ABSTRACT
Objective: To analyze the effects of different doses of flurbiprofen and other analgesic drugs on the postoperative analgesia in the Enhanced Recovery After Surgery (ERAS) . Methods: 98 patients with jaw cysts or multiple impact teeth were retrospectively analyzed. Patients were divided into 3 groups by the drug scheme: flurbiprofen 250 mg + 0. 9％ NS to 100 ml (group Ⅰ, n =32), sulfentanil 100 μg + azasetron 20 mg + 0. 9％ NS to 100 ml (group Ⅱ, n = 34), flurbiprofen 200 mg + sulfentanil 50 μg + azasetron 20 mg + 0. 9％ NS to 100 ml (group Ⅲ, n = 32) . Analgesic effects were evaluated at 3 h, 1 d and 2 d after surgery with Wong-Baker expression scale and numeric rating scale (NRS) . Questionnaire survey was also used to evaluate degree of satisfaction on analgesia. Results: Analgesia effective rate of group Ⅰ, Ⅱ and Ⅲ was 40. 62％, 67. 65％ and 68. 75％ respectively (P ＜0. 05) . Degree of satisfaction on analgesia of group Ⅰ, Ⅱ and Ⅲ was 71. 87％, 58. 82％ and 93. 75％ respectively (P ＜ 0. 05) .Conclusion: Flurbiprofen combined with sulfentanil has good analgesic effects and low side effects in the maxillofacial surgery of jaw cysts and multiple impact teeth.
ABSTRACT
Objective To compare the efficacy of oxycodone versus sufentanil for intravenous analgesia after radical resection of pulmonary carcinoma performed via video-assisted thoracoscope.Methods One hundred fifty-four patients of both sexes, aged 18-64 yr, with body mass index of 18-25 kg/m2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective radical resection of pulmonary carcinoma performed via video-assisted thoracoscope, were randomly divided into either sufentanil group (group S, n=76) or oxycodone group (group O, n =78) using a random number table.The 2 groups received combined intravenous-inhalational anesthesia.When postoperative visual analogue scale (VAS) score ≥ 4, sufentanil 5 μg or oxycodone 2 mg was injected intravenously, and the administration was repeated when necessary until VAS score ≤ 3.Patient-controlled intravenous analgesia (PCIA) was then used for postoperative analgesia (lasting for 48 h).PCIA solution contained tropisetron 20 mg and sufentanil 200 μg in 100 ml of normal saline in group S.PCIA solution contained tropisetron 20 mg and oxycodone 50 mg in 100 ml of normal saline in group O.The PCIA pump was set up to deliver a 2 ml bolus dose with a 10 min lockout interval and background infusion at a rate of 1 ml/h.VAS score was maintained ≤3.When VAS scores ≥4, morphine 10 mg injected intramuscularly was used as rescue analgesic.The requirement for rescue analgesic, level of patient's satisfaction with analgesia,and analgesia-related adverse events were recorded.Results The incidence of nausea and vomiting was significantly lower in group O than in group S (P＜0.05).There was no significant difference in the requirement for rescue analgesic, level of patient's satisfaction, and incidence of dizziness and over-sedation between the two groups (P＞0.05).No patients developed respiratory depression and pruritus in the two groups.Conclusion Compared with sufentanil, oxycodone can produce similar analgesic efficacy when used for PCIA after radical resection of pulmonary carcinoma performed via video-assisted thoracoscope, with lower incidence of nausea and vomiting.
ABSTRACT
Objective To investigate the efficacy and safety of the postoperative analgesia after thoracotomy with different patient-controlled intravenous analgesia (PCIA)medication.Methods One hundred and twenty ASA Ⅰ or Ⅱ patients scheduled for elective thoracic surgery were randomly di-vided into four groups according to different PCIA formula:group S received sufentanil 3 μg/kg;group SD received sufentanil 1.5 μg/kg plus dezocine 0.3 mg/kg;group SF received sufentanil 1.5μg/kg plus flurbiprofen axetil 3 mg/kg;group DF received dezocine 0.3 mg/kg plus flurbiprofen ax-etil 3 mg/kg.For all four goups,the applied medicine was diluted with 0.9% saline to 300 ml,and was infused at 5 ml/h with a bolus dose of 3 ml.The lockout time was set at 1 5 min.The VAS and Ramsay sedation scale were recorded 2,4,8,24,48 h after surgery,respectively.Total pressing times and the side effects were also recorded for the 24 h period after the surgery.Results There were no significant differences of the VAS score at the time 2,4,8,24 and 48 h post surgery of press num-bers within 24 h postoperatively among all groups.The Ramsay sedation scale was significantly high-er at the time 2,4,8,24 h after surgery in group S than those in other three groups (P <0.05).The side effects were more in group S than those in other three groups (P <0.05).Conclusion Compared with sufentanil alone,combination therapy is safer and more effective for analgesia after thoracic sur-gery.With good outcomes and less side effects,it deserves more consideration in clinics.
