Background: Spinal surgeries are often accompanied by significant blood loss both intraoperatively and postoperatively. Excessive blood loss caused by surgery may lead to several harmful medical consequences. Tranexamic acid (TXA) is a kind of antifibrinolytic agent that has been widely used in spinal surgery. Currently, it is commonly accepted that intravenous TXA (ivTXA) can reduce blood loss in spinal fusion surgeries. Compared with ivTXA, topical TXA (tTXA) seems to be much easier to administer. This advantage provides a maximum concentration of TXA at the hemorrhagic site with little to no TXA entering the circulation. Objective: To evaluate the effect of tTXA on blood loss during and after spinal surgery via a comprehensive meta-analysis of the published data in randomized controlled trials (RCTs) and other comparative cohort studies. Methods: A comprehensive search of PubMed, EMBASE, the Web of Science, and the Cochrane Central Register of Controlled Trials were performed for RCTs and other comparative cohort studies on the effect of tTXA on blood loss during and after spinal surgery. The outcomes were total blood loss, hidden blood loss, intraoperative blood loss, total postoperative drainage volume, drainage tube duration postoperatively, drainage volume and drainage of blood content at postoperative day (POD) 1 and POD2, length of hospital stay, number of patients who received a blood transfusion, serum HB level at POD1, operative timespan, side effects, and complications. The final search was performed in October 2020. We followed the PRISMA guideline, and the registration number is INPLASY202160028. Results: In total, six studies with 481 patients were included. tTXA treatment, compared with the control conditions, can significantly reduce the total blood loss, hidden blood loss, total postoperative drainage volume, and several patients receiving blood transfusions; reduce the drainage volume and drainage of blood content at POD1; shorten the drainage tube duration postoperatively and length of hospital stay, and enhance the serum HB level at POD1 for spinal surgery. tTXA treatment did not significantly influence the intraoperative blood loss, drainage volume, or drainage of blood content at POD2 or the operative duration. Conclusion: Compared with control conditions, tTXA has high efficacy in reducing blood loss, and drainage volume enable quick rehabilitation and has a relatively high level of safety in spinal surgery.

Abstract Background Although intravenous tranexamic acid administration (ivTXA) has prevailed in clinical antifibrinolytic treatment, whether it increases thromboembolic risks has remained controversial. As a potent alternative to ivTXA, topical use of TXA (tTXA) has been successfully applied to attenuate blood loss in various surgical fields while minimizing systemic exposure to TXA. This meta-analysis was conducted to gather scientific evidence for tTXA efficacy on reducing postoperative drainage, blood loss, and the length of hospital stay in spine surgeries. Objectives To examine whether topical use of TXA (tTXA) reduces postoperative drainage output and duration, hidden blood loss, hemoglobin level drop, hospital stay, and adverse event rate, we reviewed both randomized and non-randomized controlled trials that assessed the aforementioned efficacies of tTXA compared with placebo in patients undergoing cervical, thoracic, or lumbar spinal surgeries. Methods An exhaustive literature search was conducted in MEDLINE and EMBASE databases from January 2000 through March 2020. Measurable outcomes were pooled using Review Manager (RevMan) version 5.0 in a meta-analysis. Results Significantly reduced postoperative drainage output (weighted mean difference [WMD]= − 160.62 ml, 95% confidence interval (95% CI) [− 203.41, − 117.83]; p < .00001) and duration (WMD= − 0.75 days, 95% CI [− 1.09, − 0.40]; p < .0001), perioperative hidden blood loss (WMD= − 91.18ml, 95% CI [− 121.42, − 60.94]; p < .00001), and length of hospital stay (WMD= − 1.32 days, 95% CI [− 1.90, − 0.74]; p < .00001) were observed in tTXA group. Pooled effect for Hb level drop with tTXA vs placebo crossed the equivalent line by a mere 0.05 g/dL, with the predominant distribution of 95% confidence interval (CI) favoring tTXA use. Conclusions With the most comprehensive literature inclusion up to the present, this meta-analysis suggests that tTXA use in spinal surgeries significantly reduces postoperative drainage, hidden blood loss, and hospital stay duration. The pooled effect also suggests that tTXA appears more effective than placebo in preserving postoperative Hb level, which needs further validation by future studies.

