ObjectivesTo systematically review the efficacy and safety of controlled hypotension for total hip or knee replacement.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on controlled hypotension for total hip or knee replacement from inception to September 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 15 RCTs involving 854 patients were included. The results of meta-analysis showed that compared with no controlled hypotension during surgery, controlled hypotension could reduce intraoperative blood loss (MD=?267.35, 95%CI ?314.54 to ?220.16, P<0.000 01), allogeneic blood transfusion (MD=?292.84, 95%CI ?384.95 to ?200.73, P<0.000 01), and 24 h postoperative mini-mental state examination (MMSE) score (MD=?1.08, 95%CI ?1.82 to ?0.34, P=0.004). However, there were no significant differences in 96 h postoperative MMSE score (MD=?0.11, 95%CI ?0.50 to 0.28, P= 0.57) and intraoperative urine volume (MD=57.93, 95%CI ?152.57 to 268.44, P=0.59).ConclusionsThe current evidence shows that controlled hypotension during total hip or knee replacement can reduce intraoperative blood loss and allogeneic blood transfusion. Furthermore, there is no obvious effect on the maintenance of blood perfusion in important organs, despite certain effects on the postoperative cognitive function, which can be recovered in short term. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
呼吸道感染在感染性疾病中占有重要地位，細菌性肺炎是呼吸道感染中的主要代表性疾病，最重要的治療措施是抗菌治療，用藥選擇及方法正確與否直接影響治療的成敗。同時如何降低醫療費用也是臨床醫生需要考慮的棘手問題。據國外文獻報道在英國每年約有5億張以上的抗微生物藥物處方，其中住院處方中約40％為靜脈制劑，而我國住院靜脈制劑的處方比例則更高。醫療費用的增加部分與靜脈用藥過多有關。為尋求解決臨床治療與醫療費用之間的矛盾，選擇高效、低毒、廉價的抗菌藥物，1987年Quintiliani等[1]首先提出了抗生素序貫療法（sequential therapy）的概念，即在經過相對短療程（48～72 h）靜脈抗菌藥物治療，臨床癥狀基本穩定或改善后，改為口服抗菌藥物治療。口服的抗菌藥物可以是與前者完全相同的口服劑型，也可以是同一類或抗菌譜相似的同一級藥物，后也有人稱之為"轉換治療"（switch therapy）、"降級治療"（step-down therapy）。據國外文獻報道，住院的社區獲得性肺炎（CAP）應用序貫療法者因早期出院每位患者節約費用293~1393美元[2-4]。
As a novel analgesic method, erector spinae plane block is increasingly widely used during perioperative period. This technique mainly injects local anesthetic drugs into the connective tissue between the deep fascia of the erector muscle and the transverse process of the vertebral body to achieve a blocking effect. Its role in postoperative analgesia in adult patients has been verified. Currently, case reports have shown that it also has a certain analgesic effect in pediatric patients, which can reduce postoperative pain scores and opioid consumption. Therefore, this article explores the application of erector spinae plane block in pediatric patients from various aspects, summarizes existing research results, and aims to provide more evidence for clinicians to reasonably use this block technique in the pediatric population.

There is a close relationship between inflammation and coagulation response. Inflammation and coagulation are activated simultaneously during cardiopulmonary bypass, which induce postperfusion syndrome. Leukocyte depletion filter can inhibit inflammation by reducing neutrophils in circulation. But, its effects on blood conservation are limited. Aprotinin is a serine protease inhibitor, and can prevent postoperative bleeding by anti-fibrinolysis and protection of platelet function. But its effects on anti-inflammation and protection of organs are subjected to be doubted. The combination of leukocyte depletion filter and aprotinin can inhibit inflammation as well as regulate coagulation, and may exert a good protective action during cardiopulmonary bypass.

Objective To evaluate the sedative effects of fentanyl on ventilated patients in intensive care unit (ICU ).Methods Thirty orotracheal intubated and mechanical ventilated medical patients in ICU were randomly divided into two groups，ie.Midazolam group (group M) and midazolam combined with fentanyl group with a proportion of 100∶1 (group M+F) The sedatives were continuously intravenously infused to achieve a target motor activity assessment scale (MAAS) of 3 and ventilator synchrony score of adaptation to the intensive care environment (ATICE) ≥3 after loading dose of midazolam.The sedation level was evaluated and the infusion rate was adjusted to maintain the target sedation goal every 2 h and the hemodynamic，respiratory and sedative parameters were recorded simultaneously.The oxygenation index were measured at 12 and 24 h.The infusion were ceased after 24 h,then the sedative degree was assessed every 30 min until MAAS ≥3 and the recover time were recorded.Results There were no significant differences in blood pressure，oxygenation index and adjustive frequency of drugs between the two groups (all Pgt;0.05).The heart rate，respiratory rate and airway pressure in group M+F decreased significantly than those in Group M (Plt;0.05).The amount of midazolam used and cost of sedatives were lower than those in group M (Plt;0.05).Satisfactory degree of sedation or ventilator synchrony and awakeness score of ATICE in group M+F were higher than those in group M.The recover time was shorter in groupM+F (Plt;0.05).Conclusion In medical ventilated patients, fentanyl improves the sedative effect of midazolam and reduces the dose of midazolam,hence,reduce the total cost of sedatives.
