RESUMEN
Start balanced resuscitation early (pre-hospital if possible), either in the form of whole blood or 1:1:1 ratio. Minimize resuscitation with crystalloid to minimize patient morbidity and mortality. Trauma-induced coagulopathy can be largely avoided with the use of balanced resuscitation, permissive hypotension, and minimized time to hemostasis. Using protocolized "triggers" for massive and ultramassive transfusion will assist in minimizing delays in transfusion of products, achieving balanced ratios, and avoiding trauma induced coagulopathy. Once "audible" bleeding has been addressed, further blood product resuscitation and adjunct replacement should be guided by viscoelastic testing. Early transfusion of whole blood can reduce patient morbidity, mortality, decreases donor exposure, and reduces nursing logistics during transfusions. Adjuncts to resuscitation should be guided by laboratory testing and carefully developed, institution-specific guidelines. These include empiric calcium replacement, tranexamic acid (or other anti-fibrinolytics), and fibrinogen supplementation.

This study uses machine learning and population data to analyze major determinants of blood transfusion among patients with hip arthroplasty. Retrospective cohort data came from Korea National Health Insurance Service claims data for 19,110 patients aged 65 years or more with hip arthroplasty in 2019. The dependent variable was blood transfusion (yes vs no) in 2019 and its 31 predictors were included. Random forest variable importance and Shapley Additive Explanations were used for identifying major predictors and the directions of their associations with blood transfusion. The random forest registered the area under the curve of 73.6%. Based on random forest variable importance, the top-10 predictors were anemia (0.25), tranexamic acid (0.17), age (0.16), socioeconomic status (0.05), spinal anesthesia (0.05), general anesthesia (0.04), sex (female) (0.04), dementia (0.03), iron (0.02), and congestive heart failure (0.02). These predictors were followed by their top-20 counterparts including cardiovascular disease, statin, chronic obstructive pulmonary disease, diabetes mellitus, chronic kidney disease, peripheral vascular disease, liver disease, solid tumor, myocardial infarction and hypertension. In terms of max Shapley Additive Explanations values, these associations were positive, e.g., anemia (0.09), tranexamic acid (0.07), age (0.09), socioeconomic status (0.05), spinal anesthesia (0.05), general anesthesia (0.04), sex (female) (0.02), dementia (0.03), iron (0.04), and congestive heart failure (0.03). For example, the inclusion of anemia, age, tranexamic acid or spinal anesthesia into the random forest will increase the probability of blood transfusion among patients with hip arthroplasty by 9%, 7%, 9% or 5%. Machine learning is an effective prediction model for blood transfusion among patients with hip arthroplasty. The high-risk group with anemia, age and comorbid conditions need to be treated with tranexamic acid, iron and/or other appropriate interventions.

OBJECTIVE: Microneedling with topical tranexamic acid (TXA) is a novel treatment option for melasma; however, the efficacy and safety of this combined administration therapy is in controversial. This study is conducted to address this issue of this technique in melasma. METHODS: An extensive literature review was performed to identify relevant trials, including randomized split-face studies, randomized controlled trials and prospective non-randomized split-face studies, comparing microneedling plus topical TXA to routine treatments or placebo. The primary outcomes were changes of the Melasma Area Severity Index (MASI)/modified MASI (mMASI)/hemi MASI between before and after treatment, as well as the changes between a particular treatment and microneedling plus TXA. The mean differences (MDs) and 95% confidence intervals (CIs) were calculated for the reduction of melasma severity scores from baseline to each time point. In contrast, the standard mean differences (SMDs) and 95% CIs were calculated for the differences in reduction in melasma severity scores between the experimental and control groups at each time point. RESULTS: A total of 16 trials were included in the systematic review and data synthesis. The pooled analysis demonstrated that MASI, mMASI, and hemiMASI scores decreased significantly at 4 weeks (MD = 1.85; 95% CI = 1.15-2.54), 8 weeks (MD = 3.28; 95% CI = 2.31-4.24), 12 weeks (MD = 4.73; 95% CI = 2.79-6.50), 16 weeks (MD = 3.18; 95% CI = 1.50-4.85), and 20 weeks (MD = 3.20; 95% CI = 1.95-4.46) after treatment when compared with baseline. The reduction in melasma severity scores of microneedling with TXA group at 4 weeks was more significant than the routine treatment group (SMD = 0.97; 95% CI = 0.09-1.86), while insignificant at 8 weeks (SMD = 1.21; 95% CI = -0.17 to 2.59), 12 weeks (SMD = 0.63; 95% CI = -0.03 to 1.29), 16 weeks (SMD = 0.61; 95% CI = -2.85 to 4.07), or 20 weeks (SMD = 1.04; 95% CI = -1.28 to 3.36). CONCLUSION: Despite the high heterogeneity across these studies, the current findings indicated that microneedling with topical TXA is an alternative treatment option for melasma treatment; and more well-designed studies are needed to confirm it.

