Rotational ThromboElastometry-guided blood component administration versus standard of care in patients with Cirrhosis and coagulopathy undergoing Invasive ProcEdures (RECIPE): study protocol for a randomised controlled trial. Trials 2023; 24:516. [PMID: 37568228 PMCID: PMC10422802 DOI: 10.1186/s13063-023-07552-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 07/28/2023] [Indexed: 08/13/2023] Open
Abstract
BACKGROUND Patients with cirrhosis often undergo invasive procedures both for management of complications of their advanced liver disease, including treatment for hepatocellular carcinoma, as well as underlying comorbidities. Despite a current understanding that most patients with cirrhosis are in a rebalanced haemostatic state (despite abnormalities in conventional coagulation tests, namely INR and platelet count), patients with cirrhosis are still often given prophylactic blood components based on these conventional parameters, in an effort to reduce procedure-related bleeding. Viscoelastic tests such as Rotational Thromboelastometry (ROTEM) provide a global measurement of haemostasis and have been shown to predict bleeding risk more accurately than conventional coagulation tests, and better guide blood product transfusion in a number of surgical and trauma-related settings. The aim of this study is to assess the utility of a ROTEM-based algorithm to guide prophylactic blood component delivery in patients with cirrhosis undergoing invasive procedures. We hypothesise that ROTEM-based decision-making will lead to a reduction in pre-procedural blood component usage, particularly fresh frozen plasma (FFP), compared with standard of care, whilst maintaining optimal clinical outcomes. METHODS This is a multi-centre randomised controlled trial comparing ROTEM-guided prophylactic blood component administration to standard of care in patients with cirrhosis and coagulopathy undergoing invasive procedures. The primary efficacy outcome of the trial is the proportion of procedures requiring prophylactic transfusion, with the primary safety outcome being procedure-related bleeding complications. Secondary outcomes include the amount of blood products (FFP, platelets, cryoprecipitate) transfused, transfusion-related side effects, procedure-related complications other than bleeding, hospital length of stay and survival. DISCUSSION We anticipate that this project will lead to improved prognostication of patients with cirrhosis, in terms of their peri-procedural bleeding risk. We hope to show that a significant proportion of cirrhotic patients, deemed coagulopathic on the basis of standard coagulation tests such as INR and platelet count, are actually in a haemostatic balance and thus do not require prophylactic blood product, leading to decreased and more efficient blood component use. TRIAL REGISTRATION RECIPE has been prospectively registered with the Australia and New Zealand Clinical Trials Registry on the 30th April 2019 ( ACTRN12619000644167 ).

Abstract
INTRODUCTION Spontaneous bacterial peritonitis (SBP) is a common infection in patients with cirrhosis and ascites and is associated with significant risk of mortality. Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this condition. OBJECTIVE This paper evaluates key evidence-based updates concerning SBP for the emergency clinician. DISCUSSION SBP is commonly due to Gram-negative bacteria, but infections due to Gram-positive bacteria and multidrug resistant bacteria are increasing. The typical presentation of SBP includes abdominal pain, worsening ascites, fever, or altered mental status in a patient with known liver disease; however, some patients may be asymptomatic or present with only mild symptoms. Paracentesis is the diagnostic modality of choice and should be performed in any patient with ascites and concern for SBP or upper gastrointestinal bleeding, or in those being admitted for a complication of cirrhosis. Ultrasound should be used to optimize the procedure. An ascites absolute neutrophil count (ANC) ≥ 250 cells/mm3 is diagnostic of SBP. Ascitic fluid should be placed in blood culture bottles to improve the culture yield. Leukocyte esterase reagent strips can be used for rapid diagnosis if available. While many patients will demonstrate coagulation panel abnormalities, routine transfusion is not recommended. Management traditionally includes a third-generation cephalosporin, but specific patient populations may require more broad-spectrum coverage with a carbapenem or piperacillin-tazobactam. Albumin infusion is associated with reduced risk of renal impairment and mortality. CONCLUSIONS An understanding of literature updates can improve the care of patients with suspected SBP.

Abstract
Cirrhotic patients with severe thrombocytopenia are at increased risk of bleeding during invasive procedures. The need for preprocedural prophylaxis aimed at reducing the risk of bleeding in cirrhotic patients with thrombocytopenia who undergo scheduled procedures is assessed via the platelet count; however, establishing a minimum threshold considered safe is challenging. A platelet count ≥ 50000/μL is a frequent target, but levels vary by provider, procedure, and specific patient. Over the years, this value has changed several times according to the different guidelines proposed in the literature. According to the latest guidelines, many procedures can be performed at any level of platelet count, which should not necessarily be checked before the procedure. In this review, we aim to investigate and describe how the guidelines have evolved in recent years in the evaluation of the minimum platelet count threshold required to perform different invasive procedures, according to their bleeding risk.

Control of bleeding from intercostal artery laceration. Respir Med Case Rep 2022; 40:101783.

Abstract
Laceration of an intercostal artery is a rare but potentially catastrophic complication of pleural procedures such as thoracentesis. Recognition of this problem often occurs late in the bleeding process, only after hemodynamic decompensation has occurred. Aggressive and emergent measures are usually undertaken such as angiographic embolization or thoracotomy. In our review of the literature, manual pressure over the pleural space is not described as an intervention in case reports or case series. We demonstrate the first video proof of the immediate success of direct pressure over an intercostal site as a simple, rapid, and effective method for definitively stopping intercostal arterial hemorrhage after a pleural procedure.

Abstract
With the increasing number of the elderly population, the number of people with respiratory diseases along with other comorbidities is also increasing. With the good number of available evidence, the use of interventional pulmonary procedures is also increasing. However, the studies on the safety and therapeutic benefit of these procedures in the elderly population are limited. Because of the paucity of data, we decided to do a systematic review of the scientific literature that is currently available, to boost confidence to do these procedures by clinicians. This review deals with the procedures that are commonly performed in elderly respiratory patients, their indications, safety and the diagnostic and therapeutic yield, and compares them with the results in the younger population. It also focuses on the safety of anaesthetic techniques used for these procedures in the elderly. The bottom line of this review is that there is no significant difference between the older and younger age groups with regard to the above parameters and that age alone is not a criterion to decide whether the patients may undergo interventional pulmonary procedures.

