ABSTRACT
Objective: To investigate the efficacies of pulsed continuous cardiac output (PICCO) and central venous pressure (CVP) monitoring in the treatment of the patients with sepsis shock complicated with cardiac insufficiency, and to clarify the clinical significance of PICCO and CVP monitoring. Methods: A total of 137 cases of septic shock combined with cardiac insufficiency patients were randomly divided into CVP group (n= 68) and PICCO group (n= 69). The patients in CVP group were treated with CVP monitoring to guide therapy, and the patients in PICCO group were treated with PICCO monitoring to guide therapy. The levels of lactic acid and B brain natriuretic peptide (BNP), central venous oxygen saturation (ScvO2), heart rate (HR), mean arterial pressure (MAP) and CVP of the patients in two groups were detected before treatment and 6, 24, 48 h after treatment, respectively; the hemodynamic parameters of the patients of PICCO group were recorded; the vasoactive drug use time, the ICU hospitalization time, the incidence rates of multiple organ dysfunction syndrome (MODS), the mechanical ventilation time and the 28 d-mortality rates of the patients were recorded. Results: Compared with CVP group, the levels lactic acid and BNP and HR of the patients in PICCO group at 6, 24, and 48 h after treatment were significantly decreased (P0. 05). There were no significant differences in the incidence rates of MODS and 28 d-mortality rates between two groups (P>0. 05); however the use time of vasoactive drugs, the ICU hospitalization time and the mechanical ventilation time of the patients in PICCO group were significantly shorter than those in CVP group (P< 0. 05). Conclusion; PICCO monitoring guides the treatment of septic shock complicated with cardiac insufficiency better than CVP monitoring, and has positive clinical significance.
ABSTRACT
Objective To evaluate the effect of global end diastolic volume index (GEDVI) on fluid resuscitation in elderly patients with septic shock. Methods A prospective randomized controlled trial (RCT) was conducted. Septic shock patients over 65 years admitted to intensive care unit (ICU) of Shandong Province, Zibo Central Hospital from January 2013 to December 2015 were enrolled. The patients were randomly divided into control group and observation group, 20 cases in each group. In accordance with the guidelines for the treatment of septic shock, early goal-directed therapy (EGDT), rehydration in the control group was treated with the guide of central venous pressure (CVP); observation group was received pulse indicator continuous cardiac output (PiCCO) monitoring, and rehydration was treated according to the GEDVI and extravascular lung water index (EVLWI), i.e. GEDVI was maintained in 650-800 mL/m2, EVLWI was not obviously increased compared with the basic value and without the emphasis of CVP. Initial acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score, sequential organ failure score (SOFA), procalcitonin (PCT), mean arterial pressure (MAP), lactic acid (Lac) and oxygenation index (PaO2/FiO2); serial Lac, central venous to arterial carbon dioxide pressure (Pcv-aCO2), fluid balance, the amount of noradrenaline accumulation, PaO2/FiO2 after 6, 24 and 48 hours resuscitation; mechanical ventilation time, incidence of acute heart failure, ICU hospitalization time and 28-day mortality were recorded. Results There was no significant difference in gender,age, APACHE Ⅱ score, SOFA score, primary disease, infection site and basal PCT, MAP, Lac, PaO2/FiO2 between the two groups. Compared with the control group, 6 hours Lac, Pcv-aCO2 recovery, positive fluid balance, noradrenaline accumulation and PaO2/FiO2 of the observation group showed no significant difference; positive fluid balance 24 hours in the recovery was significantly reduced (mL: 2919.80±986.44 vs. 3991.40±933.53), Pcv-aCO2 significantly decreased [mmHg (1 mmHg = 0.133 kPa): 5.55±1.43 vs. 7.10±2.38], PaO2/FiO2 significantly improved (mmHg: 194.80±28.57 vs. 177.65±23.46), and noradrenaline accumulation was increased significantly (mg: 40.99±20.69 vs. 27.31±19.34) with statistically significant difference (all P < 0.05); the blood level of Lac 48 hours in the recovery was significantly decreased (mmol/L: 1.16±0.89 vs. 1.85±1.01), Pcv-aCO2 (mmHg: 5.35±1.18 vs. 