L10: Complications of 3rd Stage of Labor Flashcards
Retained Placenta
Def of Retained Placenta
Failure of delivery of placenta èin 30 minutes after delivery of fetus.
Incidence of Retained Placenta
1%
Types of Retained Placenta
- Retained separated placenta
- Retained non separated placenta
Etiology of Retained Separated Placenta
1) Uterine atony.
2) Constriction ring.
3) Rupture uterus.
Etiology of Retained non-separated Placenta
1) Uterine atony.
2) Abnormally adherent placenta
3) Abnormal shape of placenta: Placenta membranacea & succenturiate placent
Pathogenesis of Abnormally adherent placenta
Layer of fibrinoid tissue () trophoblasts & decidua basalis (Nitabuch layer) is absent or ↓ → chorionic villi penetrate deeply.
Etiuology & RF for Abnormally adherent placenta
Types of Abnormally adherent placenta
Complications of Retained Placenta
Dx & Managment of Causes of Retained Placenta
- Uterine atony
- Constriction ring
- Rupture uterus
- adherent placenta
Dx of Uterine atony
Severe bleeding + lax uterus
TTT of Uterine atony
Give ergometrine & do gentile uterine massage (to stimulate uterine contraction) then try to deliver placenta by 1 of the following:
a. Brandt-Andrew’s maneuver
b. Crede’s method:
c. Manual removal
TTT of Uterine atony
- Crede’s Method (Technique)
TTT of Uterine atony
- Crede’s Method (Complications)
TTT of Uterine atony
- Manual removal of placenta (Technique)
TTT of Uterine atony
- Manual removal of placenta (Complications)
- Perforation of uterus.
- Retained parts of placenta or membranes.
- Infection.
Dx of Constriction ring
TTT of Constriction ring
- Deep general anesthesia & amyl nitrite.
- Manual removal or placenta.
Dx of Rupture uterus
TTT of Rupture uterus
- laparotomy to deliver placenta.
- repair uterus or do hysterectomy.
Dx of adherent placenta
TTT of Adherent placenta
TTT of Adherent placenta
- Ordinary (simple) adherence & partial placenta accreta
- Remove as much as possible from placenta & insert uterine pack
- if bleeding continues → bilateral uterine artery ligation, bilateral internal iliac artery ligation or hysterectomy.
TTT of Adherent placenta
- Complete placenta accreta, placenta increta or placenta percreta
Puerperal Inversion of Uterus
Def of Puerperal Inversion of Uterus
Body of uterus is partially or totally turned inside out (it may occur during 3rd stage of labor è placenta is still attached or after 3rd stage is over).
Incidence of Puerperal Inversion of Uterus
Very rare (1/20000 of deliveries).
Types of Puerperal Inversion of Uterus
Etiology of Puerperal Inversion of Uterus
- Spontaneous inversion
- Induced (iatrogenic) inversion
