New Innovations In PPH Care
In the past 20 years, a set of cost-effective interventions, suitable for implementation at both health center and hospital level, has been developed. Some of these can also be used in the community or at home. We thus have another set of tools to control moderate and severe PPH. The use of these tools is also increasingly being combined in a standardized and simplified approach, summarized in the last bullet below.
Misoprostol is a fairly new drug, that among other uses also is an effective uterotonic.
Misoprostol tablets have been shown to be effective for routine use at home, to be taken by the new mother herself. As they are handed out at ANC visits in the last trimester, the pregnant woman is advised to take them after giving birth at home, if she cannot make it to the facility in time.
She is advised either to take them immediately after the birth of the placenta, or take them in case of big bleeding after birth.
The NASG is a garment made of neoprene, that is strapped to the legs and lower abdomen, tightened by Velcro strips, in the treatment of shock and bleeding.
Numerous studies have shown it to be effective in saving mothers’ lives by treating severe PPH. Long case series show that of women with severe PPH, 80-90% of women will be saved by correct use of the NASG. The garment can be ordered for around 40 USD (for instance from Maternova), and it has a life span of over 10 years in which it can be used over a hundred times.
Heat-stable carbetocin is an injectable drug that can replace oxytocin for prevention of PPH. It is thus used for AMTSL (active management of third stage of labor), and it is thus being introduced in some countries to be used routinely at all births. The price is going to be the same as the price of oxytocin. This will avoid the problem of only having oxytocin of varying quality for AMTSL, and often also ineffective by not having been stored in a cold chain.
So far, heat-stable carbetocin has not been proven effective for treatment of PPH, nor for induction/augmentation. This means that for years to come, oxytocin still needs to be available in the delivery room, side by side with heat-stable carbetocin.
Tranexamic acid, TXA, is a drug that helps the blood coagulate faster, by inhibiting the normal clot dissolution mechanism in the body. We know that when given IV to women with PPH, as soon as possible after the diagnosis of big bleeding, maternal mortality is 30% lower than if no TXA is given. No side reactions have been reported from big studies. It is essential that this fairly cheap drug is being made routinely available at all health facilities in the world where babies are born.
ESM - UBT
Intrauterine balloon tamponade was invented in the 1980s, and many devices have since been suggested and produced – from pricey, disposable devices used in high income countries, to condom catheters improvised locally. Today, two prepackaged and disposable low-cost devices have been developed, extensively tested and certified.
One is the Ellavi device produced by Sinapi, with a cost around 10-12 USD, and the other is the Every Second Matters UBT (ESM-UBT) with a price around 3 USD. The Sinapi device is industrially made, while ESM-UBT is assembled from existing components. Extensive studies of ESM-UBT shows that it can save over 95% of PPH mothers who are in shock.
External aortic compression is an emergency maneuver proposed to reduce postpartum hemorrhage and permit time for resuscitation and control of bleeding.
Although aortic compression generally is not taught to obstetricians as a maneuver to control major pelvic hemorrhage, anesthesiologists are aware of its value and may ask you to initiate this maneuver in the setting of severe postpartum hemorrhage.
It is recommended that external aortic compression be considered in severe life-threatening postpartum hemorrhage, particularly during stabilization or transport of the patient. This simple maneuver may be used as an adjunct to other measures and could prove of benefit, especially in locations or situations where advanced medical assistance is geographically or temporally removed.
Uterine compression sutures are a medical procedure used to assist in the treatment of PPH, and specifically with the goal of avoiding a hysterectomy, which can be a last-resort treatment for PPH.
There are a variety of compression sutures deployed in the field, such as the B-Lynch, Hayman, and Pereira sutures. All three of these uterine compression sutures are effective at treating postpartum hemorrhage caused by uterine atony.
Compression sutures have been reported as an effective method in treating PPH and thus avoiding hysterectomy. However, the reported experience with this method is limited.
Suturing Internal Iliac Artery
The internal iliac artery is the main vascular supply of pelvic visceral structures. All pelvic surgeons must know the anatomic landmarks and basic steps of internal iliac artery ligation in order to stop massive pelvic hemorrhage.
Ligation of the IIA has a proven success rate in controlling massive pelvic hemorrhage, varying between 40% and 100%, and obstetric pathologies occupy the first place as the leading factor.
The risk of operative injury beyond success is the major gap beneath the feasibility of the procedure. A detailed knowledge of the anatomy is required along with good exposure to achieve the procedure with the maneuver of traction and counter-traction. Bilateral ligation of the IIA is better to control the total blood flow in the pelvis and the surgeon would prefer to change the operative side for a comfortable surgical practice.
