Aspergillus detection in bronchoscopically acquired material: significance and interpretation. The spectrum of Fusarium an infection in immunocompromised sufferers with haematological malignancies and in nonimmunocompromised sufferers: a single establishment experience over 10 years. Guidelines for stopping infectious complications among hematopoietic cell transplantation recipients: a global perspective. It has been identified for decades that a granulocyte count of less than 500 cells/mm3 (and especially one hundred cells/mm3) is related to an elevated danger of severe bacterial and fungal infections. Indeed, a survey on fever during neutropenia in youngsters with cancer confirmed the presence of extreme infectious problems. Finally, new and peculiar features emerge with the utilization of biologic response modifiers, which have turn into part of many chemotherapeutic regimens and pose new challenges that must be thought of. However, compared with earlier editions of Principles and Practice of Infectious Diseases, the most important change in the updated model of this chapter is represented by the phenomenon of rising antibiotic bacterial resistance worldwide, which also clearly impacts the administration of infections in most cancers sufferers. This is radically altering our ability to forestall and treatment infections in the immunocompromised. As proven in Table 310-1, the medical method to a most cancers patient with indicators and signs of an infection is multifactorial. Before planning a rational administration intervention, physicians should answer a number of crucial questions concerning the sort and stage of the underlying illness and the clinical presentation, to make a considerate and effective intervention. Among others, elements potentially related to the presence of highly resistant bacterial strains should currently be very rigorously considered. Infections in most cancers patients have often been thought-about nosocomial, although these patients are sometimes cared for as outpatients and even on a home-care foundation. In fact, a research on infectious issues in 113 adults receiving therapy for acute hematologic malignancies confirmed that 91% of 223 infectious episodes were actually related to the sort of care sufferers had obtained, but solely 42% of the episodes were actually "nosocomial" in origin. In the next sections, the epidemiology and management ideas of infections in most cancers sufferers shall be described. Has the catheter been manipulated (including infusions) within a number of hours before the onset of fever Different medication might give different type of immunosuppression and favor different infectious problems. Previous transplantation may end in long-term immunodeficiency, notably if immunosuppressive therapy is continued. The information of local epidemiologic data on antimicrobial susceptibility is necessary for an accurate selection of empirical therapy. In patients susceptible to an infection brought on by resistant bacteria, notably if neutropenic, initial empirical remedy should cover these pathogens. Epidemiology of antibacterial resistance varies worldwide; thus, patients coming from areas endemic for resistant micro organism must be handled accordingly. The presence of mucositis is suggestive of an infection with pathogens from oral flora or gastrointestinal tract. The pain could assist to find formation of abscesses or indicate presence of a regionally invasive course of, similar to pulmonary aspergillosis. Breakthrough infections are attainable, and fever throughout prophylaxis must be considered as failure of prophylaxis, except confirmed otherwise. The occurrence of a bacterial/fungal/viral infection throughout particular prophylaxis might influence the selection of empirical remedy, depending on the drug used for prophylaxis. Knowledge of local epidemiology, together with susceptibility pattern, is necessary for a correct diagnostic and therapeutic administration. However, the big majority of epidemiologic information about these sufferers come from research on empirical antibiotic remedy or prophylaxis, by which sufferers have been selected based on inclusion and exclusion criteria. Thus, this approach could be inadequate to describe the precise epidemiologic state of affairs in real life. Epidemiologic data on the incidence of infections are usually reported as percentages of occasions over a given number of patients or treatment programs, with out adjusting throughout the period at risk. This might be incorrect because the duration of publicity is crucial to perceive the medical impression of a given phenomenon. Tables 310-2 and 310-3 report the epidemiology of febrile episodes, bacteremia, and invasive mycoses in most cancers sufferers. Additional elements are represented by the phase of chemotherapy and the standing of the neoplastic illness, with larger incidence of infectious complications in patients receiving remission-induction and rescue chemotherapy, in contrast with maintenance or consolidation first-line remedies. Patients with chronic leukemia or multiple myeloma might represent a peculiar group because of the function performed by means of the new biologic response modifiers (imatinib, desatinib, rituximab, alemtuzumab, and so forth. These new drugs have the potential to modify the danger profiles for infectious issues, with an rising danger of infections also attributable to beforehand uncommon pathogens, such as Pneumocystis jirovecii and various viruses.

