SEMINAR ON POST PARTUM HAEMORRHAGE PRESENTED BY- Ms Priyashree Pal 4 th yr B.Sc Nursing
INTRODUCTION Third stage is the most crucial stage for the mother. Fatal complications may appear unexpectedly in an otherwise uneventful first / second stage.
Complications of third stage of labour:- POSTPARTUM HAEMORRHAGE RETENTION OF PLACENTA SHOCK-HAEMORRHAGIC OR NON-HAEMORRHAGIC PULMONARY EMBOLISM UTERINE INVERSION
DEFINITION QUANTITATIVE DEFINITION- It refers to the amount of blood loss in excess of 500ml following birth of the baby. CLINICAL DEFINITION- Any amount of bleeding from or into the genital tract following birth of the baby up to the end of the puerperium which adversely affects the general condition of the patient evidenced by rise in pulse rate and falling blood pressure
Depending upon the amount of blood loss, PPH can be:- MINOR (<1 L) SEVERE (>2L) MAJOR (>1L)
INCIDENCE The incidence widely varies mainly because of lack of uniformity in criteria used in definition and the extent of use of prophylactic ergometrine. 1-5% amongst hospital deliveries.
CLASSIFICATION
1. PRIMARY POST PARTUM HAEMORRHAGE It is the haemorrhage occurring during the third stage of labour and within 24 hrs of delivery. Third stage haemorrhage- bleeding occurs before expulsion of placenta. True PPH- bleeding occurs subsequent to expulsion of placenta
CAUSES
a. ATONIC UTERUS(80%) Refers to imperfect contraction and retraction of the uterus which cannot compress the torn sinuses after separation of placenta leading to bleeding@ 500-800ml/min.
ATONIC UTERUS
CAUSES OF UTERINE ATONICITY
1. Grand multipara 2. Over distension of the uterus
3.Incomplete separation of the placenta 4.Mismanaged third stage of labour
5.Malnutrition and anemia
6.Precipitated labour 7.Prolonged labour
8.Anesthesia
9.Malformation of the uterus
10.Uterine fibroid
11.Constriction ring
12.Placenta praevia
13.Placental abruption
14.A full bladder
b. TRAUMATIC HAEMORRHAGE(20%) Trauma involves usually the cervix, vagina, perineum (episiotomy wound and lacerations), para-urethral region and rarely uterine rupture. CAUSES Perineal, vaginal and cervical tears Lower segment tears Uterine rupture Vulval injuries
1.Perineal, vaginal and cervical tears 2.Vulval injuries
3.Cervical tear
4. Uterine rupture 5.Lower segment tears
c. BLOOD COAGULATION DISORDERS It may be due to diminished procoagulants or increased fibrinolytic activity. The firmly retracted uterus can usually prevent bleeding even if serious clotting disorders are present. CAUSES:-
Abruptio placentae
Jaundice in pregnancy
Thrombocytopenic purpura
Intra uterine death
HELLP Syndrome
Disseminated intravascular coagulation
Excessive fibrinolysis
Combination of Atonic and traumatic causes. d. Mixed
CLINICAL FEATURES Vaginal bleeding- slow or copious flow Pallor Rising pulse rate Falling blood pressure Altered level of consciousness-restless or drowsy Enlarged uterus- boggy on palpation Maternal collapse
Anxiety Complaint of thirst Sinking quickly into a condition of syncope with shallow respiration Death The effect of blood loss depends on:- Pre –delivery hemoglobin level Degree of pregnancy induced hypervolemia Speed of blood loss
DIAGNOSIS State of uterus as felt per abdomen Traumatic hemorrhage- uterus well contracted Atonic hemorrhage- uterus flabby , becomes hard on massaging
PREVENTION ANTENATAL Improvement of the health status Hemoglobin level>10 gm/dl Screening of high risk patients (twins, polyhydramnios, grand multipara, APH, severe anemia) Delivery of high risk patients in well equipped hospitals Blood grouping
2.INTRANATAL Slow delivery of baby- push rather than pull Expert obstetric anesthetist -local or epidural in case of forceps, ventouse or breech delivery Spontaneous separation and delivery of placenta even during caesarean section. Active management of third stage of labour. Avoid the temptation of fiddling/ kneading with the uterus or pulling the cord.