ObjectiveTo recognize the intraoperative recognition of parathyroid gland optical technology and explore its application value in thyroid surgery to protect the parathyroid gland.MethodsLiterature review was conducted on the principle and application status of intraoperative recognition of parathyroid gland optical technology by using " thyroidectomy” " parathyroid gland” " Near-Infrared imaging” " laser speckle contrast imaging”, and " optical coherence tomography” as retrieval terms to retrieve literatures.ResultsIntraoperative optical technique alone or in combination with contrast agent could improve the recognition rate of parathyroid gland, reduce the damage of feeding vessels, and thus reduce the incidence of postoperative hypocalcemia.ConclusionsTraditional intraoperative parathyroid gland recognition methods needs to be improved in real-time protection effectiveness and accuracy, and the combination of new optical technology and contrast agent can largely make up for these shortcomings, but there are still obstacles in the promotion.
ObjectiveTo explore the technique of preoperative evaluation of video electroencephalography (VEEG) electrode fixation method.MethodsThe electrode fixation method was modified using a simple and easy-to-manufacture 3M decompression sticker designed by ourselves.ResultsUsing the modified electrode fixation method, compared with the traditional fixation method, the electrode displacement, shedding rate and pain score of the children were significantly lower (P<0.05). The incidence of skin pressure sore by traditional fixation method was 7.03%. The rate of improvement after release was 3.37%. Although it was not statistically significant, the incidence of pressure ulcers were reduced.ConclusionsEffectively reduce the adverse reactions such as electrode displacement, shedding, pain and skin pressure sore caused by wearing the electrode for a long time. It has the advantages of being simple, fast, safe, stable and humanized, and it is worthy of clinical promotion.
Objective Isoflurane has an acute preconditioning effectiveness against ischemia in kidney, but this beneficial effectiveness can only last for 2-3 hours. To investigate whether isoflurane produces delayed preconditioningagainst renal ischemia/reperfusion (I/R) injury, and whether this process is mediated by hypoxia inducible factor 1α(HIF- 1α). Methods A total of 52 male C57BL/6 mice were randomly assigned to 4 groups (n=13 in each group): the controlgroup (group A), PBS/isoflurane treated group (group B), scrambled small interference RNA (siRNA)/isoflurane treated group (group C), and HIF-1α siRNA/isoflurane treated group (group D). In groups C and D, 1 mL RNase-free PBS containing 50 μg scrambled siRNA or HIF-1α siRNA was administered via tail vein 24 hours before gas exposure, respectively. Equivalent RNasefree PBS was given in groups A and B. Then the mice in groups B, C, and D were exposed to 1.5% isoflurne and 25%O2 for 2 hours; while the mice in group A received 25%O2 for 2 hours. After 24 hours, 5 mice in each group were sacrificed to assesse the expressions of HIF-1α and erythropoietin (EPO) in renal cortex by Western blot. Renal I/R injury was induced with bilateral renal pedicle occlusion for 25 minutes followed by 24 hours reperfusion on the other 8 mice. At the end of reperfusion, the serum creatinine (SCr), the blood urea nitrogen (BUN), and the histological grading were measured. Results The expressions of HIF-1α and EPO in groups B and C were significantly higher than those in group A (P lt; 0.01). The concentrations of SCr and BUN in groups B and C were significantly lower than those in group A, as well as the scores of tubules (P lt; 0.01), and the injury of kidney was amel iorated noticeably in groups B and C. The expressions of HIF-1α and the concentrations of SCr and BUN in group D were significantly lower than those in group A (P lt; 0.01). Compared with groups B and C, the expression of HIF- 1α and EPO in group D decreased markedly (P lt; 0.01), the concentrations of SCr and BUN were increased obviously, as well asthe scores of tubules (P lt; 0.01), and the renal injury was aggratived significantly. Conclusion Isoflurane produces delayed preconditioning against renal I/R injury, and this beneficial effectiveness may be mediated by HIF-1α.
