Sharaby MMF, El-Deeb YM
International orthopaedics. 2022
Abstract
PURPOSE Pelvic and acetabular surgery is associated with one of the highest amounts of blood loss. Tranexamic acid is a good choice to reduce blood loss during this type of surgery. However, being antifibrinolytic drug, the chance to have coagulation complications including DVT is a risk that should be considered particularly in such major trauma patients with the body's response to trauma and with possible prolonged bed stay. The aim of this study is to evaluate the effectiveness of intravenous tranexamic acid injection during pelvic and acetabular surgery for reduction of blood loss during surgery and after surgery and to evaluate any possible complications for its use. METHODS This prospective randomized clinical trial includes 97 patients divided between two groups; group 1 (G1) which received TXA, while the second group (G2) is the control group. The primary outcome measures were total blood loss (TBL), allogenic blood units transfused, and the blood lost intra-operatively (IBL). The TBL was calculated by the haemoglobin balance method while the intra-operative blood loss was measured by the gravimetric method. Any complications related to the drug were evaluated particularly DVT. RESULTS The study showed significantly less TBL (G1 = 829.7 ± 219.2, G2 = 1036.9 ± 314.9) and blood transfusion (G1 = 52.4 ± 40 g, G2 = 89.4 ± 60.6 g) in G1 compared to the G2. CONCLUSION This study proved the possible reduction of TBL and the need of blood transfusion by the use of TXA in pelvic and acetabular injuries.

Abstract
IMPORTANCE Post-cardiopulmonary bypass (CPB) coagulopathy and bleeding are among the most common reasons for blood product transfusion in surgical practices. Current retrospective data suggest lower transfusion rates and blood loss in patients receiving prothrombin complex concentrate (PCC) compared with plasma after cardiac surgery. OBJECTIVE To analyze perioperative bleeding and transfusion outcomes in patients undergoing cardiac surgery who develop microvascular bleeding and receive treatment with either PCC or plasma. DESIGN, SETTING, AND PARTICIPANTS A single-institution, prospective, randomized clinical trial performed at a high-volume cardiac surgical center. Patients were aged 18 years or older and undergoing cardiac surgery with CPB. Patients undergoing complex cardiac surgical procedures (eg, aortic replacement surgery, multiple procedures, or repeated sternotomy) were preferentially targeted for enrollment. During the study period, 756 patients were approached for enrollment, and 553 patients were randomized. Of the 553 randomized patients, 100 patients met criteria for study intervention. INTERVENTIONS Patients with excessive microvascular bleeding, a prothombin time (PT) greater than 16.6 seconds, and an international normalized ratio (INR) greater than 1.6 were randomized to receive treatment with either PCC or plasma. The PCC dose was 15 IU/kg or closest standardized dose; the plasma dose was a suggested volume of 10 to 15 mL/kg rounded to the nearest unit. MAIN OUTCOMES AND MEASURES The primary outcome was postoperative bleeding (chest tube output) from the initial postsurgical intensive care unit admission through midnight on postoperative day 1. Secondary outcomes were PT/INR, rates of intraoperative red blood cell (RBC) transfusion after treatment, avoidance of allogeneic transfusion from the intraoperative period to the end of postoperative day 1, postoperative bleeding, and adverse events. RESULTS One hundred patients (mean [SD] age, 66.8 [13.7] years; 61 [61.0%] male; and 1 [1.0%] Black, 1 [1.0%] Hispanic, and 98 [98.0%] White) received the study intervention (49 plasma and 51 PCC). There was no significant difference in chest tube output between the plasma and PCC groups (median [IQR], 1022 [799-1575] mL vs 937 [708-1443] mL). After treatment, patients in the PCC arm had a greater improvement in PT (effect estimate, -1.37 seconds [95% CI, -1.91 to -0.84]; P < .001) and INR (effect estimate, -0.12 [95% CI, -0.16 to -0.07]; P < .001). Fewer patients in the PCC group required intraoperative RBC transfusion after treatment (7 of 51 patients [13.7%] vs 15 of 49 patients [30.6%]; P = .04); total intraoperative transfusion rates were not significantly different between groups. Seven (13.7%) of 51 patients receiving PCCs avoided allogeneic transfusion from the intraoperative period to the end of postoperative day 1 vs none of those receiving plasma. There were no significant differences in postoperative bleeding, transfusions, or adverse events. CONCLUSIONS AND RELEVANCE The results of this study suggest a similar overall safety and efficacy profile for PCCs compared with plasma in this clinical context, with fewer posttreatment intraoperative RBC transfusions, improved PT/INR correction, and higher likelihood of allogeneic transfusion avoidance in patients receiving PCCs. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02557672.

