Orthogeriatric co-management for the care of older subjects with hip fracture: recommendations from an Italian intersociety consensus.

BACKGROUND: Health outcomes of older subjects with hip fracture (HF) may be negatively influenced by multiple comorbidities and frailty. An integrated multidisciplinary approach (i.e. the orthogeriatric model) is, therefore, highly recommended, but its implementation in clinical practice suffers from the lack of shared management protocols and poor awareness of the problem. The present consensus document has been implemented to address these issues. AIM: To develop evidence-based recommendations for the orthogeriatric co-management of older subjects with HF. METHODS: A 20-member Expert Task Force of geriatricians, orthopaedics, anaesthesiologists, physiatrists, physiotherapists and general practitioners was established to develop evidence-based recommendations for the pre-, peri-, intra- and postoperative care of older in-patients (≥ 65 years) with HF. A modified Delphi approach was used to achieve consensus, and the U.S. Preventive Services Task Force system was used to rate the strength of recommendations and the quality of evidence. RESULTS: A total of 120 recommendations were proposed, covering 32 clinical topics and concerning preoperative evaluation (11 topics), perioperative (8 topics) and intraoperative (3 topics) management, and postoperative care (10 topics). CONCLUSION: These recommendations should ease and promote the multidisciplinary management of older subjects with HF by integrating the expertise of different specialists. By providing a convenient list of topics of interest, they might assist in identifying unmet needs and research priorities.

Management of hip fracture in the older people: rationale and design of the Italian consensus on the orthogeriatric co-management.

BACKGROUND: Hip fracture (HF) is a burdening health problem in older people. The orthogeriatric approach has been shown to favour functional recovery and reduce mortality, but its implementation in clinical practice cannot rely upon shared management protocols and greatly varies among different healthcare systems. Here, we present the rationale and design of the Italian consensus document on the management of HF in older people. METHODS: A panel of multidisciplinary experts from ten Italian scientific societies involved in the care of HF and including geriatricians, orthopaedics, anaesthesiologists, physiatrists and general practitioners, will join to establish the content validity of a list of statements. A Delphi consensus methodology will be applied to obtain the opinions of the panel and to provide the final recommendations. OBJECTIVES: The document will include indications on the following relevant topics: (1) optimal care path of older subjects with HF; (2) management of comorbidities and pre-operative alteration of physiological parameters; (3) management of selected categories of patients at expected increased risk of adverse outcomes; (4) continuity of care out of hospital; (5) screening and correction of risk factors for HF in older subjects; (6) information and divulgation of shared management strategies. The objective of the consensus will be to inform clinicians, patients, researchers, and health policy makers about the best management strategies for HF in older people and their inherent limitations, thus facilitating communication between stakeholders and promoting the most cost/effective models of care.

Rectus abdominis muscle innervation: an anatomical study with surgical implications in diep flap harvesting.

PURPOSE: To improve the current knowledge of rectus abdominis innervation, so as to identify a safe area where the vascular pedicle should be dissected to reduce the risk of nerve damage during deep inferior epigastric perforator (DIEP) flap harvesting. METHODS: Ten abdominal wall dissections were performed. Perforating arteries were identified and classified into nerve-related perforators and non-nerve-related perforators depending on the presence of nerve branches crossing vessels. The width of rectus abdominis and the distance between perforators and lateral edge of rectus abdominis muscle were measured. In contralateral hemi-abdomen, full-thickness specimens were sampled for microscopical analysis. RESULTS: Nerves enter the rectus sheath piercing the lateral edge (60% of cases) or the posterolateral surface of the sheath (40% of cases). They enter the rectus abdominis muscle at a mean distance of 4.3 cm from the lateral margin of the sheath. Within rectus abdominis, nerves have a mean thickness of 200.3 µm and split into 2-4 sensitive and 2-4 muscular branches. Close relationship between muscular branches and deep inferior epigastric artery perforators were shown. The mean distance between nerve-related perforators and the lateral edge of the rectus abdominis was of 3.26 ± 0.88 cm. The mean distance between non-nerve-related perforators and the lateral edge of the rectus abdominis was of 6.26 ± 0.90 cm. CONCLUSIONS: To spare nerves and reduce donor-site complications, a perforator located beyond an imaginary line of 3.26 ± 0.88 cm far from the lateral edge of rectus abdominis muscle should be included in the DIEP flap.

