Purpose:To study analgesia effect ,adverse reactions and life quality changes of transdermal fentanyl in patients with cancer pain.Methods:30 patients with moderate or severe cancer pain were treated by transdermal fentanyl .The pain intensity, quality of life and adverse reactions were observed before and after the treatment.Results:After using transdermal fentanyl ,all the patients obtained moderate to good remission.The excellent,marked and moderate rates were 43.33%,53.33% and 3.33% respectively. The adverse reactions included nausea, vomiting,constipation,dizziness and lethargy.The rate of the adverse reactions was less.The quality of life improved markedly. Conclusions:Transdermal fentanyl is a safe,effective and simple way to relieve cancer pain in patients with moderate or severe pain.It can improve the quality of life markedly.Its adverse reactions are mild.

Background and purpose:It is important to control acute pain after gynecological oncologic surgery effectively.This study was to compare the clinical effects of butorphanol and flurbiprofen axetil(FA) combined with sufentanil on patient controlled intravenous analgesia(PCIA) after surgery.Methods:Forty ASA Ⅰ-Ⅱ patients scheduled for elective gynecological oncologic surgery under general anesthesia were randomly divided into two groups of twenty each,butorphanol group(Group B) and flurbiprofen axetil(FA) combined with sufentanil group(Group FS).After induction Group B received a loading dose of butorphanol 1 mg,and Group FS received that of FA 50 mg.Before the operation was over,Group B received intravenous infusion of butorphanol 13 mg in 100 mL saline,whereas Group FS received that of FA 150 mg combined with sufentanil 200 ?g in 100 mL saline.In the postoperative period,visual analogue scale(VAS),Ramsay sedative scores and side effects were recorded at 6,12,24 and 48 h.Results:There were not any signifi cant differences in VAS and the demanding times for supplemental bolus between the two groups.All VAS were below 4.Ramsay sedative scores of Group B before 12 h were signifi cantly higher than those in group FS(P0.05).The incidence of nausea and vomiting in Group FS was signif icantly higher than that in Group B(P

Background and purpose: Preemptive analgesia is one of the strategies to treat postoperative pain by preventing the establishment of central sensitization. This study was designed to explore whether the method of flurbiprofen axetil injection combined with bilateral cervical plexus nerve block in thyroid carcinoma surgery as multimodal preemptive analgesia can serve as a better analgesia. Methods: Sixty patients with thyroid carcinoma were randomly divided into three groups. Patients in Group A were treated with flurbiprofen axetil injection combined with bilateral cervical plexus nerve block as multimodal preemptive analgesia. Patients in Group B were anesthetized with bilateral cervical plexus nerve block. General anesthesia alone was used in patients of Group C. The onset time of nerve block, operation time, extubation time and dosage of fentanyl were recorded. The VAS (visual analogue scale) was used to evaluate the pain level, the side effects of drugs were also analyzed. Results: The onset time of nerve block in Group A, Group B were (7.47±1.04) min and (8.75±1.36) min, repectively (P<0.05). The dosage of fentanyl n Group A, B and C were (0.36±0.04) mg, (0.40±0.06) mg and (0.45±0.07) mg, respectively (Group A vs Group B P<0.05; Group A vs Group C, P<0.01).VAS scores of patients in Group C were higher than both Group A and B at 4,8 h after operation. Moreover, patients in Group B got higher VAS scores than that of Group A at 8 h. The side effects of both Group A and B were much less serious than that of Group C. Conclusion: Flurbiprofen axetil injection combined with bilateral cervical plexus nerve block as multimodal preemptive analgesia during thyroid carcinoma surgery can supply better analgesia and opioid-sparing effects, with less side effects.

OBJECTIVE To study the effect of fluoropezil on embryo-fetal developmental toxicity and toxicokinetics in rabbits,and provide reference for clinical medication.METHODS According to the sequence of pregnancy,pregnant rabbits were divided into five groups:vehicle control group(1%hydroxy-propyl methylcellulose+1.5%polyethylene glycol 400 aqueous solution),positive control group(cyclo-phosphamide 18 mg·kg-1),and fluoropezil(3.6,9.0 and 22.5 mg·kg-1)groups.The vehicle control group and the fluoropezil groups were ig administrated on the 6th to 18th day of gestation(GD6-18)while the positive control group was ig given cyclophosphamide on GD6-20.The pregnant rabbits were sacri-ficed on GD28,and the embryo-fetal development was detected.Sex hormone levels of pregnant rabbits on GD5,GD18 and GD28 were detected by ELISA method.Blood samples with toxokinetics were collected for concomitant toxic generation at the first and last administration,and drug concentrations in fetal,placenta and amniotic fluid were detected with liquid chromatography tandem mass spectrometry(LC-MS/MS).RESULTS Fluoropezil 3.6,9.0 and 22.5 mg·kg-1 had no significant effect on body mass,mass gain,food consumption,pregnancy outcomes,fetal appearance,viscera,skeletal and physical growth and development of pregnant rabbits.Only on GD18 or GD28,the levels of follicle stimulating hormone,estra-diol and progesterone in each dose group fluctuated to some extent.The combined toxokinetics results indicated that fluoropezil could cross the placental barrier of the rabbits,but did not accumulate in preg-nant rabbits or fetuses.Fetal mass,crown-rump length and uterus mass in the cyclophosphamide group were lower than those in the vehicle control group.The appearance and bone of the cyclophos-phamide group were positive.CONCLUSION The no observed adverse effect level(NOAEL)of fluoro-pezil toxicity on rabbit embryo-fetal development is 22.5 mg·kg-1,which is 125 times of the effective dose.At the dosage level of 22.5 mg·kg-1,Cmax is 1093 μg·L-1,and AUC(0-24 h)6650 μg·h·L-1 on GD18.
