61) Anesthesia
Language
English
Description
Anesthesia simply means a loss of sensation and usually of consciousness, typically needed in the event of surgery. This helps to keep a patient still, unable to feel pain, and safely unaware of the procedure taking place. This easy-to-understand overview of anesthesia helps patients understand what to expect and how to prepare for any procedure. The video includes visuals of actual equipment in an operating room setting.

In the era of Big Pharma, why are researchers looking more and more to nature-and the human body itself-to provide tomorrow's medical cures? This program illustrates how scientists are growing and harvesting pharmaceuticals from common plants and farm animals, attempting to replicate organs, and transferring much-needed islet cells to patients with diabetes. The next big breakthrough in medical care is as likely to come from a rainforest or a goat...

The ethical debate over embryonic stem cell use may have been rendered moot by pioneering research being conducted at the Walter and Eliza Hall Institute of Medical Research in Australia, where Dr. Perry Bartlett and his team have isolated stem cells within the human brain. In this program, Dr. Bartlett discusses in detail the different types of stem cells, what research is being done with them, and how their use will have a future benefit in rebuilding...

Now that we know that genes from different species are interchangeable, biotechnology is beginning to engineer superanimals-and patenting them. Behold the geep, part goat, part sheep, engineered to take advantage of the best traits of each. What are the scientific goals? And the social controls? This program looks at how some women are selecting the genetic profiles of the children they choose to bear, and at the ethical and economic dilemmas intrinsic...

If you had a near-death experience once, you will remember it for the rest of your life. This film looks at research conducted in Geneva that supposes this is all a trick of the brain, testing their theory with a patient who has had several near-death experiences. The knowledge gained through these experiments can help people with chronic diseases and psychological traumas.

This program offers a comprehensive overview of the CT or CAT scan. Computed tomography, or computerized axial tomography, uses X-rays and computers to look inside the body. A computer then analyzes the images taken and creates a three-dimensional view of the structures within. After viewing the typical CT imaging procedures shown here, patients will know what to expect and can thus set their mind at ease.

Because of constant use of disinfectants, a hospital is a place where only the fittest microbes survive, a dilemma that raises the stakes of even routine surgical procedures. This program looks at how germs develop partial or total antibiotic resistance and how researchers are pursuing new lines of attack to keep pace with these highly adaptive organisms. Computer imaging and electron microscopy help illustrate how Legionella bacteria adapt to harsh...

Whether it occurs in mild, moderate, or severe cases, hemophilia is a serious and sometimes frightening disease. This program explores the basic aspects of hemophilia and features case studies of patients who are successfully managing the condition. Illustrating the lack of specific blood proteins, or clotting factors, at the root of hemophilia, the program explains both Type A and Type B varieties and shows how treatments have evolved over the decades....

They lurk in nursing homes and hospitals-anywhere where people's resistance is down. One, VRE, a usually harmless microbe found in the human bowel and genital tract, is already drug-resistant; the other, MSRA, currently treatable with vancomycin-type antibiotics, is quickly becoming resistant to their effects. Using real-life case studies of patients who are infected, this program studies the effects of the diseases, how they are contracted, and their...

As scientific discoveries continue, will we one day produce a flawless human specimen? We already have breast implants from body tissue and facial surgery using organic materials to make us look younger or correct deficiencies resulting from diseases or accidents. Paraplegic patients learn how to walk assisted by a robot and prosthesis that react like a healthy arm are already available. The dream of human perfection may soon become a reality?

Heart valves fabricated from the body's own cells are durable and are not rejected. Stimulating the natural growth of blood vessels to skirt clogged ones could make elaborate bypass surgery obsolete. As this program shows, these are some of the tools, either in use or under development, that place vascular science at the forefront of medicine. The program also highlights innovations in clot-dissolving drugs, artificial hearts, on-the-spot repairs...

Less bleeding, less infection, shorter hospital stays-robot-assisted surgery offers these and other benefits, and will probably become the standard in time. This program educates viewers about robotic surgery, focusing on two difficult procedures-prostatectomy and heart bypass surgery-that robotic support has vastly improved. Featuring the da Vinci robot, which gives doctors remote surgical capability and ultra-fine dexterity, the program offers the...

This video segment introduces Ryan Ogden who recently had reconstructive knee surgery and is about to become the first Australian to receive an injection of donor stem cells in the knee to prevent osteoarthritis. Injecting stem cells into the legs of horses has proved a resounding success, and now it is Ryan's turn to take part in this revolutionary trial aimed at helping arthritis patients.

Astonishing ways to share scientific data are emerging in the digital age. This program explores the phenomenal growth of supercomputing and its impact on medicine, oceanography, air traffic control, law enforcement, and other fields. Showcasing practical examples of dynamic visualization technology, the video looks at three-dimensional renderings of cities accurate to the square foot, medical imaging capabilities on the cellular level, and instantaneous...

Insights into immune system disorders are unlocking new treatments for rheumatoid arthritis. Many of these innovative approaches are explored in this program, such as experimental drugs that suppress messenger proteins, treatments to regenerate cartilage through the use of stem cells, and the cultivation of chondrocyte cells in the lab. The program looks at detection and treatment of reactive arthritis, minimally invasive surgical techniques, and...

How can we begin to understand the way the brain works? Perhaps in the same way that cities can be understood: by making a map. In this visually stunning TEDTalk, Allan Jones shows the audience how his team is mapping out which genes are turned on in which brain region, and what the implications of this gene expression are. As CEO of the Allen Institute for Brain Science, Jones is leading an ambitious project to build an online, interactive atlas...

A must-see for parents and doctors as well as for medical students, this program comes to grips with the controversial topic of human growth hormone therapy. Five case studies shed light on a variety of related topics, including the role of the pituitary gland and genes in growth, diagnostics such as bone age X-rays and growth hormone provocative testing, treatment modalities and side effects, and applications of growth hormone to cases of renal failure...

As this program illustrates, direct access to the eye coupled with technological wizardry has meant that ophthalmology is one of the most rapidly advancing areas of medicine. Both up-to-the-minute techniques and experimental procedures are profiled, such as photodynamic therapy, which inhibits macular degeneration by eroding deposits called drusen. The program shows how microsurgery, particularly the LASIK method, has revolutionized the field. Also...

In order to save lives, emergency room procedures require teamwork and split-second timing-not unlike what goes on in an airplane cockpit. In this program, medical professionals watch a performance of Charlie Victor Romeo, a play based on a number of actual air disasters, and then implement the lessons from aviation by adopting a more systemic approach to safety. The video shows hospital staff performing dramatic reenactments of medical crises patterned...

The malaria parasite and its human hosts are locked in an evolutionary arms race. The parasite kills more than a million people every year. Humans fight back with gradual genetic adaptation and better drugs. The parasite then adapts and displays drug resistance. In this science bulletin, immunologist Dyann Wirth and her team at the Harvard School of Public Health study the evolutionary adaptations of Senegalese people and their malaria parasites in...
