Objective To investigate the effect of carbon dioxide ( CO2 ) pneumoperitoneum on the neuromuscular block of cisatracurium in patients undergoing laparoscopic operation.Methods Sixty ASA Ⅰ or Ⅱ patients,aged 35-60 yr,with body mass index of 18-24 kg/m2,scheduled for elective hysterectomy,were randomly divided into 2 groups ( n =30 each ):pneumoperitoneum group ( group P) and control group ( group C ).Each group was further divided into 2 subgroups according to the use of the antagonist of neuromuscular block ( n =15 each):no neostigmine group ( group P0 or C0 ) and neostigmine group (group P1 or C1 ).Anesthesia was induced with fentanyl,propofol and cisatracurium and maintained with target-controlled infusion of propofol and remifentanil.Tracheal intubation was performed and the patients were mechanically ventilated.Neuromuscular function was monitored by TOF-Watch SX accelerography (Organon Co.,Organon).A train of four (TOF) stimulation of the ulnar nerve was used.When T,returned to 5％ of control height after CO2 pneumoperitoneum was established,cisatracurium 0.05 mg/kg was injected intravenously in group P.When T1 returned to 25％ of control height after the end of operation,neostigmine was injected intravenously in groups P1 andC1.The clinical duration and recovery index were recorded after CO2 pneumoperitoneum was established.Arterial blood samples were obtained immediately before induction,at 30 and 60 min of pneumoperitoneum,and at the end of operation for blood gas analysis.Results The clinical duration and recovery index were significantly longer in group P0 than in group C0,and in group P1 than in group C1 ( P ＜ 0.05).Compared with group C0,the pH value was significantly decreased and PaCO2 was significantly increased at 30 and 60 min of pneumoperitoneum,and at the end of operation in group P0 ( P ＜ 0.05).Compared with group C1,the pH value was significantly decreased and PaCO2 was significantly increased at 30 and 60 min of pneumoperitoneum,and at the end of operation in group P1 ( P ＜ 0.05).Conclusion CO2 pneumoperitoneum can strengthen the neuromuscular block induced by cisatracurium and prolong the recovery time following antangonism by neostigmine administration in patients undergoing laparoscopic operation.

Objective To evaluate the correlation between stroke volume variation (SVV) and the blood volume. Methods Forty-eight ASA Ⅱ male patients, aged 50-60 yr, scheduled for elective radical operation for gastric cancer, were studied. Anesthesia was induced with fentanyl 4 μg/kg, propofol 2 mg/kg and cis-atracurium 0.15 mg/kg and maintained with inhalation of 2%-3% sevoflurane. 6% HES 130/0.4 was infused intravenously at a rate of 0.67 ml· kg - 1 · min - 1 30 min after induction. SVV,cardiac output (CO),SV and cardiac index (CI) were monitored and recorded using the FloTrac/Vigileo (Edwards Lifesciences, USA) system before HES was infused and when the dose of HES reached 2, 4, 6, 8, 10, 12, 14, 16 and 18 ml/kg. CVP was also recorded at the corresponding time points. Spearman's rank sum correlation coefficient was used to analyze the data. Results Correlation coefficients between the amount of HES infused and CO, SV, CI or CVP were rSVV = - 0.91 ± 0.06,rCO = 0.83 ± 0.04, rSV = 0.86 ± 0.09, rCI = 0.86 ± 0.09 and rCVP = 0.90 ± 0.03. Among the 5 correlation coefficients, rSVV was the highest, rCVP was significantly higher than rCO, rSV and rCI (P ＜ 0.05), and there was no significant difference among rCO, rSV and r CI (P ＞ 0. 05). Conclusion SVV is highly correlated with the blood volume and can be used to guide volume therapy.

Objective To evaluate the effect of obesity on the potency of propofol for sedation.Methods Sixty patients of both sexes, aged 35-55 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective operation under general anesthesia, were enrolled in the study.The patients were divided into 2 groups (n=30 each) according to the body mass index (BMI) : normal body weight (BMI ＜ 25 kg/m2) group (group C) and obesity (BMI 30-40 kg/m2) group (group O).No patients received premedication.Propofol was given by target-controlled infusion.The initial target plasma concentration of propofol was set at 1.2 μg/ml.After the target concentration was steadily maintained for 30 s, it was increased in 0.3 μg/ml increment until the patients lost consciousness (OAA/S score =1).The target plasma concentration of propofol was recorded during each period.The median effective concentration (EC50) and 95％ confidence interval of propofol for loss of consciousness was calculated using probit analysis.Results The EC50 and 95％ confidence interval of propofol for loss of consciousness were 3.82 (3.73-3.90) and 3.29 (3.20-3.37) μg/ml in group C and group O, respectively.Compared with group C, the EC50 was significantly decreased in group O (P＜0.05).Conclusion Obesity can enhance the potency of propofol for sedation.

