European journal of orthopaedic surgery & traumatology : orthopedie traumatologie. 2022
Abstract
AIM: The ideal route of tranexamic acid (TXA) administration in total hip arthroplasty (THA) or total knee arthroplasty (TKA) remains controversial. This study aims to identify the optima route of TXA administration in THA or TKA. METHODS PUBMED, EMBASE, MEDLINE and CENTRAL database were systematically searched until 4 August 2021 for randomised studies that compared intravenous (IV) or intra-articular (IA) administration of TXA in THA or TKA. RESULTS Sixty-seven studies enrolling 8335 patients (IA: 4162; IV: 4173) were eligible for quantitative and qualitative analysis. Comparable results were demonstrated in the incidence of venous thromboembolisation (OR:0.96, p = 0.84), total blood loss (MD: - 9.05, p = 0.36), drain output (MD: - 7.36, p = 0.54), hidden blood loss (MD: - 6.85, p = 0.47), postoperative haemoglobin level (MD: 0.01, p = 0.91), haemoglobin drop (MD: - 0.10, p = 0.22), blood transfusion rate (OR: 0.99, p = 0.87), total adverse events (OR: 1.12, p = 0.28), postoperative range of motion (MD: 1.08, p = 0.36), postoperative VAS pain score (MD: 0.13, p = 0.24) and postoperative D-dimer level (MD: 0.61, p = 0.64). IV route of TXA administration was associated with significantly longer length of hospital stay compared to IA route of administration (MD: - 0.22, p = 0.01). CONCLUSION In this meta-analysis, both IV and IA route of TXA administration were equally effective in managing blood loss and postoperative outcomes in lower limb joints arthroplasty.

Effects of Platelet-Rich Plasma on Clinical Outcomes After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis
Zhu T, Zhou J, Hwang J, Xu X
Orthopaedic journal of sports medicine. 2022;10(1):23259671211061535
Abstract
BACKGROUND Many studies have documented the use of platelet-rich plasma (PRP) alongside anterior cruciate ligament (ACL) reconstruction (ACLR) in the management of ACL injury, but evidence on the benefits of PRP in improving the clinical outcomes of ACLR is inconsistent. PURPOSE To help in our understanding, we undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) that evaluated the effects of PRP on patient-reported functional scores, the clinical assessments of knee function and structure, and complications. STUDY DESIGN Systematic review; Level of evidence, 1. METHODS We searched 9 online databases for RCTs published in English or Chinese that examined the effects of PRP on ACLR. The primary outcome measures were visual analog scale (VAS) for pain and International Knee Documentation Committee (IKDC) scores. The secondary outcomes included KT-1000 arthrometer, pivot-shift test, Lysholm and Tegner scores, tunnel widening, graft characterization, and complications. Subgroup analyses were performed according to time of assessments. Fixed- and random-effects models were selected for data analysis. RESULTS A total of 14 studies were included. When PRP was injected to graft tunnels, the pooled VAS scores of the 2 groups were similar (P = .31), and the subgroup analysis found that VAS and IKDC only improved at 3 months postoperatively (P = .0003 and P < .00001, respectively). When PRP was used at the bone-patellar tendon-bone harvest sites, VAS was decreased in the first 6 months postoperatively (P < .00001), whereas IKDC score was not remarkably different (P = .07). After PRP injection, Lysholm scores at 3 months postoperatively was different between the 2 groups (P < .00001), but the Tegner scores (P = .86), KT-1000 measurements (P = .12), the positive rate of pivot-shift test (P = .64), the enlargement of tunnels (femoral, P = .91; tibial, P = .80), and the characterization of grafts (P = .05) were not different. No difference in complications was found in either group. CONCLUSION PRP applied alongside ACLR could reduce postoperative pain and improve knee function in the short and medium terms but is ineffective in the long term. PRP does not improve knee stability and the enlargement of tunnels and does not accelerate the healing of grafts. Further studies would be required.

