Stop the Bleed in the Era of Virtual Learning: A Novel Strategy for Remote Teaching and Evaluation.

INTRODUCTION: Traumatic hemorrhage is a leading cause of preventable mortality worldwide. The Stop the Bleed (STB) course was developed to equip layperson bystanders with basic bleeding control knowledge and skills. However, large in-person courses have been disrupted due to COVID-19. The aim of this study was to determine the feasibility of teaching and evaluating STB skills through remote video-based instruction. METHODS: After undergoing COVID-19 screening, groups of up to eight STB-naive adults were seated in a socially distanced manner and given individual practice kits. A remote STB-certified instructor provided the standard STB lecture and led a 10-min skills practice session via videoconferencing. Participants' skills were evaluated on a 10-point rubric by one in-person evaluator and three remote evaluators. Participants completed a postcourse survey assessing their perceptions of the course. RESULTS: Thirty-five participants completed the course, all scoring ≥8/10 after examination by the in-person evaluator. Remote instructors' average scores (9.8 ± 0.45) did not significantly differ from scores of the in-person evaluator (9.9 ± 0.37) (P = 0.252). Thirty-three participants (94%) completed the postcourse survey. All respondents reported being willing and prepared to intervene in scenarios of life-threatening hemorrhage, and 97% reported confidence in using all STB skills. CONCLUSIONS: STB skills can be effectively taught and evaluated through a live video-based course. All participants scored highly when evaluated both in-person and remotely, and nearly all reported confidence in skills and knowledge following the course. Remote instruction is a valuable strategy to disseminate STB training to students without access to in-person courses, especially during pandemic restrictions.

The response readiness tool: An instrument to measure knowledge, skills, and attitude after taking a stop the Bleed® course.

Stop the Bleed® is an emergency response course that offers a certificate of completion but no ending assessment. The purpose of this educational study was to develop and test the Response Readiness Tool (RRT) that measures learning of participants after taking Stop the Bleed®. The study used a pre-/post-test design to measure knowledge and attitudes, and a post-test only for skills. Participants were recruited from existing Stop the Bleed® courses. Knowledge was measured with a 10-item questionnaire, attitude was measured with five Likert-style questions, and skills were measured by observing simulated tourniquet placement. Ninety-five participants were recruited over two semesters. There was a significant difference in the knowledge and attitude scores indicating participants' improvement in learning and attitude toward responding. Internal consistency reliability of scores showed moderate reliability with Cronbach's Alpha of 0.73 and McDonald's Omega of 0.75. A positive correlation was found between expected proficiency and pre-test indicating the tool had construct validity. RRT provides Stop the Bleed® instructors with an instrument to measure knowledge, skills, and attitude of participants after taking Stop the Bleed®. Statistics show moderate reliability and validity; however, larger samples are needed for full psychometric testing. This publication presents the revised tool after the completion of this study.

Implementing an approach to prevent life-threatening bleeding: Guidance on forming a campus initiative.

A community that is trained to respond to life-threatening bleeding can reduce the risk of death from trauma and violence. Stop The Bleed is a nationally recognized, free, 1-hour bleeding control training designed for laypersons. Implementing a campuswide Stop the Bleed initiative can be daunting, yet vital to creating a safe, prepared campus. Guidance is offered by faculty, staff, and students from a Stop the Bleed initiative at a public university in the southern United States. This guide provides real-life examples and recommendations based on experience. Utilization of population health nursing students is a fundamental component of success.

Do Experienced Nurses Benefit From Training on Bleeding Control in the Community Setting?

