Although numerous nonrandomized studies have and Society of Critical Care Medicine, have published consensus reported a nonsignifcant trend toward improved survival using statements for glycemic control of hospitalized patients (338– continuous methods (357–364), two meta-analyses (365, 366) 341). These statements usually targeted glucose levels between reported the absence of signifcant difference in hospital mor- 140 and 180 mg/dL. As there is no evidence that targets between 140 and 180mg/dL are different from targets of 110 to 140mg/ tality between patients who receive continuous and intermittent dL, the recommendations use an upper target blood glucose renal replacement therapies. This absence of apparent beneft of ≤ 180mg/dL without a lower target other than hypoglycemia. The continuation of have been published (367–371); four found no signifcant dif- insulin infusions, especially with the cessation of nutrition, has ference in mortality (368–371), whereas one found signifcantly been identifed as a risk factor for hypoglycemia (332). Balanced higher mortality in the continuous treatment group (367), but nutrition may be associated with a reduced risk of hypoglyce- imbalanced randomization had led to a higher baseline severity mia (342). When a multivariable model was used glucose levels over time is an important determinant of mortal- to adjust for severity of illness, no difference in mortality was ity (343–345). Hyperglycemia and glucose variability seem to be apparent between the groups (367). Most studies comparing unassociated with increased mortality rates in diabetic patients modes of renal replacement in the critically ill have included compared to nondiabetic patients (346, 347).

The need to extrapolate from general, acutely ill patients evidence supports the use of bicarbonate therapy in the treat- to critically ill patients to septic patients downgrades the ment of hypoperfusion-induced lactic acidemia associated with evidence. Because the patient’s risk of administration is reveal any difference in hemodynamic variables or vasopressor small, the gravity of not administering may be great, and the requirements (378, 379).

Standard precautions are work practices that were designed based on the assumption that all blood and all body fuids are potentially infectious buy proventil 100mcg with mastercard. These precautions are recommended to prevent disease transmission in schools and should be adopted for contact with all blood and body fuids order 100mcg proventil overnight delivery. Hand washing Hand washing is the single most effective way to prevent the spread of infection cheap 100 mcg proventil amex; its purpose is to remove or destroy germs that are picked up on the hands 100mcg proventil overnight delivery. Germs can be picked up in lots of ways including when we touch other people, animals, contaminated surfaces, food and body fuids. These germs can then enter our body and make us ill or they can be passed to other people or to the things that we touch. Germs picked up on the hands can be effectively removed by thorough hand washing with soap and running water. Pupils of all ages should be encouraged to wash their hands and school staff should avail of every opportunity to emphasise the importance of clean hands to pupils in the prevention of the spread of infection. Hand washing facilities Good toilet and hand washing facilities are important for infection control. Cleaning staff should be reminded to check the soap dispensers at frequent intervals. When to wash hands Before • Handling or preparing food • Lunch and meal breaks • Providing frst aid or medication After • Providing frst aid or medication • Touching blood or body fuids • Using the toilet • Coughing, sneezing or wiping ones nose • Touching animals • Removing protective gloves See Appendix 2, 3, 4 and 5 for posters on hand washing Hand washing products • Liquid soap and warm running water should be provided. Bar soap is not recommended as the soap can easily become contaminated with bacteria. Water temperature • Ideally, wash hand basins should have hot and cold mixer taps that are thermostatically controlled to deliver hot water at a maximum temperature of 43◦C to avoid scalding. If the plumbing system only supplies cold water, a soap that emulsifes easily in cold water should be provided. Include the thumbs, fnger tips, palms and in between the fngers, rubbing backwards and forwards at every stroke (see Posters on hand washing technique in the Appendices). Drying • Good quality disposable paper towels (preferably wall mounted) should be available at or near the wash hand basins for drying hands. Alcohol based hand rubs/gels Alcohol based hand rubs/gels are not a substitute for hand washing with soap and running water and are not generally recommended for routine use in educational settings because of concerns over safety, and the fact that the rubs/gels are not effective when used on hands that are visibly dirty (a common feature among school children). Alcohol-based hand rubs and gels are a good alternative when soap and running water are not available, (e. Method • Apply the required volume of the product to the palm of one hand and rub the hands together. The amount of gel used should be enough to keep the hands wet for at least 15 seconds. Health and Safety As with any other household product or chemical, alcohol hand rubs can be hazardous if used inappropriately. If alcohol hand rubs/gels are used in the school setting, care should be taken to ensure that children do not accidentally ingest hand washing products. Hand washing and young children Good hand washing habits should be taught to young pupils as early as possible. This can be done by: • Showing children a good hand washing technique (See posters on hand washing in Appendices). Gloves Disposable gloves should be worn when dealing with blood, body fuids, broken or grazed skin, and contact with mucous membranes (e. Medical/examination gloves • Disposable, powder free gloves made of either natural rubber latex or nitrile are suitable for use in these circumstances as they have good barrier properties. Medical/examination gloves are recommended for: • Dealing with nosebleeds or cuts. Household gloves are suitable for: • Cleaning and disinfecting bathrooms or any areas contaminated with faeces, vomit or urine. General points • Single use gloves should be discarded after each use or if punctured, torn or heavily contaminated. Personal hygiene Items that may be contaminated with blood or body fuids should not be shared including: • Towels, fannels and toothbrushes.
