RESUMEN
STUDY OBJECTIVE: To evaluate the use of dilute carboprost tromethamine injection at the endometrium/myoma junction during hysteroscopy to facilitate myoma expulsion and removal in a single procedure. DESIGN: Case series. SETTING: Single high-volume academic medical center. PATIENTS: Seven patients aged 32 to 51 years old with FIGO type 2 uterine myomas and symptoms of abnormal uterine bleeding or infertility undergoing hysteroscopic resection with a morcellation device from November 2022 to July 2023. INTERVENTION: Dilute injection of carboprost tromethamine (10 µg/mL) at time of hysteroscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: The main outcome measure was ability to complete the hysteroscopic myomectomy in a single procedure using a hysteroscopic morcellator. Secondary outcomes included total operative time, fluid deficit, and postoperative pharmacologic side effects and/or surgical complications. Among our 7 patients, all had successful single procedure complete resections of myomas ranging from 0.9 to 4.6 cm in maximal diameter. Average operative time was 30 minutes, and average fluid deficit was approximately 839 mL. The carboprost dosages used ranged from 30 to 180 µg. One patient experienced prolonged postoperative nausea and vomiting that resolved with antiemetics. One patient experienced postoperative endometritis that improved with antibiotics. CONCLUSION: In this pilot study, injection of dilute carboprost intraoperatively facilitated one-step hysteroscopic myomectomy of FIGO 2 myomas, via enhanced extrusion of the intramural portion of the fibroid into the uterine cavity, with both short operative times and acceptable fluid deficits.

INTRODUCTION: Desmopressin (DDAVP) has been utilized clinically in patients taking aspirin (ASA) to improve drug-induced platelet dysfunction. Misoprostol and carboprost, prostaglandin analogs commonly used for postpartum hemorrhage, may also induce platelet aggregation. The aim of this study was to determine the effects of DDAVP, misoprostol, and carboprost administration on platelet aggregability following traumatic brain injury (TBI) in mice treated with ASA. METHODS: Male C57BL/6 mice were randomized into seven groups (n = 5 each): untouched, ASA only, Saline/TBI, ASA/TBI, ASA/TBI/DDAVP 0.4 µg/kg, ASA/TBI/misoprostol 1 mg/kg, and ASA/TBI/carboprost 100 µg/kg. TBI was induced via a weight drop model 4-h after ASA (50 mg/kg) gavage. Mice were given an intraperitoneal injection of DDAVP, misoprostol, or carboprost 10 minutes after TBI. In vivo testing was completed utilizing tail vein bleed. Mice were sacrificed 30-min posttreatment and blood was collected via cardiac puncture. Whole blood was analyzed via Multiplate impedance aggregometry, rotational thromboelastometry, and TEG6s. RESULTS: Mice receiving misoprostol after ASA/TBI demonstrated decreased tail vein bleeding times compared to ASA only treated mice. However, mice treated with misoprostol following ASA and TBI demonstrated decreased platelet aggregability compared to untouched mice and TBI only mice within the arachidonic acid agonist pathway. By contrast, DDAVP and carboprost did not significantly change platelet aggregability via adenosine diphosphate or arachidonic acid following ASA and TBI. However, DDAVP did decrease the platelet contribution to clot via rotational thromboelastometry. CONCLUSIONS: Reversal of medication-induced platelet inhibition has become increasingly controversial after TBI. Based on these results, DDAVP, misoprostol, nor carboprost consistently improve platelet aggregability following TBI in those also treated with ASA.

Prostaglandins and their receptors regulate various physiological processes. Carboprost, an analog of prostaglandin F2α and an agonist for the prostaglandin F2-alpha receptor (FP receptor), is clinically used to treat postpartum hemorrhage (PPH). However, off-target activation of closely related receptors such as the prostaglandin E receptor subtype EP3 (EP3 receptor) by carboprost results in side effects and limits the clinical application. Meanwhile, the FP receptor selective agonist latanoprost is not suitable to treat PPH due to its poor solubility and fast clearance. Here, we present two cryo-EM structures of the FP receptor bound to carboprost and latanoprost-FA (the free acid form of latanoprost) at 2.7 Å and 3.2 Å resolution, respectively. The structures reveal the molecular mechanism of FP receptor selectivity for both endogenous prostaglandins and clinical drugs, as well as the molecular mechanism of G protein coupling preference by the prostaglandin receptors. The structural information may guide the development of better prostaglandin drugs.

