A bottle is called an intravenous infusion. For patients with appendicitis, intravenous fluids usually improve the condition in about 5 to 7 days, but the time varies for each person for various reasons. Appendicitis is divided into acute appendicitis and chronic appendicitis. Acute appendicitis is caused by blockage of the appendiceal lumen, bacterial invasion, etc. Chronic appendicitis is mostly caused by the transformation of acute appendicitis. Generally appendicitis, in the intravenous infusion after 5-7 days will be basically better, but each person’s condition is different, different physique, the specific recovery time is also different. However, some patients with acute appendicitis may need surgery to remove the appendix if the condition cannot be controlled by intravenous fluids, and the appendix is now removed using minimally invasive laparoscopic techniques. If there is no obvious infection after surgery, the patient is usually treated with intravenous anti-infection therapy for 3 days, and commonly used drugs include ceftriaxone sodium, levofloxacin and other antibiotics. Patients with appendicitis should go to the hospital in time for early treatment.
