Filter by:This is a two year, multicentre, mixed methods feasibility study including a randomised controlled two-arm interventional trial, a nested qualitative study, focus groups and a United Kingdom (UK) wide survey exercise.
The purpose of this study is to see if a compression device on the arm where a peripherally inserted central catheter (PICC) line has been inserted can prevent the formation of a blood clot around the PICC line.
We propose an observational study to assess the ability of intensivists to evaluate for deep vein thrombosis using 2 point compression ultrasonography.
This trial is a prospective, single-center Phase II randomized study to demonstrate the superior efficacy of Fondaparinux Sodium subcutaneous injections in patients undergoing CABG surgery (isolated and redo isolated) versus treatment with placebo. All consecutive patients scheduled for CABG surgery that meet the general inclusion and none of the exclusion criteria will be considered for enrollment in the study. Consecutive patients will be randomized on the day of admission prior to their CABG surgery into one of two groups. One group will be randomized to the placebo while the second group will receive 2.5 mg Fondaparinux Sodium injections. Both groups will receive routine mechanical prophylaxis as determined by the treating physicians. Group randomized to receive Fondaparinux Sodium will receive a 2.5 mg SQ daily drug dose starting 12 +/- 2 hours post-wound closure or the following day in the morning (at the discretion of the cardiothoracic surgeon). The second dose would be administered 24 hours later and the dosing will then be once a day. The group randomized to placebo will receive subcutaneous equivolume isotonic saline at the same time points described above. Patients randomized will receive a 2.5 mg dose of Fondaparinux Sodium or placebo subcutaneously for a total of 3-9 days post CABG with day 1 being the day of surgery. The drug will be discontinued if the patient is discharged before day 9. If the patient stays for more than 9 days inside hospital, a duplex would be obtained per protocol and further DVT prevention measures would be instituted per the discretion of treating physician. Patients will be assessed daily while hospitalized for any symptoms and adverse reactions and will undergo laboratory testing (CBC, PT/INR, PTT and UA) as specified in the protocol. Post-op day 3-9(no later than 2 days after the last preventive drug dose) patients will undergo the protocol specific lower limb venous duplex scan and earlier if symptomatic. Patients will also be contacted (phone/office visit) for follow-up 25-35 days post CABG to assess for signs or symptoms of deep venous thrombosis or thromboembolism and for any potential complications.
The primary objective was to study the clinical benefit with dalteparin sodium in thromboprophylaxis in primary care medical subjects. The secondary objective was a pharmacoeconomic evaluation of hromboprophylaxis with dalteparin sodium in primary care medical subjects.
The primary hypothesis of this study is that occult catheter-related DVT in children with cancer is common and directly contributes to development of serious catheter complications, specifically bacteremia/fungemia and/or recurrent occlusion of the catheter tip. Accordingly, anticoagulant treatment of clinically silent (occult) DVT will reduce rates of catheter-related infection and occlusion, delays in therapy and need for catheter replacement.
A single centre, single-arm study to evaluate safety and efficacy of microplasmin administration via the Trellis-8 Infusion System in patients with acute iliofemoral DVT
The purpose of this study is to assess the effect of the anticoagulant(blood thinner) Clexane on the development of leg clots following electrophysiology studies (EPS) and or radiofrequency ablation (RFA). People who suffer heart palpitations will sometimes need hospital admission to undergo an electrophysiology study ( and or a Radiofrequency Ablation)in order to diagnose and or treat their condition. Radiofrequency ablation is a procedure to stop abnormal heart rhythms. EPS/RFA studies require the puncture of the leg veins . Previous experience has shown that following the puncture of leg veins there is a small risk of developing a blood clot in the leg. It is not known whether giving blood thinners (anticoagulants) after the procedure will decrease this risk Enoxaparin Sodium (Clexane) is an anticoagulant used extensively and safely following bone (Orthopaedic) surgery to prevent blood clots from developing in the legs
To simplify and improve the diagnostic approach to patients with clinically suspected recurrent DVT by determining whether the results of the combination of IPG and d-dimer testing, using a whole blood agglutination assay, can be used in the management of such patients.
Study Plan: Adult cancer patients who have a low risk profile and present with DVT will receive dalteparin 200 IU/kg subcutaneously daily (based on actual body weight with a maximum dose of 18,000 IU). Eligible patients who have signed the informed consent will be instructed on injection technique, will give themselves their first subcutaneous injection under supervision of the physician or the nurse and will be observed for a minimum of 1-2 hours prior to discharge. Patients may be admitted to an observation unit for up to 24 hours prior to discharge if medically necessary. Those patients without complications during the observation period will be given discharge instructions and an outpatient schedule to see one of the physician investigators daily for their subcutaneous injection of dalteparin, routine lab work and initiation of oral anticoagulation therapy. Patients that are proficient in administering their own injection with dalteparin will be evaluated every other day by the physician investigator. On days of home injection, the study nurse will call the patient to check on the patient's status and to remind the patient of his/her daily injection. Patients will undergo a physical examination every other day by the physician investigator directed towards the clinically affected areas until a therapeutic response (INR 2-3) on oral warfarin has been achieved or the patient's clinical condition warrants modification of therapy with or without hospitalization. Patients will remain on study for a minimum of 5 days with at least 1 day of therapeutic oral anticoagulation. The quality of life of the patients enrolled will be assessed by using the Modified Medical Outcome Study Short Form-20. An adapted version of the Rotterdam Symptom Checklist will be used to specifically assess patients with thrombosis. Patients will complete these two instruments at study entry, day 3, day 5 and at the end of study if different from day 5.
