BSP) on admission was normal;
Fasting 4.2 mmol/L
2-hour postpandrial 4.9 mmol/L
Post lunch 5.1 mmol/L
Post dinner 3.9 mmol/L
Despite her controlled blood sugar profile, a transabdominal ultrasound done at 28 weeks period of gestation revealed macrosomic baby with estimated fetal weight of 3.2kg. Unfortunately, she was not referred to Sungai Buloh Hospital until four days ago after a significant increase of estimated fetal weight to 4.2kg based on the transabdominal ultrasound scan during her follow-up. After physical examination and transabdominal ultrasound scan was done in the hospital, she was indicated for elective lower segment caesarean section and was given the date which is on the 2nd August 2010. Her weight during the examination was 94kg. She experienced backaches and noticed increased frequency in urination.
5. PAST OBSTETRIC HISTORY
This is her second pregnancy. She has 1 teenage daughter aged 15 years old who was delivered by full term spontaneous vaginal delivery with no abnormal labor or instrumentation, weighing of 3.5kg. She breastfed her daughter for two whole years. Her daughter is now alive and well.
6. CONTRACEPTIVE HISTORY
She denied usage of any contraceptive pills or other method.
7. PAST GYNAECOLOGICAL HISTORY
She had a history of subfertility after her first child was born. She was obese at that time weighing of 98kg but was not associated with hirsutism. She went to Klang Hospital to check about her subfertility problem. Ultrasound scan was done and revealed no significant abnormalities. She was told to have hormonal imbalance and was advised to reduce her body weight.

16.SUMMARY
Madam RNI, 35 year-old Malay, gravida 2 para 1 at 38 weeks + 6 days period of gestation was admitted to Hospital Sungai Buloh and scheduled for elective lower segment caesarean section for delivery of macrosomic fetus due to gestational diabetes mellitus
17.DIAGNOSIS
14.1 Provisional Diagnosis
Gestational Diabetes Mellitus
Points to support: The modified glucose tolerance test revealed 2-hour postprandial glucose level of 8.6mmol/L. Since the glucose intolerance was first discovered at 21 weeks period of gestation, and the patient was previously non-diabetic.
14.2 Differential Diagnosis
Previously undiagnosed Pregestational Diabetes Mellitus
Points against: No overt diabetes was known previously. If the glucose intolerance disappeared after the delivery without requiring any medications, hence pregestational diabetes mellitus is ruled out

Distended abdomen, size of 40 weeks
gravid uterus
Linea nigra
Striae gravidarum
Hyperpigmented areolar

1. Full Blood Count on 2 nd of August
Event Result Status
WBC 13.63 (4.0 – 11.0 x 109/L)
Abnormal
RBC 4.14 (4.5 – 6.5 x 109/L) Normal
Hemoglobin 10.4 (12.0-15.0 g/dl) Abnormal

