Objective: To evaluate the feasibility and safety of postoperative patient-controlled epidural analgesia (PCEA)in children. Methods: Forty postoperative pediatric patients(5-11 years old)were divided into two groups. A and B. Both wereinstituted with postoperative PCEA with LCP model (loading dose 2.05 + 0.13ml), continuos infusion rate 0.82 + 0.15mi/h, PCA dose 0.81 + 0.16ml)by Graseby-9300 PCA pump. The PCEA solution of group A was 0.075% bupivacaine plus0.0012 % buprenorphine, that of group B was same while 0. 005% droperidol was added as an adjuvant. Results:The volumeof PCEA sdution consumption in group B was significantly less than that in group A on the first and second postoperative day (P< 0.01-0.05). Good analgesic efficiency with little side effects was obtained, as evaluated by the VASF emasay or D/D score and complications in two groups, but the analgesic effect of group B was better than that of group A. Conclusion: Thepediatric PCEA with low concentration of bupivaeaine plus buprenorphine is feasible and safe. Droperidol may enhance theanalgesic effects of PCEA.

Objective:To evaluate the safety of patient controlled epidural analgesia (PCEA)for elderly patient. Method: Forty two adult patients after operation were divided into control group(44.4?7.8a)and old group(70.9?5.la) according to their ages. All patients reeeived epidural 0.125% bupivacaine and 0.01% morphine mixture for PCEA. BP,HR, RR and SpO_2 were monitored for the first 24 hours following PCEA. Result: The dosage of the mixture was 33.3?6.8ml in control group and 31.6?8.7ml in old group. BP,HR didn't alter markedly in both groups throughout the whole period. RR and SpO_2 remined normal levels. Conclusion: With adequate dosage PCEA can be used safely for elderly postoperative analgesia

Objective To study the early and mid-term outcome in terms of left ventricular(LV)geometry and function in patients with transposition of great arteries with intact ventricular septum (TGA/IVS) undergoing arterial switch operation.Methods Twenty patients were followed up and divided into 2 groups according to age:the earlier group and the later group.Age and sexual matched controls were also designed as control group 1 and control group 2.LV posterior wall thickness(PWTd),dimension(LVIDd)and length(L) at end diastolic phase,LV end-diastolic volume (EDV),end-systolic volume (ESV),ejection fraction (EF),mitral valve early (E) and late (A) inflow velocities and E/A,isovolumic relaxation time (IVRT) were obtained by two-dimensional echocardiography,normalized isovolumic relaxation time (IVRTn),wall thickness index (PWTd/LVIDd) and LV geometry index(LVIDd/L) were calculated,and these indexes between groups were compared.Results ①Compared with control group 1,PWTd in earlier group was higher [(0.41 + 0.06)cm vs (0.36 + 0.05)cm,P =0.022],but LVIDd had no significant statistical difference [(2.08 + 0.21)cm vs (2.21 + 0.23)cm,P =0.117],indicating PWTd/ LVIDd differed between groups(0.20 + 0.04 vs 0.16 + 0.01 P =0.001).②No abnormalities were observed in later group.③Compared with different age groups in TGA,EDV,ESV,L,LVIDd,PWTd were significantly higher in later group(P =0.000).There were obvious correlations between EDV,ESV,L,LVIDd and examined age (r =0.90,0.83,0.73,0.90,P =0.000,R2 =0.809,0.694,0.528,0.808) while there were no significant correlation between PWTd and examined age(r =0.56,P =0.000,R2 =0.309).Conclusions Early after operation,LV is undergoing hypertrophy or hyperplasia in TGA/IVS,but will recover in the mid-term period,and the function is normal all the time indicating that the LV myocardium may avoided irreversible pathological changes if operated in time.All in all,LV develops well in mid-term period.

