Patient preparation

When treating acne vulgaris, topical and systemic therapies (if indicated) are initiated 2 to 4 weeks prior to peeling. Topical antibiotics and benzoyl peroxide based products can be used daily and discontinued 1 or 2 days prior to peeling. However, unless a deeper peel is desired, retinoids should be discontinued 7-10 days prior to salicylic acid peeling. Broad-spectrum sunscreens (UVA and UVB) should be worn daily (see Photo damage. Sunscreen section). 

Before starting the procedure, in the presence of a noninfective indication and if an implant of a new lead is planned, I perform a venography through an antecubital vein in order to assess venous patency and visualize the zone where a safe and effective venous puncture can be performed. In the presence of venous patency, I prefer creating a new access into the vein rather than inserting the new lead inside the sheath after lead removal. In this way, it is possible to avoid a risky lead position (in case of subclavian crush, for example), and the positioning of the new lead is easier outside of the fibrous endovascular tunnel. The intraoperative checklist is then completed.

With appropriate attention to patient preparation, FDG PET in diabetics for assessing viability reportedly has high sensitivity (92%) and specificity (85%) [96]. A perfusion FDG mismatch on PET in diabetic patients reliably identifies high risk for cardiac death with medical treatment compared to revascularization [97].

Patient preparation includes evaluation of clinical indications, and nutritional conditions (i.e. fed state, fast state, fasting duration) must be precisely defined. The patient must be fully informed of all procedures and at rest prior to blood sampling or invasive procedure. If fasting is required, the fast is scheduled for 24 h, but can be interrupted. Beginning at night, sampling is performed at 2,15, 20 and 24 h of the fast. 

Plasmapheresis is an intermediate form of therapy for myasthenia gravis, having effects that last longer than those of cholinesterase inhibitors but shorter than those of thymectomy. Improvement in myasthenic symptoms often occurs, but its duration is unpredictable. Plasmapheresis usually is reserved for patients who have severe symptoms resistant to other therapeutic approaches or for patients preparing for thymectomy. 

The effect of low-density micronized crospovidone (e.g. Kollidon CL-M) in stabilizing suspensions can also be partly explained in terms of Stokes law Its particle size is very fine (see Section 3.2.2), its bulk density low and its density in water also low as a result of swelling. The product differs in these properties from the coarser products and other micronized types which have a higher bulk density with a similar swelling volume, and make it useful as an auxiliary for oral and topical suspensions for reducing sedimentation and improving redispersibility [98]. The same applies, whether the commercial product is a suspension or a dry syrup, or instant granules from which the patient prepares an oral suspension. 

Patient preparation required—relevance of diurnal variation... 

The setting of a research study may or may not be the same as that of the individual patient. The evidence from a study may be unreliable when differences exist in age, sex, ethnic origin, lifestyle, prevalence of the disease in the population, or prevalence of comorbidities. Transferability of study results may also be affected by analytical variables, such as patient preparation (effects of fasting, posture, exercise, and biological variation) and method performance (accuracy and precision). 

It is possible to substitute the coefficient of variation for the standard deviation in the above equation. If the conditions of patient preparation, sample collection, and sample handling are standardized, preanalytical variation is minimized and the total variation is then determined by the combined influence of the analytical and intraindividual variations, thus ... 

The control of preanalytical conditions or variables, such as test requests, patient preparation, patient identification, specimen acquisition, specimen transport, specimen processing, specimen distribution, preparation of work lists and logs, and maintenance of records (see Chapters 1 and 17). ... 

Laboratory tests are affected by many factors, such as recent intake of food, alcohol, or drugs, and by smoking, exercise, stress, sleep, posture during specimen collection, and other variables (see Chapter 17). Proper patient preparation is essential for the test results to be meaningful. Although responsibility for this usually resides with personnel outside the laboratory, the laboratory must define the instructions and procedures for patient preparation and specimen acquisition. These procedures should be included in hospital procedure manuals and should be transmitted to patients in both oral and written instructions. Compliance with these instructions is monitored directly when the laboratory employs its own phlebotomists. Specific inquiry should be made regarding patient preparation before specimens are collected, and efforts should be made to correct noncompli-ance. For tests in which standardization of the collection is very important (such as for plasma catecholamines), specimens should be collected in a controlled environment, such as a clinical testing unit. 

D. Specimen List type of specimens that can be used and recommended volume and minimum volume. Indicate conditions that render the specimen unacceptable, such as hemolysis or lipemia. List patient preparation procedures. Provide instruction for specimen handling before testing.

A pharmacy technician is an individual who assists in pharmacy activities that do not require the professional judgment of a pharmacist. For example, pharmacy technicians may accept orders from patients, prepare labels, enter drug information into the pharmacy s computer system, and retrieve medications from inventory. As pharmacists assume an increasing number of clinical roles, pharmacy technicians are taking more and more responsibility for distributive functions in pharmacies in all settings.

Esophagogastroduodenoscopy (EGD) is used to examine the esophagus, stomach, and duodenum. Patient preparation for EGD includes fasting for 6 to 8 hours prior to the procedure and the administration of sedatives and topical anesthetics. Common indications may be either diagnostic or therapeutic in nature, and include evaluating suspected upper GI bleeding, obstructions, upper abdominal pain. 

Edncation, commnnication, and planning are the key nonphar-macologic components of caring for an AD patient. Preparation in the early stages of illness will lessen some of the caregiver stress as the illness progresses. 

Mild physical exertion (S60) and participation in normal sports activities (K21) are without effect on serum alkaline phosphatase. Prolonged bed rest causes no significant changes (H6, H22). Even a marathon run produced a mean increase of only 25% (R22), while the assumption of the erect posture for 30 minutes caused only minor rises (D15, S62). Complex protocols for patient preparation are therefore unnecessary from a clinical point of view.