Background: This study aimed to evaluate the annual trends of transfusion rates and utilization of blood management agents in total knee arthroplasty (TKA) based on the operation type and to analyze the risk factors of transfusion after TKA. Methods: Using the Korean National Insurance claims database of 797,106 primary and revision TKAs between January 2008 and October 2019, data on the patients' characteristics, comorbidities, utilization of transfusion, and blood management agents were collected. The patients were categorized into three groups based on the operation type: primary, revision, and simultaneous bilateral TKA. The transfusion rate and utilization of blood management agents (intraoperative tranexamic acid [TXA] and preoperative iron supplements) were compared, and the risk factors for transfusion were evaluated. Results: After excluding the inaccurate data, 730,554 arthroplasties (636,292 primary, 10,540 revision, and 41,861 simultaneous bilateral TKAs) were identified. The transfusion rates of primary, revision, and simultaneous bilateral TKAs in 2019 were 64.0%, 67.7%, and 68.9%, respectively, which were significantly decreased compared with 83.2%, 88.0%, and 92.5% in 2008, respectively (p < 0.001). Conversely, the utilization of intraoperative TXA and preoperative iron supplements was significantly increased from 4.6% and 13.8%, respectively, in 2008 to 52.4% and 27.0%, respectively, in 2019 (p < 0.001). The utilization of intraoperative TXA and preoperative iron supplements significantly lowered the risk of transfusion after TKA (odds ratio [OR], 0.20; p < 0.001 and OR, 0.71; p < 0.001). Conclusions: The transfusion rate after TKA decreased gradually from 83.5% to 64.5% between 2008 and 2019 in South Korea corresponding with the increased utilization of blood management agents. Therefore, consistent attention to patient blood management should be emphasized to reduce the transfusion rate after TKA.

OBJECTIVES: Maxillomandibular fixation requires the jawbones to remain static. Mechanical cleaning is also carried out by brushing or with a water flosser to maintain the oral cavity in a hygienic state, but this cannot be considered sufficient. Mouthwashes are used as a substitute for mechanical cleaning or in a supplementary role after such cleaning. The aim is to evaluate the effectiveness of HABITPRO mouthwash, which contains cetylpyridinium chloride, dipotassium glycyrrhizinate, and tranexamic acid in the specific environment created by maxillomandibular fixation used as an adjunct to mechanical cleaning. MATERIAL AND METHODS: A total of 55 patients who had undergone maxillomandibular fixation were randomly allocated to either a HABITPRO group (n = 29) or a placebo group (n = 26). To investigate their oral hygiene status, their plaque control record (PCR) was reviewed, and the caries-related bacterial counts, pH, acid buffering capacity, white blood cell count, and ammonia in saliva were measured immediately before maxillomandibular fixation, on Day 10 of fixation, and immediately after fixation was released. RESULTS: After approximately 2-3 weeks of mouthwash use, the PCR index also increased significantly in the placebo group compared with baseline, whereas it remained almost steady in the HABITPRO group. Additionally, salivary ammonia levels decreased significantly in the HABITPRO group compared to that of the placebo group. CONCLUSIONS: Even with maxillomandibular fixation, continued gargling with HABITPRO mouthwash in the perioperative period as an adjunct to mechanical cleaning can help maintain better oral hygiene and reduce bacterial counts.

