Abstract
BACKGROUND Reported bleeding incidences following central venous catheter (CVC) placement highly depend on methods of bleeding assessment. To determine the direction and magnitude of the bias associated with retrospective data collection, we used data from the PACER randomized controlled trial and a previous retrospective cohort study. STUDY DESIGN AND METHODS A patient-level comparison of CVC-related bleeding severity was made among (1) the prospectively collected clinical bleeding assessment of the PACER trial, (2) centralized assessment of CVC insertion site photographs, and (3) retrospective chart review. Interrater reliability for photographic bleeding assessment and retrospective chart review was assessed using Cohen's κ. The magnitude of underreporting of both methods compared to prospective clinical bleeding assessment at different cutoff points of clinically relevant bleeding was assessed using McNemar's test. RESULTS Interrater reliability was acceptable for both methods (κ = 0.583 and κ = 0.481 for photographic assessment and retrospective chart review, respectively). Photographic bleeding assessment led to significant underreporting of bleeding complications at all cutoff points. Retrospective chart review led to significant underreporting of minor bleeding complications, with an odds ratio (95% CI) of 0.17 (0.044-0.51) for the cutoff point grade 1 (i.e., self-limiting or requiring at most 20 min of manual compression) or higher. There was no significant underreporting of major bleeding complications with retrospective chart review. DISCUSSION Centralized photographic bleeding assessment and retrospective chart review lead to biased bleeding assessment compared to prospective clinical bleeding assessment.

Abstract
INTRODUCTION Tranexamic acid has been widely used in plastic surgery. However, its efficacy has yet to be fully established. This meta-analysis aimed to determine its effectiveness in aesthetic plastic surgery. METHODS Following PRISMA guidelines, we conducted a meta-analysis of prospective randomised clinical trials that compared the effects of topical or systematic administration of tranexamic acid versus the control group in aesthetic plastic surgeries. The study was registered on the International Register of Systematic Reviews (PROSPERO) and is available online ( www.crd.york.uk/prospero , CRD42023492585). RESULTS Eleven studies encompassing 960 patients were included for the synthesis after critical evaluation. Systematic (MD - 18.05, 95% Cl, - 22.01, - 14.09, p < 0.00001) and topical (MD - 74.93, 95% Cl, - 88.79, - 61.07, p < 0.00001) administration of tranexamic acid reduced total blood loss. Topical tranexamic acid reduced drainage output (p < 0.0006). CONCLUSION Tranexamic acid reduced blood loss in aesthetic plastic surgery. More strictly defined RCTs, using high-quality methodology, are needed to evaluate the advantages and disadvantages of tranexamic acid in aesthetic plastic surgery.

Determination of Whole Blood Loss From Minimally Invasive Myomectomy Using a Standardized Formula: A Pilot Study. J Minim Invasive Gynecol 2024; 31:488-495.

Abstract
STUDY OBJECTIVE To determine the median perioperative blood loss (PBL) during minimally invasive surgical (MIS) myomectomy. DESIGN Prospective pilot study. SETTING Large academic teaching hospital. PATIENTS Thirty-one patients underwent laparoscopic or robotic myomectomy and completed a postoperative complete blood count (CBC) from November 2020 to August 2022. Patients had to have at least one fibroid greater than or equal to 3 cm on preoperative imaging. INTERVENTIONS A CBC was collected preoperatively within 7 days of surgery. Estimated blood loss (EBL) was determined by the surgeon intraoperatively. A repeat CBC was drawn between postoperative days 2 through 4. PBL was calculated using the equation PBL = (patient weight in kg × 65 cc/kg) × (preoperative hematocrit - postoperative hematocrit)/preoperative hematocrit. MEASUREMENTS AND MAIN RESULTS Median PBL (536.3 cc [270.0, 909.3]) was greater than median EBL (200.0 cc [75.0, 500.0]). PBL ranged from a net gain of 191.5 cc to net loss of 2362.5 cc. Median size of the largest fibroid on preoperative imaging was 8.8 cm (6.6, 11.5), and median weight of fibroids removed was 321 g (115, 519). About half of patients (51.6%) had one fibroid removed, and 48.4% had 2 or more fibroids removed. Five patients were converted to laparotomy, 4 from robotic approaches. Two patients required a blood transfusion. CONCLUSION Calculated PBL was greater than intraoperative EBL. This suggests there is continued blood loss post myometrial bed closure. Blood loss should be evaluated both during and after myomectomy, as intraoperative EBL underestimates total PBL.

Abstract
ABSTRACT Introduction: Accurate and real-time monitoring of surgical blood loss is essential for ensuring intraoperative safety. However, there is currently no standard way to assess the amount of blood lost in patients during surgery. This study aims to evaluate the accuracy and precision of a new automatic intraoperative blood loss monitor, which can measure both free blood volume and blood content in sponges in real time. Methods: The monitor uses an integrated photoelectric probe to gauge hemoglobin levels in both free blood and blood taken from surgical sponges. These data, combined with initial hemoglobin levels, are processed using specific calculations to determine blood volume. We created 127 diverse free blood samples and 160 blood-containing sponge samples by using fresh pig blood and physiological saline. The monitor then measured these samples. We subsequently compared its measurements with actual values acquired through physical measurements, detecting both agreement and measurement errors. Repeated measurements were performed to calculate the coefficient of variation, thereby evaluating the monitor's precision. Results: The estimated blood loss percentage error of the monitor was 5.2% for free blood, -5.7% for small sponge, -6.3% for medium sponge, and -6.6% for large sponge. The coefficient of variation of free blood with different hemoglobin concentrations measured by the monitor was less than 10%. Bland-Altman analysis showed that the limits of agreement between the monitor and the reference method were all within the acceptable clinical range. Conclusion: The new automatic intraoperative blood loss monitor is an accurate and reliable device for monitoring both free blood and surgical sponge blood, and shows high performance under various clinical simulation conditions.

Int J Obstet Anesth 2024; 58:103957. [PMID: 38071128 DOI: 10.1016/j.ijoa.2023.103957] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 10/05/2023] [Accepted: 11/15/2023] [Indexed: 05/07/2024]
Abstract
BACKGROUND The Shock Index (SI), defined as heart rate divided by systolic blood pressure, is reportedly an early surrogate indicator for postpartum hemorrhage (PPH). However, most previous studies have used clinical data of women who delivered vaginally. Therefore, we aimed to evaluate the SI pattern during cesarean delivery and determine its usefulness in detecting PPH. METHODS This was a single-center retrospective study using the clinical data of women (n = 331) who underwent cesarean delivery under spinal anesthesia at term between 2018 and 2021. We assessed the SI pattern stratified by total blood loss and evaluated the predictive performance of each vital sign in detecting PPH (total blood loss ≥1000 mL) based on the area under the receiver operating characteristic curve (AUROC). RESULTS At 10-15 min after delivery, the mean SI peaked between 0.84 and 0.90 and then decreased to a level between 0.72 and 0.77, which was similar to that upon entering the operating room. Among 331 women, 91 (27.5%) were diagnosed with PPH. There was no correlation between SI and total blood loss (rs = 0.02). The SI had low ability to detect PPH (AUROC 0.54, 95% confidence interval 0.47 to 0.61), which was similar to other vital signs (AUROCs 0.53-0.56). CONCLUSION We determined the pattern of SI during cesarean delivery. We found no correlation between SI and total blood loss. Unlike in vaginal delivery, the prognostic accuracy of SI for PPH detection in cesarean delivery was low.

Abstract
1. OBJECTIVE To perform a network meta-analysis to specify the route of administration that maximises the effectiveness of each of the available prophylactic uterotonics without increasing the risk for side effects. 2. DATA SOURCES Literature searches on 12th September 2022 included: CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. The reference lists of the retrieved study records were also searched. 3. STUDY ELIGIBILITY CRITERIA Population: Randomized controlled trials involving women in the third stage of labour after a vaginal or caesarean delivery in hospital or community settings. INTERVENTIONS Systemically administered prophylactic uterotonics of any route and dose for primary postpartum hemorrhage prevention. Comparison: Any other prophylactic uterotonic, or a different route or dose of a given uterotonic, or placebo, or no treatment. Outcomes (primary): postpartum hemorrhage ≥ 500 mL and ≥ 1000 mL. 4. STUDY APPRAISAL AND SYNTHESIS METHODS Risk of bias and trustworthiness assessments were performed, according to Cochrane's guidance. Direct, indirect and network meta-analyses were conducted, and results were summarized either as risk ratio or mean difference with 95% confidence intervals for dichotomous and continuous outcomes, respectively. The certainty of generated evidence was assessed according to the GRADE approach. Cumulative probabilities were calculated and the surface under the cumulative ranking curve was used to create a ranking of the available drugs. 5. RESULTS One hundred eighty-one studies involving 122,867 randomised women were included. Most studies were conducted in hospital settings in lower-middle income countries and involved women delivering vaginally. When compared with intramuscular oxytocin, carbetocin (RR 0.58, 95 % CI 0.40-0.84) and oxytocin (RR 0.75, 95 % CI 0.59-0.97) by an intravenous bolus, and intramuscular ergometrine plus oxytocin combination (RR 0.71, 95 % CI 0.56-0.91) are probably more effective in preventing primary postpartum hemorrhage. Intramuscularly administered oxytocin and carbetocin by an intravenous bolus have a favourable side effects profile. 6. CONCLUSIONS Generated evidence was generally moderate and global inconsistency was low. Carbetocin and oxytocin by an intravenous bolus, and intramuscular ergometrine plus oxytocin combination are probably the top uterotonics for primary postpartum hemorrhage prevention. Large scale studies exploring different routes of administration for available prophylactic uterotonics, and women's views should be conducted.

