Abstract
BACKGROUND Decreased organ function and poor physical compensatory capacity in elderly patients diagnosed with spontaneous intracerebral hemorrhage (ICH) can make surgical treatment procedures challenging and risky. Minimally invasive puncture drainage (MIPD) combined with urokinase infusion therapy is a safe and feasible method of treating ICH. This study aimed to compare the treatment efficacy of MIPD conducted under local anesthesia using either 3DSlicer + Sina application or computer tomography (CT)-guided stereotactic localization of hematomas in elderly patients diagnosed with ICH. METHODS The study sample included 78 elderly patients (≥ 65 years of age) diagnosed with ICH for the first time. All patients exhibited stable vital signs and underwent surgical treatment. The study sample was randomly divided into two groups, either receiving 3DSlicer+Sina or CT-guided stereotactic assistance. The preoperative preparation time; hematoma localization accuracy rate; satisfactory hematoma puncture rate; hematoma clearance rate; postoperative rebleeding rate; Glasgow Coma Scale (GCS) score after 7 days; and modified Rankin scale (mRS) score 6 months after surgery were compared between the two groups. RESULTS No significant differences in gender, age, preoperative GCS score, preoperative hematoma volume (HV), and surgical duration were observed between the two groups (all p-values > 0.05). However, the preoperative preparation time was shorter in the group receiving 3DSlicer + Sina assistance compared to that receiving CT-guided stereotactic assistance (p-value < 0.001). Both groups exhibited significant improvement in GCS scores and reduction in HV after surgery (all p-values < 0.001). The accuracy of hematoma localization and puncture was 100% in both groups. There were no significant differences in surgical duration, postoperative hematoma clearance rate, rebleeding rate, postoperative GCS and mRS scores between the two groups (all p-values > 0.05). CONCLUSIONS A combination of 3DSlicer and Sina is effective in accurately identifying hematomas in elderly patients with ICH exhibiting stable vital signs, thus simplifying MIPD surgeries conducted under local anesthesia. This procedure may also be preferred over CT-guided stereotactic localization in clinical practice due to its ease of use and accuracy in hematoma localization.

Abstract
Objective: To study the efficacy and patient comfort of absorbable hemostatic powder after endoscopic sinus surgery (ESS). Methods: A total of 21 (17 males, 4 females) patients with an average age of 42(ranging from 18 to 65) underwent bilateral ESS for chronic rhinosinusitis(CRS) in Beijing Tongren Hospital, Capital Medical University between October 2015 and July 2019 were enrolled to compare the effect of absorbable hemostasis powder with Nasopore using an intrapatient control design. A randomized controlled trial was conducted in the left and right nasal cavities of the same patient. If hemostatic powder was applied in the experiment nasal cavity, the Nasopore was applied in the control nasal cavity. The mean preoperative sinus computed tomography (CT) score was 6.25. All patients competed for symptom diaries using a visual analog scale (VAS, score out of 10) at baseline, through 1, 7, 14 and 30 days. Outcomes including bleeding, facial pain, nasal obstruction, nasal discharges using VAS were recorded separately for both sides. Postoperative endoscopic scores were also investigated. SPSS 22 and Graphpad prism 8.0 statistical softwares were used for the analysis. Paired t-test or nonparametric test was used between the test side and the control side. The difference was statistically significant (P<0.05). Results: The bleeding score and total nasal symptom VAS scores at postoperative days (POD) 1, 7, 14 and 30 were not significantly different(t=1.341, 0.552, 0.631, 0.158, all P>0.05;t=0.944, 1.471, 1.612, 2.251, all P>0.05). There was no significant difference between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of each nasal symptom VAS scores(all P>0.05). On POD 1, 7 and 14, the packing material degeneration scores of the absorbable hemostasis powder side were significantly lower than those of the Nasopore side [(1.33±0.21)vs(2.00±0.00),(0.38±0.18) vs (1.95±0.22), 0 vs (1.80±0.13), all P<0.01]. There were significant differences between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of endoscopic scores (edema, crusting, discharges, scar, polyps and material degeneration, t=3.07, 7.00, 6.41, 2.69, all P<0.05). Conclusions: The absorbable hemostasis powder and Nasopore has similar postoperative hemostasis effect. The absorbable hemostasis powder is rapidly cleared and without negative effects on mucosal wound healing 14 days postoperatively.

Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons. 2021
Abstract
PURPOSE Leukocyte- and platelet-rich fibrin (L-PRF) and advanced-platelet-rich fibrin (A-PRF) that are derivatives of PRF (platelet-rich fibrin) accelerate wound healing and reduce postoperative sequelae after tooth extraction. This network meta-analysis aimed to investigate the effectiveness of L-PRF and A-PRF in mandibular third molar extraction and provide suggestions for alleviating postoperative symptoms and signs. METHODS A comprehensive search of the literature was conducted in PubMed, Embase, Web of Science, and SinoMed databases up to Oct 9, 2020. Three types of randomized controlled trials were included to investigate the effects of PRF derivatives after extracting mandibular third molars: A-PRF and L-PRF groups; A-PRF and control groups; L-PRF and control groups. Their relative effectiveness and ranking were assessed using network meta-analysis and the surface under the cumulative ranking curve (SUCRA) with STATA 16.0 and Revman 5.3, respectively. RESULTS Ten randomized controlled trials were included, with 307 mandibular third molar extraction patients involved. The results showed that A-PRF had the best effect among the 3 groups in improving postoperative pain on the third (SUCRA = 98.2%) and seventh (SUCRA = 88.4%) days; L-PRF promoted soft tissue healing (MD=-0.90, 95% CI [-1.40, -0.40], P = .0004) on the seventh day compared with the control. However, other comparisons showed no significant differences (P > .05). CONCLUSION The limited results confirmed that PRF derivatives only reduced some postoperative symptoms and did not prevent them all. Application of A-PRF after third molar extraction reduced postoperative pain, and L-PRF improved the degree of soft tissue healing.

Lu C, Song M, Chen J, Li C, Lin W, Ye G, Wu G, Li A, Cai Y, Wu H, et al
Journal of orthopaedic surgery and research. 2020;15(1):602
Abstract
BACKGROUND A tourniquet is a device commonly used to control massive hemorrhage during knee replacement surgery. However, the question remains whether the use of tourniquets affects the permeability of the bone cement around the knee prosthesis. Moreover, the long-term effects and stability of the knee prosthesis are still debatable. The aim of this study was to examine whether the use of a tourniquet increases the thickness of the cement mantle and affects the postoperative blood loss and pain during primary total knee arthroplasty (TKA) using meta-analysis. METHODS We searched the Cochrane Central Library, MEDLINE, Embase, PubMed, CNKI, and Wang Fang databases for randomized controlled trials (RCTs) on primary TKA, from inception to November 2019. All RCTs in primary TKA with and without a tourniquet were included. The meta-analysis was conducted using RevMan 5.2 software. RESULTS A total of eight RCTs (677 knees) were analyzed. We found no significant difference in the age and sex of the patients. The results showed that the application of tourniquet affects the thickness of the bone cement around the tibial prosthesis (WMD = 0.16, 95%CI = 0.11 to 0.21, p < 0.00001). However, in our study, there was no significant difference in postoperative blood loss between the two groups was observed (WMD = 12.07, 95%CI = - 78.63 to 102.77, p = 0.79). The use of an intraoperative tourniquet can increase the intensity of postoperative pain (WMD = 1.34, 95%, CI = 0.32 to 2.36, p = 0.01). CONCLUSIONS Tourniquet application increases the thickness of the bone cement around the prosthesis and may thus increase the stability and durability of the prosthesis after TKA. The application of an intraoperative tourniquet can increase the intensity of postoperative pain.

Thromboelastography or rotational thromboelastometry for bleeding management in adults undergoing cardiac surgery: a systematic review with meta-analysis and trial sequential analysis
Li C, Zhao Q, Yang K, Jiang L, Yu J
Journal of thoracic disease. 2019;11(4):1170-1181
Abstract
Background: Severe bleeding and massive transfusion of blood products may be associated with increased morbidity and mortality of cardiac surgery. A transfusion algorithm incorporating thromboelastography (TEG) or rotational thromboelastometry (ROTEM) can help to determine the appropriate time and target for the use of hemostatic blood products, which may thus reduce the quantity of blood loss as well as blood products transfused. Methods: We conducted meta-analysis and trial sequential analysis to evaluate the effects of TEG or ROTEM-guided transfusion algorithms vs. standard treatments for patients undergoing cardiac surgery with cardiac pulmonary bypass. Results: Nineteen studies with a total of 15,320 participants, including 13 randomized controlled trials (RCTs), were included. All-cause mortality was not reduced either in overall studies or in RCTs. Blood loss volume was reduced by 132 mL in overall studies [mean difference (MD): -132.46, 95% CI: -207.49, -57.43; I(2) =53%, P<0.01], and by 103 mL in RCTs (MD: -103.50, 95% CI: -156.52, -50.48; I(2) =0%, P<0.01). The relative risks (RRs) in RCTs were 0.89 (95% CI: 0.80-0.98; I(2) =0%, P=0.02) for red blood cells transfusion, 0.59 (95% CI: 0.42-0.82; I(2) =55%, P<0.01) for fresh frozen plasma transfusion, and 0.81 (95% CI: 0.74-0.90; I(2) =0%, P<0.01) for platelet transfusion, respectively. Trial sequential analysis of continuous data on blood loss and dichotomous outcomes on transfusion of blood products suggested the benefits of a TEG/ROTEM-guided algorithm. Conclusions: TEG or ROTEM-guided transfusion strategies may reduce blood loss volume and the transfusion rates in adult patients undergoing cardiac surgery.