INTRODUCTION: Nurses' preparedness to provide hemorrhage control aid outside of the patient care setting has not been thoroughly evaluated. We evaluated nurses' preparedness to provide hemorrhage control in the prehospital setting after a proof-of-concept training event. METHODS: We performed a secondary analysis of evaluations from a voluntary hemorrhage control training offered to a group of experienced nurses. Education was provided by a nurse certified in Stop the Bleed training and using the Basic Bleeding Control 2.0 materials. The training lasted approximately 1 hour and included a didactic portion followed by hands-on practice with task trainer legs. Participants were surveyed after training to assess their preparedness to provide hemorrhage control aid using a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree); comments and feedback were also requested. Mean (SD) was used to analyze Likert scale data. Content analysis was performed to identify common themes in qualitative data. RESULTS: Forty-five experienced nurses participated in the voluntary training. Nursing experience included obstetrics, pediatrics, critical care, acute care, community health, and psychiatric/mental health. Only 39% of participants reported having previously completed a similar course. After training completion, participants reported an increase in their preparedness to provide hemorrhage control aid (mean 3.47 [SD = 1.40] vs mean 4.8 SD [.04], P < .01). Major themes identified included wanting to feel prepared to help others, refreshing skills, and knowing how to respond in an emergency. DISCUSSION: Regardless of background and experience, nurses may benefit from more advanced hemorrhage control education to prepare them to provide aid in prehospital emergency settings.

Hemostatics in patients with inhibited coagulation-A viscoelastic in-vitro analysis.

BACKGROUND: The military has used topical hemostatic agents to successfully treat life-threatening external bleeding for years. In contrast to the military environment, the general population are increasingly prescribed anticoagulants. There are only few comparative evaluations of topical hemostatic agents with anticoagulated human blood. It is important to understand the impact of these agents on those who take anticoagulants. STUDY DESIGN AND METHODS: Citrated blood of patients treated with enoxaparin, heparin, and acetylsalicylic acid, apixaban or phenprocoumon was incubated with different hemostatic agents (QuikClot Gauze, Celox Granules, Celox Gauze, Chito SAM 100, WoundClot Trauma Gauze, QuikClot Gauze Moulage Trainer and Kerlix) and rotational thromboelastometry was performed with non-activated thromboelastometry (NATEM reagent). RESULTS: All tested agents improved the onset of coagulation in all anticoagulants, mostly to a significant degree. Most significant improvements were produced by QuikClot Gauze and QuikClot Gauze Moulage Trainer, followed by the tested chitosans (Celox Granules, Celox Gauze, Chito SAM 100). Of the anticoagulant groups, the most significant improvements were seen in enoxaparin. This was followed in order by apixaban, heparin, and acetylsalicylic acid, and phenprocoumon. DISCUSSION: All the hemostatic agents tested were able to activate the clotting cascade earlier and initiate faster clot formation in anticoagulated blood. A definitive head-to-head comparison is not feasible, because of the limitations of an in-vitro analysis. However, the sometimes-presented hypothesis that kaolin-based hemostatic agents are ineffective in anticoagulated blood is inaccurate according to our data. Hemostasis with hemostatic agents appears most challenging with phenprocoumon.

Emicizumab dose up-titration in case of suboptimal bleeding control in people with haemophilia A.

INTRODUCTION: Emicizumab promotes effective haemostasis in people with haemophilia A (PwHA). It is indicated for routine prophylaxis of bleeding episodes in PwHA with or without factor (F)VIII inhibitors. AIM: To investigate the effect of emicizumab dose up-titration in PwHA with suboptimal bleeding control. METHODS: Data from seven completed or ongoing phase III studies were pooled. Pharmacokinetics, pharmacodynamics and bleeding events were evaluated before and after dose up-titration. Adverse events (AEs) were compared between PwHA with and without dose up-titration. RESULTS: Of 675 PwHA evaluable for the analysis, 24 (3.6%) had their maintenance dose up-titrated to 3 mg/kg once weekly (QW). Two participants had neutralising antibodies (nAbs) associated with decreased emicizumab exposure, and dose increase did not compensate for the effect of nAbs. In the other 22 participants, mean emicizumab steady-state trough concentrations increased from 44.0 to 86.2 µg/mL after up-titration. The median (interquartile range [IQR]) efficacy period prior to up-titration was 24.6 (24.0-32.0) weeks. The model-based annualised bleed rate for 'treated bleeds' and 'all bleeds' decreased by 70.2% and 72.9%, respectively, after a median (IQR) follow-up of 97.1 (48.4-123.3) weeks in the up-titration period. Incidences of injection-site reactions and serious AEs were higher in PwHA with up-titration; however, this was already observed in these participants before the dose up-titration. Overall, the safety profile appeared similar between PwHA with and without up-titration. CONCLUSION: The dose up-titration to 3 mg/kg QW was well tolerated. Bleed control improved in most participants whose bleeding tendency was inadequately controlled during clinical trials.

