  • Increasedd BMI
  • Para 4 or more
  • Antepartum haemorrhage
  • Overdistention of uterus
  • Uterine abnormalities
  • Maternal age >35 yrs
23
Q

24
Q

How would you manage someone with uterine atony?

Study These Flashcards
A
  1. Phyical methods to contract - bimanual compression, massage
  2. Medical management
    • 500 mg ergometrine IV
    • 40U oxytocin infusion
    • Consider 800 mg misoprostol PR - if bleeding continues
    • Consider 250 mg Carboprost
  3. Surgical management
25
What is the general principles to PPH management?
* **Empty uterus** - deliver foetus, remove placenta * **Treat atony** - Massage, bimanual compression, medications * **Repair genital tract damage**
26
What are causes of secondary PPH?
* **Retained products** * **Endometritis** * **Tear/trauma**
27
What are the main problems that can arise in the post-partum period?
* **PPH** * **VTE** * **Sepsis and puerpural pyrexia** * **Post-partum depression/psychosis**
28
What are causes of endometritis?
* **C-section** * **Prelabour rupture of membranes** * **Intrapartum chorioamnionitis** * **Prolonged labour** * **Multiple pelvic examinations** * **Intenral foetal monitoring**
29
What are symptoms of endometritis?
* **Fever** * **Foul smelling, profuse, bloody discharge** * **Features of sepsis**
30
What are causes of puerperal pyrexia/sepsis?
* **Endometritis** * **Perineal wound infection** * **Mastitis/Breast abscess** * **UTI** * **Thrombophlebitis** * **Abdominal wound infection**
31
What investigations would you do if you suspected puerperal infection/pyrexia/sepsis?
* **Bedside** - Urine dipstick, cervical/lochia swab, wound swabs, throat swabs, sputum culture * **Bloods** - FBC, U+E's, blood cultures consider ABG for lactate * **Imaging** - CXR
32
How would you generally manage someone with puerperal sepsis?
* **Supportive** - antipyretics, fluids * **Antibiotics** - broad spectrum if no obvious cause
33
How long after delivery is contraception needed?
\>3 weeks - breast feeding can be used as contraception (lactational amenorrhoea)
34
What is the pharmacological options in the management of PPH?
* **Oxytocin** - slow injection or IV infusion (30 IU in 500ml saline at 125ml/hr) * **Synometrine/ergometrine IM** * **Carboprost IM 250mcg every 15 minutes - max 2 mg** * **Misoprostol** * **Tranexamic acid**
35
How would you manage endometritis?
* **Urgent IV Abx** * **Uterine curettage**
36
How does breastfeeding cause amenorrhoea?
Suckling disrupts frequency and amplitude of gonadotrophin surges so that although there is gonadotrophin rise in response to falling placental sex steroids after delivery, ovulation does not occur
37
When is the average 1st menstruation in a fully breastfeeding mother post-partum?
28 weeks - this method of contraception is 98% effective
38
How would you manage the risk of VTE after vaginal delivery?

47
Risk factors for perineal trauma
* Primigravida * Large babies * Precipitant labour * Shoulder dystocia * Forceps
48
Describe the grades of perineal trauma
* 1st degree = tear within vaginal mucosa only (superfical, no muscle involvement) * 2nd degree = tear into subcur tissue (injury to muscle not sphincter) * 3rd degree = laceration extends into external anal sphincter * 4th degree = lacteration extends through external anal sphincter into rectal mucosa