Rapid weight reduction throughout this time poses theoretical dangers or intrauterine etal-growth restriction and nutritional deprivation. However, as weight is lost, ertility charges overall seem to be improved, and dangers or pregnancy enhance (Merhi, 2009). However, the contraceptive patch (OrthoEvra) is less e ective in those weighing greater than ninety kg (Zieman, 2002). Speci c to those with malabsorptive bariatric surgical procedure varieties, oral contraception e cacy may be lower because of poor absorption (Centers or Disease Control and Prevention, 2013). Last, due to its threat or related weight achieve, depot medroxyprogesterone acetate (Depo-Provera) may be an unpopular alternative in women making an attempt to lose weight. Table 1-7 illustrates recommended guidelines to direct therapy or obese or overweight women. According to the American Heart Association, appropriate options are diets with 1200 to 1500 kcal/day or diets that incorporate a 500 or 750-kcal/d de cit (Jensen, 2014). No single diet plan is espoused as the gold normal or each affected person, and the perfect routine is one that might be adhered to . In addition to diet and train, pharmacologic or surgical choices could additionally be implemented or selected obese sufferers. First, orlistat (Xenical) is a reversible inhibitor o gastric and pancreatic lipases and leads to a 30-percent blockage o dietary at absorption (Henness, 2006). This drug is prescribed as 120-mg capsule taken orally three times daily with meals however can also be out there over-the-counter in 60-mg capsules (All), also taken thrice day by day. Associated malabsorption can result in de ciencies o the at-soluble nutritional vitamins A, D, E, and K, and all patients ought to obtain a daily complement enriched with these vitamins. Severe liver injury has been reported not often, and new labeling ref ects this risk (Food and Drug Administration, 2010). Another treatment, lorcaserin (Belviq) is a serotonin 2C receptor agonist used to suppress urge for food (Fidler, 2011; Smith, 2010). This drug has etotoxicity potential and prescribing suppliers take part in a Qsymia Risk Evaluation and Mitigation Strategy program.

The risk o hypertension will increase with age and is elevated or black ladies compared with these o other races (Go, 2014). Chronic hypertension will increase the risks or myocardial in arction, stroke, congestive coronary heart ailure, renal disease, and peripheral vascular disease. Moreover, chronic hypertension and its potential therapies might restrict contraception decisions or some girls. T us, gynecologists must be amiliar with standards used to diagnose hypertension. Although many may choose to re er their sufferers or therapy o hypertension, gynecologists must be aware o goal targets and long-term dangers associated with this disease. For adult screening, the American Heart Association (2014) recommends blood strain evaluation beginning at age 20 and evaluation repeated every 2 years i initially normal. With screening, blood pressures are greatest taken with a girl seated in a chair with the examined arm resting on a desk, at the degree o the heart. Ideally, the patient has been in a place to rest quietly or a ew minutes previous to measurement and to have re rained rom tobacco and ca eine use immediately previous to testing. An appropriately sized cu is selected, and the cu bladder should encircle a minimal of eighty p.c o the arm. Hypertension is recognized i readings are elevated on no much less than two separate o ce visits over one or more weeks. Notably, girls with prehypertension are at signi cantly elevated danger o creating hypertension later (Wang, 2004).

Must be calculated with a 24-hour urine assortment, which is inconvenient for patients and often incomplete. Overall, more accurate and now extra generally used than Cockcroft-Gault formulation or 24-hour urine measurement of creatinine clearance. T felt well till 3 days in the past, when he had a shaking chill followed by a fever and the onset of a cough productive of rusty coloured sputum. His previous medical historical past is notable for well-controlled hypertension and prostate cancer treated with radiation remedy 5 years in the past. Lung exam is notable for decreased breath sounds and crackles on the proper lung base. Transient hypovolemia or hypotension causes prerenal azotemia, but prolonged hypotension results in renal ischemia. Urine is obtained prior to the fluid bolus and outcomes include urine sodium, forty mEq/h; urine chloride, 57 mEq/mL; urine creatinine, forty five mg/24 h, and urine urea nitrogen 250 g/24 h; urinalysis confirmed specific gravity, 1. Textbook Presentation the presentation ranges from asymptomatic (with discovery of an increased creatinine on routine laboratory testing) to symptoms of uremia, such as lethargy, nausea, delirium, seizures, edema, and dyspnea.