OBJECTIVES: Carboprost plays an important role in managing refractory uterine atony and severe postpartum hemorrhage. However, it is associated with challenging adverse reactions. We aimed to evaluate the clinical effects of low dose sufentanil on the prevention of adverse events associated with carboprost during cesarean delivery. MATERIAL AND METHODS: Patients were randomly divided into two groups: a placebo control group (group C, n = 15) that received an intravenous infusion of 1 mL of normal saline 2 min before carboprost and a sufentanil group (group S, n = 15) that received 5 µg of sufentanil. The primary outcome was the incidence of nausea and vomiting following carboprost administration. RESULTS: The incidence of nausea, vomiting, and gastrointestinal discomfort was significantly lower in group S than in group C (p < 0.05). CONCLUSIONS: The prophylactic use of low dose sufentanil reduces the incidence of gastrointestinal side effects caused by carboprost administration during cesarean section.

The study was carried out to observe the effect of combination drug therapy during cesarean section in preventing postpartum hemorrhage for women with hypertensive disorder complicating pregnancy (HDCP). The 180 women who had been treated in our hospital for HDCP were enrolled and randomly divided into observation group (sublingual administration of carboprost combined with oxytocin treatment (20IU oxytocin and small pot drip of 10IU oxytocin after delivery) and control group (1mg of carboprost when the fetal head came out and then applied with intramuscular injection of 20IU oxytocin), each containing 90. The comparison of postpartum hemorrhage situation between two groups was carried out. Compared with control group, the observation group had significantly lower intraoperative blood loss and postoperative 1h blood loss, p<0.0, but similar postoperative 2-24h blood loss, p>0.05; in observation, there were 6 cases of postpartum hemorrhage, while the number in control group was 20 cases. The two groups had no difference in blood pressure after treatment, p>0.05.The combination drug therapy during cesarean section is effective and reliable in preventing postpartum hemorrhage for women with HDCP.

Background: Carboprost tromethamine injection has a high safety factor in clinical application and has a good effect on uterine smooth muscle and vasoconstriction. Carboprost aminobutyriol combined with oxytocin may be beneficial to infant outcome and uterine involution after cesarean section. Objective: To investigate the effects of carboprost tromethamine combined with oxytocin on infant outcome, postpartum hemorrhage, and uterine involution in parturients undergoing cesarean section. Methods: A total of 120 parturients undergone cesarean section in our hospital from February 2019 to April 2021 were selected as the object of study. The parturients were randomly divided into control group (n = 60) and research group (n = 60). The control group was treated with oxytocin, and the research group was treated with carboprost aminobutyriol combined with oxytocin. The amount of maternal bleeding, uterine floor decline index, the end of lochia, poor rate of uterine involution, infant outcome, and the incidence of adverse drug reactions were compared between the two groups. Results: The amount of bleeding in the research group was significantly lower than that in the control group (P < 0.05). The position of the last uterine floor and the index of uterine floor downward movement in the research group were significantly higher than those in the control group (P < 0.05). The disappearance time of bloody lochia and serous lochia in the research group was significantly shorter than that in the control group (P < 0.05). The end time of lochia in the research group was higher than that in the control group, and the rate of uterine involution in the research group was lower than that in the control group (P < 0.05). The neonatal weight and Apgar score in the research group were higher than those in the control group, and the hospitalization rate of neonatal ICU in the research group was significantly lower than that in the control group. The incidence of adverse reactions in the research group was significantly lower than that in the control group (P < 0.05). Conclusion: Carboprost aminobutyriol combined with carbestatin can effectively prevent the occurrence of bleeding after cesarean section, improve uterine involution, and improve neonatal birth quality, which is worth popularizing.