ABSTRACT
Objective To evaluate the effects of ischemic time factors on reduction of myocardial ischemia-reperfusion injury by sulfentanil postconditioning in rats .Methods Healthy adult male Sprague-Dawley rats ,weighing 230-250 g ,were heparinized and anesthetized with intraperitoneal 5% chloral hydrate 8 ml/kg .The hearts were excised and perfused in a Langendorff apparatus with K-H solution .After 30 min of stabilization ,48 isolated rat hearts were randomly assigned into 6 groups (n=8 each) using a random number table .In I/R1-3 groups ,the hearts were subjected to 30 ,45 ,and 60 min of myocardial ischemia ,respectively ,followed by 90 min of reperfusion . In SP1-3 groups , the hearts were subjected to 30 , 45 , and 60 min of myocardial ischemia , respectively ,followed by 90 min of reperfusion ,and sulfentanil 100 nmol/L was added to K-H solution at 15 min of reperfusion for postconditioning . Left ventricular end-diastolic pressure (LVEDP ) , left ventricular developed pressure (LVDP) ,+dp/dtmax ,-dp/dtmax ,HR and coronary flow (CF) were measured at the end of equilibration and 15 ,30 ,60 and 90 min of reperfusion .Creatine kinase (CK) and lactate dehydrogenase (LDH) activities in coronary effluent were measured at 5 min of reperfusion .Myocardial infarct size was determined in 5 hearts chosen randomly at 90 min of reperfusion .Results LVEDP was significantly higher ,and LVDP , ± dp/dtmax and CF were lower at each time point of reperfusion than at the end of equilibration in I/R1-3 groups ( P0.05 ) .Conclusion Sulfentanil postconditioning can attenuate myocardial ischemia-reperfusion injury when the rats are subjected to 30 or 45 min of ischemia ,however ,it provides no myocardial protection when the rats are subjected to 60 min of ischemia .
ABSTRACT
Objective To observe the anaesthetic effect of sulfentanil combined with bupivacaine for subarachnoid block on cesarean section patients and the influence on the patient and fetus.Methods Eighty patients who were scheduled for elective cesarean section under subarachnoid block,were distributed into two groups:bupivacaine with no sulfenlanil(group B)and bupivacaine with sulfentanil(group BS).Detected SBP,DBP,MAP,HR,SpO2 before and after anesthesia.The time of drug onset,motor recovery and pain recovery were recorded,the effect of muscle relaxation was evaluated,and the drag reaction,neonatal Apgar score and anesthesia complication were recorded.Results There was no significant difference in the time of drug onset and motor recovery,muscle relaxation,neonatal Apgar score between the two groups.MAP was lower after 3-10 min of anesthesia than before anesthesia,but there was no significant difference after 30-120 min of anesthesia in the two groups.The rate of drag reaction was 27.5% in group B,but no case in group BS.The time of pain recovery was longer in group BS than that in group B(P＜0.01).The rate of temporary itch of skin after operation was 17.5% in group BS.Conclusion The addition of sulfentanil to hyperbaric bupivacaine provides adequate anesthesia for cesarean section and good postoperative analgesia.
ABSTRACT
Objective To investigate the effects of pretreatment with different concentrations of sufentanil of ketamine on the differentiation of human helper T cells in vitro. Methods Twenty-two healthy volunteers (11 males, 11 females) aged 20-45 yrs were enrolled in this study. In each volunteer 20 ml of blood was taken from peripheral vein and divided into 7 groups: control group (0.9% NaCl), 3 sufentanil groups (0.05, 0.5, 5.0 ng?ml-1) and 3 ketamine groups (100, 500, 2 500 ng?ml-1) .Whole blood and mononuclear cells from peripheral blood (PBMCs) were incubated in the presence of 0.9% NaCl or different concentrations of sufentanil or ketamine for 24 h. Then the stimulants-phorbolmyristate + lonomycin + glgistap (inhibitor of intracellular protein transport) were added to whole blood and phytohemagglutinin (PHA) was add to PBMCs. The whole blood was incubated for another 4h and PBMCs were incubated for another 48 h. Then the T-lymphocytes were collected for determination of intracellular level of IFN-?(as a marker of Th1 cells) and IL-4 (as a marker of Th2 cells) in the whole blood using three-color flow cytometry and the expression of CCR5 + (as a marker of Th1 cells) and CCR3 + (as a marker of Th2 cells) in PBMCs. The Th1/Th2 ratio was calculated. Results In sufentanil 0.5 and 5.0 ng?ml-1 groups the percentage of Th2 cells was significantly increased while the percentage of Th1 cells and Th1/Th2 ratio were significantly decreased. In ketamine 500 and 2 500 ng?ml-1 groups the percentage of both Th1 and Th2 cells were significantly decreased and the Th1/Th2 ratio was significantly increased. Conclusion Sufentanil can encourage helper cells to differentiate into Th2 cells while ketamine inhibit the helper cells to differentiate into Th1 and Th2 cells, especially the Th2 cells in a dose-dependent manner.
