Venous thromboembolism (VTE) is a disease made up of deep vein thrombosis (DVT) and pulmonary embolism (PE). It is a common‚ lethal disorder that affects 10% to 20% in general medical patients and up to 80% in critically ill patients. This disorder recurs frequently‚ is often overlooked‚ and results in long-term complications. It is important to determine the benefits of preventing VTE through pharmacological modality such as low-molecular-weight heparin and also non-pharmacological modality such

Venous Ulcer A venous ulcer is a shallow sore on your lower leg caused by poor circulation of the veins. This condition used to be called a stasis ulcer. Veins have valves that help blood return to the heart. If these valves do not work properly‚ blood flows backward and backs up into the veins near the skin. This causes the blood to pool in your lower legs. The blood can then can leak out of your veins and irritate your skin. This may cause a break in your skin and lead to stasis venous ulcer

When veins do not work properly‚ it is called venous insufficiency. This means that the veins are not effectively sending the blood back to the heart. The severity of venous insufficiency differs with each person. If the problem goes untreated‚ the person may feel continuous symptoms of pain‚ swelling and fatigue in the legs and ankles. If the problem is advanced there are other symptoms such as leg ulcers‚ superficial thrombophlebitis‚ spontaneous bleeding and‚ possibly‚ deep vein thrombosis. Our

Immediately following the placement of the catheter‚ begin selecting the NAVA level‚ or the sensitivity of the catheter that is needed to pick up the electrical activity. Neuromuscular signal strength will greatly alter the level needed to support the patient. For example‚ stronger neuromuscular signals will need a decreased NAVA level to provide ventilation‚ while weak neuromuscular signals will require a higher NAVA level. A calculation can be done to estimate the level of PEEP needed. The calculation

Venous Ulcers Homework 1. True/false: The medium and large veins in the leg have bicuspid valves to prevent retrograde venous blood flow‚ but the perforating veins do not have valves. False 2. What causes the ulcers to form in patients with venous insufficiency? [The question is what causes ulcers to form‚ not what causes venous insufficiency (people can have venous insufficiency and varicose veins for years without ulceration)] Ulceration is caused by hypoxia‚ which is a decrease in the amount

brachial plexus catheters provide intraoperative anaesthesia as well as control post-operative pain [1]. Anaesthesiologists use ultrasound (US) with or without peripheral nerve stimulation (PNS) for the placement of these blocks. When comparing the two modes of placement‚ most authors have looked at performance time and success in single injection blocks with small sample size [2-5]. We do not know if either technique alone improves success when used to place infraclavicular catheters. We designed

Tunneled Catheter Insertion Tunneled catheter insertion is a procedure to insert a thin‚ flexible tube (catheter) into a vein. The catheter makes it easier to draw blood‚ give blood products‚ remove waste products from the blood (hemodialysis)‚ and give medicines. This procedure is usually done when the bloodstream needs to be accessed many times over a long period of time. Tunneled catheters can be placed in different parts of the body depending on how they will be used. The most common place
