Abstract

PURPOSE Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) represents a minimally invasive technique of aortic occlusion (AO). It has been demonstrated to be safe and effective with appropriate training in traumatic hemorrhage with hemodynamic instability; however, its indications are still debated. The aim of this systematic review and meta-analysis is to assess the impact of REBOA on mortality in torso trauma patient with severe non-compressible hemorrhage compared to other temporizing hemostatic techniques. STUDY DESIGN The primary outcome is represented by 24-h, and in-hospital mortality. Secondary outcomes are post-procedural hemodynamic improvement (systolic blood pressure-SBP), mean injury severity score (ISS) differences, treatment-related morbidity, transfusional requirements and identification of prognostic factors. RESULTS A significant survival benefit at 24 h (RR 0.46; 95% CI 0.27-0.79; I(2): 55%; p = 0.005) was highlighted in patients undergoing REBOA. Regarding in-hospital mortality (RR 0.99; 95% CI 0.75-1.32; I(2): 73%; p = 0.98) no differences in risk of death were noticed. A hemodynamic improvement-although not significant-was highlighted, with 55.8 mmHg post-AO SBP mean difference between REBOA and control groups. A significantly lower mean number of packed Red Blood Cells (pRBCs) was noticed for REBOA patients (mean difference: - 3.02; 95% CI - 5.79 to - 0.25; p = 0.033). Nevertheless, an increased risk of post-procedural complications (RR 1.66; 95% CI 0.39-7.14; p = 0.496) was noticed in the REBOA group. CONCLUSIONS REBOA may represent a valid tool in the initial treatment of multiple sites subdiaphragmatic hemorrhage with refractory hemodynamic instability. However, due to several important limitations of the present study, our findings should be interpreted with caution. LEVEL OF EVIDENCE Level III according to ELIS (SR/MA with up to two negative criteria).

Abstract

BACKGROUND Pilonidal disease (PD) is a debilitating condition characterised by the infection of subcutaneous tissue in the sacrococcygeal area. It is associated with a high risk of recurrence, pain, infection, and purulent discharge. The two main surgical methods of pilonidal sinus disease include excision with primary closure/flap repair or excision of the sinus with healing by secondary intent. Wounds left open to heal by secondary intent remain extremely common due to their association with reduced risk of recurrence, however, it is associated with prolonged healing times. This study aims to determine whether platelet-rich plasma (PRP) reduces healing time in patients post pilonidal sinus surgery with healing by secondary intent compared to simple wound dressings. METHOD Six databases were searched from their date of origin to May 30, 2022 for randomised control trials using predetermined inclusion and exclusion criteria. Only four papers were selected for review as per the Population, Intervention, Comparison, Outcomes and Study design (PICOS) criteria. Critical appraisal was carried out according to the Scottish Intercollegiate Guidelines Network Methodology Checklist for Randomised Control Trials and was assessed for risk of bias according to the Cochrane Handbook for Systematic Review of Interventions. The pooled effect size was calculated using the fixed-effect model. A homogeneity of pooled effect size for the studies was also found (Cochrane Q test, p-value = 0.97 I-square = 0.0%). RESULT Four studies (n = 336) were included in this review. Three of the four studies reported a statistically significant reduction in time taken in healing the wound. The mean difference between the intervention (PRP group) and the control group was 13.01 days, (95% CI 12.15-13.86 days, p < 0.00001). All of the included studies also reported a statistically significant reduction in time taken to return to work/activities of daily living in the treatment group compared to the control group (MD 9.68 days, 95% CI 9.16-10.21 days, p < 0.00001). CONCLUSION This study shows that PRP is effective in reducing healing time and is associated with a significantly shorter period taken to return to work/activities of daily living in patients post pilonidal sinus surgery, which was the primary and secondary outcome investigated in this systematic review, respectively. PRP should routinely be offered to patients undergoing excisional pilonidal sinus surgery for the aforementioned benefits.

