•• it may improve the quality of life of patients receiving home pn by allowing the patient time off of pn to engage in normal activities of daily living. •• while data are limited, it may help prevent and alleviate pn-associated liver disease by avoiding continuous compulsive nutrient overload on the liver. 28 concerns with cycling pn include hyperglycemia with high infusion rates, reactive hypoglycemia when pn infusion is stopped, and fluid and electrolyte abnormalities. Random capillary blood glucose concentrations should be checked approximately 4 hours into the pn cycle (~2 hours after reaching goal rate), 15 to 60 minutes after pn stops, and intermittently during the pn cycle as needed for glycemic control. During cyclic pn infusion, the potassium infusion rate should not exceed 10 meq/ hour (10 mmol/hour) if the patient is not on a cardiac monitor. If nocturnal cyclic pn infusion interferes with patient’s sleep pattern by causing overdiuresis, the pn cycle can be extended over a longer infusion time or pn can be infused during other times of the day that are most convenient to the patient.

Many complications are related to overfeeding (table 100–8). Hyperglycemia hyperglycemia is one of the most common complications associated with pn therapy. The rate of dextrose oxidation may be reduced in patients with stress and hypermetabolism, patients with diabetes or acute pancreatitis, and patients receiving certain medications (eg, corticosteroids, vasopressors, octreotide, and tacrolimus).

Hypoxemia should be treated with supplemental 0 2 online pharmacy viagra overnight shipping and/ or ventilation. Hyperoxia may cause decreased cbf or exacerbate free radical damage. 3. Temperature. Passive cooling by turning off warming lights is an effective way to initiate therapeutic hypothermia as soon as possible after the hi insult. Hyperthermia should always be avoided. 4. Perfusion. Cardiovascular stability and adequate mean systemic arterial bp are important in order to maintain adequate cerebral perfusion pressure. 5. Maintain physiologic metabolic state a. Hypocalcemia is a common metabolic alteration after neonatal asphyxia. It is important to maintain calcium in the normal range because hypocalcemia can compromise cardiac contractility and may cause seizures (see chaps. 25 and 56).

Sputum gram stain. Moderate gram-positive cocci, few gram-negative bacilli, many wbcs. Sputum culture is pending given this additional information, what is your assessment of the patient’s condition?. Identify your treatment goals for the patient. What organisms should you include in your list of potential pathogens?. What pharmacologic agents are available for treating this patient?. 1070  section 15  |  diseases of infectious origin •• ribosome protection (tetm gene) inactivating tetracyclines •• alteration of dna gyrase or topoisomerase iv inactivating fluoroquinolones s. Pneumoniae resistance to commonly prescribed antimicrobials such as the penicillins and macrolides/azalides dramatically increased in the late 1980s through the mid- to late 1990s and has remained relatively flat in the 2000s. Resistance information collected nationally along with susceptibility testing for a new antimicrobials, demonstrates that average national rates of resistance to penicillin and macrolides were approximately 13% and 38%, respectively. 25,26 resistance to trimethoprim/sulfamethoxazole is approximately 25%, and fluoroquinolone resistance remains less than 0. 5%. 26 for hcap, hap, and vap, the risk of infection from an mdr pathogen is relatively high. The number and type of organisms that are mdr vary from hospital to hospital, making it more difficult to generate guidelines for treatment. Therefore, the treatment recommendations may be too broad or too narrow for any given institution. Treating patients with hcap, hap, or vap is more complex than treating patients with cap. There are many factors to consider, and one of those relates to the timing of infection to the most likely pathogens. Early-onset infection is less likely to be caused by mdr pathogens than late-onset infection. In early-onset infection, community pathogens such as pneumococcus, legionella, and mycoplasma need to be considered as well as some of the hospital pathogens. Patients developing lateonset pneumonia are at increased risk for resistant pathogens or mdr pathogens such as mrsa, enteric gram-negative bacilli, pseudomonas, and acinetobacter. Risk factors for developing infection caused by a resistant pathogen are as follows. •• antimicrobial therapy in preceding 90 days •• current hospitalization of at least 5 days •• high occurrence of antibiotic resistance in the community or in the specific hospital unit •• immunosuppressive disease and/or therapy •• presence of risk factors for hcap. •• hospitalization for 2 days or more in the preceding 90 days •• residence in a nursing home or extended-care facility •• home infusion therapy (including antibiotics) •• peritoneal or hemodialysis within 30 days •• home wound care •• close contact family member with mdr pathogen once these issues are addressed, antimicrobial therapy can be selected and initiated. The patient- and drug-related categories are common to all types of pneumonia, but the organisms vary with the type of pneumonia.
