Make sure you're rotating spots so to not make one area more sore than other spots. 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. It is not necessary to follow the activated partial thromboplastin time.10 Anti-Xa levels need only be obtained in patients who are at extremes of weight (< 121 lb [55 kg] or > 198 lb [90 kg]) or have abnormal renal function.12 Monitoring of platelets while on LMWH is no longer recommended.12 UFH may be used instead of LMWH for the treatment of VTE in pregnancy, because of cost or availability.

Some authorities recommend lower extremity venous compression ultrasonography as the next test because if DVT is present, anticoagulant treatment will be the same as for PE, and venous compression ultrasonography avoids fetal radiation exposure.12,28, When d-dimer testing and venous compression ultrasonography are inconclusive, multidetector-row (spiral) computed tomography has become the test of choice for diagnosing PE in pregnancy.12,24,26 Single-slice computed tomography is inadequate in diagnosing peripheral PE, but newer-generation spiral computed tomography, tested in nonpregnant patients, has shown positive and negative predictive values comparable with pulmonary angiography.27 Fetal exposure to radiation is lower with spiral computed tomography than with ventilation-perfusion (V/Q) scanning (less than 130 Gy and 370 Gy, respectively), and fetal exposure to spiral computed tomography nonionic contrast appears safe.29 Spiral computed tomography does expose the maternal breast to greater radiation, and V/Q scanning may be preferred in women with a family history of breast cancer.12 A cost-benefit analysis supports spiral computed tomography as the preferred test for diagnosing PE during pregnancy.30. Before you handle the syringe or vial of heparin, you should wash your hands thoroughly. Multidetector-row (spiral) CT is the imaging modality of choice to evaluate for PE in pregnancy because, in nonpregnant patients, the diagnostic accuracy is equivalent to pulmonary angiography, and radiation exposure to the fetus is less than with a V/Q scan.

It is safe to inject LMWH into the abdomen while pregnant. Several methods of administering heparin (UFH or LMWH) subcutaneously have been introduced to prevent adverse pregnant outcomes. Art. Pregnant? Heparin is broken down by stomach acids and so cannot be taken by mouth.