Objective To investigate the effect of flurbiprofen axetil on perioperative plasma levels of prostaglandin E2 (PGE2) and β-endorphine (β-EP) in patients after remifentanil-based anesthesia.Methods Sixty ASA Ⅱ patients of both sexes,aged 40-64 yr,weighing 50-75 kg,undergoing resection of esophageal cancer,were randomly divided into 3 groups (n =20 each):intralipid group (group A),flurbiprofen axetil pretreatment + postoperative analgesia with flurbiprofen axetil group (group B) and flurbiprofen axetil pretreatment group (group C).Anesthesia was induced with propofol,remifentanil and rocuronium and maintained with propofol,remifentanil and intermittent iv boluses of rocuronium.In group A,intralipid 0.2 ml/kg was injected intravenously at 30 min before operation and patient-controlled intravenous analgesia (PCIA) with fentanyl 15μg/kg + intralipid 0.2 ml/kg was used for postoperative analgesia.In group B,flurbiprofen axetil 2 mg/kg was injected intravenously at 30 min before operation and PCIA with fentanyl 15 μg/kg + flurbiprofen axetil 2 mg/kg was used for postoperative analgesia.In group C,flurbiprofen axetil 2 mg/kg was injected intravenously at 30 min before operation and PCIA with fentanyl 15 μg/kg + intralipid 0.2 ml/kg was used for postoperative analgesia.PCIA solution contained fentanyl 15 μg/kg,flurbiprofen axetil 2 mg/kg and intralipid 0.2 ml/kg in 100 ml of normal saline.The PCA pump was set up with a 0.5 ml bolus dose,a 10 min lockout interval and background infusion at a rate of 2 ml/h after a loading dose of 5 ml starting from 30 min before the end of operation.VAS score was maintained ＜ 3 after operation,and tramadol 50 mg was injected intravenously when VAS ≥ 4 after operation.The amount of remifentanil used during operation and the number of successfully delivered doses and the number of attempts,requirement for tramadol,apnea and severer hypotension were recorded within 48 h after operation.Blood samples were taken immediately before induction of anesthesia,at the end of operation,24 and 48 h after operation (T1-4) for determination of plasma β-EP and PGE2 concentrations.Results There was no significant difference in the amount of remifentanil used among the three groups (P ＞ 0.05).Compared with group A,the number of successfully delivered doses,the number of attempts and the requirement for tramadol were decreased,and the concentration of plasma PGE2 at T2,3 were significantly decreased in groups B and C,and the concentrations of plasma β-EP at T3,4 in group B and at T4 in group C were significantly increased (P ＜ 0.05).Compared with group B,the number of successfully delivered doses,the number of attempts and requirement for tramadol were significantly increased,and the concentration of plasma β-EP at T3,4 wassignificantly decreased in group C (P ＜ 0.05).Compared with the baseline value at T1,the concentrations of PGE2 were significantly increased at T2,3,and the concentration of plasma β-EP was significantly increased at T2,but decreased at T4 in group A,and the concentrations of β-EP at T3,4 were significantly increased in group B (P ＜ 0.05).There was no significant difference in the concentrations of PGE2 and β-EP between the four time points in group C (P ＞ 0.05).Apnea and severer hypotension were not found in the three groups.Conclusion The mechanism by which flurbiprofen axetil reduces postoperative opioid tolerance in patients after remifentanil-based anesthesia may be related to the decrease in PGE2 levels and increase in β-EP levels.

Objective To observe the effect of Tongfu Xiere Recipe (TXP) combined with routine treatment on cytokine level in patients with acute lung injury due to surgery disease of chest. Methods Fifty eight patients with acute lung injury due to surgery disease of chest were randomized into two groups. The two groups received routine treatment subjecting to the Guideline (2006) for Diagnosis and Treatment of Acute Lung Injury/Acute Respiratory Distress Syndrome. The treatment group additionally received TXP (mainly composed of Radix et Rhizoma Rhei, Natrii Sulfas, Fructus Gardeniae, Caulis Lonicerae, Herba Taraxaci, Semen Raphani, Semen Lepidii seu Descurainiae, Rhizoma Polygoni Cuspidati, Radix Paeoniae Rubra, Fructus Aurantii Immaturus, and Cortex Magnoliae Officinalis) for 5 days or till oxygenation index recovered to the normal. The therapeutic effect was evaluated after treatment, and the changes of blood tumor necrosis factor ? (TNF-?), interleukin 6 (IL-6) and interleukin 8 (IL-8) levels were observed before and after treatment. Results The serum levels of TNF-?, IL-6 and IL-8 in the two groups after treatment were decreased (P0.05). Conclusion The therapeutic effect of traditional Chinese medicine integrated with western medicine is superior to the western medicine only for acute lung injury due to surgery disease of chest. TXP can regulate the immune function and relieve the pulmonary inflammation and injury by decreasing the blood levels of TNF-?, IL-6 and IL-8, thus enhance the therapeutic effect of western medicine.

Objective To investigate the protective effects of creatine phosphate pretreatment on circulato ry function in prone position in elder patients with general anesthesia.Methods Forty patients in ASA physical status Ⅰ or Ⅱ of male and female,aged 60 to 75 years undergoing percutaneous nephrolithotripsy in prone position,were randomly divided into two groups (n =20 each):the control group (gToup N) and the creatine phosphate group (group P).In the group P,creatine phosphate sodium (30 mg·kg-1 in 50 mL normal saline) was continuous infused at a speed of 100 mL· h-1,while only normal saline 50 mL in the group N at the same time.HR,MAP,CO,SV,CVP,Pulse Pressure Variation (PVV) and Systemic Circulation Resistance (SVR) were monitored and recorded at 1 min before prone position (T0) and 1 min (T1),3 min (T2),5 min (T3),10 min (T4) after prone position.The requirement for vasoactive agents were also recorded.Results Compared with T0,HR began to increase significantly at T1 in the group N(P ＜ 0.05),while MAP,CO and SV began to decrease at T1 to T3,and CVP,PVV and SVR began to increase significantly at the same time in the group N (P ＜ 0.05).Compared with the group N,MAP,CO and SV were decreased,PPV,CVP and SVR were increased significantly at T1 to T2 in the group P (P ＜ 0.05).The requirement for vasoactive agents in the group P was obviously lower than that in the group N (P ＜ 0.05).Conclusion Creatine phosphate pretreatment can stabilize the hemodynamic change effectively,and prevent the adverse cardiovascular events caused by prone position in elder patients with general anesthesia.