6.70±2.34), and PaO2/FiO2 (mmHg: 215.75±33.84 vs. 190.60±32.89) were further improved, the positive fluid balance was significantly reduced (mL: 3141.55±1245.69 vs. 4533.85±1416.67, all P < 0.05). Compared with the control group, mechanical ventilation time (days: 3.65±1.31 vs. 4.50±1.19), ICU hospitalization time (days: 5.80±1.67 vs. 7.15±2.30) was significantly shorter in the observation group (both P < 0.05), acute heart failure rate was decreased significantly (5.0% vs. 30.0%, P < 0.05), but the 28-day mortality showed no statistical significance (25.0% vs. 40.0%, P = 0.311). Conclusions Compared to the conventional EGDT methods, fluid resuscitation under the guidance of GEDVI in elderly patients with septic shock with less liquid loading, can achieve better oxygenation and reduce heart failure, shorten the duration of mechanical ventilation and ICU stay, and play an important significant guidance for elderly patients' fluid resuscitation with septic shock.

ABSTRACT
Objective To explore the application value of pulse indicator continuous cardiac output (PiCCO) monitoring in the fluid management of children with acute respiratory distress syndrome (ARDS).Methods Thirty-two children with ARDS admitted to Pediatric Intensive Care Unit(PICU) of Zhengzhou Children's Hospital,from April 2013 to April 2016,were divided into intervention group (15 cases) and control group (17 cases) by adopting random number table method.Fluid management of intervention group by PiCCO,control group by central venous pressure,the 2 groups' oxygenation index (OI),acute lung injury score,mechanical ventilation time and 28 days mortality were statistically compared.The categorical data were analyzed by using SPSS 11.0 software,and the t test was used for the measurement data.The categorical data and mortality comparison were analyzed by adopting x2 test.The difference was statistically significant at P ＜ 0.05.Results After 3 days of mechanical ventilation,the changes of OI in the intervention group were significantly higher than those in the control group [(175.0 ±-43.7) mmHg vs.(143.0 ± 42.8) mmHg (1 mmHg =0.133 kPa),t =2.090 0,P ＜ 0.05].The intervention group was significantly shorter than the control group [(10.45 ± 3.12) d vs.(12.63 ± 2.87) d,t =2.058 7,P ＜ 0.05].There was no significant difference between 2 groups in acute lung injury score,PICU length of stay and 28 days mortality (all P ＞ 0.05).Conclusions PiCCO monitoring and guidance in the fluid management of pediatric ARDS can improve oxygenation after 3 days,reduce mechanical ventilation time,but can not significantly reduce the 28-day mortality.
ABSTRACT
Objective To assess the value of end-tidal carbon dioxide partial pressure (PETCO2) combined passive leg raising (PLR) test on volume responsiveness assessment in shocked patients post cardiac operation.Methods A prospective,self-controlled,and observational study was conducted.The shocked patients post cardiac operation undergoing complete mechanical ventilation admitted to Department of Critical Care Medicine of First Affiliated Hospital of College of Medicine,Zhejiang University from June 2014 to October 2015 were enrolled.PETCO2 and hemodynamic parameters including stroke volume variation (SVV),cardiac index (CI),mean arterial pressure (MAP) monitored by a pulse indicator continuous cardiac output (PiCCO) were determined before and after PLR and volume expansion (VE).Volume responsiveness was defined as an increase in CI (△ CI) of 15％ or greater after VE,namely response group (△ CI ≥ 15％) and non-response group (△ CI ＜ 15％).The value of PLR-induced PETCO2 change (△PETCO2 PLH) to predict volume responsiveness was evaluated by receiver operating.characteristic curves (ROC).Results Among the 41 patients enrolled,21 had volume responsiveness (response group),and 20 had no responsiveness (non-response group).After PLR,the changes in CI and PETCO2 were both significantly increased in the response group compared with non-response group [△ CI:(13.5 ± 4.6)％ vs.(3.6± 3.5)％,△ PETCO2:(7.4 ± 3.4)％ vs.(2.8 ± 2.5)％,both P ＜ 0.05].△ PETCO2 PLR and baseline SVV were positively correlated with PLR-induced CI change (△ CI PLR) (r1 =0.50,r2 =0.38,both P ＜ 0.05).VE-induced PETCO2 change (△ PETCO2 VE),baseline SVV and △ CI PLR were positively correlated with VE-induced CI (△ CI VE) (r1 =0.58,r2 =0.56 and r3 =0.84,all P ＜ 0.01).The area under ROC curve (AUC) of △ PETCO2 PLR was 0.875±0.054 [95％ confidence interval (95％CI) =0.769-0.981,P ＜ 0.05].