BACKGROUND: Estrogen has been usually used in clinic for medical pretreatment of early pregnancy loss. There was little reported the effect of estrogen combined with prostaglandin analogs in the medical management of early pregnancy loss. This retrospective study aimed to evaluate the efficacy of estrogen pretreatment for medical management of early pregnancy loss and explore the confounding factor of intrauterine adhesion (IUA) on the outcome of medical management. METHODS: A total of 226 early pregnancy loss patients who received pretreatment with estradiol valerate and/or mifepristone, followed by carboprost methylate suppositories (study groups), or carboprost methylate suppositories alone (control group) in a regional central institution from March 2020 to February 2021 were retrospectively studied. All patients were evaluated by hysteroscopy 6 h after carboprost methylate suppositories use to assess whether the gestational sac was complete expulsion and assess the morphology of uterine cavity. RESULTS: The complete expulsion rate was 56.94% in the mifepristone and estradiol valerate-pretreatment group, 20.69% in the estradiol valerate-pretreatment group, 62.5% in the mifepristone-pretreatment group, and 12.5% in the control group. Compared with the control group, pretreatment with estradiol valerate did not increase the complete expulsion rate significantly (P = 0.297), pretreatment with mifepristone increased the complete expulsion rate significantly (P < 0.001). Pretreatment with mifepristone combined with estradiol valerate did not increase the complete expulsion rate significantly comparing with pretreatment with mifepristone (P = 0.222). The data of IUA showed that the complete expulsion rate in patients with IUA was lower than that in those patients without IUA (P < 0.001). CONCLUSIONS: Pretreatment with estrogen was not a sensible substitute for mifepristone in the medical management of early pregnancy loss. Mifepristone followed by carboprost methylate suppositories was likelihood of the ideal medical scheme in early pregnancy loss. IUA decreased the complete expulsion rate of medical management, it is cautious about medical management for early pregnancy loss with risk of IUA. TRIAL REGISTRATION NUMBER: ChiCTR2100046503.

BACKGROUND: Postpartum hemorrhage causes a quarter of global maternal deaths. The World Health Organization recommends oxytocin as the first line agent to prevent hemorrhage during cesarean delivery. However, some randomized controlled trials suggest that other uterotonics are superior. OBJECTIVE: We conducted a network meta-analysis comparing the ability of pharmacologic agents to reduce blood loss and minimize the need for additional uterotonics during cesarean delivery. DATA SOURCES: We searched the Cochrane Central Register of Controlled Trials, Embase, and MEDLINE databases from inception to May 2020. STUDY ELIGIBILITY CRITERIA: We included randomized controlled trials that compared oxytocin, carbetocin, misoprostol, ergometrine, carboprost, or combinations of these in the prevention of postpartum hemorrhage during cesarean delivery. METHODS: We performed a systematic review followed by an NMA in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Quality of the evidence was assessed with the Confidence in Network Meta-Analysis approach and Grading of Recommendations, Assessment, Development and Evaluations tool within the summary of findings table. Our primary outcomes were the estimated blood loss and need for additional uterotonics. Secondary outcomes included nausea and postpartum hemorrhage of >1000 mL. We performed sensitivity analyses to explore the influence of surgical context and oxytocin administration strategy. RESULTS: A total of 46 studies with 7368 participants were included. Of those, 21 trials (6 agents and 3665 participants) formed the "estimated blood loss" network and, considering the treatment effects, certainty in the evidence, and surface under the cumulative ranking curve scores, carbetocin was assessed to probably be superior to oxytocin, but only in reducing the estimated blood loss by a clinically insignificant volume (54.83 mL; 95% confidence interval, 26.48-143.78). Misoprostol, ergometrine, and the combination of oxytocin and ergometrine were assessed to probably be inferior, whereas the combination of oxytocin and misoprostol was assessed to definitely be inferior to oxytocin. A total of 37 trials (8 agents and 6193 participants) formed the "additional uterotonic" network and, again, carbetocin was assessed to probably be superior to oxytocin, requiring additional uterotonics 185 (95% confidence interval, 130-218) fewer times per 1000 cases. Oxytocin plus misoprostol, oxytocin plus ergometrine, and misoprostol were assessed to probably be inferior, whereas carboprost, ergometrine, and the placebo were definitely inferior to oxytocin. For both primary outcomes, oxytocin administration strategies had a higher probability of being the best uterotonic, if initiated as a bolus. CONCLUSION: Carbetocin is probably the most effective agent in reducing blood loss and the need for additional uterotonics. Oxytocin appears to be more effective when initiated as a bolus.

OBJECTIVE: To investigate whether continuous infusion of propofol at a subhypnotic dose prevents nausea and vomiting following carboprost administration at cesarean delivery. METHODS: A prospective, randomized, double-blind, placebo-controlled trial conducted at West China Second University Hospital, from June 28, 2017 to January 30, 2018. Pregnant women were randomly allocated to propofol or saline infusion immediately before receiving carboprost at cesarean delivery under combined spinal-epidural (CSE) anesthesia. Propofol was given at an infusion rate of 1.0 mg/kg/h following a loading dose of 0.3 mg/kg. Primary outcome was incidence of intraoperative nausea and vomiting (IONV). Potential sedative effect of propofol infusion was assessed using Modified Observer's Assessment of Alertness and Sedation (MOAA/S) scoring and continuous Bispectral Index (BIS) monitoring. RESULTS: The incidence of IONV was lower in patients who received propofol compared with saline (46.7% vs 76.7%, OR 0.27; 95% CI, 0.092-0.78, P = 0.016 for nausea; 26.7% vs 53.3%, OR 0.50; 95% CI, 0.25-0.95, P = 0.032 for retching; 10.0% vs 50.0%, OR 0.11; 95% CI, 0.03-0.44, P < 0.001 for vomiting). There were no differences in MOAA/S scoring or BIS between the two groups. CONCLUSION: A subhypnotic dose of propofol reduces the incidence of nausea and vomiting following carboprost administration at cesarean delivery under CSE anesthesia, without measurable effect on patients' consciousness or alertness.