BT, Kondareddy KM, AR, NR, ESRR, Prakash R
Cureus. 2022;14(1):e21362
Abstract
AIM: The present study aims to determine the efficacy of bovine hydroxyapatite and collagen (G-graft) mixed with platelet-rich fibrin (PRF) used as a scaffold and chorion membrane as a barrier in post-extraction sockets with extraction sites alone. METHODS AND MATERIAL Thirty individuals were randomly assigned into two groups. In the control group, after debridement of the extracted tooth socket, no additional treatment was done. In the test group, after debridement of the extracted tooth socket, the sockets were filled with bovine hydroxyapatite and collagen (G-graft) mixed with PRF. They were covered by a chorion membrane, and a non-absorbable suture material was used to secure the membrane in place. Clinical parameters assessed were plaque index, gingival index, buccolingual width, buccal bone plate height, and lingual bone plate height at baseline and at six months. RESULTS Clinically, there was a more significant reduction in the buccolingual width of the control group than the test group after six months. A statistically significant difference between the two groups for vertical ridge height at the mesial and distal socket sites was observed. No statistically significant difference in buccal and lingual bone plate height was observed between the two groups (p>0.05). CONCLUSIONS Both groups showed a significant reduction in the Buccolingual width, but it was less in the ridge preservation group. Thus, the use of G-graft with PRF and chorion membrane was highly effective in ridge preservation. Key messages: Natural bovine bone mineral, along with PRF and chorion as a membrane, can be utilized effectively for ridge preservation in extracted tooth sockets due to periodontal disease.

Abstract
BACKGROUND Esophagogastric variceal bleeding is the most common lethal factor for patients with cirrhotic portal hypertension. We firstly developed a laparoscopic splenectomy and azygoportal disconnection (LSD) with intraoperative endoscopic variceal ligation (LSDL) technique. In this study, we aimed to evaluate whether LSDL is feasible and safe and whether LSDL can effectively prevent esophagogastric variceal re-bleeding (EVR), as compared with single LSD. METHODS In this randomized controlled single-center study, 88 patients with cirrhosis who had esophagogastric variceal bleeding and hypersplenism were randomly assigned to receive either LSD (n = 44) or LSDL (n = 44) between January 2020 and December 2021. The primary outcome was EVR. RESULTS No patients withdrew from the study. There were no significant differences in estimated blood loss, incidence of blood transfusion, time to first flatus and off-bed activity, or postoperative hospital stay between the two groups. Compared with that in the LSD group, operation time was significantly longer in the LSDL group (138.5 ± 19.4 min vs. 150.3 ± 19.0 min, P < 0.05); however, LSDL was associated with a significantly decreased EVR rate at 1-year follow-up (8/44 vs. 1/44, P < 0.05). Univariate analysis and multivariate logistic regression revealed that LSDL was a significant independent protective factor against EVR in comparison with LSD (relative risk: 0.105, 95% confidence interval 0.012-0.877; P = 0.037). CONCLUSIONS Our newly developed LSDL procedure is not only technically feasible and safe; it also contributed to lowering the EVR risk more so than single LSD. TRIAL REGISTRATION We registered our research at https://www. CLINICALTRIALS gov/ . The name of research registered is "Laparoscopic Splenectomy and Azygoportal Disconnection with Intraoperative Endoscopic Variceal Ligation." The trial registration identifier at clinicaltrials.gov is NCT04244487.