Surgical management of endolymphatic sac tumor: classification, outcomes and strategy. A single institution's experience.

PURPOSE: To review the resections of endolymphatic sac tumor (ELST) and describe our experience in the surgical management of ELST. METHODS: Retrospective investigation of consecutive patients who underwent resection of ELSTs at our hospital between 1999 and 2019. The symptoms, diagnosis, surgical findings, and outcomes were analyzed to develop a tumor staging system and corresponding surgical strategy. RESULTS: Retrospective review revealed the surgical treatment of 22 ELSTs. Based on intraoperative findings of tumor extent and size, ELSTs were classified into two types. Type-I (n = 6) referred to the small tumors that were locally confined with limited invasion of semicircular canals and dura; type-II (n = 16) referred to the large tumors that presented extensive erosion of at least one anatomic structure apart from the semicircular canals and the dura around endolymphatic sac. In this case series, Type-I ELST is amenable to resection through a transmastoidal approach, and subtotal petrosectomy is appropriate for the resection of type-II ELST. Sensorineural hearing loss (SNHL) is the most commonly preoperative symptom in both two types of cases. Five type-II ELSTs experienced recurrence and underwent reoperation, whereas all type-I ELSTs did not. CONCLUSION: ELST usually results in SNHL (95%) at the time of diagnosis. The surgical strategy and prognosis of ELST resections are different between type-I and type-II: type-I ELST is amenable to transmastoidal approach with the preservation of facial nerve, whereas type-II ELST increase the surgical difficulty and the risk of recurrence, and subtotal petrosectomy is the basic requirement for the resection of type-II ELST.

Team management in complex posterior spinal surgery allows blood loss limitation.

PURPOSE: The objective is to analyse peri-operative blood loss (BL) and hidden blood loss (HBL) rates in spinal deformity complex cases surgery, with a focus on the strategies to prevent major bleeding. METHODS: We retrospectively analysed surgical and anaesthesiologic data of patients who had been operated for adolescent idiopathic scoliosis (AIS) or adult spinal deformities (ASD) with a minimum of five levels fused. A statistical comparison among AIS, ASD without a pedicle subtraction osteotomy (PSO) (ASD-PSO( -)) and ASD with PSO (ASD-PSO( +)) procedures was performed with a view to identifying patient- and/or surgical-related factors affecting peri-operative BL and HBL. RESULTS: One-hundred patients were included with a mean 9.9 ± 2.8 fused vertebrae and a mean 264.2 ± 68.3 minutes operative time (OT) (28.3 ± 9 min per level). The mean perioperative BL was 641.2 ± 313.8 ml (68.9 ± 39.5 ml per level) and the mean HBL was 556.6 ± 381.8 ml (60.6 ± 42.8 ml per level), with the latter accounting for 51.5% of the estimated blood loss (EBL). On multivariate regression analysis, a longer OT (p < 0.05; OR 3.38) and performing a PSO (p < 0.05; OR 3.37) were related to higher peri-operative BL, while older age (p < 0.05; OR 2.48) and higher BMI (p < 0.05; OR 2.15) were associated to a more significant post-operative HBL. CONCLUSION: With the correct use of modern technologies and patient management, BL in major spinal deformity surgery can be dramatically reduced. Nevertheless, it should be kept in mind that 50% of patients estimated losses are hidden and not directly controllable. Knowing the per-level BL allows anticipating global losses and, possibly, the need of allogenic transfusions.

The Windlass Tourniquet: Is It Taking the Wind Out of the "Stop the Bleed" Sails?