Abstract
Background: Several centers have reported their experience with single-port robot-assisted partial nephrectomy (SP-RAPN); however, it is uncertain if utilization of this platform represents an improvement in outcomes compared to multiport robot-assisted partial nephrectomy (MP-RAPN). To evaluate this, we performed a meta-analysis to compare the perioperative, oncological, and functional outcomes between SP-RAPN and MP-RAPN. Methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until January 1, 2023. A meta-analysis has been reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 and assessing the methodological quality of systematic reviews (AMSTAR) guidelines. The odds ratio (OR) and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI). Results: Of the 374 retrieved abstracts, 29 underwent full-text review, and 8 studies were included in the final analysis, comprising a total cohort of 1007 cases of RAPN (453 SP-RAPN cases and 554 MP-RAPN cases). Compared to MP-RAPN, the SP-RAPN group had a significantly longer ischemia time (MD = 4.6 minutes, 95% CI 2.8 to 6.3, p < 0.001), less estimated blood loss (MD = -12.4 mL, 95% CI -24.6 to -0.3, p = 0.045), higher blood transfusion rate (OR = 2.97, 95% CI 1.33 to 6.65, p = 0.008), and higher postoperative estimated glomerular filtration rate (eGFR) at 6 months (MD = 4.9 mL/min, 95% CI 0.2 to 9.7, p = 0.04). There was no significant difference in other outcomes between the two approaches, including the intraoperative complication, overall postoperative complication, minor postoperative complication (Clavien-Dindo I - II), major postoperative complication (Clavien-Dindo III-V), conversion to radical nephrectomy, pain score on day #1, pain score on discharge, morphine milligram equivalent usage, hospital stay, positive surgical margins, and postoperative eGFR. Conclusions: SP-RAPN represents an emerging technique using a novel platform. Initial studies have demonstrated that SP-RAPN is a safe and feasible approach to performing partial nephrectomy, although with inferior outcomes for ischemia time and blood transfusion rates. Further studies will be necessary to define the best usage of SP-RAPN within the surgeon's armamentarium.

Abstract
BACKGROUND Scoliosis surgeries in adults often have a high risk of massive blood loss and significant transfusion of blood products during and after surgery. It is not known whether early cryoprecipitate therapy is useful in reducing blood loss and transfusion requirements. The objective of this randomised, prospective placebo control study was to evaluate whether prophylactic administration of cryoprecipitate would reduce blood loss and transfusion requirements during scoliosis surgery. METHODS Eighty adult patients scheduled to undergo elective scoliosis correction were randomly assigned to receive either ten units of cryoprecipitate before incision (cryo group) or an equivalent volume of 0.9% saline (placebo group). Blood loss, transfusion requirements, coagulation parameters and complications were assessed. RESULTS No significant differences were found in the volume of transfused blood products, intraoperative estimated blood loss between the intervention and placebo groups. Postoperative blood loss was significantly lower in the cry group when compared to the other group. During adult surgical correction of scoliosis, prophylactic administration of cryoprecipitate did not diminish the amount of transfused blood products or decrease intraoperative blood loss. CONCLUSION It could be concluded that the prophylactic administration of cryoprecipitate shows no differences in intraoperative blood loss and transfusion requirements during scoliosis surgery.

Abstract
Objectives Operation notes are important for care in surgical patients. The objectives of this study were to analyze the emergency general surgery (EGS) operation note documentation in accordance with the Royal College of Surgeons of England (RCSEng) guidelines and to assess the impact of creating awareness of the guidelines and effect of a new proforma. Material and Methods A retrospective review of 50 EGS operation notes was conducted between December 2019 and March 2020 and compared to RCSEng guidelines. Education was delivered on the importance of documentation in accordance with RCSEng guidelines. A new electronic proforma was introduced. A further 50 EGS operation notes were analysed between August 2020 and December 2020. Results One hundred operation notes were reviewed, and each given a score out of 19. Our interventions showed significant improvement to the average score (15.64 vs 17.96; p <0.001). Within the second cycle, there was a statistically significance difference when comparing electronic to handwritten notes (18.55 vs 17.50; p= 0.001). Conclusion Implementation of the new proforma showed improvement in operation note documentation when compared to the RCSEng standard. Therefore, this study emphasizes the need for surgeons to familiarize themselves with the current guidelines.

Yu C, Lin YM, Xian GZ. Hemoglobin loss method calculates blood loss during pancreaticoduodenectomy and predicts bleeding-related risk factors. World J Gastrointest Surg 2024; 16:419-428. [PMID: 38463360 PMCID: PMC10921204 DOI: 10.4240/wjgs.v16.i2.419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 12/26/2023] [Accepted: 01/19/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND The common clinical method to evaluate blood loss during pancreaticoduodenectomy (PD) is visual inspection, but most scholars believe that this method is extremely subjective and inaccurate. Currently, there is no accurate, objective method to evaluate the amount of blood loss in PD patients. AIM The hemoglobin (Hb) loss method was used to analyze the amount of blood loss during PD, which was compared with the blood loss estimated by traditional visual methods. The risk factors for bleeding were also predicted at the same time. METHODS We retrospectively analyzed the clinical data of 341 patients who underwent PD in Shandong Provincial Hospital from March 2017 to February 2019. According to different surgical methods, they were divided into an open PD (OPD) group and a laparoscopic PD (LPD) group. The differences and correlations between the intraoperative estimation of blood loss (IEBL) obtained by visual inspection and the intraoperative calculation of blood loss (ICBL) obtained using the Hb loss method were analyzed. ICBL, IEBL and perioperative calculation of blood loss (PCBL) were compared between the two groups, and single-factor regression analysis was performed. RESULTS There was no statistically significant difference in the preoperative general patient information between the two groups (P > 0.05). PD had an ICBL of 743.2 (393.0, 1173.1) mL and an IEBL of 100.0 (50.0, 300.0) mL (P < 0.001). There was also a certain correlation between the two (r = 0.312, P < 0.001). Single-factor analysis of ICBL showed that a history of diabetes [95% confidence interval (CI): 53.82-549.62; P = 0.017] was an independent risk factor for ICBL. In addition, the single-factor analysis of PCBL showed that body mass index (BMI) (95%CI: 0.62-76.75; P = 0.046) and preoperative total bilirubin > 200 μmol/L (95%CI: 7.09-644.26; P = 0.045) were independent risk factors for PCBL. The ICBLs of the LPD group and OPD group were 767.7 (435.4, 1249.0) mL and 663.8 (347.7, 1138.2) mL, respectively (P > 0.05). The IEBL of the LPD group 200.0 (50.0, 200.0) mL was slightly greater than that of the OPD group 100.0 (50.0, 300.0) mL (P > 0.05). PCBL was greater in the LPD group than the OPD group [1061.6 (612.3, 1632.3) mL vs 806.1 (375.9, 1347.6) mL] (P < 0.05). CONCLUSION The ICBL in patients who underwent PD was greater than the IEBL, but there is a certain correlation between the two. The Hb loss method can be used to evaluate intraoperative blood loss. A history of diabetes, preoperative bilirubin > 200 μmol/L and high BMI increase the patient's risk of bleeding.

Abstract
The intraoperative estimated blood loss (EBL), an essential parameter for perioperative management, has been evaluated by manually weighing blood in gauze and suction bottles, a process both time-consuming and labor-intensive. As the novel EBL prediction platform, we developed an automated deep learning EBL prediction model, utilizing the patch-wise crumpled state (P-W CS) of gauze images with texture analysis. The proposed algorithm was developed using animal data obtained from a porcine experiment and validated on human intraoperative data prospectively collected from 102 laparoscopic gastric cancer surgeries. The EBL prediction model involves gauze area detection and subsequent EBL regression based on the detected areas, with each stage optimized through comparative model performance evaluations. The selected gauze detection model demonstrated a sensitivity of 96.5% and a specificity of 98.0%. Based on this detection model, the performance of EBL regression stage models was compared. Comparative evaluations revealed that our P-W CS-based model outperforms others, including one reliant on convolutional neural networks and another analyzing the gauze's overall crumpled state. The P-W CS-based model achieved a mean absolute error (MAE) of 0.25 g and a mean absolute percentage error (MAPE) of 7.26% in EBL regression. Additionally, per-patient assessment yielded an MAE of 0.58 g, indicating errors < 1 g/patient. In conclusion, our algorithm provides an objective standard and streamlined approach for EBL estimation during surgery without the need for perioperative approximation and additional tasks by humans. The robust performance of the model across varied surgical conditions emphasizes its clinical potential for real-world application.

