Sterilization and Disinfection Introduction Microbes are ubiquitous and many microorganisms are associated with undesirable consequences erectile dysfunction causes tiredness 100mg viagra capsules visa, such as food spoilage and disease erectile dysfunction injection therapy buy viagra capsules 100 mg visa. Therefore erectile dysfunction protocol download pdf order 100mg viagra capsules free shipping, it is essential to icd-9-cm code for erectile dysfunction purchase viagra capsules 100mg line kill a wide variety of microorganisms or inhibit their growth to minimize their destructive effects. The goal is twofold: (a) to destroy pathogens and prevent their transmission and (b) to reduce or eliminate microorganisms responsible for the contamination of water, food, and other substances. Examples of antisepsis include (a) preparing the skin before surgical incisions with iodine compounds, (b) swabbing an open root canal with hydrogen peroxide, and (c) ordinary hand washing with a germicidal soap. Sanitization is any cleansing technique that mechanically removes microorganisms (along with food debris) to reduce the level of contaminants. Cooking utensils, dishes, bottles, cans, and used clothing that have been washed and dried may not be completely free of microbes, but they are considered safe for normal use. Air sanitization with ultraviolet lamps reduces airborne microbes in hospital rooms, veterinary clinics, and laboratory installations. It is often necessary to reduce the numbers of microbes on the human skin through degerming procedures. This process usually involves scrubbing the skin or immersing it in chemicals, or both. It also emulsifies oils that lie on the outer cutaneous layer and mechanically removes potential pathogens from the outer layers of the skin. Examples of degerming procedures are (a) surgical hand scrub, (b) application of alcohol wipes to the skin, and (c) cleansing of a wound with germicidal soap and water. The concepts of antisepsis and degerming procedures clearly overlap, since a degerming procedure can be simultaneously treated as an antiseptic and vice versa. Definition of Frequently Used Terms Sterilization is defined as a process by which an article, surface, or medium is freed of all living microorganisms either in the vegetative or in the spore state. An object cannot be slightly sterile or almost sterile; it is either sterile or not sterile. Although most sterilization is performed with a physical agent, such as heat, a few chemicals called sterilants can be classified as sterilizing agents because of their ability to destroy spores. A germicide, also called a microbicide, is any chemical agent that kills pathogenic microorganisms. A germicide can be used on inanimate (nonliving) materials or on living tissue, but it ordinarily cannot kill resistant microbial cells. Any physical or chemical agent that kills "germs" is said to have germicidal properties. Disinfection refers to the use of a chemical agent that destroys or removes all pathogenic organisms or organisms capable of giving rise to infection. It is important to note that disinfectants are normally used only on inanimate objects because they can be toxic to human and other animal tissue, when used in higher concentrations. Disinfection processes also remove the harmful products of microorganisms (toxins) from materials. Examples of disinfection include (a) applying a solution of 5% bleach to examining table, (b) boiling food utensils used by a sick person, and (c) immersing thermometers in an isopropyl alcohol solution between use. In modern usage, sepsis is defined as the growth of microorganisms in the body or the presence of microbial toxins in blood and other tissues. The term asepsis refers to any practice that prevents the entry of infectious agents into sterile tissues and thus prevents infection. Physical Methods of Sterilization Physical methods of sterilization include the following: 1. Sunlight Heat Filtration Radiation Sound (sonic) waves Sunlight Direct sunlight is a natural method of sterilization of water in tanks, rivers, and lakes. Bacteria present in natural water sources are rapidly destroyed by exposure to sunlight. As a rule, higher temperatures (exceeding the maximum) are microbicidal, whereas lower temperatures (below the minimum) tend to have inhibitory or microbistatic effects. In fact, it can contain 20,000 microbes per milliliter or more, which explains why even an unopened carton of milk will eventually spoil on prolonged storage. Newer techniques have now been used to produce sterile milk that has a storage life of 3 months. Sterilization at a temperature of 100°C: Sterilsation at a temperature of 100єC includes (a) boiling and (b) steam sterilizer at 100°C.

