Patients, contamination

The last point is important in dealing with patients contamination of the eyes with bleach is a potentially serious problem. This is considered below. The N -chloro-compounds (chloroamines and Fi-clor ) are more stable, more effective and are less irritating than the hypochlorites. Chloramine has been used as a wound disinfectant and as a surgical antiseptic. Martindale (Reynolds, 1996) notes that the maximum allowable concentration in cosmetics, in the UK, is... 

Besides these functions, safety aspects are vital in developing these types of MRl compatible devices. One should avoid electric cables, metallic parts and prevention of bacteriologic and viral cross-patient contamination. One of the main advantages of optical fibre sensors is their immunity to electromagnetic radiations. 

Can get patient-to-patient contamination with the toxin on skin or clothes. 

Patients should be advised that nasal products are for one patient only and should not be passed around since the risk of inter patient contamination by nasally administered products is very high. 

Dr. Braverman told us that iodine-induced thyrotoxicosis could be diagnosed by measuring urinary iodine excretion levels. I would like to comment on this point. If the iodine contamination is of recent onset, urinary iodine will of course be elevated. However, several studies have indicated that after coronary arteriography for instance, iodine in urine will be elevated up to two weeks later. After that period it will rapidly come down to normal excretion levels. My other comment concerns the lowering of thjn-oidal radioactive iodine uptake in patients contaminated with iodine. In some patients with iodine-induced thyrotoxicosis, the radioactive iodine uptake remains elevated. Therefore, a high uptake does not exclude the diagnosis of iodine-induced thyrotoxicosis. 

Contamination of blood products with lymphocytes can lead to transfusion-induced reactions ranging from a mild fever to severe reactions such as alloimmunization and graft versus host disease (GvHD), in which the transfused lymphocytes (graft) survive the defensive immune reaction of the patient (host) and start a reaction which destroys the cells of the host. The patient also may develop an immune response to the human leukocyte antigen (HLA) type of the graft s cells and reject all platelet transfusions that do not match their own HLA system. The HLA system, found on blood platelets and lymphocytes, is more compHcated than, but similar to, the ABO blood group system of red cells. 

The fact that ceU culture-derived products are often injected into humans as therapeutic agents makes it imperative that there be no component in the final product that can pose a potential health risk to the patient. Health risks can be introduced into a product from many sources including the ceUs themselves raw materials, such as semm, media components, etc materials used in purification, eg, antibodies and external contamination. Eor a therapeutic product such risk factors are identified at the outset and ways of reducing them to acceptable levels are designed into the process. Before a product is released by the EDA the manufacturer has to demonstrate this risk reduction by rigorous validation of the process. 

Povidone—iodine is a brown, water-soluble powder containing approximately 10% iodine. However, the amount of free iodine, which is responsible for the antimicrobial activity, is low in a concentrated solution, but is released as the solution is diluted (41). Concentrated solutions have actually been contaminated with bacteria (42). For use as an antiseptic, povidine—iodine is diluted with water or alcohol to a concentration of 1% iodine. Detergents are added if it is used as a surgical scmb. lodophors are important as broad-spectmm antiseptics for the skin, although they do not have the persistent action of some other antiseptics. They are also used as disinfectants for clinical thermometers that have been used by tuberculous patients, for surface disinfection of tables, etc, and for clean equipment in hospitals, food plants, and dairies, much as chlorine disinfectants are used. 

Expert in the operations of equipment, not necessarily employees of the employer, and may perform temporary emergency response Examples crane or earth-moving equipment operations, or medical personnel whose typically duties do not include treating contaminated patients. 

Specific ventilation recommendations were included in the CDC guidelines. The recommendations for isolation rooms serve two purposes. The first is dilution of contaminant, in this case droplet nuclei in the isolation room, The second is isolation of the space occupied by known or suspected TB patients from adjacent areas. The CDC and Conroy, et al. present recommended operating conditions for isolation rooms. These three conditions are presented in the Different Forms and Boundaries Relative to Other Types section below. 

The cephalosporins also may be used perioperatively, that is, during the preoperative, intraoperative, and postoperative periods, to prevent infection in patients having surgery on a contaminated or potentially contaminated area, such as the gastrointestinal tract or vagina In some instances, a specific drug may be recommended for postoperative prophylactic use only.
