| #### **1. Introduction** | |
| The aim of this guideline is to provide evidence-based | |
| recommendations in the management of primary | |
| postpartum haemorrhage (PPH). This is the commonest direct cause of maternal death globally and in | |
| Sri Lanka. The objective of this guideline is to ensure | |
| anticipation, prevention, early detection and timely and | |
| appropriate management of PPH. | |
| #### **2. Definition** | |
| For the purpose of this guideline PPH is defined as | |
| blood loss of 500 ml or more from the genital tract | |
| within 24 hours of the birth of a baby. Blood loss of | |
| over 1000 ml is defined as major PPH. Major can be | |
| further sub-divided into moderate (1001-2000 ml) and | |
| severe >2000 ml. | |
| In a woman with lower body mass (e.g. <60 Kg) a | |
| lower level of loss of blood volume may be clinically | |
| significant. | |
| Since blood volume differs between persons, | |
| blood loss must be individualized. | |
| The loss of 40% or more of the blood volume is life | |
| threatening and will be defined as a massive | |
| obstetric haemorrhage. Blood volume = 100ml/Kg | |
| Irrespective of the loss of blood volume, appearance | |
| of cardiovascular instability (i.e. tachypnea, altered | |
| mental status, tachycardia and hypotension) signifies | |
| possibility of major obstetric hemorrhage. | |
| #### **3. Prevention of Postpartum** **Haemorrhage** | |
| Active management of the third stage of labour is the | |
| cornerstone of prevention of primary PPH. | |
| Postpartum care observations should be recorded on | |
| a MEOWS chart for early detection of patients needing | |
| further care. | |
| _**Minimizing risk:**_ | |
| - Anemia in pregnancy should be corrected during | |
| antenatal period. Patients who are decided for | |
| delivery advise to have minimum level of | |
| haemoglobin of 10 g/dL. | |
| - Maintain adequate hydration during labor in | |
| order to have physiological maximum | |
| circulatory volume. | |
| PPH occurs most often in women without risk | |
| factors. Therefore, the blood group and level of | |
| haemoglobin of every woman who goes into labor must | |
| be known. | |

| #### SLCOG Guideline | |
| Women with known risk factors associated with PPH, | |
| as listed in Box 1. Should be advised to deliver in a | |
| specialist obstetric unit under extra vigilance. Of these, | |
| Abruptio placenta, Placenta praevia and Morbidly | |
| adherent placentae are especially at higher risk. | |
| **Good practices:** | |
| - All women under-going labor preferably should | |
| have a large bore cannula. | |
| - Any woman with at least one risk factor should | |
| have intravenous access established with either | |
| a 16 or Gray cannula and a sample of blood | |
| taken and preserved for grouping and DT and | |
| or save. | |
| - Attempt to estimate and record blood loss in all | |
| deliveries. | |
| - Check the state of the uterine fundus as a routine | |
| post-delivery observation practice. | |
| #### **4. Management of Primary PPH** | |
| In Sri Lanka usual practice has been to commence | |
| treatment when there is continuing bleeding despite | |
| uterine massage irrespective of the amount of blood | |
| lost. | |
| _**It is recommended that this practice be continued.**_ | |
| 4.1. **Identification of severity of haemorrhage** | |
| Clinicians should be aware that the visual estimation | |
| of post partum blood loss is inaccurate and that clinical | |
| signs and symptoms should be included in the | |
| assessment of PPH. | |
| Shock index (SI)- (Heart rate/Systolic Blood Pressure) | |
| as an effective predictor for PPH SI <0.9 provides | |
| reassurance, whereas SI ≥1.7 indicates a need for | |
| urgent attention in haemorrhage. (BJOG. 2015; 122(2): | |
| 268-75. doi: 10.1111/1471-0528.13206.) | |
| Call for help: | |
| Who should be informed when the woman presents | |
| with PPH? | |
| - **Early involvement of appropriate senior** | |
| **staff is fundamental to the management of** | |
| **PPH.** | |
| **•** **Any significant postpartum bleeding should** | |
| **be informed to the highest level of obstetric** | |
| **team. This should be done by the attending** | |
| **Medical Officer.** | |