Toxin publicity (radiocontrast media, aminoglycosides, amphotericin B, cisplatin, Hgb, myoglobin, crystals, myeloma proteins) 3. Serum creatinine levels peak at three days postexposure and often return to baseline within 10 days. Hypoperfusion causes increased reabsorption of sodium, water, and urea by the tubules; if prolonged ischemia leads to tubular harm, the tubules can no longer enhance reabsorption, resulting in urinary sodium and urea loss. Urea reabsorption is much less affected by loop and thiazide diuretics than urine sodium. Can even be elevated with gastrointestinal bleeding, use of corticosteroids, intake of a high-protein diet, or elevated catabolism (postoperative or infection) b. One examine means that a mixture of findings (eg, confusion, nonfluent speech, dry mucous membranes, dry/furrowed tongue, extremity weakness, and sunken eyes) is highly predictive of hypovolemia. No evidence to help the use of loop diuretics, such as furosemide, or low-dose dopamine; each may actually be dangerous. Guidelines advocate 1 mL/kg/hour for 12 hours previous to and 12 hours following the procedure in inpatients; for outpatients and pressing procedures 3 mL/kg/hour for 1 hour previous to and 1�1. There are conflicting information on the advantages N-acetylcysteine; if used, give 1200 mg orally twice daily on the day previous to and the day of the process. Use an iso-osmolar or low-osmolar distinction agent; administer the lowest attainable dose of contrast. He returns to see you 2 weeks later, reporting that his osteoarthritis "flared" after so much time in bed, and he has been using celecoxib for reduction. Patients with irregular renal operate are on the highest danger for this complication, and such medications ought to be avoided.

Risk components for delayed initiation of medical care after diagnosis of human immunodeficiency virus. Young age predicts poor antiretroviral adherence and viral load suppression amongst injection drug users. Methadone, buprenorphine, and street drug interactions with antiretroviral medications. Prevalence and correlates of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis infections, and bacterial vaginosis amongst a cohort of young injection drug users in Baltimore, Maryland. The endorsement signaled an finish to the long-held belief that the publicity of natural material to air introduced in regards to the spontaneous generation of microorganisms, and the concepts of sepsis and asepsis became firmly established. A mere 3 years later, Joseph Lister demonstrated the unbelievable implications of antisepsis in his follow of orthopedic surgery. For the primary time in recorded history, main surgical procedures could be carried out with a reasonable expectation of main wound therapeutic and restoration. Essential enhancements for preventing and controlling wound sepsis have been offered by the antibiotic revolution of the Nineteen Forties, ushering in the extremely technical, extremely invasive, and highly profitable period of contemporary surgical procedure. As noted by McDermott and Rogers,1 the good achievements of the antibiotic era may be related, in the long term, to its important position in supporting the developments of recent surgery. Indeed, surgery as we know it at present could be unimaginable in an surroundings during which an infection was probably or, once established, untreatable. Despite the elemental function of antisepsis and antibiotics within the growth of recent surgical procedure, implementation of those discoveries in the apply of surgical procedure has not occurred without opposition. The early use of antibiotics for prophylaxis in surgical procedures was additionally questioned as revered academicians freely voiced their disapproval of antibiotic prophylaxis in clean surgical procedures. Therefore, it appeared believable that perioperative antibiotics may supplement aseptic strategies in containing the inevitable contamination of the operative wound. The second major discovering concerned the timing of the administration of the prophylactic antibiotic. As early as 1946, Howes6 had noted a correlation between the amelioration of an infection and the interval between the contamination of the injuries and the administration of antibiotics. Several years later, Miles and colleagues7 and Burke,8 working with a guinea pig model of wound an infection, demonstrated the exceptional brevity of the "window" of prophylactic efficacy. They noted that antibiotics given shortly before or on the time of bacterial inoculation of the subcutaneous tissue of the guinea pig produced a notable diminution in the size of the following wound induration, in contrast with lesions in animals not receiving antibiotic prophylaxis. By delaying the administration of antibiotics by solely three or four hours, resulting lesions had been identical in measurement to these of animals receiving no antibiotic prophylaxis whatsoever. Thus, "failures" of antimicrobial prophylaxis that had been noted in earlier medical studies were related to the fact that administration of preoperative antibiotics had been inappropriately timed. The efficacy of prophylactic antibiotics has now been verified for many major surgical procedures with all kinds of antimicrobials when care has been given to present adequate serum 3492. Perioperative antibiotics and aseptic strategies have turn into routine aspects of care in most