The study aims to explore the effect of low-frequency electric pulse technique combined with carboprost methylate suppositories on recovery of gastrointestinal function and postoperative complications of patients with scarred uterus undergoing secondary cesarean section (C-section). The clinical data of 120 patients with scarred uterus undergoing secondary C-section treated in our hospital from February 2019 to February 2020 were retrospectively analyzed, and the patients were equally divided into experimental and control groups according to their admission order, where each group included 60 patients. After the operation, patients in the control group received routine nursing and conducted breastfeeding, and carboprost methylate suppositories were used for postoperative hemostasis. Those in the experimental group received low-frequency electric pulse technique for comprehensive treatment to compare their coagulation function indicators, recovery of gastrointestinal function, incidence rates of postoperative complications, and involution of uterus. No significant between-group differences in patients' general information such as gestational weeks, gravidity, and number of times receiving C-section were observed (P > 0.05). Compared with the control group after the operation, patients in the experimental group obtained significantly better coagulation function indicators (P < 0.001) and presented better gastrointestinal function recovery (P < 0.001), significantly lower incidence rates of postpartum hemorrhage, retention of urine, deep venous thrombosis of lower limb, rupture of uterus, and endometrial cavity fluid (P < 0.05), and significantly better involution of uterus (P < 0.001). In conclusion, combining low-frequency electric pulse technique with carboprost methylate suppositories can lower the incidence rates of postoperative complications for patients with scarred uterus undergoing secondary C-section, improve their coagulation function, promote the recovery of gastrointestinal function, and present the desirable involution of uterus, which should be promoted in practice.

BACKGROUND: No well-designed and systematic evaluation of the efficacy and safety of leonurus japonicus injection (LJI) in combination with carboprost tromethamine has been found. Therefore, we undertook a meta-analysis to assess the efficacy and safety of carboprost tromethamine combined with LJI for the prevention of postpartum hemorrhage in high-risk pregnant women to provide new evidence-based medical evidence for clinical treatment. METHODS: This systematic review and meta-analysis would be performed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The following databases including EMBASE, MEDICINE, Wanfang, China National Knowledge Infrastructure database, and Cochrane central controlled trial registries were searched by 2 reviewers from inception to July 2021. Mesh and keyword search terms were "motherwort," "Yimucao," "leonurus japonicas," "carboprost tromethamine," and "postpartum hemorrhage." Any cohort studies that assessed the efficacy and safety of carboprost tromethamine combined with LJI for the prevention of postpartum hemorrhage would be included. Pâ<â.05 was set as the level of significance. RESULTS: The review would add to the existing literature by showing compelling evidence and improved guidance in clinic settings.

Postpartum hemorrhage is a leading cause of maternal morbidity and mortality, and uterine atony is the leading cause of postpartum hemorrhage. Risk factors for uterine atony include induced or augmented labor, preeclampsia, chorio-amnionitis, obesity, multiple gestation, polyhydramnios, and prolonged second stage of labor. Although a risk assessment is recommended for all parturients, many women with uterine atony do not have risk factors, making uterine atony difficult to predict. Oxytocin is the first-line drug for prevention and treatment of uterine atony. It is a routine component of the active management of the third stage of labor. An oxytocin bolus dose as low as 1â¯IU is sufficient to produce satisfactory uterine tone in almost all women undergoing elective cesarean delivery. However, a higher bolus dose (3â¯IU) or infusion rate is recommended for women undergoing intrapartum cesarean delivery. Carbetocin, available in many countries, is a synthetic oxytocin analog with a longer duration than oxytocin that allows bolus administration without an infusion. Second line uterotonic agents include ergot alkaloids (ergometrine and methylergonovine) and the prostaglandins, carboprost and misoprostol. These drugs work by a different mechanism to oxytocin and should be administered early for uterine atony refractory to oxytocin. Rigorous studies are lacking, but methylergonovine and carboprost are likely superior to misoprostol. Currently, the choice of second-line agent should be based on their adverse effect profile and patient comorbidities. Surgical and radiologic management of uterine atony includes uterine tamponade using balloon catheters and compression sutures, and percutaneous transcatheter arterial embolization.

