BACKGROUND: Acupuncture anesthesia was created in the 1950’s in China and continues to be used there today during most major surgeries. It is widely used in China for such complex operations as brain, heart, and abdominal surgery. It is popular in China because it is economical, practical, and beneficial to the patients. With acupuncture anesthesia there is less bleeding during surgery and there is also quicker post-operative recovery.OBJECTIVE: This randomized prospective study aims at comparing the effect of two acupoints(Yongquan, KI1 and Renzhong, DU26) with sham acupuncture and no acupuncture on the time to recovery of consciousness after general anesthesia by means of the Bispectral Index monitor(BIS).DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a prospective randomized controlled study. We randomly assigned 50 patients to 5 groups during recovery from surgical anesthesia. Four groups had acupuncture on KI1(group A), DU26(groups B), both KI1 and DU26(group C), and sham points(group D), and one had no acupuncture(group E).MAIN OUTCOME MEASURES: Bispectral Index(BIS), time to spontaneous eye opening, time to tracheal extubation, and time to following commands were measured as the main outcome measures.RESULTS: Time to spontaneous eye opening differed among groups(P=0.002), as well as time to tracheal extubation(P<0.000 1) and time to following commands(P=0.000 6). BIS values differed significantly among groups both 5 and 10 min after the end of anesthesia(P<0.000 1 and P=0.000 4,respectively). BIS values of groups D and E were lower than those of the other groups and those of group C were higher. The same pattern was observed also 15 and 30 min after the end of anesthesia, although the difference among groups was not significant at these time points(P=0.164 and P=0.104, respectively).CONCLUSION: Acupuncture on DU26 and KI1 accelerates recovery of consciousness after general anesthesia. Moreover, a possible synergistic effect of DU26 and KI1 is suggested. This issue may play a role in the optimization of operating room management and raise interest about the usefulness of acupuncture on unconsciousness states of different nature. 相似文献

Background Acute effects of physical exercise on the deformational behavior of knee articular cartilage and changes in cartilage volume are definite.However,conclusive effects of different exercises on the loss of articular cartilage volume have not been proved.In this parallel-group randomized controlled trial,we tested whether 12 weeks of swimming,powerstriding,cycling,and running exercises would decrease the cartilage volume significantly and whether there would be a difference in the loss of cartilage volume after different types of exercises.Methods From October 2012 to January 2013 we evaluated 120 healthy volunteer students in Biomechanics Laboratory of Tongji University.Body mass index (BMI),right lower limb strength,and right knee cartilage magnetic resonance imaging (MRI) were obtained before exercise.MRI were conducted in East Hospital.The study was approved by Tongji University Ethical Committee,all subjects were randomly assigned to the running,powerstriding,cycling,swimming,and control groups by a drawing of lots.Each group contained 24 samples.At the end of 12 weeks of regular exercises,the same measurement procedures were applied.Cartilage volume was calculated with OSIRIS software based on the quantitative-MRI.Pre-and post-exercise comparisons were carried out using paired t-tests and one-way analysis of variance (ANOVA) was used to compare differences of cartilage volume loss between groups with Student-Newman-Keuls procedure for multiple comparisons.Results Running,cycling,and swimming groups resulted in a significant decrease in BMI.The quadriceps peak torque increased significantly in the swimming and cycling groups.Total cartilage volume significantly decreased in the running and cycling groups after 12 weeks of training,without any significant change in the nonimpact swimming,low-impact powerstriding,and control groups.Loss of total cartilage volume in the running and cycling groups were 2.21% (3.03) and 1.50% (0.42).Conclusions Twelve weeks of regular physical exerc 相似文献