BACKGROUND: The objectives of the researchers are as follows: First, to investigate whether intraoperative or postoperative administration of Intravenous (IV) iron supplements in patients undergoing primary total knee arthroplasty (TKA) can contribute to the hemoglobin recovery during the postoperative period (between 4 and 8 weeks after surgery). Second, to examine whether the administration of IV iron supplements during or immediately after TKA in patients undergoing primary TKA can reduce the need for allogenic blood transfusion during hospitalization. METHODS: Articles published between January 1, 1990, and June 30, 2023 were searched in PubMed, Cochrane, and Embase. The population, intervention, comparison, and outcome of this study are as follows; Population: Patients undergoing primary total knee arthroplasty; Intervention: Administration of IV iron supplements during or immediately after surgery; Comparison: Non-administration of IV iron supplements; Outcome: Degree of hemoglobin recovery (between 4 and 8 weeks after surgery) and the need for blood transfusion during hospitalization. RESULTS: There was a statistically significant difference in the amount of change in hemoglobin between iron supplementation group and non-iron supplementation group. The effect size were -0.44 (95% confidence interval: -0.69 to -0.19, P valueâ <â .001) in all patients. This means that the amount of change in hemoglobin were significantly reduced in the iron supplementation group than in the non-iron supplementation group. There was a statistically significant difference for post-operative transfusion rate between 2 groups. The effect size were 0.28 (95% confidence interval: 0.10-0.81, P valueâ =â .02) in all patients. This means that the post-operative transfusion rate was significantly less in the iron supplementation group than in the non-iron supplementation group. CONCLUSION: The administration of IV iron supplements during or after TKA surgery increases hemoglobin recovery between 4 and 8 weeks after surgery and reduces the need for allogeneic blood transfusion during hospitalization.

BACKGROUND: Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement. METHODOLOGY: This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented. RESULTS: Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups. CONCLUSION: The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.
CONTEXTE: L'hémorragie est une complication courante après une prostatectomie simple ouverte et les patients doivent parfois recevoir une transfusion sanguine. Il a été démontré que l'acide tranexamique réduit la perte de sang après une résection transurétrale de la prostate et une prostatectomie radicale ouverte. Cette étude a évalué l'effet de l'administration intraveineuse périopératoire d'acide tranexamique sur les pertes sanguines et les taux de transfusion sanguine chez des patients ayant subi une PSO pour hypertrophie bénigne de la prostate. MÉTHODOLOGIE: Il s'agissait d'une étude comparative de patients dont la prostate de 60 g et plus était documentée et qui devaient subir une PSO. L'hématocrite de base a été effectué un jour avant la chirurgie. Les patients ont été répartis aléatoirement dans le groupe acide tranexamique, qui a reçu de l'acide tranexamique periopératoire par voie intraveineuse, et dans le groupe sans TXA, qui a reçu un placebo. Tous les patients ont subi une prostatectomie rétropubienne simple ouverte. L'hématocrite postopératoire a été évalué, et la perte de sang calculée à l'aide de la formule de Gross modifiée. Le taux de transfusion a été documenté. RÉSULTATS: Cinquante-six patients ont participé à cette étude et ont été randomisés entre le groupe avec acide tranexamique et le groupe sans acide tranexamique. L'âge moyen des patients du groupe acide tranexamique était de 66,07 ±7,08 ans et était comparable à celui du groupe sans acide tranexamique qui était de 66,50 ± 8,80 ans (P =0,842). La perte sanguine totale médiane était plus faible dans le groupe avec acide tranexamique (502 ml, IQR 613) que dans le groupe sans acide tranexamique (801 ml, IQR 1069). La différence de la perte de sang médiane entre les deux groupes était de 299 ml (U 275, P 0,055). Le taux de transfusion sanguine était inférieur dans le groupe acide tranexamique (6 patients, 21%) par rapport au groupe sans acide tranexamique (11 patients, 39%), (P =0,146). Il n'y avait pas de différence dans les taux de complication entre les deux groupes. CONCLUSION: L'utilisation de l'acide tranexamique chez les patients subissant une prostatectomie simple ouverte a montré une tendance à la réduction de la perte de sang peropératoire et un besoin moindre de transfusion sanguine.

