Objective To investigate and analyze the efficacy of intravenous levosimendan in the treatment of acute cardiac failure after cardiac surgery. Methods The study of the 80 cases of acute heart failure in patients undergoing cardiac surgery after treatment in March 2014 to March 2017, the patients were monitored in the treatment before and after treatment of 24 h heart rate, left ventricular ejection fraction, mean arterial pressure and central venous pressure and other related indicators. Results Of all patients, 58 survived after treatment, and 22 died during or after treatment. Compared with before treatment, after treatment of 24 h in left ventricular ejection fraction in patients, mean arterial pressure, central venous and changes in heart rate were significantly improved, data between the two groups had significant difference compared with statistical significance(P<0.05). In 8 patients, transient blood pressure reduction occurred during treatment, but symptoms disappeared after taking appropriate measures, and other patients had no more severe adverse reactions. Conclusion According to the method of intravenous levosimendan in treatment of acute heart failure in patients undergoing cardiac surgery after treatment can make the patient's cardiac function improved, has a significant effect on the prognosis of patients, should have a relatively high value.

Objective To investigate whether mixed venous-arterial carbon dioxide difference (Pv-aCO2) combined with passive leg raising (PLR) could better guide volume management for patients post off-pump coronary artery bypass grafting (OPCABG).Methods Eighty patients experienced OPCABG, and admitted to Tianjin Chest Hospital from June 1st to October 1st in 2016 were enrolled. They were randomly divided into two groups: observation group given Pv-aCO2 combined with PLR directed therapy and control group given central venous pressure (CVP) directed therapy, 40 cases in each group. The difference in body temperature (T), heart rate (HR), mean arterial pressure (MAP), CVP, oxygenation index (PaO2/FiO2), mixed venous oxygen saturation (SvO2), Pv-aCO2, blood lactate (Lac), fluid intake, scores of the vasoactive agents at 6 hours post-operation, sequential organ failure assessment (SOFA) of 24 hours, mechanical ventilation time, the length of intensive care unit (ICU) stay, and hospitalization time were compared. The correlation between Pv-aCO2 and cardiac index (CI), Pv-aCO2 and Lac were analyzed by Spearman analysis in observation group.Results The T, HR, MAP, CVP, PaO2/FiO2, SvO2 and Lac at 6 hours post-operation were higher than those at admission in two groups, and Pv-aCO2 were significantly decreased. The SvO2 and fluid intake in observation group were higher than those in control group [SvO2: 0.671±0.068 vs. 0.634±0.052, fluid intake (mL): 454±151 vs. 304±106, bothP < 0.05], Pv-aCO2, Lac and scores of the vasoactive agents were lower than those in control group [Pv-aCO2 (mmHg, 1 mmHg = 0.133 kPa): 6.1±1.8 vs. 7.0±1.8, Lac (mmol/L): 1.7±0.5 vs. 2.8±0.6, scores of the vasoactive agents: 3.18±1.01 vs. 4.48±1.50, allP < 0.05], mechanical ventilation time and the length of ICU stay were less than those in the control group (hours: 16.52±6.41 vs. 21.96±9.00, 45.51±9.36 vs. 51.76±13.66, bothP< 0.05). There was no significant difference in SOFA, hospitalization time between the two groups. There was negative correlation with Pv-aCO2 and CI (r = -0.752,P < 0.01), and no correlation with Pv-aCO2 and Lac (r = -0.154,P = 0.171).Conclusion Pv-aCO2 combined with PLR can better guide volume management in the patients post OPCABG, reduce the usage of vasoactive agents and decrease the mechanical ventilation time and the length of ICU stay.

OBJECTIVE To investigate the patterns of catheter related infection in critically ill patients after cardiac surgery with prolonged central venous catheters. METHODS The materials of culture of catheter tip and subcutaneous segments in 166 critically ill patients after cardiac surgery with prolonged central venous catheters were reviewed. RESULTS The positive pathogenic bacteria ratio of catheter tip segments was 41.0% and the positive ratio of catheter subcutaneous segments was 47.0%.Catheterization longer than 18 days,body temperature higher than 38.5 ℃ and insertion sites of femoral veins were the variables associated with significantly increased risk of catheter related infection. CONCLUSIONS The positive pathogenic bacteria ratio of central venous catheters in critically ill patients after cardiac surgery with prolonged central venous catheters is high,more attention must be paid to catheter related infection,and efficacious interventions must be laid down.

OBJECTIVE:To explore the effect of propofol target-controlled infusion on extubation time in patients with ENT surgery under Narcotrend classification guidance. METHODS:52 patients with endotracheal intubation intravenous anesthesia and minimally invasive ENT surgery received target-controlled infusion for anesthesia induction and anesthesia. NI value, plasma concentration of propofol(cm),mean arterial pressure(MAP),pulse oxygen saturation(SpO2)before anesthesia and different time points in recovery period,the correlation of NI with propofol cm of all patients were recorded,and NI with propofol cm and time when extubation was omalysed. RESULTS:There were no significant differences in SpO2 before anesthesia and different time points in recovery period(P>0.05);MAP was significantly higher than before anesthesia at T3,MAP was significantly lower than before anesthesia at T0-T1,propofol cm was T0>T1>T2>T3>T4>T5,NI was significantly lower than before anesthesia at T0-T3, and T00.05). NI when extubation was(86.17±5.29),propofol cm was(0.96±0.31)μg/ml,and average extubation time was (8.26 ± 2.93) min. When extubation,NI showed negative correlation with propofol cm(r=-0.812);and decreased with the prolong of extubation time (r=-0.792);the predictive rates of NI and propofol cm's prediction awareness change in recovery period were 0.93 and 0.86. There were no obvious adverse reactions during treatment. CONCLUSIONS:Propofol target-controlled infusion under Narcotrend classification guidance can accurately predict the awareness change from no response to stimuli to shouting and opening eyes,has a high reference value on extubation time.