Abstract
BACKGROUND Blood loss during major abdominal surgery is an essential parameter in the evaluation of strategies aimed at reducing perioperative bleeding. However, blood loss quantification remains unreliable and inaccurate. The aim of this study was to compare several methods of blood loss quantification-visual estimation by surgeon and anesthesiologist, the gravimetric method, the calculation method with spectrophotometric measurement. The spectrophotometric measurement is considered as the most accurate method. METHODS The study was designed as a prospective observational cohort single-center study. We analyzed 61 patients who underwent elective liver or pancreatic resection. The anesthesiologists' and surgeons' estimate of blood loss was based on a visual assessment. The gravimetric method was based on weighing the suction canister and surgical drapes before and after use. The basis of calculation method was anthropometric and hematological parameters, we used López-Picado's formula. The spectrophotometric method was based on the spectrophotometric determination of hemoglobin mass in the lost blood. We compared the methods using paired t-test, non-parametric Wilcoxon test and Bland-Altman analysis. RESULTS Visual estimation by surgeons and anesthesiologists, gravimetric measurement, and calculation method were significantly different from spectrophotometric measurement at the significance level α = 0.05. All methods overestimated blood loss which was measured by spectrophotometric method. The estimate by surgeons was the closest to the spectrophotometric measurement, difference 68.7 ml (95% confidence interval [CI]: -129.3--8.2). CONCLUSIONS We conclude that the estimate of blood loss by surgeons and anesthesiologists, as well as gravimetric method and calculation method are all significantly inaccurate in real surgical setting. We did not confirm the commonly accepted assumption that surgeons underestimate the blood loss. TRIAL REGISTRATION The study was registered under the title " Blood Loss Quantification During Major Abdominal Surgery" at ClinicalTrials.gov with the registration number NCT05316649. Date of the first registration was 20/3/2022.

Abstract
OBJECTIVE To assess the incidence of peripartum hysterectomy (PH) in Slovakia. Additionally, we wanted to describe reasons for the procedure, associated clinical circumstances, and complications. METHODS This was a descriptive, population-based study among women who underwent PH in Slovakia between January 2012 and December 2020. Peripartum hysterectomy was defined as surgical removal of the uterus from the peripartum period up to 42 days postpartum. Data were obtained retrospectively from the standardized questionnaires that are completed in Slovakia for any case of PH. The background population consisted of all other women who delivered during the study period. RESULTS Of the 436 136 births, there were 397 cases of PH, giving an incidence of 0.91 per 1000 births. It was higher with advanced maternal age, multiparity, multiple pregnancies, and cesarean deliveries. The main reasons for the procedure were placental pathologies and uterine atony in 52.9% and 33.0%, respectively. A total of 150 (37.8%) women required admission to an intensive care unit. The mortality rate was 1.5%. CONCLUSION The incidence of PH is relatively high in Slovakia when compared with other European countries, highlighting the need to improve prenatal diagnosis of morbidly adherent placenta and the management of peripartum hemorrhage.

Abstract
OBJECTIVE to compare the effectiveness of different diagnostic methods to estimate postpartum blood volume loss. METHODS a systematic review of effectiveness according to PRISMA and JBI Protocol. Searches in PubMed/MEDLINE, LILACS, Scopus, Embase, Web of Science and CINAHL, with descriptor "Postpartum Hemorrhage" associated with keyword "Quantification of Blood Loss". Tabulated extracted data, presented in metasynthesis and meta-analysis was applied to quantitative data. To assess risk of bias, JBI Appraisal Tools were applied. RESULTS fourteen studies were included, published between 2006 and 2021. Quantification of loss by any method was superior to visual estimation and is highly recommended, however the studies' high heterogeneity did not allow estimating this association. CONCLUSION the studies' high heterogeneity, with a probable margin of error given the uncontrolled factors, indicates the need for further studies, however quantification proved to be effective in relation to visual estimate.

"Parenchyma transection-first" strategy is superior to "tunnel-first" strategy in robotic spleen-preserving distal pancreatectomy with conservation of splenic vessels. Hepatobiliary Pancreat Dis Int 2023; 22:639-644.

Abstract
BACKGROUND Creating a tunnel between the pancreas and splenic vessels followed by pancreatic parenchyma transection ("tunnel-first" strategy) has long been used in spleen-preserving distal pancreatectomy (SPDP) with splenic vessel preservation (Kimura's procedure). However, the operation space is limited in the tunnel, leading to the risks of bleeding and difficulties in suturing. We adopted the pancreatic "parenchyma transection-first" strategy to optimize Kimura's procedure. METHODS The clinical data of consecutive patients who underwent robotic SPDP with Kimura's procedure between January 2017 and September 2022 at our center were retrieved. The cohort was classified into a "parenchyma transection-first" strategy (P-F) group and a "tunnel-first" strategy (T-F) group and analyzed. RESULTS A total of 91 patients were enrolled in this cohort, with 49 in the T-F group and 42 in the P-F group. Compared with the T-F group, the P-F group had significantly shorter operative time (146.1 ± 39.2 min vs. 174.9 ± 46.6 min, P < 0.01) and lower estimated blood loss [40.0 (20.0-55.0) mL vs. 50.0 (20.0-100.0) mL, P = 0.03]. Failure of splenic vessel preservation occurred in 10.2% patients in the T-F group and 2.4% in the P-F group (P = 0.14). The grade 3/4 complications were similar between the two groups (P = 0.57). No differences in postoperative pancreatic fistula, abdominal infection or hemorrhage were observed between the two groups. CONCLUSIONS The pancreatic "parenchyma transection-first" strategy is safe and feasible compared with traditional "tunnel-first strategy" in SPDP with Kimura's procedure.

Abstract
Background Proximal femoral and/or pelvic osteotomies (PFPOs) can be indicated for a multitude of hip pathologies in (often asymptomatic) children, to prevent future hip problems. These procedures can result in significant blood loss. Tranexamic acid (TXA) is an antifibrinolytic agent routinely administered in adult trauma and joint reconstruction surgery to reduce blood loss. TXA is also registered for use in children and reported safe and beneficial for pediatric trauma, cardiac, and spinal surgery. However, for pediatric orthopedics, particularly for PFPOs, the available evidence is limited. Therefore, the current trial will investigate the potential reducing effect of preoperative TXA on intraoperative blood loss in pediatric PFPOs. Methods In this single-center, double-blind, randomized placebo-controlled trial, we aim to include 180 participants aged from 1 to 18 years undergoing PFPOs for any indication at our institution. Participants will be randomized to receive either TXA or placebo (saline) during anesthetic induction. The primary outcome is intraoperative estimated blood loss (mL/kg), which is determined gravimetrically. Secondary outcomes include the percentage of patients with excessive blood loss (>20 mL/kg), procedure time and hospital stay, and postoperative hemoglobin level changes. Discussion This will be the first prospective study investigating the effect of preoperative TXA on intraoperative blood loss in pediatric PFPOs. Its results will help to determine whether it would be advisable to adopt preoperative TXA as a standard medication to minimize blood loss and prevent complications in this vulnerable population.

Abstract
Background Blood loss estimation in a surgery is made by anesthesiologists by means of visual technique, which is not reliable because it can change depending on the judgement of every person, or his/her work experience, which is why it is considered something subjective. Therefore, the results obtained could lead to make mistakes with the exact amount of bleeding, mismanaging unnecessary hemoderived transfusions or administering unnecessary drugs. Objective To compare the blood volume and its visual calculation between Anesthesiology residents and anesthesiologists. Material and methods Prolective cross-sectional study which included 85 Anesthesiology residents and anesthesiologists. Diverse scenarios of bleeding were set, divided into gauze pads, compresses and jars, and each participant was asked to answer the poll. Results There is no significant difference in the estimate of bleeding between the estimation made by residents and anesthesiologists. Conclusions The grade of studies or experience is not significant for the exact estimation of bleeding with visual technique.

Abstract
INTRODUCTION Tranexamic acid (TXA) has been proven to prevent thrombolysis and reduce bleeding and blood transfusion requirements in various surgical settings. However, the optimal dose of TXA that effectively reduce intraoperative bleeding and blood product infusion in patients undergoing neurosurgical resection of meningioma with a diameter ≥ 5 cm remains unclear. METHODS This is a single-center, randomized, double-blinded, paralleled-group controlled trial. Patients scheduled to receive elective tumor resection with meningioma diameter ≥ 5 cm will be randomly assigned the high-dose TXA group, the low-dose group, and the placebo. Patients in the high-dose TXA group will be administered with a loading dose of 20 mg/kg TXA followed by continuous infusion TXA at a rate of 5 mg/kg/h. In the low-dose group, patients will receive the same loading dose of TXA followed by a continuous infusion of normal saline. In the control group, patients will receive an identical volume of normal saline. The primary outcome is the estimated intraoperative blood loss calculated using the following formula: collected blood volume in the suction canister (mL)-the volume of flushing (mL) + the volume from the gauze tampon (mL). Secondary outcomes include calculated intraoperative blood loss, intraoperative coagulation function assessed using thromboelastogram (TEG), intraoperative cell salvage use, blood product infusion, and other safety outcomes. DISCUSSION Preclinical studies suggest that TXA could reduce intraoperative blood loss, yet the optimal dose was controversial. This study is one of the early studies to evaluate the impact of intraoperative different doses infusion of TXA on reducing blood loss in neurological meningioma patients.

