Preventing Infection While Inserting Central Venous Catheters (CVCs) Newborn and premature critically ill infants in neonatal intensive care units face many challenges. Infants have delicate veins‚ so peripheral IVs usually last only a few days. A centrally inserted intravenous line is similar to a peripheral IV line‚ but lasts longer. It is difficult to insert these lines in newborn and premature infants and takes several attempts‚ thus making them more prone to infections‚ especially nosocomial

OUTCOMES 15.6‚ 15.7‚ 15.8 8. If a patient develops a blood clot in the femoral vein of the left lower limb and a portion of the clot breaks loose‚ where is the blood flow likely to carry the embolus? What symptoms are likely? To add to your thoughts‚ the blood flow is likely to carry the embolus to the patient’s lungs. This is called a pulmonary embolism. Pulmonary embolisms usually originate in the legs‚ like in this case. They are caused by a blood clot that has traveled to your lungs. There

1. The Structures of the Human Heart The human heart has four chambers: two ventricles‚ each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels‚ and two atria‚ each of which is a muscular chamber that drains and then squeezes blood into the ventricles. The two atria reside at the top of the heart; the two ventricles are at the bottom. And‚ the heart is divided into left and right halves‚ so there is a left atrium and left ventricle‚ as well as a right atrium

Deep vein thrombosis often occurs in patients having major surgery‚ particularly orthopedic surgical patients especially if they are immobilized for any length of time post-operatively. Deep vein thrombosis could eventuate in fatal pulmonary embolism; this is preventable with appropriate prophylaxis. Joanna Briggs Institute (2008) reviewed that the risk of deep vein thrombosis formation rises with the duration of the operative procedure and period of immobility. This paper will look at 5 different

Bacteria have invaded Lola’s lower lobe of her right lung and we shall report the invasion and document all we see. Let’s proceed. We are being injected into the femoral vein close to the groin area. The femoral vein runs parallel with the femoral artery through the upper thigh and pelvic region of the body. (Yahoo Health‚ 2013) Being one of the larger veins in the body‚ the
