Obstetric shuck possible causes

List of all causes of shock pertaining  Obstetrics (both ANC period, Labour period & Postpartum) , admittedly a bit theoretical Causes of shock that we may face in ANC period as well-worth remembering

A)                    Haemorrhagic shock excessive blood loss may be due to:

1)                     Incomplete abortion::Causes of bleeding early in pregnancy  say Disturbed ectopic pregnancy.

.

  2; Causes of antepartum haemorrhage.

3Causes of postpartum haemorrhage.

B)                     Neurogenic shock painful conditions my be due to:

1   Disturbed ectopic pregnancy.

   2.Concealed accidental haemorrhage.

 3. Forceps or breech extraction before full cervical dilatation.

 4. Cumbersome / Rough internal version.

 5, Pushing the uterus son after birth of a baby à Crédé’s method.

 6. Rupture uterus.   7          

 7. Acute inversion of the uterus.

Rapid evacuation of the uterine contents as in precipitate labour and rupture of membranes in polyhydramnios. This is accompanied by rapid accumulation of blood in the splanchnic area due to sudden relief of pressure (splanchnic shock).

C)                     Cardiogenic shock: ineffective contraction of the cardiac muscle due to

Myocardial infarction.         

Heart failure.

D)                   Endotoxic shock: generalised vascular disturbance due to release of toxins.

Anaphylactic shock: caused by sensitivity to drugs.

E)                      Misc causeds:-Other causes:

Embolism: amniotic fluid, air or thrombus.

F)                      Anaesthetic complications:  Drug allergy/ as Mendelson's syndrome.

The shock may be caused by more than one factor as:

Incomplete abortion: leads to haemorrhagic and endotoxic shock.

Disturbed ectopic and rupture uterus: lead to haemorrhagic and neurogenic shock.