Examination of the placenta and membranes as routine. Oxytocin infusion should be continued at least 1 hr after delivery. Exploration of uterovaginal canal for evidence of trauma Observation of patient for about two hours after delivery Send patient to ward only when uterus becomes hard and contracted.
MANAGEMENT PRINCIPLES OF MANAGEMENT To empty the uterus of its contents and to make it contract. To replace the blood loss , on occasions patient may be in shock, in that case patient is managed for shock first. To ensure effective haemostasis in traumatic bleeding.
STEPS OF MANAGEMENT PLACENTAL SITE BLEEDING Palpate the fundus and massage the uterus to make it hard. Ergometrine 0.25mg or Methergin 0.2mg IV or Oxytocin 10 units IM. Start a normal saline/RL drip Arrange for blood transfusion if necessary
To catheterize the bladder if full. to give antibiotics (Ampicillin 2 gm and Metronidazole 500mg) Signs of placental separation Placenta not separated Shock Fundal pressure Cord traction Manual removal Resuscitation
2. TRAUMATIC BLEEDING Exploration of utero -vaginal canal under general anesthesia after the placenta is expelled and haemostatic sutures are applied on the offending sites.
STEPS OF MANUAL REMOVAL OF PLACENTA Step 1- General anesthesia or deep sedation with 10mg Diazepam IM. Lithotomy position Step 2- One hand is introduced into the uterus after smearing with antiseptic solution in cone shaped manner. Other hand making the cord taut. Fingers of uterine hand locate the margin of the placenta.
Step 3- Counter pressure on uterine fundus by the hand placed over the abdomen till complete separation of placenta. Step 4- When placenta margin is reached , fingers are insinuated between the placenta and the uterine wall with back of hand in contact with the uterine wall.
Step 5- Extraction of placenta by cord traction by other hand. Uterine hand still inside to explore cavity to find any residual bits or cotyledons of placenta. Step 6- IV Ergometrine 0.25 mg is given Uterine hand gradually removed Massage with external hand Inspection of cervico-vaginal canal Step 7- Inspection of placenta and membranes for completeness Make sure uterus is hard and contracted.
MANAGEMENT OF TRUE POST PARTUM HAEMORRHAGE PRINCIPLES:- simultaneous approach Communication Resuscitation Monitoring Arrest of bleeding
MANAGEMENT IMMEDIATE MEASURES Call for extra help Put in 2 large bore IV cannula Keep patient flat and warm. Send blood for group and cross-matching and ask for 2 units of blood. Infuse rapidly 2L of NS / hemaccel Give oxygen by mask 10-15 L/min.
Start 20 units of Oxytocin in 1L of NS IV @60 drops/min Monitor- Pulse Blood pressure Urine output Drugs- type, dose and time Type and amount of fluid patient has received Central venous pressure
ACTUAL MANAGEMENT A- ATONIC Step 1- Massage the uterus to make it hard and express the blood clot
Methergin 0.2mg is given IV Morphine 15mg may be given IM Inj. Oxytocin drip is started at the rate of 30-40 drops per min. Empty the bladder Examine expelled placenta and membranes.
Step 2-In refractory cases:- Inj. 15 methyl PGF2 α 250 μ g IM in the deltoid muscle every 1-2 hrs. Misoprostol 1000 μ g per rectum is effective
Step 3- Uterine massage and bimanual compression.
Step 4- Uterine tamponade Tight intrauterine packing Insertion of Sengstaken Blakemore tube into uterine cavity and inflating balloon with 200ml of NS
Tight intrauterine packing
Sengstaken Blakemore tube and inflating balloon
Step 5- Surgical methods to control PPH are many:- Ligation of uterine arteries Ligation of ovarian and uterine artery anastomosis Ligation of anterior division of internal iliac artery(unilateral or bilateral)
B-Lynch brace suture and haemostatic suturing
Angiographic arterial embolisation
Step 6- Hysterectomy
TRAUMATIC POST PARTUM HEMORRHAGE The trauma to perineum, vagina and the cervix is to be searched under good light by speculum examination and haemostasis is achieved by appropriate catgut sutures. The repair is done under general anesthesia .
