Adventures in qualityland.Several years ago, my aortic valve aortic valve n. The valve between the left ventricle of the heart and the ascending aorta, consisting of three semilunar cusps. Aortic valve had to be replaced, and my wife insisted that I find a doctor near our retirement home. I searched around and finally settled on a nationally known clinic that had just opened an outpost not too far from our town. Let's call it the Mustard Clinic. Recently, the cardiologist at Mustard decided that I should have a transesophageal echo of my artificial valve, and so, after a few questions, I agreed to have the procedure scheduled. A few months before, while having a routine echocardiogram ech·o·car·di·o·gram n. A visual record produced by echocardiography. Echocardiogram A non-invasive ultrasound test that shows an image of the inside of the heart. , the technician asked why I was not having a transesophageal echo, and went on to describe the new tube they were using. "No bigger than an N-G tube", she said, and that sounded acceptable to me. I knew that I would need SBE SBE - Microsoft Office Small Business Edition prophylaxis, but nothing else was mentioned about preparation except that I should be fasting. As a matter of fact, I went through the scheduling and instruction phase at Mustard twice, because my first appointment had to be canceled. The day before the appointment, the clinic called to ask if I could come early, as they "had to squeeze in" another case that morning. I agreed, arrived on time, and was called the usual 30 minutes after I arrived. The IV gentamicin gentamicin /gen·ta·mi·cin/ (jen?tah-mi´sin) an aminoglycoside antibiotic complex isolated from bacteria of the genus Micromonospora, and ampicillin ampicillin (ăm'pĭsĭl`ĭn), a penicillin-type antibiotic that is effective against both gram-negative microorganisms and gram-positive microorganisms such as Escherichia coli. was started but was run in half the usual time, because "we are behind schedule." When the proceduralist came in to introduce himself and his resident, I told him that I had a rather hyperactive gag reflex gag reflex n. Retching or gagging caused by the contact of a foreign body with the mucous membrane of the throat. Gag reflex . He said that was okay, because they would use a small amount of IV sedation Sedation Definition Sedation is the act of calming by administration of a sedative.

My wife happened to be 2,000 miles away visiting her mother. I said that I could not wait for her, and, anyway, I had a car parked outside. He said, "That's okay. Just hang around for a few hours, and you should be okay." I told him, "Sorry, but |should be' is not good enough." I did not want my life endangered when I drove home. So he gave me two squirts of topical anesthetic and started the procedure. You can image my surprise when the "N-G tube" turned out to be a standard diameter gastroscope gastroscope /gas·tro·scope/ (gas´tro-skop) an endoscope for inspecting the interior of the stomach.gastroscop´ic gas·tro·scope n. An endoscope for examining the inner surface of the stomach. , which looked to me like the diameter of the Holland Tunnel. Upon insertion, I gagged uncontrollably. Two more squirts of topical, and, with one hand in my mouth and the other guiding the scope, he started again. I was still gagging, but I was told to "take a few deep breaths." Now, I know that line. I was taught it in the bad old days of medicine, when patients had to endure more than necessary pain or discomfort. It's like "I'm sorry you feel that way" when used by a physician manager. Of course, the proceduralist had not read the entire chart and was unaware of the fact that I had some urologic surgery at Mustard five years ago that left me with a little stress incontinence stress incontinence n. A sudden, involuntary release of urine caused by muscular strain accompanying laughing, sneezing, coughing, or exercise, seen primarily in older women with weakened pelvic musculature. . So the more he pushed the scope down, the more I gagged and the more wet I became. Finally, I freed a hand and waved him off. He was angry to have a perfectly fine procedure stopped, and I was lying there feeling raped. My pants were soaked with urine, so I had to walk out of the clinic with a dark stain covering my crotch crotch n. The angle or region of the angle formed by the junction of two parts or members, such as two branches, limbs, or legs. . No one offered me a pair of scrub pants to wear home instead of my urine-soaked chinos, nor, for that matter, had they thought to offer the use of scrub pants for the procedure. The physician's note, of course, just reflected that I had stopped the procedure, not that I had received inadequate instructions or anesthesia, or that my kidneys may have lost a nephron nephron: see urinary system. nephron Functional unit of the kidney that removes waste and excess substances from the blood to produce urine. Each of the million or so nephrons in each kidney is a tubule 1.2–2.2 in. (30–55 mm) long. or two from a rapid gentamicin infusion. The following day, I filed an incident report with the patient representative and, in a letter, informed the clinic that I wasn't about to have my insurance company pay for that kind of treatment. The next day, my cardiologist called to say he was sorry I had trouble with the procedure and that my pro-time was way off. I had better increase my Coumadin. But that's another story. Another Story I was surprised to hear that my pro-time had fallen to 14.5 seconds. The measurement had been 22 seconds six weeks ago, but, as I thought about it, I just assumed that Coumadin is a very unpredictable drug. Of course, I had been taking Coumadin since installation of the replacement aortic valve eight years ago and had, for the most part, managed my own anticoagulation. About two months before, the cardiologist at Mustard Clinic had decided he wanted to manage the coagulants and began to adjust the dose. We had started with a pro-time of 22 seconds, and he wanted it about 18 seconds. I had been using the new normalization In relational database management, a process that breaks down data into record groups for efficient processing. There are six stages. By the third stage (third normal form), data are identified only by the key field in their record. ratio, which, for you noninternists, adjusts the results to compensate for variables in the substrates used in the prothrombin prothrombin Carbohydrate-protein compound in plasma essential to coagulation. In response to bleeding, a complex series of clotting-factor interactions leads to its conversion by thromboplastin to thrombin, which transforms fibrinogen in plasma into fibrin. determination. I was shooting to 3.0, and I thought that the original 22 seconds was probably above the 3.0 level I was using. Anyway, the dose was dropped, and, two weeks later, the new pro-time was reported as 22 seconds. I asked the nurse who called with the results and the doctor's new dosage schedule what the ratio was, and she said emphatically, "We don't use those here." I hadn't heard that tone since I was an intem dealing with a very senior nurse. I guessed they had standardized their thromboplastin thromboplastin: see blood clotting. , or whatever the substrate was. (Like most of you, I never could remember the clotting mechanism.) I thought the new dose was too low and said that, when using that dose in the past, I had become under-coagulated. The nurse assured me that the doctor knew what he was doing, so I went along. The truth of the matter became clear when a friend of mine in the surgical division gave me my lab results. Even if "they didn't use those ratios," the lab reported them. The second 22-second pro-time was reported with a normalization ratio that had fallen significantly from the first 22-second pro-time. I was actually borderline under-coagulated when the dose was reduced the second time. Even if the new ratios weren't the final determinant of dose, at least they should have been used as a warning that my pro-time was lower than it looked. The second reduction in dose should have been more cautious, or some one should have listened to the patient. Now that I had been un-anticoagulated, I decided that I could do a better job and took over management of my anticoagulants Anticoagulants Drugs that suppress, delay, or prevent blood clots. Anticoagulants are used to treat embolisms. Mentioned in: Embolism, Heart Valve Replacement , along with my other duties. |
