Diarrhea |

|
Definition |
|
說(shuō)明 |
|
Diarrhea is not a disease but a symptom. It is commonly used to denote an increase in stool frequency or volume and an increase in the looseness of stool. |
腹瀉不是病，它只是一種癥狀，通常是指排便次數(shù)或量的增加及大便變得更為稀松。 | |
|
Clinical Manifestations |
臨床表現(xiàn) | |
|
Diarrhea may be acute or chronic. Acute diarrhea most commonly results from infection. Bacterial or viral infection of the intestine may result in explosive watery diarrhea, tenesmus (spasmodic contraction of anal sphincter with pain and persistent desire to defecate), and abdominal cramping pain. Perianal skin excoriation may also develop. Acute diarrhea is often self-limiting with symptoms continuing until the irritant or causative agent is excreted. |
腹瀉可以分為急性和慢性。急性腹瀉多數(shù)是由感染引起的。腸道被細(xì)菌或病毒感染，引起暴發(fā)性水瀉、里急后重（肛門(mén)括約肌痙攣性收縮伴疼痛，一直想要排便)及腹部絞痛。還可能出現(xiàn)肛周表皮脫落。急性腹瀉通常是自限性的，在刺激物或病原體清除后癥狀就可消失。 | |
|
Systemic manifestations may include fever, nausea, vomiting, and malaise. Leukocytes, blood, and mucus may be present in the stool, depending on the causative agent. |
全身生癥狀可能包括發(fā)燒、惡心、嘔吐、不適感等。大便可能含白細(xì)胞、血和粘液，這要視引起腹瀉的原因而定。 | |
|
Diarrhea is considered chronic when it persists for at least 2 week or when it subsides and returns more than 2 to 4 weeks after the initial episode. Severe diarrhea may be debilitating and life-threatening. |
慢性腹瀉是指腹瀉時(shí)間至少持續(xù)2周或者在消退后2至4周又再次發(fā)作。嚴(yán)重的腹瀉可以導(dǎo)致人體虛弱甚至威脅性命。 | |
|
A patient may have severe dehydration (water and sodium loss) and electrolyte disturbances. Malabsorption and malnutrition are also sequelae of chronic diarrhea. |
病人可能出現(xiàn)嚴(yán)重脫水（水和鈉丟失)和電解質(zhì)紊亂。慢性腹瀉后遺癥包括吸收不良和營(yíng)養(yǎng)不良。 | |
|
Diagnostic Studies |
診斷檢查 | |
|
Accurate diagnosis and management requires a thorough history, physical examination, and, when indicated, laboratory tests. |
作出準(zhǔn)確診斷需要徹底了解病史、進(jìn)行體格檢查，必要時(shí)進(jìn)行實(shí)驗(yàn)室化驗(yàn)。 | |
|
A history of travel, medication use, diet, previous surgery, interpersonal contacts, and family history should be obtained. |
病史包括：旅游、用藥、飲食、既往手術(shù)、人際接觸及家族史等。 | |
|
Blood tests may be performed to identify anemia, elevated white blood cell (WBC) count, iron and folate deficiencies, liver enzyme increases, and electrolyte disturbances. |
可以進(jìn)行血液檢查以確認(rèn)貧血、白細(xì)胞增多、鐵和葉酸不足、肝酶增加和電解質(zhì)紊亂。 | |
|
Stools may be examined for blood, mucus, WBCs, and parasites. Stool cultures may help in identifying infectious organisms. |
化驗(yàn)大便看有無(wú)血便、粘液、白血球、寄生蟲(chóng)等。 | |
|
In a patient with chronic diarrhea, measurement of stool electrolytes, pH, and osmolality may help to determine whether diarrhea is related to decreased fluid absorption or increased fluid secretion (secretory diarrhea). |
慢性腹瀉病人測(cè)定糞便電解質(zhì)、pH值、溶質(zhì)度，這有助于確定腹瀉是否與液體吸收減少或液體分泌增加（分泌性腹瀉)有關(guān)。 | |
|
Measurement of stool fat and undigested muscle fibers may be indicative of fat and protein malabsorption conditions, including pancreatic insufficiency. Elevated serum levels of GI peptides such as vasoactive intestinal polypeptide (VIP) and gastrin may be present with secretory diarrhea. |
檢查糞便脂肪及未消化肌纖維可以提示脂肪和蛋白吸收不良，包括胰功能不全。胃腸肽血清值升高，如腸血管活性多肽和胃泌素，可以提示患者為分泌性腹瀉。 | |
|
Endoscopy may be used to examine mucosa and to obtain specimens for examination.醫(yī)學(xué)全在線www.med126.com |
內(nèi)鏡檢查可用以檢查粘膜，提取檢查標(biāo)本。 | |
|
Upper and lower barium studies may be helpful in detecting mucosal disease. |
上下鋇檢查有助于發(fā)現(xiàn)粘膜病。 | |
|
Therapeutic Management |
治療措施 | |
|
The treatment of diarrhea is based on the cause and is aimed at replacement of fluid and electrolytes and decreasing the number, volume, and frequency of stools. Oral solutions containing glucose and electrolytes are often sufficient to replace losses due to mild diarrhea. In severe diarrhea, parenteral administration of fluids and electrolytes is warranted. |
根據(jù)病因?qū)Ω篂a進(jìn)行治療，并以補(bǔ)充液體和電解質(zhì)、減少排便數(shù)量、容量和次數(shù)為目的�？诜�葡萄糖和電解質(zhì)類溶液一般足以補(bǔ)充輕度腹瀉所造成的液體丟失。嚴(yán)重的腹瀉，非腸道補(bǔ)液、電解質(zhì)較有保障。 | |
|
Once the cause has been ascertained, antidiarrheal agents may be given to coat and protect mucous membranes, inhibit GI motility, decrease intestinal secretions, and decrease central nervous system (CNS) input to the GI tract. |
一旦查明病因，就可以給服止瀉藥，以保護(hù)粘膜，抑制腸道運(yùn)動(dòng)，減少腸道分泌素，減少中樞神經(jīng)系統(tǒng)對(duì)腸道的信號(hào)傳輸。 | |
|
Antiperistaltic agents are not given to a patient who has infectious diarrheal syndromes because of the potential for prolonging exposure to the infectious agent. Antidiarrheal medications should not be given over a prolonged time. |
感染性腹瀉綜合癥病人不宜服用抗蠕動(dòng)藥物，因?yàn)檫@可能延長(zhǎng)感染源的接觸時(shí)間。止瀉藥不宜長(zhǎng)期服用。 | |
|
Antibiotics are usually not indicated in the treatment of diarrhea because they can cause diarrhea by altering normal bowel flora. |
治療腹瀉通常不需用抗生素，因?yàn)樗鼤?huì)改變腸道正常菌叢，導(dǎo)致腹瀉。 | |
