Acute appendicitis
Acute appendicitis nursing care
The nursing care for acute appendicitis includes preoperative care and postoperative care. Before surgery and on the day of surgery, fasting is required; the patient should not eat anything. At the same time, it is important to soothe the patient's emotions. If the pain is very severe, sedative analgesics can be used. After the surgery, dietary care should be intensified. On the first day after the surgery, a liquid diet should be administered. After bowel gas is passed, a normal diet can be resumed on the third to fourth day. It is important to monitor vital signs and the condition of the surgical incision to prevent infection. The patient can engage in activities out of bed 24 hours after surgery. Elderly patients should be assisted in expectoration to prevent dependent pneumonia.
Acute appendicitis complications
The main complications of acute appendicitis include: First, purulent peritonitis, due to the appendix becoming purulent and leading to perforation, pus flows into the abdominal cavity, causing diffuse peritonitis; Second, abdominal abscess, purulent appendicitis that is not treated surgically forms a capsule around the appendix, encapsulating it, and a lump can be felt on the abdominal surface; Third, internal-external fistula, if the abscess around the appendix is not drained in time, it can break through to the intestinal abdominal wall, forming a fistula.
Anesthesia methods for acute appendicitis
The anesthesia method for acute appendicitis is related to the type of surgical treatment. If laparoscopic appendectomy is chosen, general anesthesia is usually required. If a traditional McBurney point incision is used for appendectomy, spinal anesthesia is primarily chosen. Additionally, after anesthesia, gastrointestinal function will be somewhat restricted. Until there is no gas or bowel movement from the rectum, patients should not eat after surgery. Only when the rectum starts to pass gas, indicating that gastrointestinal function is beginning to recover, can the patient begin to consume soft foods.
Causes of Acute Appendicitis
The causes of acute appendicitis mainly include two types: one is the obstruction of the appendiceal lumen, and the other is infection within the appendiceal lumen. The appendix is a tube that communicates with the cecum. If it is blocked by fecoliths or fecal masses, it can lead to increased pressure inside the appendiceal lumen, damage to the mucosa, and bacterial invasion causing infection, which directly leads to acute inflammation. At the same time, gastrointestinal dysfunction can also cause spasm of appendix muscles and blood vessels, leading to blood supply disturbances. Irregular lifestyle habits, overeating, and engaging in vigorous activities after meals can all trigger acute appendicitis.
The Difference Between Acute and Chronic Appendicitis
The differences between acute appendicitis and chronic appendicitis mainly lie in the onset of the condition, physical signs, and laboratory tests. First, regarding the onset of the condition, acute appendicitis occurs suddenly and can involve abrupt abdominal pain, whereas chronic appendicitis often manifests as fixed tenderness in the lower right abdomen and the symptoms are not particularly typical. In terms of physical signs, acute appendicitis presents with migratory pain in the lower right abdomen, while chronic appendicitis generally does not involve rebound pain. Thirdly, concerning auxiliary examinations, acute appendicitis shows a significant increase in the white blood cell count during an attack, whereas in chronic appendicitis, the white blood cell count may appear normal.
Symptoms of acute appendicitis
The typical symptoms of acute appendicitis include abdominal pain that starts around the upper abdomen or navel area, then localizes to the lower right abdomen. There are also manifestations of gastrointestinal spasms such as nausea and vomiting. Due to inflammation entering the bloodstream, there can be a systemic infection, often accompanied by fever, generally not exceeding 38 degrees Celsius. If there is an appendix perforation and peritonitis, the temperature can exceed 38 degrees. After the appendix becomes suppurative, symptoms can include abdominal muscle rigidity, dental pain, and rebound tenderness.
Precursors of acute appendicitis
Acute appendicitis is acute inflammation of the appendix lumen, and currently, there are no particularly typical precursors, but the causes of acute appendicitis should be noted, which are related to obstruction and infection of the appendix cavity. If the appendix lumen is compressed for a long time, the accumulation of secretions can cause blood supply disorders in the distal appendix wall, directly causing damage to the appendix mucosa, and inducing infection that leads to appendicitis. Additionally, gastrointestinal dysfunctions such as diarrhea and constipation can also cause spasms of the appendix muscles and vessels, leading to blood supply disorders and mucosal damage, thereby causing acute appendicitis.
How to medicate for acute appendicitis
Acute appendicitis is commonly treated surgically in clinical settings. Medication for acute appendicitis should be used with caution according to indications; if the appendix is not purulent, it is appropriate to use anti-inflammatory drugs to control the infection and choose sensitive antibiotics, such as quinolones. If the appendix becomes purulent or perforates, timely surgical treatment should be administered to prevent further exacerbation of appendicitis. Before and after the surgery, it is important to monitor whether the patient's symptoms and signs have significantly worsened. (Medications should be taken under the guidance of a physician and based on actual conditions)
The cause of acute appendicitis
The etiology of acute appendicitis is directly related to obstruction and infection of the appendiceal lumen. The appendix, a narrow and elongated tube connected to the cecum, can develop increased luminal pressure due to obstruction, leading to disturbances in the blood supply to the appendiceal wall. This can easily cause damage to the mucosa and subsequent infection. Infection of the appendiceal lumen can directly cause acute appendicitis. Additionally, gastrointestinal dysfunction can also cause muscle and vascular spasms in the appendix leading to blood supply disturbances and the invasion of bacteria, resulting in acute inflammation. For acute appendicitis, surgical treatment should be administered immediately upon diagnosis.
Causes of Acute Appendicitis
The main causes of acute appendicitis are obstruction of the appendiceal lumen and concurrent infection. The appendiceal lumen is a narrow tube that communicates with the cecum at one end. Obstruction, such as a fecalith, can lead to increased pressure inside the lumen, disturbances in blood flow, damage to the mucosa, and secondary infection. It can also be caused by direct bacterial infection within the appendiceal lumen, leading to acute inflammation. Additionally, repeated diarrhea or constipation and other gastrointestinal dysfunctions can also cause circulation disturbances in the appendix, leading to bacterial invasion and acute inflammation.
