全靜脈營養輸注院內感染之影響因素探討

The Prospective Study for the Effect Factors of Nosocomial Infection with Total Parenteral Nutrition Infusate

摘要


The aims of this study were to display the incidences of infections and risk factors of total parenteral nutrition (TPN) via central venous catheter. The objects included all the patients aged 15 and Over who had TPN infusion in a medical center. In the prospective study, there were 1,134 patients having accept TPN infusate with in three years. The crude infection rate was 11.5%, including 9.3% bloodstream infection, 2.2% inject site infection, and 1.1% catheter-related blood-stream infection. The incidence density of infection was 5.4 episodes. The mean age of all patients who accepted TPN infusate were 64.4±16.1. The age of infection and no infection had significant statistic difference (p<0.05). Further stratified analysis showed the risk that 76 and older infection was 2.39 times (95% CI 1.14-5.14, p<0.05) higher than 45 and younger. The infection of the TPN infusate of 21-30 days and 31 days above were higher than 1-lOdays by 4.96 times and 8.07 times (p<0.00 1) respectively. All potential risk factors by logistic regression analysis founded the TPN infusate over 21 days for these over 76 years to have significant statistics difference (p<O.05) too. Conclusion: over 76 year olds and over 21-day TPN infusate are risky factors of nosocomial infection.