Effects of Different Hemoglobin Levels on Near-Infrared Spectroscopy-Derived Cerebral Oxygen Saturation in Elderly Patients Undergoing Noncardiac Surgery. Transfus Med Hemother 2023; 50:270-276. [PMID: 37767283 PMCID: PMC10521215 DOI: 10.1159/000528888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 12/28/2022] [Indexed: 09/29/2023] Open
Abstract
Background Near-infrared spectroscopy (NIRS) is a commonly used technique to evaluate tissue oxygenation and prevent harmful cerebral desaturation in the perioperative setting. The aims of the present study were to assess whether surgery-related anemia can be detected via NIRS of cerebral oxygen saturation and to investigate the effects of different perioperative transfusion strategies on cerebral oxygenation, potentially affecting transfusion decision-making. Study Design and Methods Data from the ongoing multicenter LIBERAL-Trial (liberal transfusion strategy to prevent mortality and anemia-associated ischemic events in elderly noncardiac surgical patients, LIBERAL) were used. In this single-center sub-study, regional cerebral oxygenation saturation (rSO2) was evaluated by NIRS at baseline, pre-, and post-RBC transfusion. The obtained values were correlated with blood gas analysis-measured Hb concentrations. Results rSO2 correlated with Hb decline during surgery (r = 0.35, p < 0.0001). Different RBC transfusion strategies impacted rSO2 such that higher Hb values resulted in higher rSO2. Cerebral desaturation occurred at lower Hb values more often. Discussion Cerebral oxygenation monitoring using NIRS provides noninvasive rapid and continuous information regarding perioperative alterations in Hb concentration without the utilization of patients' blood for blood sampling. Further investigations are required to demonstrate if cerebral rSO2 may be included in future individualized transfusion decision strategies.

Longer Operative Time and the Use of Anticoagulants Are Associated With Increased Blood Loss in Elderly Patients Undergoing Arthroscopic Rotator Cuff Repair. Arthrosc Sports Med Rehabil 2023; 5:100743. [PMID: 37645391 PMCID: PMC10461132 DOI: 10.1016/j.asmr.2023.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 05/03/2023] [Indexed: 08/31/2023] Open
Abstract
Purpose To study the effects of rotator cuff tear size, operation time, and the use of anticoagulant on blood loss in elderly patients undergoing arthroscopic rotator cuff surgery. Methods Patients aged older than 65 years who underwent arthroscopic rotator cuff repair with subacromial decompression at our hospital from January 2015 to December 2021 were identified. We measured hemoglobin levels preoperatively, postoperatively, and 7 days after surgery. First, subjects were divided according to the operation time (group I, <90 minutes; group II, <120 minutes; group III <150 minutes; and group IV, >150 minutes). Second, we classified the subjects by the size of the rotator cuff tear (group A, <3 cm; group B, <5 cm; and group C, >5 cm). Lastly, we categorized the subjects into 2 groups according to the use of anticoagulant medication. Results A total of 566 patients were included. The mean hemoglobin (Hgb) levels were 13.8 ± 1.4 g/dL preoperatively, 13.2 ± 1.4 g/dL postoperatively, and 12.8 ± 1.3 g/dL 7 days after surgery, and the differences among them were statistically significant (P < .001). The Hgb level changes 7 days after surgery showed a significant decrease in the group with a longer operation time, and the Hgb loss increased from group 1 to group 4 (P < .001). They did not show any difference in the Hgb levels among the groups according to the size of a cuff tear preoperatively, postoperatively, and 7 days after surgery. The subjects with anticoagulant use showed more decrease in Hgb levels between immediately after the surgery and 7 days after the surgery (P = .031). Still, both groups did not show a statistical difference in the Hgb level 7 days after surgery (P = .115). Conclusions In this study, blood loss after arthroscopic rotator cuff repair in elderly patients was greater than expected. Bleeding increased in elderly patients who had longer surgical times or were taking anticoagulant medications after surgery. Tear size was not associated with a decrease in Hgb levels. Level of Evidence Level III, retrospective comparative study.

[PMID: 37475005 PMCID: PMC10360288 DOI: 10.1186/s13018-023-04018-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 07/14/2023] [Indexed: 07/22/2023] Open
Abstract
BACKGROUND Transforaminal lumbar interbody fusion (TLIF) is an effective and popular surgical procedure for the management of various spinal pathologies, especially degenerative diseases. Surgeons have been pursuing minimally invasive technology as soon as TLIF was appeared. Currently, TLIF can be performed with transforaminal approaches by open surgery, minimally invasive surgery or percutaneous endoscope. We provide a detailed description of a new modified open TLIF with percutaneous pedicle screws, which we refer to as mini-open TLIF. The objective of this study was to present feasibility of this procedure and the preliminary results. METHODS The study is a prospective study. From January 2021 to March 2022, 96 patients (43 males and 53 females) with neurological symptoms due to degenerative lumbar spine diseases were enrolled. Operation time, blood loss, ambulatory time, hematocrit and complications were recorded during perioperative period. Clinical symptoms were evaluated 1 week, 3 months and 12 months after surgery. Visual analogue scale (VAS) scores for lower back pain and leg pain and Oswestry disability index (ODI) were assessed. Magnetic resonance imaging was performed preoperatively and 12 months postoperatively to emulate cross-sectional area of paraspinal muscles. The lumbar interbody fusion rate was evaluated by CT scanning. RESULTS The mean operation time of single level was 112.6 min, and the mean operation time of multilevel was 140.1 min. Intraoperative blood loss of single level was 64.5 ml and was 116.3 ml of multilevel. The VAS and ODI scores before and after surgery were significantly different (P < 0.0001) and reached minimal clinically important difference. Atrophy rate of paraspinal muscles was 2.5% for symptomatic side and 1.2% for asymptomatic side. The cross-sectional area before and after the operation and atrophy rate had no statistically significant difference (P > 0.05). CONCLUSION Mini-open TLIF is effective and feasible for the treatment of lumbar degenerative diseases especially in multilevel disease, with minor damage to muscle and shorter operation time. TRIAL REGISTRATION This study was performed in line with the principles of the Declaration of Helsinki. Approval was granted by the Ethics Committee of the Second Affiliated Hospital of Soochow University (No. JD-LK2023045-I01).

Predictive factors for respiratory failure and in-hospital mortality after surgery for spinal metastasis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:1729-1740. [PMID: 36943483 DOI: 10.1007/s00586-023-07638-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 11/15/2022] [Accepted: 03/05/2023] [Indexed: 03/23/2023]
Abstract
PURPOSE Spinal metastasis surgeries carry substantial risk of complications. PRF is among complications that significantly increase mortality rate and length of hospital stay. The risk factor of PRF after spinal metastasis surgery has not been investigated. This study aims to identify the predictors of postoperative respiratory failure (PRF) and in-hospital death after spinal metastasis surgery. METHODS We retrospectively reviewed consecutive patients with spinal metastasis surgically treated between 2008 and 2018. PRF was defined as mechanical ventilator dependence > 48 h postoperatively (MVD) or unplanned postoperative intubation (UPI). Collected data include demographics, laboratory data, radiographic and operative data, and postoperative complications. Stepwise logistic regression analysis was used to determine predictors independently associated with PRFs and in-hospital death. RESULTS This study included 236 patients (average age 57 ± 14 years, 126 males). MVD and UPI occurred in 13 (5.5%) patients and 13 (5.5%) patients, respectively. During admission, 14 (5.9%) patients had died postoperatively. Multivariate logistic regression analysis revealed significant predictors of MVD included intraoperative blood loss > 2000 mL (odds ratio [OR] 12.28, 95% confidence interval [CI] 2.88-52.36), surgery involving cervical spine (OR 9.58, 95% CI 1.94-47.25), and ASA classification ≥ 4 (OR 6.59, 95% CI 1.85-23.42). The predictive factors of UPI included postoperative sepsis (OR 20.48, 95% CI 3.47-120.86), central nervous system (CNS) metastasis (OR 10.21, 95% CI 1.42-73.18), lung metastasis (OR 7.18, 95% CI 1.09-47.4), and postoperative pulmonary complications (OR 6.85, 95% CI 1.44-32.52). The predictive factors of in-hospital death included postoperative sepsis (OR 13.15, 95% CI 2.92-59.26), CNS metastasis (OR 10.55, 95% CI 1.54-72.05), and postoperative pulmonary complications (OR 9.87, 95% CI 2.35-41.45). CONCLUSION PRFs and in-hospital death are not uncommon after spinal metastasis surgery. Predictive factors for PRFs included preoperative comorbidities, intraoperative massive blood loss, and postoperative complications. Identification of risk factors may help guide therapeutic decision-making and patient counseling.

