Abstract
BACKGROUND Laparoscopic gastrectomy is a common procedure for early gastric cancer treatment. Improving postoperative pain control enhances patient recovery after surgery. The use of multimodal analgesia can potentially enhance the analgesic effect, minimize side effects, and change the postoperative management. The purpose of this study was to evaluate and compare the efficacies of the use of patient-controlled intravenous analgesia with regular acetaminophen (PCIA + Ace) and patient-controlled thoracic epidural analgesia (PCEA) for postoperative pain control. METHODS We retrospectively collected the data of 226 patients who underwent laparoscopic distal gastrectomy (LDG) with delta-shaped anastomosis between 2016 and 2019. After 1:1 propensity-score matching, we compared 83 patients who used PCEA alone (PCEA group) with 83 patients who used PCIA + Ace (PCIA + Ace group). Postoperative pain was assessed using a numeric rating scale (NRS) with scores ranging from 0 to 10. An NRS score ≥ 4 was considered the threshold for additional intravenous rescue medication administration. RESULTS Although NRS scores at rest were comparable between the PCEA and PCIA + Ace groups, NRS scores of patients in the PCIA + Ace group during coughing or movement were significantly better than those of patients in the PCEA group on postoperative days 2 and 3. The frequency of additional rescue analgesic use was significantly lower in the PCIA + Ace group than in the PCEA group (1.1 vs. 2.7, respectively, p < 0.001). The rate of reduction or interruption of the patient-controlled analgesic dose was higher in the PCEA group than in the PCIA + Ace group (74.6% vs. 95.1%, respectively, p = 0.0002), mainly due to hypotension occurrence in the PCEA group. Physical recovery time, postoperative complication occurrence, and liver enzyme elevation incidence were not significantly different between groups. CONCLUSIONS PCIA + Ace can be safely applied without an increase in complications or deterioration in gastrointestinal function; moreover, PCIA + Ace use may provide better pain control than PCEA use in patients following LDG.

Abstract
BACKGROUND Bleeding is a potential complication after neuraxial and peripheral nerve blocks. The risk is increased in patients on antiplatelet and anticoagulant drugs. This joint guideline from the European Society of Anaesthesiology and Intensive Care and the European Society of Regional Anaesthesia aims to provide an evidence-based set of recommendations and suggestions on how to reduce the risk of antithrombotic drug-induced haematoma formation related to the practice of regional anaesthesia and analgesia. DESIGN A systematic literature search was performed, examining seven drug comparators and 10 types of clinical intervention with the outcome being peripheral and neuraxial haematoma. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used for assessing the methodological quality of the included studies and for formulating recommendations. A Delphi process was used to prepare a clinical practice guideline. RESULTS Clinical studies were limited in number and quality and the certainty of evidence was assessed to be GRADE C throughout. Forty clinical practice statements were formulated. Using the Delphi-process, strong consensus (>90% agreement) was achieved in 57.5% of recommendations and consensus (75 to 90% agreement) in 42.5%. DISCUSSION Specific time intervals should be observed concerning the adminstration of antithrombotic drugs both prior to, and after, neuraxial procedures or those peripheral nerve blocks with higher bleeding risk (deep, noncompressible). These time intervals vary according to the type and dose of anticoagulant drugs, renal function and whether a traumatic puncture has occured. Drug measurements may be used to guide certain time intervals, whilst specific reversal for vitamin K antagonists and dabigatran may also influence these. Ultrasound guidance, drug combinations and bleeding risk scores do not modify the time intervals. In peripheral nerve blocks with low bleeding risk (superficial, compressible), these time intervals do not apply. CONCLUSION In patients taking antiplatelet or anticoagulant medications, practitioners must consider the bleeding risk both before and after nerve blockade and during insertion or removal of a catheter. Healthcare teams managing such patients must be aware of the risk and be competent in detecting and managing any possible haematomas.