| **•** **However, in the absence of a MO any staff** | |
| **member could inform.** | |
| **•** **Even the situation is manageable by middle** | |
| **grade medical staff information to the** | |
| **highest level is essential.** | |
| **•** **In minor PPH, the first line staff should be** | |
| **alerted.** | |
| **•** **In major PPH, the following members** | |
| **should be alerted at the same time with** | |
| **effective communication.** | |
| a. The obstetric middle grade, | |
| b. The anesthetic middle grade; Where available, | |
| the early involvement of the anesthetic team, | |
| even while the patient is still in the labor room | |
| is recommended. | |
| c. Inform theatre | |
| d. Alert MO blood bank | |
| e. Alert Consultant Obstetrician | |
| f. Alert Consultant Anaesthetist | |
| g. Transfusion medicine specialist / | |
| Haematologist | |
| h. Alert the head of the institution | |
| **128** _Sri Lanka Journal of Obstetrics and Gynaecology_ | |
| In a hospital clear instruction to telephone operator | |
| how to convey such message should be given by the | |
| administration to alert the stipulated staff as stated | |
| above. The telephone operator should document the | |
| list of staff informed and submit it to the ward to be | |
| attached to the Bed Head Ticket. | |
| **Communication with the mother** | |
| Maintain a calm atmosphere. | |
| Keep the mother (and labor companion/family) | |
| informed and reassure the mother regularly where | |
| feasible. | |
| 4.2. **Documentation: It is important to record:** | |
| **to be done later once the mother is stable** | |
| - The staff attended and the time the sequence of | |
| events. | |
| - The details of interventions, administration of | |
| pharmacological agents, fluid and blood products | |
| given, surgical interventions. | |
| - The condition of the mother throughout the | |
| different steps. | |
| - It is recommended that one member of staff is | |
| delegated specifically for this task and to | |
| coordinate with other relevant disciplines. | |
| 4.2.1. **Measures for minor PPH: Blood loss** | |
| **500-1000ml without clinical shock** | |
| - Assess, monitor and record: general condition, | |
| estimated blood loss, pulse, blood pressure and | |
| respiratory rate (every 15 minutes) | |
| - Ensure there is intravenous access with a wide | |
| (14-16 G) bore cannulae. | |
| - Send blood for cross matching and baseline full | |
| blood count. | |
| - Start Ringer’s lactate (Hartmann’s)/ Normal | |
| saline. | |
| - Identify the cause of bleeding. | |
| - Keep the woman warm. | |
| - Pay attention to the temperature of labor room, | |
| operating theatre, intravenous fluids, blood, | |
| blood products and fluids used for lavage. | |
| Hypothermia is known to promote coagulopathy. | |
| - Maintain MEOWS chart. | |
| #### SLCOG Guideline | |
| 4.2.2. **PPH of more than blood loss 1000ml/** | |
| **active bleeding/ signs of shock** | |
| - Recognize this as a life-threatening emergency. | |
| Quick action without delay saves life. | |
| - Major PPH once suspected should be managed | |
| in adequately equipped operating theatre with | |
| all resuscitation facilities. | |
| - Early involvement of appropriate senior staff is | |
| fundamental for the management of major PPH. | |
| Following members of staff should be called | |
| and summoned to attend. Theatre in charge | |
| Nursing officer, Consultant Obstetrician, | |
| Consultant Anaesthetist, Consultant Transfusion | |
| specialist, Consultant Haematologist, Overseer | |
| of minor staff. | |
| - Team work, Resuscitation, Monitoring, | |
| Controlling bleeding pharmacologically and | |
| surgically, taking general measures, all should | |
| go hand in hand because all are equally | |
| important. | |
| - Attempts must be made to prevent or minimize | |
| dilutional coagulopathy, hypothermia, and | |
| metabolic acidosis from the beginning of | |
| resuscitation protocol. | |
| #### **Resuscitation** | |
| - ABCDE approach. | |
| - Clear airway. High flow oxygen to keep SPO2> | |
| 95%, attach oximeter probe. | |
| - Intubate, ventilate – if abnormal breathing, | |
| unconscious, unresponsive. | |
| - Insert two 14-16 g cannulae, draw 20 ml blood | |