CONTEXT: Fabry disease is a metabolic disorder without a specific treatment, caused by a deficiency of the lysosomal enzyme alpha-galactosidase A (alpha-gal A). Most patients experience debilitating neuropathic pain and premature mortality because of renal failure, cardiovascular disease, or cerebrovascular disease. OBJECTIVE: To evaluate the safety and efficacy of intravenous alpha-gal A for Fabry disease. DESIGN AND SETTING: Double-blind placebo-controlled trial conducted from December 1998 to August 1999 at the Clinical Research Center of the National Institutes of Health. PATIENTS: Twenty-six hemizygous male patients, aged 18 years or older, with Fabry disease that was confirmed by alpha-gal A assay. INTERVENTION: A dosage of 0.2 mg/kg of alpha-gal A, administered intravenously every other week (12 doses total). MAIN OUTCOME MEASURE: Effect of therapy on neuropathic pain while without neuropathic pain medications measured by question 3 of the Brief Pain Inventory (BPI). RESULTS: Mean (SE) BPI neuropathic pain severity score declined from 6.2 (0.46) to 4.3 (0.73) in patients treated with alpha-gal A vs no significant change in the placebo group (P =.02). Pain-related quality of life declined from 3.2 (0.55) to 2.1 (0.56) for patients receiving alpha-gal A vs 4.8 (0.59) to 4.2 (0.74) for placebo (P =.05). In the kidney, glomeruli with mesangial widening decreased by a mean of 12.5% for patients receiving alpha-gal vs a 16.5% increase for placebo (P =.01). Mean inulin clearance decreased by 6.2 mL/min for patients receiving alpha-gal A vs 19.5 mL/min for placebo (P =.19). Mean creatinine clearance increased by 2.1 mL/min (0.4 mL/s) for patients receiving alpha-gal A vs a decrease of 16.1 mL/min (0.3 mL/s) for placebo (P =.02). In patients treated with alpha-gal A, there was an approximately 50% reduction in plasma glycosphingolipid levels, a significant improvement in cardiac conduction, and a significant increase in body weight. CONCLUSION: Intravenous infusions of alpha-gal A are safe and have widespread therapeutic efficacy in Fabry disease. 相似文献

Context Hip fractures are common in the elderly, and despite standard rehabilitation, many patients fail to regain their prefracture ambulatory or functional status. Objective To determine whether extended outpatient rehabilitation that includes progressive resistance training improves physical function and reduces disability compared with low-intensity home exercise among physically frail elderly patients with hip fracture. Design, Setting, and Patients Randomized controlled trial conducted between August 1998 and May 2003 among 90 community-dwelling women and men aged 65 years or older who had had surgical repair of a proximal femur fracture no more than 16 weeks prior and had completed standard physical therapy. Intervention Participants were randomly assigned to 6 months of either supervised physical therapy and exercise training (n = 46) or home exercise (control condition; n = 44). Main Outcome Measures Primary outcome measures were total scores on a modified Physical Performance Test (PPT), the Functional Status Questionnaire physical function subscale (FSQ), and activities of daily living scales. Secondary outcome measures were standardized measures of skeletal muscle strength, gait, balance, quality of life, and body composition. Participants were evaluated at baseline, 3 months, and 6 months. Results Changes over time in the PPT and FSQ scores favored the physical therapy group ( P = .003 and P = .01, respectively). Mean change (SD) in PPT score for physical therapy was +6.5 (5.5) points (95% confidence interval [CI], 4.6-8.3), and for the control condition was +2.5 (3.7) points (95% CI, 1.4-3.6 points). Mean change (SD) in FSQ score for physical therapy was +5.2 (5.4) points (95% CI, 3.5-6.9) and for the control condition was +2.9 (3.8) points (95% CI, 1.7-4.0). Physical therapy also had significantly greater improvements than the control condition in measures of muscle strength, walking speed, balance, and perceived health but not bone mineral density or fat-free mass. Conclusion In community-dwelling frail elderly patients with hip fracture, 6 months of extended outpatient rehabilitation that includes progressive resistance training can improve physical function and quality of life and reduce disability compared with low-intensity home exercise. 相似文献

