The field of obstetrics is one of the most dynamic branches of medicine, requiring clarity, precision, and rapid interpretation of clinical parameters. To support healthcare professionals in making time-sensitive decisions, concise and reliable clinical tools are essential. With great excitement, we introduce the 3rd Edition of 100 Thumb Rules Obstetrics & Fetal Nomograms Made Easy by Dr. Prashant Acharya, published by Elsevier in 2026. This updated edition has been meticulously crafted to assist practitioners, postgraduate students, and fetal medicine specialists in understanding obstetric metrics quickly and accurately.
Over the years, this book has earned a reputation for simplifying complex medical insights into practical “thumb rules” that clinicians can recall instantly, even during emergencies. In obstetrics, where calculations such as fetal growth ratio, gestational calculations, Doppler interpretations, and labor progression need fast interpretation, the ability to consolidate knowledge into easy-to-understand rules can significantly improve the quality of patient care. This latest edition advances that goal with updated charts, new guidelines, and enhanced visuals that reflect the latest developments in maternal-fetal medicine.
Whether you are a medical student beginning your journey in obstetrics or a seasoned practitioner looking for a quick clinical reference, 100 Thumb Rules Obstetrics & Fetal Nomograms Made Easy (3rd Edition) is a resource designed to improve your clinical accuracy and confidence.
What This Edition Offers
The 3rd Edition brings together 100 essential obstetric thumb rules that simplify fetal assessments and maternal evaluations in routine and high-risk pregnancies. These thumb rules condense key concepts into short, memorable statements that make clinical decision-making substantially easier.
The book also includes fetal nomograms, which are vital graphs and charts used to evaluate fetal parameters such as head circumference, femur length, abdominal circumference, Doppler indices, and growth curves. Accurate interpretation of these parameters is essential in identifying potential complications early, such as growth restriction, macrosomia, oligohydramnios, or abnormal Doppler flow patterns. This edition updates these nomograms with modern standards, making it clinically relevant for contemporary practice.

Why This Book Matters for Obstetrics Practice
Healthcare professionals in obstetrics face multiple time-sensitive decisions each day. This is one specialty where delays or errors can significantly affect both maternal and fetal outcomes. In such scenarios, having a reliable, quick-reference guide becomes essential.
Here’s why this book is indispensable:
Quick Decision-Making
Thumb rules eliminate the need for lengthy calculations. Clinicians can rapidly evaluate fetal parameters and maternal indicators, making timely decisions that improve patient outcomes.
Increased Clinical Accuracy
Accurate fetal assessment requires precise interpretation of biometric parameters. Updated nomograms improve diagnostic precision, reducing the risk of misinterpretation.
Bridges Theory and Practice
Many medical books explain concepts but do not simplify their practical application. This book does both—ensuring readers understand concepts and can apply them instantly.
Helps Standardize Assessments
Clinical assessments become more uniform when practitioners rely on established thumb rules and standardized nomograms.
Enhances Training for Students and Residents
Students often struggle with remembering obstetric formulas and ranges. Thumb rules simplify these concepts, improving academic performance and clinical readiness.
Detailed Breakdown of What Readers Can Expect
1. Maternal Assessment Thumb Rules
Readers will find rules for evaluating maternal blood pressure, gestational diabetes indicators, anemia cut-off values, weight gain guidelines, and more. These rules help practitioners quickly categorize maternal health risks.
2. Labor and Delivery Thumb Rules
This segment covers cervical dilation progress, expected labor duration, partogram interpretation, and fetal station calculations. Such insights are invaluable for managing labor efficiently and safely.
3. Fetal Growth Parameters
The book includes rules for interpreting bi-parietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL), and estimated fetal weight (EFW). These rules help identify growth restriction or accelerated growth.
4. Doppler Studies
Doppler evaluations require precise interpretation. This edition explains rules for interpreting the umbilical artery, MCA, and ductus venosus Doppler indices.
5. Trimesters & Screening Evaluations
The book helps readers interpret first-trimester screening markers, second-trimester anomaly scan thresholds, and third-trimester risk assessments.
6. Clinical Case Scenarios
Some sections provide real-world clinical examples that help readers apply thumb rules to common obstetric problems.