| for grouping, DT, FBC, BU, Electrolytes, | |
| APTT, PT/INR, ROTEM, S. Fibrinogen. | |
| - Request 6 U blood, Cryoprecipitate 20 U, FFP | |
| 4 U, platelets 1 adult dose. | |
| - Inform blood bank to activate massive haemor | |
| rhage protocol. | |
| - Monitor BP, ECG, AVPU, CBS, UOP, CVP | |
| - Transfuse blood as soon as possible. Minimise | |
| crystalloid, replace blood loss with blood. In | |
| emergency use on the availability of specific | |
| _Vol. 44, No. 2, June 2022_ **129** | |
| #### SLCOG Guideline | |
| blood. O-ve O+ve group-specific uncross | |
| matched cross-matched. | |
| - Warm patient with forced air warmer, Warm | |
| fluids/blood using rapid warmer infuser. Or | |
| normal blood warmer. | |
| - Control bleeding- medical/ physical manoeuvres | |
| and surgical. | |
| - Get ROTEM result within 5-10 min. Replace as | |
| indicated by ROTEM. | |
| - If ROTEM not available start giving shock | |
| packs – 4:4: I adult dose of platelets. | |
| - Due consideration must be given to keeping | |
| transport facilities available to obtain blood and | |
| blood products from another institution. | |
| **130** _Sri Lanka Journal of Obstetrics and Gynaecology_ | |
| 4.5.1. **Establish a cause for the bleeding – Four** | |
| **T’s, Tone, Tissue, Trauma, Thrombin** | |
| 4.5.3.1. **Management of Atonic Haemorrhage** | |
| - Start uterine massage by ‘rubbing up the fundus’. | |
| - Clear the cervical canal and vagina of blood clots | |
| by vaginal examination. | |
| - Hypothermia is a particular risk in the theatre | |
| environment. Measures must be taken to | |
| minimize the loss of heat from the woman. | |
| - Cochrane review 25 [th] April 2018 conclude | |
| Ergometrine plus Oxytocin combination, | |
| misoprostol plus oxytocin combination is more | |
| effective in preventing PPH [500ml than using | |
| current standard of Oxytocin alone. | |
| - Administer either Ergometrine maleate 0.5 mg | |
| slow IV or methyl Ergometrine 0.2 mg slow IV | |
| or oxytocin 5 IU IV and start an infusion of 40 | |
| IU of Oxytocin in 500 ml of Hartmann’s / | |
| Normal Saline solution at 125 ml per hour via | |
| an infusion pump. | |
| - Ergometrine can be repeated in every 2 hours | |
| up to 3 doses. | |
| - Start bimanual compression of uterus. | |
| - If the bleeding fails to abate completely in 5-10 | |
| minutes administer/repeat Ergometrine 0.5mg | |
| IV. (Level IV – SLCOG consensus) (WHO 2000 | |
| publication Managing Complications in | |
| Pregnancy and Child Birth Page 5-28, Table 1, | |
| Can repeat Ergometrine for the first time in 15 | |
| Minutes up to four doses thereafter in four hours | |
| apart.). | |
| - At the same time, administer Tranexamic acid | |
| 1 g by slow IV over 10 minutes. Maximum | |
| benefit is achieved if given within 30 minutes. | |
| This dose may be repeated after 30 minutes if | |
| necessary and later if bleeding recommences. | |
| - If the bleeding fails to abate completely in a | |
| further 10 minutes administer misoprostol | |
| 1000mic per rectally or sublingually. | |
| - If the bleeding fails to abate completely for | |
| above measures proceed to uterine balloon | |
| tamponade. Compression of Aorta just above | |
| the bifurcation helps to minimize the loss until | |
| other measures are readily available. | |
| #### SLCOG Guideline | |
| - For details of the method of balloon tamponade. | |
| Bakri Catheter. | |
| - Any institution undertaking delivery of pregnant | |
| women should have members trained for | |
| insertion of tamponade catheter. | |
| **Before transferring the patient it’s important** | |
| **to do the following;** | |
| - Large bore cannula inserted and IV | |
| Crystalloids (NS/RL) or blood running | |
| - Oxygen 10-15L/ min to keep SpO2 > 95% | |
| - IV Tranexamic acid 1g given | |
| - Temporizing measures such as manual | |
| aortic compression and sand bags to | |
| compress the uterus are recommended | |
| while the patient is in transit | |
| - Inform the receiving institution/Ward / ICU | |
| - After the balloon is inserted and the vagina | |
| packed (to keep the balloon in the uterus), the | |
| woman’s vital parameters and the level of the | |
| fundus must be monitored carefully. Where | |