To analyze the dynamic variation in perioperative hidden blood loss in patients with intertrochanteric fracture. From January to December 2017, 79 patients with intertrochanteric fracture were treated with proximal femoral nail antirotation. Serial complete blood count assays were performed consecutively in the 3 days after admission, on the day of surgery, and 7 days postoperatively. Blood loss during surgery, postoperative drainage, and perioperative blood transfusion volumes were recorded. Dynamic changes in hemoglobin (Hb) prior to surgery were recorded and compared between males and females. Patients were divided into the no blood transfusion group, the 400-mL blood transfusion group, and the 800-mL blood transfusion group depending on the volume of perioperative blood transfusion. Total and hidden blood loss were separately calculated according to the Gross equation. Lowest mean Hb values occurred on day 2 after admission among men (104.8 g/L) and on day 3 after admission among women (98.6 g/L). The average Hb decrease was 11.4 g/L, 11.8 g/L, and 8.9 g/L in the no, 400-mL, and 800-mL blood transfusion groups, respectively. The lowest Hb value occurred on postoperative day 2. Hemoglobin increased on postoperative day 3 and stabilized by day 6. In the no blood transfusion group, the average total blood loss was 406.0 ± 255.6 mL, 628.3 ± 267.2 mL, and 759.7 ± 322.1 mL in the no blood transfusion, 400-mL blood transfusion, and 800-mL blood transfusion groups, respectively, and hidden blood loss was 326.0 ± 246.6 mL, 512.1 ± 247.3 mL, and 596.1 ± 306.9 mL, respectively. Perioperative hidden blood loss occurred prior to surgery for intertrochanteric fracture and ended on postoperative day 2.

Background. Laparoscopy has been widely applied in gastrointestinal surgery, with benefits such as less intraoperative blood loss, faster recovery, and shorter length of hospital stay. However, it remains controversial if laparoscopic major gastrointestinal surgery could be conducted for patients with chronic obstructive pulmonary disease (COPD) which was traditionally considered as an important risk factor for postoperative pulmonary complications. The present study was conducted to review and assess the safety and feasibility of laparoscopic major abdominal surgery for patient with COPD. Materials and Methods. Databases including PubMed, EmBase, Cochrane Library, and Wan-fang were searched for all years up to Jul 1, 2018. Studies comparing perioperative results for COPD patients undergoing major gastrointestinal surgery between laparoscopic and open approaches were enrolled. Results. Laparoscopic approach was associated with less intraoperative blood loss (MD = -174.03; 95% CI: −232.16 to -115.91, P < 0.00001; P < 0.00001, I2=93% for heterogeneity) and shorter length of hospital stay (MD = -3.30; 95% CI: −3.75 to -2.86, P < 0.00001; P = 0.99, I2=0% for heterogeneity). As for pulmonary complications, laparoscopic approach was associated with lower overall pulmonary complications rate (OR = 0.58; 95% CI: 0.48 to 0.71, P < 0.00001; P = 0.42, I2=0% for heterogeneity) and lower postoperative pneumonia rate (OR = 0.53; 95% CI: 0.41 to 0.67, P < 0.00001; P = 0.57, I2=0% for heterogeneity). Moreover, laparoscopic approach was associated with lower wound infection (OR = 0.51; 95% CI: 0.42 to 0.63, P < 0.00001; P = 0.99, I2=0% for heterogeneity) and abdominal abscess rates (OR = 0.59; 95% CI: 0.44 to 0.79, P < 0.0004; P = 0.24, I2=30% for heterogeneity). Conclusions. Laparoscopic major gastrointestinal surgery for properly selected COPD patient was safe and feasible, with shorter term benefits.