Dissemination of clinical and scientific practice through social media: a SIAARTI consensus-based document.

BACKGROUND: Dissemination of medical practice and scientific information through social media (SoMe) by clinicians and researchers is increasing. Broad exposure of information can promote connectivity within the scientific community, overcome barriers to access to sources, increase debate, and reveal layperson perspectives and preferences. On the other hand, practices lacking scientific evidence may also be promoted, laypeople may misunderstand the professional message, and clinician may suffer erosion of professional status. The aim of this project was to enhance awareness and advise the anesthesia community and clinicians at large about the potential risks advocate for responsible use of SoMe to disseminate information related to medical practices and knowledge. METHODS: A modified Delphi process with prespecified consensus criteria was conducted among a multidisciplinary panel of experts, including anesthesiologists-intensivists, clinical psychologists, and forensic medicine specialists. Six items were identified: Ethics and deontological principles, the practice of sharing information via social media, legal aspects, psychological aspects, self-promotion, and criteria for appropriate dissemination. Statements and rationales were produced and subjected to blinded panelists' votes. After reaching consensus, a document was written which then underwent external review by experts uninvolved in the consensus process. The project was promoted by the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI). RESULTS: Twelve statements were produced, and consensus was achieved for all. The panel concluded that the general principles guiding dissemination of professional information via SoMe must remain in line with the general principles of ethics, deontology, and scientific validity that guide the medical profession and science in general. Professional equity must be maintained while communicating via SoMe. Medical practices lacking support by scientific evidence should not be disseminated. Patients' informed consent must be obtained before dissemination of information, images, or data. Self-promotion must not be prioritized over any of these principles. CONCLUSIONS: When sharing medical practices and scientific information on SoMe, healthcare professionals are advised to act conscientiously and ethically. Local regulations should be adhered to. Institutional training on the potential risks and proper of SoMe for such purpose may contribute to preservation of professional integrity.

Camposampiero tubeless percutaneous nephrolithotomy (tPCNL): Easy, quick, effective, safe.

OBJECTIVES: To describe our technique to perform tubeless percutaneous nephrolithotomy (tPCNL) using hemostatic matrix (i.e. Floseal®) for the closure of the percutaneous tract, developed through the experience gained in our endourology specialized center. To evaluate the procedure efficacy and safety. METHODS: tPCNL performed in our center with Floseal® application from February 2017 to December 2019 were retrospectively reviewed. Clinical and surgical data were collected in order to evaluate the success of the procedure and possible complications. Camposampiero technique is reported in detail. RESULTS: Sixty-nine patients (45 males, mean age 58 years old) were included. In all patients the procedure was completed successfully and in 88% of subjects no further treatments were necessary; a low complication rate (6.9%) was reported. CONCLUSION: In our experience, tPCNL with Floseal application is feasible, safe, and effective.

The role of beta-blocker drugs in critically ill patients: a SIAARTI expert consensus statement.

BACKGROUND: The role of ß-blockers in the critically ill has been studied, and data on the protective effects of these drugs on critically ill patients have been repeatedly reported in the literature over the last two decades. However, consensus and guidelines by scientific societies on the use of ß-blockers in critically ill patients are still lacking. The purpose of this document is to support the clinical decision-making process regarding the use of ß-blockers in critically ill patients. The recipients of this document are physicians, nurses, healthcare personnel, and other professionals involved in the patient's care process. METHODS: The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) selected a panel of experts and asked them to define key aspects underlying the use of ß-blockers in critically ill adult patients. The methodology followed by the experts during this process was in line with principles of modified Delphi and RAND-UCLA methods. The experts developed statements and supportive rationales in the form of informative text. The overall list of statements was subjected to blind votes for consensus. RESULTS: The literature search suggests that adrenergic stress and increased heart rate in critically ill patients are associated with organ dysfunction and increased mortality. Heart rate control thus seems to be critical in the management of the critically ill patient, requiring careful clinical evaluation aimed at both the differential diagnosis to treat secondary tachycardia and the treatment of rhythm disturbance. In addition, the use of ß-blockers for the treatment of persistent tachycardia may be considered in patients with septic shock once hypovolemia has been ruled out. Intravenous application should be the preferred route of administration. CONCLUSION: ß-blockers protective effects in critically ill patients have been repeatedly reported in the literature. Their use in the acute treatment of increased heart rate requires understanding of the pathophysiology and careful differential diagnosis, as all causes of tachycardia should be ruled out and addressed first.