Abstract
Prolonged prothrombin time and thrombocytopenia are common in patients with cirrhosis. These parameters do not reflect the overall hemostatic rebalance or bleeding risk in the periprocedural setting; however, attempts to correct these parameters remain frequent. We review the literature on periprocedural bleeding risk, bleeding risk factors, and the risk and benefits of hemostatic interventions in patients with cirrhosis. We provide guidance recommendations on evaluating bleeding risk in this patient group and management of hemostatic abnormalities in the periprocedural setting.

Abstract
Thoracentesis is a common bedside procedure, which has a low risk of complications when performed with thoracic ultrasound and by experienced operators. In critically ill or mechanically ventilated patients, or in patients with bleeding risks due to medications or other coagulopathies, the complication rate remains low. Drainage of pleural effusion in the intensive care unit has diagnostic and therapeutic utility, and perceived bleeding risks should be one part of an individualized and comprehensive risk-benefit analysis.

Abstract
Introduction Thoracentesis is one of the most commonly performed procedures in the inpatient setting. Although coagulation profile is usually evaluated prior to thoracentesis, bleeding is a rare complication, occurring in less than 1% of the cases. Several society guidelines recommend holding antiplatelet medications and anticoagulants prior to thoracentesis. Clinical practice guidelines also recommend correcting international normalised ratios of more than two and platelet counts <50 X10∧9/L. Methods This is a retrospective descriptive study that included 292 patients who underwent thoracentesis in the inpatient setting at Ascension St John Hospital in Detroit, Michigan, USA from 2016 to 2018. We identified patients who had uncorrected risk for bleeding and collected data about their demographics, comorbidities, use of antiplatelet or anticoagulants and procedural details including complications. We looked for any postprocedural bleeding events to study their relation to the already established bleeding risk. Results Two hundred and ninety-two thoracenteses were performed, 95.5% (n=279) were performed by interventional radiology. Majority of patients were at risk of bleeding 83% (n=242). No bleeding events occurred. Medications that were not held prior to thoracentesis included: clopidogrel 11% (n=32), novel anticoagulants 8.2% (n=24) and unfractionated heparin 50% (n=146). Use of ultrasound guidance decreased the amount of haemoglobin decline from 1 to 2 g/L (p=0.029). Seventeen patients suffered pneumothorax, eight of which required intervention. Discussion Our study suggests that performing thoracentesis without correction of underlying coagulopathy may be safe. This may prevent consequences of holding essential medications and reduce the amount of blood products administered to patients in need of thoracentesis.

Abstract
BACKGROUND Thoracentesis and tube thoracostomy are common procedures with bleeding risks, but existing guidelines may be overly conservative. We reviewed the evidence on the safety of thoracentesis and tube thoracostomy in patients with uncorrected coagulopathy. RESEARCH QUESTION Is it safe to perform thoracentesis and tube thoracostomy in patients with uncorrected coagulopathy? STUDY DESIGN AND METHODS This systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. PubMed and Embase were searched from inception through December 31, 2019. Included studies involved patients with uncorrected coagulopathy because of disease (eg, thrombocytopenia, liver cirrhosis, kidney failure) or drugs (eg, antiplatelets, anticoagulants). Relevant outcomes were major bleeding and mortality. RESULTS Eighteen studies (5,134 procedures) were included. Using random-effects meta-analysis, the pooled major bleeding and mortality rate was 0 (95% CI, 0%-1%). No publication bias was found. Excluding six studies that were in abstract form, meta-analysis of the remaining 12 full articles showed that the pooled major bleeding and mortality rate also was 0 (95% CI, 0%-2%). Subgroup analysis performed for patients with uncorrected coagulopathy resulting from disease or drugs showed similar results. INTERPRETATION Among patients with uncorrected coagulopathy who underwent thoracentesis or tube thoracostomy, major bleeding and mortality complications were uncommon. Our results suggest that in appropriately selected patients, thoracentesis or tube thoracostomy can be performed safely.

Abstract
Historically, liver disease has been associated with a bleeding tendency. Global hemostatic assays have demonstrated that hemostasis is overall rebalanced, in both acute liver failure and chronic liver disease. It is now recognized that many bleeding events in chronic liver disease are mediated by portal hypertension rather than an underlying hemostatic defect. This is acknowledged in recent guidelines, which recommend against coagulation testing prior to low risk procedures in this patient group, with avoidance also of attempts at correction of prolonged coagulation times. Over time, the incidence of bleeding events has decreased in both chronic liver disease and acute liver failure, with improved supportive care, targeted treatments for underlying cause of liver disease, and the advent of liver transplantation. Concurrently, there has been increased recognition of the risk of thrombosis in chronic liver disease, with a predilection for the splanchnic vasculature. This review describes the incidence of bleeding and thrombosis in chronic liver disease and acute liver failure, including the periprocedural and liver transplantation setting.

Abstract
BACKGROUND Patients undergoing thoracentesis often have comorbid conditions or take medications that potentially put them at higher bleeding risk. Direct oral anticoagulant (DOAC) use has also increased significantly. There are no published guidelines or consensus on when to perform thoracentesis in patients on anticoagulants. Recent studies support the safety of a more liberal approach for thoracentesis among patients with coagulopathy. METHODS We conducted a survey to ascertain the practices of physicians regarding thoracentesis in patients with increased bleeding risk. The survey was administered to the email distribution lists of the American Association of Bronchology and Interventional Pulmonology and of the American Thoracic Society. RESULTS The survey was completed by 256 attending physicians. Most of them were general pulmonologists practicing at academic medical centers. Most of them would perform a thoracentesis in patients receiving acetylsalicylic acid or prophylactic doses of unfractionated heparin or low molecular weight heparin (96%, 89%, and 88%, respectively). Half of the respondents would perform a thoracentesis in patients on antiplatelet medications (clopidogrel and ticagrelor, 51%; ticlopidine, 53%). A minority would perform thoracentesis in patients on direct oral anticoagulants or infused thrombin inhibitors (19% and 12%, respectively). The only subgroup that had a higher proclivity for performing thoracentesis without holding medications were attending physicians practicing for under 10 years. Relative to noninterventional pulmonologists, there were no significant differences in the responses of interventional pulmonologists. CONCLUSION There was variation in the practice patterns of attending physicians in performing thoracentesis in patients with elevated bleeding risk. Further data and guidelines regarding the safety of thoracentesis in these patients are needed.

