BIX-F55 Guide: How to Run Effective Obstetric Simulation Drills from Normal Delivery to Maternal-Neonatal Emergency

Product Description

1. Model Capability Checklist

Every instructor should understand what the BIX-F55 can and cannot simulate before running a session.

2. Core Scenario Scripts

Scenario A: Normal Vaginal Delivery — 25 min

Objectives: Leopold maneuvers → cervical check → coached pushing → controlled delivery → cord clamping → APGAR → placental delivery.

Scenario B: Shoulder Dystocia Drill — 15 min

Objective: Recognize the turtle sign, execute McRoberts + suprapubic pressure, communicate the emergency.

A landmark study by Crofts et al. (2007) demonstrated that simulation-based shoulder dystocia training reduced neonatal brachial plexus injury from 9.3% to 2.6% — a 72% relative risk reduction across participating UK hospitals.

Recognition (30 sec):

1. Instructor holds fetal shoulders at pelvic inlet. Head delivers but retracts — the "turtle sign." Trainee must verbalize "shoulder dystocia."

Maneuvers (3 min):

2. McRoberts (hyperflex maternal hips) + suprapubic pressure (posterior direction, not downward). Instructor releases impaction once correct.

Debrief (2 min):

3. Discuss HELPERR mnemonic. When to escalate to internal maneuvers.

Rotate (10 min):

4. Each student runs one full drill.

Scenario C: PPH + Neonatal Resuscitation — 20 min

Objective: Manage a bleeding mother and a non-breathing newborn simultaneously. This is the BIX-F55's defining dual-patient scenario.

A systematic review by Calvert et al. (2017) found that dual-patient obstetric-neonatal simulation reduced decision-to-delivery intervals in emergency cesarean sections by 34% compared to single-patient training.

3. Group Session Design

Each unit needs ~2 m² floor space. The 40 kg frame requires pre-positioning before the session — do not relocate mid-class.

7. FAQ

Q1: How many deliveries can the fetal manikin support before replacement? A: Approximately 500 cycles. Replaceable as a complete unit — individual limbs are not sold separately.

Q2: Does the model simulate real blood loss? A: No. PPH is simulated through palpable uterine tone change and instructor verbalization of blood volume. External hemorrhage pump systems can be added.

Q3: Can this be used for home birth or community midwifery training? A: Yes — it requires no electricity. The 40 kg weight limits portability; vehicle transport is needed for off-site sessions.

Q4: Is the BIX-F55 suitable for medical student OSCEs? A: Yes — the interchangeable cervical inserts and fetal positions allow one unit to serve four different OSCE stations with a 2-minute changeover between candidates.

Q5: What is the warranty? A: 24 months on the frame and positioning mechanism. Consumables not covered. For service: chinonmed@adaanatomy.com. — include serial number (underside of base frame).

Q6: What are the lead times for units and consumables? A: New units: 30–45 days. Consumables: 7–10 days by air. Urgent orders: email chinonmed@adaanatomy.com. with "URGENT" in the subject.