Context Supplemental perioperative oxygen has been variously reported to halve or double the risk of surgical wound infection. Objective To test the hypothesis that supplemental oxygen reduces infection risk in patients following colorectal surgery. Design, Setting, and Patients A double-blind, randomized controlled trial of 300 patients aged 18 to 80 years who underwent elective colorectal surgery in 14 Spanish hospitals from March 1, 2003, to October 31, 2004. Wound infections were diagnosed by blinded investigators using Centers for Disease Control and Prevention criteria. Baseline patient characteristics, anesthetic treatment, and potential confounding factors were recorded. Interventions Patients were randomly assigned to either 30% or 80% fraction of inspired oxygen (FIO 2) intraoperatively and for 6 hours after surgery. Anesthetic treatment and antibiotic administration were standardized. Main Outcome Measures Any surgical site infection (SSI); secondary outcomes included return of bowel function and ability to tolerate solid food, ambulation, suture removal, and duration of hospitalization. Results A total of 143 patients received 30% perioperative oxygen and 148 received 80% perioperative oxygen. Surgical site infection occurred in 35 patients (24.4%) administered 30% FIO 2 and in 22 patients (14.9%) administered 80% FIO 2 ( P=.04). The risk of SSI was 39% lower in the 80% FIO 2 group (relative risk [RR], 0.61; 95% confidence interval [CI], 0.38-0.98) vs the 30% FIO 2 group. After adjustment for important covariates, the RR of infection in patients administered supplemental oxygen was 0.46 (95% CI, 0.22-0.95; P = .04). None of the secondary outcomes varied significantly between the 2 treatment groups. Conclusions Patients receiving supplemental inspired oxygen had a significant reduction in the risk of wound infection. Supplemental oxygen appears to be an effective intervention to reduce SSI in patients undergoing colon or rectal surgery. Trial Registration ClinicalTrials.gov Identifier: NCT00235456 相似文献

ObjectiveTo evaluate the effectiveness of acupuncture analgesia (AA) compared with combined spinal-epidural anesthesia (CSEA) for labor pain relief and labor outcomes.MethodsWe evaluated 131 primiparous women who received respiratory guidance during maternal uterine contractions and received either AA (n = 43), CSEA (n = 45), or no additional treatment (control, n = 43). The groups were compared regarding visual analog scale (VAS) scores for abdominal and back pain, and labor outcomes.ResultsThe abdominal VAS scores of the AA and CSEA groups were significantly lower than that of the control group. In addition, the VAS scores of the CSEA group were significantly lower than that of the AA group at 10 and 60 min after intervention. The back pain VAS scores of the AA and CSEA groups were significantly lower than that of the control group at 5, 10, and 60 min after intervention. The duration of the active phase of labor in the CSEA group was significantly longer than that of the AA and control groups. The rates of oxytocin use (4.70%), urinary retention (4.70%), and postpartum hemorrhage (273.72 ± 53.63 mL) in the AA group were significantly lower than in the CSEA group (46.70%, 24.20%, and 320.00 ± 85.60 mL, respectively).ConclusionBoth AA and CSEA were effective for labor pain relief, CSEA provided more effective pain relief, while AA was associated with a shorter duration of labor and fewer adverse effects.and each has its advantages and disadvantages. 相似文献