Abstract
PURPOSE OF REVIEW The present article aims to provide clinicians with an overview of coagulation testing in individuals with liver disease, to discuss available procoagulants and the rationale for their use, and to provide management strategies in a variety of common clinical scenarios. RECENT FINDINGS Clinicians and researchers are gaining an increased understanding of the shortfalls of assessing bleeding risk using traditional tests of coagulation. The use of global tests of clot formation, including viscoelastic testing and thrombin generation analysis, continues to evolve and guide the management of these patients. SUMMARY Abnormal coagulation testing in individuals with cirrhosis leads to a variety of difficult clinical scenarios that can be challenging for practitioners. With advanced liver disease, changes in the traditional tests of hemostasis such as the international normalized ratio reflect decreased synthesis of procoagulant factors but do not capture concomitant decreases in anticoagulant factors. In this setting, transfusion thresholds targeting platelet and fibrinogen goals may provide an effective strategy to optimize clot formation. Global tests of clot formation provide practical information to clinicians and can help guide decision making, although optimal target levels have not been validated.

Periprocedural Major Bleeding Risk of Image-Guided Percutaneous Chest Tube Placement in Patients with an Elevated International Normalized Ratio. J Vasc Interv Radiol 2019; 30:1765-1768. [PMID: 31587947 DOI: 10.1016/j.jvir.2019.07.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Revised: 07/01/2019] [Accepted: 07/02/2019] [Indexed: 12/24/2022] Open
Abstract
PURPOSE To evaluate the incidence of major hemorrhage after image-guided percutaneous chest tube placement in patients with an abnormal international normalized ratio (INR) measured before the procedure. MATERIALS AND METHODS Between January 2013 and September 2017, 49 image-guided percutaneous chest tubes were placed in 45 adult patients who had an elevated INR of greater than 1.6. Data collected included routine serum pre-procedure coagulation studies, indication for chest tube placement, insertion technique, size of chest tube, and presence of complications after drain placement. Major bleeding complications were defined using the Society of Interventional Radiology classification system. RESULTS Mean patient age was 62 years (range, 22-94 years), with median American Society of Anesthesiologists score of 4. Mean INR was 2.1 (range, 1.7-3), with 21 (43%) procedures with an INR between 1.7 and 1.9, 20 (41%) procedures with an INR between 2.0 and 2.4, and 8 (16%) procedures with an INR between 2.5 and 3.0. Computed tomography guidance was used for 27 (55%) procedures; ultrasound guidance was used for 22 (45%) procedures. Median size of chest tube was 10 Fr (range, 8-14 Fr) used in 27 (55%) procedures. No major bleeding complications were observed. There was a small, significant decrease in mean hemoglobin after the procedure (mean = 0.9g/dL; P < .0001), which correlated to increasing chest tube size (P = .0269). CONCLUSIONS No major bleeding complications were observed after image-guided percutaneous chest tube placement in patients with an elevated INR. Major bleeding complications in these patients may be safer than initially considered, and this study encourages the conduct of larger trials for further evaluation.

Abstract
OBJECTIVE To assess the risk of hemorrhagic complications in patients taking novel oral anticoagulants (NOACs) and/or clopidogrel who underwent an ultrasound-guided thoracentesis. PATIENTS AND METHODS A retrospective analysis was performed of ultrasound-guided thoracenteses completed at an academic institution between January 1, 2016, and November 14, 2017. All patients who underwent a thoracentesis while actively receiving treatment with an NOAC and/or clopidogrel were included in the study. Primary endpoints are any significant post-procedure bleeding complication; defined as a hemoglobin decrease of greater than 2 g/dL in 48 hours, hemothorax, chest wall hematoma, and bleeding requiring transfusion, surgery, or chest tube placement. RESULTS A total of 115 thoracenteses were performed in 103 patients actively taking an NOAC (n=43) and/or clopidogrel (n=69). All patients used either the NOAC or clopidogrel within 24 hours before the procedure and continued using it daily thereafter. There were no bleeding complications. CONCLUSION The overall risk of significant hemorrhage in patients taking an NOAC and/or clopidogrel while undergoing ultrasound-guided thoracentesis is very low. Albeit the total number of procedures reviewed may be insufficient to prove definitive safety, it is sufficient to provide a measure of relative risk when assessing benefits of thoracentesis in these patients.

