Q

Discuss perineal breakdown / dehiscence
-Causes (3)
-Management (4)
-Complications (1)

A
  1. Causes
    -Infection
    -Haematoma
    -Poor surgical technique
  2. Management
    Assess for infection, necrotic tissue, suture fragments
    Limited evidence to guide management early vs delayed repair
    -Early re-suturing associated with less pain, less dyspareunia, earlier return to SI
    Treat any infection with antibiotics and gentle debridement.
    Consider re-suturing once clear and granulation tissue evident
  3. Complications

Q

Discuss prevention strategies for CS wound infection (8)

A
  1. Avoid unnecessary CS
  2. Optimise modifiable RF (smoking, glycemic control)
  3. Antibiotics prior to skin incision - reduces infection by 60-70%

  4. Hair removal at surgical site
  5. Vaginal preparation RR 0.43 esp in setting of SROM
  6. Skin prep chlorhex likely better than iodine but limited evidence
  7. Surgical technique
    -CCT to avoid endometritis
    -Good haemostasis
    -No evidence for irrigation
  8. Consider negative pressure dressing in high risk population but evidence sparse