Context Hormone replacement therapy (HRT) and antioxidant vitamins are widely used for secondary prevention in postmenopausal women with coronary disease, but no clinical trials have demonstrated benefit to support their use. Objective To determine whether HRT or antioxidant vitamin supplements, alone or in combination, influence the progression of coronary artery disease in postmenopausal women, as measured by serial quantitative coronary angiography. Design, Setting, and Patients The Women's Angiographic Vitamin and Estrogen (WAVE) Trial, a randomized, double-blind trial of 423 postmenopausal women with at least one 15% to 75% coronary stenosis at baseline coronary angiography. The trial was conducted from July 1997 to January 2002 in 7 clinical centers in the United States and Canada. Interventions Patients were randomly assigned in a 2 x 2 factorial design to receive either 0.625 mg/d of conjugated equine estrogen (plus 2.5 mg/d of medroxyprogesterone acetate for women who had not had a hysterectomy), or matching placebo, and 400 IU of vitamin E twice daily plus 500 mg of vitamin C twice daily, or placebo. Main Outcome Measure Annualized mean (SD) change in minimum lumen diameter (MLD) from baseline to concluding angiogram of all qualifying coronary lesions averaged for each patient. Patients with intercurrent death or myocardial infarction (MI) were imputed the worst rank of angiographic outcome. Results The mean (SD) interval between angiograms was 2.8 (0.9) years. Coronary progression, measured in mean (SD) change, worsened with HRT by 0.047 (0.15) mm/y and by 0.024 (0.15) mm/y with HRT placebo ( P = .17); and for antioxidant vitamins by 0.044 (0.15) mm/y and with vitamin placebo by 0.028 (0.15) mm/y ( P = .32). When patients with intercurrent death or MI were included, the primary outcome showed an increased risk for women in the active HRT group ( P = .045), and suggested an increased risk in the active vitamin group ( P = .09). Fourteen patients died in the HRT group and 8 in the HRT placebo group (hazard ratio [HR], 1.8; 95% confidence interval [CI], 0.75-4.3), and 16 in the vitamin group and 6 in the vitamin placebo group (HR, 2.8; 95% CI, 1.1-7.2). Death, nonfatal MI, or stroke occurred in 26 HRT patients vs 15 HRT controls (HR, 1.9; 95% CI, 0.97-3.6) and in 26 vitamin patients and 18 vitamin controls (HR, 1.5; 95% CI, 0.80-2.9). There was no interaction between the 2 treatment interventions. Conclusion In postmenopausal women with coronary disease, neither HRT nor antioxidant vitamin supplements provide cardiovascular benefit. Instead, a potential for harm was suggested with each treatment. 相似文献

Context Low-income seniors frequently have multiple chronic medical conditions for which they often fail to receive the recommended standard of care. Objectives To test the effectiveness of a geriatric care management model on improving the quality of care for low-income seniors in primary care. Design, Setting, and Patients Controlled clinical trial of 951 adults 65 years or older with an annual income less than 200% of the federal poverty level, whose primary care physicians were randomized from January 2002 through August 2004 to participate in the intervention (474 patients) or usual care (477 patients) in community-based health centers. Intervention Patients received 2 years of home-based care management by a nurse practitioner and social worker who collaborated with the primary care physician and a geriatrics interdisciplinary team and were guided by 12 care protocols for common geriatric conditions. Main Outcome Measures The Medical Outcomes 36-Item Short-Form (SF-36) scales and summary measures; instrumental and basic activities of daily living (ADLs); and emergency department (ED) visits not resulting in hospitalization and hospitalizations. Results Intention-to-treat analysis revealed significant improvements for intervention patients compared with usual care at 24 months in 4 of 8 SF-36 scales: general health (0.2 vs –2.3, P = .045), vitality (2.6 vs –2.6, P < .001), social functioning (3.0 vs –2.3, P = .008), and mental health (3.6 vs –0.3, P = .001); and in the Mental Component Summary (2.1 vs –0.3, P < .001). No group differences were found for ADLs or death. The cumulative 2-year ED visit rate per 1000 was lower in the intervention group (1445 [n = 474] vs 1748 [n = 477], P = .03) but hospital admission rates per 1000 were not significantly different between groups (700 [n = 474] vs 740 [n = 477], P = .66). In a predefined group at high risk of hospitalization (comprising 112 intervention and 114 usual-care patients), ED visit and hospital admission rates were lower for intervention patients in the second year (848 [n = 106] vs 1314 [n = 105]; P = .03 and 396 [n = 106] vs 705 [n = 105]; P = .03, respectively). Conclusions Integrated and home-based geriatric care management resulted in improved quality of care and reduced acute care utilization among a high-risk group. Improvements in health-related quality of life were mixed and physical function outcomes did not differ between groups. Future studies are needed to determine whether more specific targeting will improve the program's effectiveness and whether reductions in acute care utilization will offset program costs.

