A thin polymer film that seals surgical wounds could make sutures a relic of medical history.
Measuring just 50 microns, the film is placed on a surgical wound and exposed to an infrared laser, which heats the film just enough to meld it and the tissue, thus perfectly sealing the wound. Known as Surgilux, the device's raw material is extracted from crab shells and has Food and Drug Administration approval in the US
Beating heart or "off pump" coronary artery surgery is the latest revolution in the management coronary disease. It is being embraced world-wide by increasing numbers of surgeons. Many of the advantages are subtle but reduced mortality, stroke, and bleeding as well as earlier discharge are well-established benefits. A cardiac stabiliser is mandatory for this surgery, most are single use only and very expensive, this one is multiple use and is saving many healthcare dollars
If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc. Because a bulging disc does not always show symptoms, many people have bulging discs without realizing it. As long as the bulging area does not press against a nearby nerve, no symptoms occur. When the bulging disc does cause a pinched nerve, however, you may begin to experience symptoms. In the lower back, the damaged disc can cause pain to travel to the hips, buttocks, legs and feet. In the cervical spine, pain can radiate from the neck, down the arm and to the fingers.
It then spreads down the bundle of his and then purkinje fibres to cause ventricular contraction. So when viewing the heart from the front, the direction of depolarisation is 11 o'clock to 5 o'clock. The general direction of depolarisation is known as the cardiac axis.
An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. Thin wires connect the ICD to your heart. If an abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat if your heart is beating chaotically and much too fast.
The syndrome of inappropriate antidiuretic hormone (ADH) secretion (SIADH) is defined by the hyponatremia and hypo-osmolality resulting from inappropriate, continued secretion or action of the hormone despite normal or increased plasma volume, which results in impaired water excretion.