Streak Culture Streak culture is the most useful method for obtaining discrete colonies of the bacteria erectile dysfunction treatment unani buy 100mg viagra capsules amex. It is carried out by streaking on the surface of a solid media plate using a platinum or nichrome loop of 2­4 mm diameter erectile dysfunction treatment in kolkata viagra capsules 100 mg online. In this method erectile dysfunction treatment homeopathy order 100 mg viagra capsules fast delivery, a loopful of the inoculum is placed near the peripheral area of the plate erectile dysfunction garlic cheap 100 mg viagra capsules free shipping. The inoculum is then spread with the loop to about one-fourth of the plate with close parallel strokes. From the primary inoculum, it is spread thinly over the plate by streaking with the loop in parallel lines. The inoculated culture plate is incubated at 37°C overnight for demonstration of colonies. Confluent growth occurs at the primary inoculum, but becomes progressively thinner, and well-separated colonies are demonstrated on the final streaks of the inoculum. Single isolated colonies obtained by this method are very useful to study various properties of bacteria. Streak culture is the most useful method for obtaining discrete colonies of the bacteria. Stroke Culture Stroke culture provides a pure growth of bacteria for carrying out slide agglutination and other diagnostic tests. Stab Culture Stab culture is prepared by stabbing the medium in tubes with a long, straight wire and incubating at 37°C. Lawn Culture the lawn culture provides a uniform layer of bacterial growth on a solid medium. It is carried out by flooding the surface of the solid media plate with a liquid culture or suspension of bacteria, pipetting off the excess inoculum, and finally Key Points Stab culture is frequently used for: Maintaining stock cultures. Liquid Culture Liquid culture is prepared in a liquid media enclosed in tubes, flasks, or bottles. The medium is inoculated by touching with a charged loop or by adding the inoculum with pipettes or syringes and incubating at 37°C, followed by subculture on to solid media for final identification. The failure to do so may have serious consequences, such as amputation, organ failure, sepsis, meningitis, and even death. Specimen Collection Specimens frequently used for anaerobic culture include: Blood, bile, bone marrow, cerebrospinal fluid, direct lung aspirate, and tissue biopsy from a normally sterile site; Fluid aspirated from a normally sterile site, such as a joint; Pus specimens from dental abscess, burn wound, abdominal or pelvic abscess; and Specimens from knife, gunshot, or surgical wounds. Collection of a contamination-free specimen and protecting it from oxygen exposure during collection form the mainstay of anaerobic culture. The specimens need to be obtained from an appropriate site without contaminating the sample with bacteria from the adjacent skin, mucous membrane, or tissue. Abscesses or fluids are usually collected by using a sterile syringe and is then tightly capped to prevent entry of air. Tissue samples are placed into a degassed bag and sealed, or into a gassed out screw top vial that may contain oxygen-free prereduced culture medium and tightly capped. The specimens need to be plated as rapidly as possible onto culture media for isolation of bacteria. Chapter 43 Key Points Liquid culture is specifically used: For blood culture and for sterility tests, where the concentration of bacteria is expected to be small; For culture of specimens containing antibiotics and other antibacterial substances, as these are rendered ineffective by dilutions in the medium; and When large yields of bacteria are required. A major disadvantage of liquid culture is that it does not provide pure culture of the bacteria and also the bacterial growth does not exhibit special characteristic appearances. Anaerobic Culture Obligate anaerobes are bacteria that can live only in the absence of oxygen. These anaerobes are killed when exposed to the atmosphere for as briefly as 10 minutes. Anaerobic bacterial culture is a method used to grow anaerobes from a clinical specimen. Culture and identification of anaerobes is essential for initiating appropriate treatment.

