Obstetric Theatre Nursing
On this page
Direct answer
Obstetric theatre nursing is emergency surgery conducted on two patients at once — an obstetric one whose physiology demands a 15-degree left lateral tilt to offload the inferior vena cava, and a foetal one whose condition sets the clock. The organising structure is the WHO Surgical Safety Checklist in three moments — sign in before induction, time out before incision, sign out before the patient leaves — covering identity, consent, anaesthesia and equipment checks, antibiotic prophylaxis (commonly within about 60 minutes before skin incision), instrument and swab counts, and blood availability. Because caesarean sections are frequently category-1 emergencies, the discipline lies in having the routine so rehearsed that speed never buys an error: a discrepancy in the swab count before closure stops the operation, always.
What you must remember
- Checklist structure: sign in (identity, procedure, consent, site, anaesthesia check, pulse oximeter, allergies, blood availability), time out (team introduction, confirmation, antibiotic given, anticipated critical events), sign out (counts complete, specimen labelled, recovery plan).
- Aortocaval compression: from roughly 20 weeks, supine positioning compresses the inferior vena cava — a 15-degree left tilt or right hip wedge is used in every obstetric procedure until delivery.
- Antibiotic timing: prophylaxis commonly within about 60 minutes before incision, frequently already on induction for category-1 sections, per policy.
- Count discipline: instruments, swabs and sharps counted at the start, when a cavity closes, and at skin closure; a discrepancy means re-count, search, and intraoperative radiograph before the patient leaves theatre.
- Category-1 readiness: the decision-to-delivery target is commonly 30 minutes, so caesarean kits, neonatal resuscitation equipment and O-negative blood access are maintained ready at all times.
- Neonatal team: a separate person or team whose only patient is the newborn — warmer, suction, bag-mask checked before every case, not fetched after.
- Obstetric specifics: uterotonics prepared with anaesthetic timing, blood loss measured by swab weighing and graduated collection, thromboprophylaxis planned in recovery.
A category-1 section, from call to sign out
The call comes at 2 a.m.: bradycardia in labour, category-1 caesarean. What separates a calm theatre from a dangerous one is that nothing is being decided now that could have been decided earlier — the pre-packed obstetric trolley is standardised, the resuscitation cot is checked every shift, and the checklist runs compressed but complete. In theatre the scrub and circulating nurse count aloud before draping: instruments, swabs, needles, each number spoken and recorded — the safety net honoured at closure no matter how urgent the opening was. The patient goes on the table with a right hip wedge for 15-degree tilt, and during time out the anaesthetist, surgeon and nurse each state anticipated concerns — estimated blood loss, likelihood of hysterotomy extension, neonatal team standing by.
After delivery the work runs in parallel streams: the neonatal stream resuscitates at the warmer with skin-to-skin contact restored once the baby stabilises; the obstetric stream manages the third stage with oxytocin and hands over the weighed swabs for measured blood loss; the nursing stream shepherds the counts, and at sign out confirms the specimen labelled aloud with two identifiers, counts complete, and recovery instructions with thromboprophylaxis handed over in words. The documentation ends with times: call, arrival, decision, incision, delivery — the audit data that will judge the unit's response tomorrow, recorded by the people who kept the discipline tonight.
Where students slip
The examinable error is treating the checklist as paperwork — its power is spoken team confirmation, and "what happens during time out" expects the named elements including team member introduction, which students routinely omit. The second slip is the tilt: aortocaval compression persists until delivery, so positioning is a nursing responsibility visible in supine hypotension and foetal compromise. The count question has one right answer: a discrepancy before closure stops the procedure for re-count and search, with radiography if unresolved — "closing and observing" is the fail answer, because a retained swab is precisely the harm the ritual blocks. And antibiotic timing is checked against incision time, not induction time.
Frequently asked questions
What are the three stages of the WHO Surgical Safety Checklist?
Sign in before induction of anaesthesia, time out before skin incision, and sign out before the patient leaves the operating room.
Why is a 15-degree left tilt used in obstetric surgery?
To displace the gravid uterus off the inferior vena cava and aorta, preventing supine hypotension and placental underperfusion until the baby is delivered.
What must happen if the swab count is incorrect before closure?
Closure stops: re-count, systematic search of field, drapes and floor, and intraoperative imaging if unresolved — the patient does not leave with an unexplained count.
When should antibiotic prophylaxis be given for caesarean section?
Commonly within about 60 minutes before incision, frequently at induction, per unit policy and current guidance.
What is the decision-to-delivery target for a category-1 caesarean?
Commonly 30 minutes from decision to delivery — the reason obstetric theatres maintain ready kits, checked neonatal equipment and immediate blood access.
