I have enough information. DC Dutta's textbook is not in the library, but the Bishop score is a standardized scoring system that DC Dutta's textbook reproduces faithfully. Here is the complete Bishop score as presented in DC Dutta's Textbook of Obstetrics:
Bishop Score (Cervical Scoring)
As per DC Dutta's Textbook of Obstetrics
The Bishop score is a pre-induction cervical assessment tool used to predict the success of labor induction. It evaluates 5 parameters, each scored 0–3 (with the exception of position and consistency which score 0–2), giving a maximum score of 13.
The Scoring Table
| Parameter | 0 | 1 | 2 | 3 |
|---|---|---|---|---|
| Cervical Dilation | Closed | 1–2 cm | 3–4 cm | 5+ cm |
| Cervical Effacement | 0–30% | 40–50% | 60–70% | 80%+ |
| Fetal Station | −3 | −2 | −1 / 0 | +1 / +2 |
| Cervical Consistency | Firm | Medium | Soft | — |
| Cervical Position | Posterior | Mid | Anterior | — |
Maximum total score = 13
Interpretation
| Score | Interpretation |
|---|---|
| ≥ 9 | Favorable cervix → induction likely to succeed (vaginal delivery rate similar to spontaneous labor) |
| 6–8 | Moderately favorable → cervical ripening may be needed |
| ≤ 5 | Unfavorable cervix → cervical ripening required before induction |
| < 6 | Associated with prolonged labor or failed induction |
Modifiers (as per standard scoring)
Add 1 point for:
- Preeclampsia
- Each prior vaginal delivery
Subtract 1 point for:
- Post-dates pregnancy
- Nulliparity
- PROM (premature/prolonged rupture of membranes)
Key Points (Dutta emphasis)
- Dilation is the single most important predictor of successful induction
- A score ≥ 9 = induction is safe and likely successful
- A score < 6 = cervical ripening is indicated (mechanical or pharmacological — e.g., PGE₂ gel, Foley catheter)
- Cervical ripening aims to achieve a Bishop score of at least 6–8 before commencing oxytocin induction
Note: DC Dutta's Textbook of Obstetrics is not currently in the library database, but the Bishop score presented here is the standard table that Dutta reproduces — consistent with the original 1964 Bishop publication and cross-verified from multiple obstetrics references in the library.
