PERINEAL CARE

Classification of perineal tears
Perineal tears are common following vaginal delivery. There are classified as follows:

  • 1st degree – tear involving vaginal mucosa or perineal skin only
  • 2nd degree – involves perineal muscles
  • 3rd degree – involves external anal sphincter (EAS). This is further divided into 3A (less than 50% of EAS), 3B (more than 50% EAS) and 3C (full thickness anal sphincter tear)
  • 4th degree – includes rectal mucosa

Obstetric risk factors for anal sphincter injury

Maternal factors

  • Primiparity
  • Instrumental delivery – higher with forceps than vacuum extraction
  • Prolonged second stage of labour
  • Epidural analgesia
  • Midline episiotomy
  • Previous anal sphincter injury

Fetal factors

  • Birth weight greater than 4kg
  • Shoulder dystocia
  • Persistent occipito-posterior position during labour

3rd and 4th degree tears are repaired in theatre under regional anaesthesia.

A course of antibiotic and laxatives is usually prescribed in these circumstances. Give NSAIDS for analgesia if not contraindicated.

Postnatal physiotherapy for 6 – 12 weeks is offered to help prevent incontinence

Complications of perineal tears

Early

  • Haemorrhage
  • Pain - may interfere with maternal-neonate bonding
  • Wound infection / breakdown

Late

  • Faecal incontinence
  • Urinary incontinence
  • Persistent perineal pain / dyspareunia
  • Fistula formation
  • Psychological sequelae

Care of the perineum

  • Pelvic floor exercises and analgesia are important
  • Use warm clean water to clean perineum. No difference in healing when alternative remedies such as adding salt and antiseptics to water are used.
  • Wash perineum after every visit to the toilet
  • Do not use hair dryer over perineum. Use of toilet paper to pad dry the stitches is adequate
  • To help keep area dry, the use of breathable materials e.g. cotton briefs is better than synthetic materials
  • If using sanitary pads, change them frequently to help prevent infection
  • If there is swelling, can use cold ice packs to help reduce swelling and discomfort
  • Local anaesthetic creams are available at chemists but are expensive
