International journal of colorectal disease. 2022
Abstract
PURPOSE This meta-analysis aims to investigate the role of prophylactic clipping after endoscopic colorectal polypectomy or endoscopic mucosal resection (EMR) in prevention of delayed bleeding (DB) following polypectomy. METHODS We searched the PubMed, Embase, and Cochrane Library databases for randomized controlled trials comparing the effect of prophylactic clipping versus no clipping on DB since inception to 22nd April 2022. We then performed a meta-analysis using a random-effects model. RESULTS We included 8 studies with 5648 patients and 10,436 lesions. Prophylactic clipping did not reduce the overall risk of DB compared with no clipping (1.54% vs 2.05%; Log RR, -0.29; 95% confidence interval [CI], -0.59, 0.01; P = 0.06). In subgroup analyses, clipping significantly reduced DB rate in polyps ≥ 2 cm (Log RR, -0.63; 95% CI, -1.08, -0.18; P = 0.01), in non-pedunculated polyps (Log RR, -0.63; 95% CI, -1.01, -0.24; P = 0.00), and in large (≥ 2 cm) proximal polyps (Log RR, -0.81; 95% CI, -1.56, 0.05; P = 0.04), but not in polyps < 2 cm (Log RR, 0.01; 95% CI, -.40, 0.42; P = 0.95). CONCLUSION Prophylactic clipping does not prevent post-polypectomy bleeding after all EMR and should not be performed as a routine practice. Although prophylactic clipping may reduce DB rate following resection of large proximal polyps and non-pedunculated polyps, more high-quality studies are needed to determine the effects of factors such as polyp location, polyp morphology, antithrombotic drug use and complete or partial closure on the effectiveness of prophylactic clipping.

Abstract
BACKGROUND Tranexamic acid (TXA) has been widely used for bleeding reduction in spinal surgery. Available evidence is insufficient to inform clinical decisions making and there remains a lack of comprehensive comparisons of dose regimens and delivery routes. This study is aimed to assess and compare different strategies regarding the involvement of TXA in spinal surgery for the optimal pathway of efficacy and safety. MATERIALS AND METHODS Cochrane Library, PubMed, Embase, Scopus and CNKI were searched for the period from January 1990 to October 2021. A random-effect model was built in the Bayesian network meta-analysis. The surface under the cumulative ranking analysis (SUCRA) and clustering rank analysis was performed for ranking the effects. RESULTS The current network meta-analysis incorporated data from 33 studies with 3302 patients. Combination administration showed superior effects on reducing intraoperative bleeding (SUCRA 78.78%, MD -129.67, 95% CI [(-222.33, -40.58)]) than placebo, and was ranked as top in reducing postoperative bleeding (SUCRA 86.91%, MD -169.92, 95% CI [(-262.71, -83.52)]), changes in haemoglobin (SUCRA 97.21%, MD -1.28, 95% CI [(-1.84, -0.73)]), and perioperative blood transfusion (SUCRA 93.23%, RR 0.10, 95% CI [(0.03, 0.25)]) simultaneously, and was shown as the best effectiveness and safety (cluster-rank value for IBL and VTE: 4057.99 and for TRF and VTE: 4802.26). CONCLUSIONS Intravenous (IV) plus topical administration of TXA appears optimal in the reduction of perioperative bleeding and blood transfusion, while the local infiltration administration is not effective for blood conservation. Further studies are required to verify the current findings.
PICO Summary
Population
Patients undergoing spinal surgery (33 studies, n= 3,302).
Intervention
Tranexamic acid (TXA).
Comparison
Various comparators: low-dose intravenous (IV), high-dose IV, low-dose topical, high-dose topical, combined use (IV plus topical), oral, local infiltration, multiple IV use before and after surgery, and placebo.
Outcome
The surface under the cumulative ranking analysis (SUCRA) and clustering rank analysis was performed for ranking the effects. Combination administration showed superior effects on reducing intraoperative bleeding (SUCRA 78.78%, weighted mean difference (MD) -129.67) than placebo, and was ranked as top in reducing postoperative bleeding (SUCRA 86.91%, MD -169.92), changes in haemoglobin (SUCRA 97.21%, MD -1.28), and perioperative blood transfusion (SUCRA 93.23%) simultaneously, and was shown as the best effectiveness and safety.

