Technical Editing Example

Technical Editing Example One of the main focuses of my higher education has been technical writing. Both during my time as a Professional Writing major at Michigan State University and as an English major at Northern Illinois University, I honed my ability to tailor my words to suit different audiences.

Most often, I use this skill to translate complex ideas for an uninformed audience.

This project was an assignment I was given in a grad-level Technical Editing course, which created a problem that an editor could solve. It challenged me to take text on open-heart surgery written by a medical professional and use both written language and visual aids to project the same information, while making it easier to absorb for my intended audience: concerned patients with no formal medical education.

The text given to me in the assignment was disorganized, repetitive, and unclear. By using the skills I'd learned in class up to that point, I was able to reduce it in length, boost its clarity, and make it easier to skim for those readers looking for a particular piece of information (as not all of my intended audience would necessarily be interested in reading the entirety of the text). I think the results of this project showcase my ability to understand complex text, to perform research to supplement existing material, and to communicate information efficiently.

WHAT IS “OPEN HEART SURGERY”?

By Donald L. Bricker, M.D. This question is often asked perhaps more of patients who have experienced “open heart surgery” than of physicians. It is even posed in an argumentative fashion in some circumstances, and the author has been called more than once to arbitrate as to whether a given surgical procedure was or was not really “open heart surgery.” The confusion surrounding the use of the term is quite understandable, since the term “open heart surgery” was coined over two decades ago and is very vague today when applied to the large area of cardiac surgery which it may be used to describe.

Perhaps the term was coined originally because the heart surgeon was concerned with methodology which would allow him to correct congenital heart defects which actually entailed opening the cardiac chambers for repair. Yet, this nosological consideration for procedures performed within cardiac chambers overlooked the true area of common ground which set cardiac surgery apart in terms of magnitude and risk. This area of common ground was simply the need to relieve the heart of his physiological burden while operating on it. In other words, heart operations of great magnitude are best grouped together by the necessity of providing an external mechanical support system to substitute for the function of the heart and lungs in pumping and oxygenating blood. Any heart operation, therefore, which requires that the heart either be sopped for the procedure, or undergo such manipulation that it cannot perform its designated function, would fit this classification. The external mechanical support system referred to is, of course, the “heart-lung machine.” What is today implied by the term “open heart surgery” in common medical parlance, then, is any cardiac operation requiring the use of the “heart-lung machine.”

What does the “heart-lung machine” do? First, let us exchange that term for “cardiopulmonary bypass” to aid in our understanding. Basically, cardiopulmonary bypass removes the heart and lungs as a unit from the circulatory system and temporarily bypasses them while performing their function. To accomplish this, blood is diverted from the heart by tapping into the great veins delivering blood from the upper and lower extremities.

This blood flows by gravity into an oxygenating device which performs the lungs’ function of adding oxygen and dissipating carbon dioxide. This blood is then pumped back into the circulatory system through a convenient artery, usually the aorta, the great artery that comes immediately from the heart. It can be seen then, that with this system functioning, appropriately placed surgical clamps on the venous and arterial sides of the heart and lungs would totally isolate them. This allows the surgeon to stop the heart if he wishes and perform his operation in a precise and unhurried fashion. Of course, the cardiopulmonary bypass unit pump-oxygenator, or if you insist, “heart-lung machine”, cannot do this job indefinitely, but sufficient time is safely at hand with today’s equipment that the surgeon need not hold the concern he once did for the time factor. Improvement in this equipment has, more than any other factor, led to the successes we routinely enjoy today. One question frequently asked is about the blood supply to the heart and lungs themselves during this period of “bypass.” Their blood supply is markedly reduced since they are removed from the circulatory system, but since they are at rest, oxygen requirements are minimal, and for the duration of most procedures no problems are posed.

In conclusion, “open heart surgery” has come to be a less than literal term and in common usage implies a cardiac surgical procedure requiring use of cardiopulmonary bypass. It is this factor which sets the operation apart from other operations on the heart. If your operative procedure was or is to be done under cardiopulmonary bypass, rest assured you have undergone or will undergo “open heart surgery.”

Open Heart Surgery: Frequently Asked Questions What is open heart surgery?

Open heart surgery refers to any surgical procedure that requires the heart to be stopped or otherwise tampered with so that it cannot perform its usual function. During the surgery, the patient is supported by a cardiopulmonary bypass unit pump-oxygenator (commonly referred to as a heart-lung machine), a device designed to replicate the purpose of the heart and lungs. Open heart surgery does not necessarily involve opening the heart itself.

What does a heart-lung machine do?

A heart-lung machine works by temporarily "bypassing" the heart and lungs. Blood is diverted away from the heart by drainage tubes, where a machine adds oxygen to it artificially, much in the same way that the lungs normally would. This oxygen-rich blood is then pumped back into the body, effectively removing the heart and lungs from the circulatory system entirely. This necessary practice enables a surgeon to work on or near the heart and lungs without worrying about interrupting their vital function.

What are the risks of open heart surgery?

In recent years, many improvements have been made in the equipment this procedure requires, leading to a higher rate of successful surgeries than ever before. Although the heart and lungs are mostly isolated from the normal flow of blood, their oxygen requirements are minimal since they are at rest. It is not a risk-free procedure, as the heart and lungs are delicate organs, and the heart-lung machine was not meant to be used for long periods. In almost all cases, though, cardiopulmonary bypass gives the surgeon more than enough time to complete the required surgery at a comfortable pace.