Buprenorphine added to levobupivacaine enhances postoperative analgesia of middle interscalene brachial plexus block.

PURPOSE: The aim of this study was to assess whether addition of epineural buprenorphine prolonged postoperative analgesia of middle interscalene brachial plexus block (MIB) with levobupivacaine. METHODS: One hundred and fifty consenting adult patients, scheduled for shoulder arthroscopic surgery for a rotator cuff tear under MIB with 29.5 ml of 0.75 % levobupivacaine, were randomized to receive additionally either saline or intramuscular buprenorphine 0.15 mg or epineural buprenorphine 0.15 mg. Onset of sensory and motor blocks, duration of postoperative analgesia, and consumption of postoperative analgesics were compared among the groups. RESULTS: There were significant (P < 0.05) differences in the onset and the duration of the sensory block and in the duration of postoperative analgesia. Duration of both sensory block and postoperative analgesia was longer (P < 0.05) in patients who had received epineural buprenorphine (856.1 ± 215.2 and 1,049.7 ± 242.2 min) than in patients who had received intramuscular buprenorphine (693.6 ± 143.4 and 820.3 ± 335.3 min) or saline (488.3 ± 137.6 and 637.5 ± 72.1 min). Requirement of postoperative rescue analgesics was lower in the epineural buprenorphine group than in the other two groups. Few complications occurred from MIB (<1 %) and none from buprenorphine. CONCLUSIONS: Epineural buprenorphine prolonged postoperative analgesia of MIB more effectively than intramuscular buprenorphine, which suggests that buprenorphine acts at a peripheral nervous system site of action.

Ultrasound-Guided PECS II + Serratus Plane Fascial Blocks Are Associated with Reduced Opioid Consumption and Lengths of Stay for Minimally Invasive Cardiac Surgery: An Observational Retrospective Study.

This study tested the hypothesis that pectoralis II (PECS II) + serratus plane blocks would reduce opioid consumption and improve outcomes compared with standard practice in minimally invasive cardiac surgery. A retrospective and observational study was realized in the intensive care unit (ICU) setting of "ICLAS GVM, Istitituto Clinico Ligure Alta Specialità, (Rapallo, Italy)", including adult patients who underwent right minithoracotomy for replacement/plastic aortic, mitral and tricuspid valve or atrial myxoma resection in cardiac surgery. Seventy-eight patients were extracted by the database and divided into two groups. Group 1 (41 patients) received ultrasound-guided PECS II + serratus plane blocks with Ropivacaine 0.25% 10 mL + 20 mL + 30 mL. Group 2 (37 patients) received intravenous opioids analgesia with morphine 20−25 mg/day or tramadol 200−300 mg/day. The primary outcomes were: the pain perceived: Critical-Care Pain Observation Tool (CPOT) score; the opioids consumption: mg morphine or tramadol, or µg sufentanyl administered; and mg paracetamol, toradol, tramadol or morphine administered as a rescue. The secondary outcomes were the hours of orotracheal intubation and of stay in ICU, and the number of episodes of nausea, vomiting, delayed awakening and respiratory depression. Group 1 vs. Group 2 consumed less opioids (Sufentanyl p < 0.0001; Morphine p < 0.0001), had a lower pain perceived (p = 0.002 at 6 h, p = 0.0088 at 12 h, p < 0.0001 at 24 h), need for rescue analgesia (p = 0.0005), episodes of nausea and vomiting (p = 0.0237) and intubation time and ICU stay (p = 0.0147 time of IOT, p < 0.0001 stay in ICU). Ultrasound-guided PECS II + serratus plane blocks demonstrated better than intravenous opioids analgesia in patients undergoing minimally invasive cardiac surgery.

Ultrasound-Guided Interpectoral and Pectoserratus Plane Blocks in Breast Surgery: An Alternative Option to General Anaesthesia in an Elderly Woman with a Complex Medical History.

