Bleeding disorder

Penicillins should be used cautiously in patients witii renal disease, pregnancy (Pregnancy Category C), lactation (may cause diarrhea or candidiasis in die infant), and in tiiose witii a history of allergies. Any indication of sensitivity is reason for caution. The drug is also used witii caution in patients witii asthma, renal disease, bleeding disorders, and gastrointestinal disease. 

The nurse should use cephalosporins cautiously in patients with renal or hepatic impairment and in patients with bleeding disorders. Safety of cephalosporin administration has not been established in pregnancy or lactation these drugs are assigned to Pregnancy Category B. 

NSAIDs can induce a number of other adverse reactions, including bleeding disorders, anemia, thrombocytopenia, erythema nodosum, erythema multiforme, fixed drug eruptions, toxic epidermal necrolysis, Stevens-Johnson syndrome, leukocytocla-sitc vasculitis, recurrent fever with exanthema and, of course, the well-known gastric cytotoxicity. 

Onset of action is slow at around 30 minutes, which limits spontaneity. In addition, patients and partners may complain of a cold, lifeless, discolored penis that has a hinge-like feel. Painful ejaculation or inability to ejaculate are additional adverse effects. VEDs are contraindicated in persons with sickle cell disease and should be used with caution in patients on oral anticoagulants or who have bleeding disorders due to the increased possibility of priapism. 

Von Willebrand disease (vWD) is the most common inherited bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor. The disease prevalence is estimated at 30 to 100 cases per million. In contrast to hemophilia, vWD is inherited as an autosomal dominant disorder (although autosomal recessive cases exist), ensuing equal frequency in male and females.16... 

This review will attempt to explore our current understanding of both coagulation and fibrinolytic systems, their clinical impact, and variables affecting the laboratory assessment of thrombotic and bleeding disorders. 

Factor IX obtained from blood donations is normally only partially pure. In addition to factor IX, the product contains lower levels of factors II, VII and X and has also been used to treat bleeding disorders caused by a lack of these factors. 

Complications of fish oil supplementation such as thrombocytopenia and bleeding disorders have been noted, especially with high doses (EPA, 15 to 30 g/day). 

Fresh frozen plasma replaces clotting factors. Although it is often overused, the product is indicated if there is ongoing hemorrhage in patients with a PT or aPTT greater than 1.5 times normal, severe hepatic disease, or other bleeding disorders. 

The prevention of excessive blood loss through breaches of the vascular barrier is important to maintain oxygen delivery and blood volume. A fall in blood volume would cause a drop in blood pressure and the metabolism of all of the major organs would be badly affected. Failures of the haemostatic mechanisms can lead to haemorrhage (bleeding disorders) or thrombosis (hypercoagulation disorders). 

Parahemophilia is an autosomal recessive bleeding disorder characterized by a reduced plasma concentration of the Factor V blood copulation protein. Deficiency arises from a 12 base-pair deletion in the Factor V gene that impairs the secretion of Factor V by hep-atocytes and results in an abnormal accumulation of immunoreactive Factor V antigen in the cytoplasm. In which region of the Factor V gene would this mutation most likely be located ... 

Hemophilia B, another X-linked recessive bleeding disorder, is caused by a deficiency of dotting factor IX.

Administration - A6m n ster by subcutaneous injection only do not administer IM. Screen patients prior to prophylactic administration to rule out a bleeding disorder. There is usually no need for daily monitoring of enoxaparin s effect in patients with normal presurgical coagulation parameters. 

TINZAPARIN Evaluate all patients for bleeding disorders before administration of tinzaparin.