Abstract
PURPOSE Preoperative malnutrition is associated with postoperative complications, prolonged intensive care unit stay, and mortality, leading to functional disability after non-cardiac surgery. However, its effects on cardiac and thoracic aortic surgery outcomes remain unknown. We examined the effects of preoperative malnutrition on disability-free survival after surgery and assessed the perioperative 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS2.0) score based on the preoperative nutritional status. METHODS We included individuals aged ≥ 55 years who underwent elective cardiac and/or thoracic aortic surgery between April 1, 2016 and December 28, 2018 in a tertiary center. The nutritional status was assessed preoperatively using the Mini Nutritional Assessment Short Form, with scores < 12 points indicating a poor nutritional status. The JapanSCORE2 was calculated for surgical risk prediction. Our primary outcome was disability-free survival 1 year after surgery (WHODAS2.0 score: < 16%). The odds ratio of poor nutritional status for disability-free survival was calculated using multiple logistic regression analysis after adjusting for age, JapanSCORE2, and duration of surgery. RESULTS One hundred patients were followed up for 1 year. Preoperatively, 41 of them had a poor nutritional status. The disability-free survival rates 1 year postoperatively were 46.3% (19/41) and 64.4% (38/59) in patients with and without poor preoperative nutritional status, respectively. The adjusted odds ratio of poor nutritional status for disability-free survival at 1 year after surgery was 0.42 (95% confidence interval, 0.17-0.99). CONCLUSION Patients with a poor preoperative nutritional status had less likely to show disability-free survival 1 year after cardiac and thoracic aortic surgery.

Abstract
Background: Tranexamic acid (TXA) has been used in the management of bleeding. We are conducting a retrospective cohort study to analyse the effect of intravenous TXA infusion on the surgical outcomes of geriatric hip fracture cases which undergoes proximal femoral nail antirotation. Methods: In this study, 364 patients who had undergone proximal femoral nail antirotation between January 2018 and December 2019 in United Christian Hospital have been recruited. Two-hundred thirteen patients were recruited in controlled group and 151 patients were recruited in TXA group. One gram of TXA acid was injected intravenously on induction of anaesthesia and before surgical incision. Outcomes including length of stay, operation time, intraoperative blood loss, haemoglobin and haematocrit drop and post-operative blood transfusion have been measured. Results: There was a reduction in operative time, intraoperative blood loss, post-operative haemoglobin and haematocrit drop and post-operative blood transfusion in TXA group, with a reduction in the intraoperative blood loss (Controlled group: 97.8 ± 67.7 ml, TXA group: 76.0 ± 71.4, Difference −22.3%, p-value: 0.0036) and post-operative haematocrit drop (Controlled group: 0.04 ± 0.03, TXA group: 0.03 ± 0.03, Difference −25%, p-value: 0.05) being statistically significant. The length of stay is not statistically significant between the two groups. TXA is an antifibrinolytic agent which acts by binding to plasminogen which inhibits plasma formation. It has a potential reduction in blood loss in major operations. Conclusion: Intravenous TXA infusion helps to reduce blood loss in a patient undergoing proximal femoral nail antirotation. It is safe to use in the geriatric group of patients. We would recommend the usage of TXA infusion to improve the surgical outcome.

Efficacy of prophylactic pre-operative desmopressin administration during functional endoscopic sinus surgery for chronic rhinosinusitis: A systematic review and meta-analysis of randomised placebo-controlled trials. Clin Otolaryngol 2023; 48:139-150.

Abstract
OBJECTIVES To examine the efficacy of prophylactic desmopressin versus placebo among patients undergoing functional endoscopic sinus surgery (FESS). DESIGN Systematic review and meta-analysis of randomised controlled trials (RCTs). SETTING The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Scopus, and Web of Science databases were screened from inception until 18 March 2022. PARTICIPANTS Patients undergoing FESS. MAIN OUTCOME MEASURES Primary efficacy endpoints comprised intraoperative blood loss, visual clarity, and operation time. Secondary endpoints comprised side effects. The efficacy endpoints were summarised as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). RESULTS Five RCTs comprising 380 patients (desmopressin = 191 patients and placebo = 189 patients) were included. Collectively, the included RCTs had an overall low risk of bias. The pooled results showed that the mean intraoperative blood loss (n = 5 RCTs, MD = -37.97 ml, 95% CI [-56.97, -18.96], p < .001), 5-point Boezaart scores (n = 2 RCTs, MD = -.97, 95% CI [-1.21, -.74], p < .001), and 10-point Boezaart scores (n = 2 RCTs, MD = -3.00, 95% CI [-3.61, -2.40], p < .001) were significantly reduced in favour of the desmopressin group compared with the placebo group. Operation time did not significantly differ between both groups (n = 5 RCTs, MD = -3.73 min, 95% CI [-14.65, 7.18], p = .50). No patient in both groups developed symptomatic hyponatremia (n = 3 RCTs, 194 patients) or thromboembolic events (n = 2 RCTs, 150 patients). CONCLUSIONS Among patients undergoing FESS, prophylactic administration of desmopressin does not correlate with significant clinical benefits. Data on safety is limited. Future research may explore the synergistic antihaemorrhagic efficacy and safety of tranexamic acid (TXA) plus desmopressin versus TXA alone among patients undergoing FESS.

Abstract
PURPOSE To quantify the surgical blood loss during canine enucleation and to investigate the relationship between this and any patient, surgical, and anesthetic factors. METHODS A prospective observational analysis was conducted on 121 client-owned dogs (130 eyes) undergoing enucleation at a referral ophthalmology clinic. Blood loss was estimated by the gravimetric method (weight difference between dry and blood-containing surgical materials) to provide absolute blood loss (ABL) in milliliters, expressed as a percentage of circulating blood volume, to establish relative blood loss (RBL). RESULTS Median ABL was 12 ml (1.6-116 ml), and median RBL was 1.3% (0.1%-6.7%). A higher RBL was associated with the following: use of a bupivacaine splash block versus retrobulbar nerve block (1.9 vs. 1%; p < .001), transpalpebral versus subconjunctival approach (2.2 vs. 1.3%; p = .003), and small versus large breed dogs (1.7% vs. 1.1%; p = .001). Both ABL and RBL differed significantly between surgeons. There was no significant difference in hemorrhage associated with the presence of ocular hypertension, systemic illness, surgical time, administration of meloxicam or choice of pre-medicant (acepromazine vs medetomidine). No dog required supportive intervention in response to surgical hemorrhage. CONCLUSIONS This study has established a surgical blood loss estimate for dogs undergoing enucleation at an ophthalmology referral centre. Subconjunctival enucleation may be preferred for patients at greater risk of haemodynamic complications.

Abstract
Blood loss in major abdominal surgery is an essential parameter in the evaluation of strategies aimed at reducing perioperative bleeding. It is also an important parameter of quality of the surgical procedure, along with postoperative morbidity and mortality, radicality of the surgical resection, etc. However, blood loss quantification remains unreliable and inaccurate. The methods used to measure blood loss can be categorized as visual estimation, gravimetric method, direct measurement, spectrophotometry, calculation methods, colorimetric analysis, and miscellaneous. The aim of this work is to review up-to-date knowledge about the various methods of blood loss quantification and then to introduce study, which should compare more methods of blood loss quantification in a real surgical setting.

Abstract
Systems to optimize the management of postpartum hemorrhage must ensure timely diagnosis, rapid hemodynamic and hemostatic resuscitation, and prompt interventions to control the source of bleeding. None of these objectives can be effectively completed by a single clinician, and the management of postpartum hemorrhage requires a carefully coordinated interprofessional team. This article reviews systems designed to standardize hemorrhage diagnosis and response.

Abstract
INTRODUCTION In elderly patients, an established treatment for femoral neck fractures is hip hemiarthroplasty (HHA) using the anterolateral approach (ALA). Early postoperative mobilization is crucial to reduce perioperative complications. The direct anterior approach (DAA) has been reported to facilitate early recovery of ambulation and is increasingly popular in elective hip surgery but rarely used in femoral neck fractures. The aim was to compare the outcome of the DAA and the ALA in patients treated for femoral neck fracture. MATERIALS AND METHODS All HHAs with complete data sets were reviewed from a tertiary public healthcare institution (2013-2020). Propensity score matching was applied to compensate for possible confounders; outcome parameters were perioperative blood loss, postoperative mobility and pain. Secondary outcomes were duration of surgery, length of stay (LOS), complications, reoperation and mortality rates. RESULTS There were 237 patients (mean age 85.8 years) available for analysis. The DAA group mobilized earlier during hospitalization (outside patient room: 50.6 vs 38.6%, p = 0.01; walking on crutches/walker: 48.1 vs 36.1%, p < 0.01), had shorter surgeries (DAA vs ALA: 72.5 vs 89.5 min, p < 0.001) and a trend towards fewer complications (32.9% vs 44.9%, p = 0.076). Blood loss (286 vs 287 ml), LOS (10.4 vs 9.5 days), pain (cessation of opioid medication: 2.9 vs 3.3 days post-op), revision (2.5 vs 3.2%) or mortality (30-days: 7.6 vs 5.7%) did not differ between patient groups. CONCLUSIONS DAA for HHA led to earlier in-hospital mobility, shorter surgeries and a tendency towards fewer complications. No advantage was found regarding perioperative blood loss and pain.

