| 1 | Perioperative pain control after total knee arthroplasty: An evidence based review of the role of peripheral nerve blocks显示文摘Over the last decades,the number of total knee arthroplasty procedures performed in the United States has been increasing dramatically.This very successful intervention,however,is associated with significant postoperative pain,and adequate postoperative analgesia is mandatory in order to allow for successful rehabilitation and recovery.The use of regional anesthesia and peripheral nerve blocks has facilitated and improved this goal.Many different approaches and techniques for peripheral nerve blockades,either landmark or,more recently,ultrasound guided have been described over the last decades.This includes but is not restricted to techniques discussed in this review.The introduction of ultrasound has improved many approaches to peripheral nerves either in success rate and/or time to block.Moreover,ultrasound has enhanced the safety of peripheral nerve blocks due to immediate needle visualization and as consequence needle guidance during the block.In contrast to patient controlled analgesia using opioids,patients with a regional anesthetic technique suffer from fewer adverse events and show higher patient satisfaction;this is important as hospital rank-ings and advertisement have become more common worldwide and many patients use these factors in order to choose a certain institution for a specific procedure.This review provides a short overview of currently used regional anesthetic and analgesic techniques focusing on related implications,considerations and outcomes. | Thomas Danninger Mathias Opperer Stavros G Memtsoudis | 2014 | World Journal of Orthopedics2014，5，3： | 20 |
| 2 | Perioperative outcomes and type of anesthesia in hip surgical patients: An evidence based review显示文摘Over the last decades the demand for hip surgery,be it elective or in a traumatic setting,has greatly increased and is projected to expand even further.Concurrent with demographic changes the affected population is burdened by an increase in average comorbidity and serious complications.It has been suggested that the choice of anesthesia not only affects the surgery setting but also the perioperative outcome as a whole.Therefore different approaches and anesthetic techniques have been developed to offer individual anesthetic and analgesic care to hip surgery patients.Recent studies on comparative effectiveness utilizing population based data have given us a novel insight on anesthetic practice and outcome,showing favorable results in the usage of regional vs general anesthesia.In this review we aim to give an overview of anesthetic techniques in use for hip surgery and their impact on perioperative outcome.While there still remains a scarcity of data investigating perioperative outcomes and anesthesia,most studies concur on a positive outcome in overall mortality,thromboembolic events,blood loss and transfusion requirements when comparing regional to gener-al anesthesia.Much of the currently available evidence suggests that a comprehensive medical approach with emphasis on regional anesthesia can prove beneficial to patients and the health care system. | Mathias Opperer Thomas Danninger Ottokar Stundner Stavros G Memtsoudis | 2014 | World Journal of Orthopedics2014，5，3： | 17 |
| 3 | Correlation analysis of dual-energy CT iodine maps with quantitative pulmonary perfusion MRI显示文摘AIM:To correlate dual-energy computed tomography(DECT) pulmonary angiography derived iodine maps with parameter maps of quantitative pulmonary perfusion magnetic resonance imaging(MRI).METHODS:Eighteen patients with pulmonary perfusion defects detected on DECT derived iodine maps were included in this prospective study and additionally underwent time-resolved contrast-enhanced pulmonary MRI [dynamic contrast enhanced(DCE)-MRI].DCE-MRI data were quantitatively analyzed using a pixel-by-pixel deconvolution analysis calculating regional pulmonary blood flow(PBF),pulmonary blood volume(PBV) and mean transit time(MTT) in visually normal lung parenchyma and perfusion defects.Perfusion parameterswere correlated to mean attenuation values of normal lung and perfusion defects on DECT iodine maps.Two readers rated the concordance of perfusion defects in a visual analysis using a 5-point Likert-scale(1 = no correlation,5 = excellent correlation).RESULTS:In visually normal pulmonary tissue mean DECT and MRI values were:22.6 ± 8.3 Hounsfield units(HU);PBF:58.8 ± 36.0 mL/100 mL per minute;PBV:16.6 ± 8.5 mL;MTT:17.1 ± 10.3 s.In areas with restricted perfusion mean DECT and MRI values were:4.0 ± 3.9 HU;PBF:10.3 ± 5.5 mL/100 mL per minute,PBV:5 ± 4 mL,MTT:21.6 ± 14.0 s.The differences between visually normal parenchyma and areas of restricted perfusion were statistically significant for PBF,PBV and DECT(P < 0.0001).No linear correlation was found between MRI perfusion parameters and attenuation values of DECT iodine maps(PBF:r = 0.35,P = 0.15;PBV:r = 0.34,P = 0.16;MTT:r = 0.41,P = 0.08).Visual analysis revealed a moderate correlation between perfusion defects on DECT iodine maps and the parameter maps of DCE-MRI(mean score 3.6,k 0.45).CONCLUSION:There is a moderate visual but not statistically significant correlation between DECT iodine maps and perfusion parameter maps of DCE-MRI. | Jan Hansmann Paul Apfaltrer Frank G Zoellner Thomas Henzler Mathias Meyer Gerald Weisser Stefan O Schoenberg Ulrike I Attenberger | 2013 | World Journal of Radiology2013，5，5： | 6 |
| 4 | Six-minute walking test performance is associated with survival in cirrhotic patients显示文摘BACKGROUND Patients with cirrhosis are at risk of cirrhotic cardiomyopathy,with resulting cardiac dysfunction and exercise limitations.Six minute walking test(6MWT)assesses functional status and predicts morbidity and mortality in cardiopulmonary diseases.AIM To determine if it associates with mortality by analyzing 6MWT performance in patients with liver cirrhosis.METHODS A cohort of 106 cirrhotic patients was evaluated in the outpatient setting with echocardiogram and 6MWT and follow up for one year to document hepatic decompensation and mortality.The distance in meters was recorded at the end of 6 min(6MWD).RESULTS This cohort had a mean age of 51 years and 56%male;patients were staged as Child A in 21.7%,B 66%and C 12.3%.Walk distance inversely correlated with Child scores,and was significantly reduced as Child stages progresses.Patients who died(10.4%)showed shorter mean 6MWD(P=0.006).Low 6MWD was an independent predictor of mortality(P=0.01).CONCLUSION 6MWT is a noninvasive inexpensive test whose result is related to Child scores and mortality.It is useful to identify patients with liver cirrhosis at high risk of mortality for closer monitoring and potential early intervention. | Carolina Frade M G Pimentel Ana Cristina de Castro Amaral Adriano Miziara Gonzalez Michelle Lai Danielde Oliveira Mota Maria Lucia Gomes Ferraz Wilson Mathias Junior Mario Kondo | 2021 | World Journal of Hepatology2021，13，11： | 2 |