△ PETCO2 PLR ≥ 5.8％ predicted volume responsiveness with sensitivity of 76.2％ and specificity of 90.0％.AUC of △CI PLR was 0.933±0.036 (95％CI =0.862-1.000,P ＜ 0.05).△CI PLR ≥ 10.4％ predicted volume responsiveness with sensitivity of 81.0％ and specificity of 90.0％.AUC of baseline SVV was 0.831 ±0.066 (95％CI =0.702-0.960,P ＜ 0.05).Baseline SVV ≥ 12.5％ predicted volume responsiveness with sensitivity of 85.7％ and specificity of 75.0％.Conclusion The change in PETCO2 induced by PLR is a convenient,reliable and non-invasive indicator to predict volume responsiveness in shocked patients post cardiac operation with mechanical ventilation.
ABSTRACT
Objective To examine the effect of rapid infusion test guided by extravascular lung water index (EVLWI) on hemodynamics in critically ill patients at different states in order to guide volume resuscitation.Methods A prospective observation was conducted.Forty critically ill patients admitted to Department of Critical Care Medicine of Tianjin Third Central Hospital from June 2012 to April 2014 were enrolled.Based on the levels of EVLWI and pulmonary vascular permeability index (PVPI) and the cardiac function,the patients were divided into four groups:septic patients with normal EVLWI and PVPI (n =17),septic patients with increased EVLWI and PVPI (n =3),septic patients with increased EVLWI and normal PVPI (n =4),and coronary heart disease and heart failure patients with normal EVLWI and PVPI (n =16).The rapid infusion test was conducted in all patients using lactated Ringer solution 250 mL,followed by infusion of crystalloid with rate of 150 mL/h.The conditions of mechanical ventilation and vasoactive drugs were not changed during study.The changes in EVLWI,intrathoracic blood volume index (ITBVI),and cardiac index (CI) before capacity load,at immediate capacity load,and 15,45,105 minutes after load were determined by pulse indicator continuous cardiac output (PiCCO).On the base of volume status before and after the liquid infusion,the standard for the changes were:stroke volume (SV) increased by 12％-15％,central venous pressure (CVP) greater ≥ 2 mmHg (1 mmHg =0.133 kPa),CI ＞ 15％,and ITBVI change greater than 10％.Results There were no statistically significant differences in the observed indicators at the each time point before and after rapid infusion test among the four groups (all P ＞ 0.05).In septic patients with normal EVLWI and PVPI group,ITBVI was slightly increased by 5.4％-9.7％ from 15 minutes to 45 minutes after rapid infusion test.In coronary heart disease and heart failure patients with normal EVLWI and PVPI group,the EVLWI was increased by 11.9％,5.9％,and 14.7％ respectirely at 15,45,and 105 minutes,ITBVI was slightly increased by 6.4％ at 45 minutes,CI was increased by 29.5％ immediately after rapid infusion.In septic patients with increased EVLWI and PVPI group,CVP was increased by 8 mmHg immediately,EVLWI was increased significantly by 15.8％ at 45 minutes,ITBVI was slightly decreased by 10.0％ at 45 minutes,CI was increased by 24.7％ immediately,and increased by 17.0％ at 105 minutes,and PVPI was increased by 15.6％-28.1％ at 15-105 minutes after rapid infusion.In septic patients with increased EVLWI and normal PVPI group,CVP was increased by 1.5 mmHg at 15 minutes,EVLWI was increased immediately,which was increased by 17.4％,24.0％,and 31.4％ respectively at 15,45,and 105 minutes,ITBVI was increased by 13.9％ at 15 minutes,CI was increased by 16.1％ at 15 minutes after rapid fluid infusion.Conclusions Rapid fluid replacement in critically ill patients with crystalloid,regardless of whether the EVLWI was normal or increased,the short-term response was affected by the volume and cardiac function of patients.Different status of patients showed different volume effect curve:no significant changes in hemodynamic parameters were found in patients with normal EVLWI and volume parameters.In patients with potential cardiac dysfunction,CI and EVLWI increased significantly; regardless of PVPI increased or normal,EVLWI and CI were increased in patients with elevated EVLWI; two different changes could be found in the two types of pulmonary edema while ITBVI was increased.