Abstract
Hemorrhage is responsible for at least 40% of deaths after trauma and 27% of maternal deaths worldwide. Patients with hemorrhagic shock require attentive critical care and transfusion of blood products. Access to a safe and affordable blood supply is critical to providing safe surgical care. Traumatic injury, obstetric hemorrhage, and upper gastrointestinal bleed are the main causes of severe bleeding requiring transfusion. This article discusses the presentation and management of these causes across the world and provides a brief overview of the current challenges in maintaining a global blood supply.

Abstract
Postpartum haemorrhage continues to be a leading cause of morbidity and mortality in the obstetric population worldwide, especially in patients at extremes of body weight. Quantification of blood loss has been considered extensively in the literature. However, these volumes must be contextualised to appreciate the consequences of blood loss for individual parturients. Knowledge of a patient's peripartum circulating blood volume is essential to allow accurate interpretation of the significance of haemorrhage and appropriate resuscitation. Greater body weight in obesity can lead to overestimation of blood volume, resulting in inappropriately high thresholds for blood product transfusion and delays in treatment. The most recent Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries across the UK (MBRRACE-UK) surveillance report demonstrated the risk to this population, with more than half of all maternal mortality recorded in parturients who were either overweight or obese. Current linear calculations used to estimate circulating blood volumes based on patients' weights could be contributing to this phenomenon, as blood volume increases at a disproportional rate to body composition. In this review, we summarise the relevant physiology and explore the existing literature on the estimation of circulating blood volume, both during pregnancy and in obesity. Building on key works and principal findings, we present a practical, nonlinear approach to the adjustment of estimated blood volume with increasing body mass. This clinical tool aims to reduce the clinical bias influencing the management of obstetric haemorrhage in a population already at increased risk of morbidity and mortality. Discussion of the limitations of this approach and the call for further research within this field completes this review.

Abstract
BACKGROUND Pancreaticoduodenectomy is associated with considerable morbidity and mortality rates. Early recognition of patients likely to develop severe postoperative complications will allow the timely commencement of a tailored approach. This study aimed to predict postoperative complications using inflammatory and nutritional markers measured early in the postoperative period. METHODS Patients who underwent pancreaticoduodenectomy between June 2019 and November 2020 were included in the study. Postoperative pancreatic fistula, delayed gastric emptying, and postoperative pancreatic hemorrhage were graded according to the International Study Group of Pancreatic Fistula and the International Study Group of Pancreatic Surgery. We also documented other complications such as wound infection, intra-abdominal collection, and nonsurgical complications. Nutritional and inflammatory markers were analyzed on postoperative days 1 and 3. Patients were followed up for 30 days or until discharge, depending on which was longer. RESULTS Of the 58 enrolled patients, 51 were included in the study. The incidence of postoperative pancreatic fistula was 51% (clinically relevant postoperative pancreatic fistula 27.4%), delayed gastric emptying was 80.4% (clinically relevant delayed gastric emptying 43%), postoperative pancreatic hemorrhage was 3.9%, intra-abdominal collection was 23.5%, and wound infection was 29.4%. The median drain fluid interlukin-6 levels on postoperative day 1 and postoperative day 3 were significantly higher in patients developing clinically relevant postoperative pancreatic fistula than in those who did not develop clinically relevant postoperative pancreatic fistula on postoperative day 1 (211 [125, 425] fg/dL vs 99 [15, 170] fg/dL, [P = .045]) and on postoperative day 3 (110 [22, 28] fg/dL vs 10 [1.8, 45] fg/dL [P = .002]). Patients who tested negative for urine trypsinogen-2 on postoperative day 3 had a significantly lower probability of developing clinically relevant postoperative pancreatic fistula than those who tested positive (1 vs 24 [P < .001]). A model comprising both drain fluid interlukin-6 and urine trypsinogen-2 on postoperative day 3 definitively ruled out the occurrence of clinically relevant postoperative pancreatic fistula. CONCLUSION Drain fluid interlukin-6 and urine trypsinogen-2 on postoperative day 3 ruled out the occurrence of clinically relevant postoperative pancreatic fistula.

Prophylactic tranexamic acid to reduce blood loss and related morbidities during hysterectomy: a systematic review and meta-analysis of randomized controlled trials. Obstet Gynecol Sci 2022; 65:406-419.

Abstract
To perform a systematic review and meta-analysis of all randomized controlled trials (RCTs) that evaluated the efficacy and safety of prophylactic tranexamic acid (TXA) versus a control (placebo or no treatment) during hysterectomy for benign conditions. Six databases were screened from inception to January 23, 2022. Eligible studies were assessed for risk of bias. Outcomes were summarized as weighted mean differences and risk ratios with 95% confidence intervals in a random-effects model. Five studies, comprising six arms and 911 patients were included in the study. Two and three studies had an overall unclear and low risk of bias, respectively. Estimated intraoperative blood loss, requirement for postoperative blood transfusion, and requirement for intraoperative topical hemostatic agents were significantly reduced in a prophylactic TXA group when compared with a control group. Moreover, postoperative hemoglobin level was significantly higher in the prophylactic TXA group than in the control group. Conversely, the frequency of self-limiting nausea and vomiting was significantly higher in the prophylactic TXA group than in the control group. There were no significant differences between the groups in terms of surgery duration, hospital stay, and diarrhea rate. All the RCTs reported no incidence of major adverse events in either group, such as mortality, thromboembolic events, visual disturbances, or seizures. There was no publication bias for any outcome, and leave-one-out sensitivity analyses demonstrated stability of the findings. Among patients who underwent hysterectomy for benign conditions, prophylactic TXA appeared largely safe and correlated with substantial reductions in estimated intraoperative blood loss and related morbidities.

Abstract
Introduction Operation notes are important documents for ensuring patient safety, effective communication between clinicians, and for medicolegal purposes. It is essential that they are clear and accurate. We audited the quality of our operation notes against the Royal College of Surgeons (RCS) of England's Good Surgical Practice Guidelines. Methods This was a prospective audit of 99 orthopedic trauma operation notes. In the first cycle, we audited 58 operation notes for orthopedic trauma surgical procedures. We audited 17 parameters per note. We presented our findings, implemented changes including the use of a typed operation note template, and performed a re-audit using 41 operation notes. Results Our documentation for 3/17 parameters was up to standard in both cycles. Post-intervention, there was an improvement in documentation for 12/17 of the parameters with marked improvements in indication for surgery (45% vs 75%), tourniquet time (20% vs 45%), antibiotic prophylaxis (71% vs 89%), closure technique (62% vs 86%) and detailed postoperative instruction (40% vs 92%). Other parameters, particularly estimated blood loss (7% vs 8%) remained unchanged. In the second cycle, we noted that 25% of the typed notes had 100% compliance with the standards, whereas no handwritten note achieved this. However, there was no statistically significant difference in the mean number of correctly documented parameters between the typed and handwritten notes (p < 0.05). Conclusion The use of operation note templates (preferably typed) can improve appropriate documentation in orthopedic trauma operation notes. These templates should be made easily accessible to all surgeons. We will recommend orthopedic trauma units to apply similar non-rigid templates that can be tailored to suit different categories of trauma surgery.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis of randomized controlled trials on the clinical efficacy and safety of prophylactic tranexamic acid (TXA) versus control (normal saline/no treatment) during myomectomy. METHODS Six databases were screened from inception until 21-February-2022. The eligible studies were assessed for risk of bias. The outcomes were summarized as mean difference (MD) and risk ratio (RR) with 95% confidence intervals (CI) in a random-effects model. RESULTS Seven studies, comprising eight arms and 571 patients (TXA = 304 patients, control = 267 patients) were analyzed. The included studies had an overall low risk of bias. The mean intraoperative blood loss (MD = -224.34 ml, 95% CI [-303.06, -145.61], p < 0.001), mean postoperative blood loss, and mean total blood loss were significantly reduced in favor of the prophylactic TXA group. Additionally, the mean postoperative hemoglobin (MD = 0.4 mg/dl, 95% CI [0.11, 0.68], p = 0.006) and mean postoperative hematocrit levels were significantly higher in favor of the prophylactic TXA group. While the mean hospital stay was significantly reduced in favor of the prophylactic TXA group (MD = -0.39 d, 95% [-0.74, -0.04], p = 0.03), there was no significant difference between both groups regarding the mean operation time and rate of blood transfusion. None of the participants in both groups developed any incidence of thromboembolic events. The rate of nausea was significantly higher in disfavor of the prophylactic TXA group (RR = 2.68, 95% CI [1.11, 6.43], p = 0.03). CONCLUSION Among patients undergoing myomectomy, prophylactic TXA was largely safe and linked to substantial reductions in perioperative blood loss and related morbidities.