BACKGROUND: The effectiveness of massage therapy for low-back pain has not been documented. This randomized controlled trial compared comprehensive massage therapy (soft-tissue manipulation, remedial exercise and posture education), 2 components of massage therapy and placebo in the treatment of subacute (between 1 week and 8 months) low-back pain. METHODS: Subjects with subacute low-back pain were randomly assigned to 1 of 4 groups: comprehensive massage therapy (n = 25), soft-tissue manipulation only (n = 25), remedial exercise with posture education only (n = 22) or a placebo of sham laser therapy (n = 26). Each subject received 6 treatments within approximately 1 month. Outcome measures obtained at baseline, after treatment and at 1-month follow-up consisted of the Roland Disability Questionnaire (RDQ), the McGill Pain Questionnaire (PPI and PRI), the State Anxiety Index and the Modified Schober test (lumbar range of motion). RESULTS: Of the 107 subjects who passed screening, 98 (92%) completed post-treatment tests and 91 (85%) completed follow-up tests. Statistically significant differences were noted after treatment and at follow-up. The comprehensive massage therapy group had improved function (mean RDQ score 1.54 v. 2.86-6.5, p < 0.001), less intense pain (mean PPI score 0.42 v. 1.18-1.75, p < 0.001) and a decrease in the quality of pain (mean PRI score 2.29 v. 4.55-7.71, p = 0.006) compared with the other 3 groups. Clinical significance was evident for the comprehensive massage therapy group and the soft-tissue manipulation group on the measure of function. At 1-month follow-up 63% of subjects in the comprehensive massage therapy group reported no pain as compared with 27% of the soft-tissue manipulation group, 14% of the remedial exercise group and 0% of the sham laser therapy group. INTERPRETATION: Patients with subacute low-back pain were shown to benefit from massage therapy, as regulated by the College of Massage Therapists of Ontario and delivered by experienced massage therapists. 相似文献

Context Pediatric obesity has escalated to epidemic proportions, leading to an array of comorbidities, including type 2 diabetes in youth. Since most overweight children become overweight adults, this chronic condition results in serious metabolic complications by early adulthood. To curtail this major health issue, effective pediatric interventions are essential. Objective To compare effects of a weight management program, Bright Bodies, on adiposity and metabolic complications of overweight children with a control group. Design One-year randomized controlled trial conducted May 2002-September 2005. Setting Recruitment and follow-up conducted at Yale Pediatric Obesity Clinic in New Haven, Conn, and intervention at nearby school. Participants Random sample of 209 overweight children (body mass index [BMI] >95th percentile for age and sex), ages 8 to 16 years of mixed ethnic groups were recruited. A total of 135 participants (60%) completed 6 months of study, 119 (53%) completed 12 months. Intervention Participants were randomly assigned to either a control or weight management group. The control group (n = 69) received traditional clinical weight management counseling every 6 months, and the weight management group (n = 105) received an intensive family-based program including exercise, nutrition, and behavior modification. Intervention occurred biweekly the first 6 months, bimonthly thereafter. The second randomization within the weight management group assigned participants (n = 35) to a structured meal plan approach (dieting), but this arm of the study was discontinued while enrollment was ongoing due to a high dropout rate. Main Outcome Measures Change in weight, BMI, body fat, and homeostasis model assessment of insulin resistance (HOMA-IR) at 6 and 12 months. Results Six-month improvements were sustained at 12 months in weight management vs control, including changes in the following (mean [95% confidence interval]): weight (+0.3 kg [1.4 to 2.0] vs +7.7 kg [5.3 to 10.0]); BMI (1.7 [2.3 to 1.1] vs +1.6 [0.8 to 2.3]); body fat (3.7 kg [5.4 to 2.1] vs +5.5 kg [3.2 to 7.8]); and HOMA-IR (1.52 [1.93 to 1.01] vs +0.90 [0.07 to 2.05]). Conclusion The Bright Bodies weight management program had beneficial effects on body composition and insulin resistance in overweight children that were sustained up to 12 months.

