Session Objectives By end of the session, participants will be able to: Identify Uterotonic Drugs used for AMTSL Advantages and disadvantages Stability in Tropical Climates Describe aspects related to Selection Storage Use and dosage

3 Uterotonic drugs used for AMTSL
Oxytocin- posterior pituitary extract Ergometrine- preparation of ergot Syntometrine- combination of oxytocin and ergometrine Misoprostol- prostaglandin E1 analogue Misoprostol holds promise for use as an uterotonic. It is effective, practical and inexpensive. In contrast to the other three uterotonics, misoprostol is stable (heat, light) and does not have to be given by injection. It can be given orally or rectally.

4 Oxytocin Advantages Acts within 2.5 minutes when given IM
Generally does not cause side effects Does not have any contraindications for postpartum use Is more stable than ergometrine when exposed to heat and light Disadvantages More expensive than ergometrine IM or IV preparations only Not heat stable Dosage for AMTSL 10 IU IM or 5 IU IV slow push

5 Ergometrine Advantages Low price Effect lasts 2–4 hours Disadvantages
Takes 6–7 minutes to become effective when given IM; oral form insufficiently effective Causes tonic uterine contraction Increased risk of hypertension, vomiting, headache Contraindicated in women with hypertension or heart disease Not stable when exposed to heat, light, or freezing Dosage for AMTSL 0.2 mg IM

6 Oxytocin vs Ergometrine
Results of trials do not show a difference in outcomes related to blood loss and transfusion between lower doses of oxytocin and the recommended dose of ergometrine A lower rate of manual removal of placenta was seen in women treated with oxytocin Ergometrine is associated with more adverse effects, especially with regard to causing high blood pressure

7 Recommendation: Oxytocin vs Ergometrine
In the context of active management of the third stage of labor, if all injectable uterotonic drugs are available: Skilled attendants should offer oxytocin to all women for prevention of PPH in preference to ergometrine/methylergometrine to women without hypertension or heart disease for prevention of PPH.

8 Uterotonic Drugs: Syntometrine
Advantages Combined effect of rapid action of oxytocin and sustained action of ergometrine Disadvantages More expensive than oxytocin or ergometrine alone Same disadvantages as ergometrine: Causes tonic uterine contraction Increased risk of hypertension, vomiting, headache Contraindicated in women with hypertension or heart disease Not stable when exposed to heat, light, or freezing Dosage for AMTSL 1 mL IM (ergometrine 0.5 mg + oxytocin 5 IU)

9 Oxytocin vs. Syntometrine: Results
Syntometrine was associated with a small reduction in risk of PPH < 1000 mL (OR 0.74, 95% CI ) Adverse effects of vomiting and hypertension were associated with the use of syntometrine There were no differences in other maternal or neonatal outcomes Conclusion Need to weigh benefit of reduction in risk of PPH with risk of other adverse effects associated with syntometrine McDonald, Prendiville and Elbourne 2000.

10 Recommendation: Oxytocin vs Syntometrine
In the context of active management of the third stage of labor, if all injectable uterotonic drugs are available: Skilled attendants should offer oxytocin to all women for prevention of PPH in preference to the fixed drug combination of oxytocin and ergometrine to women without hypertension or heart disease for prevention of PPH.

11 Uterotonic Drugs: Misoprostol
Advantages Effect lasts 75 minutes Can be stored at room temperature but should be protected from humidity Does not require injection skill or infection prevention measures required for giving an injection Can be distributed at the community level Disadvantages Acts within 6 minutes. Common side effects: shivering and elevated temperature Dosage for AMTSL 600 mcg po

12 Oxytocin vs. Misoprostol: Conclusion
Oral misoprostol is not as effective as oxytocin when used for prevention of PPH HOWEVER Oral misoprostol: is easy to administer has no known contraindications for use in the postpartum can be stored easily at room temperature (it is thermostable and light stable) does not require specific conditions for transfer has a shelf life of several years

13 Oxytocin vs. Misoprostol: Recommendations
In the context of active management of the third stage of labor: Skilled attendants should offer oxytocin for prevention of PPH in preference to oral misoprostol (600 mcg). In situations where oxytocin is not available or birth attendants’ skills are limited: administer misoprostol 600 mcg by mouth soon after the birth of the baby to reduce the occurrence of hemorrhage In the absence of active management of the third stage of labor, a uterotonic drug (oxytocin or misoprostol) should be offered by a health worker trained in its use for prevention of PPH.