BACKGROUND: Civilians are often first-line responders in hemorrhage control; however, windlass tourniquets are not intuitive. Untrained users reading enclosed instructions failed in 38.2% of tourniquet applications. This prospective follow-up study replicated testing following Stop the Bleed (STB) training. MATERIALS AND METHODS: One and six months following STB, first-year medical students were randomly assigned a windlass tourniquet with enclosed instructions. Each was given one minute to read instructions and two minutes to apply the windlass tourniquet on the TraumaFX HEMO trainer. Demographics, time to read instructions and stop bleeding, blood loss, and simulation success were analyzed. RESULTS: 100 students received STB training. 31 and 34 students completed tourniquet testing at one month and six months, respectively. At both intervals, 38% of students were unable to control hemorrhage (P = 0.97). When compared to the pilot study without STB training (median 48 sec, IQR 33-60 sec), the time taken to read the instructions was shorter one month following STB (P <0.001), but there was no difference at 6 months (P = 0.1). Incorrect placement was noted for 19.4% and 23.5% of attempts at 1 and 6 months. Male participants were more successful in effective placement at one month (93.3% versus 31.3%, P = 0.004) and at six months (77.8% versus 43.8%, p = 0.04). CONCLUSIONS: Skills decay for tourniquet application was observed between 1 and 6 months following STB. Instruction review and STB produced the same hemorrhage control rates as reading enclosed instructions without prior training. Training efforts must continue; but an intuitive tourniquet relying less on mechanical advantage is needed.

Stop the Bleed in Rural Sierra Leone: One Year of Interventions and Outcomes by Nursing Trainees.

BACKGROUND: Low- and middle-income countries (LMICs) bear the bulk of the global burden of traumatic injury, yet many lack adequate prehospital trauma care systems. The Stop the Bleed (STB) course, designed to equip bystanders with bleeding control skills, is infrequently offered in LMICs, and its impact in these settings is unknown. To examine the frequency and effectiveness of STB interventions in LMICs, we quantified nursing student trainees' encounters with bleeding victims after STB training in rural Sierra Leone. METHODS: Local providers and volunteers from a US-based surgical nongovernmental organization taught an STB course to nursing students in Kabala, Sierra Leone. One month and 1 year after the course, trainees completed follow-up surveys describing encounters with traumatic hemorrhage victims since the course. RESULTS: Of 121 total STB trainees, 82 completed the 1-month follow-up survey, with 75% reporting at least one encounter with a bleeding victim. This increased to 98% at 12 months (100 responses, average 2 ± 2 encounters). Injuries were most commonly sustained on victims' legs (32%) and most often precipitated by motorcycle crashes (31%). Respondents intervened in 99% of encounters, and 97% of patients receiving intervention survived. Although only 20% of respondents used a tourniquet, this technique produced the highest survival rate (100%). CONCLUSIONS: Nearly all respondents had encounters with victims of traumatic hemorrhage within 1 year of the STB course, and trainees effectively applied bleeding control techniques, leading to 97% survival among victims receiving intervention. These findings indicate the lifesaving impact of STB training in one rural LMIC setting.

Video-Based Stop the Bleed Training: A New Era in Education.

INTRODUCTION: Uncontrolled bleeding is a leading cause of preventable death. The "Stop the Bleed" (StB) program trains laypersons in hemorrhage control. This study evaluated the efficacy of video-based StB training. METHODS: Participants watched two different videos: a didactic video (DdV) and a technical video (TeV) demonstrating proper techniques for StB skills (i.e., direct pressure [DP], wound packing [WP], and tourniquet application [TA]). Then, they completed a standardized skills examination (SE). Participants were surveyed at three different time points (baseline, post-DdV, and post-SE) for comparison. We compared paired categorical and continuous variables with the McNemar-Bowker test and Wilcoxon signed-rank test, respectively. Alpha was set at 0.05. RESULTS: One hundred six participants were enrolled: 52% were female and the median age was 23 y (22, 24). At baseline, 29%, 8%, and 13% reported being somewhat or extremely confident with DP, WP, and TA, respectively. These percentages increased to 92%, 79%, and 76%, respectively, after the DdV (all, P < 0.0001). After the TeV and SE, percentages increased further to 100%, 96%, and 100% (all, P < 0.0001). During the SE, 96%, 99%, and 89% of participants were able to perform DP, WP, and TA without prompting. Among participants, 98% agreed that the video course was effective and 79% agreed that the DdV and TeV were engaging. CONCLUSIONS: We describe a novel paradigm of video-based StB learning combined with an in-person, standardized SE. Confidence scores in performing the three crucial StB tasks increased significantly during and after course completion. Through remote learning, StB could be disseminated more widely.