Sun Y, Xiao D, Fu W, Cai W, Huang X, Li Q, Li J
Journal of clinical medicine. 2022;11(23)
Abstract
BACKGROUND Visual clarity during shoulder arthroscopy can ensure an efficient and effective performance of the procedure, and it is highly related to bleeding without a tourniquet. Tranexamic acid (TXA) is widely used in adult reconstruction procedures; however, its use in shoulder arthroscopic operations is a relatively novel topic. PURPOSE To analyze the available literature on visual clarity, blood loss, pain control, functional outcomes, and complications after the administration of tranexamic acid in shoulder arthroscopic surgery. METHODS A literature search was performed to retrieve randomized controlled trials examining the use of tranexamic acid at the time of shoulder arthroscopic surgery. The literature search included the MEDLINE, Embase, Web of Science, and Cochrane Library databases. The primary outcomes included visual clarity, blood loss, and visual analog scale scores for pain. Secondary outcomes were operative time, irrigation amount used, postoperative shoulder swelling, the need for pressure increase, mean arterial pressure (MAP), functional outcomes, postoperative adverse effects such as deep venous thrombosis, and pulmonary embolism. The outcomes were pooled to perform a meta-analysis. RESULTS Seven prospective randomized controlled trials met the inclusion criteria for analysis. All of the included studies performed arthroscopic rotator cuff repair. No significant difference in visual clarity was observed (SMD (standardized mean difference), 0.45 [95% CI(confidence interval), -0.68, 1.59]; p = 0.44) nor in pain score (MD (mean difference), -0.46 [95% CI, -0.97, 0.05]; p = 0.08) between the TXA group and the control group. Two studies found no significant difference in blood loss between the TXA group and the control group. The meta-analysis from five studies demonstrated no significant difference between the TXA and control groups in operative time (MD, -3.51 [95% CI, -15.82, 8.80]; p = 0.58) or irrigation amount used (MD, -2.53 [95% CI, -5.93, 0.87]; p = 0.14). Two trials reported different statistical results in postoperative shoulder swelling. No significant differences regarding the need for pressure increase and MAP were reported between groups. No wound complications or infections or cardiac, thrombotic, or thromboembolic complications were recorded in either group. CONCLUSION The use of intravenous or local TXA in shoulder arthroscopic surgery did not increase complications or thromboembolic events, but TXA had no obviously effect of reducing bleeding to obtain a clear visual field or pain release in patients undergoing shoulder arthroscopic surgery.

American journal of translational research. 2021;13(5):4995-5002
Abstract
OBJECTIVE To observe the efficacy of intrauterine Bakri balloon tamponade (IBBT) combined with ascending uterine artery ligation (AUAL) in the treatment of postpartum hemorrhage (PPH) due to uterine inertia after cesarean section. METHODS A total of 92 patients with PPH due to uterine inertia after cesarean section were divided into a study group (n=46) and a control group (n=46) in accordance with the random number table. The control group was treated with IBBT alone, while the study group was treated with IBBT combined with AUAL. The clinical efficacies, hemorrhage, surgical duration, hospital stay, hemorrhage rate after removal of tamponade, recurrence rate of PPH, changes in coagulation function and quality of life were compared between the two groups. RESULTS The overall response rate (ORR) in the study group was 95.65%, remarkably higher than that of 80.43% in the control group (P < 0.05). The study group had a lesser amount of hemorrhage at 2 h and 24 h after surgery, a longer surgical duration, a shorter hospital stay, and lower hemorrhage rate after removal of tamponade and recurrence rate of PPH than the control group (P < 0.05). After treatment, prothrombin time, activated partial thromboplastin time and fibrinogen in the study group were markedly higher than those in the control group (P < 0.05). Compared with those before treatment, the scores of quality of life in the two groups were elevated at 3 months after treatment (P < 0.05), and the scores of quality of life in the study group were higher than those in the control group at 3 months after treatment (P < 0.05). CONCLUSION IBBT combined with AUAL can effectively alleviate hemorrhage and improve coagulation function and quality of life of patients with PPH due to uterine inertia after cesarean section, exhibiting a definite efficacy and a high safety profile.

Journal of healthcare engineering. 2021;2021:9681129
Abstract
OBJECTIVE To evaluate the efficacy and safety of topical glucocorticoids for total hip arthroplasty by meta-analysis. METHODS A computerized search of the Cochrane Library, MEDLINE, EMBASE, and PubMed English databases, as well as Chinese Biomedical Literature Database, vipu Chinese Science and Technology Journal Database, Wanfang database, and Chinese Knowledge Net Database, was performed to include all randomized controlled trials (RCTs) regarding topical glucocorticoid therapy for postoperative bleeding after THA according to the inclusion criteria. The quality evaluation criteria of RCTs, as stated in the Cochrane Handbook for Systematic Reviews of Interventions 4.2.5, were adopted for evaluation, and the meta-analysis was performed using RevMan 5.3. RESULTS A total of 10 articles were included, including 1,112 patients: 566 in the topical glucocorticoid group and 546 in the control group. The transfusion rate was 8.43% for topical glucocorticoids and 30.05% for the control group (P < 0.001), and topical glucocorticoids reduced 317.89 ml total blood loss and 76.82 ml invisible blood loss, with statistically significant differences (P < 0.001). The amount of intraoperative blood loss was reduced by topical glucocorticoids, but the difference was not statistically significant (P=0.83), and the postoperative HB value was increased by topical glucocorticoids, although the difference was statistically significant (P < 0.001). The incidence of DVT and PE after topical glucocorticoid application (3.03%) was greater than that of the control group (2.40%), the difference was not statistically significant (P=0.54), and the incidence of infection after topical glucocorticoid application (3.03%) was greater than that of the control group (2.40%). The difference was not statistically significant (P=0.39). CONCLUSIONS Topical glucocorticoids can reduce the transfusion rate and blood loss in THA patients without increasing their risk of thrombosis.

