Abstract
There is wide variability in the management of patients on antithrombotic therapy requiring surgery of the hand and wrist. There are no specific guidelines regarding whether to temporarily cease or continue oral anticoagulants and antiplatelet agents. Discontinuation of these medications before surgery can lead to perioperative thromboembolic or ischemic events. On the other hand, continuation can lead to intraoperative or postoperative bleeding complications. This review discusses various anticoagulants and antiplatelet agents with special considerations for their management, analyzes the current literature, summarizes current recommendations, and provides direction for additional research.

Assessing the safety of continued perioperative antithrombotic therapy in endoscopic airway surgery for laryngotracheal stenosis. Am J Otolaryngol 2023; 44:103857. [PMID: 37030129 PMCID: PMC10033492 DOI: 10.1016/j.amjoto.2023.103857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 03/19/2023] [Indexed: 03/25/2023]
Abstract
Purpose Given the increasing utilization of endoscopic surgery, particularly for airway stenosis management in the era of COVID-19 due to prolonged intubation, it is important to examine whether continuing antithrombotic therapy perioperatively influences bleeding complications. We examined the impact of perioperative antithrombotic use on postoperative bleeding complications following endoscopic airway surgery for laryngotracheal stenosis. Materials and methods Retrospective study from January 2016 to December 2021 of cases of patients ≥18 years who underwent endoscopic airway surgery for posterior glottic, subglottic, and tracheal stenosis at a single institution. Cases were excluded if they were an open airway surgery. The primary outcome was the occurrence of postoperative bleeding complications across cases of patients naive to and on baseline antithrombotic therapy, and those with preoperative continuation versus cessation of antithrombotic therapy. Results 258 cases across 96 patients met inclusion criteria. Of these 258 cases, 43.4 % (n = 112) were performed for patients on baseline antithrombotic therapy and 56.6 % (n = 146) for those not on antithrombotic therapy. Likelihood of perioperative continuation of apixaban was 0.052 (odds ratio, 95 % Confidence Interval: 0.002–0.330, p < 0.001). Likelihood of perioperative continuation of aspirin was 9.87 (odds ratio, 95 % Confidence Interval: 2.32–43.0, p < 0.001). Two instances of postoperative bleeding were found: both in patients who were on aspirin without perioperative cessation for COVID-related coagulopathy. Conclusions Our findings suggest that perioperative continuation of aspirin is relatively safe in the setting of endoscopic surgery for airway stenosis management. Prospective investigations to increase understanding of perioperative antithrombotics for COVID-related coagulopathy are warranted.

Proactive Risk Assessment through Failure Mode and Effect Analysis (FMEA) for Perioperative Management Model of Oral Anticoagulant Therapy: A Pilot Project. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16430. [PMID: 36554313 PMCID: PMC9779206 DOI: 10.3390/ijerph192416430] [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: 10/06/2022] [Revised: 12/04/2022] [Accepted: 12/05/2022] [Indexed: 06/17/2023]
Abstract
INTRODUCTION Correct perioperative management of anticoagulant therapy is essential to prevent thromboembolic events and reduce the risk of bleeding. The lack of universally accepted guidelines makes perioperative anticoagulant therapy management difficult. The present study aims to identify the perioperative risks of oral anticoagulant therapy and to reduce adverse events through Failure Mode and Effect Analysis (FMEA). MATERIALS AND METHODS A multidisciplinary working group was set up, and four main phases of the process were identified. Each of these phases was divided into micro-activities to identify the related possible failure modes and their potential consequences. The Risk Priority Number was calculated for each failure mode. RESULTS AND DISCUSSION Seventeen failure modes were identified in the entire perioperative period; those with a higher priority of intervention concern the incorrect timing between therapy suspension and surgery, and the incorrect assessment of the bleeding risk related to the invasive procedure. CONCLUSION The FMEA method can help identify anticoagulant therapy perioperative failures and implement the management and patient safety of surgical procedures.