14 Nipple Stimulation Nipple stimulation has not been shown to reduce risk of PPH Randomized controlled trial of suckling immediately after birth with over 4,000 subjects in Malawi showed no significant difference in frequency of PPH, mean blood loss or retained placenta Advantages of early breastfeeding and nipple stimulation: Stimulates natural production of oxytocin May maintain tone of contracted uterus Benefits baby Conclusions: When uterotonics are not available, use nipple stimulation and perform fundal massage after delivery of the placenta When uterotonics are not available, CCT should NOT be performed even with nipple stimulation Need uterotonics; efforts should be made to make it available at all levels of care. Getting the uterus to contract probably requires some “surge” of oxytocin, such as that delivered by an injection of oxytocin. When uterotonics are not available, CCT and fundal massage should be performed. Natural oxytocin produced by suckling of baby at breast may be useful for helping to maintain the tone of an already contracted uterus. Bullough, Msuku and Karonde 1989.

15 Stability of Injectable Uterotonics in Tropical Climates: Objective and Design
To determine pattern of stability in long term dark storage, short term exposure to high temperature and light To develop guidelines Methods: Tested field samples of ergometrine and methylergometrine and also simulated field storage conditions at different temperature/light exposure WHO 1993.

16 Stability of Injectable Uterotonics in Tropical Climates: Results
Field: Ergometrine: only 31% of samples had compliant level of active ingredient Oxytocin: one expired, 5 samples had 104–142% of stated amount of active ingredient WHO 1993.

17 Stability of Injectable Uterotonics in Tropical Climates: Results (continued)
Simulation condition Ergometrine/ methylergometrine Oxytocin Refrigeration for 12 months Lost 4-5% active ingredient No loss 30oC, dark Lost 25% Lost 14% 21–25oC, light Lost 21–27% in one month >90% in 12 months Lost 5% 40oC dark Lost > 50% Lost 80% WHO 1993.

18 Stability of Injectable uterotonics in Tropical Climates: Conclusions
Stability of oxytocin is better than ergometrine/ methylergometrine, especially regarding light Carefully read the manufacturer’s recommendations for storage of injectable uterotonics – where possible, store uterotonics in refrigerator (2–8ºC) and away from light Remove injectable uterotonics from box only for immediate use Short periods unrefrigerated are fine (1 month at 30°C) uterotonics are not heat stable, but oxytocin is better than ergometrine/methyl-ergometrine. WHO 1993.

19 Storage of uterotonic drugs - In the Pharmacy
Make sure that there are adequate stocks of uterotonic drugs, syringes, and injection safety materials Check manufacturer’s label for storage recommendations Follow the rule of first expired – first out (or first in – first out) to reduce wastage of uterotonic drugs If possible, keep injectable uterotonics refrigerated at 2–8°C Store misoprostol at room temperature and away from excess heat and moisture Protect ergometrine and syntometrine from freezing and light. Make sure that there is a system in place to monitor the temperature of the refrigerator / cold box

20 Storage of uterotonic drugs In Delivery Rooms
Check manufacturer’s label for storage recommendations Periodically remove ample amount of injectable uterotonics needed for expected client load from refrigerator Avoid storage of injectable uterotonics in open kidney dishes, trays, or coat pockets Store oxytocin outside the refrigerator at a maximum of 30°C (warm, ambient climate) for up to three months Store misoprostol at room temperature away from excess heat and moisture Store ergometrine and syntometrine vials outside the refrigerator in closed boxes and protected from the light for up to one month at 30°C

21 Recommendations Concerning Selection of Uterotonic for AMTSL
Oxytocin is the uterotonic of choice for AMTSL If oxytocin is not available, use syntometrine or ergometrine If injectable uterotonic drugs are not available, use misoprostol 600 mcg by mouth Remember: Do not use ergometrine or syntometrine in women with hypertension or heart disease

22 Recommendations concerning management of the third stage of labor in the absence of an SBA
In situations where birth attendants’ skills are limited: administer misoprostol 600 mcg by mouth soon after the birth of the baby to reduce the occurrence of hemorrhage use nipple stimulation do not perform CCT perform uterine massage after delivery of the placenta

23 Summary Oxytocin is the uterotonic of choice for AMTSL
If oxytocin is not available, give ergometrine or syntometrine for AMTSL If injectable uterotonics are not available, give oral misoprostol for AMTSL If birth is not attended by an SBA, give oral misoprostol soon after birth of the baby to reduce PPH Ensure the adequate storage and supply of uterotonic drugs