Abstract
BACKGROUND Despite a proven superior efficacy of prophylactic low-molecular-weight heparin (LMWH) over unfractionated heparin (UFH) in the majority of surgical specialties, chemoprophylactic techniques after spine surgery have not been established because of the fear of epidural hematomas with LMWH. OBJECTIVE To determine the efficacy of LMWH vs UFH in the prevention of venous thromboembolism (VTE) events, balanced against the risk of epidural hematoma. METHODS This is the first matched cohort design that directly compares prophylactic LMWH to UFH after spine surgery for degenerative/deformity pathologies at a tertiary academic center. Prospectively collected patients receiving prophylactic LMWH and a historical cohort of patients receiving prophylactic UFH (prior to 2017) were matched in 1:1 ratio based on age ±5 yr, American Society of Anesthesiologists classification, location in the spinal column, and type of surgery. RESULTS Of 562 patients, VTE events equaled 1.4% (n = 8): 1.4% (n = 4) with LMWH was exactly equal to 1.4% (n = 4) with UFH. Epidural hematomas reached 0.8% (n = 5): 1.4% (n = 4) with UFH vs 0.3% (n = 1) with the LMWH (P = .178). Utilizing adjusted odds ratio (ORadj), the type of chemoprophylaxis after spine surgery failed to predict VTE events. Similarly, the chemoprophylactic technique failed to predict epidural hematoma in the multivariable regression analysis, although UFH trended toward a higher complication rate (ORadj = 3.15 [0.48-20.35], P = .227). CONCLUSION Chemoprophylactic patterns failed to predict VTE. Although no differences in epidural hematoma rates were detected, our analysis does highlight a trend toward a safer profile with LMWH vs UFH. LMWH may be a safe alternative to UFH in spine surgery.

Abstract
RATIONALE Epidural hematomas can develop following intrathecal puncture, spinal vascular malformation, or spontaneous hemorrhage. Prompt recognition of symptoms and referral to neurosurgical services are crucial for recovery. We report a rare case of delayed removal of an epidural hematoma that resulted in good patient outcomes. PATIENT CONCERNS A 69-year-old woman weighing 58 kg presented with back pain that had persisted for 12 years. Her medical history was notable for hypertension. Cervical computed tomography angiography indicated a giant abdominal aortic aneurysm measuring 11.58 × 17.34 × 13.00 cm in her abdominal cavity. Stent graft implantation was scheduled by the interventional therapy group to treat her abdominal aortic aneurysm under single-dose spinal anesthesia. Postoperatively, the patient complained of numbness and swelling of her lower extremities, with progressive paralysis developing in both legs accompanied with sensory disturbances. DIAGNOSES Delayed magnetic resonance imaging detected an epidural hematoma. INTERVENTIONS Eighty hours after the onset of sensorimotor symptoms, lumbar decompression and removal of the hematoma were performed via laminectomy under general anesthesia. OUTCOMES The patient was discharged 2 months after the operation with a 3/5 score on the Muscle Strength Grading System. LESSONS Laminectomy may be effective in achieving a good prognosis despite a considerable delay in diagnosis.

Abstract
Abstract
Background
Bleeding into the vertebral canal causing a spinal haematoma (SH) is a rare but serious complication to central neuraxial blocks (CNB). Of all serious complications to CNBs such as meningitis, abscess, cardiovascular collapse, and nerve injury, neurological injury associated with SH has the worst prognosis for permanent harm. Around the turn of the millennium, the first guidelines were published that aimed to reduce the risk of this complication. These guidelines are based on known risk factors for SH, rather than evidence from randomised, controlled trials (RCTs). RCTs, and therefore meta-analysis of RCTs, are not appropriate for identifying rare events. Analysing published case reports of rare complications may at least reveal risk factors and can thereby improve management of CNBs. The aims of the present review were to analyse case reports of SH after CNBs published between 1994 and 2015, and compare these with previous reviews of case reports.
Methods
MEDLINE and EMBASE were used for identifying case reports published in English, German, or Scandinavian languages, using appropriate search terms. Reference lists were also scrutinised for case reports. Twenty different variables from each case were specifically searched for and filled out on an Excel spreadsheet, and incidences were calculated using the number of informative reports as denominator for each variable.
Results
Altogether 166 case reports on spinal haematoma after CNB published during the years between 1994 and 2015 were collected. The annual number of case reports published during this period almost trebled compared with the two preceding decades. This trend continued even after the first guidelines on safe practice of CNBs appeared around year 2000, although more cases complied with such guidelines during the second half of the observation period (2005–2015) than during the first half. Three types of risk factors dominated:(1)Patient-related risk factors such as haemostatic and spinal disorders, (2) CNB-procedure-related risks such as complicated block, (3) Drug-related risks, i.e. medication with antihaemostatic drugs.
Conclusions and implications
The annual number of published cases of spinal haematoma after central neuraxial blocks increased during the last two decades (1994–2015) compared to previous decades. Case reports on elderly women account for this increase.Antihaemostatic drugs, heparins in particular, are still major risk factors for developing post-CNB spinal bleedings. Other risk factors are haemostatic and spinal disorders and complicated blocks, especially “bloody taps”, whereas multiple attempts do not seem to increase the risk of bleeding. In a large number of cases, no risk factor was reported. Guidelines issued around the turn of the century do not seem to have affected the number of published reports. In most cases, guidelines were followed, especially during the second half of the study period. Thus, although guidelines reduce the risk of a post-CNB spinal haematoma, and should be strictly adhered to in every single case, they are no guarantee against such bleedings to occur.