Abstract
OBJECTIVE Early excision and grafting of burn wounds are key for reducing prevalence of infection and sepsis. However, it is associated with massive blood loss and patients frequently require large numbers of blood transfusions. This study aimed to evaluate the effect of tranexamic acid (TXA) on blood transfusion requirements in acute burn surgery. METHODS Patients admitted to the burn intensive care unit between January 2018 and May 2021 and received TXA before first surgery for wound excision and grafting were matched in a 1:2 ratio to patients that did not receive TXA (confounders age,sex,total body surface area (TBSA) burned). Primary endpoint of the analysis was the total number of transfused units of red blood cells (RBC) intra- and postoperatively up to 48 h. Fresh frozen plasma (FFP) and platelets were evaluated. Endpoints were compared between groups using van Elteren tests adjusting for strata variable age, gender, TBSA. RESULTS Twenty-six TXA patients were matched with 52 control patients resulting in similar distributions of gender (77.9%(TXA)vs. 82.7%(control) males, p=0.542), age (51.7±21.3vs.48.3 ±17.4years,p = 0.459) and %TBSA burned (33.5%(IQR34)vs. 38.5% (IQR 30.5),p = 1.000). TXA group received significantly less RBC units intraoperatively (2.5(IQR 2.0)vs.4.0 units (IQR4.0), p = 0.038) and in total (4.0(IQR3.0)vs.6.0(IQR4.0),p = 0.017). TXA patients also received less blood products in general (RBC, FFP, platelets) in each period and in total. We found no significant difference in length of stay (24.0(IQR26.0)vs.33.0 days (IQR 0.5),p = 0.367) or mortality (15.4%vs.21.2%, p = 0.542). DISCUSSION This study shows that necessity for blood transfusions in acute burn surgery may be reduced significantly by administration of TXA perioperatively. Randomized-controlled trials are needed to prove these findings.

Abstract
BACKGROUND AND OBJECTIVES Major bleeding and receiving blood products in cancer surgery are associated with increased postoperative complications and worse outcomes. Tranexamic acid (TXA) reduces blood loss and improves outcomes in various surgical specialities. We performed a systematic review and meta-analysis to investigate TXA use on blood loss in elective abdominal and pelvic cancer surgery. METHODS A literature search was performed for studies comparing intravenous TXA versus placebo/no TXA in patients undergoing major elective abdominal or pelvic cancer surgery. RESULTS Twelve articles met the inclusion criteria, consisting of 723 patients who received TXA and 659 controls. Patients receiving TXA were less likely to receive a red blood cell (RBC) transfusion (p < 0.001, OR 0.4 95% CI [0.25, 0.63]) and experienced less blood loss (p < 0.001, MD -197.8 ml, 95% CI [-275.69, -119.84]). The TXA group experienced a smaller reduction in haemoglobin (p = 0.001, MD -0.45 mmol/L, 95% CI [-0.73, -0.18]). There was no difference in venous thromboembolism (VTE) rates (p = 0.95, OR 0.98, 95% CI [0.46, 2.08]). CONCLUSIONS TXA use reduced blood loss and RBC transfusion requirements perioperatively, with no significant increased risk of VTE. However, further studies are required to assess its benefit for cancer surgery in some sub-specialities.

Use of Tranexamic Acid for Elective Resection of Intracranial Neoplasms: A Systematic Review. World Neurosurg 2022; 160:e209-e219. [PMID: 34995825 DOI: 10.1016/j.wneu.2021.12.117] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 12/29/2021] [Accepted: 12/30/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND As an established antifibrinolytic agent, tranexamic acid (TXA) has garnered widespread use during surgery to limit intraoperative blood loss. In the field of neurosurgery, TXA is often introduced in cases of traumatic brain injury or elective spine surgeries; however, its role during elective cranial surgeries is not well established. We report a systematic review of the use of TXA in elective surgical resection of intracranial neoplasms. METHODS We performed this systematic review following PRISMA guidelines to identify studies investigating the use of TXA in elective neurosurgical resection of intracranial neoplasms. Variables extracted included patient demographics, surgical indications, type of surgery performed, TXA dose and route of administration, operative duration, blood loss, transfusion rate, postoperative hemoglobin level, and complications. RESULTS After careful screening, 4 articles (consisting of 682 patients) met our inclusion/exclusion criteria. The studies included 2 prospective cohort studies, 1 retrospective cohort study, and 1 case series. A χ2 test of pooled data demonstrated that patients administered TXA had a significantly decreased need for blood transfusions during surgery (odds ratio, 0.6273; 95% confidence interval, 0.4254-0.9251; P = 0.018). Mean total blood loss was 821.9 mL in the TXA group and 1099.0 mL in the control group across the studies. There was no significant difference in postoperative hemoglobin levels, with a mean of 11.4 g/dL in both the TXA and control groups. CONCLUSIONS These results support the use of intraoperative TXA in tumor resection. However, its role in tumor resection has been less well investigated compared with its use in other areas of neurosurgery.

Abstract
Uncontrolled and massive bleeding with derangement of coagulation is a major challenge in the management of both surgical and seriously injured patients. The underlying mechanism of trauma-induced or -associated coagulopathy is tissue injury in the presence of shock and acidosis provoking endothelial damage, activation of inflammation, and coagulation disbalancing. Furthermore, the combination of ongoing blood loss and consumption of blood components that are essential for effective coagulation worsens uncontrolled hemorrhage. Additionally, therapeutic actions, such as resuscitation with replacement fluids or allogeneic blood products, can further aggravate coagulopathy. Of the coagulation factors essential to the clotting process, fibrinogen is the first to be consumed to critical levels during acute bleeding and current evidence suggests that normalizing fibrinogen levels in bleeding patients improves clot formation and clot strength, thereby controlling hemorrhage. Three different therapeutic approaches are discussed controversially. Whole blood transfusion is used especially in the military scenario and is also becoming more and more popular in the civilian world, although it is accompanied by a strong lack of evidence and severe safety issues. Transfusion of allogeneic blood concentrates in fixed ratios without any targets has been investigated extensively with disappointing results. Individualized and target-controlled coagulation management based on point-of-care diagnostics with respect to the huge heterogeneity of massive bleeding situations is an alternative and advanced approach to managing coagulopathy associated with massive bleeding in the trauma as well as the perioperative setting.

Abstract
INTRODUCTION We designed and implemented a Programmed Learning Simulation (PLS) exercise depicting obstetric scenarios of hemorrhage to train anesthesiologists, ancillary staff, and surgeons to accurately estimate blood loss visually. We then measured the efficacy of this exercise in a clinical setting. METHODS We conducted a prospective study to assess the effect of implementing a PLS exercise on quantification of blood loss in an operative setting. The PLS exercise consisted of 13 simulation stations of varying quantities of simulated blood loss paired with standardized objects of known volume. Eighty-eight individuals participated including attending physicians, residents, medical students, and ancillary staff participated in this study. The PLS was part of regularly scheduled continuing medical education activities; thus, the sampling used was non-randomized convenience method. The percent error was calculated for each of the 13 stations. A subgroup analysis was performed to assess the effect of the years of experience, size of hemorrhage, and occupation on accuracy. Univariate analyses for continuous variables were compared using a one-way ANOVA test. For the comparison of the three groups (years of experience and size of hemorrhage), a p-value of <0.02 was considered statistically significant and for 5-way comparison (professional grouping) a p <0.01 was considered significant after application of the Bonferroni correction (α=0.05). (Part A). To determine the effect of PLS in a clinical setting, the percent error of blood loss estimation for cesarean deliveries during the two-month period after the PLS exercise was compared to the two-month period immediately prior to using the student's t-test with p<0.05 as significant (Part B). Statistical analysis was performed using International Business Machine, Statistical Package for the Social Sciences, Version 26.0 (IBM SPSS). RESULTS During Part A, the baseline performance of the participants was evaluated during the PLS activity. The PLS data showed no significant difference in absolute value of mean percent error estimation (standard deviation) across professions: student 63.61% (69.74), ob/gyn 56.91% (47.72), ancillary 62.15% (77.90), general/trauma surgeon 66.70% (65.06), anesthesia 61.51% (63.12). (p = 0.681), or levels of experience 0-5: 62.21% (60.06), 6-10 years: 56.22% (52.66), greater than 10 years: 61.89% (71.89) (p = 0.831). However, mean percent error of estimation was higher when participants estimated smaller samples 77.7% (104.73) compared to either medium 56.8% (49.06) or large 57.9% (46.19) samples (p<0.001). For Part B, 179 cesarean deliveries occurred during the pre-intervention period and 193 occurred during the post-intervention period. Mean error in provider estimation of blood loss significantly improved from 47% (68.51) pre-intervention to 31% (32.70) post-intervention (p=0.009). CONCLUSION We believe our described PLS activity was effective in teaching techniques for visual blood loss estimation. This was reflected by improved competency in a clinical setting, demonstrated by more accurate visually estimated blood loss during the period immediately following simulation activity compared to a prior time frame. Further research is needed to assess the impact of simulation activities on patient outcomes, such as utilization of blood products and patient morbidity.