Abstract
BACKGROUND The aim of this trial was to assess the effectiveness of quality improvement collaboratives to implement large-scale change in the National Health Service (NHS) in the UK, specifically for improving outcomes in patients undergoing primary, elective total hip or knee replacement. METHODS We undertook a two-arm, cluster randomised controlled trial comparing the roll-out of two preoperative pathways: methicillin-sensitive Staphylococcus aureus (MSSA) decolonisation (infection arm) and anaemia screening and treatment (anaemia arm). NHS Trusts are public sector organisations that provide healthcare within a geographical area. NHS Trusts (n = 41) in England providing primary, elective total hip and knee replacements, but that did not have a preoperative anaemia screening or MSSA decolonisation pathway in place, were randomised to one of the two parallel collaboratives. Collaboratives took place from May 2018 to November 2019. Twenty-seven Trusts completed the trial (11 anaemia, 16 infection). Outcome data were collected for procedures performed between November 2018 and November 2019. Co-primary outcomes were perioperative blood transfusion (within 7 days of surgery) and deep surgical site infection (SSI) caused by MSSA (within 90 days post-surgery) for the anaemia and infection trial arms, respectively. Secondary outcomes were deep and superficial SSIs (any organism), length of hospital stay, critical care admissions and unplanned readmissions. Process measures included the proportion of eligible patients receiving each preoperative initiative. RESULTS There were 19,254 procedures from 27 NHS Trusts included in the results (6324 from 11 Trusts in the anaemia arm, 12,930 from 16 Trusts in the infection arm). There were no improvements observed for blood transfusion (anaemia arm 183 (2.9%); infection arm 302 (2.3%) transfusions; adjusted odds ratio 1.20, 95% CI 0.52-2.75, p = 0.67) or MSSA deep SSI (anaemia arm 8 (0.13%); infection arm 18 (0.14%); adjusted odds ratio 1.01, 95% CI 0.42-2.46, p = 0.98). There were no significant improvements in any secondary outcome. This is despite process measures showing the preoperative pathways were implemented for 73.7% and 61.1% of eligible procedures in the infection and anaemia arms, respectively. CONCLUSIONS Quality improvement collaboratives did not result in improved patient outcomes in this trial; however, there was some evidence they may support successful implementation of new preoperative pathways in the NHS.

Otero AIP, Fernandes JCH, Borges T, Nassani L, Castilho RM, Fernandes GVO
Journal of clinical medicine. 2022;11(7)
Abstract
The purpose of this systematic review was to analyze sinus lifting procedures and to compare the efficiency of this treatment associated with the second generation of platelet-rich fibrin related to its effects on bone gain and to clarify the regenerative efficacy in sinus lift procedure, whether alone or as a coadjutant to other bone graft materials. The PICOT question was, "In clinical studies with patients needing a maxillary sinus lift (P), does the use of PRF either alone (I) or in conjunction with other biomaterials (C) improve the clinical outcome associated with bone gain and density (O), with at least three months of follow-up (T)?" An electronic search was conducted in the MEDLINE (PubMed), Science Direct, and Scopus databases through a search strategy. A total of 443 articles were obtained from the electronic database search. Sixteen articles met all criteria and were included in this review. Within the limitation of this study and interpreting the results carefully, it was suggested that a higher risk for implant failure after a sinus elevation might be seen in patients with residual bone ≤4 mm, and PRF application was effective, suggesting reducing the time needed for new bone formation.

Abstract
PURPOSE To investigate whether local administration of epsilon-aminocaproic acid (EACA) is effective and safe in reducing the post-operative blood loss in surgery for Sanders III-IV calcaneal fractures. METHODS Patients with Sanders III-IV calcaneal fractures who were hospitalized in our hospital from January 2016 to February 2021 and underwent open reduction internal fixation (ORIF) via lateral approach with an L-shaped incision were included in the current study. Eighty five patients were randomly divided into two groups, EACA group (43) and control group (42). Twenty milliliters of 5% EACA solution or normal saline was perfused into the incision of patients in EACA group and control group, respectively. The volume of post-operative drainage was investigated as the primary outcome. Post-operative blood test, coagulation test, and wound complications were analyzed as the secondary outcomes. RESULTS The volume of post-operative drainage at 24 and 48 h was 164.8 ± 51.4 ml, 18.9 ± 3.8 ml for patients in EACA group, and 373.0 ± 88.1 ml, 21.2 ± 4.4 ml for patients in the control group, respectively. EACA greatly reduced the post-operative blood loss compared to the control (normal saline). The difference between the two groups was statistically significant. No statistically significant difference was found between EACA group and control group with regard to the pre-operative, baseline characteristics. Post-operative blood test results demonstrated that haemoglobin and hematocrit were significantly higher in EACA compared to those of control group. No significant difference was found between EACA group and control group in terms of the platelet counts, prothrombin time (P.T.), activated partial prothrombin time (APTT), and wound complications. CONCLUSION Local administration of EACA is effective in post-operative blood loss reduction in ORIF surgeries for Sanders III-IV types of calcaneal fractures without increasing the incidence of periwound complication.