| these indicate the woman is continuing to bleed. | |
| - Prior to laparotomy the woman must be examined under anesthesia for tears in the genital | |
| tract. | |
| - The surgical measures would depend on the | |
| woman's condition. “Too little too late” is the | |
| main contributor to mortality in PPH. First hour | |
| known as the golden hour in decision making. | |
| Surgical measures include brace (compression) | |
| sutures, uterine de-vascularization, Haemostatic | |
| mattress sutures to bleeding sinusoids, Box | |
| sutures to include the bleeding lower segment | |
| in Placenta Previa, internal iliac ligation and | |
| Hysterectomy. | |
| - The “sandwich technique” involves inserting a | |
| balloon tamponade after the application of brace | |
| sutures. | |
| **Resort to hysterectomy without delay if other** | |
| **measures appear to be failing.** | |
| _Vol. 44, No. 2, June 2022_ **131** | |
| #### SLCOG Guideline | |
| 4.5.3.2. **Management of Traumatic PPH** | |
| **Manage only in theatre under suitable anaes-** | |
| **thesia and exposure** | |
| 1. Exclude high vaginal and cervical tears before | |
| suturing episiotomy. | |
| 2. Examine for paravaginal and broad ligament | |
| haematomata with a combined per vaginal and | |
| per rectal examination. | |
| 3. Early use of USS recommended for identification of internal bleeding. | |
| 4. Paravaginal hematomas of more than 5 cm | |
| diameter will usually require surgical evacuation. | |
| A bleeding point is usually present and must | |
| be looked for. In cases where it is difficult to | |
| control bleeding, a Foley catheter with its | |
| balloon inflated may be left in the cavity. Packing | |
| of the vagina may also be useful. | |
| 5. Cervical tears must be identified by systematic | |
| inspection of the cervix using Green- Armytage | |
| forceps and sutured. | |
| 6. In case of multiple tears with venous oozing, it | |
| may be better to insert a balloon catheter into | |
| the vagina or to pack the vagina with moistened | |
| vaginal packs than to try to suture all the tears. | |
| 7. Vasopressin soaked pack (1 vial: 200ml diluted | |
| saline). | |
| **Rupture of the uterus** | |
| - Rupture of the uterus must be suspected when | |
| the general condition is deteriorating out of | |
| proportion to the visible blood loss and there is | |
| continuing bleeding in the presence of a | |
| contracted uterus. | |
| - This is particularly so in a woman with a scarred | |
| uterus. | |
| 4.5.3.3. **Coagulopathy causing PPH** | |
| - This could be due to coagulopathy following | |
| Death in utero, Abruptio placentae, severe PreEclampsia, HELLP syndrome, Sepsis, Amniotic | |
| fluid embolism, Acute fatty liver, primary | |
| immune Thrombocytopenia, Von Willebrand’s | |
| disease etc. | |
| - It could also be due to suboptimal management | |
| of the PPH. | |
| - Early summoning of a Haematologist and | |
| Transfusion medicine specialist for management | |
| will be important in this situation. | |
| - Where available, Thromboelastometry should be | |
| used. | |
| **Special Situations** | |
| - Tranexamic acid 1 g IV can be given for high | |
| risk mothers who undergo caesarean section in | |
| addition to Syntocinon. | |
| - When there is placenta praevia after a previous | |
| caesarean section, it is advisable to look for | |
| specific USS features of accreta /percreta. | |
| - The timing and location for delivery should be | |
| chosen to facilitate consultant presence and | |
| access to intensive care and other supportive | |
| care. Eg Rapid transfusion facilities, availability | |
| of blood and blood products. | |
| - It is important to educate the relatives about the | |
| risks and the need for critical care post operatively and consent obtained. | |
| 4.5.4. **Debriefing** | |
| - It is possible that a major PPH could result in | |
| significant psychological morbidity. | |
| - This could be minimized by timely debriefing | |
| of the patient and her family, preferably by the | |
| Consultant. | |
| - This should be done immediately after the event, | |
| before discharge or at the postnatal visit or at | |
| any time as requested by her or the family. | |
