Objective To compare the effects of a single injection of palonosetron and tropise-tron to prevent postoperative nausea and vomiting (PONV ) in gynecological surgeries. Methods Sixty patients undergoing elective major gynecological surgeries with general anesthesia (Apfel score ≥ 3 ) were included and randomized to group P (palonosetron ) and group T (tropisetron),30 patients in each group.All patients received general anesthesia with tracheal intuba-tion,and palonosetron 0.25 mg or tropisetron 5 mg were injected before anesthesia respectively in two groups.Intravenous hydromorphine was delivered for postoperative analgesia in all patients. PONV were evaluated and followed up for 72 hours.The degree of PONV was recorded and the com-plete response rate (CR)and complete control rate (CC)were calculated.Results The degree of PONV in 0-24 h and 24-48 h was milder in group P than in group T (P <0.05),while in 48-72 h the degree of PONV was similar between the two groups.In group P,5 patients had vomiting postopera-tively with the failure period of treatment of (1 9.6±9.4)h,and no patients needed rescue treatments. While in group T,1 9 patients suffered from vomiting with the failure period of treatment of (20.6± 4.5)h,and rescue treatments were delivered 3 times in total.The CR and CC of preventing PONV in 0-24 h,24-48 h and 0-72 h were significantly higher in group P than in group T (P <0.05).The CR and CC of the two groups were comparable in 48-72 h postoperatively.Conclusion A preoperative single dose of palonosetron 0.25 mg is better than tropisetron 5 mg in preventing PONV within 48hours after gynecological surgery.

ObjectiveTo summarize and analyse the perioperative management especially theanesthesia of 20 kidney transplant recipients in non-transplant surgery. MethodThe anesthesia management of 20 kidney transplant recipients in non-transplant surgery was analyzed retrospectively. ResultsIn 20 cases, 1 case (5％) was performed under local anesthesia,4 cases (20％) were performed under intravertebral anesthesia and 15 cases (75％) were performed under general anesthesia. The operation time was 30-260 min, all cases were managed successfully. ConclusionIt is still a clinical challenge to deal with the surgical patients after kidney transplantation, and it needs fully understanding of the pathophysiological status of the patient and closely collaboration of transplant physicians, anesthesiologists and the surgeons.

ObjectiveTo investigate the effect of ketamine on nicotine-induced current in rat superior cervical ganglion neurons.MethodsNewborn Wistar rats were used in this study.Neurons were isolated enzymatically from superior cervical ganglia of newborn rats in an aseptic condition and cultured in 90％ DMEM/F12,10％ horse serum containing penicillin 100 μg/ml for 5-7 d.Nicotine-induced current was measured and recorded using whole-cell patch clamp technique.A mixture of nicotine 50 μmol/L and different concentrations of ketamine ( 10,25,50,100 μmol/L) was added to the isolated neurons.The effect of ketamine on nicotine-induced current was evaluated.ResultsNicotine-induced peak current was inhibited by ketamine in a concentration-dependent manner.The time constant of fast and slow desensitizing phase of the nicotine acetylcholine receptor was shortened after being exposed to the mixture of nicotine 50 μmol/L + 50 or 100 μmol/L ketamine as compared to nicotine 50 μmol/L-induced current.The median effective concentration of ketamine inhibiting nicotine-induced current was less than 20 μmol/L.ConclusionKetamine can decrease nicotine-induced current in rat superior cervical ganglion neurons in a concentration-dependent manner indicating that inhibition of sympathetic activity is involved in the mechanism of decrease in BP by ketamine in specific condition.

ObjectiveTo observe the effect of penehyclidine hydrochloride (PHC) on serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α ) concentrations following tourniquet deflation in patients undergoing lower limb surgery.Methods Thirty adult patients,scheduled for unilateral lower limb surgery,ASA classification [ - Ⅱ grades,were divided into control group and research group by random number table,each group of 15 cases.Before anesthesia 30 min,PHC in intravenous infusion of 0.01-0.02 mg/kg in research group,the corresponding volume in intravenous infusion of 0.9% sodium chloride in control group.Peripheral venous blood samples were collected immediately before tourniquet inflation (T0,baseline),immediately before tourniquet deflation(T1),30 min (T2) and 60 min (T3) after tourniquet deflation.Serum IL-6 and TNF- α concentrations were measured by enzyme linked immunosorbentassay.ResaltsSerum TNF- α change at the same time point after tourniquet deflation was not statistically significant between two groups (P ＞ 0.05).Serum IL-6 concentration was decreased at each time point after tourniquet deflation compared with T0 in research group,while increased in control group.Serum IL-6concentration difference of T3 and T0 had statistically significant between research group and control group [ (-8.8 ± 5.6) ng/L vs.( 10.2 ± 6.7) ng/L,P＜ 0.05].ConclusionsPHC in advance can decrease serum IL-6 concentration after tourniquet deflation in patients undergoing lower limb surgery.