Interpretation:
White blood cell count was elevated post-operation probably in response to medication.
Hemoglobin, hematocrit and MCV were reduced and red cell distribution width was raised- probably due to the blood loss during the operation and uterine atony causing postpartum hemorrhage.
19.PROGRESS DURING HOSPITALIZATION
DAY 1 post operation (2 nd August 2010)
The operation was uneventful. Baby boy with birth weight of 4.88kg was delivered at 1640H, with Apgar score 9 in 1 min and 10 in 10 mins. Estimated blood loss was 500ml. Liquor was clear.
After the operation, she has been keeping well,
BP – 108/70mmHg
Pulse Rate – 71/min, regular
spO2 – 100%
She was pale but alert, complaining of nausea, no vomiting, no shortness of breath or palpitation. She was on strict pad chart. Since the operation, she has been using 3 pads full-soaked
On abdomen examination, the uterus was not well-contracted at 22-week size of a gravid uterus
She given IV oxytocin 40 units over 6 hours
DAY 3 post operation (4 th August 2010)
Uterus was soft, non-tender, well-contracted at 20 weeks size of a gravid uterus, no active bleeding at the site of operation. No longer has per vaginal bleeding.
She was due for discharge and was told to repeat modified glucose tolerance test 6 weeks later.
20.DISCUSSIONS
Madam RNI has a firfamily history of DM so she was indicated for Modified Glucose Tolerance Test (MGTT) as she was considered as a high risk groups.
There are other indications for MGTT which are;
1. Two or more episodes of glycosuria on routine testing
2. Diabetes in a 1st degree relative
12
3. Maternal weight greater than 85 kg
4. Maternal age greater than 30 yrs old
5. Previous hx of Gestational Diabetes Mellitus
6. Previous baby of 4.0 kg or more (macrosomia)
7. Previous unexplained perinatal death
8. Previous congenital anomelies
9. Polyhydramnions
10. Women from an ethnic group with a high prevalence of type II DM (Hispanic, Native American, African-American)
Definition of Gestational Diabetes Mellitus
The WHO has defined Diabetes Mellitus as either a raised fasting blood glucose level of > 7.8 mmol/L or a level of > 11.0 mmol/L 2 hours following a 75 g oral glucose load.
Pathogenesis of Gestational Diabetes Mellitus
Placenta secretes anti-insulin substances; such as human placental lactogen (HPL), hCG, estriol, cortisol and progesterone
Presence of these substances in the maternal blood
Glucose intolerance develops in the mother; mainly if maternal β cells are unable to produce additional insulin which is required to counteract this antagonism
Maternal Gestational Diabetes Mellitus
Maternal nutrients mainly glucose can readily crosses placenta but not maternal insulin
As the mother develops hyperglycemia due to Gestational Diabetes Mellitus hence fetal pancreas will secrete additional insulin to cope with the fetal hyperglycemia
13
Fetal β cells hyperplasia
Fetal hyperinsulinemia
Effects of Fetal Hyperinsulinemia
1. Reduced lung surfactant RDS
2. Increased erythropoiesis can leads to jaundice or hyperviscosity syndrome. Hyperviscosity syndrome will later develops into necrotizing colitis or renal vein thrombosis.
3. Increased fetal metabolism which will increases O2 demand. Low O2 supply from the mother can leads to intrauterine death.
4. Macrosomia shoulder dystocia
5. Hypoglycemia
6. Hypertrophic myocardiopathy
Effects of Diabetes on Pregnancy
1. Increased miscarriage rate
2. Increased perinatal loss due to intrauterine death (IUD)
3. Macrosomic baby hence is at risk of dystocia
4. Fetal lung maturation may be delayed; if the fetus was delivered prematurely then the risk of getting RDS is increased
5. Risk of pre eclampsia
6. Risk of polyhydramnions
7. Susceptible to infections; mainly UTI and candida vaginitis
Management of Diabetes
A. Pre pregnancy
The women who are known to be diabetic and women who have had gestational diabetes should seek medical attention before they get pregnant. This consultation offers opportunities in explaining to them about;
1. The reason for meticulously maintaining her blood glucose at normal level before conception
2. The need of taking folic acid to reduce the risk of neural tube defects
14
This consultation can also be used as an assessment for the presence of any Cx related to diabetes, such as diabetic retinopathy and nephropathy.
Women who are on oral hypoglycemic drugs should preferably be changed to insulin therapy.
We should check for her glycosylated Hemoglobin, HbA1c that reflects her glucose control over the previous 10 weeks. High levels of HbA1c are associated with an increased rate of fetal abnormality.
B. Pregnancy
Euglycemic state should be maintained; with fasting glucose less than 5.3 mmol/L and 2 hour post prandial blood glucose should be less than 6.7 mmol/L.
Blood sugar profile should be checked before or after each meal; preprandial or postprandial glucose level and the result should be less than 6 mmol/L or 6.7 mmol/L, respectively.
Normal blood glucose level should be maintained with a mixture of short and medium-acting insulin.
But Mrs Frh was prescribed with Monotard (long acting) 6 unit that has to be taken once daily, at 2240 H.
Ultrasound scan that was done during the first 12 weeks of pregnancy provides accurate estimation of the period of gestation. Meanwhile, scanning between 18 – 20 weeks of gestation allows exclusion of any major malformations and around 34 weeks of gestation, it permits assessment of fetal growth.
Regular assessment of fetal growth and wellbeing should be performed.
Timing of Delivery
Delivery at up to 40 weeks of gestation is possible if the sugar control is good. But if there is inadequate blood glucose control, or the presence of polyhydramnions, fetal macrosomia or maternal obesity delivery at 38 weeks of gestation is indicated. Delivery at earlier than 38 weeks is not really indicated to prevent Respiratory Distress Syndrome in the premature baby.
Management of Labour
The intention is to achieve vaginal delivery. Labour can be induced by doses of oxytocin. An artificial rupture of membrane (ARM) should be performed. Blood glucose level needs to be monitored at frequent intervals; mostly done at 2 hourly. The fetus should be monitored throughout labour and during vaginal delivery shoulder dystocia should be anticipated. On the other hand, a caesarean section may be performed if there is significant petal macrosomia or poor fetal status (CTG), or if labour fails to progress satisfactorily. Uncomplicated diabetes is not an indication for operative delivery.
Follow Up of Women Who Have Had Gestational Diabetes Mellitus
15
Follow up is important as up to 50% of women with Gestational Diabetes Mellitus may develop overt diabetes; mainly Type II.
At the follow up visits, we should encourage her to follow a diet which is appropriate for a diabetic. She should also be advised to take these following measures;
1. Avoid becoming obese
2. Take regular exercises
3. Avoid cigarette smoking
4. checked annually for hypertension
These women have a 50% chance of developing Gestational Diabetes Mellitus in the future pregnancy. If she intend to become pregnant again, testing for hyperglycemia before conception or in early pregnancy is recommended.