Abstract

INTRODUCTION extremity tourniquet (TQ) use has increased in the civilian setting; the beneficial results observed in the military has influenced acceptance by EMS and bystanders. This review aimed to analyze extremity TQ types used in the civilian setting, injury site, indications, and complications. METHODS a systematic review was conducted based on original articles published in PubMed, Embase, and Cochrane following PRISMA guidelines from 2010 to 2019. Data extraction focused on extremity TQ use for hemorrhage control in the civilian setting, demographic data, study type and duration, mechanism of injury, indications for use, injury site, TQ type, TQ time, and complications. RESULTS of the 1384 articles identified, 14 were selected for review with a total of 3912 civilian victims with extremity hemorrhage and 3522 extremity TQ placements analyzed. The majority of TQs were applied to male (79%) patients, with blunt or penetrating trauma. Among the indications for TQ use were hemorrhagic shock, suspicion of vascular injuries, continued bleeding, and partial or complete traumatic amputations. Upper extremity application was the most common TQ application site (56%), nearly all applied to a single extremity (99%), and only 0,6% required both upper and lower extremity applications. 80% of the applied TQs were commercial devices, and 20% improvised. CONCLUSIONS TQ use in the civilian setting is associated with trauma-related injuries. Most are single-site TQs applied for the most part to male adults with upper extremity injury. Commercial TQs are more commonly employed, time in an urban setting is under 1 hour, with few complications described.

Abstract

CONTEXT Amid extensive debate, evidence surrounding the use of platelet-rich plasma (PRP) for musculoskeletal injuries has rapidly proliferated, and an overall assessment of efficacy of PRP across orthopaedic indications is required. OBJECTIVES (1) Does PRP improve patient-reported pain in musculoskeletal conditions? and (2) Do PRP characteristics influence its treatment effect? DATA SOURCES MEDLINE, EMBASE, Cochrane, CINAHL, SPORTDiscus, and Web of Science libraries were searched through February 8, 2017. Additional studies were identified from reviews, trial registries, and recent conferences. STUDY SELECTION All English-language randomized trials comparing platelet-rich therapy with a control in patients 18 years or older with musculoskeletal bone, cartilage, or soft tissue injuries treated either conservatively or surgically were included. Substudies of previously reported trials or abstracts and conference proceedings that lacked sufficient information to generate estimates of effect for the primary outcome were excluded. STUDY DESIGN Systematic review and meta-analysis. LEVEL OF EVIDENCE Level 1. DATA EXTRACTION All data were reviewed and extracted independently by 3 reviewers. Agreement was high between reviewers with regard to included studies. RESULTS A total of 78 randomized controlled trials (5308 patients) were included. A standardized mean difference (SMD) of 0.5 was established as the minimum for a clinically significant reduction in pain. A reduction in pain was associated with PRP at 3 months (SMD, -0.34; 95% CI, -0.48 to -0.20) and sustained until 1 year (SMD, -0.60; 95% CI, -0.81 to -0.39). Low- to moderate-quality evidence supports a reduction in pain for lateral epicondylitis (SMD, -0.69; 95% CI, -1.15 to -0.23) and knee osteoarthritis (SMD, -0.91; 95% CI, -1.41 to -0.41) at 1 year. PRP characteristics did not influence results. CONCLUSION PRP leads to a reduction in pain; however, evidence for clinically significant efficacy is limited. Available evidence supports the use of PRP in the management of lateral epicondylitis as well as knee osteoarthritis.

