What are the characteristics of acute appendicitis? The specific analysis is as follows:
First, abdominal pain
The typical acute appendicitis shows abdominal pain in the early stage, and it will metastasize after a few hours, so it is difficult to determine its correct location. Acute appendicitis is usually persistent or paroxysmal dull pain, and sometimes severe appendicitis can lead to perforation, but abdominal pain can alleviate the condition. However, this phenomenon is temporary, and other accompanying symptoms and signs have not improved or will be aggravated.
Second, gastrointestinal symptoms
Acute appendicitis is likely to cause gastrointestinal discomfort, but it is not prominent. However, in the early stage, you will feel nausea and vomiting due to reflex stomach cramps, and the frequency of defecation will increase due to pelvic appendicitis or gangrene and perforation of the appendix.
Third, a fever.
A fever is a low-grade fever without shivering. High fever is mostly acute appendicitis perforation or peritonitis, accompanied by chills and jaundice, and purulent portal phlebitis may occur at any time.
Fourth, tenderness and rebound pain.
Abdominal tenderness means that the peritoneum is stimulated by inflammation, and the tender point of the appendix is located at Maxwell point, that is, the junction of the middle and outer 1/3 of the right anterior superior iliac spine and the umbilical cord. The location of the tender point can also change according to the anatomical point of the appendix, but the most important thing is that there is a fixed tender point in the right lower abdomen. If the patient is obese, the tenderness will be lighter, but it will feel very painful.
Five, abdominal muscle tension
If acute appendicitis suppurates, abdominal muscle tension symptoms will appear, especially when gangrene perforation complicated with peritonitis, the symptoms will be more obvious. However, the abdominal muscles of the elderly or obese patients are weak or even absent, so it is necessary to check and compare the contralateral abdominal muscles at the same time to determine whether there is abdominal muscle tension.
Sixth, the skin feels allergic.
In the early stage of acute appendicitis, that is, the appendix cavity is blocked, you will feel skin allergy, but there is one triangle that does not. Because the appendix changes in different positions, such as gangrene and perforation of the appendix, the skin allergy in this triangle area disappears immediately.