Abstract
Background and aim Head and neck cancer is frequent, and surgeries pose more significant morbidity and mortality due to multitudinal causes; heavy blood loss and transfusion are among them. Tranexamic acid (TXA) is known to stabilize the micro clots hence controlling excessive blood loss. The present study aimed to compare perioperative blood loss with two different doses of TXA and placebo to find the effectiveness and optimal dose. Methods With ethical approvals and informed consent, the present prospective, randomized, double-blind, controlled study was conducted in a teaching institute from May 31, 2018, to Dec 28, 2019. Patients undergoing elective head and neck cancer (HNC) surgeries were included. Preoperative Hb < 7 gm% or > 16 gm%, known coagulopathy, anticoagulant therapy, contraindications to TXA, intraoperative torrential or blood loss due to arterial injury were excluded. Group T-1 received TXA 10mg/kg, T-II received 15 mg/kg, while the control group (Gr-C) received equal volume normal saline. Data about demography, surgical time, intraoperative and postoperative blood loss, and transfusion were collected and compared. SPSS software was used for analysis; p-value <0.05 was considered significant. Results Ninety patients were screened, 84 completed the study. All three groups were similar in demographics. The median blood loss with 25th -75th percentile in group C, T-I, and T-II groups were 762.5 (513.5-1193), 541.5 (296.5-787), and 536.0 (180.5 - 879) mL, respectively; p: 0.025. There was a significant difference between the control group and T-I (p-value: 0.0153), and control and T-II (p-value: 0.0248), but an insignificant difference between T-I and T-II (p-value: 0.706). 5 (17.85%) in each of T-I and T-II required transfusion, whereas 14 (50%) in the control group required it; p < 0.011). No major clinically significant related to study drugs were noted. Conclusion Compared to placebo (normal saline), preoperative administration of TXA in bolus significantly reduced perioperative blood losses and transfusion requirement in patients undergoing HNC surgery as estimated using the Hb-based method. A bolus dose of doses of 10mg/kg and 15 mg/kg is equally effective.

Abstract
INTRODUCTION This study was carried out to evaluate role of intravenous tranexamic acid (TXA) in reducing blood loss during tangential excision of burns. METHODS This was a single center, prospective double-blinded parallel arm superiority randomized placebo-controlled trial. Patients (15-55 years) with deep dermal thermal burns <30% undergoing tangential excision were randomly assigned (1:1) to TXA and placebo groups. Patients in TXA and placebo groups received injection TXA 15 mg/kg and 10 ml saline respectively, 10 min preoperatively. Primary outcome was volume of blood loss per square centimeter area of burn excised. Secondary outcomes were total volume of blood loss, postoperative hemoglobin, intraoperative fluid requirement, blood transfusion, graft take and length of hospitalization (LOH). RESULTS Thirty patients were included. Both groups were comparable in terms of Body Mass Index (BMI) preoperative hemoglobin, area of burn excised, duration of surgery and the intraoperative temperature. The average blood loss per square centimeter burn area excised was found to be significantly lower in TXA when compared to placebo group (mean difference: 0.28 ± 0.025 ml/cm2; p = 0.000). The total volume of blood loss was lower in TXA group (258.7 ± 124.10 ml vs 388.1 ± 173.9 ml; p = 0.07). None of the patients required transfusion. The requirement of intra-operative fluids was similar between the two groups (crystalloids: p = 0.236; colloids: p = 0.238). Postoperative hemoglobin, length of hospitalization and graft-take were comparable between the two groups. CONCLUSION TXA reduced blood loss per unit burn area of tangential excision in <30%TBSA burn, however, we found no significant effect on postoperative Hb and transfusion.

Abstract
Objective We evaluated the effects of spontaneous or manual delivery of the placenta and repair of uterine incision inside or outside the abdomen on intraoperative blood loss, postoperative infection morbidity, and postoperative hospitalization time. Materials and Methods We conducted a prospective randomized controlled study with 150 patients among 160 patients who were indicated to undergo emergency cesarean procedures in our tertiary hospital. We divided the patient population into four groups. These four groups were formed by comparing the way the placenta was delivered manually and by spontaneous traction with the repair of the uterus inside and outside the abdomen. Blood loss was determined using quantitative and gravimetric methods. A numeric rating scale was used, which is a one-dimensional method used for uterine sensitivity distribution and pain measurement. Results The amount of bleeding was 339 mL in group 1, 237 mL in group 2, 470 mL in group 3, and 490 mL in group 4, which were significantly different (p<0.001). The mean surgical time was 30.8±5.5 minutes in group 1, 30.7±4.4 minutes in group 2, 38.5±6.9 minutes in group 3, and 43.9 minutes in group 4 (p<0.001). When the distribution of uterine tenderness among the groups was examined in the fundus examinations performed on the postpartum 1st day of the patients, we found a significant difference (p<0.001). When all groups were compared, there was a significant difference between group 1 and group 4 in terms of hospital stay (p<0.004). Among the contributing factors were endometritis, maternal body weight (p<0.053), advanced gestational week (p<0.004), prolonged surgical time (p<0.009), and the presence of meconium. Conclusion Manual removal of the placenta resulted in higher blood loss, increased uterine tenderness, and longer hospitalization compared with the spontaneous separation method. The uterine incision repair site did not affect morbidity.

The visually estimated blood volume in scaled canisters based on a simulation study. BMC Anesthesiol 2021; 21:54.

Abstract
BACKGROUND The most common technique used worldwide to quantify blood loss during an operation is the visual assessment by the attending intervention team. In every operating room you will find scaled suction canisters that collect fluids from the surgical field. This scaling is commonly used by clinicians for visual assessment of intraoperative blood loss. While many studies have been conducted to quantify and improve the inaccuracy of the visual estimation method, research has focused on the estimation of blood volume in surgical drapes. The question whether and how scaling of canisters correlates with actual blood loss and how accurately clinicians estimate blood loss in scaled canisters has not been the focus of research to date. METHODS A simulation study with four "bleeding" scenarios was conducted using expired whole blood donations. After diluting the blood donations with full electrolyte solution, the sample blood loss volume (SBL) was transferred into suction canisters. The study participants then had to estimate the blood loss in all four scenarios. The difference to the reference blood loss (RBL) per scenario was analyzed. RESULTS Fifty-three anesthetists participated in the study. The median estimated blood loss was 500 ml (IQR 300/1150) compared to the RBL median of 281.5 ml (IQR 210.0/1022.0). Overestimations up to 1233 ml were detected. Underestimations were also observed in the range of 138 ml. The visual estimate for canisters correlated moderately with RBL (Spearman's rho: 0.818; p < 0.001). Results from univariate nonparametric confirmation statistics regarding visual estimation of canisters show that the deviation of the visual estimate of blood loss is significant (z = - 10.95, p < 0.001, n = 220). Participants' experience level had no significant influence on VEBL (p = 0.402). CONCLUSION The discrepancies between the visual estimate of canisters and the actual blood loss are enormous despite the given scales. Therefore, we do not recommend estimating the blood loss visually in scaled suction canisters. Colorimetric blood loss estimation could be a more accurate option.

Abstract
PURPOSE Intraoperative estimated blood loss (EBL) is often reported in nearly all surgical papers; however, there is no consensus regarding its measurement. The aim of this study was to determine whether EBL (ml) is as reliable and reproducible in predicting complications as a simple binary grading of EBL. METHODS All consecutive patients undergoing colectomies between January 2015 and December 2018 were included. EBL was assessed prospectively by the surgeon and anaesthesiologist in ml and with a binary scale: bleeding "as usual" versus "more than usual" by the surgeon. Differences between pre- and post-operative haemoglobin levels (ΔHb g/dl) were correlated to EBL. Blood loss impact on 30-day postoperative morbidity was analysed. RESULTS A total of 270 patients were included, with a mean age of 65 years (SD 17). Mean EBL documented by surgeons correlated to EBL by anaesthesiologists (79.5 ml, SD 99 vs. 84.5 ml, SD 118, ϱ = 0.926, p < 0.001). Surgeons and anaesthesiologists' EBL correlated also with ΔHb (ϱ = - 0.273, p = 0.01 and ϱ = - 0.344, p = 0.01, respectively). Patient with surgeon EBL ≥ 250 ml or graded as "more than usual" bleeding had significantly more severe complications (8% vs. 20%, p = 0.02 and 8% vs. 27%, p = 0.001, respectively). CONCLUSION Anaesthesiologist and surgeon's EBL correlated with ΔHb. Simple grading of blood loss as "usual" and "more than usual" predicted severe complications and higher mortality rates. This simple binary grading of blood loss in colon surgery could be an alternative to the estimation of blood loss in ml as it is easy to apply but needs to be validated externally.
