Giới thiệu Một số chủ đề khó và dễ nhầm lẫn nhất trong y khoa là các rối loạn về dịch, điện giải và toan kiềm. Mặc dù những rối loạn này thường gặp trong lâm sàng, nhưng sinh lý bệnh của chúng còn nhiều vấn đề chưa được hiểu rõ. Một lý do khiến những rối loạn này không được các sinh viên và bác sĩ nội trú hiểu rõ là những rối loạn điện giải không được giảng dạy như một khóa học dính liền duy nhất trong trường y khoa, hay đúng hơn là chủ đề này được chia thành nhiều môn học và trong nhiều năm khác nhau. Ví dụ, rối loạn toan kiềm được giới thiệu trong suốt môn sinh lý hô hấp và thận, trong khi thực hành chẩn đoán lại được dười đến những năm học lâm sàng; tương tự, các rối loạn điện giải một phần được nói đến trong sinh lý thận học, còn thực hành thì bị trì hoãn cho đến học phần nội khoa ở năm 3 của trường y. Chính chúng tôi đã lội ngược dòng khi quyết định viết một cuốn sách toàn diện về chủ đề này. Mục tiêu của chúng tôi là cung cấp cho sinh viên y khoa một mô hình khái niệm về cách hoạt động sinh lý của natri, kali và H+ trong cơ thể và hỗ trợ kiến thức khái niệm đó bằng các phương pháp tiếp cận lâm sàng hợp lý đối với các rối loạn về dư thừa và thiếu hụt của chúng. Để đạt được mục tiêu này, chúng tôi trình bày thông tin thành năm phần trên mỗi trang. Tiêu đề màu xám ở đầu mỗi trang hướng người đọc đến dàn ý cơ bản của chương và trang hiện tại phù hợp với dàn ý đó. Sau đó, khái niệm chính của trang được tóm tắt trong một câu duy nhất. Dưới tiêu đề là một hình ảnh minh họa khái niệm. Bên dưới hình ảnh là một số văn bản, hiếm khi dài hơn ba đoạn, mô tả ngắn gọn khái niệm. Cuối cùng, ở cuối mỗi trang là một vài câu hỏi được thiết kế để củng cố các điểm chính cũng như xác nhận rằng người đọc đang tham gia vào văn bản chứ không chỉ đơn thuần là lật các trang. Ngoài ra, nhiều trang có bình luận được đánh dấu bằng các biểu tượng. Có ba biểu tượng được sử dụng trong cuốn sách: Liên kết đánh dấu thông tin được đề cập trong một phần khác của cuốn sách. Số chương và số trang được liệt kê để tham khảo nhanh. Dấu chấm than nêu bật những điểm tinh tế và / hoặc quan trọng cần được nhấn mạnh. Đặc biệt chú ý đến những điểm này vì chúng thường là công cụ để hiểu tài liệu.Enjoy. Sarah Faubel and Joel Topf Bóng đèn chỉ ra những điểm thú vị có liên quan, nhưng không quan trọng, đối với khái niệm đang được thảo luận. Chúng tôi cảm thấy rằng bốn năm nỗ lực đổ vào cuốn sách này đã tạo ra một cuốn sách về dịch, điện giải và axit-bazơ tốt nhất từng được viết cho sinh viên y khoa và bác sĩ nội trú. Chúng tôi hy vọng bạn đồng ý.