BACKGROUND: Bleeding and bleeding-related complications remain common after bipolar transurethral resection of the prostate (TURP) for benign prostatic hyperplasia. This may possibly lead to prolonged postoperative irrigation, catheterization, and hospital stay. The objective of this trial was to evaluate the effect of high-dose tranexamic acid (TXA) on perioperative blood loss in patients treated with bipolar TURP for prostate sizes between 30 and 80 g. METHODS: We conducted a single-center, prospective, double-blind, randomized controlled trial. Eighty patients were screened for inclusion between March 2020 and January 2023. After exclusion, 65 patients were randomized in two comparable groups. The TXA group (31 patients) received a TXA intravenous loading dose of 10 mg/kg over 30 min before induction, followed by a maintenance dose of 5 mg/kg/h over 12 h. The placebo group (34 patients) received an equal dose of saline infusion. We measured age, weight, preoperative prostate size, anticoagulant use, 5-alpha reductase inhibitor use, preoperative urinary tract infection, American Society of Anesthesiologists score, difference in pre- and 24 h postoperative hemoglobin and hematocrit levels, operative time, resected adenoma weight, duration of postoperative irrigation, total amount of postoperative irrigation fluid, indwelling catheter time, duration of hospital stay, blood transfusion rate, and 4-week complication rate. RESULTS: Baseline characteristics in both groups were comparable. Postoperative hemoglobin decrease in TXA versus placebo group was 1 versus 1.6 mg/dL, respectively (p = 0.04). In addition, the amount of postoperative irrigation fluid (10.7 vs. 18.5 L), irrigation time (24.3 vs. 37.9 h), catheterization time (40.8 vs. 53.7 h), and hospital stay (46.9 vs. 59.2 h) were statistically significant in favor of TXA use. No blood transfusions were carried out. Four-week complication rate was comparable between the two groups. CONCLUSIONS: Perioperative high-dose TXA seems beneficial in reducing hemoglobin loss, postoperative irrigation, catheterization time, and hospital stay in bipolar TURP for prostate sizes between 30 and 80 g, without increased risk of TXA-related thromboembolic events.

Background and Objectives: Total knee arthroplasty (TKA) involves blood loss, increasing the risk of postoperative anemia and delayed functional recovery. Intravenous (IV) iron supplementation limits postoperative anemia; however, the effectiveness of IV iron, administered one day before TKA, on postoperative anemia and functional recovery has scarcely been studied. Materials and Methods: We conducted a retrospective cohort study with propensity score matching using two consecutive groups of patients who underwent TKA using tranexamic acid: the iron group received 500 mg ferric derisomaltose intravenously one day before surgery (n = 46); the non-iron group did not (n = 46). Hemoglobin (Hb) level was determined at postoperative days (PODs) 2, 4, 6, 14, and 30. Ferritin, transferrin saturation (TSAT), and functional iron deficiency anemia (IDA) rate were measured at PODs 2, 4, 6, and 14. Length of hospital stay and transfusion rate were also evaluated. Results: The iron group had higher Hb levels at PODs 6, 14, and 30 and higher ferritin and TSAT at PODs 2, 4, 6, and 14. The functional IDA rate was significantly higher in the non-iron group at PODs 2, 4, 6, and 14. Length of hospital stay was significantly shorter in the iron group; however, the rate of transfusion did not differ between the two groups. Conclusions: IV iron administered one day before TKA was associated with postoperative anemia recovery and length of hospital stay; however, it did not lower the postoperative transfusion rate.

