The result? 2 2 1 18 1 infection rate of patients with liver cirrhosis1kloc-0/case infection. The infection rate was 55.8%, and the hospital infection rate was 27.65438 0%. ? 2.2 The infection site was 10 1 case, and the infection frequency was 133 cases. Among them, 3 people were infected in 4 cases, 2 people were partially infected in 24 cases, and the remaining 73 people were partially infected 1 case. According to the frequency of infection sites, there were 59 cases of primary peritonitis and 5 cases of intestinal infection/kloc-0. 12 cases of upper respiratory tract infection, 9 cases of bacteremia and 8 cases of pulmonary infection and pleurisy. Biliary tract infection, urinary tract infection and oral infection were 5 times each, skin and soft tissue infection was 4 times and septic shock was 3 times. ? 2.3 The incidence of infection-related factors causing infection and liver function is 2.3. 1 children-the first 10 1 infected cases. Patients A, B and C were 1 case, 4 1 case and 49 cases respectively. Among 80 cases of non-infected group, there were 26 cases of A, 39 cases of B and 5 cases of C respectively. The infection rate of Child-C in patients with liver cirrhosis was significantly higher than that in patients without infection. The significant difference between the two groups (x2=22.03, 0.0 1) is shown in table 1. ? In the Child-grade comparison group of liver function (X2), the total number of hepatitis B and C infection groups was 1 1 (20. 6) 41(44.6) 49 (35.7)10/noninfected group, 26 (16.4) 39 (35.4)15 (28.3) 8. When patients with liver cirrhosis are hospitalized, "the chance of infection in January is obviously higher than that in January" (P < 0.01). The relationship between hospitalization time and hospital infection Number of hospital infection cases "1 month 510.2% hospitalization 326.6%"1month 3 1 63.2 2.3.3 Nosocomial infection and10.3 invasive cases. 14 cases underwent abdominal puncture and 4 cases underwent thoracic puncture. ? Supplement: 2.4 The bacteria that have detected Escherichia coli in pathogen culture are: (ascites); Tongluo (ascites); Klebsiella's smelly nose (blood, sputum, bedsore pus), fungi prima Sisha (blood jugular vein intubation), grape skin fungus (sputum), Candida albicans (sputum, fecal throat), Rumsfeld Siddig (sputum). Staphylococcus ear (urine). ? 2.5 Twenty-nine patients died of infection, and the mortality rate was 2 cases without infection in 2002. The mortality rate is 2.5%. On the basis of pathogen detection, the other 72 cases were treated with antibiotics, protective and diuretic therapy. Under the benefits of keeping clean mouth and skin care, infection control has been improved, and the average hospitalization time after discharge is 25.9 days. The other 78 cases without infection were discharged after treatment and nursing, and the average hospitalization time was 65438 06.5 days. The mortality rate of patients with liver cirrhosis infection was significantly higher than that of patients without infection. (X2=2 1.6 0.0 1) Table 3?