Abstract
We report a case of accidental clopidogrel administration in a patient receiving ongoing epidural analgesia postoperatively. The epidural catheter was removed 7 hours after the clopidogrel dose without incident. The onset of inhibition of adenosine diphosphate-induced platelet aggregation in healthy individuals has been reported at 12 to 24 hours after administration of a single 75-mg dose of clopidogrel. This case demonstrates the importance of understanding clopidogrel's pharmacology to avoid ordering unnecessary tests, which may delay catheter removal. Consideration of appropriate testing and limitations in the context of unintentional antiplatelet administration with indwelling neuraxial catheters is discussed.

Abstract
PURPOSE Epidural hematoma is a rare but serious complication of epidural anesthesia. We report a case of epidural hematoma, occurring in an obstetric patient after the epidural catheter had been withdrawn accidentally after an episode of hemorrhagic shock leading to a hypocoagulable state. CLINICAL FEATURES A patient had the epidural catheter inserted during labour when coagulation was normal. She had a postpartum hemorrhage with alteration of coagulation (platelets 16 x 10(-9) x L(-1), thrombin time: 85 sec. Vital signs returned to normal after a general anesthetic, transfusion of blood products, volume repletion and ligation of hypogastric arteries. It was then noticed that the epidural catheter had been withdrawn inadvertently while the patient was hypocoagulable. The patient then developed neurological signs consistent with spinal cord compression due to an epidural hematoma. A hematoma extending from T3 to L5 was diagnosed by magnetic resonance imaging. Because the cord had minimal compression, no specific action was undertaken, other than clinical and radiological follow-up. There were no long-term sequelae. CONCLUSION In the presence of an epidural hematoma, surgery for emergency cord decompression is usually required. Another option that receives increasing attention is to monitor neurological function, but the indications for this expectant treatment are not well defined.

Abstract
Clopidogrel is an antiplatelet drug that is used in patients who have had previous cerebrovascular events, acute coronary syndromes, or who underwent percutaneous coronary interventions (PCI) with bare metal or drug-eluting stents. About 5% of patients who undergo PCI have to undergo non-cardiac surgery within 1 year of coronary stent implantation. Patients who receive clopidogrel may be at increased risk of bleeding complications during surgery. The risk of coronary thrombosis after non-cardiac surgery increases, especially when surgery is performed early after stenting, and particularly when antiplatelet agents are withdrawn before surgery. The decision to continue or withhold clopidogrel should reflect a balance of the consequences of perioperative hemorrhage versus the risk of perioperative vascular complications. Close communication among surgeons, anesthesiologists, and cardiologist is necessary to minimize both adverse cardiac risk and surgical risk in those patients.