Abstract
Venous thromboembolism (VTE) is one of the leading causes of post-operative morbidity and mortality. Over previous decades, heparin and warfarin were the predominant therapeutic options for post-operative thromboprophylaxis. However, their use is limited by drawbacks including a narrow therapeutic range, numerous food and drug interactions, and the need for regular monitoring for dose adjustments. Recently, direct oral anticoagulants (DOACs), such as dabigatran etexilate (a direct thrombin inhibitor) and apixaban, rivaroxaban and edoxaban (direct factor Xa inhibitors), have been developed to overcome these issues. DOACs have shown promising results in Phase III clinical trials for post-operative VTE prophylaxis. This review summarises the pharmacological profile of DOACs and highlights the use of DOACs in post-operative VTE prophylaxis based on the available clinical trial data.

Abstract
INTRODUCTION Cardiac patients on antiplatelets or oral anticoagulation undergoing emergent cardiac surgery without appropriate washout periods are at increased risk for developing perioperative bleeding. CytoSorb is a commercially available hemadsorption filter that can simultaneously remove a wide range of substances including ticagrelor, and direct oral anticoagulants (DOACs). Areas covered: Although CytoSorb has been used to remove various protein-bound substances, this review will specifically evaluate and review current evidence for applying CytoSorb in removing ticagrelor and DOACs using 4 in vivo studies, 3 case reports, one retrospective clinical study and 2 cost analysis studies. Based on limited evidence, CytoSorb may be effective in reducing perioperative bleeding as demonstrated by reducing chest tube output, blood product transfusions, and re-thoracotomy rates. CytoSorb can also reduce length of intensive care unit (ICU) and hospital stay. Although, CytoSorb has an initial upfront cost, it was proven to be cost effective due to potential health resource savings on both short- and long-term projections.Expert Commentary: CytoSorb provides a novel strategy to remove ticagrelor and DOACs in patients requiring emergency cardiac surgery. Although promising results, more solid evidence is required to establish its clinical effectiveness in reducing perioperative bleeding, bleeding-related complications, mortality, and finally, its overall safety.

Expedited surgery in geriatric hip fracture patients taking direct oral anticoagulants is not associated with increased short-term complications or mortality rates. OTA Int 2020; 3:e089. [PMID: 33937710 PMCID: PMC8022910 DOI: 10.1097/oi9.0000000000000089] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Accepted: 07/08/2020] [Indexed: 11/26/2022]
Abstract
Objectives: The purpose of this study was to evaluate potential differences in time to surgery, bleeding risk, wound complications, length of stay, transfusion rate, and 30-day mortality between patients anticoagulated with direct oral anticoagulants (DOACs) and those not anticoagulated at the time of evaluation for an acute hip fracture. Design: Retrospective chart review Level III Study. Setting: One university-based hospital in Rochester, NY. Patients/Intervention : Patients 65 years and older undergoing operative treatment of a hip fracture over a 5-year period. Chart review identified patients on DOAC therapy at the time of injury as well as an age and sex-matched control group not on anticoagulation. Main outcome measurements : Demographics, procedure type, admission/postoperative laboratory work, perioperative metrics, transfusion metrics, discharge course, reoperation, readmission, wound complications, and 30-day mortality were obtained for comparison. Results: Thirty-six hip fractures anticoagulated on DOACs were compared to 108 controls. The DOAC group had delays to operative treatment (27.6 h, SD 16.3 h, 95% CL [22.0–33.1]) vs the control group (19.8 h, SD 10.5 h, 95% CL [17.7–21.8], P = .01). No differences were found in estimated blood loss, procedure time, or change in hemoglobin. Transfusion rates were not significantly different between groups (58.3% DOAC vs 47.2% control, P = .25). No difference in reoperation, readmission, wound complication, deep venous thrombosis rates, or 30-day mortality rates were found. Conclusion: Patients presenting on DOAC therapy at the time of hip fracture have a delay to surgery compared with age and sex-matched controls, but no increase in short term complications or mortality rates. Expedited surgery (within 48 h) appeared to be safe and effective treatment for hip fracture patients on DOAC therapies.