Abstract
DESCRIPTION This expert review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership. The intent is to evaluate the current data on mechanism of altered coagulation in patients with cirrhosis, provide guidance on the use of currently available testing of the coagulation cascade, and help practitioners use anticoagulation and pro-coagulants appropriately in patients with cirrhosis. METHODS This review is framed around the best practice points, which were derived from the most impactful publications in the area of coagulation in cirrhosis and agreed to by all authors. BEST PRACTICE ADVICE 1: Global tests of clot formation, such as rotational thromboelastometry, thromboelastography, sonorheometry, and thrombin generation, may eventually have a role in the evaluation of clotting in patients with cirrhosis, but currently lack validated target levels. BEST PRACTICE ADVICE 2: In general, clinicians should not routinely correct thrombocytopenia and coagulopathy before low-risk therapeutic paracentesis, thoracentesis, and routine upper endoscopy for variceal ligation in patients with hepatic synthetic dysfunction-induced coagulation abnormalities. BEST PRACTICE ADVICE 3: Blood products should be used sparingly because they increase portal pressure and carry a risk of transfusion-associated circulatory overload, transfusion-related acute lung injury, infection transmission, alloimmunization, and/or transfusion reactions. BEST PRACTICE ADVICE 4: The following transfusion thresholds for management of active bleeding or high-risk procedures may optimize clot formation in advanced liver disease: hematocrit ≥25%, platelet count >50,000, and fibrinogen >120 mg/dL. Commonly utilized thresholds for international normalized ratio correction are not supported by evidence. BEST PRACTICE ADVICE 5: Thrombopoietin agonists are a good alternative to platelet transfusion, but require time (about 10 days) to elevate platelet levels. BEST PRACTICE ADVICE 6: The large volume of fresh frozen plasma required to reach an arbitrary international normalized ratio target, limitations of the usual target, minimal effect on thrombin generation, and adverse effects on portal pressure limit the utility of this agent significantly. BEST PRACTICE ADVICE 7: The 4-factor prothrombin complex concentrate contains both pro- and anticoagulant factors that offer an attractive low-volume therapeutic to rebalance a disturbed hemostatic system. However, dosage is, in part, based on international normalized ratio, which is problematic in cirrhosis, and published experience in liver disease is limited. BEST PRACTICE ADVICE 8: Anti-fibrinolytic therapy may be considered in patients with persistent bleeding from mucosal oozing or puncture wound bleeding consistent with impaired clot integrity. Both ε-aminocaproic acid and tranexamic acid inhibit clot dissolution. Neither is believed to generate a hypercoagulable state, although both may exacerbate pre-existing thrombi. BEST PRACTICE ADVICE 9: Desmopressin releases von Willebrand factor as its primary hemostatic mechanism. As this factor is usually elevated in cirrhosis, the agent lacks a sound evidence-based foundation, but may be useful in patients with concomitant renal failure. BEST PRACTICE ADVICE 10: Systemic heparin infusion is recommended for symptomatic deep vein thrombosis and portal and mesenteric vein thrombosis, but there are unresolved issues regarding monitoring with both the anti-Xa assay and the partial thromboplastin time due to cirrhosis-related antithrombin deficiency (heparin cofactor). BEST PRACTICE ADVICE 11: Treatment of incidental portal and mesenteric vein thrombosis depends on estimated impact on transplantation surgical complexity vs risks of bleeding and falls. Therapy with low-molecular-weight heparin, vitamin K antagonists, and direct-acting anticoagulants improve portal vein repermeation vs observation alone. BEST PRACTICE ADVICE 12: Direct-acting anticoagulants, such as the factor Xa and thrombin inhibitors, are relatively safe and effective in stable cirrhotic patients, but are in need of further study in patients with more advanced liver disease.

Abstract
Respiratory diseases are common cause of disability in the elderly and are often concomitant with other non-respiratory medical conditions. Interventional pulmonology includes advanced diagnostic and therapeutic techniques, successfully employed for benign and malignant pulmonary diseases with a good safety profile. A few studies are available on the efficacy and the safety of these procedures (both bronchoscopic and pleural techniques) in the elderly. Paucity of data in these patients may support reluctant clinicians. We carried out a non-systematic review aimed at describing the scientific literature on interventional pulmonology techniques in elderly patients with comorbidities. We summarized indications, performance characteristics, and safety profile of bronchoscopic techniques in the elderly, comparing outcomes between older and younger patients. We explored the role of age on anesthesia and sedation protocols during endoscopic procedures and assessed the influence of comorbidities on bronchoscopic outcomes. This review underlines that older age is not a barrier for implementing interventional pulmonology for diagnostic and therapeutic purposes.

Abstract
The use of transthoracic ultrasound (US) has acquired a wide consensus among respiratory physicians during the last few years. The development of portable devices promotes patient's bedside evaluation providing rapid, real-time and low-cost diagnostic information. The different acoustic impedance between different tissues and organs produces artifacts known as A lines, B lines, sliding sign, lung point, etc. The identification of such artifacts is essential to discriminate normal pleural appearance from the presence of pleural effusion, pneumothorax, thickenings and tumors. Ultrasounds are also a valuable tool during interventional procedures, such as thoracentesis, chest tube insertion and transcutaneous biopsy. Its use is recommended before medical thoracoscopy in order to assess the best site of trocar insertion according to presence, quantity and characteristics of pleural effusion. The aim of this review is to provide practical tips on chest ultrasound in clinical and interventional respiratory practice.