ABSTRACT
Objective To investigate the value of employing pulse indicator continuous cardiac output (PiCCO) for cardiac function monitoring in patients with severe septic shock.Methods A prospective observation was conducted.Thirty-six septic shock patients in Department of Critical Care Medicine of Peking University Third Hospital admitted from August 2011 to December 2013 were enrolled.According to the degree of severity,the patients were divided into PiCCO monitor group and routine monitor group.The PiCCO monitor provided a continuous assessment of fluid resuscitation,vasopressors and inotropes infusion in the patients with severe septic shock.The following cardiac function parameters were assessed in severe septic shock patients on the 1st and 3rd day after intensive care unit (ICU)admission:cardiac index (CI),global ejection fraction (GEF),rate of left ventricular pressure increase (dp/dt max),echocardiography,and blood troponin T (TNT) and B-type natriuretic peptide (BNP).The central venous pressure (CVP),mean arterial pressure (MAP) and the time reaching their standard values,and the norepinephrine dosage and 3-day fluid balance in severe septic shock patients were compared between milrinone and non-milrinone usage groups.The severity degree and outcome were compared between PiCCO monitor group and routine monitor group.Results There were 15 patients in PiCCO monitor group and 21 in routine monitor group among 36 septic shock patients.① In 15 patients with PiCCO monitoring,the patients with decreased CI,GEF,and dp/dt max accounted for 40.0％,93.3％,and 33.3％ at 1 day after ICU admission,and accounted for 60.0％,93.3％,and 60.0％ at 3 days after ICU admission,and it showed that CI,GEF,and dp/dt max was not improved at 3 days after ICU admission.Echocardiography showed that 35.7％ patients had lower left ventricular ejection fraction (LVEF) at 1 day after ICU admission,71.4％ and 71.4％ of patients,respectively,had lower early diastolic mitral flow velocity/early diastolic myocardial velocity (E/Em) and early diastolic mitral flow velocity/end diastolic mitral flow velocity (E/A).Three days after ICU admission,80％ of patients with low LVEF value turned to normal,and diastolic dysfunction was ameliorated in 50％ patients.At 1 day after ICU admission,higher TNT was found in 92.9％ of patients,higher BNP in 100％ of patients,and 3 days after ICU admission,71.4％ and 78.6％ patients showed a decrease in TNT and BNP,respectively.② In PiCCO monitor group,there were no significant differences in initial CVP,MAP and their time reaching standard values,norepinephrine dosage between milrinone group (n =8) and non-milrinone group (n =7).However,3-day intake of liquid in milrinone group was significantly higher than that in non-milrinone group (mL:8 324±3 962 vs.4 372±2 081,t =-2.362,P =0.034).③ Compared with routine monitor group,there was a significant elevation in acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,sequential organ failure assessment (SOFA) score,duration of mechanical ventilation,length of ICU stay and 28-day hospital mortality in PiCCO monitor group [APACHE Ⅱ score:20.67 ± 6.15 vs.14.71 ±4.67,t =-3.304,P =0.002; SOFA score:9.53±3.00 vs.7.52± 1.97,t =-2.433,P =0.020; duration of mechanical ventilation (hours):132 (54-310) vs.63 (14-284),Z =-2.295,P =0.022; length of ICU stay (days):7 (4-15) vs.5 (1-14),Z =-2.360,P =0.018; 28-day hospital mortality:26.7％ vs.0,P =0.023].Conclusion With the use of the PiCCO hemodynamic monitoring in patients with severe septic shock,more comprehensive values of blood volume,systemic vascular resistance and cardiac function can be obtained for guiding fluid resuscitation and selection of vasopressor and inotropic drugs.
