In addition, the company that manufactures Lovenox warns that pregnant people who have prosthetic heart valves should be cautious when using Lovenox, as it may result in valve thrombosis. Dr. Langon also believes that as an anticoagulant (blood thinner), Lovenox is a better option than aspirin. I was at the doctor's the other day for my last appoint before my scheduled induction which will be at 39w4d. The most common (but generally rare) side effects of Lovenox include: Anyone can develop a blood clot during their lifetime, but people who are pregnant have an increased risk of blood clots. Clinical suspicion is confirmed in 10 percent of pregnant women, compared with 25 percent of nonpregnant patients.17 Typical symptoms are unilateral leg pain and swelling. Theoretically the goal is to hold the dose of heparin the night before and morning of my induction so that Im at a lower risk of bleeding and able to receive an epidural so I wish. I don't look forward to the 2x a day shots. However, the American College of Obstetricians and Gynecologists and other professional societies continue to recommend switching from LMWH to UFH, at doses of 10,000 international units of UFH, administered subcutaneously every 12 hours in the third trimester unless the aPTT is elevated, irrespective of indication (prophylactic or therapeutic use).5.

Comparison of continuation of low-molecular-weight heparin versus switching to unfractionated heparin in the peripartum. The hope is that I can go naturally and that's why they are changing it over at 35 weeks (I'm actually measuring ahead anyway). Lovenox has more predictable dosing and monitoring parameters; thus, it's preferred over heparin for home use. An alternative option for women on either prophylactic or adjusted-dose LMWH may be to stop anticoagulation and induce labor within 12 to 24 hours respectively, if clinically appropriate 4. While at this time, there isnt much evidence about the safety of Lovenox during pregnancy, Dr. Langdon indicates that for the most part, there are not adverse fetal or pregnancy effects.. Venography still serves as the definitive test for diagnosing DVT19 and may be used in clinical situations where noninvasive tests are equivocal, empiric anticoagulation is relatively contraindicated, and clinical suspicion is high.24, Figure 2 outlines a diagnostic approach for suspected PE based on expert opinion derived from studies mostly involving nonpregnant patients.2427, With low or moderate clinical suspicion, a negative highly sensitive d-dimer test rules out PE.25,28 If d-dimer testing is positive, or if clinical suspicion is high, additional testing is needed. Finally, the advantages of using UFH include the ease of rapid reversal with protamine sulfate, as well as lower cost when compared to LMWH. doi: 10.4103/1817-1737.134050.

The following are some suggested recommendations based on clinical circumstances: These suggestions should be adapted for patients with acute medical or pregnancy complications that might complicate the planning or timing of delivery. However, women who delivered at < 34 weeks of gestation were five times more likely to be switched to UFH in the peripartum period (P < 0.004), with 82% (42 women) on prophylactic LMWH dosing and 18% (nine women) on therapeutic dosing.3 The type of anticoagulation used (prophylactic vs. therapeutic) did not affect the kind of pain relief option women received (regional vs. general anesthesia). Michaels LA, Gurian M, Hegyi T, Drachtman RA. also my baby was 8lbs 10oz so made my risk slightly higher. Heparin works in a slightly different way so you can just switch over. Similarly, among women who received their last dose of anticoagulant > 24 hours prior to delivery, multivariate analysis demonstrated there was no statistically significant difference between the groups (2.0% vs. 3.0%, respectively; RR, 0.5; 95% CI, 0.13, 2.0; P = 0.33). This heightened risk exists during pregnancy, delivery, and within the first three months of having a baby.

UFH is considered an acceptable alternative.32 Table 1 recommends dosages and monitoring.10,12,32,41 For postpartum DVT or PE, warfarin may be started concomitantly with heparin.42 LMWH or UFH should be continued until an international normalized ratio of 2.0 to 3.0 is achieved for two consecutive days.42 Post-thrombotic syndrome can be prevented if compression stockings are worn for at least one year starting in the first month after a DVT.1, Intrapartum management may vary depending on the indication for anticoagulation and whether therapeutic or prophylactic doses have been used.10 Expert guidelines suggest that women receiving adjusted-dose LMWH or UFH be instructed to discontinue heparin injections at the onset of labor to prevent anticoagulant complications during delivery.12,32 When delivery is predictable, as for elective induction or planned cesarean birth, LMWH or UFH should be discontinued 24 hours before delivery.12,32 For high-risk patients, such as those with mechanical heart valves or recent VTE, the American College of Obstetricians and Gynecologists (ACOG) recommends switching to intravenous heparin at the onset of labor.10 The short half-life of intravenous UFH allows discontinuation four to six hours before the anticipated time of delivery.10,32 To minimize spinal and epidural hematoma risk, the ACOG and the American Society of Regional Anesthesia advise avoiding regional anesthesia for 24 hours after the last LMWH dose for women on twice daily therapeutic doses of enoxaparin (Lovenox), and for 12 hours after the last dose of LMWH for women receiving daily prophylactic dosing.10, Evidence is insufficient to recommend for or against an inferior vena cava filter if anticoagulation is contraindicated or repeat PE occurs despite adequate anticoagulation.1, Systematic reviews of observational studies have found VTE prophylaxis with LMWH to be safe and effective in pregnancy, but there are no randomized controlled trials confirming this.35,42 Table 2 lists representative prophylactic doses of LMWH and subcutaneous UFH.6,43 Table 3 summarizes recommendations for the type and duration of prophylaxis based on specific clinical risk factors.5,10,15,32,39,40 Consultation should be considered for high-risk thrombophilias such as antithrombin deficiency.6, Low-dose aspirin (75 to 81 mg) is sometimes used for women with an increased risk of thrombosis that does not meet the threshold for prophylactic heparin (e.g., a woman with a mild thrombophilia and no history of VTE).6 Due to the lack of studies of aspirin for this indication, such treatment is of unknown benefit; however, low-dose aspirin is safe to use during pregnancy.32, Postpartum thromboprophylaxis is not routinely indicated following vaginal delivery,42 but may become necessary because of labor-related risk factors, such as prolonged labor, mid-forceps delivery, and immobility after delivery.6, Unless other VTE risk factors are also present, women who undergo a scheduled cesarean delivery are not routinely placed on pharmacologic VTE prophylaxis.44 However, mechanical prophylaxis with pneumatic compression stockings has been shown to provide effective post-cesarean thromboprophylaxis.45 Graduated compression stockings provide effective prophylaxis in nonpregnant postoperative patients.46 A decision analysis comparing pneumatic compression stockings with no intervention for post-cesarean VTE prophylaxis found the former to be cost-effective.47.
