RÉSUMÉ
Objective To investigate the clinical significance of PiCCO monitoring in critically ill patients' capacity management. Methods Selected 40 cases critically ill patients from January 2012 to January 2014 in our ICU,22 cases were treated with PiCCO monitoring,established the observation group,18 cases were treated with superior vena cava catheterization monitoring,established the control group,the APACHEⅡ score, HR, MAP, CVP,EVLWI GEDVI,me-chanical ventilation time,ICU stay time were compared. Results GEDVI in the observation group at third day after treatment significantly increased than the first day,and the second day(P<0.01﹚. The EVLWI in the observation group at third day after treatment obviously decreased than before treatment, the first day,the second day after treatment re-spectively(P<0.05﹚. The APACHEⅡ score, HR, MAP, CVP in observation group respectively compared with the control group, there was significant difference (P<0.05﹚. The mechanical ventilation time, ICU stay time in the ob-servation group were significantly shorter than that the control group(P<0.05﹚. Conclusion The capacity index applica-tion of PiCCO monitoring in critically ill patients to guide capacity management is superior to CVP monitoring,facili-tates the assessment the treatment and prognosis in critically ill patients.