ABSTRACT
ObjectiveTo evaluate the influence of continuous venovenous hemofiltration (CVVH) on measurement of transpulmonary thermodilution parameters.MethodsA prospective observational study was conducted. Fifty-six patients who received CVVH and hemodynamic monitoring at the same time admitted to the Department of Critical Care Medicine of Tianjin Third Central Hospital from July 2012 to July 2014 were enrolled. In all the patients, the dialysis catheter was inserted through the femoral vein, and transpulmonary thermodilution measurements were performed by pulse indicator continuous cardiac output (PiCCO) monitoring technology at the same time. Mean arterial pressure (MAP), central blood temperature, cardiac index (CI), global end-diastolic volume index (GEDVI), intrathoracic blood volume index (ITBVI) and extravascular lung water index (EVLWI) were measured before CVVH, immediately after CVVH, and 30 minutes after CVVH, respectively.Results In the 56 patients, there were 36 males and 20 females, (66±16) years of old, height of (172±6) cm, body weight of (68±10) kg. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores was 26±6. After CVVH,the central blood temperature was gradually decreased, and blood temperature at 30 minutes after CVVH was significantly lower than that before CVVH (℃: 37.17±1.06 vs. 37.57±1.26,P 0.05]. CI, GEDVI, ITBVI at 30 minutes after CVVH were significantly decreased [CI (mL·s-1·m-2): 57.84±20.50 vs. 63.85±21.84, GEDVI (mL/m2):681±106 vs. 727±100, ITBVI (mL/m2): 851±133 vs. 908±125, allP< 0.05]. CVVH was associated with a decline of 6.01 mL·s-1·m-2 at 30 minutes after CVVH [95% confidence interval (95%CI) = -10.67 to -1.50,P = 0.011]. The declines of GEDVI and ITBVI were observed with 46 mL/m2 (95%CI = -81 to - 11,P = 0.014), 57 mL/m2 (95%CI =-101 to - 13,P = 0.014 ) respectively 30 minutes after CVVH.Conclusions CVVH had no significant effect on the transpulmonary thermodilution measurements of CI, GEDVI, ITBVI and EVLWI. Thirty minutes after the start of CVVH, CI, GEDVI and ITBVI was decreased significantly, but had no effect on EVLWI.

