ABSTRACT
Objective To compare the effectiveness of postoperative analgesia and early rehabil-itation between the wound infiltration combined with intravenous analgesia and epidural analgesia after hepatectomy.Methods Forty-eight patients with liver carcinoma,37 males and 1 1 females,aged 40-65 years,ASA physical status Ⅰ or Ⅱ,were randomly divided into two groups.Patients in group T were given 0.375% ropivacaine 30 ml for incision infiltration before closing the abdomen and intrave-nous analgesia.Patients in group E were given 0.2% ropivacaine 100 ml for epidural analgesia. Pareoxib sodium 40 mg was injected intravenously 30 min toward the end of the operation.Pain scores were assessed by VAS at postoperative 2,6,12,24 and 48 h.Postoperative activity distance was re-corded on 1st,2nd,3th day after surgery;the time first getting off bed and hospital stay were recor-ded.Finally,the complications were also recorded.Results Compared with group T,VAS scores at rest and in activity 12,24 and 48 h postoperatively were significantly lower (P <0.05 ).Compared with group E,postoperative activity distance on 1st,2nd and 3th day after surgery in group T were shorter.Furthermore,the time first getting off bed and the hospital stay in group T were shorter than those in group E (P <0.05).The incidence of adverse reactions between the two groups had no sta-tistical significance.Conclusion The wound infiltration combined with intravenous analgesia is benefi-cial to early recovery and shorter hospital stay.
ABSTRACT
Objective To investigate the effects and mechanism of pre-treatment with an Nrf2 inducer dh404 on renal ischemia reperfusion injury in rats.Methods Thirty SD rats were divided into three groups using completely randomized digital table,dh404 was dissolved in sesame oil and was given orally 1.5 mg/kg the night before procedures and 5 hours before procedures.Rats in group Sham received no treatment of ischemic reperfusion.In group IR and group dh404,the renal ischemia reper-fusion (IR)model was established,24 hours after IR,the levels of serum creatininc (Cr)and urea ni-trogen (BUN),the activities of superoxide dismutase (SOD)and the content of malonaldehyde (MDA)in serum were measured,and hematoxylin eosin(HE)staining observe the changes in renal structure,the levels of γ-glutamate-cysteine ligase catalytic (GCLC)and modifier (GCLM)subunit, the expression of NF-κB,COX-2 and eNOS were measured.Results Compared with group Sham,the values of Cr,BUN in group IR and group dh404 were significantly higher (P <0.05).Compared to the group IR,the group dh404 Cr,BUN values significantly decreased after reperfusion for 24 h(P <0.05 ).Compared to group Sham,group IR SOD activity decreased,while the value of MDA increased(P <0.05 ).Compared to group IR,group dh404 had much higher SOD activity,while the value of MDA significantly decreased.Observed with optical microscopy,compared to group Sham, the renal tubular injury of group IR was obvious.Compared to group IR,group dh404 significantly reduced tubular injury.Compared to group IR,the levels of GCLC and modifier GCLM subunit were higher,while there were no significant differences of levels among NF-κB,COX-2 and eNOS. Conclusion Pre-treatment with an Nrf2 inducer dh404 can protect the kidney from IRI through possi-bly reducing IRI kidney oxidative stress.