Abstract

INTRODUCTION Administration of tranexamic acid (TXA) in coagulopathy of trauma gained popularity after the CRASH-2 trial. The aim of our analysis was to analyze the role of TXA in severely injured trauma patients with admission hyperfibrinolysis. METHODS We reviewed the prospectively collected Pragmatic, Randomized Optimal Platelet and Plasma Ratios database. We included patients with admission hyperfibrinolysis (Ly30 >3%) on thromboelastography. Patients were stratified into two groups (TXA and No-TXA) and were matched in 1:2 ratio using propensity score matching for demographics, admission vitals, and injury severity. Primary outcome measures were 6-, 12-, and 24-hour and 30-day mortality; 24-hour transfusion requirements; time to achieve hemostasis; and rebleeding after hemostasis requiring intervention. Secondary outcome measures were thrombotic complications. RESULTS We analyzed 680 patients. Of those, 118 had admission hyperfibrinolysis, and 93 patients (TXA: 31 patients; No-TXA: 62 patients) were matched. Matched groups were similar in age (p = 0.33), gender (p = 0.84), race (p = 0.81), emergency department (ED) Glasgow Coma Scale (p = 0.34), ED systolic blood pressure (p = 0.28), ED heart rate (p = 0.43), mechanism of injury (p = 0.45), head Abbreviated Injury Scale score (p = 0.68), injury severity score (p = 0.56), and blood products ratio (p = 0.44). Patients who received TXA had a lower 6-hour mortality rate (34% vs. 13%, p = 0.04) and higher 24-hour transfusion of plasma (15 vs. 10 units, p = 0.03) compared with the No-TXA group. However, there was no difference in 12-hour (p = 0.24), 24-hour (p = 0.25), and 30-day mortality (p = 0.82). Similarly, there was no difference in 24-hour transfusion of RBC (p = 0.11) or platelets (p = 0.13), time to achieve hemostasis (p = 0.65), rebleeding requiring intervention (p = 0.13), and thrombotic complications (p = 0.98). CONCLUSION Tranexamic acid was associated with increased 6-hour survival but does not improve long-term outcomes in severely injured trauma patients with hemorrhage who develop hyperfibrinolysis. Moreover, TXA administration was not associated with thrombotic complications. Further randomized clinical trials will identify the subset of trauma patients who may benefit from TXA. LEVEL OF EVIDENCE Therapeutic study, level III.

Abstract

BACKGROUND The role of tranexamic acid (TXA) in reducing blood loss following primary shoulder arthroplasty has been demonstrated in small retrospective and controlled clinical trials. This study comprehensively evaluates current literature on the efficacy of TXA to reduce perioperative blood loss and transfusion requirements following shoulder arthroplasty. METHODS PubMed, MEDLINE, CENTRAL, and Embase were searched from the database inception date through October 27, 2016, for all articles evaluating TXA in shoulder arthroplasty. Two reviewers independently screened articles for eligibility and extracted data for analysis. A methodological quality assessment was completed for all included studies, including assessment of the risk of bias and strength of evidence. The primary outcome was change in hemoglobin and the secondary outcomes were drain output, transfusion requirements, and complications. Pooled outcomes assessing changes in hemoglobin, drain output, and transfusion requirements were determined. RESULTS Five articles (n = 629 patients), including 3 Level-I and 2 Level-III studies, were included. Pooled analysis demonstrated a significant reduction in hemoglobin change (mean difference [MD], -0.64 g/dL; 95% confidence interval [CI], -0.84 to -0.44 g/dL; p < 0.00001) and drain output (MD, -116.80 mL; 95% CI, -139.20 to -94.40 mL; p < 0.00001) with TXA compared with controls. TXA was associated with a point estimate of the treatment effect suggesting lower transfusion requirements (55% lower risk); however, the wide CI rendered this effect statistically nonsignificant (risk ratio, 0.45; 95% CI, 0.18 to 1.09; p = 0.08). Findings were robust with sensitivity analysis of pooled outcomes from only Level-I studies. CONCLUSIONS Moderate-strength evidence supports use of TXA for decreasing blood loss in primary shoulder arthroplasty. Further research is necessary to evaluate the efficacy of TXA in revision shoulder arthroplasty and to identify the optimal dosing and route of administration of TXA in shoulder arthroplasty.
