The Efficacy and Safety of Regional Nerve Blocks in Total Hip Arthroplasty: Systematic Review and Direct Meta-Analysis

BackgroundRegional nerve blocks may be used as a component of a multimodal analgesic protocol to manage postoperative pain after primary total hip arthroplasty (THA). The purpose of our study was to evaluate the efficacy and safety of regional nerve blocks after THA in support of the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Management.MethodsWe searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials for studies published prior to March 24, 2020 on fascia iliaca, lumbar plexus, and quadratus lumborum blocks in primary THA. All included studies underwent qualitative and quantitative homogeneity testing followed by a systematic review and direct comparison meta-analysis to assess the efficacy and safety of the regional nerve blocks.ResultsAn initial critical appraisal of 3,382 publications yielded 11 publications representing the best available evidence for an analysis. Fascia iliaca, lumbar plexus, and quadratus lumborum blocks demonstrate the ability to reduce postoperative pain and opioid consumption. Among the available comparisons, no difference was noted between a regional nerve block or local periarticular anesthetic infiltration regarding postoperative pain and opioid consumption.ConclusionLocal periarticular anesthetic infiltration should be considered prior to a regional nerve block due to concerns over the safety and cost of regional nerve blocks. If a regional nerve block is used in primary THA, a fascia iliaca block is preferred over other blocks due to the differences in technical demands and risks associated with the alternative regional nerve blocks.

去势比格犬腹部脂肪与相关血清学指标及骨密度的变化关系

目的通过建立去势比格犬模型,观察绝经早期腹部脂肪变化规律,并通过对脂肪与骨代谢相关血清学指标的测量与分析,探讨脂肪及骨代谢的关键影响因素。方法选取6只成年雌性比格犬进行去势术,分别在术前、术后4个月、6个月、10个月进行腰椎定量CT(quantatitive computed tomography,QCT)腹部脂肪面积、骨密度(bone mineral density,BMD)、MRI腰椎骨髓脂肪含量及血清学指标的检测,比较不同时间各指标的变化趋势及关系。结果比格犬腹内脂肪面积(visceral fat area,VFA)、皮下脂肪面积(subcutaneous fat area,SFA)、腹部总脂肪面积(total fat area,TFA)在术后6个月、10个月均增加(P0.05),术后10个月VFA增加百分比均值为84.39%,且为三者中最大;术后比格犬BMD并未明显降低。体重、BMD、瘦素(leptin,LP)、VFA、高密度脂蛋白(high-density lipoprotein,HDL)与SFA相关。SFA、体重、低密度脂蛋白(low-density lipoprotein,LDL)、内脏脂肪素(visfatin,VFN)与BMD相关。结论去势比格犬模型可用于研究绝经后雌激素缺乏所引起的脂肪代谢变化,但短期内BMD并未明显丢失,骨、脂肪代谢之间存在交互作用。     

Outcomes after occupational therapy intervention for traumatic brachial plexus injury: A prospective longitudinal cohort study

Study DesignProspective longitudinal cohort study.IntroductionTraumatic brachial plexus injuries (BPIs) can be devastating and negatively impact daily function and quality of life. Occupational therapists play an important role in rehabilitation; however, studies identifying outcomes are lacking.PurposeThis study aims to describe outcomes including motor recovery, upper limb function, participation, pain, and quality of life for people receiving occupational therapy intervention.MethodsA convenience sample of English-speaking adults (n = 30) with a traumatic BPI, attending the clinic between December 1, 2014, to November 30, 2016, participated. Participants received occupational therapy focusing on sensorimotor retraining and activity-based rehabilitation. Data on active range of motion (goniometry), strength (Medical Research Council (MRC)), upper-limb function (UEFI15, QuickDASH), participation (PSFS), pain (Brief Pain Inventory), and quality of life (EQ-5D-3L) were collected at baseline, 3, 6, 9, and 12 months.ResultsElbow flexion strength showed significant improvement at all time-points, average increase 2.17 (MRC) (95% confidence interval: 1.29-3.04; P < .001) and mean final MRC grading 3.86 (standard error: 0.44). Significant improvements at 12 months were seen in: shoulder abduction strength and range, flexion strength and range, external rotation range; elbow extension strength and flexion range; thumb flexion and extension strength. Upper limb function (QuickDASH) showed significant improvement (mean change = 18.85; 95% confidence interval: 4.12-33.59; P = .02). Forearm protonation range and finger flexion strength were significantly worse. Remaining outcomes did not show significant improvement.ConclusionsOccupational therapy with surgical intervention can improve strength, range, and upper limb function with people following traumatic BPI. Further investigations into impact on participation, pain, and quality of life are required.     

Dexamethasone as an adjuvant for peripheral nerve blockade: a randomised,triple-blinded crossover study in volunteers

Background

The efficacy of dexamethasone in extending the duration of local anaesthetic block is uncertain. In a randomised controlled triple blind crossover study in volunteers, we tested the hypothesis that neither i.v. nor perineurally administered dexamethasone prolongs the sensory block achieved with ropivacaine.

持续质量改进在体检科护理质量管理中的应用效果探讨

目的探究持续质量改进在体检科护理质量管理中的应用效果。方法该次将该院在2018年7-12月的体检者200名作为研究的对象,视为对照阶段,采取常规护理管理方法;将该院2019年1-6月的体检者200名作为观察阶段对象,在护理管理工作中采取持续质量改进管理模式,进一步对比两个阶段患者对于体检科工作质量的评分。结果在体检工作质量、服务态度、体检满意度这3个模块,观察阶段评分对照阶段比较均明显更高,差异有统计学意义(P<0.05)。结论持续质量改进应用于体检科护理质量管理中,可有效提升体检服务品质,值得推广应用。     

Bloqueo bilateral del grupo de nervios pericapsulares (PENG) como analgesia en cirugía de cadera infantil

Effective management and control of peri- and postoperative pain in hip surgery is essential in order to minimize the use of opioids and their adverse effects. Effective regional analgesia for hip pain is made particularly challenging by the complex innervation of the hip joint. Standard regional techniques can be associated with complications, including incomplete anesthesia, hypotension, or lower limb weakness. We present the case of a 5-year-old girl with a history of infantile cerebral palsy who underwent bilateral varus derotation osteotomy and adductor tenotomy due to paralytic dislocation. She received bilateral PENG block and femoral cutaneous nerve block - a simple technique that covers all the nerves involved in the sensory innervation of the joint capsule without the need for multiple injections.

Perioperative management of diabetes

Diabetes is a complex, chronic metabolic disorder affecting approximately 9.3% of the adult population with the estimated number of adults with diabetes worldwide having more than tripled since 2000. This increase has largely been attributed to global urbanization and lifestyle changes. Diabetes affects 10–15% of the surgical population. These patients are frequently elderly, have complex medical co-morbidities and present for both high-risk elective and emergency surgery. This multisystem disease poses a significant challenge to both anaesthesia and surgery with patients with diabetes demonstrating higher morbidity and mortality rates compared to their non-diabetic counterparts. It is crucial that good glycaemic control is maintained throughout the perioperative period as this has been shown to correlate with positive patient outcomes. It is well-recognized that a co-ordinated, multidisciplinary approach aimed at optimizing every point in the patient pathway from GP referral to post-discharge care is required to obtain the best outcomes for the surgical patient with diabetes. The anaesthetist has a key role in the perioperative diabetes multidisciplinary team. Patients themselves are well experienced in manging their own diabetes and should be involved in doing so whenever possible.
