I got to the point that I was in so much pain that I had to have my husband start injectioning me. Clinical symptoms of deep venous thrombosis may be subtle and difficult to distinguish from gestational edema. Heparin is an anticoagulant commonly used after surgery.

Hold the syringe like a pencil in one hand, keeping your fingers off the plunger. Signs and symptoms of a DVT include Swelling of the affected limb Pain or tenderness not caused by injury During pregnancy and the immediate period after birth, the risk of venous thrombosis is increased. Your During pregnancy, a womans blood clots more easily to lessen blood loss during labor and delivery. There is no evidence from randomised controlled trials to evaluate the effectiveness and safety of different methods of administering subcutaneous heparin (UFH or LMWH) to pregnant women. 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. Whether women are treated with heparin, or LMWH, they will ultimately need to receive once or twice-daily injections until at least 6 weeks after delivery of the baby. jZNc?ypTc3*OZ3L?!.Y'Q@%t40O&MG@#&Ag"~% %~X;NE7QF ^'|_qB.Bs`n|-{ j#$>]82U%SXUX%I "UKx/]LD4m|m7+)@@ 9JSL;;{aw I've read on here that it's necesary to change injection sites, but my dr. didn't say anything about that. Copyright 2008 by the American Academy of Family Physicians. Venous thromboembolism (VTE), which encompasses deep venous thrombosis (DVT) and pulmonary embolism (PE), complicates 0.5 to 3.0 per 1,000 pregnancies,1 and is the leading cause of maternal mortality in the United States.2 A 2007 American College of Physicians and American Academy of Family Physicians practice guideline,1 based on a systematic review,3 found only 11 high quality studies relating to the management of VTE in pregnancy, and concluded that there is inadequate evidence for definitive recommendations.1, Virchow's triad of hypercoagulation, vascular damage, and venous stasis all occur in pregnancy, resulting in a relative risk of 4.3 (95% confidence interval [CI], 3.5 to 5.2) for VTE in pregnant or postpartum women compared with nonpregnant women.4, VTE risk factors include age greater than 35 years, obesity (body mass index higher than 30 kg per2), grand multiparity, and a personal or family history of VTE or thrombophilia.5,6 Bed rest, immobility for four days or longer, hyperemesis, dehydration, medical problems (e.g., severe infection, congestive heart failure, nephrotic syndrome), preeclampsia, severe varicose veins, surgery, and trauma are also associated with an increased risk.6,7 Cesarean delivery significantly increases VTE risk compared with vaginal delivery (odds ratio [OR] = 13.3; 95% CI, 3.4 to 51.4).8, Approximately 50 percent of pregnant women with VTE have a thrombophilia, compared with 10 percent of the general population.5 Current evidence does not support universal thrombophilia screening.9 However, expert opinion suggests testing women with a personal or strong family history of thrombosis or thrombophilia.10 During pregnancy, results must be interpreted with caution, because protein S levels normally fall in the second trimester.11 Massive thrombus and nephrotic syndrome can decrease antithrombin levels, and liver disease decreases protein C and S levels.12, Thrombophilic disorders may be inherited or acquired.13,14 Factor V Leiden and prothrombin G20210A mutations are the most common.13 Antiphospholipid antibody syndrome, the most important acquired thrombophilia in pregnancy, is defined by the presence of antiphospholipid antibodies and one or more clinical manifestations, most commonly thrombosis or recurrent miscarriage.15 A positive test for lupus anticoagulant, or medium-to-high titers of anticardiolipin immunoglobulin G or M antibodies, provides adequate laboratory confirmation of antiphospholipid antibody syndrome if found twice at least six weeks apart.15, Thrombophilias are associated with pregnancy complications, including early and late pregnancy loss, intra-uterine growth restriction, and placental abruption.9, DVT occurs with equal frequency in each trimester and postpartum.16 During pregnancy, 78 to 90 percent of DVTs occur in the left leg5,7 and 72 percent in the ilio-femoral vein, where they are more likely to embolize.5 In nonpregnant patients, 55 percent are in the left leg and 9 percent in the iliofemoral vein.5. After deep subcutaneous (intrafat) injections, tests for adequacy of dosage are best performed on samples drawn 4 to 6 hours after the injection. In a second study, 138 these investigators compared the efficacy and safety of heparin and aspirin. While multiple contributing factors may be involved, sadly about 50% to 75% of the time, there is no known cause for recurrent miscarriages.

However, the use of other blood thinners such as Warfarin and Unfractionated Heparin (the type that was previously used) may pose a threat to the health of the mother as well as the baby.

Although receiving subcutaneous heparin (either unfractionated heparin (UFH) or low molecular weight heparin (LMWH)) is the main option in the prevention of VTE during pregnancy, the management of thromboprophylaxis in pregnant women has mostly relied on the evidence from non-pregnant participants.