Background Venous thromboembolism (VTE) is an important complication after major orthopedic surgery.Pharmaceutical methods represent the main strategy of VTE prevention.The use of aspirin in VTE prevention is still controversial worldwide,especially in China.The purpose of this study was to evaluate the role of aspirin combined with mechanical measures in the prevention of VTE after total knee arthroplasty (TKA).Methods Between January 2012 and May 2013 and in accordance with the inclusion criteria,120 patients undergoing TKA were randomly allocated to two groups.To prevent VTE,patients in group A received aspirin combined with mechanical measures postoperatively,while patients in group B received low-molecular-weight heparin (LMWH) sodium and rivaroxaban sequentially in combination with mechanical measures postoperatively.All surgeries were performed by one surgeon using a posterior-stabilized cemented prosthesis.The two groups were followed up and compared for the incidence of deep vein thrombosis (DVT) by duplex ultrasound scan and clinical VTE events.The adverse events,the blood loss index,and the cost of VTE prevention were also compared.Results DVT was detected in 10 of 60 patients in group A (16.7%,95% CI:7.3%-26.1%) compared with 11 of 60 in group B (18.3%,95% CI:8.5%-27.8%) (P=0.500).There is no statistical evidence supporting the inferior effect of aspirin in preventing DVT as compared with the other medications.There were no cases of symptomatic VTE or death during the follow-up period.Area of ecchymosis was lower in group A than in group B,and the differences were statistically significant.Patients in group A had the lower blood loss index as compared with patients in group B.No transfusion cases were found in both groups.The differences were statistically significant.The cost of VTE prevention analysis indicated a cost reduction using aspirin in group A compared with using LMWH and rivaroxaban in group B.Conclusion Aspirin combined with mechanical measu 相似文献

Context Despite anecdotal reports, rigorous scientific evidence of the effectiveness of magnetic insoles for the pain of plantar fasciitis is lacking. Objective To determine whether magnetic insoles provide greater subjective improvement for treatment of plantar heel pain compared with identical nonmagnetized insoles. Design, Setting, and Participants Randomized, double-blind, placebo-controlled trial conducted from February 12, 2001, to November 9, 2001, of a volunteer sample of 101 adults with diagnoses of plantar heel pain for at least 30 days from a multispecialty group practice clinic in Rochester, Minn. Daily pain diaries were kept for 8 weeks. Interventions Cushioned insoles, with either active bipolar magnets or sham magnets, which were worn daily by the participants for 8 weeks. Main Outcome Measures Reported average daily foot pain (by metered visual analog scale [VAS] and by categorical response of change from baseline) at 4 and 8 weeks, and impact of insoles on employment performance and enjoyment. Results No significant between-group differences were found on any outcome variables studied when comparing active vs sham magnets. Both the nonmagnetic and magnetic groups reported significant improvements in morning foot pain intensity, with mean (SD) VAS scores improving from 6.9 (2.3) and 6.7 (2.0), respectively, at baseline to 3.9 (2.6) for each group at 8 weeks ( P = .94). At 8 weeks, 33% of the nonmagnetic group and 35% of the magnetic group reported being all or mostly better ( P = .78). At baseline, foot pain interfered moderately with participants' employment enjoyment (mean VAS, 4.2) and improved in both groups by 8 weeks (1.3 and 1.5, respectively; P = .68). Conclusion Static bipolar magnets embedded in cushioned shoe insoles do not provide additional benefit for subjective plantar heel pain reduction when compared with nonmagnetic insoles. 相似文献
