Reatment strategies, besides addressing reversible causes, aim to stabilize the cardiac membrane and remove excessive extracellular potassium. Calcium calcium stabilizes the cardiac membrane, and its e ect starts within minutes but lasts only 30–60 minutes. Both calcium chloride and calcium gluconate in usion can be used, but calcium chloride contains 3 times the amount o calcium compared to calcium gluconate and is pre erred in unstable conditions. Insulin and glucose insulin drives potassium into cells through the na-k pump present on muscular tissues and needs to be ollowed by administration o glucose to prevent hypoglycemia (10–20 units insulin iv, combined with 50 ml o dextrose 50% i the serum glucose is less than 250 mg/dl). He e ect starts 20 minutes a ter the in usion and lasts or 4–6 hours. Glucose level should be monitored about one hour a ter the in usion. Β 2 agonists albuterol can provide transient intracellular shi t o potassium through the same mechanism o insulin and can be given as adjunct to insulin to potentiate its e ects. E ective dose is about 4 times the one used or bronchodilation and maximum e ect is seen within 90 minutes. At this dose, tachycardia can be a notable side e ect and presence o cardiac disease needs to be considered prior to use. Sodium polystyrene sul onate (kayexalate) cation exchange resins exchange sodium or excreted potassium in the colon cells and are given orally or rectally combined with a laxative to avoid constipation. He onset o action is variable (2–6 hours). Its slow e ects and severe side e ects reported (colon ischemia) make this therapy a distant choice or nonurgent treatment o chronic hyperkalemia, in cases when dialysis is not easible. Loop diuretics + intravenous uids in usions intravenous luids (ns or sodium bicarbonate) can be used to improve potassium excretion at the nephron level.

Frequent monitoring and periodic dosage adjustments, making therapy cumbersome. Warfarin should only be used when a systematic patient monitoring system is available. The oral factor xa inhibitors rivaroxaban and apixaban are newer options for vte prevention following hip and knee replacement surgery and offer a convenient alternative to traditional anticoagulants. 5,34–36 both agents have shown superior efficacy compared to lmwh with a similar rate of bleeding complications. Rivaroxaban is given at a fixed dose of 10 mg once daily, and apixaban is given at a fixed dose of 2. 5 mg twice daily. Both are given without the need for routine laboratory monitoring and dosing adjustments (as with warfarin) and without the inconvenience of administration by injection (as with lmwh and fondaparinux). The optimal duration for vte prophylaxis is not well established but should be given throughout the period of risk. For patients who have undergone total knee replacement, total hip replacement, or hip fracture repair, prophylaxis is recommended for a minimum of 10 to 14 days. However, extending it up to 35 days is recommended due to continued vte risk up to one month postsurgery. 5–7,34 treatment desired therapeutic outcomes the goal of vte treatment is to prevent short- and long-term complications of the disease. The aim of initial therapy is to prevent propagation or local extension of the clot, embolization, hemodynamic collapse, and death. The goal of long-term and extended therapy is to prevent complications such as pts, pulmonary hypertension, and recurrent vte. 2,12 general treatment principles anticoagulant drugs are considered the mainstay of therapy for patients with vte, and the therapeutic strategies for dvt and pe are similar. 2,12 management decisions are guided by balancing the risks and benefits of various treatment options. The treatment of vte can be divided into three phases. Acute (first 5–10 days), long term (first 3 months), and extended (beyond 3 months). 12 the acute treatment phase of vte is typically accomplished by administering a fast-acting parenteral or a doac (table 10–8). The long-term and extended phase treatments of vte are usually accomplished using oral anticoagulant agents such as warfarin, or one of the doacs (apixaban, dabigatran, and rivaroxaban). 2,12 in certain populations, such as patients with cancer and women who are pregnant, the lmwhs are the preferred agents during long-term and extended treatment phases due to better safety or efficacy. 2 the etiology of vte will guide the duration of therapy.
