It would be difficult to teach someone the complexities of medicine without a good understanding of the basics order cozaar us diabetes medications brand names. In addition to modern medical knowledge order genuine cozaar diabetes insipidus presentation, if you are planning for a multi-generational catastrophe then you need to study medical history generic calan 80mg otc. The practice of medicine in the th th 18 and 19 Century provides, in our opinion, what we may realistically expect in terms of a technological level in medicine with our modern knowledge superimposed over the top. Look at how things were done, and with what instruments, what medications where used, and how; what were the medical problems encountered? Much from that time is simply wrong and reflects the ignorance of physiology and pathology of the times but there is much to learn, and when approached with modern knowledge it is easy to identify what is useful information and what is not. An interesting way to appreciate the medical problems of the time is by looking at the causes of death during that period; this gives some insight into likely serious medical problems in this sort of scenario now. Below are some of the commonest causes of th death in early 19 Century in Australia. In addition to showing causes of death they also show some of the limited medical understanding of the time: • Trauma (including drowning and burns) – deaths from drowning and burns appear to have occurred with frightening frequency. There were also a large number of trauma deaths – both as a consequence of (mostly) farming accidents and violence. While covering a number of different diagnosis for the most part it referred to heart failure and commonly followed episodes of severe chest pain although at the time this wasn’t recognised for what it was – a myocardial infarction • Abdominal distemper – this was a syndrome characterised by severe abdominal pain, abdominal rigidity, fevers, and death. A significant number of cases were probably appendicitis although it is likely that pancreatitis, liver disease (from alcohol abuse), and gallbladder infections accounted for a number of cases. Again, more recently the term referred to typhoid fever, prior to this it referred to any dysentery. They divided them into one of three groups: • those conditions that can be treated • those that can be contended with • those that cannot be treated It is simple but surprisingly useful because in an austere situation it gives a framework to classify what you can do for your patients; those you can treat and cure, those that you can palliate or make comfortable (until they die or get better), and those that you can do nothing for or where your intervention is likely to make things worse. You need to convey a realistic expectation to your patients of what you will be able to achieve and this provides a simple framework. Lifestyle/Public health Lifestyle: Prior to any disaster it is worth considering what you can do to improve your own and your group’s health. Prevention of diseases such as heart disease, strokes, and diabetes is much better than attempting to treat them in an austere survival situation. You should ensure that all members of your group have their vaccinations up to date especially tetanus, measles, diphtheria, and polio. Preventive medicine: A large proportion of the disease burden in the past is related to poor public health and preventive medicine. For the most part it was related to ignorance of the role of bacteria in causing disease. Key elements of preventive medicine and infection control include: • Clean drinking water – uncontaminated by sewage and waste water • Hand washing – soap production is a priority.