Objective To evaluate the efficacy for patient controfled intravenous analgesia(PCIA) of butorphanol combined with fentanyl in the patients underwent thoracic surgery .Methods Ninety ASA I --1I patients scheduled for elective thoracic surgery under general anesthesia were randomly allocated into three groups,each group including 30 patients.Group B received butorphanol O.15 mg/ml,group F received fentanyl 20μg/ml,group BF received butorphanol 0.1 mg/ml combined with fentanyl 10μg/ml.PCIA was initiated just before the beginning of skin suturing with a loading dose of 1 ml,continuous rate was 1 ml/h,bolus was 0.5 ml,and lockout time WaS 10 minutes.VAS,sedative scores,respiratory frequency,saturation of blood oxygen,press times,pain-killer dose,side effects and satisfaction to analgesia at 1,4,8,12,24 and 48 hours after operation were recorded. Results VAS in group B WaS significandy higher than that in group F and group BF at 1,4,8 and 12 hours after operation(P＜0.05),and there WaS no significant differ-ence betweengroup Fand group B F(P＞0.05).Thesedative scoresin group B and B Fwere higherthanthat in group F,but no excess sedation WaS found in the former two groups.At the same time,the satisfaction to analgesia was the lowest in group B,the highest in group BF and higher in group F.There were no incidence of nausea,vomiting and pruritus in group B and group BF,but pruritus WaS 16.7%and nausea,vomiting was 23.3%in group F.Conclusions Butorphanol combined with fentanyl Can improve analgesia efficacy and reduce fentanyl adverse incidence.It Can provide the better balance between pain relief and side effects after thoracic surgery.

Objective To analyze the risk factors of acute kidney injury after orthotropic liver transplantation for adult benign end-stage liver disease.Methods A retrospective analysis was conducted in 30 recipients (18 males,12 females,aged 23-68 years,ASA grade Ⅲ or Ⅳ) who underwent orthotropic liver transplantation for benign end-stage liver disease at Tongji Hospital from May,2014 to December,2014.Both demographic characteristics and perioperative parameters were collected,including general condition,surgery and anesthesia factors and intraoperative salvage autotransfusion or not.Perioperative laboratory findings related to renal function including urine volume,serum creatinine (Scr) and urea nitrogen (BUN) were collected,too.All variables tested in the univariate analysis with a P<0.10 were included in a multiple logistic regression analysis.Results There were less intraoperative salvage autotransfusion,more platelet transfusion and a higher using rate of vasopressors in the AKI group after surgery than those did not.Patients who received intraoperative salvage autotransfusion had 0.058 time odds (95%CI 0.005-0.649) of AKI than those did not;patients who required platelet transfusion had 10.706 times higher odds (95%CI 1.212-94.963) of AKI than those did not.Conclusion It is likely that intraoperative salvage autotransfusion was able to decrease the morbidity of AKI,while platelet transfusion and vasopressor administration to maintain blood pressure could increase the possibility of AKI.

Objective To evaluate the effect of different intravenous analgesia methods on postoperative incisional and uterine contraction pain after cesarean section.Methods Four hundred parturients (ASA Ⅱ-Ⅱ) undergoing cesarean section were randomly allocated into 4 groups,including sufentanil group (group S,96 cases),sufentanil combined with flurbiprofen axetil group (group SK,99 cases),butorphanol group (group N,106 cases) and butorphanol combined with llurbiprofen axetil group (group NK,99 cases).All the parturients received the operation under epidural combined with spinal anesthesia,and received patient-controlled intravenous analgesia (PCIA) after cesarean section.Numerical rating scale (NRS) of postoperative rest and dynamic incisional pain and uterine contraction pain,Ramsay sedation scale (RSS),and PCIA-related adverse events were recorded for 24 h after operation.Results All the parturients were finished this study.The age,body weight,gestational weeks and operative time in 4 groups had no significant difference (P ＞ 0.05).The NRS score of rest incisional pain was equivalent among the 4 groups (P ＞ 0.05).The NRS score of dynamic incisional pain after operative 13 h in group S was significantly lower than that in group N[(3.6 + 1.3) scores vs.(5.4 + 1.2) scores](P＜ 0.05).The NRS score of uterine contraction pain after operative 4,13 h in group N and group SK was lower than that in group S [(1.3 ± 1.0),(1.1 ± 0.9) scores vs.(2.5 ± 1.1) scores and (1.6 ± 1.0),(1.4 ± 0.9) scores vs.(2.9 ± 1.1) scores] (P ＜ 0.05).The RSS scores and incidence rate of dizziness were significantly higher in group N than those in group S (P ＜0.05).No abnormality of new-horn infant was recorded in 4 groups.Conclusion Sufentanil combined with nonsteroidal antiinflammatory drugs can perform effective and safe analgesia on postoperative incisional and uterine contraction pain after cesarean section.

Objective To evaluate the role of ATP-sensitive potassium (KATP) channel in spinal dorsal horn neurons in hyperalgesia after thoracotomy in rats.Methods Twenty-eight Sprague-Dawley rats,aged 7-9 weeks,weighing 250-350 g,in which intrathecal catheters were successfully implanted without complications on 14th day after chronic post-thoracotomy pain was induced,were randomly divided into 4 groups (n =7 each):control group,the solvent dimethyl sulfoxide (DMSO) group,KATP channel opener pinacidil group (group P) and KATP channel blocker glibenclamide group (group G).10％ DMSO 10 μl,pinacidil 10 μg/10 μl and glibenclamide 50μg/10μ1 were injected intrathecally in groups DMSO,P and G at 5 day after the intrathecal catheter was implanted,respectively.Paw withdrawal threshold to von Frey filament stimulation was measured before intrathecal administration and at 10,30 and 60 min after intrathecal administration and the acetone test was performed.Coldinduced pain threshold was measured.Results There was no significant difference in paw withdrawal threshold to yon Frey filament stimulation at each time point among the four groups (P ＞ 0.05).Compared with C and DMSO groups,cold-induced pain threshold was significantly increased in group P and decreased in group G (P ＜ 0.05).There was no significant difference in cold-induced pain threshold between C and DMSO groups (P ＞ 0.05).Conclusion KATP channel in spinal dorsal horn neurons is involved in the maintenance of hyperalgesia after thoracotomy in rats.