Tourniquet Application for Bleeding Control in a Rural Trauma System: Outcomes and Implications for Prehospital Providers.

Introduction: Uncontrolled bleeding is a preventable cause of death in rural trauma. Herein, we examined the appropriateness, effectiveness, and safety of tourniquet application for bleeding control in a rural trauma system.Methods: Medical records of adult patients admitted to our academic Level I trauma center between July 2015 and December 2018 were retrospectively reviewed. Demographics (age, gender), injury (Injury severity score, Glascow Coma scale, mechanism of injury), tourniquet (type, tourniquet application site, tourniquet duration, place of application and removal, indication), and outcome data (complications such as amputation, acute kidney injury, rhabdomyolysis, or nerve palsy and mortality) were collected. Tourniquet indications, effectiveness, and complications were evaluated. Data were compared to those in urban settings.Results: Ninety-two patients (94 tourniquets) were identified, of which 58.7% incurred penetrating injuries. Eighty-seven tourniquets (92.5%) were applied in the prehospital setting. Twenty tourniquets (21.3%) were applied to patients without an appropriate indication. Two of these tourniquets were applied in a hospital setting, while 18 occurred in the prehospital setting (p = 0.638). Patients with a non-indicated tourniquet presented with a higher hemoglobin level on admission, received less packed red blood cell units within the first 24 hours of hospitalization, and were less likely to require surgery for hemostasis. None of the non-indicated tourniquets led to a complication. Indicated tourniquets were deemed ineffective in seven cases (9.5%); they were all applied in the prehospital setting. The average tourniquet time was 123 min in rural vs. 48 min in urban settings, p < 0.001. There was no significant difference in mortality, amputation rates and incidence of nerve palsy between the rural and urban settings.Conclusion: Even with long transport times, early tourniquet application for hemorrhage control in rural settings is safe with no significant attributable morbidity and mortality compared to published studies on urban civilian tourniquet use. The observed rates of non-indicated and ineffective tourniquets indicate suboptimal tourniquet usage and application. Opportunity exists for standardized hemorrhage control training on the use of direct pressure and pressure dressings, indications for tourniquet use, and effective tourniquet application.

Applications of Chitosan in Surgical and Post-Surgical Materials.

The continuous advances in surgical procedures require continuous research regarding materials with surgical applications. Biopolymers are widely studied since they usually provide a biocompatible, biodegradable, and non-toxic material. Among them, chitosan is a promising material for the development of formulations and devices with surgical applications due to its intrinsic bacteriostatic, fungistatic, hemostatic, and analgesic properties. A wide range of products has been manufactured with this polymer, including scaffolds, sponges, hydrogels, meshes, membranes, sutures, fibers, and nanoparticles. The growing interest of researchers in the use of chitosan-based materials for tissue regeneration is obvious due to extensive research in the application of chitosan for the regeneration of bone, nervous tissue, cartilage, and soft tissues. Chitosan can serve as a substance for the administration of cell-growth promoters, as well as a support for cellular growth. Another interesting application of chitosan is hemostasis control, with remarkable results in studies comparing the use of chitosan-based dressings with traditional cotton gauzes. In addition, chitosan-based or chitosan-coated surgical materials provide the formulation with antimicrobial activity that has been highly appreciated not only in dressings but also for surgical sutures or meshes.

Predictors of a difficult Pringle maneuver in laparoscopic liver resection and evaluation of alternative procedures to assist bleeding control.