Kim, C. H., Park, Y. B., Lee, J. S., Jung, H. S.
Journal of Shoulder and Elbow Surgery. 2022;31(2):428-436
Abstract
BACKGROUND Although surgical treatment is considered reliable for lateral elbow tendinosis, local injection therapy may be preferable, as it avoids surgery. Among a number of local injections, platelet-rich plasma has been used successfully to treat lateral elbow tendinosis. The purpose of this study was to compare the outcomes in patients treated with either platelet-rich plasma injections or surgery for lateral elbow tendinosis using a systematic literature review and meta-analysis. METHODS MEDLINE, Embase, and Cochrane Library databases were systematically searched for studies published before March 1, 2021, that compared platelet-rich plasma with operative treatment for lateral elbow tendinosis. The pooled analysis was designed to compare the visual analog scale scores and the Patient-Related Tennis Elbow Evaluation scores between the platelet-rich plasma and surgical treatment groups at serial time points. RESULTS We included 5 studies involving 340 patients with lateral elbow tendinosis, comprising of 154 patients treated with platelet-rich plasma and 186 patients who underwent surgical treatment. The pooled analysis showed no statistically significant differences in the visual analog scale scores at any of the follow-up time points, namely, 2 months (mean difference [MD] 1.11, 95% confidence interval [CI] -2.51 to 4.74, P = .55, I(2) = 94%), 6 months (MD 0.80, 95% CI -2.83 to 4.42, P = .67, I(2) = 92%), and 12 months (MD -0.92, 95% CI -4.63 to 2.80, P = .63, I(2) = 93%) postintervention and in the Patient-Related Tennis Elbow Evaluation scores at 12 weeks (MD -1.86, 95% CI -22.30 to 18.58, P = .86, I(2) = 81%), 24 weeks (MD -3.33, 95% CI -21.82 to 15.17, P = .72, I(2) = 74%), and 52 weeks (MD -3.64, 95% CI -19.65 to 12.37, P = .66, I(2) = 69%) postintervention. CONCLUSIONS Local platelet-rich plasma injections and surgical treatment produced equivalent pain scores and functional outcomes in patients with lateral elbow tendinosis. Thus, platelet-rich plasma injections may represent a reasonable alternative treatment for patients who are apprehensive to proceed with surgery or for poor surgical candidates.

Abstract
OBJECTIVES This meta-analysis aims to assess tranexamic acid (TXA) effectiveness and safety in lumbar surgery. PATIENTS AND METHODS Renewals of randomized-controlled trials (RCTs) were conducted utilizing databases of medical literature such as PubMed, China Science and Technology Journal Database, Cochrane Library, China National Knowledge Infrastructure (CNKI), and EMBASE to compare principal and safety endpoints. The risk ratio (RR), standard mean difference (SMD), and 95% confidence intervals (CIs) were calculated. For the evaluation of the quality of the included studies, the Cochrane risk of bias criteria were utilized by two authors. RESULTS In total, 49 articles were enrolled that included 4,822 patients. Of the patients, 2,653 were administered TXA and 2,169 were in the control group. The findings indicated that TXA was capable of significantly lowering postoperative blood loss (PBL), transfusion rate, transfusion volume, total blood loss (TBL), intraoperative blood loss (IBL), and drainage compared to the control group. Besides, hemoglobin (Hb) and hematocrit (Hct) values were higher in the TXA group compared to the control group. As the safety endpoints, TXA significantly reduced D-dimer levels compared to the control group; however, both TXA and control groups had no significant variations in deep venous thrombosis (DVT). Subgroup analysis was administrated according to the administration method of TXA and the operation type and intravenous and topical TXA were combined in the meta-analysis. CONCLUSION This meta-analysis showed that TXA had the potential to significantly lower PBL, transfusion rate, transfusion volume, TBL, IBL, and drainage compared to the control group. Besides, Hb and Hct values were higher in the TXA group compared to the control group. Its hemostatic potential after lumbar spine surgery is trustworthy. It is still controversial in safety endpoints that TXA can significantly reduce D-dimer compared to the control group, without no significant variations in DVT in both the TXA and control groups.
PICO Summary
Population
Patients undergoing lumbar surgery (49 studies, n= 4,822).
Intervention
Tranexamic acid (TXA), (n= 2,653).
Comparison