Objective To evaluate the therapeutic effect of early fluid resuscitation under the guidance of pulse indicator continuous cardiac output (PiCCO) on patients with severe acute pancreatitis (SAP).Methods Clinical data of 18 SAP patients (research group),who had undergone fluid resuscitation under the guidance of PiCCO in the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from October 2011 to October 2013,were analyzed prospectively.At the same time,clinical data of 25 cases (control group) that had undergone fluid resuscitation without the guidance of PiCCO from January 2009 to September 2011 were collected retrospectively.The volume of fluid and clinical data were compared between two groups.Results During the first 6 hours,0-24 hours,24-48 hours,and 0-72 hours after intensive care unit (ICU) admission,the research group received larger volume of fluid than that of the control group (mL:2 133 ± 1 593 vs.1 024 ± 421,t=3.337,P=0.002; 5 960 ±2 951 vs.3 767 ± 854,t=3.531,P=0.001; 4 709 ± 1 508 vs.3 863 ± 1 122,t=2.112,P=0.031 ; 14 601 ± 5 095 vs.11 409 ± 2 667,t=2.673,P=0.007).Compared with the control group,the incidence of application of blood purification was lowered [5.56％ (1/18) vs.44.00％ (11/25),x2=7.688,P=0.006],the duration of the systemic inflammatory response syndrome (SIRS) was shortened (days:3.54 ± 2.44 vs.5.62 ± 3.62,t=2.113,P=0.041),acute physiology and chronic health Ⅱ (APACHE Ⅱ) score was significantly declined at 24 hours after admission (11±4 vs.14 ± 5,t=2.104,P=0.042),the blood lactic acid was decreased more significantly after 72 hours (mmol/L:3.10 ±0.55 vs.2.40 ± 1.12,t=2.442,P=0.019),and the length of ICU stay was shortened (days:10 ±9 vs.20 ± 10,t=3.371,P=0.002) in research group.But there was no significant difference in the percentage of the use of vasoactive drugs [16.67％ (3/18) vs.24.00％ (6/25),x2 =0.340,P=0.560],the incidence of invasive mechanical ventilation [50.00％ (9/18) vs.52.00％ (13/25),x2 =0.017,P=0.897],72-hour urea nitrogen changes (mmol/L:-0.33 ± 4.71 vs.-0.09 ± 5.37,t=0.152,P=0.880),and the percentage of abdominal infection [16.67％ (3/18) vs.16.00％ (4/25),x2=0.003,P=0.953] between research group and control group.The mortality in research group was lower than that in control group [5.56％ (1/18) vs.20.00％ (5/25)] without statistical difference (x2=1.819,P=0.178).According to the 2012 Atlanta classification,patients were re-evaluated after 48 hours fluid resuscitation.Six patients in research group developed moderately severe acute pancreatitis,and the incidence was significantly higher than that in control group [33.33％ (6/18) vs.8.00％ (2/25),x2=4.435,P=0.034].The time of mean PiCCO installation was 4.5 days in 18 cases of the research group,and no related complications occurred.Conclusions The PiCCO device may be a useful adjunct for fluid resuscitation monitoring in patients with SAP within 72 hours.Early fluid resuscitation under the guidance of PiCCO may be helpful in improving tissue perfusion,reducing the application of blood purification,as well as shortening length of ICU stay.This program did not increase the risk of invasive mechanical ventilation,and no obvious change in mortality rate was observed.
ABSTRACT
Objective To investigate the clinical application of pulse indicator continuous cardiac output (PICCO) target oriented role monitoring technique on hemodynamics in patients with intractable heart failure.Methods Eighteen patients with intractable heart failure were selected as control group and received regular treatment including internal medicine under monitoring by central venous pressure.Another 18 patients with refractory heart failure were selected as PICCO group and given the internal medicine under PICCO monitoring.Intrathoracic blood volume index(ITBVI),global end diastolic volume index(GEDVI),extravascular lung water index (EVLWI),cardiac index (CFI),N-terminal B type natriuretic peptide precursor(NT-proBNP) and left ventricular ejection fraction(LVEF) were recorded.The data including mortality rate,ventilation time,intensive care time,APACHE Ⅱ score and the re-hospitalization rate were also record at 28th day.Results Compared with before treatment,ITBVI,GEDVI,EVLWI in PICCO group were (1 282.6 ± 196.4) ml/m2,(1 026.8 ±92.1) ml/m2,(12.9 ± 5.5) ml/kg respectively,significant different from that before treatment ((907.4±78.3) ml/m2,t =8.75,P =0.001; (715.2 ±61.8) ml/m2,t =6.48,P =0.003; (6.5 ± 1.2)ml/kg),t =2.94,P =0.033) and they are all back to normal level.The indices of CFI,NT-proBNP,LVEF in PICCO group were improved than before treatment (CFI:(3.1 ±0.5) L/min vs.(4.8 ± 1.3) L/min,t =2.56,P=0.042) ;NT-proBNP:(6 438.3 ±249.5) ng/L vs.(1 371.6 ±87.5) ng/L,t =5.12,P =0.019) ;LVEF:(26.9±3.1)％ vs.(54.3 ±2.5)％,t =2.62,P =0.040)).Mortality at 28th D in PICCO group was 16.7％,lower than that of control group (33.3％,x2 =4.99,P =0.026).The indices of assisted ventilation time,intensive care time,APACHE score of lⅡ and the rehospitalization ratein PICCO group were better than that of the control group ((8.5 ±2.3) dvs.(3.2±0.8) d,t=24.31,P＜0.05;(14.9±2.3) dvs.(8.3 ±2.0)d,t=12.26,P=0.002;(23.4±1.3) vs.(14.7±1.6),t=9.52,P=0.011;38.9％ vs.11.1％; t=5.79,P =0.020).Conclusion PICCO provides effective guidance for intractable heart failure patients hemodynamic monitoring of goal orientation.
