What antibiotics for gastroenteritis?

Gastroenteritis is a very common condition in daily life, which can seriously affect people's normal life and work, and the physical damage to patients is very large, so it is especially important to find effective therapeutic drugs.

Patients need to follow the doctor's treatment recommendations according to their physical condition and then choose the appropriate antibiotics for treatment.

What antibiotics for gastroenteritis?

1. What kind of gastroenteritis is suitable for antibiotics?

Gastroenteritis can be broadly classified into infectious and non-infectious gastroenteritis. Infectious gastroenteritis can be classified into bacterial, viral, fungal, and parasitic gastroenteritis depending on the pathogenic microorganism of the infection. Non-infectious gastroenteritis, a large autoimmune disease, and a small number of drugs, caused by chemical corrosion, physical damage and other gastroenteritis.

With so many gastroenteritis, only bacterial and a few parasitic gastroenteritis are effective in taking antibiotics, and not all bacterial gastroenteritis requires antibiotics; when using antibiotics, depending on the bacteria being infected, the type of use And the dose is not the same. As people pay more attention to food hygiene, parasitic diseases have become less and less, and most of the gastroenteritis that needs antibiotic treatment is caused by bacterial infection.


2. What is the performance of bacterial gastroenteritis?

Bacterial gastroenteritis is generally more acute, mostly in the summer and autumn, which occurs mostly due to improper diet, overeating; or eating cold, rot, turbid and unclean food. There are characteristics of fulminant epidemics, patients with nausea and vomiting first, followed by diarrhea, 3 to 5 times a day, or even dozens of times, the stool is watery, dark yellow or green, stench, can be accompanied There are abdominal cramps, fever, body aches and other symptoms. Regular stool examination and stool culture, blood white blood cell count can be normal or abnormal, patients with nausea and vomiting are called acute gastritis; abdominal pain and diarrhea are often called acute gastroenteritis; clinically often nausea, vomiting, abdominal pain And diarrhea at the same time, it is also known as acute gastroenteritis.

3. How should acute gastroenteritis be treated?

(1) To prevent dehydration, moderate to severe patients may lose a large amount of fluid in the gastrointestinal tract due to severe vomiting and diarrhea, and water and electrolyte balance disorders such as isotonic or hypertonic dehydration, metabolic acidosis and low Potassiumemia, and symptoms of systemic poisoning, so should properly add water and electrolytes, pay attention to drink plenty of salt water to prevent hyponatremia. Seek medical attention if symptoms are severe.

(2) When vomiting is serious, you should go to a nearby hospital for treatment. You can use antiemetics such as metoclopramide to prevent acute vomiting and acute gastric mucosal lesions.

(3) Atropine pain can be temporarily applied when abdominal pain is severe and unbearable, but it will inhibit bowel movements, increase the absorption of toxins and the discharge of pathogenic bacteria, so it should be avoided in the tolerance range.

(4) Use antidiarrheal drugs with caution. When diarrhea discharges a lot of water, it also excretes many pathogenic bacteria and their toxins. Blind diarrhea will delay the removal of pathogenic bacteria in the body. It is safer to adsorb substances. Antidiarrheal drugs such as montmorillonite powder can absorb pathogenic bacteria and toxins in the intestines and alleviate the symptoms of diarrhea.

(5) Appropriate use of probiotics, the underlying mechanism of infectious gastroenteritis is the invasion of foreign bacteria or the balance of the original flora in the intestine is broken, and the rational application of probiotics such as live Bifidobacterium preparations, Bacillus subtilis live Bacteria, etc., can regulate intestinal micro-ecology and promote the recovery of intestinal balance.

(6) Reasonable application of antibiotics, patients with mild symptoms do not necessarily need medication. After timely supplementation of water and electrolytes, the symptoms will gradually disappear as the body's immune system responds. However, when severe vomiting, diarrhea, dehydration symptoms and signs appear, abdominal pain is severe, high fever should not be used when antibiotics should be treated in time, first of all should use spectral antibiotics such as cephalosporins, quinolone antibiotics, conditional can be used for fecal culture After clearing the pathogenic bacteria, the corresponding antibiotics are used for treatment.