Neurosurgical review. 2022
Abstract
To summarize and analyze the clinical efficacy and safety of neuroendoscopic surgery (NES) in the treatment of patients for severe thalamic hemorrhage with ventricle encroachment (THVE). Eighty-three patients with severe THVE were treated in the Neurosurgery Department of Anqing Hospital Affiliated to Anhui Medical University from July 2019 to August 2021. Our study was approved by the ethics committee. The patients were randomly divided into NES group and extraventricular drainage (EVD) group. The hospital stay, Glasgow coma scale (GCS) scores on the 1st and 14th days postoperatively, the incidence of intracranial infections, and the clearance of postoperative hematomas were compared and analyzed between the two groups. The patients had follow-up evaluations 6 months postoperatively. The prognosis was evaluated based on the activity of daily living (ADL) score. A head CT or MRI was obtained to determine whether there was hydrocephalus, cerebral infarction, or other related complications. Eighty-three patients were randomly divided into 41 cases of NES group and 42 cases of EVD group. The length of postoperative hospital stay was 17.42 ± 1.53 days, the GCS scores were 6.56 ± 0.21, and 10.83 ± 0.36 on days 1 and 14, respectively; intracranial infections occurred in 3 patients (7.31%) and the hematoma clearance rate was 83.6 ± 5.18% in the NES group, all of which were significantly better than the EVD group (P < 0.05). After 6 months of follow-up, 28 patients (68.29%) had a good prognosis, 5 patients (12.19%) died, and 4 patients (9.75%) had hydrocephalus in the NES group. In the EVD group, the prognosis was good in 15 patients (35.71%), 12 patients (28.57%) died, and 17 patients (40.47%) had hydrocephalus. The prognosis, mortality rate, and incidence of hydrocephalus in the NES group were significantly better than the EVD group (P < 0.05). Compared to traditional EVD, NES for severe THVE had a higher hematoma clearance rate, and fewer intracranial infections and patients with hydrocephalus, which together improve the clinical prognosis and is thus recommended for clinical use.

Intravenous iron supplementation treats anemia and reduces blood transfusion requirements in patients undergoing coronary artery bypass grafting-A prospective randomized trial
Shokri H, Ali I
Annals of cardiac anaesthesia. 2022;25(2):141-147
Abstract
STUDY OBJECTIVE Preoperative anemia results in two- to sixfold increased incidence of perioperative blood transfusion requirements and reduced postoperative hemoglobin (Hb) level. This prospective study was designed to investigate the effect of preoperative intravenous infusion of iron on Hb levels, blood transfusion requirements, and incidence of postoperative adverse events in patients undergoing coronary artery bypass grafting. DESIGN Prospective randomized trial. SETTING Academic university hospital. PATIENTS Eighty patients (52-67 years old) underwent coronary artery bypass grafting and received either iron therapy or saline infusion preoperatively. INTERVENTIONS Patients were randomly allocated to iron or placebo groups. In the iron group, patients received a single intravenous dose of ferric carboxymaltose (1000 mg in 100 mL saline) infused slowly over 15 min 7 days before surgery. In placebo group, patients received a single intravenous dose of saline (100 mL saline) infused slowly over 15 min 7 days before surgery. MEASUREMENTS Patients were followed up with regards to incidence of anemia, Hb level on admission, preoperatively, postoperatively, 1 week and 4 weeks after discharge, aortic cross-clamp time, the number of packed red blood cells (pRBCs) units, the percentage of reticulocytes pre-postoperatively and 1 week later, hospital stay and intensive care unit (ICU) stay length, and the incidence of postoperative complications. MAIN RESULTS Iron therapy was associated with lower incidence of anemia 4 weeks after discharge (P < 0.001). Hb level was significantly higher in the iron group compared to the placebo group preoperatively and postoperatively, and 4 weeks after discharge (P < 0.001). Iron therapy resulted in shorter hospital and ICU stay (P < 0.001) and shorter aortic cross-clamp time, reduced pRBCs requirements postoperatively. Percentage of reticulocytes was significantly higher in placebo group than in iron group postoperatively and 1 week after discharge and the incidence of postoperative complications was similar to the placebo group. CONCLUSIONS Preoperative IV iron infusion is a safe and feasible way to manage preoperative anemia. Preoperative administration of IV iron is associated with a higher postoperative Hb level, shorter hospital and ICU stay, and reduced perioperative red blood cell transfusion requirements with insignificant difference in incidence of postoperative complications.

