Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The use of a new generation low molecular weight heparin (Bemiparin)and the well known LMWH (Enoxaparin) after Caesarean sections and vaginal deliveries in a risky group patients for venous thrombosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Venous thromboembolism (VTE) is the leading cause of maternal mortality and morbidity in the developed and developing world. Pulmonary embolism and deep vein thrombosis are the two components of a single disease called deep vein thrombosis (DVT). Pregnancy associated with an average 5 to 10 fold increase in the risk of VTE compared with non-pregnant women. The highest incidence occurring during the post partum period. There are many researches done a broad on the effect of LMWH to decrease the incidence of VTE after Caesarean section using the two LMWH (Enoxaparin and Bemiparin) alone but not in one research comparing both of them alone and both together against a control group. Also according to our knowledge there are no published literature on thromboprophylaxis after vaginal delivery

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

SEQUENTIAL

A prospective clinical trial with sequential group allocation Women eligible for participation were assigned to the three arms of the trial: the bemiparin, enoxaparin, and control groups. Based on a schema produced by a Microsoft Excel (2007) computer program, the first woman was recruited to the non intervention group (control), the second to the bemiparin group, and the third to the enoxaparin group, with this sequence repeated throughout the trial
Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

A prospective non-randomized clinical trial, no masking was applied to the 3 arms of the study

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Bemiparin

A new second generation Low Molecular Weight Heparin

Group Type ACTIVE_COMPARATOR

Bemiparin

Intervention Type DRUG

Bemiparin sodium 3,500 IU anti Xa/0.3 ml solution for injection in pre-filled syringe will be provided for each patient in Bemiparin group; subcutaneously 6 hours after delivery(vaginal and Caesarean)and then daily for up to 7 days.

Enoxaparin

Intervention Type DRUG

Enoxaparin sodium 40mg (equivalent to 4,000 IU anti-Xa activity) in 0.4ml water for injection will be administered subcutaneously 6 hours after the delivery( vaginal or abdominal)then daily up to 7 days post partum, for Enoxaparin group of patients.

Enoxaparin

A well known Low Molecular Weight Heparin

Group Type ACTIVE_COMPARATOR

Enoxaparin

Intervention Type DRUG

Enoxaparin sodium 40mg (equivalent to 4,000 IU anti-Xa activity) in 0.4ml water for injection will be administered subcutaneously 6 hours after the delivery( vaginal or abdominal)then daily up to 7 days post partum, for Enoxaparin group of patients.

control group

Participants assigned to the Non-Interventional Arm will receive standard local hospital care as dictated by the attending physician and established clinical guidelines. Examples of standard care include, but are not limited to, patient rehydration protocols and support for ambulation or mobilization within the clinical setting. All standard safety and monitoring procedures will apply.