International Orthopaedics. 2018;42((3):):529-535
Abstract
PURPOSE The aim of this study was to demonstrate the association between tranexamic acid (TXA)-combined application and knee flexion in the first 24 hour post-operatively that could reduce total blood loss and transfusion need in patients undergoing total knee arthroplasty (TKA), without sacrificing safety. METHODS Ninety TKA patients were divided into three groups randomly: the flexion group: the knee was in 90 degrees flexion position for the first 12 hour post-surgery and kept at 60 degrees for the next 12 hour, combined with 1 g TXA topical and 1 g TXA intravenous application. The extension group: the knee was in fully extension position post-operatively, combined with topical and intravenous TXA application. The controlled group: the knee was in fully extension position post-operatively combined with single intravenous TXA application. The primary outcomes included blood loss variables and transfusion values. The secondary outcomes included post-operative hospital stay, knee flexion degree, complication rate, and hospital charge. RESULTS The total blood loss and transfusion needs in the flexion group were significantly reduced in comparison with that in the extension group and controlled group. The post-operative knee flexion motion was significant higher in the flexion group than the other two groups. There was no difference among the three groups with regard to the rates of complications. CONCLUSIONS Keeping the knee in flexion position combined with topical and intravenous TXA application in patients undergoing primary unilateral TKA significantly reduced post-operative bleeding and the transfusion rate compared with what was found after treatment with extension knee position or single intravenous TXA application. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
INTRODUCTION The purpose of this study was to investigate the benefits of three different post-operative limb positions in primary total knee arthroplasty (TKA). METHODS The trial was a single-surgeon, randomized, controlled trial, and 135 patients following primary TKA were randomized into three groups: group A (45 patients who were treated with the hip fixed at 50 degrees and knee flexed at 90 degrees for 6 hours post-operatively), group B (45 patients who were treated with the hip elevated at 30 degrees and knee flexed at 45 degrees for 6 hours post-operatively), and group C (45 patients in whom the affected knee was fully extended after surgery). Tranexamic acid was used in all patients. RESULTS The total blood loss and hidden blood loss in group A (921 +/- 209 mL, 597 +/- 213 mL) were significantly less than in groups B (1125 +/- 222 mL, 784 +/- 229 mL) and C (1326 +/- 291 mL, 915 +/- 301 mL) and less in group B compared with group C. The drain volume in groups A (158 +/- 35 mL) and B (174 +/- 45 mL) was significantly lower than in group C (249 +/- 31 mL). The maximum haemoglobin drop in group A (3.1 +/- 0.5 g/dL) was statistically significantly less than in groups B (3.6 +/- 0.7 g/dL) and C (4.3 +/- 0.4 g/dL). The range of motion (ROM) in groups A (102 +/- 3 degrees , 105 +/- 2 degrees ) and B (100 +/- 3 degrees , 104 +/- 2 degrees ) was significantly better than in group C (98 +/- 3 degrees , 102 +/- 2 degrees ) at the time of discharge and one month after surgery; it was also significantly less for group A (104.9 +/- 2.1%, 108.0 +/- 2.4%) compared with groups B (106.7 +/- 3.1%, 108.3 +/- 2.7%) and C (108.4 +/- 3.2%, 110.6 +/- 3.0%) with post-operative knee swelling. No differences in transfusion requirements and complications were observed among the three groups. CONCLUSIONS The affected knee flexion position was superior to the use of a fully extended position for blood management, but it only contributed to better early functional recovery up to three months post-operatively in TKA. In addition, by fixing the affected knee at a high flexion position of 90 degrees , patients could achieve less blood loss, lower knee swelling, and better early results for ROM and patient satisfaction than the other two groups.