Authors You might be asking yourself “What kind of medical residents have the time or energy to write a book?” While the first answer that comes to mind may be “insane, hypomanic individuals,” the actual answer is quite a bit more mundane Sarah and Joel are veterans of the “war” known as medical school who think that the whole process could be a bit less painful if there were well-conceived learning materials Both authors continually evaluate their surroundings with an eye toward making things easier and more intuitive Unfortunately, the medical world is filled with such opportunities Sarah and Joel began writing this book after graduation from the Wayne State University School of Medicine in 1995 They worked on it through a transitional internship at the Detroit Medical Center and during their respective residencies: Sarah in internal medicine at the University of Colorado and Joel in combined medicine/pediatrics at Indiana University Both authors are planning to fellowships in nephrology Joel and Sarah, after careful review of their experience, would offer without reservation that it is not a good idea write a book during residency About Alert and Oriented Publishing As Joel and Sarah’s first book, The Microbiology Companion, was taking shape, they showed drafts to friends and family One friend, Joel Smith, avidly encouraged them to sell the book nationwide One discussion turned to many, and the authors agreed to let Smith sell the book at the University of Michigan where he was beginning a joint J.D./M.B.A program The book sold out four times in three weeks After more discussion, what now seems a natural partnership began to form The three incorporated Alert and Oriented Publishing in the fall of 1993 Joel Smith is currently a venture-capital lawyer working in the twin brave new worlds of bioand info- technology In addition to the Fluid, Electrolyte and Acid-Base Companion, Alert and Oriented Publishing also publishes: The Microbiology Companion, Topf and Faubel The Pharmacology Companion, Gallia, Hann and Hewson Biochemistry on a Board (B.O.B), Carroll vi S Faubel and J Topf Acknowledgments In our modest experience, there are two critical time periods in the creation of a book: the beginning and the end We would like to thank the individuals who helped make those critical moments successful The Beginning The Detroit Medical Center and Dr Ernest Yoder were instrumental in getting this book started by providing the critical resource, time, during our transitional internship in 1995-96 Dr Yoder, thanks for trusting us The End The final finishing touches to the book were completed during a ten day retreat to Breckenridge, Colorado called “FinishFest.” The FinishFest team was essential in transforming a prototype version into a final cohesive book Thank you for helping us achieve the dream Warren Capell, MD Joel S Smith Catherine Spratt Stefanie Schiff The following individuals were essential in getting the book to its current form by reading early prototypes and providing critical feedback: Rajiv Agarwal, MD Mary Ciccarelli, MD Jeffery Gatz, MD Ravi Gopal, MD Samir Gupta, MD Hasmeena Kathuria, MD Sophia Kim, MD

Ths.Bs Phạm Hoàng Thiên S Faubel and J Topf W ater, tha t’s w hat I’m getting at, water! Mandrake, water is the source of all life Seven-tenths of this earth’s surface is water Why, you realize, that 60% of you is water? And as human beings, you and I need fresh pure water to replenish our precious bodily fluids General Jack Ripper Doctor Strangelove ix PRN Personal reference nephron, use as needed Glomerulus Distal convoluted tubule 290 mmol/L 100 mmol/L 285 mmol/L Proximal tubule 510 mmol/L Collecting tubule 735 mmol/L • principle cell • intercalated cell 290 mmol/L Loop of Henle 960 mmol/L Medullary interstitium 1185 mmol/L 1400 mmol/L (concentration gradient) urine concentration • 30-50 mmol/L without ADH • 900-1400 mmol/L with ADH The Nephron The functional unit of the kidney is the nephron; therefore, all of the fundamental functions of the kidney can be understood by looking at a single nephron There are over one million nephrons in each kidney Each nephron is composed of six basic components Loop of Henle The loop of Henle is the engine which drives the dilution and concentration of urine The loop contains NaK-2 Cl transporters in the ascending limb which pump solutes (Na+, K+ and Cl–) from the tubule into the medullary interstitium Fluid exiting the loop of Henle has an osmolality of 50 to 100 mmol/L Glomerulus The glomerulus is the first part of the nephron and creates tubular fluid by filtering the blood Blood from the renal arteries fans through the arterial tree to the afferent arterioles From the afferent arterioles blood enters the glomerular capillaries where the blood is divided into two componants: tubular fluid (which eventually becomes urine) and unfilterable large solutes (which are returned to the blood) The tubular fluid is created by filtering the blood and allowing water, electrolytes and small nonelectrolytes (e.g., urea, glucose) to pass through the glomerular membrane while protein and the cellular components of blood are prevented from passing this membrane ++ ++ Ca and Mg are resorbed in the loop of Henle Proximal tubule The proximal tubule is responsible for the large-scale resorption of filtered water and solutes It reduces the volume of the filtrate by Fluid is resorbed in an isotonic manner; that is, the osmolality of fluid entering the proximal tubule has the same osmolality as fluid leaving the proximal tubule Angiotensin II increases the resorption of sodium and water in the proximal tubule Specific transporters recover vital solutes that are filtered by the glomerulus Examples of solutes recovered by the proximal tubule include amino acids, glucose and bicarbonate Medullary interstitium The medullary interstitium is a salty brine created by the loop of Henle The medullary interstitium is essential to the formation of concentrated urine Distal (convoluted) tubule The distal tubule resorbs sodium and dilutes the urine in a fashion similar to the loop of Henle The distal tubule is considered part of the distal nephron Collecting tubule The collecting tubule is responsible for maintaining acid-base and potassium balance in addition to regulating the concentration of urine The collecting tubule is part of the distal nephron There are two primary types of cells in the collecting tubule: principle cells (secrete potassium, resorb sodium) and intercalated cells (secrete hydrogen) The resorption of sodium and the secretion of both potassium and hydrogen is enhanced by the hormone aldosterone The collecting tubule also regulates the concentration of urine under the influence of ADH With ADH, the collecting tubules become permeable to water and produce concentrated urine The absence of ADH causes the dilute tubular fluid from the distal convoluted tubule to be excreted unchanged baroreceptor –
