Abstract
OBJECTIVES Lumbar puncture (LP) is fundamental for diagnosis and treatment; however, some parents do not provide consent for their children to undergo the procedure, which can make diagnosis and determination of the optimal treatment difficult. The present study aimed to describe the level of knowledge and attitudes toward LP of parents whose children were scheduled to undergo the procedure. METHODS A prospective cross-sectional descriptive study of a convenience sample of parents of 84 children aged 2 months to 17 years scheduled for LP at a single academic children's hospital between 2015 and 2017. Parents were administered a written survey and interviewed by a physician other than the person who did the LP. Data on parental level of knowledge and attitudes regarding LP, in addition to reasons for refusal, were collected.The parents of 84 patients scheduled for LP due to various indications were administered a face-to-face survey interview. The survey was used to collect parental demographic data, as well as opinions and knowledge about LP and postinterventional complications. RESULTS The mean age of the 84 patients (57% male and 43% female) was 6.4 ± 5.17 years. Lumbar puncture was planned for the presumptive diagnosis of neurological disease in 45.25% of the patients, central nervous system infection in 45.25%, and acute encephalopathy in 9.5%. Among the parents, 65% (n = 55) had no knowledge or attitude about LP prior to the survey interview. The most common parental concern related to LP was paralysis (25%), followed by infertility (2%), mental retardation (1%), and disease progression (1%). Only 4.7% of the parents did not provide consent for their child to undergo LP. CONCLUSIONS We found that most parents had little knowledge about LP, and the most common parental concern was paralysis. Despite this, in our study, only 5% of parents did not consent to LP.

Abstract
Spinal subarachnoid haemorrhage is a rare complication of spinal anaesthesia, especially following atraumatic lumbar puncture and in the absence of coagulopathies. The initial presentation of spinal subarachnoid haemorrhage is variable and paraplegia with full recovery within a few hours is rare. Bleeding can extend into the intracranial subarachnoid space, but there are only a few reports of symptomatic intracranial and spinal subarachnoid haemorrhage after spinal anaesthesia. We report co-existing spinal subarachnoid haemorrhage and intracranial subarachnoid haemorrhage after atraumatic spinal anaesthesia in a 69-year-old woman without a coagulopathy. The day after surgery she developed flaccid paraplegia that spontaneously resolved in a few hours. Magnetic resonance imaging demonstrated subarachnoid high signal intensity from T11-S2, consistent with spinal subarachnoid haemorrhage. On the same day the patient complained of severe headache which was later followed by diplopia. Neurological imaging studies revealed diffuse distribution of blood in the subarachnoid space but no intracranial vascular malformations. At the time of diagnosis spontaneous recovery of spinal symptoms had already begun and the clinical manifestations eventually resolved with conservative management. The possibility of an intracranial haemorrhage should always be considered when spinal subarachnoid haemorrhage is identified, even in cases of uncomplicated spinal anaesthesia in patients with no known risk factors for spinal haemorrhage.

Abstract
Spinal subarachnoid hematoma (SSH) following diagnostic lumbar puncture is very rare. Generally, SSH is more likely to occur when the patient has coagulopathy or is undergoing anticoagulant therapy. Unlike the usual complications, such as headache, dizziness, and back pain at the needle puncture site, SSH may result in permanent neurologic deficits if not properly treated within a short period of time. An otherwise healthy 43-year-old female with no predisposing factors presented with fever and headache. Diagnostic lumbar puncture was performed under suspicion of acute meningitis. Lumbar magnetic resonance imaging was performed due to hypoesthesia below the level of T10 that rapidly progressed after the lumbar puncture. SSH was diagnosed, and high-dose steroid therapy was started. Her neurological symptoms rapidly deteriorated after 12 hours despite the steroids, necessitating emergent decompressive laminectomy and hematoma removal. The patient’s condition improved after the surgery from a preoperative motor score of 1/5 in the right leg and 4/5 in the left leg to brace-free ambulation (motor grade 5/5) 3-month postoperative. The patient was discharged with no neurologic deficits. Critical complications such as SSH can be fatal. Therefore, a patient undergoing lumbar puncture must be carefully observed. A hematoma that convincingly compresses the spinal cord or cauda equina on imaging results requires early surgical decompression and hematoma removal.