Introduction: To investigate the effect of tranexamic acid on the removal time of drainage tube in the first unilateral total knee arthroplasty. Hypotheses: The timing of removing the drinage system can be changed when using TXA. Methods: From June 2017 to December 2018, 182 patients (42 males and 140 females) who planned to undergo primary unilateral total knee replacement were included.Age (68.1±7.1) years (60-76 years).According to the random number table method, it was divided into four groups: 45 cases of Tranexamic acid group 1 (TXA1), 46 cases of Tranexamic acid group 2 (TXA2), 46 cases of Tranexamic acid group 3 (TXA3) and None Tranexamic acid group (NTXA).TXA1-3 group intraoperative intravenous infusion combined with local application of tranexamic acid;NTXA group was locally perfused in the joint cavity with 100ml normal saline only after surgery.Differences in drainage volume, total blood loss, invisible blood loss, degree of postoperative joint swelling, Hospital for special surgery (HSS) and visual analogue scale (VAS) of pain were compared among the four groups. Results: The postoperative drainage volume of TXA1˜3 groups was 85.5±34.3ml, 189.4±72.3ml and 215.3±93.4ml, respectively, which was less than that of the non-tranexamic acid group (351.3±113.5ml). The overall difference was statistically significant (F=11.5,P=0.005). The postoperative drainage volume of tranexamic acid 1 group was less than that of tranexamic acid 2 and 3 groups.The total postoperative blood loss was 699.0±255.7ml, 710.4±296.1ml, and 715.8±248.2ml in the tranexamic acid 1-3 groups, respectively, which was less than 1130.5±354.2ml in the non-tranexamic acid group, and the overall difference was statistically significant (F=13.1,P=0.001).On the 4th day after the operation, the knee swelling degree of the tranexamic acid 1- 3 groups was 1.25±0.07, 1.13±0.12, and 1.12±0.13, respectively, which were smaller than that of the non-tranexamic acid group (1.43±0.22), and the overall difference was statistically significant (F=8.23, P=0.015).There were 2 cases of positive bacterial culture in non-tranexamic acid group and tranexamic acid group.There were 3 cases of hematoma in the non-tranexamic acid group,and 1 case of delayed wound healing. Conclusion: The application of tranexamic acid after TKA can reduce postoperative drainage volume, latent blood loss and total blood loss.The removal of the drainage tube 18h after the operation can not only fully drain,relieve pain, promote the recovery of knee joint function, but also effectively reduce the risk of infection caused by the drainage tube.

The use of tranexamic acid (TXA) for reducing blood loss in intertrochanteric fracture (IF) surgery remains controversial. We therefore performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy and safety of TXA in reducing transfusion requirements and blood loss for IF surgery. Databases, including PubMED, Cochrane, and Embase, were searched for RCTs that were published before February 2018 and that addressed the efficacy and safety of TXA in patients who underwent IF surgery. A total of 746 patients from 7 RCTs were subjected to meta-analysis. The results showed that TXA group had reduced surgical blood loss (weighted mean difference [WMD] = −37.24, 95% confidence interval [CI]: −48.70 to −25.77, P <.00001), reduced total blood loss (WMD = −199.08, 95% CI: −305.16 to −93.01, P = .0002), higher postoperative hemoglobin (WMD = 0.46, 95% CI: 0.12 to 0.79, P = .007), and hematocrit levels (WMD = 1.55, 95% CI: 0.64 to 2.47, P = .008) compared to control group, while no significant differences were found in transfusion rates (relative risk [RR] = 0.75, 95% CI: 0.50 to 1.11, P = .15), postoperative drainage (WMD = −38.82, 95% CI: −86.87 to 9.22, P = .11), and thromboembolic events (RR = 0.94, 95% CI: 0.41 to 2.19, P = .89). In patients undergoing IF surgery, the administration of TXA significantly reduced surgical blood loss and total blood loss, while it had no significant effect on transfusion rate, postoperative drainage, and the risk of thromboembolic events. Nevertheless, due to the variations in the included studies, additional RCTs are required to further validate these conclusions.