Cureus. 2022;14(3):e23091
Abstract
Background Total knee arthroplasty (TKA) is a procedure that has improved the quality of life of patients with knee arthritis. Postoperative pain and blood loss are the two major drawbacks of TKA which affect patient satisfaction and delay recovery and rehabilitation. Local infiltration analgesia has shown better results in controlling immediate postoperative pain, thus enabling early rehabilitation and mobilization, while local infiltration of antifibrinolytic agents has shown impressive results in controlling blood loss. In this study, we evaluate the effect of a combination of intra-articular infiltration of ropivacaine cocktail along with intra-articular instillation of tranexamic acid in reducing patient-reported postoperative pain and the level of blood loss control after TKA. Methodology Patients presenting with high-grade osteoarthritis and undergoing TKA were included and randomly allocated to two groups: one receiving the intra-articular infiltration (group A), and the other not receiving any infiltration (group B). Postoperative pain was measured through the Visual Analog Scale (VAS) every three hours for the first 24 hours, and then at 48 hours and 72 hours postoperatively. The need for additional analgesia, in the form of a slow epidural infusion, in patients experiencing severe postoperative pain was evaluated in both groups. Postoperative blood loss was assessed by measuring total drain output (in mL) and by comparing preoperative and postoperative (at 24 hours) hemoglobin, hematocrit drift, and blood transfusion rates. The duration of the postoperative hospital stay and the time taken to start postoperative knee mobilization exercises and weight-bearing were noted to assess the recovery and rehabilitation of the patients in the two groups. Results The study included 42 patients (group A, 22 patients; group B, 20 patients) with 28 knees in each group. Patients with intra-articular infiltration using ropivacaine cocktail with tranexamic acid showed excellent pain control compared to the non-infiltrated patients in the early 48 hours postoperatively. There was a significant drop in postoperative hemoglobin and hematocrit values in the non-infiltrated patients compared to the other group. Further, the intra-articular infiltration-instillation significantly reduced blood loss through the drain, the requirement of postoperative blood transfusions, and the duration of hospital stay. Conclusions It can be safely concluded that ropivacaine cocktail and tranexamic acid instillation postoperatively in knee arthroplasty patients is a very useful and effective technique to reduce postoperative pain and blood loss.

Holmén A, Corderfeldt A, Lannemyr L, Dellgren G, Hansson EC
Journal of cardiothoracic and vascular anesthesia. 2022
Abstract
OBJECTIVES Patients with endocarditis requiring urgent valvular surgery with cardiopulmonary bypass are at a high risk of developing systemic inflammatory response syndrome and septic shock, necessitating intensive use of vasopressors after surgery. The use of a cytokine hemoadsorber (CytoSorb, CytoSorbents Europe GmbH, Germany) during cardiac surgery has been suggested to reduce the risk of inflammatory activation. The study authors hypothesized that adding a cytokine adsorber would reduce cytokine burden, which would translate into improved hemodynamic stability. DESIGN A randomized, controlled, nonblinded clinical trial. SETTING At a university hospital, tertiary referral center. PARTICIPANTS Nineteen patients with endocarditis undergoing valve surgery. INTERVENTION A cytokine hemoadsorber integrated into the cardiopulmonary bypass circuit. MEASUREMENTS AND MAIN RESULTS The accumulated norepinephrine dose in the intervention group was half or less at all postoperative time points compared to the control group, although it did not reach statistical significance; at 24 and 48 hours (median 36 [25-75 percentiles; 12-57] μg v 114 [25-559] μg, p = 0.11 and 36 [12-99] μg v 261 [25-689] μg, p = 0.09). There was no significant difference in chest tube output, but there was a significantly lower need for the transfusion of red blood cells (285 [0-657] mL v 1,940 [883-2,148] mL, p = 0.03). CONCLUSIONS There was no statistically significant difference between the groups with regard to vasopressor use after surgery for endocarditis with the use of a cytokine hemoadsorber during cardiopulmonary bypass. Additional, larger randomized controlled trials are needed to definitely assess the potential effect.

Hemostatic Efficacy of Absorbable Gelatin Sponges for Surgical Nail Matrixectomy after Phenolization-A Blinded Randomized Controlled Trial
Córdoba-Fernández A, Lobo-Martín A
Journal of clinical medicine. 2022;11(9)
Abstract
BACKGROUND Some studies have recommended combining germinal matrix excision with phenol ablation in the treatment of onychocryptosis. Matrixectomy after phenolization has been shown to be an effective modification to reduce the drawbacks associated with phenolization alone, although it increases the risk of minor postoperative bleeding. The present study aims to assess the effectiveness and safety of gelatin sponges as hemostatic agents in partial matrixectomy after phenolization. METHODS A comparative clinical trial in parallel groups was designed in 74 halluces (44 patients) with stage I, II, and III onychocryptosis. All participants were randomly assigned to 3 groups: Group A (control group), Group B (conventional gelatin sponge), and Group C (high porosity gelatin sponge). RESULTS The quantified mean blood loss in the first 48 h after surgery in patients in both experimental groups was significantly lower compared to the control group. The lowest mean blood loss was recorded in Group C (p < 0.001) and followed by Group B (p = 0.005). No adverse effects were recorded in any of the patients included in the experimental groups. CONCLUSIONS Hemostatic gelatin sponges were demonstrated to be effective and safe devices for the control of minor postoperative bleeding associated with matrixectomy after segmental phenolization.
