Fetal distress

Fetal distress
Presentation by:LIN QI DE

Fetal distress is defined as depletion of oxygen and accumulation of carbon dioxide,leading to a state of “hypoxia and acidosis ” during intra-uterine life.

Definition
Maternal factors

* Microvascular ischaemia(PIH)
* Low oxygen carried by RBC(severe anemia)
* Acute bleeding(placenta previa, placental abruption)
* Shock and acute infection
* obstructed of Utero-placental blood flow

Etiology
Placenta umbilical factors
* Obstructed of umbilical blood flow
* Dysfunction of placenta
* Fetal factors
* Malformations of cardiovascular system
* Intrauterine infection

Hypoxiaaccumulation of carbon dioxide
Respiratory Acidosis
Intestinal peristalsis
Relaxation of the anal sphincter
Meconium aspiration
Fetal or neonatal pneumonia