BACKGROUND: Numerous studies on the comparison of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and open-transforaminal lumbar interbody fusion (O-TLIF) for the treatment of lumbar disc herniation (LDH) have been published, but there is no clear conclusion. OBJECTIVE: The aim of this study was to evaluate the efficacy of MIS-TLIF compared with O-TLIF in the treatment of LDH in the Chinese population by meta-analysis. METHODS: Studies on the treatment of LDH by MIS-TLIF versus O-TLIF were searched in Pubmed, Web of Science, Medline, Embase, CNKI, VIP and China Wanfang databases from the establishment of the databases to January 2020. The meta-analysis was used to analyze the pooled operation time, intraoperative blood loss, postoperative drainage, postoperative ground movement time, Waist and leg Visual Analogue Scale (VAS) score, Oswestry Disability Index (ODI) score and Japanese orthopaedic association (JOA) score. Mean difference (MD) and standard mean difference (SMD) were used as the effect size. RESULTS: Eleven studies with 1132 patients were included. The results showed that MIS-TLIF compared with O-TLIF, MD =-133.82 (95% CI: -167.10 ∼-100.53, P< 0.05) in intraoperative blood loss, MD =-114.43 (95% CI: -141.12 ∼-87.84, P< 0.05) in postoperative drainage, MD =-3.30 (95% CI: -4.31 ∼-2.28, P< 0.05) in postoperative ground movement time, SMD =-1.44 (95% CI: -2.63 ∼-0.34, P< 0.05) in postoperative low back pain VAS score, SMD = 0.41 (95% CI: 0.15 ∼ 0.66, P< 0.05) in postoperative JOA score, MD = 4.12 (95% CI: -11.64 ∼ 19.87, P> 0.05) in the average operation time, SMD =-0.00 (95% CI: -0.36 ∼ 0.36, P> 0.05) in leg pain VAS score, and SMD =-0.59 (95% CI: -1.22 ∼ 0.03, P> 0.05) in ODI score. CONCLUSION: MIS-TLIF was superior to O-TLIF in the treatment of LDH, especially in the intraoperative blood loss, postoperative drainage, postoperative ground movement time and low back pain in the Chinese population.

Abstract Aim Basal ganglia haemorrhage (BGH) is the most common type of intracerebral bleed with high morbidity and mortality rate. The efficacy between craniotomy and endoscopic approach in BGH is still debatable and advancement in minimally invasive technique has made endoscopic approach the preferred option. The aim of this systematic review and meta-analysis was to evaluate the outcomes of craniotomy and endoscopic approach in BGH. Method Databases of PubMed, EMBASE, MEDLINE and CENTRAL were systematically searched from its inception until December 2020. All randomized clinical trials and observational studies comparing craniotomy versus endoscopic approach in BGH were included. Results Twelve studies enrolling 1297 patients (craniotomy:675, endoscopy:632) were included for qualitative and quantitative analysis. Endoscopic approach was associated with significantly lower postoperative mortality (OR:0.35, P &lt; 0.00001), higher haematoma evacuation rate (MD:4.95, P = 0.0002), shorter operative time (MD:-117.03, P &lt; 0.00001), lesser intraoperative blood loss (MD:-328.47, P &lt; 0.00001), higher postoperative Glasgow Coma Scale (GCS) (MD:1.14, P = 0.01), higher postoperative Glasgow Outcome Scale (GOS) (MD:0.44, P = 0.05), shorter length of hospital stay (MD:-2.90, P &lt; 0.00001), lower complication rate (OR:0.30, P = 0.0004), lower infection rate (OR:0.29, P &lt; 0.00001) and lower modified Rankin Scale (mRS) (MD:-0.57, P = 0.004) compared to craniotomy. No significant difference was detected in reoperation, intracranial infection, re-bleeding. Conclusions The best available evidence suggest that endoscopic approach has better outcomes in mortality rate, operative time, haematoma evacuation rate, intraoperative blood loss, length of hospital stay, mRS, postoperative GCS and GOS compared with craniotomy in the management of BGH. However, there is a need for high quality randomised controlled trials with large sample size for definite conclusions.