Abstract
BACKGROUND People with thrombocytopenia often require a surgical procedure. A low platelet count is a relative contraindication to surgery due to the risk of bleeding. Platelet transfusions are used in clinical practice to prevent and treat bleeding in people with thrombocytopenia. Current practice in many countries is to correct thrombocytopenia with platelet transfusions prior to surgery. Alternatives to platelet transfusion are also used prior surgery. OBJECTIVES To determine the clinical effectiveness and safety of prophylactic platelet transfusions prior to surgery for people with a low platelet count. SEARCH METHODS We searched the following major data bases: Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2), PubMed (e-publications only), Ovid MEDLINE, Ovid Embase, the Transfusion Evidence Library and ongoing trial databases to 11 December 2017. SELECTION CRITERIA We included all randomised controlled trials (RCTs), as well as non-RCTs and controlled before-and-after studies (CBAs), that met Cochrane EPOC (Effective Practice and Organisation of Care) criteria, that involved the transfusion of platelets prior to surgery (any dose, at any time, single or multiple) in people with low platelet counts. We excluded studies on people with a low platelet count who were actively bleeding. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane for data collection. We were only able to combine data for two outcomes and we presented the rest of the findings in a narrative form. MAIN RESULTS We identified five RCTs, all conducted in adults; there were no eligible non-randomised studies. Three completed trials enrolled 180 adults and two ongoing trials aim to include 627 participants. The completed trials were conducted between 2005 and 2009. The two ongoing trials are scheduled to complete recruitment by October 2019. One trial compared prophylactic platelet transfusions to no transfusion in people with thrombocytopenia in an intensive care unit (ICU). Two small trials, 108 participants, compared prophylactic platelet transfusions to other alternative treatments in people with liver disease. One trial compared desmopressin to fresh frozen plasma or one unit of platelet transfusion or both prior to surgery. The second trial compared platelet transfusion prior to surgery with two types of thrombopoietin mimetics: romiplostim and eltrombopag. None of the included trials were free from methodological bias. No included trials compared different platelet count thresholds for administering a prophylactic platelet transfusion prior to surgery. None of the included trials reported on all the review outcomes and the overall quality per reported outcome was very low.None of the three completed trials reported: all-cause mortality at 90 days post surgery; mortality secondary to bleeding, thromboembolism or infection; number of red cell or platelet transfusions per participant; length of hospital stay; or quality of life.None of the trials included children or people who needed major surgery or emergency surgical procedures.Platelet transfusion versus no platelet transfusion (1 trial, 72 participants)We were very uncertain whether giving a platelet transfusion prior to surgery had any effect on all-cause mortality within 30 days (1 trial, 72 participants; risk ratio (RR) 0.78, 95% confidence interval (CI) 0.41 to 1.45; very-low quality evidence). We were very uncertain whether giving a platelet transfusion prior to surgery had any effect on the risk of major (1 trial, 64 participants; RR 1.60, 95% CI 0.29 to 8.92; very low-quality evidence), or minor bleeding (1 trial, 64 participants; RR 1.29, 95% CI 0.90 to 1.85; very-low quality evidence). No serious adverse events occurred in either study arm (1 trial, 72 participants, very low-quality evidence).Platelet transfusion versus alternative to platelet transfusion (2 trials, 108 participants)We were very uncertain whether giving a platelet transfusion prior to surgery compared to an alternative has any effect on the risk of major (2 trials, 108 participants; no events; very low-quality evidence), or minor bleeding (desmopressin: 1 trial, 36 participants; RR 0.89, 95% CI 0.06 to 13.23; very-low quality evidence: thrombopoietin mimetics: 1 trial, 65 participants; no events; very-low quality evidence). We were very uncertain whether there was a difference in transfusion-related adverse effects between the platelet transfused group and the alternative treatment group (desmopressin: 1 trial, 36 participants; RR 2.70, 95% CI 0.12 to 62.17; very-low quality evidence). AUTHORS' CONCLUSIONS Findings of this review were based on three small trials involving minor surgery in adults with thrombocytopenia. We found insufficient evidence to recommend the administration of preprocedure prophylactic platelet transfusions in this situation with a lack of evidence that transfusion resulted in a reduction in postoperative bleeding or all-cause mortality. The small number of trials meeting the inclusion criteria and the limitation in reported outcomes across the trials precluded meta-analysis for most outcomes. Further adequately powered trials, in people of all ages, of prophylactic platelet transfusions compared with no transfusion, other alternative treatments, and considering different platelet thresholds prior to planned and emergency surgical procedures are required. Future trials should include major surgery and report on bleeding, adverse effects, mortality (as a long-term outcome) after surgery, duration of hospital stay and quality of life measures.

Abstract
The international normalized ratio (INR) represents a clinical tool to assess the effectiveness of vitamin-K antagonist therapy. However, it is often used in the acute setting to assess the degree of coagulopathy in patients with hepatic cirrhosis or acute liver failure. This often influences therapeutic decisions about invasive procedures or the need for potentially harmful and unnecessary transfusions of blood product. This may not represent a best-practice or evidence-based approach to patient care. The author performed a review of the literature related to the utility of INR in cirrhotic patients using several scientific search engines. Despite the commonly accepted dogma that an elevated INR in a cirrhotic patient corresponds with an increased hemorrhagic risk during the performance of invasive procedures, the literature does not support this belief. Furthermore, the need for blood-product transfusion prior to an invasive intervention is not supported by the literature, as this practice increases the risk of complications associated with a patient's hospital course. Many publications ranging from case studies to meta-analyses refute this evidence and provide examples of thrombotic events despite elevated INR values. Alternative methods, such as thromboelastogram, represent alternate means of assessing in vivo risk of hemorrhage in patients with acute or chronic liver disease in real-time in the acute setting.

Abstract
Despite being categorized as a procedure associated with a low risk of iatrogenic hemorrhage, percutaneous pleural drainage in patients taking the ubiquitous antiplatelet agent clopidogrel is still commonly perceived as a risky proposition. There is mounting evidence, however, in support of the safety of percutaneous needle procedures in persons receiving this medication. Establishing that these pleural interventions can be performed safely without clopidogrel interruption would be of great clinical significance, especially in those taking it for recent cardiac stenting and therefore in danger of stent thrombosis should antiplatelet therapy (APT) be withheld. The purpose of the present review is to summarize the available data from published studies and series of thoracentesis and chest tube insertion in patients exposed to clopidogrel. Also incorporated into this review are relevant investigations from the thoracic surgery and interventional radiology experience, which contribute indirect evidence and help shape the context for interpreting the safety data reported in the pleural literature. At the end, an attempt is made to synthesize the current knowledge on this topic into conclusions for guiding practice.

Abstract
Thoracic ultrasound is a powerful diagnostic imaging technique for pleural space disorders. In addition to visualising pleural effusion, thoracic ultrasound also helps clinicians to identify the best puncture site and to guide the drainage insertion procedure. Thoracic ultrasound is essential during these invasive manoeuvres to increase safety and decrease potential life-threatening complications. This paper provides a technical description of pigtail-type drainage insertion using thoracic ultrasound, paying particular attention to indications, contraindications, ultrasound guidance, preparation/equipment, procedure and complications.

Abstract
Synthetic dysfunction observed in cirrhosis results in altered production of procoagulants and anticoagulants that can lead to both bleeding and thrombotic events, respectively. In patients with decompensated cirrhosis, frequent hospital visits often require bedside procedures such as diagnostic paracenteses, thoracenteses and endoscopy. It can be difficult to determine at what coagulation threshold procedures can safely be performed. Currently, the most common therapies given pre-procedurally include fresh frozen plasma (FFP) and vitamin K. The effectiveness of these treatments is estimated by international normalized ratio (INR), an imprecise measure of coagulation in the setting of cirrhosis. Transfusion with FFP may lead to detrimental side effects, including worsening volume overload and increased portal hypertension. We present a case of a 60-year-old patient intubated for acute hypoxic respiratory failure secondary to volume overload who subsequently developed bilateral pneumothoraces, requiring immediate chest tube placement. In this case, the patient had ongoing hepatic decompensation with volume overload and acute worsening of coagulopathy with an INR of 4.2. In this setting, 4-Factor Prothrombin Complex Concentrate (4F-PCC) was chosen to correct coagulation parameters with a low infusion volume. One hour following administration, INR was 1.5. Chest tubes were placed bilaterally and oxygenation improved without bleeding complications. While the data is still lacking, 4F-PCC may be considered for urgent and emergency situations in cirrhotic patients.

