Post partum complication

Types of post partum complications:

1- post partum hemorrhage

2- puerperal sepsis

post partum hemorrhage

Postpartum hemorrhage is a significant cause of maternal morbidity and mortality.

Postpartum hemorrhage, the loss of more than 500 mL of blood after delivery, occurs in up to 18 percent of births and is the most common maternal morbidity in developed countries. Although risk factors and preventive strategies are clearly documented, not all cases are expected or avoidable.

 

 

 

 

 

Risk Factors for Postpartum Hemorrhage Prolonged third stage of labor Preeclampsia Mediolateral episiotomy Previous postpartum hemorrhage Twin pregnancy Arrest of descent Soft-tissue lacerations Asian ethnicity Augmented labor Forceps or vacuum delivery Midline episiotomy Nulliparity& high parity Systemic diseases

Type of post partum hemorrhage:

1-Primary post partum hemorrhage: occur during the first 24 hrs after delivery

2-Secondary post partum hemorrhage: occurring more than 24 hrs after delivery. It can occur along 6 weeks after delivery

1-Primary post partum hemorrhage

Major cause:A tonic uterus:

It is the most common cause of post partum hemorrhage with separation of the placenta ,the uterine sinuses cannot compressed effectively.

2-Trumatic:

Hemorrhage occurs due to trauma of the uterus, cervix, vagina following vaginal or operative delivery

Delay during episiotomy

3-Mixed

4-Blood coagulating disorder:

A acquired or congenital blood coagulation disorder.

Factors affecting efficient uterine contraction &retraction

Placental :1. Incomplete separation of placenta2. Retained cotyledon &membrane3. Placenta previa Prolonged labor Multiple pregnancy General anesthesia Full bladder Manipulation of the uterus during third stage

Clinical manifestation of PPH

If blood loss more than 750-1,250BP normal or decreasePulse normal or elevatedMild vasoconstrictionNormal urinary out putAware , alert, oriented

Atonic uterus (1,250-1,750)

Systolic BP<90 to 100mm/hgModerate tachycardia 100-120b/mModerate vasoconstriction, skin

pallor ,cold, moistDecrease urinary out putIncrease restlessness

Atonic uterus (1.800-2.500)Systolic BP <60mm/Hg Sever bradycardia >120 b/mPronounced vasoconstriction ( extreme

pallor, cold ,clammy cyanotic lips and finger)

Urinary output ceases (anurea)Mental stupor , lethargy, semi-comatose

*Uterus is flabby and become hard on massaging in a tonic PPH

*Uterus is well contracted in traumatic PPH

How is postpartum hemorrhage diagnosed? In addition to a complete medical history and

physical examination, diagnosis is usually based on symptoms, with laboratory tests often helping with the diagnosis. Tests used to diagnose postpartum hemorrhage may include:

estimation of blood loss (this may be done by counting the number of saturated pads, or by weighing of packs and sponges used to absorb blood; 1 milliliter of blood weighs approximately one gram)

pulse rate and blood pressure measurement hematocrit (red blood cell count) clotting factors in the blood

 

 

 

 

 

 

 

 

 

 

Prevention of PPH

Ante partum

Complete history-----to identify high risk pt who are likely to develop PPH

Improve health status especially to rise hg Hospital delivery of high risk pt who develop

polyhydramnios, multiple pregnancy, sever anemia

Routine blood grouping

Intrapartum PPH

Careful administration of sedativesAvoid hasty delivery of the infantProphylactic administration of oxytocin Avoid massaging the uterus before

separation of placentaExamine the utero –vaginal canal for trauma Effective management of the fourth stage of

labor

Management of Postpartum Hemorrhage

The aim of treatment of postpartum hemorrhage is to find and stop the cause of the bleeding as quickly as possible. Treatment for postpartum hemorrhage may include:

medication (to stimulate uterine contractions) manual massage of the uterus (to stimulate contractions) removal of placental pieces that remain in the uterus examination of the uterus and other pelvic tissues packing the uterus with sponges and sterile materials (to

compress the bleeding area in the uterus) tying-off of bleeding blood vessels laparotomy - surgery to open the abdomen to find the

cause of the bleeding. hysterectomy - surgical removal of the uterus; in most

cases, this is a last re

Observation of the mother

Record pulse, BP, every 15 min Palpate uterus every 15 min ----contraction Check temp /4 hrs Examine lochia for amount & consistency Examine IV infusion Hourly urine output Intake &output chart Relive anxiety Administer prophylactic antibiotic

Uterotonic Agents. Uterotonic agents include oxytocin, ergot

alkaloids (Methergine ), and prostaglandins.

Oxytocin stimulates the upper segment of the myometrium to contract rhythmically, which constricts spiral arteries and decreases blood flow through the uterus.30 Oxytocin is an effective first-line treatment for post

Technique of bimanual massage for uterine atony

Bimanual uterine compression massage is performed by placing one hand in the vagina and pushing against the body of the uterus while the other hand compresses the fundus from above through the abdominal wall. The posterior aspect of the uterus is massaged with the abdominal hand and the anterior aspect with the vaginal hand.