Abstract
About 10% of patients taking a chronic, oral anticoagulant therapy require an invasive procedure that can be associated with an increased risk for peri-interventional or perioperative bleeding. Depending on the risk for thromboembolism and the risk for bleeding, the physician has to decide whether the anticoagulant therapy should be interrupted or continued. Patient characteristics such as age, renal function and drug interactions must be considered. The perioperative handling of the oral anticoagulant therapy differs according to the periprocedural bleeding risk. Patients requiring a procedure with a minor risk for bleeding do not need to pause their anticoagulant therapy. For procedures with an increased risk for perioperative bleeding, the anticoagulant therapy should be adequately paused. For patients on a coumarin derivative with a high risk for a thromboembolic event, a perioperative bridging therapy with a low molecular weight heparin is recommended. Due to an increased risk for perioperative bleeding in patients on a bridging therapy, it is not recommended in patients with a low risk for thromboembolism. For patients taking a non-vitamin K oral anticoagulant, a bridging therapy is not recommended due to the fast onset and offset of the medication.

Abstract
Background Due to increasing use of new oral anticoagulants (NOACs), clinicians are faced more and more frequently with clinical issues related to these drugs. Objective The objective of this publication is to make practical suggestions for the perioperative management of NOACs as well as for their handling in overdoses and bleedings. Recommendations In elective surgery and creatinine clearance ≥ 50 ml/min, a NOAC should be discontinued 24-36 h before the intervention, and even earlier in case of reduced kidney function. In emergency interventions that cannot be delayed, the management is dependent on the NOAC plasma levels. With levels ≤ 30 ng/ml, surgery can be performed. With levels >30 ng/ml, reversal agents should be considered. In low bleeding risk surgery, NOACs can be re-started 24 h after the intervention, which is prolonged to 48-72 h after surgery with high bleeding risk. In case of NOAC overdose and minor bleedings, temporary discontinuation and supportive care are usually sufficient to control the situation. In severe or life-threatening bleedings, nonspecific and specific reversal agents should be considered.

Residual rivaroxaban exposure after discontinuation of anticoagulant therapy in patients undergoing cardiac catheterization. Eur J Clin Pharmacol 2018; 74:611-618.

Abstract
PURPOSE Patients treated with direct oral anticoagulants (DOACs) frequently undergo interventional procedures requiring temporary discontinuation of anticoagulant therapy. Little is known about remaining peri-procedural exposure to rivaroxaban in real-world patients. METHODS Fifty-six patients with rivaroxaban treatment and scheduled cardiac catheterization were included in this prospective, observational, and single-center study. Rivaroxaban concentrations were determined by LC-MS/MS and a chromogenic anti-Xa assay. Population pharmacokinetic modeling was carried out on LC-MS/MS concentration data using NONMEM software, and results were applied to Monte Carlo simulations to predict appropriate rivaroxaban discontinuation intervals. RESULTS Rivaroxaban concentrations ranged from <LLOQ to 300.6 ng/ml at the time of admission to hospital and from <LLOQ to 55.5 ng/ml at the beginning of the procedure. Times since last rivaroxaban intake were (mean ± SD) 51.0 ± 31.7 h (admission) and 85.5 ± 36.8 h (start catheterization). LC-MS/MS and anti-Xa assay results were in good agreement (r = 0.958); however, the anti-Xa assay may underestimate low rivaroxaban concentrations and overestimate rivaroxaban exposure when performed on plasma samples contaminated with heparins. Pharmacokinetics of rivaroxaban were adequately described, and simulations predicted that 95% of patients will have rivaroxaban concentrations ≤ 28.4 ng/ml (15 mg dose group) and ≤ 31.9 ng/ml (20 mg dose group) after 48 h of discontinuation. CONCLUSIONS In the majority of patients, rivaroxaban plasma concentrations dropped below 30 ng/ml after 48 h of treatment discontinuation which is considered hemostatically safe before surgery with high bleeding risk. For accurate determination of low rivaroxaban concentrations, LC-MS/MS is the preferred choice.