OBJECTIVE: To compare outcomes in males given perioperative tranexamic acid (TXA) during holmium laser enucleation of the prostate (HoLEP) to a historical cohort that did not receive TXA. METHODS: Our cohort included HoLEP patients (N = 1037) from August 2018 through November 2022. Exclusion criteria included history of stroke, transient ischemic attack, or coronary stent placed within 18 months. The primary predictor was TXA during HoLEP. The primary outcome variable was a return to the operating room (RTOR) for bleeding. Secondary outcomes included catheter reinsertion, transfusion, and clotting complications. Multivariable models evaluating associations of TXA with outcomes were adjusted for potential confounders. RESULTS: In our cohort, 214/1035 had one or more complications with 81 having a Clavien-Dindo Grade of 3a or higher, 114/1037 with catheter reinsertion, 36/1037 RTOR for bleeding, and 15/1035 had a transfusion. TXA use was not associated with 30-day RTOR. 3.7% of those without TXA had a RTOR, and 3.1% of those with TXA had a RTOR (adjusted odds ratio 0.63, 95% CI 0.28-1.38, P = .25). Transfusion rates were higher for those without TXA (2.0%) compared to with (0.5%). This was statistically significant after adjustment (adjusted odds ratio 0.13, 95% CI 0.03-0.69, P = .016) and after correction for multiple testing (corrected P = .048). TXA use was not associated with catheter reinsertion or clotting complications. CONCLUSION: Routine perioperative intravenous TXA in HoLEP patients was not associated with a reduction of RTOR for bleeding, catheter reinsertion, or clotting complications. TXA was associated with decreased transfusions with a low overall event rate of 1.4%.

Tranexamic acid (TXA) has been increasingly utilized in orthognathic surgery, aesthetic surgery, and craniofacial surgery. However, the risk of increasing venous thromboembolic events (VTE) must be carefully considered as TXA is a prothrombotic agent. Our study aimed to investigate the safety of TXA in the setting of facial feminization surgery. These patients are at an elevated risk for VTE at baseline given their uniform history of exogenous estrogen supplementation. A retrospective review of all patients that underwent facial feminization surgery at our medical center between December 2015 and September of 2022 was performed. Demographic information, procedure type, Caprini scores, hematoma rate, VTE rate, estimated blood loss, and operative time were all studied. Unpaired t tests were used to compare patients that received TXA and those who did not. In total, there were 79 surgeries performed during our study period. There were 33 surgeries (41.77%) that used TXA intraoperatively. Ten patients (12.65%) received anticoagulation postoperatively, 5 of whom received TXA intraoperatively. Of the 33 patients who received TXA, 30 patients remained on estrogen therapy. There was no statistically significant difference in VTE rates in patients who received TXA (n=33, 41.77%) and those who did not (n=46, 58.23%). Bleeding events, Caprini scores, estimated blood loss, and operative time were also not found to be significantly different between the 2 cohorts. The authors found no significant increase in VTE in facial feminization patients undergoing estrogen supplementation when intraoperative TXA was utilized. This is the first known report investigating the safety of TXA in this higher risk patient population.

BACKGROUND: Delays in the detection or treatment of postpartum hemorrhage can result in complications or death. A blood-collection drape can help provide objective, accurate, and early diagnosis of postpartum hemorrhage, and delayed or inconsistent use of effective interventions may be able to be addressed by a treatment bundle. METHODS: We conducted an international, cluster-randomized trial to assess a multicomponent clinical intervention for postpartum hemorrhage in patients having vaginal delivery. The intervention included a calibrated blood-collection drape for early detection of postpartum hemorrhage and a bundle of first-response treatments (uterine massage, oxytocic drugs, tranexamic acid, intravenous fluids, examination, and escalation), supported by an implementation strategy (intervention group). Hospitals in the control group provided usual care. The primary outcome was a composite of severe postpartum hemorrhage (blood loss, ≥1000 ml), laparotomy for bleeding, or maternal death from bleeding. Key secondary implementation outcomes were the detection of postpartum hemorrhage and adherence to the treatment bundle. RESULTS: A total of 80 secondary-level hospitals across Kenya, Nigeria, South Africa, and Tanzania, in which 210,132 patients underwent vaginal delivery, were randomly assigned to the intervention group or the usual-care group. Among hospitals and patients with data, a primary-outcome event occurred in 1.6% of the patients in the intervention group, as compared with 4.3% of those in the usual-care group (risk ratio, 0.40; 95% confidence interval [CI], 0.32 to 0.50; P<0.001). Postpartum hemorrhage was detected in 93.1% of the patients in the intervention group and in 51.1% of those in the usual-care group (rate ratio, 1.58; 95% CI, 1.41 to 1.76), and the treatment bundle was used in 91.2% and 19.4%, respectively (rate ratio, 4.94; 95% CI, 3.88 to 6.28). CONCLUSIONS: Early detection of postpartum hemorrhage and use of bundled treatment led to a lower risk of the primary outcome, a composite of severe postpartum hemorrhage, laparotomy for bleeding, or death from bleeding, than usual care among patients having vaginal delivery.

