# Managing Labor and Delivery

Structures labor documentation with cervical change tracking, partogram management, Bishop scoring, and delivery summary per ACOG and WHO guidelines.

## Why This Skill Exists

Labor and delivery documentation is among the most legally scrutinized areas in all of medicine. Obstetric malpractice claims frequently center on whether labor progress was appropriately monitored, whether arrest disorders were timely recognized, and whether the decision-to-incision interval for emergency cesarean delivery was documented. ACOG/SMFM redefined labor arrest criteria in the Safe Prevention of the Primary Cesarean Delivery consensus (Obstetric Care Consensus No. 1), establishing new thresholds that must be applied before diagnosing failed induction or labor arrest.

Accurate documentation of cervical change, contraction patterns, fetal station, and maternal/fetal status at every exam protects patients and providers. This skill enforces the contemporary evidence-based labor management framework.

## Checkpoint A: Pre-Draft Intake (Mandatory)

1. **Gestational age and EDD** — confirmed dating method? (Default: pull from prenatal record)
2. **Parity** — nulliparous vs. multiparous? Prior vaginal delivery vs. prior cesarean? (Default: from OB history)
3. **Membrane status** — intact, spontaneous rupture (SROM), artificial rupture (AROM)? Time of rupture? (Default: confirm from admission note)
4. **GBS status** — positive, negative, unknown? Antibiotic prophylaxis initiated? (Default: from prenatal labs)
5. **Induction vs. spontaneous labor** — if induction, what is the indication and Bishop score at start? (Default: document from admission)
6. **Anesthesia status** — epidural in place, IV analgesia, or unmedicated? (Default: note current pain management)
7. **Fetal presentation** — cephalic, breech, transverse? Confirmed by ultrasound? (Default: from admission exam)
8. **High-risk flags** — preeclampsia, VBAC candidate, multiple gestation, prior shoulder dystocia? (Default: review risk list)

### Documents to Request

- Admission history and physical
- Prenatal record summary (OB flow sheet)
- Prior operative reports (if VBAC candidate)
- EFM tracing records
- Nursing labor flowsheet
- Anesthesia records
- Medication administration record (oxytocin log)

## Step 1: Assess Cervical Status Using the Bishop Score

The Bishop score determines cervical favorability for induction:

| Factor | 0 | 1 | 2 | 3 |
|---|---|---|---|---|
| Dilation (cm) | Closed | 1–2 | 3–4 | ≥ 5 |
| Effacement (%) | 0–30 | 40–50 | 60–70 | ≥ 80 |
| Station | −3 | −2 | −1 or 0 | +1 or +2 |
| Consistency | Firm | Medium | Soft | — |
| Position | Posterior | Mid | Anterior | — |

- **Bishop score ≥ 8:** Favorable cervix — high likelihood of successful induction
- **Bishop score < 6:** Unfavorable cervix — consider cervical ripening (misoprostol, dinoprostone, mechanical balloon)

Document the Bishop score at admission and before any induction agent is administered.

## Step 2: Monitor Labor Progress per ACOG/SMFM Criteria

### First Stage — Latent Phase
- Cervix 0–6 cm
- **No strict time limit** per ACOG Safe Prevention consensus
- Prolonged latent phase: > 20 hours (nulliparas), > 14 hours (multiparas) — this alone is NOT an indication for cesarean
- Interventions: ambulation, hydration, rest, consider amniotomy if membranes intact

### First Stage — Active Phase
- Begins at 6 cm (redefined from older 4 cm threshold)
- Expected dilation rate: ≥ 1 cm/hour is NOT required
- **Arrest of active phase** = ≥ 6 cm dilation with ruptured membranes AND no cervical change for:
  - ≥ 4 hours with adequate contractions (≥ 200 Montevideo units)
  - ≥ 6 hours with inadequate contractions despite oxytocin augmentation

### Second Stage
- From complete dilation to delivery of the infant
- Allow at least:
  - **3 hours** for nulliparas (4 hours with epidural)
  - **2 hours** for multiparas (3 hours with epidural)
- Arrest of second stage requires these minimums to be met before diagnosing arrest
- Active pushing should be documented with maternal effort assessment

Document every cervical exam with: time, dilation, effacement, station, position, and contraction adequacy.