TRAUMATIC POST PARTUM HEMORRHAGE
Secondary Post- Partum hemorrhage Any sudden loss of blood from the genital tract after the first 24 hrs postpartum and within 6 weeks of delivery. It is most likely to occur between 8 th and 14 th day after delivery
CAUSES
Caesarean section wound
Infection and separation of slough over a deep cervico-vaginal laceration.
Retained bits of cotyledon or membranes.
Endometritis and Subinvolution.
Withdrawal bleeding following estrogen therapy
Carcinoma cervix
Uterine inversion
Others-epithelioma, placental polyp, infected fibroid or fibroid polyp,.
CLINICAL FEATURES Lochia are heavier than normal Bright red loss Offensive if infection occurs Subinvolution of uterus Pyrexia and tachycardia Anemia
DIAGNOSIS Clinical features Laboratory examinations Ultrasonography
MANAGEMENT PRINCIPLES To assess the amount of blood loss and to replace the lost blood. To find out the cause and to take appropriate steps to rectify it. SUPPORTIVE THERAPY Blood transfusion, if necessary To administer ergometrine 0.5mg IM To administer antibiotics
CONSERVATIVE Careful watch for 24 hrs in hospital if bleeding is slight and no apparent cause is detected. ACTIVE TREATMENT Do not ignore small amount of bleeding. Remove the products by ovum forceps General curettage is done by using flushing curette. Ergometrine 0.5mg is given IM. Materials removed are to be sent for histological examination
Presence of bleeding from the sloughing wound of cervico-vaginal canal should be controlled by haemostatic sutures. May require laparotomy. Ligation of internal iliac artery. Hysterectomy
NURSING MANAGEMENT
NURSING ASSESSMENT Maternal history for risk factors. Evaluate for presence of clots expelled during voiding. Vital signs periodically Pulse pressure Intake and output Location and firmness of uterine fundus Palpate and percuss for bladder distension
Inspect for intactness of any perineal repair Breath sounds for signs of pulmonary edema Abdominal girth Effective hemostasis
NURSING DIAGNOSES Deficient fluid volume related to blood loss Anxiety related to unexpected blood loss and uncertainty of outcome Risk for infection related to blood loss and vaginal examination
PATIENT EDUCATION Educate about cause of hemorrhage. Importance of eating a balanced diet and taking vitamin supplements. Advise the women regarding feeling of tiredness and fatigue and to schedule daily rest periods. Sign and symptoms of hemorrhage for homecare. Ensure she has emergency numbers readily available. Follow up.
RECENT ADVANCEMENTS Prophylactic oxytocics reduce the risk of PPH by about 60% and the need for extra oxytocics by about 70%. O’Brien et al reported in a pilot study that Misoprostol 1000 μ g given rectally is an effective intervention in women with sever PPH unresponsive to standard uterotonic agents. The latter trials also concluded that Misoprostol is more effective than a combination of IM Syntometrine injection and Oxytocin infusion.
A recent survey from Norway has shown that 20% of obstetricians now use Misoprostol in the treatment of PPH. This is despite the fact that, until recently, no pharmacokinetic study had shown that Misoprostol is absorbed from the rectum. Within the last decade there has been renewed interest in new uterine tamponade procedures such as balloon compression and other procedures e.g. B- Lynch suture.
The easy-to-use, injection-ready format of Uniject ensures an accurate dose of Oxytocin in a nonreusable, sterile injection system with minimal preparation and minimum waste. The features and benefits of Oxytocin in Uniject will help programs launch innovative approaches to expand prevention and treatment of postpartum hemorrhage such as: Administration by skilled midwives, auxiliary nurses, or other trained lay providers. Use in areas of limited health facility infrastructure and/or health worker shortages. Overcoming acceptability concerns, including fear of injections, and safety concerns, regarding reuse of needles.
Uniject Oxytocin injection
CONCLUSION PPH is an Important cause of maternal morbidity. We now have new pharmacological and technical developments for prevention and treatment which can greatly reduce its incidence and sequelae. Wider use of thermostable prostaglandins like Misoprostol and dissemination of knowledge about new tamponade procedures can minimize its incidence and limit its serious sequelae.
The safety of the third stage of labour, and the incidence of PPH and its complications will remain linked however to the wider issues of reproductive health in general and more specifically to the funding and training needed to raise the standard of care offered to women in labour in many parts of the world.