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
Background: Lumbar puncture (LP) rarely results in complications such as spinal hematomas. However, it remains unclear if certain variables increase likelihood of these events, or if surgical intervention improves outcome. Methods: In addition to two clinical vignettes, we evaluated the post-1974 literature for cases of spinal hematoma and subsequent intervention. Based on our compilation of data, we evaluated outcome relative to numerous distinct variables. Results: Based on 35 LP-related spinal hematoma cases in the post-1974 literature and our encounters, we found 28.6% of patients presenting with preexisting coagulopathy had poor outcomes regardless of intervention, relative to 14.3% of patients without coagulopathy; a highly significant difference (P = 0.02). Once diagnosed, 21 patients were treated surgically and 14 nonsurgically. Of the 60% surgical patients, 57.1% had good outcomes, and 42.9% had poor outcomes within 12 months. Of 40% nonsurgical patients, 57.1% had good outcomes and 42.9% had poor outcomes. Results in these groups were not statistically different. Conclusions: We found a significant correlation between preexisting coagulopathy and poor neurological outcome irrespective of intervention. However, outcomes for these patients may be confounded by comorbidities including underlying conditions contributing to their coagulopathy. No significant correlation between type of surgical intervention and good outcome was found, possibly attributable to the paucity of details in existing case reports and the difficulty defining the degree of spinal cord compromise from a given lesion. Despite our findings, emergent neurosurgical intervention may be beneficial for the management of complications such as cauda equina syndrome secondary to intrathecal spinal hematoma.

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
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
OBJECTIVE Little is known about practice patterns regarding shoulder glucocorticoid injections in patients taking antiplatelet drugs or vitamin K antagonists. The objective of this study was to collect relevant data among rheumatologists in France. METHODS We conducted a postal questionnaire survey among 2015 rheumatologists. RESULTS We received 1018 completed questionnaires (response rate, 1018/2015, 50.5%). The proportion of rheumatologists who discontinued drugs with antithrombotic effects prior to shoulder injections varied across drugs, as follows: nonsteroidal antiinflammatory drugs (NSAIDs), 2.6%; dipyridamole, 7.5%; aspirin, 9%; ticlopidine, 25%; clopidogrel, 28%; and vitamin K antagonists, 74%. Among rheumatologists who discontinued vitamin K antagonist therapy, 82% prescribed replacement therapy with low-molecular-weight heparin. Time from discontinuation to injection was not consistently appropriate to the duration of drug effects. Prior to the injection, hemostasis tests were obtained by 1% of rheumatologists for patients on NSAIDs, 6% for those on clopidogrel, and 65% for those on vitamin K antagonists. Only 1% of rheumatologists had observed bleeding events in patients on aspirin, compared to 10% in patients on vitamin K antagonists. The mean number of shoulder glucocorticoid injections per rheumatologist per month was 19.6; 4% of rheumatologists routinely obtained hemostasis tests before shoulder injections. CONCLUSION Considerable variations were found among rheumatologists regarding practice patterns for performing shoulder glucocorticoid injections. This variability reflects the absence of official guidelines. The GREP is working with French hematologists to develop clinical practice guidelines.

Abstract
More efficacious anticoagulant and antiplatelet agents have been introduced in vascular medicine and in the prevention of perioperative venous thromboembolisms. Patient management should be guided by familiarity with the pharmacology of coagulation-altering drugs and by consensus statements. The present paper reviews recommendations from the Austrian Task Force for Perioperative Coagulation which are based on thorough evaluation of the available pharmacological information and case reports. The consensus statement focuses on neuraxial and peripheral techniques and is designed to encourage safe and quality patient care.