PURPOSE: To evaluate the predictors of a difficult Pringle maneuver (PM) in laparoscopic liver resection (LLR) and to assess alternative procedures to PM. METHODS: Data from patients undergoing LLR between 2013 and 2020 were reviewed retrospectively. Univariate and multivariate analyses were performed and the outcomes of patients who underwent PM or alternative procedures were compared. RESULTS: Among 106 patients who underwent LLR, PM could not be performed in 18 (17.0%) because of abdominal adhesions in 14 (77.8%) and/or collateral flow around the hepatoduodenal ligament in 5 (27.8%). Multivariate analysis revealed that Child-Pugh classification B (p = 0.034) and previous liver resection (p < 0.001) were independently associated with difficulty in performing PM in LLR. We evaluated pre-coagulation of liver tissue using microwave tissue coagulators, saline irrigation monopolar, clamping of the hepatoduodenal ligament using an intestinal clip, and hand-assisted laparoscopic surgery as alternatives procedures to PM. There were no significant differences in blood loss (p = 0.391) or transfusion (p = 0.518) between the PM and alternative procedures. CONCLUSIONS: Child-Pugh classification B and previous liver resection were identified as predictors of a difficult PM in LLR. The alternative procedures were found to be effective.

The Impact of a Mobile Phone Application for Retention of Bleeding Control Skills.

BACKGROUND: The American College of Surgeons Bleeding Control Course (B-Con) empowers bystanders with hemorrhage control skills to manage prehospital emergencies, but demonstrates poor skill retention. The point of care use of a free Stop the Bleed mobile phone application on the retention of hemorrhage control skills from the B-Con Course was explored. METHODS: Convenience sample of college students previously trained in B-Con were randomized into mobile application (MA) or control groups. The use of a mobile application during a simulated emergency scenario with tourniquet and situational awareness skills was assessed. Wound packing skill retention without intervention was also assessed. Survey data allowed for comparison of participant perceptions of skills with actual performances. RESULTS: MA (n = 30) was superior to control (n = 32) in correct tourniquet application (62.5% versus 30.0%; P = 0.01) with longer placement times (163 sec versus 95 sec; P < 0.001) and in calling 911 (31.3% versus 3.3%, P = 0.004). Participants maintain inflated perceptions of their skills, but generally feel underprepared for a future bleeding emergency. CONCLUSIONS: Mobile apps improve tourniquet and situational awareness skills and may serve as potential aids to improve bystander hemorrhage control skills in real-time, but require further prospective investigation into its use.

Laypeople perception and interpretation of simulated life-threatening bleeding: a controlled experimental study.

INTRODUCTION: First aid performed by immediate responders can be the difference between life and death in the case of trauma with massive bleeding. To develop effective training programs to teach bleeding control to laypersons, it is important to be aware of beliefs and misconceptions people hold on bleeding and severity of bleeding situations. METHOD: A controlled study was conducted in which 175 American college students viewed 78 video clips of simulated bleeding injuries. The volume of blood present (between 0 and 1900 ml), rate of blood flow, and victim gender were systematically varied within participants. Participants were asked to rate injury severity, indicate the appropriate first aid action, and estimate the amount of time until death for the victim. RESULTS: Though the Stop the Bleed® campaign recommends training laypeople to treat 165 ml of blood loss as life threatening, participants largely rated this volume of blood loss as minimal, mild, or moderate and estimated that the victim had just under one hour to live. Increased blood loss was associated with increased recommendations to use a tourniquet. However, in the 1900 ml conditions, participants still estimated that victims had around 22 minutes to live and approximately 15% recommended direct pressure as the intervention. Severity ratings and recommendations to use a tourniquet were also higher for the male victim than the female victim. CONCLUSIONS: Injury classification, intervention selection, and time to death-estimations revealed that training interventions should connect classifications of blood loss to appropriate action and focus on perceptions of how much time one has to respond to a bleeding. The study also revealed a gender related bias in terms of injury classification and first aid recommendations. Bleeding control training programs can be designed to address identified biases and misconceptions while building on existing knowledge and commonly used terminology.

Is laparoscopic hepatectomy suitable for giant hepatic hemangioma larger than 10 cm in diameter?