Facial plastic surgery & aesthetic medicine. 2021
Abstract
Objective: To compare the effectiveness of tranexamic acid (TXA) in reducing blood loss and decreasing surgery duration in craniomaxillofacial surgery. Methods: The literature was searched systematically for all comparative studies of the effect of TXA on craniomaxillofacial surgery with placebo to evaluate the efficacy of TXA in craniomaxillofacial surgery. The primary outcome was intraoperative blood loss, and secondary outcomes were postoperative hematocrit, postoperative hemoglobin, and operation duration. Results: This systematic review included 16 studies consisting of 958 patients. Meta-analysis revealed that compared with the placebo group, the TXA group showed a significant reduction in intraoperative blood loss of 139.81 mL (95% confidence interval, CI: -179.66 to -99.96 mL; p < 0.01), a shortening of the maxillary surgery duration of 15.48 min (95% CI: -21.03 to -9.92 min; p < 0.01), an elevation of the postoperative hemoglobin level of 0.74 mg/dL (95% CI: 0.42 to 1.07 mg/dL; p < 0.01), and a limited effect on increasing the postoperative hematocrit level of 1.77% (95% CI: 0.17 to 3.36; p = 0.03). Conclusion: The use of TXA in craniomaxillofacial surgery can effectively reduce intraoperative blood loss, maintain elevate postoperative hemoglobin and hematocrit levels, and reduce the operation duration.

Abstract
BACKGROUND Outcomes regarding the conventional surgical and conservative treatment for the lobar intracerebral hemorrhage (ICH) have not been previously compared. The current meta-analysis was designed to review and compile the evidence regarding the management of patients with lobar intracerebral hemorrhage. METHODS Online electronic databases, including PubMed, Embase, Medline, Cochrane Library, and Google Scholar, were searched for randomized controlled trials (RCTs). Studies were selected on the basis of the inclusion and exclusion criteria. Trials with CT-confirmed lobar intracerebral hemorrhage patients of which treatment regimen was started within 72 h following the stroke were included. Low quality trials were excluded. Death or dependence was defined as primary outcome and death at the end of the follow up was the secondary outcome. RESULTS One hundred five RCTs were screened and 96 articles were excluded on the basis of abstract. Nine articles were assessed for the eligibility and 7 trials were included that involved 1,102 patients. The Odds ratio (OR) for the primary outcome was 0.80 (95% CI, 0.62-1.04, p = 0.09) and for the secondary outcome was 0.79 (95%CI, 0.60-1.03, p = 0.09). CONCLUSION Our findings suggested that surgical treatments did not significantly improve the functional outcome as compared with the conservative medical management for patients with lobar ICH.
PICO Summary
Population
Patients with lobar intracerebral haemorrhage (7 studies, n= 1,102).
Intervention
Surgical treatment, including: endoscopic surgery, open craniotomy, stereotactic aspiration, and endoscopic surgery plus stereotactic aspiration, (n= 552).
Comparison
Conservative management, including non-surgical or pharmacological (n= 550).
Outcome
The overall results showed a non-significant trend toward better prognosis in the surgical group (OR 0.80). No significant difference was observed for death at the end of the follow up between surgical and conservative medical management groups.