Abstract
OBJECTIVES To determine the effect of intraoperative antifibrinolytics, including tranexamic acid (TXA), aminocaproic acid (EACA), or aprotinin, on bleeding in children undergoing cardiac surgery with cardiopulmonary bypass (CPB). DATA SOURCES Relevant articles were systematically searched from Ovid MEDLINE, Ovid EMBASE, CINAHL, Cochrane Library, and Web of Science to November 15, 2021. STUDY SELECTION Abstracts were screened, and full texts were reviewed using predetermined inclusion and exclusion criteria using the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. DATA EXTRACTION A standardized data extraction tool was used. DATA SYNTHESIS Sixty-eight studies including 28,735 patients were analyzed. TXA compared with placebo resulted in a mean decrease in chest tube output of 9.1 mL/kg (95% CI, 6.0-12.3 mL/kg), I2 equals to 65.2%, p value of less than 0.001, platelet requirement of 2.9 mL/kg (95% CI, 0.1-5.8 mL/kg), I2=72.5%, p value less than 0.001 and plasma requirement of 4.0 mL/kg (95% CI, 0.6-7.2 mL/kg), I2 equals to 94.5%, p value less than0.001. Aprotinin compared with placebo resulted in a mean decrease in chest tube output of 4.3 mL/kg (2.4-6.2 mL/kg), I2 equals to 66.3%, p value of less than 0.001, platelet transfusion of 4.6 mL/kg (95% CI, 0.6-8.6 mL/kg), I2 equals to 93.6%, p value of less than 0.001, and plasma transfusion of 7.7 mL/kg (95% CI, 2.1-13.2 mL/kg), I2 equals to 95.3%, p value of less than 0.001. EACA compared with placebo resulted in a mean decrease in chest tube output of 9.2 mL/kg (2.3-21.0 mL/kg), I2 equals to 96.4%, p value of less than 0.001, RBC transfusion of 7.2 mL/kg (95% CI, 2.4-12.1 mL/kg), I2 equals to 94.5%, p value equals to 0.002, and platelet transfusion of 10.7 mL/kg (95% CI, 2.9-18.5 mL/kg), I2 equals to 0%, p value of less than 0.001. No statistical difference was observed in chest tube output when TXA was compared with aprotinin. Subgroup analysis of cyanotic patients showed a significant decrease in chest tube output, platelet requirement, and plasma requirement for patients receiving aprotinin. Overall, the quality of evidence was moderate. CONCLUSIONS Antifibrinolytics are effective at decreasing blood loss and blood product requirement in children undergoing cardiac surgery with CPB although the quality of evidence is only moderate.

Abstract
Liposuction remains one of the most frequently performed cosmetic surgical procedures and its popularity is increasing every year. However, since its inception, justified concerns regarding patient safety have placed limits on the volume of fat that can be aspirated, influenced by hemodynamic fluctuations and blood loss during liposuction. Tranexamic acid (TXA) is an antifibrinolytic agent that competitively inhibits the conversion of plasminogen to plasmin, thus preventing the binding and degradation of fibrin. Despite the existence of evidence of the effectiveness of TXA in orthopedic and cardiac surgeries, there is little evidence of its use in liposuction. The objective of this study was to evaluate the efficacy and safety of tranexamic acid in the control of surgical bleeding in patients undergoing liposuction, through a prospective, open, randomized and controlled clinical trial. Two groups of 25 participants each were formed to whom the application of TXA in a tumescent solution prior to liposuction or liposuction with the traditional technique was randomly assigned. The results showed a decrease in blood loss reflected by the differences in the final hematocrit values, as well as decrease in the same per aspirated volume (p = 0.003). No adverse events were found related with the TXA application and no blood transfusions were required in this group, in contrast to the control group where the need for blood transfusion was present in 20% of the intervened participants.