## Step 3: Manage Oxytocin Augmentation

When augmentation is indicated, document using a standardized protocol:

| Parameter | Low-Dose Protocol | High-Dose Protocol |
|---|---|---|
| Starting dose | 0.5–2 mU/min | 6 mU/min |
| Increment | 1–2 mU/min | 3–6 mU/min |
| Interval | Every 30–40 min | Every 15–40 min |
| Maximum dose | 20–40 mU/min | 40–42 mU/min |

**Tachysystole management** (> 5 contractions in 10 minutes averaged over 30 minutes):
1. Decrease or discontinue oxytocin
2. Maternal repositioning (lateral decubitus)
3. IV fluid bolus
4. Consider terbutaline 0.25 mg SQ if persistent
5. Assess FHR tracing for associated decelerations

Document: oxytocin start time, each dose change with time, contraction frequency/strength, and any tachysystole episodes with management.

## Step 4: Document the Delivery

### Vaginal Delivery Summary
- Time of delivery
- Presentation and position at delivery (e.g., OA, OP, OT)
- Delivery mechanism (spontaneous, vacuum-assisted, forceps-assisted)
- Episiotomy (type) or laceration (degree: 1st through 4th)
- Cord management (delayed cord clamping duration, nuchal cord, cord gases sent)
- Placenta delivery (spontaneous vs. manual, time, completeness)
- Estimated blood loss (EBL)
- Infant status: sex, weight, Apgar scores (1 min, 5 min, 10 min if needed)
- Skin-to-skin initiation

### Shoulder Dystocia Documentation (if applicable)
Document using the HELPERR mnemonic: time of head delivery, time of body delivery, maneuvers used (McRoberts, suprapubic pressure, Rubin, Wood screw, delivery of posterior arm, Gaskin), and total head-to-body delivery interval.

## Step 5: Immediate Postpartum Assessment

- Uterine tone (firm vs. boggy)
- Fundal massage performed
- Active management of third stage (oxytocin 10–40 units in 1 L, or IM 10 units)
- Laceration repair details (suture type, technique)
- Hemodynamic stability (vital signs q15 min × 1 hour, then q30 min × 1 hour)
- Quantitative blood loss (QBL) measurement
- Hemorrhage risk assessment per CMQCC bundle

---

## Checkpoint B: Post-Draft Alignment (Mandatory)

1. **Are all cervical exams documented** with time, dilation, effacement, station, and contraction adequacy?
2. **Does the arrest diagnosis meet ACOG/SMFM criteria** — 4 hours adequate or 6 hours inadequate contractions at ≥ 6 cm with ruptured membranes?
3. **Is oxytocin management fully logged** — start time, dose changes, tachysystole events?
4. **Is the delivery summary complete** — including Apgars, EBL, laceration degree, and cord management?
5. **Is the timeline internally consistent** — admission → active labor → complete → delivery → placenta → postpartum, with no unexplained gaps?

## Guidelines

1. **Never diagnose labor arrest before 6 cm** — per ACOG, the latent phase should be given adequate time and is not an indication for cesarean.
2. **Document contraction adequacy** — use Montevideo units when IUPC is in place; otherwise describe frequency and palpated strength.
3. **Time-stamp every event** — cervical exams, membrane rupture, medication changes, delivery, and placenta delivery all require exact times.
4. **Use standardized laceration grading** — 1st degree (mucosa/skin only), 2nd degree (into perineal muscles), 3rd degree (into anal sphincter), 4th degree (through rectal mucosa).
5. **Document VBAC counseling** — if applicable, record the discussion of risks (0.5–0.9% uterine rupture rate for one prior low-transverse cesarean), benefits, and patient decision.
6. **Report quantitative blood loss** — replace "EBL" with measured QBL where institutional protocol supports it.
7. **Flag meconium** — document consistency (thin vs. thick) and whether neonatal team was present at delivery.