The determinants of the first delay are related to erectile dysfunction and stress buy 100mg viagra capsules amex the individual circumstances of the women and their families erectile dysfunction education buy viagra capsules 100 mg lowest price, who must first recognize that care is needed and then be able to erectile dysfunction medication insurance coverage order viagra capsules 100 mg without prescription access transport or money to erectile dysfunction overweight purchase 100mg viagra capsules amex travel to facilities. The determinants of the second delay concern the physical environment, the type of transport, and the quality of the roads, as well as the performance of the referral system between facilities. The determinants of the third delay are related to quality of care, such as the number and training of staff members and the availability of blood supplies and essential equipment. Although the actions and characteristics of women and families can influence the length of the third delay, for example, by helping to mobilize elements of the surgical kits for cesarean delivery by purchasing missing supplies in pharmacies (Gohou and others 2004), most of the determinants of the third delay are related to service provision. It does not include the concept of primary prevention (avoid pregnancy) and secondary prevention (avoid complications once pregnant). It ignores family planning, noncommunicable chronic diseases, antenatal care, and postpartum care. Implicitly, it also assumes that complications arise at home, where women intend to give birth, whereas increasing numbers of women deliver in facilities (Filippi and others 2009). In addition, it does not consider the newly identified "fourth delay," which arises when women are discharged unwell or chronically ill from facilities and die at home during the postpregnancy period or in the next pregnancy (Pacagnella and others 2012; Storeng and others 2012). The concept of freedom refers to the right of women to control their bodies, including their reproductive options, and to have access to acceptable and effective family Levels and Causes of Maternal Mortality and Morbidity 63 planning services, including safe abortions. Entitlements are concerned with access to good quality services, which must be evidence based and respectful and emphasize equity in access for all women who need care, whether they are rich or poor, married or single. Quantitative models suggest that preventing pregnancy with contraception has a bigger role to play in reducing maternal mortality than does inducing abortion when pregnant with an unintended pregnancy (Singh and Darroch 2012). However, although access to safe abortion techniques has become easier with the availability of medical abortion, including on the black market from drug sellers or the Internet in countries where abortion is illegal, many women still die because they cannot access safe abortion services (Ganatra and others 2014). The distal determinants of fertility and unwanted pregnancy are broadly similar to the distal determinants of maternal health, with their emphasis on culture, poverty, and education, but their proximate determinants are somewhat different, with a focus on fecundability and marriage patterns (Bongaarts 1978) and, in the case of unwanted pregnancies, an emphasis on the needs of younger and unattached women. Several studies, mostly qualitative, highlight episodes of rampant disrespect and abuse of pregnant women or women in labor in some maternity units (Hassan-Bitar and Wick 2007; Silal and others 2012). Health System Factors the maternal mortality level is one of the best criteria for assessing the relative performance of health systems. One example of a coverage indicator of the continuum of care is skilled birth attendance, which is particularly inequitable. Health system classifications are helpful in highlighting the barriers or in facilitating the factors that many women meet when they seek care during pregnancy, childbirth, or emergency situations. These classifications complement the three delays model because they go beyond emergency obstetric care. All of these building blocks are determinants of the coverage and quality of care that women receive across the continuum of care. Country case studies describe the relative importance of these building blocks or equivalent groupings in understanding progress in maternal health (McPake and Koblinsky 2009). Progress has also been made for skilled birth attendance since 1990 (median coverage of 57 percent), emergency obstetric care (as measured, for example, by the cesarean section rate, and by the density of emergency obstetric care facilities per birth or population), and postnatal care for mothers (median coverage of 41 percent). For example, the welldocumented decline in maternal mortality in Bangladesh may be related to the availability of emergency obstetric care interventions and fertility decline, but it is also likely to be linked to the increased participation of women in the labor force. Several ecological studies of maternal mortality have shown the relationship between maternal mortality and skilled birth attendance, as well as to gross national product, health care expenditures, female literacy, population density, and access to clean water (Buor and Bream 2004; Montoya, Calvert, and Filippi 2014). Observational studies have shown inadequate levels of hygiene in many maternity facilities (Benova, Cumming, and Campbell 2014), with direct health impacts on mothers, newborns, and care providers (Mehta and others 2011). The reasons are multifactorial and include poor infrastructure; inadequate equipment and supplies; and poor practices by care providers and cleaners as a result of inadequate knowledge, attitudes, motivation, and supervision (Campbell and others 2015). Interventions to address these constraints go beyond the health sector, particularly for water and sanitation (Shordt, Smet, and Herschderfer 2012). Timely access to care and the difficulties in obtaining motorized transport, as well as challenging topography and inadequate and poorly maintained roads, are important barriers to care. Gabrysch and others (2011) demonstrate that in Zambia, the odds of women being able or choosing to deliver in a health facility decreased by 29 percent with every doubling of distance between their home and the closest facility. They conclude that if all Zambian women lived within 5 kilometers of health facilities, 16 percent of home deliveries could be averted. The proportion of hemorrhage and hypertension deaths found globally remains high despite established interventions to prevent and treat direct causes of maternal death (see chapter 7), such as active management of the third stage of labor. With the data available, it is not possible to determine if this high proportion is the result of a failure to implement policies and therefore quality of care, if there is a shift toward antepartum hemorrhage, or if misclassifications of abortion and obstructed labor are erroneously increasing the hemorrhage category.
