Complications of labour and peuperium Flashcards
Preterm labour and birth
labour 20-37/40
Preterm labour and birth risk factors
- Demographic/psychological factors
- PET
- PROM
- Uterine abnormalities
- Nutritional factors
- exposure to toxins (smoking)
Abnormal uterine contractions
contractions lack fundal dominance and increased uterine resting tone
Hypotonic uterus
short and weak contractions
Hypertonic uterus
stong and long contractions, short intervals
abnormal uterine contractions implications
- Slow/no Cx dilation
- uterine damage
- long labour
Malposition OP manifestations
Depression inferior to umbilicus
High deflexed head
spine felt on mothers flank
Possible outcome of OP labour
Long rotation to OA
DTA of head
Short rotation to persistant OA
Malpresentation definition
Any presentation other than vertex
Obstructed labour definition
Failure of descent/advancement of presenting part
Potential causes of obstructed labour (4)
- Cephalopelvic distroportion
- Malpresentation
- Foetal abnormalilties
- Abnormalities of reproductive tract
Amniotic Fluid Embolism process
Amniotic fluid forced in to maternal venous circulation > circulates in maternal venous system > lodged in pulmonalry circulation reduces blood flow beyond that point > congestion and pulmonary hypertension > inc right ventricle pressure > hypoxia due to reduced O2 blood returning to heart > Pulmonalry spasn > widespread vasoconstriction > coagulation > dec BP and CO > cardiorespiratory collapse/shock
Amniotic fluid embolism manifestations (5)
- Chest pain/dyspnoea
- Hypotension
- Tachycardia
- Cyanosis
- Collapse
PPH pathophysiology
- Depends on cause
- reduced ability of uterus to contract
- decreased ability for coagulation
- trauma/operative delivery
Postpartum infections
Infections of reproductive and urinary tract and perineal/CS wounds.