Abstract
Spontaneous bacterial peritonitis (SBP) has a high mortality rate; early antimicrobial therapy is essential for improving patient outcomes. Given that cirrhotic patients are often coagulopathic, the perceived risk of bleeding may prevent providers from performing a paracentesis and ruling out this potentially deadly disease. We examine the pathophysiology and risk factors for SBP, and current guidelines for its diagnosis and treatment. We then review the time-sensitive nature of performing a paracentesis, and the current controversies and contraindications for performing this procedure in patients at risk for SBP. Cirrhotic patients with ascites and clinical suspicion for SBP-abdominal pain or tenderness, fever or altered mental status-should have a diagnostic paracentesis. Although most patients with cirrhosis and liver dysfunction will have prolonged prothrombin time, paracentesis is not contraindicated. Limited data support platelet administration prior to paracentesis if <40,000-50,000/μL. Timely antimicrobial therapy includes a third-generation cephalosporin for community-acquired infection; nosocomial infections should be treated empirically with a carbapenem or with piperacillin-tazobactam, or based on local susceptibility testing. Patients with gastrointestinal (GI) hemorrhage should receive ceftriaxone prophylactically for GI hemorrhage. SBP has a high mortality rate. Early diagnosis and antimicrobial therapy are essential for improving patient outcomes. Cirrhotic patients with ascites with clinical suspicion for SBP, abdominal pain or tenderness, altered mental status or fever should have a diagnostic paracentesis performed prior to admission unless platelets <40,000-50,000/μL.

Abstract
PURPOSE To evaluate the safety of withholding preprocedure international normalized ratio (INR) and platelet testing in patients undergoing musculoskeletal (MSK) core needle biopsy (CNB). MATERIAL AND METHODS Initially, a retrospective review of 1,162 consecutive patients undergoing MSK CNB with preprocedural INR and platelet testing was performed. Clinical (age, gender, bleeding disorder, liver disease, anticoagulation use, INR > 2, platelet count <50,000/ul) and biopsy factors (imaging modality, lesion type, biopsy needle gauge, number biopsy samples) were tested for association with bleeding complications. During the second phase, an additional 188 biopsies performed without preprocedural coagulation testing were studied. Categorical variables were compared using Chi-squared or Fisher's exact tests, continuous variables with a student t-test. Multivariate analysis was performed using logistic regression. RESULTS In the first phase, there was a complication rate of 2.6%, 30/1162. Of the 11 clinical and biopsy factors, soft tissue lesions (p = 0.029) and lesions biopsied under ultrasound (p = 0.048) had a higher rate of bleeding than bone lesions or lesions biopsied under CT, respectively. Only three patients had an INR >2, 0.3% (3/1162) and only four patients had platelet count <50,000/ul, 0.3% (4/1162). No patient with a bleeding complication had an abnormal preprocedure bleeding test. In the second phase, there was a bleeding complication rate of 1.1% (2/188). CONCLUSION Bleeding complications from MSK biopsy are low, even when preprocedure coagulation testing is omitted.

Abstract
Abnormal laboratory coagulation test results are frequently documented in critically ill patients, and these patients often also need to undergo invasive procedures. Clinicians have an understandable desire to minimize any perceived heightened risk of bleeding complications in those patients who require invasive procedures. In this setting, prophylactic administration of platelets or plasma is commonplace. This review explores the nature of these sequential statements and the degree to which these statements are supported by evidence. We discuss the complexity of managing the low risk of procedure-related bleeding in a setting where coagulation tests fail to reliably predict this risk. The role of prophylactic transfusion of platelets and plasma and correction of medication-induced coagulopathy is also reviewed. New strategies are required to improve the evidence base, including novel methodological approaches or the use of a clinical scoring system.

Abstract
Peri-procedural anticoagulant management hinges on the balance of hemorrhagic and thrombotic complications. The radiologist is tasked with accurately assessing the hemorrhagic risk for patients undergoing procedures, taking into account procedural bleeding rates, underlying coagulopathy based on lab tests, and use of anticoagulants. The purpose of this article is to provide a contemporary review of commonly used anticoagulants and, incorporating published evidence, review their management related to image-guided procedures.

Abstract
BACKGROUND Physicians often care for patients with pleural effusion, a condition that requires thoracentesis for evaluation and treatment. We aim to identify the most recent advances related to safe and effective performance of thoracentesis. METHODS We performed a narrative review with a systematic search of the literature. Two authors independently reviewed search results and selected studies based on relevance to thoracentesis; disagreements were resolved by consensus. Articles were categorized as those related to the pre-, intra- and postprocedural aspects of thoracentesis. RESULTS Sixty relevant studies were identified and included. Pre-procedural topics included methods for physician training and maintenance of skills, such as simulation with direct observation. Additionally, pre-procedural topics included the finding that moderate coagulopathies (international normalized ratio less than 3 or a platelet count greater than 25,000/μL) and mechanical ventilation did not increase risk of postprocedural complications. Intraprocedurally, ultrasound use was associated with lower risk of pneumothorax, while pleural manometry can identify a nonexpanding lung and may help reduce risk of re-expansion pulmonary edema. Postprocedurally, studies indicate that routine chest X-ray is unwarranted, because bedside ultrasound can identify pneumothorax. CONCLUSIONS While the performance of thoracentesis is not without risk, clinicians can incorporate recent advances into practice to mitigate patient harm and improve effectiveness.

