Application of PiCCO in COPD patients with sepsis shock / 中国基层医药

ABSTRACT

Objective To evaluate the clinical effects of PiCCO in the treatment of COPD patients with sepsis shock.Methods 43 COPD patients with sepsis shock were randomly divided into two groups.The control group (n =23) were guided fluid resuscitation according to CVP.The study group (n =20) were placed PiCCO,and according to the PiCCO for fluid resuscitation.The average amount of fluid resuscitation,the amount of norepinephrine and the blood lactate level in 24 hours were observed.The average duration of mechanical ventilation and ICU mortality were also observed.Results After 24 hours,the average amount of fluid resuscitation was (3 986.2 ± 542.1) ml of control group and (4 927.9 ± 761.8)ml of study group,the difference between the two groups was statistically significant (t =-4.71,P ＜ 0.05).The average norepinephrine dosage was (0.38 ± 0.21) μg · min-1 · kg-1 of control group and (0.14 ±0.08)μg · min-1 · kg-1 of study group,the difference between the two groups was statistically significant (t =2.45,P ＜ 0.05).The blood lactate level was (4.79 ± 1.95) mmol/L of control group and (3.44 ±1.45) mmol/L of study group,the difference between the two groups was statistically significant(t =2.59,P ＜ 0.05).Five patients died in control group(mortality 21.7％),and three patients died in study group(mortality 15.0％).Mortality between the two groups was not statistically different (x2 =0,03,P ＞ 0.05).The duration of mechanical ventilation in the control group was (101.22 ± 44.77) h,that in the study group was (74.71 ± 20.25) h,the difference between the two groups was statistically significant (t =2.234,P ＜ 0.05).Conclusion Long-term COPD patients maybe have right ventricular dysfunction,and CVP is difficult to truly reflect the volume status of patients,PiCCO can make up for deficiencies in CVP.PiCCO used to guide these patients with fluid resuscitation,which could guide fluid management of patients,reduce the amount of vasoactive drugs,improve tissue hypoxia,and could reduce the duration of mechanical ventilation.