Abstract Background The prevalence of osteoporosis in patients who undergo a primary total knee arthroplasty (TKA) is increasing. Low bone mineral density (BMD) is related to unfavorable outcomes following TKA such as migration of uncemented tibial components. Postoperative blood loss in TKA is an important complication. Non-modifying predicting factors for postoperative blood loss in patients undergoing primary TKA need further elucidation. Studies on the association between BMD and blood loss after TKA are limited. We aimed to demonstrate the relationship between BMD and postoperative drainage volume following primary TKA. Methods A cross-sectional study was conducted between January 2014 and August 2020. A total of 119 primary varus osteoarthritis knees with BMD results were included in the study. Patients with secondary causes of osteoporosis were excluded. Results The median postoperative drainage volume of participants in the normal total hip BMD group and the normal trochanter BMD group was higher than that of patients in the low total hip BMD group and the low trochanter BMD group (285.0 ml vs 230.0 ml, P = 0.003; 282.5 ml vs 240.0 ml, P = 0.013, respectively). Multivariate regression analyses showed that operative time, spinal anesthesia, and normal total hip BMD status were significant predictive factors associated with increased postoperative drainage volume (P = 0.014, 0.022, and 0.013, respectively). No association was identified between the lumbar spine BMD status and postoperative drainage volume. Conclusions The relationship between BMD and postoperative blood loss in primary TKA was identified in this study. Normal total hip BMD was found to be associated with an increased postoperative drainage volume after primary TKA compared with low BMD.

Background Previous studies and meta analyses have led to incongruent and incomplete results respectively when total intravenous anesthesia (TIVA) and inhalational anesthesia (IA) are compared in endoscopic sinus surgeries in regards to intraoperative bleeding and visibility. Objective To perform a more comprehensive meta-analysis on randomized controlled trial (RCTs) comparing TIVA with IA in endoscopic sinus surgery to evaluate their effects on intraoperative bleeding and visibility. Methods A systematic review and meta-analysis of studies comparing TIVA and IA in endoscopic sinus surgery for chronic rhinosinusitis was completed in May 2020. Utilizing databases, articles were systematically screened for analysis and 19 studies met our inclusion criteria. The primary outcome included intraoperative visibility scores combining Boezaart, Wormald and Visual Analogue Scale (VAS). Secondary outcomes included rate of blood loss (mL/kg/min), estimated total blood loss (mL), Boezaart, Wormald scores, VAS, heart rate, and mean arterial pressure (MAP). Results 19 RCTs with 1,010 patients were analyzed. TIVA had a significantly lower intraoperative bleeding score indicating better endoscopic visibility (Boezaart, VAS, and Wormald) than IA (−0.514, p = 0.020). IA had a significantly higher average rate of blood loss than TIVA by 0.563 mL/kg/min (p = 0.016). Estimated total blood loss was significantly lower in TIVA than IA (−0.853 mL, p = 0.002). There were no significant differences between TIVA and IA in the mean heart rate (−0.225, p = 0.63) and MAP values (−0.126, p = 0.634). The subgroup analyses revealed no significant difference between TIVA and IA when remifentanil was not utilized and whenever desflurane was the IA agent. Conclusion TIVA seemed to have superior intraoperative visibility scores and blood loss during endoscopic sinus surgery when compared to IA. However, the results are not consistent when stratifying the results based on the use of remifentanil and different inhaled anesthetics. Therefore, the conclusion cannot be made that one approach is superior to the other.