Objective To evaluate the accuracy of stroke volume variation (SVV) in monitoring the changes in blood volume during laparoscopic surgery.Methods Forty ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 40-64 yr,with body mass index ranged from 20 to 25 kg/m2,scheduled for elective laparoscopic surgery under general anesthesia,were studied.After induction of general anesthesia,baseline registrations of variables were obtained.After establishing pneumoperitoneum,6％ hydroxyethyl starch (HES 130/0.4) 500 ml was infused over 30 min.Before pneumoperitoneum (T1),at 5 min after pneumoperitoneum (T2),immediately before volume expansion (T3) and at 3 min after volume expansion (T4),cardiac output (CO),cardiac index (CI),SV,stroke volume index (SVI) and SVV were monitored and recorded.The changing rate of CI (△CI) was calculated.The criterion for effective volume expansion was △CI ≥ 15％.The ROC curve for SVV in determining the volume expansion responsiveness was plotted,and the diagnostic threshold was determined.The area under the curve and 95％ confidence interval were calculated.Results SVV was significantly lower at T2 than at T1.CO,CI,SV and SVI were significantly higher,and SVV was lower at T4 than at T3.The results of ROC curve analysis showed that a 9.2％ SVV threshold discriminated between responders and non-responders with a sensitivity of 61％ and a specificity of 50％,and the area under the curve (95％ confidence interval) was 0.567 (0.378-0.757).Conclusion SVV is not a suitable index in monitoring the changes in blood volume during laparoscopic surgery.

Objective To determine the optimal dose of oxycodone for patient-controlled intravenous analgesia (PCIA) after gastrointestinal surgery when combined with dexmedetomidine in elderly patients.Methods Sixty patients of both sexes,aged 65-80 yr,weighing 50-75 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,undergoing elective open gastrointestinal surgery,were divided into 3 different doses of oxycodone groups (group O1,group O2 and group O3,n=20 each) using a random number table.At 15 min before the end of surgery,oxycodone 0.1 mg/kg was intravenously injected,and PCIA pump was connected simultaneously.In O1,O2 and O3 groups,the PCIA solution contained dexmedetomidine 2.0 μg/kg and oxycodone 0.3,0.5 and 0.7 mg/kg in 100 ml of 0.9％ normal saline,respectively.The PCIA pump was set up to deliver a 0.5 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Oxycodone 0.05 mg/kg was intravenously injected as a rescue analgesic after surgery,postoperative pain was assessed using a verbal rating scale,and the verbal rating scale score was maintained ≤4.The number of successfully delivered doses and requirement for rescue analgesics were recorded within 48 h after surgery,and the rate of rescue analgesia was calculated.The occurrence of adverse reactions such as nausea,vomiting,dizziness,respiratory depression,somnolence,bradycardia,hypotension and over-sedation was recorded.Patients' satisfaction with analgesia at postoperative 72 h and the length of postoperative hospital stay were also recorded.Results Compared with group O1,the rate of rescue analgesia after surgery and the number of successfully delivered doses were significantly decreased,and the degree of patients' satisfaction with analgesia was increased in O2 and O3 groups,and the incidence of nausea and somnolence was significantly increased in group O3 (P＜0.05).Compared with group O2,no significant change was found in the rate of rescue analgesia after surgery or the number of successfully delivered doses (P＞0.05),and the incidence of nausea and somnolence was increased in group O3 (P＜0.05).Conclusion When combined with dexmedetomidine 2.0 μg/kg,the optimal dose of oxycodone for PCIA is 0.5 mg/kg after gastrointestinal surgery in elderly patients.

Objective To analyze the related factors of micro-albuminuria and macroalbuminuria in type 1 diabetes mellitus (DM) in the classification tree model,and to screen the high risk population of diabetic kidney disease.Methods 394 patients with type 1 diabetes were enrolled in the hospital from 2008 to 2015.According to glomerular filtration rates and urine albumin quantification,the patients were divided into type 1 diabetes group (299 cases),micro-albuminuria group (73 cases) and macro-albuminuria group (22 cases).The classification tree model was utilized to analyze related factors of the different stages of proteinuria,and the high-risk population was screened by node gain analysis.Results Four important explanatory variables were screened out by the classification tree model from the 27 candidate variables related to primary renal damage,including retinopathy,fibrinogen,waist-hip ratio (WHR),red blood cell distribution width (RDW).Retinopathy was an major factor of DKD.The probability of macro-albuminuria in retinopathy and WHR ＞ 0.82 group was 43.8％,and if at the same time RDW ＞ 0.14,the probability of macro-albuminuria was 88.9％.Conclusions The classification tree model can analyze factors of the separate stages of proteinuria in type 1 diabetic patients effectively.Retinopathy is the major influential factors of type 1 diabetic patients with proteinuria.

Objective To investigate which cells persistantly express interleukin (IL)-1β during the transition of acute neuroinflammaiton to chronic neuroinflammaiton and therefore to provide the evidences of targeted therapy for blocking neuroinflammation.Methods A single does of lipopolysaccharide (LPS) (2 mg/kg,LPS group) or 0.9％ saline (Control group) was intraperitoneally injected in aged rats.Level and gene expression of IL-1β in hippocampual tissue were measured by enzyme-linked immunosorbent assay (ELISA) and real time polymerase chain reaction (RT-PCR),respectively.Cells secreted IL-1β in hippocampus was detected via double fluorescence.Results Glial fibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule-1 (IBA-1) positive cells were significantly increased day 1 (P ＜ 0.05) and latee on,gradually return to base level 30 days after LPS exposure.These changes were consistent with mRNA expressions of IL-1β and astrocytes-derived IL-1β in hippocampus.Neither IL-1β expressed in microglia nor in neurons was observed at any time point following LPS-treated.Conclusions LPS induces prolonged activation of glial cells and sustained expression of astrocytes-derived IL-1β,which may play an important role in the transition of acute neuroinflammation to chronic neuroinflammation.