BACKGROUND: Surgical treatment of giant hepatic hemangioma larger than 10 cm in diameter often requires major laparoscopic liver resection (LLR), which is very difficult and has a high risk of bleeding. There is no consensus as to whether giant hepatic hemangioma is an indication or a contraindication for laparoscopic surgery. METHODS: From 2011/09 to 2018/05, 58 patients with giant hepatic hemangioma larger than 10 cm underwent laparoscopic surgery. They were divided into high-difficulty (HD) group and low-difficulty (LD) group according to the operation difficulty score. The perioperative data of the two groups were analyzed and compared. RESULTS: There were 30 patients in the LD group and 28 in the HD group. No differences were showed in sex, age, ASA grade, tumor size, operation time, conversion rate, intraoperative and post-operative blood transfusion rate, and post-operative complications between the two groups. The amount of bleeding in the HD group was significantly higher than that in the LD group (285.7 ± 224.0 vs 189.6 ± 157.6 ml, p = 0.007). The time of hepatic hilar occlusion in the HD group was longer than that in the LD group (25.4 ± 8.8 vs 20.6 ± 7.3 min, p = 0.001), and the rate of hepatic hilar occlusion in the HD group was also higher than that in the LD group (71.4% vs 33.3%, p = 0.004). The incidence of hospitalization days and discharge time in the LD group were shorter than those in the HD group (6.3 ± 1.6 vs 8.2 ± 1.4 days, p = 0.000; 16.4 ± 5.5 vs 21.9 ± 4.6 h, p = 0.019). There was no significant difference in enzymatic parameters between the two groups after operation. CONCLUSIONS: Although there are great difficulties and risks objectively, laparoscopic treatment of giant hepatic hemangioma is safe and feasible.

Integrating Bleeding Control Training Into Surgical Missions in Low- and Middle-Income Countries.

BACKGROUND: Basic bleeding control (BCon) techniques can save lives globally but the knowledge is not widespread in low-income countries where trauma is a common cause of death. Short-term surgical missions (STSMs) are an effective route to share this public health initiative around the world. MATERIALS AND METHODS: Over 2017-2018, the International Surgical Health Initiative organized STSMs to locations in Sierra Leone, Bangladesh, Peru, and Ghana. The hour-long official American College of Surgeons Basic Bleeding Control course was offered to host participants several times over the course of the mission. Data including number and size of classes, type of trainee, instructors trained, and success rate in demonstrating acquisition of core BCon principles and techniques were collected. RESULTS: Over the course of four, week-long STSMs, 748 people were successfully trained in BCon over 27 sessions, with an average of 28 trainees and up to four instructors per class. One-hundred percent of trainees demonstrated acquisition of required skills proficiency. Trainees included health care workers and those in public security roles. CONCLUSIONS: Concurrent with a short-term surgical mission, a substantial number of health care providers and would-be bystanders can be trained in BCon in countries most impacted by trauma. Local instructors can be trained to teach BCon independently to sustain the initiative. STSMs are a feasible modality to teach bleeding control techniques to an international audience that does not have rapid access to effective prehospital care.

Effect of Continued Administration of Low-dose Aspirin for Intraoperative Bleeding Control in Gastric Endoscopic Submucosal Dissection.

BACKGROUND: The use of antithrombotic agents for the prevention of cerebro-cardioembolic events has increased, and recent guidelines have recommended the continued administration of low-dose aspirin (LDA) during endoscopic procedures with a high risk of bleeding. However, the influence of LDA on intraoperative bleeding control status during Endoscopic submucosal dissection (ESD) remains unclear. METHODS: We examined 293 consecutive patients who underwent ESD for gastric cancers between January 2014 and February 2018. Patients administered with LDA (n = 52) were compared with those without antithrombotic therapy (n = 241; control) by propensity-score matching (PSM) concerning outcomes of ESD. RESULTS: PSM analysis yielded 50 matched pairs. Comparison showed similar values for frequency of intraoperative major bleeding: 1 (0-4) times (median [range]) in the LDA group and 0 (0-5) in the control group respectively (p = 0.710). Others (frequency of preventive coagulation, procedure time, decrease of hemoglobin levels, en bloc resection, complete resection) were the same with a few adverse events including perforation (0%), and thromboembolism (0%). Postoperative bleeding rate was 1.9% in LDA group. Multivariate analysis indicated that location U and circumference on the posterior wall were associated with for multiple major intraoperative bleeding. CONCLUSION: The study suggests that gastric ESD can be safely accomplished without cessation of LDA.