Abstract
Acute neurologic deterioration is not a rare event in the surgical decompression for thoracic spinal stenosis. We report a case of transient paraparesis after decompressive laminectomy in a 50-yr-old male patient with multi-level thoracic ossification of the ligamentum flavum and cervical ossification of the posterior longitudinal ligament. Decompressive laminectomy from T9 to T11 was performed without gross neurological improvement. Two weeks after the first operation, laminoplasty from C4 to C6 and additional decompressive laminectomies of T3, T4, T6, and T8 were performed. Paraparesis developed 3 hr after the second operation, which recovered spontaneously 5 hr thereafter. CT and MRI were immediately performed, but there were no corresponding lesions. Vascular compromise of the borderlines of the arterial supply by microthrombi might be responsible for the paraparesis.

Abstract
UNLABELLED We prospectively studied 1035 individuals undergoing 1214 epidural steroid injections to determine the risk of hemorrhagic complications. A history of bruising or bleeding was present in 176 (15%) patients. A platelet count was assessed in 77 patients before the epidural steroid injection; none was less than 100 x 10(9)/L. Nonsteroidal antiinflammatory drugs (NSAIDs) were reported by 383 (32%) patients, including 34 patients on multiple medications. Aspirin was the most common NSAID and was noted by 158 patients, including 104 patients on 325 mg or less per day. There were no spinal hematomas (major hemorrhagic complications). Blood was noted during needle or catheter placement in 63 (5.2%) patients (minor hemorrhagic complications). NSAIDs did not increase the frequency of minor hemorrhagic complications. However, increased age, needle gauge, needle approach, needle insertion at multiple interspaces, number of needle passes, volume of injectant, and accidental dural puncture were all significant risk factors for minor hemorrhagic complications. There were 42 patients with new neurologic symptoms or worsening of preexisting complaints that persisted more than 24 h after injection; median duration of the symptoms was 3 days (range, 1-20 days). Our results confirm those of previous studies performed in obstetric and surgical populations that document the safety of neuraxial techniques in patients receiving NSAIDs. We conclude that epidural steroid injection is safe in patients receiving aspirin-like antiplatelet medications. Minor worsening of neurologic function may occur after epidural steroid injection and must be differentiated from etiologies requiring intervention. IMPLICATIONS Previous studies performed in obstetric and surgical populations have demonstrated that antiplatelet therapy does not increase the risk of spinal hematoma associated with spinal or epidural anesthesia and analgesia. We confirm the safety of epidural steroid injection in patients receiving aspirin-like medications.

Abstract
STUDY DESIGN Prospective, randomized, double-blind study. OBJECTIVE To assess the efficacy of ketorolac and bupivacaine in reducing postoperative pain after microsurgical lumbar discectomy. SUMMARY OF BACKGROUND DATA Microsurgical lumbar discectomy often is performed as an ambulatory procedure. Pain, nausea, and urinary retention may delay discharge. It was hypothesized that intraoperative ketorolac or bupivacaine would reduce postoperative pain as measured by morphine demand. METHODS After Institutional Review Board (IRB) approval and informed consent, 30 patients undergoing single-level microsurgical lumbar discectomy under general anesthesia randomly received either intravenous ketorolac, intramuscular bupivacaine, or placebo before wound closure. After surgery, all patients received intravenous, MSO4, patient-controlled analgesia. MSO4 demand was compared between groups at 30 minutes and at 1, 4, 8, 16, 20, and 24 hours after surgery by one-way ANOVA. Pre- and postoperative pain was assessed by using a standard scale and was correlated to postoperative MSO4 demand by Pearson correlation. Significance was assumed at P < 0.05. RESULTS There were no group differences in age, gender, weight, disc level, preoperative pain, or preoperative use of pain medication. Neither ketorolac nor bupivacaine decreased pain or nausea scores, MSO4 demand, or time to void and ambulation. Preoperative pain was significantly correlated to postoperative narcotic demand (r = 0.46, P < 0.01). Preoperative narcotic or NSAID use was not correlated to either preoperative pain scores or postoperative MSO4 requirement. CONCLUSIONS Neither ketorolac nor bupivacaine decreased the postoperative narcotic requirement in patients undergoing microsurgical lumbar discectomy. Postoperative narcotic requirements are increased in patients who are in severe pain before surgery, regardless of preoperative narcotic use.