main surgical procedures. State-ofthe-art aseptic approach has been associated with a dramatic drop in, but not the elimination of, this phenomenon. Even underneath laminar circulate working room environments, micro organism may be isolated from wound surfaces at the shut of the surgical procedure. Carbapenemresistant Multidrugresistant patient- and procedure-related danger components additionally contribute significantly to this risk (Table 318-2). Unusual and hard-toculture species, including nontuberculous mycobacteria, Nocardia spp. Modern methods of antisepsis can reduce but not remove the skin-associated micro organism of surgical patients. This limitation derives, partly, from the localization of as much as 20% of skin-associated micro organism in pores and skin appendages, corresponding to hair follicles and sebaceous glands. For contaminated procedures, wound pathogens regularly are among the many bacterial species that comprise the conventional flora of the viscus entered during the surgical process. Transmission from contaminated surgical instruments or surgical material, hematogenous seeding from preexisting an infection of a nonwound website, and contamination from both the pores and skin, mucous membranes, or clothes of operating room workers have been implicated as potential sources of microbial contamination.
The being pregnant is then evacuated by suctioning out the contents-suction curettage, by mechanically scraping out the contents-sharp curettage, or each. According to one evaluation, the use o suction curettage is superior i available (un�alp, 2010). In addition to intravenously or orally administered sedatives, success has been reported with paracervical lidocaine blockade, with or with out different analgesics (Renner, 2012). Perioperative antibiotic prophylaxis is also beneficial as described on web page 143. Data from American College of Obstetricians and Gynecologists, 2015; Templeton, 2011. Surgical Abortion Surgical pregnancy termination includes a transvaginal method by way of an appropriately dilated cervix. Rarely, pregnancies are evacuated transabdominally by both hysterotomy or hysterectomy. O transvaginal procedures, electric vacuum aspiration is essentially the most commonly used orm and is illustrated in Chapter 43 (p. Alternatively, handbook vacuum aspiration is done with an analogous cannula that attaches to a handheld syringe or its vacuum source. Menstrual Aspiration Aspiration o the endometrial cavity inside 1 to three weeks a ter a missed menstrual period has been re erred to as menstrual extraction, menstrual induction, immediate period, traumatic abortion, and mini-abortion. The process is finished using a exible 5- or 6-mm Karman cannula and hooked up syringe. The primary drawbacks are that the small pregnancy may be missed or an ectopic pregnancy may be unrecognized. Despite the possibility o lacking the merchandise, Paul and coworkers (2002) reported a 98-percent success fee with more than a thousand such procedures. Cervical Preparation For transvaginal evacuation, preoperative cervical ripening so tens and slowly dilates the cervix to reduce trauma rom mechanical dilatation. This preparation is usually related to much less ache, a technically simpler process, and shorter working times (Kapp, 2010). O strategies, hygroscopic dilators draw water rom cervical tissues and increase to gradually dilate the cervix. One kind is derived rom varied species o Laminaria algae which are harvested rom the ocean oor (Chap. Schneider and associates (1991) described 21 cases in which girls who had a hygroscopic dilator positioned modified their minds. O 17 women who selected to proceed their pregnancy, 14 carried to term, two delivered preterm, and one miscarried 2 weeks later. None su ered in ection-related morbidity, including three untreated girls with cervical cultures optimistic or Chlamydia trachomatis. In spite o this usually reassuring report, it appears prudent to presume irrevocability with regard to dilator placement and abortion. In the metaanalysis by Kapp (2010), ef cacy o these drugs was ound to be much like that o hygroscopic dilators. The commonest is misoprostol (Cytotec), which is used o -label, and sufferers are recommended accordingly (ang, 2013). The dose Manual Vacuum Aspiration this procedure is similar to menstrual aspiration however is used or early being pregnant ailures or elective termination up to 12 weeks. Some recommend that pregnancy terminations carried out within the of ce with this method be limited to 10 weeks because blood loss rises sharply between 10 and 12 weeks (Masch, 2005; West all, 1998). A ter this time, some recommend that osmotic dilators be positioned the day previous to or misoprostol given 2 to 4 hours be ore the procedure. A vacuum is created within the syringe attached to the cannula, which is inserted transcervically into the uterus. A ter this time, obtainable data-albeit much less robust-support surgical abortion as pre erable. Bleeding and cramping with medical termination could be signi cantly worse than menstrual cramps, thus sufficient analgesia, usually including a narcotic, is offered. Currently, solely three medicines or early medical abortion have been extensively studied. These are used either alone or in combination and include: (1) the antiprogestin mi epristone, (2) the antimetabolite methotrexate, and (3) the prostaglandin misoprostol.