Medicine. 2017;96((7)):e5804.
Abstract
BACKGROUND Drainage and tranexamic acid (TXA) have been widely used in total knee arthroplasty (TKA). However, it remains unclear whether it is necessary to clamp the drain after minimally invasive TKA (MIS-TKA) when TXA is used. We therefore conducted a randomized controlled trial to compare the effects of clamping versus not clamping drainage following MIS-TKA in patients in whom TXA was used. METHODS From January 2015 to December 2015, 121 patients undergoing unilateral primary MIS-TKA were enrolled and randomly divided into 2 groups. In the clamping group (N = 60), drainage was clamped for the 1st 4 postoperative hours. In the nonclamping group (N = 61), drainage was not clamped. All patients underwent a minimidvastus approach and received 10 mg/kg TXA intravenously before tourniquet deflation. We recorded the total blood loss, drainage volume, and transfusion requirements in the postoperative period. We also measured the hemoglobin (Hb) and hematocrit (Hct) levels on postoperative days 1, 3, and 5. Other factors, including range of motion (ROM), visual analog scale (VAS), and occurrence of wound-related complications, deep vein thrombosis (DVT), and pulmonary embolism (PE) were recorded at the time of discharge and 1 and 6 months postoperatively. No statistically significant differences were found between the 2 groups with regard to age, gender, weight, BMI, preoperative Hb and Hct levels, preoperative ROM, VAS, duration of surgery, anesthesia method, and the American Society of Anesthesiologists classification. RESULTS The clamping group experienced better drainage volume results than the nonclamping group (P < 0.001). There were no statistically significant differences in TBL and transfusion requirements (P = 0.105 and 0.276, respectively); Hb and Hct levels on postoperative days 1, 3, and 5 were similar between the 2 groups. No significant differences were found for ROM, VAS, DVT, PE, wound-related complications, and hospital length of stay in the postoperative follow-up. CONCLUSION Based on our findings, clamping drainage is unnecessary after routine MIS-TKA using TXA.

Wu Y, Yang T, Zeng Y, Si H, Li C, Shen B
Blood Coagulation & Fibrinolysis : an International Journal in Haemostasis and Thrombosis. 2017;28((7):):501-508
Abstract
: The aim of this meta-analysis is to assess the effectiveness and safety of intravenous application tranexamic acid (TXA) in primary simultaneous bilateral total knee arthroplasty (TKA). We searched electronic databases including PubMed, Embase, the Web of Science, the Cochrane Library and the Google Scholar, for published studies involving the intravenous application TXA in primary simultaneous bilateral TKA. All randomized controlled trials were included. The focus of the meta-analysis was on the outcomes of total blood loss, drainage volume, transfusion requirements and deep venous thrombosis (DVT) and/or pulmonary embolism. The relevant data were analyzed using RevMan 5.2. Six high randomized controlled trials were included, with a total sample size of 394 patients. The intravenous application of TXA significantly reduced total blood loss [95% confidence interval (CI), -519.52 to -126.40; P = 0.001], drainage volume (95% CI, -551.76 to -138.57; P = 0.001) and transfusion requirements (risk ratio, 0.38; 95% CI, 0.21-0.68; P = 0.001) compared with the control group. In addition, there were no significant differences in the rate of DVT (P = 1.00) and/or pulmonary embolism between the two groups. Based on the current evidence, this meta-analysis showed that intravenous application of TXA is effective and a well tolerated treatment to reduce total blood loss, drainage volume and transfusion requirements without increasing the risk of DVT and/or pulmonary embolism in primary simultaneous bilateral TKA.

Effect of different postoperative limb positions on blood loss and range of motion in total knee arthroplasty: An updated meta-analysis of randomized controlled trials
Wu Y, Yang T, Zeng Y, Si H, Li C, Shen B
International Journal of Surgery (London, England). 2016;37:15-23
Abstract
BACKGROUND Postoperative limb positioning has been reported to be an efficient and simple way to reduce blood loss and improve range of motion following total knee arthroplasty (TKA). This meta-analysis was designed to compare the effectiveness of two different limb positions in primary TKA. MATERIALS AND METHODS A meta-analysis of the PubMed, CENTRAL, Web of Science, EMBASE and Google Search Engine electronic databases was performed. In this meta-analysis, two postoperative limb positions were considered: mild-flexion (flexion less than 60 degrees ) and high-flexion (flexion at 60 degrees or more). The subgroups were analysed using RevMan 5.3. RESULTS Nine RCTs were included with a total sample size of 913 patients. The mild- and high-flexion positions significantly reduced postoperative total blood loss (P = 0.04 and P = 0.01; respectively). Subgroup analysis indicated that knee flexion significantly reduced hidden blood loss when the knee was fixed in mild-flexion (P = 0.0004) and significantly reduced transfusion requirements (P = 0.03) and improved range of motion (ROM) (P < 0.00001) when the knee was fixed in high-flexion. However, the rates of wound-related infection, deep venous thrombosis (DVT) and pulmonary embolism (PE) did not significantly differ between the two flexion groups. CONCLUSION This meta-analysis suggests that mild- and high-flexion positions have similar efficacy in reducing total blood loss. In addition, subgroup analysis indicates that the mild-flexion position is superior in decreasing hidden blood loss compared with high-flexion; the high-flexion position is superior to mild-flexion in reducing transfusion requirements and improving postoperative ROM. Thus, the use of the high-flexion position is a viable option to reduce blood loss in patients following primary TKA without increasing the risk of wound-related infection, DVT or PE.