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.
ABSTRACT
Objective To explore application of pulse indicator continuous cardiac output(PICCO)in the treatment of septic shock during continuous renal replacement therapy (CRRT).Methods 34 patients with septic shock who underwent CRRT were randomly divided into the control group and the experimental group.Heart rate(HR),mean arterial pressure(MAP)and central venous pressure (CVP) were monitored in the control group.The experimental group were monitored by PICCO technology in addition to conventional monitoring,the hemodynamics parameters were collected such as end-diastolic volume index (GEDI),extravascular lung water index(EVLWI),and systemic vascular resistance index(SVRI),etc.Dehydration volume and supplementary volume were controlled by means of two group's hemodynamics parameters.The change of Acute Physiology And Chronic Health Evaluation-Ⅱ (APACHE Ⅱ),lactate (Lac),saturation of central venous oxygen(SevO2) and oxygenation index (PaO2/FiO2) were observed.Results After treatment of 72h,the decrease of APACHE Ⅱ and lactate in the experimental group was higher than those in the control group,the increase of ScvO2 in the experimental group was higher than those in the control group,the increase of PaO2/FiO2 in the experimental group was evidently higher than those in the control group.Conclusions During PICCO monitoring technique to guide CRRT therapy in patients with septic shock,the volume status of patients can be accurately controlled,organizational cycle can be improved,oxygenation of lung can be obviously improved,which contributes to treatment of septic shock.
ABSTRACT
Shock is the hypoperfusion or blood flow distribution abnormality and leads to systemic tissue hypoperfusion and organ dysfunction.Cardiac output and tissue perfusion pressure are major factors affecting tissue and organ peffusion.Continuous assessment of hemodynamic parameters is crucial for the diagnosis and treatment of shock.The pulse indicator continuous cardiac output technology combines hemodynamic monitoring and volumetric measures to assess a variety of hemodynamic parameters including cardiac output,afterload and volume,which is a kind of low-risk,convenient,accurate,and continuous technology.
ABSTRACT
Objective To explore the correlation between the two methods of pulmonary arterial thermodilution technique(ThDCO)and pulse indicator continuous cardiac output(PiCCO)in determining hemodynamic changes in patients undergoing orthotopic liver transplantation(OLT).Methods Eighteen patients with end-stage liver disease(ASAⅡ-IV)were performed OLT and monitored hemodynamic changes by PiCCO method and ThDCO method simultaneously.The hemodynamic parameters including mean arterial pressure(MAP),cardiac output(CO)and systemic vascular resistance(SVR)were measured at different time points before anesthesia induction,after tracheal intubation,after the beginning of operation,at anhepatic phase,at neohepatic phase,at the end of operation,and after operation.Results Good correlation was found between the two methods for the determination of CO and SVR(r=0.987,P0.05).Conclusion The hemodynamics change dramatically in patients undergoing OLT.There is good correlation between the two methods of PiCCO and ThDCO for perioperative hemodynamic monitoring in patients undergone OLT,and PiCCO detection can be used conveniently for real-time continuous monitoring.