BACKGROUND: Postpartum hemorrhage (PPH) remains a common cause of maternal mortality worldwide. Medical intervention plays an important role in the prevention and treatment of PPH. Prostaglandins (PGs) are currently recommended as second-line uterotonics, which are applied in cases of persistent bleeding despite oxytocin treatment. SUMMARY: PG agents that are constantly used in clinical practice include carboprost, sulprostone, and misoprostol, representing the analogs of PGF2α, PGE2, and PGE1, respectively. Injectable PGs, when used to treat PPH, are effective in reducing blood loss but probably induce cardiovascular or respiratory side effects. Misoprostol is characterized by oral administration, low cost, stability in storage, broad availability, and minimal side effects. It remains a treatment option for uterine atony in low-resource settings, but its effectiveness as a uterotonic for independent application may be limited. Key Messages: The present review article discusses the physiological roles of various natural PGs, evaluates the existing evidence of PG analogs in the prevention and treatment of PPH, and finally provides a reference to assist obstetricians in selecting appropriate uterotonics.

OBJECTIVE: We evaluated the efficacy of electroacupuncture combined with tropisetron in treating carboprost tromethamine-induced nausea and vomiting during cesarean section under lumbar anesthesia. METHODS: A total of 264 patients aged 22-40 years were enrolled, who received carboprost tromethamine and suffered nausea and vomiting during cesarean section under lumbar anesthesia. The patients were divided randomly into the control group, electroacupuncture group, tropisetron group, and electroacupuncture + tropisetron group. RESULTS: Compared to the control group, the nausea and vomiting scores decreased at T3 in both the electroacupuncture and electroacupuncture + tropisetron groups, and decreased at T4 in the electroacupuncture group, tropisetron group, and electroacupuncture + tropisetron group; the motilin, gastrin, and 5-hydroxytryptamine (5-HT) levels decreased at T5 in the other 3 groups. Compared to the electroacupuncture + tropisetron group, the nausea and vomiting scores increased at T3 in the control and tropisetron groups, and increased at T4 in the other 3 groups; the motilin, gastrin, and 5-HT levels increased at T5. CONCLUSIONS: Our study suggested that electroacupuncture combined with tropisetron could effectively relieve carboprost tromethamine-induced nausea and vomiting during cesarean section under lumbar anesthesia. The effect was better than its single application, and the reduced 5-HT, motilin, and gastrin levels might be involved in the underlying mechanism.

OBJECTIVE: To assess whether mild thrombocytopenia (platelet count 100-149 k/microliter) is associated with an increased risk of postpartum hemorrhage. METHODS: Nulliparous women with term, singleton, vertex pregnancies undergoing labor at our institution between August 2016 and September 2017 were included. The primary exposure was mild thrombocytopenia, defined as platelet count 100-149 k/microliter, and the comparator was normal platelet count (150 k/microliter or greater). Those with severe thrombocytopenia (platelet count less than 100 k/microliter) were excluded from analysis. The primary outcome was postpartum hemorrhage, determined by International Classification of Diseases, Tenth Revision codes and the hospital discharge problem list. Secondary outcomes included use of uterotonic agents (methylergonovine maleate or carboprost tromethamine), total blood loss 1,000 mL or greater, and blood transfusion. Data were analyzed by t test, χ or Fisher exact test, and multivariable logistic regression, with significance at α <0.05. RESULTS: We evaluated 2,845 eligible women, of whom 2,579 (90.2%) had normal platelet count 150 k/microliter or greater, 266 (9.3%) had platelet count 100-149 k/microliter (mild thrombocytopenia), and 13 (0.5%) had platelet count less than 100 k/microliter (severe thrombocytopenia). Compared with women with normal platelet count, those with mild thrombocytopenia had a higher rate of postpartum hemorrhage (16.9% vs 8.5%, P<.001) and were more likely to have total blood loss 1,000 mL or greater (4.5% vs 1.7%, P=.002) and receive methylergonovine maleate (10.5% vs 5.9%, P=.003) or carboprost tromethamine (6.0% vs 1.6%, P<.001) or both (3.8% vs 1.0%, P<.001), but rates of blood transfusion were no different (1.9% vs 1.5%, P=.59). The association between mild thrombocytopenia and postpartum hemorrhage persisted after multivariable adjustment for potential confounders (adjusted odds ratio 2.2, 95% CI 1.5-3.2, P<.001). CONCLUSION: Among nulliparous women with term, singleton, vertex pregnancies undergoing labor, those with mild thrombocytopenia (platelet count 100-149 k/microliter) had a twofold greater likelihood of postpartum hemorrhage compared with those with normal platelet count.