Abstract
The actual incidence of neurologic dysfunction resulting from hemorrhagic complications associated with neuraxial blockade is unknown. Although the incidence cited in the literature is estimated to be less than 1 in 150,000 epidural and less than 1 in 220,000 spinal anesthetics, recent epidemiologic surveys suggest that the frequency is increasing and may be as high as 1 in 3000 in some patient populations.Overall, the risk of clinically significant bleeding increase with age,associated abnormalities of the spinal cord or vertebral column, the presence of an underlying coagulopathy, difficulty during needle placement,and an indwelling neuraxial catheter during sustained anticoagulation( particularly with standard heparin or low-molecular weight heparin). The need for prompt diagnosis and intervention to optimize neurologic outcome is also consistently reported. In response to these patient safety issues, the American Society of Regional Anesthesia and Pain Medicine (ASRA) convened its Third Consensus Conference on Regional Anesthesia and Anticoagulation. Practice guidelines or recommendations summarize evidence-based reviews. However, the rarity of spinal hematoma defies a prospective randomized study, and there is no current laboratory model. As a result,the ASRA consensus statements represent the collective experience of recognized experts in the field of neuraxial anesthesia and anticoagulation. These are based on case reports, clinical series, pharmacology,hematology, and risk factors for surgical bleeding. An understanding of the complexity of this issue is essential to patient management.

Abstract
The widespread use of central neuraxial block (CNB) and the prevalence of anticoagulation for different indications have led to an inevitable overlap between the two. The most serious complication of CNB in anticoagulated patients is the risk of spinal/epidural haematoma. Performing CNB in these patients is a complex decision that should take into account the twin risks of bleeding and venous/arterial thrombosis if anticoagulation therapies were to be stopped. Various guidelines have been issued to achieve normal haemostasis and thus allow safe administration of CNB. However, the evidence base for many such recommendations is weak, relying mainly on case reports, small studies and pharmacokinetics of the drugs. Given these limitations it is crucial to fully assess individual risk factors and understand anticoagulant pharmacokinetics in order to appropriately set time intervals for catheter insertion/removal. This paper will review traditional and newer anticoagulation/antiplatelet therapies with a view to improving the management of anticoagulated patients undergoing CNB.

Abstract
BACKGROUND Central neuraxial blocks (CNBs) for surgery and analgesia are an important part of anaesthesia practice in the Nordic countries. More active thromboprophylaxis with potent antihaemostatic drugs has increased the risk of bleeding into the spinal canal. National guidelines for minimizing this risk in patients who benefit from such blocks vary in their recommendations for safe practice. METHODS The Scandinavian Society of Anaesthesiology and Intensive Care Medicine (SSAI) appointed a task force of experts to establish a Nordic consensus on recommendations for best clinical practice in providing effective and safe CNBs in patients with an increased risk of bleeding. We performed a literature search and expert evaluation of evidence for (1) the possible benefits of CNBs on the outcome of anaesthesia and surgery, for (2) risks of spinal bleeding from hereditary and acquired bleeding disorders and antihaemostatic drugs used in surgical patients for thromboprophylaxis, for (3) risk evaluation in published case reports, and for (4) recommendations in published national guidelines. Proposals from the taskforce were available for feedback on the SSAI web-page during the summer of 2008. RESULTS Neuraxial blocks can improve comfort and reduce morbidity (strong evidence) and mortality (moderate evidence) after surgical procedures. Haemostatic disorders, antihaemostatic drugs, anatomical abnormalities of the spine and spinal blood vessels, elderly patients, and renal and hepatic impairment are risk factors for spinal bleeding (strong evidence). Published national guidelines are mainly based on experts' opinions (weak evidence). The task force reached a consensus on Nordic guidelines, mainly based on our experts' opinions, but we acknowledge different practices in heparinization during vascular surgery and peri-operative administration of non-steroidal anti-inflammatory drugs during neuraxial blocks. CONCLUSIONS Experts from the five Nordic countries offer consensus recommendations for safe clinical practice of neuraxial blocks and how to minimize the risks of serious complications from spinal bleeding. A brief version of the recommendations is available on http://www.ssai.info.

Abstract
BACKGROUND Temporary interruption of long-term anticoagulation and antiplatelet therapy during surgical procedures exposes patients to thrombotic risk. Continuation of these agents, however, is associated with an increased risk of bleeding. Managing anticoagulation can be a particular challenge in the emergency setting. METHODS A literature review of published articles sourced using the keywords heparin, warfarin, perioperative, antiplatelet, aspirin and surgery was undertaken. A management plan for all likely situations was developed. RESULTS AND CONCLUSION Based on an individual assessment of risk factors for arterial or venous thromboembolism and the risk of perioperative bleeding, it is possible to form an anticoagulant and antiplatelet management plan likely to achieve a low incidence of bleeding and thrombosis. A multidisciplinary approach is desirable.

