OG12.1-11,OG16.4 | Medical Disorders in Pregnancy — Assignment
CLINICAL SCENARIO
You are the senior house officer on the antenatal ward. Mrs Priya R., a 29-year-old primigravida at 28 weeks of gestation, presents for a routine antenatal visit. She has been known to have moderate iron-deficiency anaemia (Hb 8.4 g/dL at 20 weeks), was recently diagnosed with gestational diabetes mellitus (GDM) by the DIPSI protocol, and her current blood pressure today is 148/96 mmHg with 1+ proteinuria — a new finding. Fundal height measures 24 cm (less than expected for dates). Write a structured management plan for this patient that integrates the diagnosis, investigation, and management of each complicating condition, addressing both the maternal and fetal implications.
Instructions
Write a structured essay addressing each section heading below. Do not write bullet points alone — each section requires coherent explanatory prose supplemented by key data points. Cite the specific protocol, guideline, drug regimen, or investigation name where applicable (e.g., DIPSI vs IADPSG, Pritchard vs Zuspan, FOGSI, WHO). Word count: 900–1200 words total.
Length: 900–1200 words total across all six sections
What to Submit
1. Initial Assessment and Prioritisation
Guidance: Briefly outline which of the three concurrent complications (gestational hypertension/possible pre-eclampsia, anaemia, GDM) is the most immediately urgent and why. Define pre-eclampsia vs gestational hypertension for this clinical picture. Identify whether severe features are present and what would trigger escalation to pre-eclampsia with severe features.
2. Hypertensive Disorder: Investigation and Management
Guidance: List the targeted investigations required (BP monitoring, 24-hour urine protein or protein:creatinine ratio, renal function, liver enzymes, LDH, FBC, coagulation). State the BP threshold at which antihypertensive therapy is initiated and name the first-line agent. State the threshold for initiating MgSO4 prophylaxis and name the regimen (Pritchard or Zuspan) you would use, with doses. Describe the monitoring parameters for MgSO4 and the antidote.
3. Gestational Diabetes: Confirmation, Management, and Fetal Monitoring
Guidance: Confirm that the DIPSI protocol was correctly applied (non-fasting, 75 g, 2-h ≥140 mg/dL). Outline the management steps: dietary modification first, then insulin if targets not met (fasting <95, 2-h post-prandial <120 mg/dL). State why oral hypoglycaemic agents other than metformin require caution in pregnancy. Describe the fetal monitoring required for GDM (growth scan frequency, biophysical profile, amniotic fluid volume assessment) and when delivery should be timed.
4. Anaemia: Investigation, Treatment, and Effect on Fetal Growth
Guidance: State the WHO diagnostic threshold for anaemia in pregnancy and classify the severity at Hb 8.4 g/dL. Describe the investigation to confirm IDA (serum ferritin, peripheral smear). Outline the management escalation (oral iron → IV iron → transfusion) with the specific threshold for each step. Link the anaemia to the suspected IUGR: explain how anaemia reduces oxygen delivery to the placenta and contributes to fetal growth restriction.
5. Fetal Well-being Monitoring for Suspected IUGR
Guidance: Explain the clinical significance of the fundal height being 4 cm less than expected for dates (lag ≥3 cm is significant). Describe the Doppler surveillance protocol: umbilical artery Doppler (normal → raised PI → absent end-diastolic flow → reversed end-diastolic flow — graded escalation). Define when delivery should be expedited based on Doppler findings. Mention the role of MCA Doppler and biophysical profile in the surveillance protocol.
6. Integrated Delivery Planning and Counselling
Guidance: Summarise the optimal gestational age for delivery considering all three complications (target ≥37 weeks if stable; earlier if severe features develop). Outline counselling points for the patient on each condition. Identify the single most important preventive intervention that, if started earlier in the pregnancy (before 16 weeks), could have reduced the risk of both pre-eclampsia and IUGR — and name the drug and dose.
Grading Rubric — Medical Disorders in Pregnancy — Written Assignment Rubric
| Criterion | Points | Full-marks descriptor |
|---|---|---|
| Hypertensive disorder management: accurate classification (pre-eclampsia criteria), correct antihypertensive thresholds and agents, accurate MgSO4 regimen (Pritchard/Zuspan with doses), correct monitoring parameters and antidote | 25 pts | All four elements (classification, antihypertensives, MgSO4 regimen with named doses, calcium gluconate antidote) are accurate and protocol-consistent; severe-feature threshold correctly stated |
| GDM management: correct DIPSI protocol description, dietary-first then insulin approach, correct glycaemic targets, appropriate fetal monitoring frequency and delivery timing | 20 pts | DIPSI protocol correctly described (non-fasting, 2-h ≥140 mg/dL); glycaemic targets accurate; fetal surveillance schedule stated; delivery timing at ≥38 weeks (or earlier for macrosomia/polyhydramnios) |
| Anaemia diagnosis and tiered management: WHO threshold stated, IDA classification at Hb 8.4, investigation approach, correct escalation oral→IV→transfusion with thresholds | 20 pts | WHO threshold (Hb <11 g/dL) stated; Hb 8.4 classified as moderate; ferritin + smear as confirmatory investigations; oral iron first-line; IV iron for failure/intolerance; transfusion threshold (<7 g/dL or near term) correctly applied; link to IUGR via impaired oxygen delivery made explicit |
| IUGR surveillance: clinical significance of fundal height lag, Doppler staging (normal → raised PI → absent EDF → reversed EDF), correct escalation for each stage, delivery decision rationale | 20 pts | Fundal height lag correctly interpreted (≥3 cm significant); umbilical artery Doppler stages named in sequence with management action for each; reversed EDF correctly identified as the trigger for urgent delivery; MCA Doppler and BPP role mentioned |
| Integrated counselling and preventive strategy: coherent delivery plan across all complications, low-dose aspirin named as the preventive intervention with correct dose and timing | 15 pts | Delivery plan is coherent and accounts for all three complications; low-dose aspirin (75–150 mg/day before 16 weeks) explicitly named as the missed primary prevention opportunity; patient counselling for each condition outlined |
PEER REVIEW
Read your peer's assignment and score each of the five rubric criteria independently. For each criterion, identify: (1) one strength — a specific correct statement or clinical reasoning point; (2) one area for improvement — a factual gap, protocol omission, or reasoning error. Be specific: cite the section heading and the exact claim you are commenting on. Avoid generic feedback. Submit your peer review comments alongside the numerical score for each criterion.