Amniotic fluid embolism is a rare but often catastrophic emergency. The non-specific clinical features and lack of diagnostic tests make it a diagnosis of exclusion. Point-of-care visco-elastometric testing is being increasingly used during obstetric haemorrhage. We present a case of amniotic fluid embolism, diagnosed and managed using rotational thromboelastography. During a precipitous labour, a 21-year-old multiparous woman became pale, distressed and disorientated. The fetus was delivered using forceps. Simultaneously maternal cardiac arrest occurred and advanced life support was commenced. As there was no obvious bleeding, pulmonary embolism was considered the most likely diagnosis and preparation was made to thrombolyse. During resuscitation, rotational thromboelastometry demonstrated haemostatic failure, supporting a diagnosis of amniotic fluid embolism. This reversed the decision to thrombolyse and focused the team on resuscitation and management of coagulopathy. Targeted blood products were given using a local protocol specific to obstetric bleeding. Return of cardiac output was achieved. The total measured blood loss was more than 3.6â¯L and transfusion was guided by point-of-care tests. Transfused blood products were six units of packed red blood cells, one pool of platelets, 12 units of fresh frozen plasma and 14â¯g of fibrinogen concentrate. This case demonstrates amniotic fluid embolism with haemostatic failure, without initial revealed blood loss. The high mortality of amniotic fluid embolism necessitates rapid diagnosis and aggressive management. Laboratory tests in this context are impractical in informing clinical decisions, showing the value of point-of-care testing in facilitating team work and timely administration of targeted blood products.

Motherwort (YiMuCao), a traditional Chinese herb, has been shown beneficial effects for women's diseases. This meta-analysis aimed to evaluate the efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss. A systematic literature search was conducted in PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang from their inception to December 2017. Randomized controlled trials that determined the add-on effects of motherwort injection to carboprost for prevention of post-partum blood loss were eligible. Pooled risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI) were used to summarize the effect sizes. Eight trials including 1276 pregnant women fulfilled the inclusion criteria. Prophylactic use of motherwort injection add-on therapy significantly reduced the post-partum 2 h (MD -127.5 mL; 95% CI -149.13 to -105.88) and 24 h (MD -146.85 mL; 95% CI -179.77 to -113.94) blood loss and incidence of post-partum hemorrhage (RR 0.28; 95% CI 0.17-0.45) than carboprost. Moreover, adjunctive treatment with motherwort injection significantly decreased the length of the third stage of labor (MD -3.41 min; 95% CI -4.33 to -2.49) and duration of lochia (MD -7.13 days; 95% CI -8.49 to -5.76). There was no statistical significant difference in the incidence of adverse events (RR 0.76; 95% CI 0.50-1.16). Prophylactic use of motherwort injection add-on therapy to carboprost tromethamine could reduce post-partum blood loss. However, more well-designed trials are necessary to confirm the findings of this study due to the methodological flaws of the included trials.

Carboprost tromethamine is a synthetic prostaglandin derivative, which can effectively promote law contraction of the uterus and significantly reduce the amount of bleeding during and after delivery. In this study, we explored the effect of carboprost tromethamine on the prevention of postpartum hemorrhage after cesarean section and the effect on coagulation function and hemodynamics. At the same time, the effects of oxytocin and carboprost tromethamine were studied in different groups. The results showed that the amount of 2h bleeding (256.7±65.21) mL and the amount of 24h hemorrhage (308.3±78.3) after the operation were significantly decreased, and the difference was statistically significant (P<0.05). After the operation, the levels of APTT, TT and Fib in the two groups were significantly lower than those before the operation. The levels of SBP (119.4±8.24) mmHg and DBP (79.6±6.21) mmHg in the experimental group were significantly higher than those of the control group. In summary, carboprost tromethamine has a significant effect on the prevention of postpartum hemorrhage in cesarean section, and has a significant effect on improving the state of hypercoagulable blood and maintaining the stable hemodynamic state, which has clinical a value.
