Although most medical careers do require a substantial amount of education, graduates of medical programs can usually look forward to some of the highest paying jobs in relation to their peers. Medical knowledge is always in demand, and medical careers are not usually motivated by the state of the economy.

Since there are so many different disciplines in medicine, it’s easy to specialize in what interests you most, and even branch out within that specialty. For example, if you decide to focus on the field of medical research, you could lead clinical trials that have a genuinely positive impact on the health of current and future generations.

There are many compelling reasons to think about entering the medical field. The best way to find out if it’s a good fit for you is to find someone who currently works in medicine and ask if you can volunteer to shadow them. This way you can benefit from a mentorship. The real-life experience you gain will help you determine whether to continue pursuing this career.

The earliest medical technology may have been the stick used to try to beat out the devils that people thought were causing some guy’s rash. Over time, with improvements in technology and our understanding of the body, medical technology has grown much more advanced.

Over 4600 years ago, ancient Egyptians were performing simple surgeries. Circumcision is believed to have been practiced, as is the use of artificial cosmetic prosthetics.

A thousand years ago, Abulcasis wrote a medical text that described surgical instruments, plaster casts, and inhaled anesthetics. Medical tech became advanced enough to allow limited eye surgeries. Between eight and six hundred years ago, convex and concave lens spectacles were used to correct vision.

In the past two hundred years, medical technology has allowed us to view or take measurements of the body’s interior. The stethoscope was invented in 1816. In the 1850s, the inventions of the ophthalmoscope and laryngoscope allowed physicians to peer inside the eyes and throat. A few decades later, x-rays were used in medical imaging.

In the first decades of the 20th Century, electrocardiography and electroencephalography were discovered. The 1940s saw the introduction of the dialysis machine and intraocular lens. The 1960s brought powered prosthetics, cochlear implants, and balloon catheters. By the 1970s, medical technology allowed for laser eye surgery and liposuction, and capsule endoscopy came in the 1980s. Recent advances in medical tech include the artificial liver and telesurgery.

Medical technology has advanced and evolved from very simple instruments to lasers and the bionic eye. We’re still waiting for the dermal regenerator from Star Trek, but given where medical tech is now, even that can’t be far off.

Although you may not have heard of it, nanotechnology is set to revolutionize the entire field of medicine. Nanotechnology is based on the must cutting edge research and technology. Scientists are working to create machines that function on the atomic level. Scientists are using this technology to create everything from super strong building materials to the most complex computer chips. However, naonmedicne as a branch of nanotechnology has perhaps the farthest reaching implications.

The most basic and immediate advances possible in nanomedicine are in imagining and drug delivery. Traditional imagining is often done with a lightly radioactive isotope which the patient drinks and then it circulates through the body. It causes the targeted organ to light up when placed in the various imagining machines. However, a large concentration must be used to insure that the targeted area lights up and so much is wasted through other parts of the body. Pharmaceuticals function in a similar way. The medicine hits the targeted part of the body, but much is wasted throughout the rest of the body.

Nanotechnology can assist this. Imagining agents and pharmaceuticals can include nanomachines which are programmed to guide the substance to the appropriate part of the body. This targeted deployment not only reduces the amount of the substance necessary to achieve either imagining or an active dose, but also insures it doesn’t spread to other parts of the body which may complicate other conditions. These advances are just around the corner and could increase effectiveness and reduce costs of treatments.

However, the most startling advances of nanomedicine lie in the future. Through nanomachines, health experts will be able to target cancer and remove it with programmed machines. Scientists have already run experiments with using nanomachines to rebind two pieces of meat with a laser. This could entail the end of stitches and sutures because wounds could be instantly closed through nanomachines. Finally, they’re even working on nanomachines which rebuild cells which could directly target diseased cells and chemical or enzyme deficiencies.

Addiction to drugs or alcohol destroys lives. It can tear families apart, cause financial ruin, result in job loss, land a person in jail, and even end in the death of the addict or someone else because of the addict’s poor choices. For that reason, drug and alcohol treatment is crucial in helping a person overcome an addiction.

One type of drug and alcohol treatment is an inpatient center. This type of recovery center provides support, monitoring, and therapy by addiction specialists and professionals. Because the beginning part of recovery is frequently the hardest, inpatient centers are helpful for a number of reasons, including:

• Clean environment. Inpatient drug and alcohol treatment centers provide an environment free from temptation. When trying to recover on their own, addicts frequently face offers of drugs and alcohol from friends, dealers, and so forth. At an inpatient center, that access is removed.

• Professional help through the detox. The beginning phase of recovery is the detox period, which is physically and emotionally draining and taxing. Many people who attempt to recover on their own don’t get past this initial phase. With an inpatient center, trained professionals and doctors oversee the process, so it is gradual and occurs in a healthy manner.

• Monitoring. Assistance and monitoring through the recovery process is available to residents of inpatient centers at all hours of the day. This can range from doctors to therapists.

• Coping techniques. At inpatient facilities, addicts learn how to cope with and deal with their addictions so they know how to handle temptation should they face it once they are released. They essentially get a new outlook on life in a program that promotes healing and is free from distractions. They learn about healthy ways to deal with stress. Instead of turning to a substance for comfort or escape, they will have new techniques for dealing with their anger or frustration.

Blood transfusions raise numerous difficulties. The most obvious one entails finding a match. Antigens which determine blood type can cause life threatening reactions among patients. Moreover,determining blood type can cost precious time in trauma cases. In addition, other undetectable diseases may contaminate blood which might contribute to further complications. Blood has a relative short life span and can spoil quickly. All of these problems have lead to research into various synthetic blood technologies. These are currently undergoing clinical trials, but maybe be available to hospitals relatively soon.

Volume expanders don’t carry out any of the key functions of human blood, but they can help with stabilization of trauma patients. The loss of pressure remains one of the most dangerous aspects of blood loss. Blood is highly oxygenated and so even a reduced amount can continue to sustain the human body in an inactive state. However, a loss of pressure reduces the ability of the heart to pump oxygenated blood around the body. Synthetic volume expanders don’t run the danger of immunologic reactions because it contains no antigens. One can maintain blood pressure through the crisis before switching to a traditional blood transfusion.

Synthetic platelets provide the next exciting field of research. Platelets help the body stop bleeding by attaching themselves around the wound until it’s closed over. Synthetic platelets can be added to an intravenous solution to help increase clotting. In addition, it has longer shelf life than traditional blood and can be stored as a powder. This increased clotting power can make all the difference from the trauma ward and operating room. Synthetic clotting agents are right around the corner, but more complex forms of synthetic blood are still off in the distance.

One of the greatest difficulties in replicating human blood lies in oxygen transportation because most materials which hold oxygen well don’t give it up well. However, there has been some success with Hemoglobin based treatments, but they’re still in clinical trials with many of the most advanced treatments being canceled to do problems with toxicity. Nevertheless, cheap synthetic blood stands as a possibility within our lifetime.