Abstract
Purpose of review The aim of this review is to provide the theoretical and practical
knowledge essential for non-radiologists to develop the skills necessary to apply
thoracic ultrasound as an extension of clinical assessment and
intervention. Recent findings Issues relating to training and competence are discussed and a
library of thoracic ultrasound videos is provided to illustrate artefacts,
pleural, parenchymal and pneumothorax pathology as well as important pitfalls to
consider. Novel and future diagnostic applications of thoracic ultrasound in the
setting of acute cardiorespiratory pathology including consolidation, acute
interstitial syndromes and pulmonary embolism are explored. Summary Thoracic ultrasound requires an understanding of imaging artefact
specific to lung and pleura and a working knowledge of machine knobology for image
optimisation and interpretation. Ultrasound is a valuable tool for the practicing
chest clinician providing diagnostic information for the assessment of pleural and
parenchymal disease and increased safety and cost effectiveness of thoracic
interventions. Electronic supplementary material The online version of this article (doi:10.1007/s13665-017-0164-1) contains supplementary material, which is available to authorized

Abstract
PURPOSE OF REVIEW Although thoracentesis is generally considered safe, procedural complications are associated with increased morbidity, mortality, and healthcare costs. In this article, we review the risk factors and prevention of the most common complications of thoracentesis including pneumothorax, bleeding (chest wall hematoma and hemothorax), and re-expansion pulmonary edema. RECENT FINDINGS Recent data support the importance of operator expertise and the use of ultrasound in reducing the risk of iatrogenic pneumothorax. Although coagulopathy or thrombocytopenia and the use of anticoagulant or antiplatelet medications have traditionally been viewed as contraindications to thoracentesis, new evidence suggests that patients may be able to safely undergo thoracentesis without treating their bleeding risk. Re-expansion pulmonary edema, a rare complication of thoracentesis, is felt to result in part from the generation of excessively negative pleural pressure. When and how to monitor changes in pleural pressure during thoracentesis remains a focus of ongoing study. SUMMARY Major complications of thoracentesis are uncommon. Clinician awareness of risk factors for procedural complications and familiarity with strategies that improve outcomes are essential components for safely performing thoracentesis.

Abstract
Pleural ultrasonography is useful for identifying and characterising pleural effusions, solid pleural lesions (nodules, masses, swellings) and pneumothorax. Pleural ultrasonography is also considered the standard care for guiding interventionist procedures on the pleura at the patient's bedside (thoracentesis, drainage tubes, pleural biopsies and pleuroscopy). Hospitals should promote the acquisition of portable ultrasound equipment to increase the patient's safety.

Abstract
Pleural effusions are common and account for high morbidity and mortality in a range of patients. Thoracentesis can provide significant symptom relief and improvement in physiologic parameters including dyspnea, exercise, and sleep. Recent advances, including the use of ultrasound and dedicated procedural teams, have improved the safety of thoracentesis. This has allowed thoracentesis to be performed on higher-risk individuals including those with elevated bleeding risk and bilateral pleural effusions. This review will summarize recent advances in thoracentesis procedural safety, symptom relief following thoracentesis, and understanding of the physiologic basis for such improvements.

Abstract
Percutaneous abdominal biopsies provide referring physicians with valuable diagnostic and prognostic information that guides patient care. All biopsy procedures follow a similar process that begins with the preprocedure evaluation of the patient and ends with the postprocedure management of the patient. In this review, a step-by-step approach to both routine and challenging abdominal biopsies is covered with an emphasis on the differences in biopsy devices and imaging guidance modalities. Adjunctive techniques that may facilitate accessing a lesion in a difficult location or reduce procedure risk are described. An understanding of these concepts will help maintain the favorable safety profile and high diagnostic yield associated with percutaneous biopsies.

Abstract
OBJECTIVE To determine the incidence of major adverse events related to a large volume of image-guided liver biopsies performed at our institution over a 12-year period and to identify risk factors for major bleeding events. PATIENTS AND METHODS A retrospective analysis of an internally maintained biopsy registry was performed. The analysis revealed that 6613 image-guided liver biopsies were performed in 5987 adult patients between December 7, 2001, and December 31, 2013. Liver biopsies were performed using real-time ultrasound guidance and a spring-loaded biopsy device, with rare exceptions. Adverse events considered major and included in this study were hematoma, infection, pneumothorax, hemothorax, and death. Using data from the biopsy registry, we evaluated statistically significant risk factors (P<.05) for hematoma related to image-guided liver biopsy, including coagulation status, biopsy technique, and medications. RESULTS A total of 49 acute and delayed major adverse events (0.7%) occurred after 6613 liver biopsy events. The incidence of hematoma requiring transfusion and/or angiographic intervention was 0.5% (34 of 6613). The incidence of infection was 0.1% (8 of 6613), and that of hemothorax was 0.06% (4 of 6613). No patient (0%) incurred a pneumothorax after biopsy. Three patients (0.05%) died within 30 days of liver biopsy, 1 being directly related to biopsy. Thirty-eight of 46 major adverse events (83%) presented acutely (within 24 hours). More than 2 biopsy passes, platelets 50,000/μL or less, and female sex were statistically significant risk factors for postbiopsy hemorrhage. CONCLUSION Image-guided liver biopsy performed by subspecialized interventionalists at a tertiary medical center is safe when the platelet count is greater than 50,000/μL. With appreciation of specific risk factors, safety outcomes of this procedure can be optimized in both general and specialized centers.

Abstract
Patients who are critically ill and hospitalized often require invasive procedures as a part of their medical care. Each procedure carries a unique set of risks and associated complications, but common to all of them is the risk of hemorrhage. Central venous catheterization, arterial catheterization, paracentesis, thoracentesis, tube thoracostomy, and lumbar puncture constitute a majority of the procedures performed in patients who are hospitalized. In this article, the authors will discuss the risk factors for bleeding complications from each of these procedures and methods to minimize risk. Physicians often correct coagulopathy prior to procedures to decrease bleeding risk, but there is minimal evidence to support this practice.