BACKGROUND: Acne vulgaris is a common skin disease that is more common in young population and it can be associated with some sequels after resolving the lesions. Post-inflammatory erythema is one of these complications that can be disturbing for patients and does not have any definite treatment. This study was aimed to evaluate the efficacy and safety of tranexamic acid (TA) as mesotherapy in treatment of post-acne erythema (PAE) treatment. METHOD: This clinical trial study was performed in the dermatology clinic on 17 patients with persistent PAE (3 months after acne recovery). Two sessions of treatment were performed by a physician with 2-week intervals; TA was injected as mesotherapy into the right side of each patient's face as the case group, while the opposite side was used as the control group. A Visioface device was used to compare before and after treatment photographs of each side of the face in color mode with quantitative measures such as lesions count, area, and area percent. RESULTS: Finally, 15 patients completed treatment sessions. There were statistically significant differences in right side lesions before and after treatment with p-values of 0.047, 0.002, and 0.035 for count, area, and area percent, respectively. There was no significant difference before and after treatment in terms of count, area. and area-percent on the left side. CONCLUSION: According to the results of this study, TA injection as mesotherapy for resolving PAE can be effective. However, due to small sample size, further studies are needed.

BACKGROUND: Traumatic hyphema is the entry of blood into the anterior chamber, the space between the cornea and iris, following significant injury to the eye. Hyphema may be associated with significant complications that uncommonly cause permanent vision loss. Complications include elevated intraocular pressure, corneal blood staining, anterior and posterior synechiae, and optic nerve atrophy. People with sickle cell trait or disease may be particularly susceptible to increases in intraocular pressure and optic atrophy. Rebleeding is associated with an increase in the rate and severity of complications. OBJECTIVES: To assess the effectiveness of various medical interventions in the management of traumatic hyphema. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2022, Issue 3); MEDLINE Ovid; Embase.com; PubMed (1948 to March 2022); the ISRCTN registry; ClinicalTrials.gov; and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). The last date of the search was 22 March 2022. SELECTION CRITERIA: Two review authors independently assessed the titles and abstracts of all reports identified by the electronic and manual searches. We included randomized and quasi-randomized trials that compared various medical (non-surgical) interventions versus other medical interventions or control groups for the treatment of traumatic hyphema following closed-globe trauma. We applied no restrictions on age, gender, severity of the closed-globe trauma, or level of visual acuity at time of enrollment. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane and assessed the certainty of evidence using GRADE. MAIN RESULTS: We included 23 randomized and seven quasi-randomized studies with a total of 2969 participants. Interventions included antifibrinolytic agents (systemic and topical aminocaproic acid, tranexamic acid, and aminomethylbenzoic acid), corticosteroids (systemic and topical), cycloplegics, miotics, aspirin, conjugated estrogens, traditional Chinese medicine, monocular versus bilateral patching, elevation of the head, and bed rest. We found no evidence of an effect on visual acuity for any intervention, whether measured within two weeks (short term) or for longer periods. In a meta-analysis of two trials, we found