Abstract
BACKGROUND : Because of its irreversible nature, Plavix (clopidogrel) has become a double edged sword in the care of some of our sickest patients, particularly when surgical intervention is required. Platelets exposed to a single dose of clopidogrel are affected for the remainder of their lifespan and recover normal platelet function at a rate consistent with platelet turnover, which is within 5 days to 7 days (1-3) with the generation of new platelets not influenced by the drug; however, delay of surgical fixation for orthopedic patients, particularly patients with hip fractures may lead to increased morbidity and mortality. METHODS : A Web-based survey was created and administered to the program directors of academic orthopedic surgery programs. RESULTS : Seventy-three percent of orthopedic residency programs responded that waiting 3 days or less for urgent but nonemergent operative interventions on patients on clopidogrel is acceptable with 23% feeling that no delay at all is necessary. For emergent surgery, the vast majority of programs 66 (89%) reported no delay to the operating room for patients on clopidogrel. CONCLUSIONS : The majority of orthopedic surgery residency programs who responded to the survey wait less than 3 days for urgent surgery and do not delay surgery for emergency cases for patients on clopidogrel. At this point we feel that an early intervention that occurs within approximately 2 days, with the acceptance of the possibility of increased blood loss is in the patient's best interest. Based on the reviewed physiology, a perioperative platelet transfusion may be of some benefit as the transfused platelets would be effective in forming a viable plug.

Abstract
PURPOSE To assess the risk of surgical delay in elderly hip fracture patients on anti-platelet agents. METHODS Records of 180 patients aged over 65 years with either an intertrochanteric or femoral neck fracture were reviewed. The clopidogrel group included 10 patients on clopidogrel alone and 11 others on clopidogrel and aspirin, whereas the control group included 69 on aspirin alone and the remaining 90 not on any anti-coagulants. The 2 groups were compared with regard to time to surgery, preoperative American Society of Anesthesiologists (ASA) score, pre- and post-operative haemoglobin levels, in-patient complication rates, duration of hospital stay, and 30-day mortality. RESULTS In the clopidogrel and control groups respectively, the mean times to surgery were 7.2 and 2.1 days (p=0.03, t-test), the mean preoperative ASA scores were 3.35 and 2.8 (p=0.29, t-test), the mean preoperative haemoglobin levels were 119 and 115 g/l (p=0.5, t-test), the mean postoperative haemoglobin levels were 98 and 96 g/l (p=0.68, t-test), the mean durations of hospital stay were 7.4 and 3.1 days (p=0.02, t-test). The 30-day mortalities were 6/21 (29%) and 6/159 (4%) [p=0.0003, Fisher's exact test]. CONCLUSION Surgical delay in elderly patients on anti-platelet agents with hip fracture was associated with higher mortality. Despite the risk of increased blood loss, we suggest early surgery be carried out by an experienced surgeon to expedite the operating time. Pooled platelets should be given intravenously one to 2 hours preoperatively.

Abstract
The utility of interventional cardiology has developed significantly over the last two decades with the introduction of coronary angioplasty and stenting, with the associated antiplatelet medications. Acute coronary stent occlusion carries a high morbidity and mortality, and the adoption of therapeutic strategies for prophylaxis against stent thrombosis has major implications for surgeons and anaesthetists involved in the management of these patients in the perioperative period. Currently, there is limited published information to guide the clinician in the optimal care of patients who have had coronary stents inserted when they present for non-cardiac surgery. This review examines the available literature on the perioperative management of these patients. A number of key issues are identified: the role of surgery vs percutaneous coronary intervention for coronary revascularization in the preoperative period; the different types of coronary stents currently available; the emerging issues related to drug-eluting stents; the pathophysiology of coronary stent occlusion; and the recommended antiplatelet regimes that the patient with a coronary stent will be receiving. The role of preoperative platelet function testing is also discussed, and the various available tests are listed. Appropriate management by all the clinicians involved with patients with coronary stents undergoing a variety of non-cardiac surgical procedures is essential to avoid a high incidence of postoperative cardiac mortality and morbidity. The review examines the evidence available for the perioperative strategies aimed at reducing adverse outcomes in a number of different clinical scenarios.