First, medical and surgical disorders may provide a maternal-health indication or being pregnant termination. These embody persistent cardiac decompensation, pulmonary arterial hypertension, superior hypertensive vascular illness, diabetes with end-stage organ ailure, and malignancy. The interruption o pregnancy be ore viability at the request o the woman, however not or medical causes, is usually termed elective or voluntary abortion. From the Guttmacher Institute, Jones and Kavanaugh (2011) estimate that a 3rd o American women will have at least one elective abortion by age 45. The Court de ned the extent to which states might regulate abortion and dominated that rst-trimester procedures should be le t to the medical judgment o the physician. A ter this, the state may regulate abortion procedures in methods reasonably related to maternal health. Finally, subsequent to viability, the state could promote its interest within the potential o human li e and regulate and even proscribe abortion, except or the preservation o the li e or health o the mom. The 1976 Hyde Amendment orbids use o ederal unds to provide abortion services besides in case o rape, incest, or li e-threatening circumstances. Subsequently, many states handed laws that imposes counseling necessities, ready periods, parental consent or noti cation or minors, acility necessities, and unding restrictions. According to the Guttmacher Institute, forty one states set new limits on abortion throughout 2011 and 2012 (anner, 2012). The College (2013e) supports the authorized right o ladies to obtain an abortion prior to etal viability and considers this a medical matter between a woman and her physician. Knowledgeable and compassionate counselors should objectively describe and provide in ormation concerning these selections in order that a girl or couple could make an in ormed choice (Baker, 2009; empleton, 2011). The Accreditation Council or Graduate Medical Education mandated in 1996 that Obstetrics and Gynecology residency education embrace access to expertise with induced abortion. The American College o Obstetricians and Gynecologists (2014c) outlines legislative, institutional, and social limitations to abortion training and helps the use o "opt-out" packages. In these, abortion coaching is built-in as a normal part o the residency schedule, but residents with religious or moral objections can decline to participate. Ryan Residency raining Program was established in 1999 to improve residency training in abortion and amily planning. Disappointingly, a latest survey o United States residency applications decided that no abortion training was out there in 16 p.c o programs and that 30 % proceed to use the "opt-in" strategy (urk, 2014). Other programs train residents technical aspects through administration o early incomplete and missed abortions and thru being pregnant interruption or etal dying, extreme etal anomalies, and li e-threatening medical or surgical disorders (Steinauer, 2005). Freedman and coworkers (2010) rightly emphasize that abortion training should embody dialogue o the social, ethical, and ethical aspects o the process. By 2010, these have been situated in 22 departments o obstetrics and gynecology at educational centers nationwide. With outpatient abortion, capabilities or cardiopulmonary resuscitation and or instant trans er to a hospital have to be out there. First-trimester abortion can be per ormed both medically or surgically by a quantity of methods that are listed in Table 6-10. Distinctive eatures o every approach were reviewed by the American College o Obstetricians and Gynecologists (2009). Results with both surgical or medical strategies are comparable with these or spontaneous miscarriage as beforehand proven in in a position 6-4. Both have a high success rate-95 p.c with medical and ninety nine percent with surgical techniques. With medical remedy, surgical procedure is usually avoided as is the need or sedation (Table 6-11). Medical terminations have decrease average costs and will enable or extra privacy through the termination. However, medical abortion might lengthen or days up to a ew weeks, bleeding is normally heavier and less predictable, and incomplete abortion is extra widespread with medical versus surgical abortion (Niinim�ki, 2009; Robson, 2009). Likely or these reasons, only 10 percent o abortions in the United States are managed using medical strategies (empleton, 2011). It additionally emphasizes the necessity to provide standard-o care counseling and well timed re erral i suppliers have individual belie s that preclude pregnancy termination.