no evidence of an effect of aminocaproic acid on long-term visual acuity (RR 1.03, 95% confidence interval (CI) 0.82 to 1.29) or final visual acuity measured up to three years after the hyphema (RR 1.05, 95% CI 0.93 to 1.18). Oral tranexamic acid appeared to provide little to no benefit on visual acuity in four trials (RR 1.12, 95% CI 1.00 to 1.25). The remaining trials evaluated the effects of various interventions on short-term visual acuity; none of these interventions was measured in more than one trial. No intervention showed a statistically significant effect (RRs ranged from 0.75 to 1.10). Similarly, visual acuity measured for longer periods in four trials evaluating different interventions was also not statistically significant (RRs ranged from 0.82 to 1.02). The evidence supporting these findings was of low or very low certainty. Systemic aminocaproic acid reduced the rate of recurrent hemorrhage (RR 0.28, 95% CI 0.13 to 0.60), as assessed in six trials with 330 participants. A sensitivity analysis omitting two studies not using an intention-to-treat analysis reduced the strength of the evidence (RR 0.43, 95% CI 0.17 to 1.08). We obtained similar results for topical aminocaproic acid (RR 0.48, 95% CI 0.20 to 1.10) in two trials with 131 participants. We assessed the certainty of the evidence as low. Systemic tranexamic acid had a significant effect in reducing the rate of secondary hemorrhage (RR 0.33, 95% CI 0.21 to 0.53) in seven trials with 754 participants, as did aminomethylbenzoic acid (RR 0.10, 95% CI 0.02 to 0.41), as reported in one study. Evidence to support an associated reduction in risk of complications from secondary hemorrhage (i.e. corneal blood staining, peripheral anterior synechiae, elevated intraocular pressure, and development of optic atrophy) by antifibrinolytics was limited by the small number of these events. Use of aminocaproic acid was associated with increased nausea, vomiting, and other adverse events compared with placebo. We found no evidence of an effect on the number of adverse events with the use of systemic versus topical aminocaproic acid or with standard versus lower drug dose. The number of days for the primary hyphema to resolve appeared to be longer with the use of systemic aminocaproic acid compared with no use, but this outcome was not altered by any other intervention. The available evidence on usage of systemic or topical corticosteroids, cycloplegics, or aspirin in traumatic hyphema was limited due to the small numbers of participants and events in the trials. We found no evidence of an effect between a single versus binocular patch on the risk of secondary hemorrhage or time to rebleed. We also found no evidence of an effect on the risk of secondary hemorrhage between ambulation and complete bed rest. AUTHORS' CONCLUSIONS: We found no evidence of an effect on visual acuity of any of the interventions evaluated in this review. Although the evidence was limited, people with traumatic hyphema who receive aminocaproic acid or tranexamic acid are less likely to experience secondary hemorrhage. However, hyphema took longer to clear in people treated with systemic aminocaproic acid. There is no good evidence to support the use of antifibrinolytic agents in the management of traumatic hyphema, other than possibly to reduce the rate of secondary hemorrhage. The potentially long-term deleterious effects of secondary hemorrhage are unknown. Similarly, there is no evidence to support the use of corticosteroids, cycloplegics, or non-drug interventions (such as patching, bed rest, or head elevation) in the management of traumatic hyphema. As these multiple interventions are rarely used in isolation, further research to assess the additive effect of these interventions might be of value.