Abstract
The hemorrhagic side effects associated with the use of clopidogrel are within the acceptable range and occur mainly at skin or gastrointestinal sites. We report a case of spontaneous spinal epidural hematoma (SSEH) in a 60-yr-old woman who was treated with clopidogrel for frequent transient ischemic attacks. To our knowledge, this is the second reported case of clopidogrel-induced SSEH. The patient's symptoms and past history of clopidogrel use suggested the diagnosis and made the procedure proceed quickly to operate SSEH 9 hr after the onset of paraplegia. The outcome was excellent. Therefore, with the popularity of antiplatelet prescription, physicians should keep in mind and urgently treat this unusual but critical side effect.

Abstract
The wide use of anticlotting drugs by patients scheduled for surgery is a challenge for the anaesthesiologist when considering a regional anaesthesia technique. This practice seems safe if there is an appropriate management based on safety intervals established according to the pharmacology of the drug and the regional technique. Some anaesthesiology societies have published recommendations for the safe practice of regional anaesthesia with the simultaneous use of anticoagulants (heparin, low molecular weight heparins, oral anticoagulants (OA), fondaparinux and others) and antiplatelet agents (aspirin, clopidogrel, ticlopidine, argatroban and others). One of the most recent guidelines has been published by the Spanish Society of Anaesthesia and Critical Care. This article reviews these recommendations and compares them with others published in the last years. The recommendations are similar, but some interesting differences can be observed and need to be considered. A European consensus in this setting would probably be necessary.

Abstract
PURPOSE OF REVIEW The aim of this article is to review current practice of spinal anesthesia regarding technique and medication use; review recent applications of spinal anesthesia to subspecialty care in outpatient, cardiac, and obstetrical anesthesia; and update risk assessment associated with spinal anesthesia. RECENT FINDINGS Epidural volume extension enhances the spread of local anesthetics using a combined spinal-epidural technique. Chloroprocaine has become the agent of choice at some institutions. The growth in both the number and complexity of ambulatory surgery procedures has redefined the role of spinal anesthesia for outpatients. The 27-gauge Whitacre spinal needle is associated with a lower incidence of post-dural puncture headaches. Retrospective reviews can predict the incidence of rare complications such as neurologic injury and cardiac arrest. SUMMARY Innovations in technology, equipment, and needle design improved safety and decreased complication rates from spinal anesthesia. The increased popularity of ambulatory surgical procedures has resulted in more frequent use of spinal anesthesia. Intrathecal narcotic analgesia is used increasingly in fast-tracking cardiac surgical protocols. Modern anesthetic and analgesic techniques include resurgence of older agents (2-chloroprocaine) as well as new agents (levobupivacaine and ropivacaine) that are used in conjunction with adjuvant intrathecal medications (opioids, vasopressors, and alpha-2 adrenergic agonists). Surgical thromboprophylaxis and the increased use of anticoagulants in patients with cardiovascular disease have challenged anesthesiologists to update clinical guidelines to minimize the risk of hemorrhagic complications such as epidural hematoma. The risk/benefit ratio of spinal anesthesia should be individualized. The continued popularity of spinal anesthesia is due to the safety, effectiveness and efficiency of this technique.

Abstract
A large number of patients undergoing elective surgical procedures already take routine medication preoperatively. The majority of these patients use drugs for therapy of preexisting cardiovascular, pulmonary or endocrinological diseases which are independent of the planned surgical procedure. The number and type of preoperative drug therapy are correlated to age, gender and co-morbidity of the patients. Furthermore, patients with higher ASA-classes usually take more drugs, as they suffer from several medical diseases. Information about the perioperative handling of routine drug therapy is important for the planning of anaesthesia and surgery. A close cooperation of all medical specialities involved is necessary, in particular when patients take anticoagulants or other substances which should be withdrawn or replaced. This review focuses on the handling of routine preoperative medication by the anaesthesiologist in the light of available literature.