Comparison of efficacy and safety of different tourniquet applications in total knee arthroplasty: a network meta-analysis of randomized controlled trials
Cao Z, Guo J, Li Q, Wu J, Li Y
Annals of medicine. 2021;53(1):1816-1826
Abstract
OBJECTIVE Total knee replacement (TKA) is an effective way to treat teratogenic and disabling knee diseases such as advanced osteoarthritis. Tourniquets are often used in TKA to reduce bleeding and to get a better visualization of the surgical field, while it is related to safety concerns. We did this network meta-analysis to comprehensively compare the efficacy and safety of various tourniquet application strategies. METHOD PubMed, Embase, Cochrane Library, CNKI, and WanFang Database were systematically searched from January 1990 to May 2020. A network meta-analysis with a frequentist framework was done to assess the relative efficacy and safety by comparing seven clinical important endpoints. RESULTS 38 eligible studies that assessed 3007 participants who underwent TKA were included in this network meta-analysis. Tourniquet inflation before osteotomy then deflation after wound closure effectively reduce perioperative bleeding (WMD compared with control group -234.66, 95% CI [-409.19 to -60.13]), while shortening the operation time (WMD -8.98, 95%CI [-14.07 to -3.88]) and reducing postoperative complications, including DVT (OR -0.58, 95%CI [-1.19 to 0.03]) and minor wound complications (OR -1.38, 95%CI [-3.00 to 0.25]). No difference was found in the late postoperative knee pain and function outcomes. CONCLUSIONS Using tourniquets during the entire operation can effectively reduce blood loss, but it also can cause many safety problems, including DVTs, wound oozing, delayed healing, and serious wound complications. Tourniquet inflation before osteotomy then deflation after wound closure effectively can reduce perioperative bleeding while shortening the operation time and reducing postoperative complications, so it could be the ideal tourniquet application strategy in TKA.Key messagesThis is the first study that comprehensively compared different tourniquet application strategies to evaluate their impact on postoperative recovery following TKA, and five clinically important endpoints were assessed in this study: perioperative blood loss, operation time, postoperative pain and function, and complications.We conclude that tourniquet inflation before osteotomy then deflation after wound closure could be the ideal tourniquet application strategy in TKA.

Abstract
OBJECTIVE To investigate whether intensive blood pressure treatment is associated with less hematoma growth and better outcome in ICH patients who received intravenous nicardipine treatment within 2 hrs after onset of symptoms. METHODS A post-hoc exploratory analysis of the Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 (ATACH-2) trial was performed. This was a multicenter, international, open-label randomized clinical trial in which patients with primary ICH were allocated to intensive versus standard blood pressure treatment with nicardipine within 4.5 hours of symptom onset. We have included 913 patients with complete imaging and follow-up data in the present analysis. RESULTS Among the 913 included patients, 354 (38.7%) had intravenous nicardipine treatment initiated within 2 hours. In this subgroup of patients treated within 2 hours, the frequency of ICH expansion was significantly lower in the intensive blood pressure reduction group as compared with standard treatment group (P = 0.02). Multivariable analysis showed that ultra-early intensive blood pressure treatment was associated with a decreased risk of hematoma growth (odds ratio, 0.56; 95% CI, 0.34-0.92; P = 0.02), higher rate of functional independence (odds ratio, 2.17; 95% CI, 1.28-3.68; P = 0.004) and good outcome (OR, 1.68; 95% CI, 1.01-2.83; P = 0.048) at 90 days. Ultra-early intensive blood pressure reduction was associated with a favorable shift in modified Rankin Scale score distribution at 3 months (p = 0.04). INTERPRETATION In a subgroup of ICH patients with elevated blood pressure given intravenous nicardipine within 2 hours of symptom onset, intensive blood pressure reduction was associated with reduced hematoma growth and improved functional outcome.

Use of preoperative erythropoietin therapy to facilitate autologous blood donation in orthopedic surgery: A meta-analysis
Chang X, Li Q, Tang H
Medicine. 2020;99(2):e18577
Abstract
BACKGROUND Autologous blood transfusion helps to avoid or reduce the need for allogenic blood transfusion in patients undergoing major surgery. We examined the value of erythropoietin therapy to support preoperative autologous blood donation (PABD) in patients undergoing orthopedic surgery. METHODS For this systematic review and meta-analysis, Medline, Cochrane, EMBASE, and Google Scholar databases were searched from October 26th, 1989 until September 30th, 2017. Primary outcomes were percentages of patients able to donate ≥4 units of blood for autologous transfusion, amount of allogeneic blood transfused, changes in hematocrit and hemoglobin levels from before PABD to immediately before surgery, and adverse events. RESULTS Of 256 studies identified, 18 studies met the inclusion criteria with a total of 1914 patients (mean age 51-69 years), of whom 1153 were treated with erythropoietin. Erythropoietin was associated with a greater percentage of patients able to donate ≥4 units of blood for autologous use compared to controls (OR = 6.00, 95% CI = 3.97 to 9.09, P < .001). Patients receiving preoperative erythropoietin had significantly less of a reduction in hematocrit and hemoglobin levels from before PABD to immediately before surgery compared with controls (hematocrit: mean differences = -1.438, 95% CI = -2.14 to -0.73, P < .001; hemoglobin: mean differences = -1.426, 95% CI = -1.78 to -1.07, P < .001). No significant differences were observed in the amount of allogenic blood transfused between patients receiving erythropoietin and controls (difference in means = -0.220, 95% CI = -0.536 to 0.097, P = .174). Patients who received erythropoietin were less likely to experience dizziness than controls, but the incidence of nausea or fatigue were similar between groups. CONCLUSION Erythropoietin therapy during the PABD period results in less of a reduction in hematocrit and hemoglobin levels and an increase in the percentage of patients able to donate blood preoperatively.