BACKGROUND: Tranexamic acid is used to treat pigmented disorder in dermatology for a long time however there are limited data for effectiveness of tranexamic acid for rejuvenation and improvement of wrinkle. Here we want to find the effectiveness of tranexamic acid as mesotherapy in improvement of periorbital wrinkle in a clinical trial study. METHODS: Patients with melasma who were treated with 4 session of tranexamic acid mesotherapy at intervals on 1 week were evaluated with Visioface device before starting and 1 month after last course of treatment. The outcomes including volume, area, area percent, and depth were measured by Visioface device. RESULTS: Mean of periorbital wrinkles volume before and after procedure were 89 271 and 74 639 pixel3 (px3 ), respectively. Very significant difference with p-value of <0.001 was detected at volume of patient wrinkles before and after treatment. Moreover, the mean of area (and area percent) of their periorbital wrinkles before and after therapeutic method were 8481 Px3 (1.131%) and 7184 Px3 (0.646%), respectively, with significant differences (both have p-value of <0.001).Mean of periorbital wrinkles depth at before and after treatment were 9.8 and 9.6, respectively, without remarkable difference (p-value was 0.257). CONCLUSION: Tranexamic acid mesotherapy significantly leads to reduced volume and area of wrinkles. Injection of tranexamic acid as mesotherapy seems to be effective in improvement of periorbital wrinkling.

PURPOSE OF REVIEW: Hemorrhage and trauma-induced coagulopathy cause significant morbidity and mortality in trauma patients. Although blood products are the cornerstone of resuscitation, these resources are scarce, necessitating alternatives. This review examines the use of alternative blood products in trauma as well as the literature supporting their use. RECENT FINDINGS: There is no single true blood product alternative. In recent years, there has been great progress in understanding trauma-induced pathophysiology and blood component alternatives. Products such as tranexamic acid and prothrombin complex concentrate have become well established and are frequently utilized in trauma centers, and many more alternatives are still undergoing further research and development. SUMMARY: Stabilization of hemorrhage and resuscitation is priority in trauma-induced coagulopathy treatment. Alternative products such as tranexamic acid, recombinant factors, prothrombic complex concentrate, fibrinogen concentrates, and desmopressin may also be considered based on the clinical context. Viscoelastic hemostatic assays such as rotational thromboelastometry and thromboelastography can help guide these efforts. Following initial stabilization, additional interventions such as iron supplementation, erythropoietin stimulating agents, and vitamin D may help with chronic sequela.

Context: Knee arthritis is the primary cause of disability in middle-aged and older adults. Total knee arthroplasty (TKA) is also a common treatment in clinics and has a remarkable effect on improving knee-joint function. However, TKA is an invasive procedure that includes a large amount of trauma. It can easily lead to an increase in perioperative blood loss coupled with a long operation time, which can increase the risk of postoperative complications, and also has a long recovery time. Objective: The study intended to analyze the value of tranexamic acid (TXA) plus progressive nursing in accelerating the postoperative rehabilitation of patients undergoing total knee arthroplasty (TKA). Design: The research team designed a prospective non-randomized controlled trial. Setting: The study took place at Cangzhou Hospital of Integrated Traditional Chinese Medicine (TCM) - Western Medicine (WM) Hebei in Cangzhou, Hebei, China. Participants: Participants were 115 patients with knee arthritis who underwent TKA at the hospital between February 2019 and October 2021. Intervention: Of the 115 participants, 55 were assigned to the control group and received conventional nursing care, and 60 were assigned to the intervention group and after surgery received TXA plus progressive nursing. Outcome Measures: The study measured blood loss postoperatively and identified any complications that participants experienced during treatment. At baseline and postintervention, the study also measured knee-joint range of motion (ROM), and the participants completed the Hospital for Special Surgery (HSS) knee survey, the Barthel Index for Activities of Daily Living (ADL), the Self-Rating Depression (SDS) and Self-Rating Anxiety (SAS) scales, a nursing-satisfaction survey, and the World Health Organization Quality of Life Bref (WHO-QOL-BREF) survey. Results: Postoperatively, the blood loss in the intervention group was significantly lower than that in control group, and the knee joint ROM was significantly better in the intervention group (P < .05). In addition, the postoperative Hospital for Special Surgery (HSS) and Barthel scores in the intervention group were significantly higher, and the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores were significantly lower in the intervention group compared with control group (P < .05). Moreover, a lower incidence of complications and better quality of life were determined for the intervention group (P < .05). Conclusions: Compared with conventional nursing, TXA plus progressive nursing can more effectively promote postoperative recovery of TKA patients; but the exact role of TXA and progressive nursing in TKA deserves further exploration.