Abstract
UNLABELLED Bleeding is a feared complication of invasive procedures in patients with cirrhosis and significant coagulopathy (as defined by routine coagulation tests) and is used to justify preprocedure use of fresh frozen plasma (FFP) and/or platelets (PLT). Thromboelastography (TEG) provides a more comprehensive global coagulation assessment than routine tests (international normalized ratio [INR] and platelet count), and its use may avoid unnecessary blood product transfusion in patients with cirrhosis and significant coagulopathy (defined in this study as INR >1.8 and/or platelet count <50 × 10(9) /L) who will be undergoing an invasive procedure. Sixty patients were randomly allocated to TEG-guided transfusion strategy or standard of care (SOC; 1:1 TEG:SOC). The TEG group would receive FFP if the reaction time (r) was >40 min and/or PLT if maximum amplitude (MA) was <30 mm. All SOC patients received FFP and/or PLT per hospital guidelines. Endpoints were blood product use and bleeding complications. Baseline characteristics of the two groups were similar. Per protocol, all subjects in the SOC group received blood product transfusions versus 5 in the TEG group (100% vs. 16.7%; P < 0.0001). Sixteen SOC (53.3%) received FFP, 10 (33.3%) PLT, and 4 (13.3%) both FFP and PLT. In the TEG group, none received FFP alone (P < 0.0001 vs. SOC), 2 received PLT (6.7%; P = 0.009 vs. SOC), and 3 both FFP and PLT (not significant). Postprocedure bleeding occurred in only 1 patient (SOC group) after large-volume paracentesis. CONCLUSIONS In patients with cirrhosis and significant coagulopathy before invasive procedures, TEG-guided transfusion strategy leads to a significantly lower use of blood products compared to SOC (transfusion guided by INR and platelet count), without an increase in bleeding complications. Remarkably, even in patients with significant coagulopathy, postprocedure bleeding was rare, indicating that TEG thresholds should be reevaluated.

Fresh frozen plasma transfusion fails to influence the hemostatic balance in critically ill patients with a coagulopathy. J Thromb Haemost 2015; 13:989-97.

Abstract
BACKGROUND Coagulopathy has a high prevalence in critically ill patients. An increased International Normalized Ratio (INR) is a common trigger to transfuse fresh frozen plasma (FFP), even in the absence of bleeding. Therefore, FFP is frequently administered to these patients. However, the efficacy of FFP in correcting hemostatic disorders in non-bleeding recipients has been questioned. OBJECTIVES To assess whether INR prolongation parallels changes in the results of other tests investigating hemostasis, and to evaluate the coagulant effects of a fixed dose of FFP in non-bleeding critically ill patients with a coagulopathy. METHODS Markers of coagulation, individual factor levels and levels of natural anticoagulants were measured. Also, thrombin generation and thromboelastometry (ROTEM) assays were performed before and after FFP transfusion (12 mL kg(-1) ) to 38 non-bleeding critically ill patients with an increased INR (1.5-3.0). RESULTS At baseline, levels of factor II, FV, FVII, protein C, protein S and antithrombin were reduced, and thrombin generation was impaired. ROTEM variables were within reference ranges, except for a prolonged INTEM clot formation time. FFP transfusion increased the levels of coagulation factors (FII, 34% [interquartile range (IQR) 26-46] before vs. 44% [IQR 38-52] after; FV, 48% [IQR 28-76] before vs. 58% [IQR 44-90] after; and FVII, 25% [IQR 16-38] before vs. 37% [IQR 28-55] after), and the levels of anticoagulant proteins. Thrombin generation was unaffected by FFP transfusion (endogenous thrombin potential, 72% [IQR 51-88] before vs. 71% [IQR 42-89] after), whereas ROTEM EXTEM clotting time and maximum clot firmness slightly improved in response to FFP. CONCLUSION In non-bleeding critically ill patients with a coagulopathy, FFP transfusion failed to induce a more procoagulant state.

Abstract
Thoracentesis is considered a relatively safe and well-established procedure commonly done at the bedside with minimal risk of complication. Thoracentesis-related hemothorax is uncommon; however, it may be life-threatening. We describe a case of a 19-year-old woman with persistent fever and pleural effusion, in which thoracentesis resulted in tension hemothorax due to intercostal artery laceration. It is important for proceduralists to understand not only the tortuosity of the intercostal artery covering 25% to 50% of the intercostal space, but also the presence of traversing collateral arteries. Herein, we discuss the potential benefit of vascular ultrasonography with color Doppler during thoracentesis, with the goal of avoiding vessel injury and hemorrhage.

Abstract
PURPOSE OF REVIEW Thoracentesis is a commonly performed procedure throughout the world. Convention dictates that patients should have laboratory values such as international normalized ratio (INR) and platelets corrected or medications that affect bleeding withheld prior to performing this procedure. By transfusing blood products or withholding medications, patients are exposed to risks that are different than but equally if not more significant than the risk of hemothorax from thoracentesis. This review highlights recent studies that suggest the parameters of performing thoracentesis should be less stringent than traditionally thought. RECENT FINDINGS Although the safety of thoracentesis has improved with the use of ultrasound and other advancements, the number of patients on new medications that exert an influence on bleeding and those who have physiologic coagulation abnormalities continues to grow. Despite a 1991 study demonstrating the safety of thoracentesis in patients with an abnormal INR or low platelet count, transfusion of blood products to normalize laboratory values is commonplace. A number of studies within the past year address the safety of thoracentesis amidst INR and platelet abnormalities and in patients taking antiplatelet or other medications that affect a patient's bleeding potential. SUMMARY Although large randomized studies do not exist, recent literature suggests that it is time to reevaluate the need to correct INR and platelet counts or to transfuse blood products or withhold medications prior to thoracentesis in patients felt to have a risk of possible bleeding.

Abstract
In transfusion medicine, several blood products can be prepared and used as replacement therapy; however, four of these products are more commonly used in general practice: RBCs, fresh frozen plasma (FFP), platelets and cryoprecipitate. RBC transfusions are mainly administered to improve tissue oxygenation in cases of anaemia or acute blood loss due to trauma or surgery. FFP, platelets and cryoprecipitate are used for the prevention and treatment of bleeding.