Anesthesiology research and practice. 2022;2022:3993452
Abstract
INTRODUCTION Cell salvaging is well established in the blood management of cardiac patients, but there remain some concerns about its effects on perioperative bleeding and transfusion variables. This randomized controlled study investigated the potential effects of the centrifuged end-product on bleeding, transfusion rates, and other transfusion-related variables in adult cardiac surgery patients submitted to extracorporeal circulation. MATERIALS AND METHODS Patients were randomly chosen to receive (cell-salvage group, 99 patients) or not to receive (control group, 110 patients) the centrifuged product of a cell salvage apparatus. Bleeding and transfusion rates according to the universal definition of perioperative bleeding (UDPB) classification, postoperative hemoglobin, coagulation, and oxygenation indices were recorded and compared between the groups. RESULTS Both groups had almost identical bleeding and transfusion rates (median value: 2 units of red blood cells (RBC) and no units of fresh frozen plasma (FFP) and platelets (PLT) for both groups, p > 0.05). Patients in the cell-salvage group presented slightly higher hemoglobin concentrations (10.6 ± 1.1 vs. 10.1 ± 1.7 g/dL, p < 0.05, respectively) and a tendency towards better oxygenation indices (P(a)O(2)/F(i)O(2): 241 ± 94 vs. 207 ± 84, p=0.013) in the postoperative period albeit with a tendency for prolongation of prothrombin time (INR: 1.31 ± 0.18 vs. 1.26 ± 0.12, p=0.008). CONCLUSION Within the study's constraints, the perioperative use of the cell salvage concentrate does not seem to affect bleeding or transfusion variables, although it could probably ameliorate postoperative oxygenation in adult cardiac surgery patients. A tendency to promote coagulation disturbances was detected.

Abstract
OBJECTIVES The purpose of this randomized controlled clinical trial was to compare and evaluate the clinical effects of concentrated growth factor (CGF) and advanced platelet-rich fibrin (A-PRF) applied together with coronally advanced flap (CAF) technique using a microsurgical approach in the treatment of type I multiple gingival recessions (GR). MATERIALS AND METHODS Sixteen patients with multiple recession defects (Cairo type I) were included in this randomized and controlled study. Forty-five gingival recession defects were randomly equally divided into three groups (n = 15): CAF + CGF (test site); CAF + A-PRF (test site), and CAF alone (control site). Clinical attachment level (CAL), vertical gingival recession (VGR), horizontal gingival recession (HGR), gingival thickness (GT), width of keratinized gingiva (KGW), percentages of the mean (MRC), and complete root coverage (CRC), patient esthetic score (PES), and hypersensitivity score (HS) were recorded at baseline and 6 months after surgery. Patient comfort score (PCS) was evaluated at the day of surgery. RESULTS Significant improvements were determined in CAL, VGR, HGR, KGW, and GT at 6 months when compared to baseline levels in intra-group comparisons for all groups, and also GT was increased in CAF + A-PRF and CAF + CGF compared to CAF alone at 6 months in intergroup comparisons (p < 0.05). At 6 months, MRC was detected 85.66 ± 22.68% in the CAF + CGF, 90.88 ± 20.87% in the CAF + A-PRF, and 75.10 ± 32,37% in the CAF alone, and a significant increase was detected in the CAF + A-PRF group compared to CAF alone (p < 0.05). CRC in CAF + CGF was 66.66%, in CAF + A-PRF 80% and in CAF alone was 53.33% (p > 0.05). PES and HS values showed significant improvement from baseline to 6 months for all groups and also in CAF + CGF and CAF + A-PRF compared to CAF alone at 6 months in intergroup comparisons (p < 0.05). CONCLUSIONS The present study showed that the use of A-PRF and CGF membranes in GR therapy may have an additional benefit in GT increase and also A-PRF may increase the percentages of MRC. The use of A-PRF and CGF membranes may be beneficial in terms of improving patient-related parameters. CLINICAL RELEVANCE A-PRF and CGF may be superior to CAF alone in terms of patient-related parameters and GT increase in multiple recession defects.