These molecules could be preserved, however, by utilizing a nonaqueous fixative for glycogen or by adding particular binding brokers to the fixative resolution that preserve extracellular carbohydrate-containing molecules. Soluble elements, ions, and small molecules are additionally misplaced during the preparation of paraffin sections. The ability of such anionic groups to react with a fundamental dye is known as basophilia [Gr. Many of these substances can be studied in particular preparations, generally with considerable lack of structural integrity. When they are often preserved and demonstrated by specific strategies, they provide invaluable details about cell metabolism, lively transport, and other important cellular processes. Water, a highly versatile molecule, participates in these reactions and processes and contributes to the stabilization of macromolecular construction by way of hydrogen bonding. At a barely acidic to neutral pH (5 to 7), sulfate and phosphate teams are ionized and out there for reaction with the basic dye by electrostatic linkages. At a low pH (below 4), only sulfate teams remain ionized and react with basic dyes. An acidic dye, similar to eosin, carries a internet negative charge on its colored portion and is described by the general formula [Na dye]. A basic dye carries a web positive charge on its coloured portion and is described by the overall formulation [dye Cl]. Basic dyes react with anionic parts of cells and tissue (components that carry a web adverse charge). Therefore, staining with basic dyes at a particular pH can be used to concentrate on particular anionic groups; as a outcome of the particular anionic teams are found predominantly on certain macromolecules, the staining serves as an indicator of those macromolecules. The fundamental dye then tends to dissociate from the tissue in the course of the aqueous answer washes between the two dye solutions. Acidic dyes react with cationic groups in cells and tissues, significantly with the ionized amino groups of proteins. Reactions of cell and tissue parts with acidic dyes are neither as particular nor as precise as reactions with basic dyes. For instance, three acidic dyes are used in the Mallory staining technique: aniline blue, acid fuchsin, and orange G. These dyes selectively stain collagen, ordinary cytoplasm, and red blood cells, respectively. In other multiple acidic dye strategies, hematoxylin is used to stain nuclei first, and then acidic dyes are used to stain cytoplasm and extracellular fibers selectively. The selective staining of tissue elements by acidic dyes is attributable to relative components such as the scale and degree of aggregation of the dye molecules and the permeability and "compactness" of the tissue. These substances include: � � � most cytoplasmic filaments, particularly those of muscle cells, most intracellular membranous elements and much of the in any other case unspecialized cytoplasm, and most extracellular fibers (primarily because of ionized amino groups). This histochemical methodology demonstrates and localizes carbohydrates and carbohydrate-rich macromolecules. The kidney tubules (T) are sharply delineated by the stained basement membrane surrounding the tubules. The underlying mechanism for metachromasia is the presence of polyanions throughout the tissue. When these tissues are stained with a concentrated primary dye answer, similar to toluidine blue, the dye molecules are close enough to form dimeric and polymeric aggregates. The absorption properties of those aggregations differ from those of the person nonaggregated dye molecules. Cell and tissue constructions which have high concentrations of ionized sulfate and phosphate groups-such as the ground substance of cartilage, heparin-containing granules of mast cells, and rough endoplasmic reticulum of plasma cells- exhibit metachromasia. Therefore, toluidine blue will seem purple to red when it stains these parts. Periodic acid cleaves the bond between these adjoining carbon atoms and forms aldehyde groups. These aldehyde groups react with the Schiff reagent to give a distinctive magenta color. Methods Aldehyde Groups and the Schiff Reagent the flexibility of bleached primary fuchsin (Schiff reagent) to react with aldehyde groups results in a particular purple colour and is the idea of the periodic acid�Schiff and Feulgen reactions. Again, the newly fashioned aldehyde teams react with the Schiff reagent to give the distinctive magenta color. It is used to show glycogen in cells, mucus in varied cells and tissues, the basement membrane that underlies epithelia, and reticular fibers in connective tissue.
Kelvin, 34 years: After a three-dose sequence, the efficacy in opposition to any G1 to G4 virus�associated gastroenteritis was 74% and against severe gastroenteritis was 98%. Understanding the pharmacokinetics of the varied antimicrobials used in perioperative prophylaxis is therefore vital to ensure adequate antibiotic levels at the surgical wound site throughout the complete process.
