Results The average dose of Fentanyl was (13.3?7 3)?g/kg Six (42.9%) of 14 cases were extubated at the operating room, while other 8 cases (57.9%) were extubated (4.71?2.21) hours after operation. The time of ICU stay was (45.2?35.5) hours. No anesthesia related complications were found perioperatively. Conclusions "Fast track" anesthesia technique is suitable for VATCABS.

Objective To determine the risk factom for the development of systemic inflammatory response syndrome(SIRS)in patmnts after off-pump coronary artery bypass grafting(OPCABG).Methods Sixty NYHA Ⅰ or Ⅱ patients,aged 46-73 yr,weighing 54-110 kg,undergoing OPCABG,were studied.Blood samples from intemal iugular vein were taken for determination of the plasma concentrations of IL-6 and IL-10 at 4 h after the surgery by ELISA.SIRS 8COre W88 performed during 24 h after the surgery.The patients were divided into 2 groups:SIRS group(S,SIRS 8core≥2)and non-SIRS group(U,SIRS score<2).Factors including age,sex,weight,percentage of mononuclear cells,concentration of hemoglobin,time of operation,left ventricular ejection firction,whether using proteinase inhibitor or not during surgery and plasma concentrations of IL-6 and IL-10 at 4 h after surgery were reccorded.The risk factors were identified by logistic regression analysis.Results Logistic analysis indicated that percentage of mononuclear cells,concentration of hemoglobin,the plasma concentrations of IL-6 and IL-10 were closely related with the development of SIRS in patients after 0PCABG(P<0.05),Y=0.155+0.52 X1+0.39 X2+0.76X1-0.79X,Conclusion The percentage of mononuclear cells,concentration of hemoglobin,and plasma concentrations of IL-6 and IL-10 after surgery Call be the risk factors for the development of SIRS in patients after OPCABG.

Objective To investigate the effects of intraoperative intravenous ulinastatin infusion on perioperative lung function in patients undergoing off-pump coronary artery bypass grafting (OPCABG). Methods Twenty-four NYHA class Ⅰor Ⅱ patients aged 65-75 y undergoing elective OPCABG were randomly divided into 2 groups(n=12 each): control group (C) and ulinastatin group (U). In group U, after tracheal intubation the patients received iv injection of ulinastatin 6 000 U/kg over 30 min followed by iv ulinastatin infusion at 1 000 U·kg-·h-1 until the end of surgery. In group C equal vohtme of normal saline was administered iv instead of ulinastatin. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring and blood sampling. The patients were premeditated with intramuscular morphine 10 mg. Anesthesia was induced with midazolam 0.1 mg/kg, fentanyl 10 μg/kg and pipecuronium 0.1 mg/kg and maintained with 1%-2% sevoflurane in 70% O2 and intermittent iv boluses of fentanyl and pipecuronium. Blood samples were taken before (T1) and at the end of operation (T2) and at 4, 8, 20 h after operation (T3.5) for determination of plasma CD11/CD18 expression, plasma IL-6 and serum NO concentrations, and blood gases. P(A-a) O2 and respiratory index (RI) (RI=P(A-a)O2/PaO2) were calculated. Mechamcal ventilation time in ICU was recorded. Results The two groups were comparable with respect to age, sex, body weight, duration of anesthesia and surgery, and the number of bypass grafts. The plasma level of IL-6, and expression of CD11 b/CDI8 were significantly increased while serum NO level was significantly decreased after operation as compared to the baseline values before operation (T1) in group C. There was no significant change in the plasma levels of IL-6, CD11b/CDI8 expression and serum levels of NO after operation in group U. P(A-a)O2 and RI were significantly increased after operation in both groups and were significandy lower in group U than in group C. The mechanical ventilation time in ICU was significantly shorter in group U than in group C. Conclusion Intravenous ulinastatin inihsion can significantly protect lung function during OPCABG by inhibiting inflammatory response.

Objective To evaluate the effect of gender and treatment strategy on remote ischemic preconditioning (RIPC)-induced reduction of myocardial damage in patients undergoing cardiac surgery.Methods We systematically searched the literature in PubMed,EMBase,and Cochrane Library (from Feb 1990 to Feb 2012) using the related keywords.Randomized control trials (RCTs) published in English with report on postoperative biomarkers of myocardial damage concerning RIPC-induced myocardial protection in adult patients undergoing cardiac surgery were included.Standardized mean difference (SMD) was calculated.Publication bias and sensitivity analysis were used to evaluate the reliability of overall enzymatic estimate.Meta-regression analysis was performed to explore the potential sources of significant heterogeneity among results of studies.Data were analyzed using Stata 12.0.Results Thirteen RCTs involving 985 patients were included in our study.Compared with controls,RIPC significantly reduced postoperative serum levels of biomarkers of myocardial damage with significant heterogeneity (SMD=-0.539; 95％CI:-0.926to-0.152; P＜0.05; I2 =88.7％,P＜0.01).No evidence of obvious publication bias was observed (P =0.083,Begg' s test; P =0.077,Egger' s test).Sensitivity analysis showed that each individual study produced no effect on the direction and magnitude of the overall effect size (P ＜ 0.05).Meta-regression analysis revealed that male (％) (coefficient =0.02 ; 95 ％ CI:-0.002-0.042 ; P =0.070 ; adjusted R2 =19.61％) and total ischemic time (min) (coefficient=-0.08; 95％CI:-0.154-0.002; P =0.055; adjusted R2 =19.47％) were the two major influential factors.Conclusion Gender affects RIPC-induced reduction of myocardial damage after cardiac surgery in patients,RIPC-induced reduction of myocardial damage infemale patients is superior to that in male patients and a better efficacy can be achieved by prolonging the single ischemic time or by increasing the ischemic cycles.