With an incidence of over 1.5 million worldwide per annum, breast cancer continues to be the most common cancer affecting the female population. The main and most effective treatment in over 40% of these patients is a primary neoplasm resection. General anaesthesia, at times in association with loco-regional anaesthetics, is the most commonly used anaesthesia technique for radical mastectomies. Nausea, vomiting, and considerable postoperative pain, which are commonly experienced side effects and complications of general anaesthesia, tend, however, to augment most patients' post-surgical morbidity. A growing body of research has shown that loco-regional anaesthesia often used together with and, in some cases, in the substitution of general anaesthesia can be a safe, effective alternative. This work is a case report regarding a 94-year-old elderly patient who was anaesthetised during a left radical mastectomy using exclusively combined interpectoral and pectoserratus plane blocks.

Blocking around the transversalis fascia: behind the scene.

BACKGROUND: The transversalis fascia plane and the quadratus lomborum blocks target the branches of T12-L1 nerves and provide analgesia in patients undergoing surgery involving the corresponding dermatomes. The transversalis fascia is believed to contribute to determine the spread of local anesthetic in such blocks. Nonetheless, the anatomy of this fascia and its possible role in these blocks still have to be precisely defined. METHODS: We conducted a series of 10 dissections and full-thickness specimens were obtained from one side for the microscopic analysis. RESULTS: Macroscopic study showed failed to identify a distinguishable fascial structure between the fascia of the transversus abdominis muscle and the peritoneum. Microscopic examination showed the presence of a further fascial layer (0.1-0.2 mm), ascribable to transversalis fascia. Transversalis fascia and transversus abdominis epimysium posteriorly diverge: transversus epimysium goes posteriorly to quadratus lomborum to joint the oblique internal aponeurosis, while transversalis fascia continues in front to quadratus lomborum. So, a little fascial triangle (2-3 mm) is formed on the lateral border of quadratus lomborum, defined by transversalis fascia and transversus abdominis. Inside this triangle, T12 and L1 nerves are present. CONCLUSIONS: Considering the thinness of the transversalis fascia and the small size of the triangular space that contains the target nerves, this is most likely a virtual, ideal rather than realistic injection site. Accordingly, it is probable that the local anesthetic is injected in the much wider retroperitoneal space and reaches the nerves by spreading backwards through the thin transversalis fascia.

Ultrasonography and Italian anesthesiology: a national cross-sectional study.

PURPOSE: In recent years, ultrasound has seen a rapid development with numerous applications in anesthesia, intensive-care medicine, and pain medicine, increasing efficacy and safety of procedures. We investigated the prevalence of ultrasound use among Italian anesthetists. METHODS: A cross-sectional prevalence study was carried out on a sample of 735 anesthetists. The research was conducted during the ultrasound training in anesthesia and intensive care, in the Italian Associazione Anestesisti Rianimatori Ospedalieri - Emergenza Area Critica "SimuLearn®" training centre (Bologna, Italy). RESULTS: The overall prevalence of a dedicated ultrasound devices in the operating room was 70% [95% CI 66-73%], while 74% [95% CI 69-78%] in northern Italy, 61% [95% CI 52-68%] in southern Italy, and 70% [95% CI 63-77%] in central Italy, indicating a significant difference between the north and south of Italy. The prevalence of regular use of ultrasound was high for regional anesthesia and for central venous cannulation [82-95% CI 79-85%] and low for pain therapy procedures [7-95% CI 6-10%]. Multivariate logistic analysis showed that the presence of a dedicated ultrasound device and high expertise were factors associated with routine use of ultrasound for regional anesthesia in upper and lower limb blocks and in vascular access. CONCLUSION: The appropriate training in the use of ultrasound in anesthesia, intensive-care medicine, and pain therapy should be implemented in south of Italy to make uniform the widespread of ultrasonography in anesthesia, in all Italian regions.

Ultrasound-Guided Transversalis Fascia Plane Block: An Alternative Approach for Anesthesia in Inguinal Herniorrhaphy: A Case Report.

Ultrasound (US)-guided transversalis fascia plane block (TFPB) was first described by Hebbard as a technique for blockade of T12-L1 nerves. Although this technique appears similar to the quadratus lumborum 1 block, the point of injection is more caudal and anterior, specifically targeting ilioinguinal and iliohypogastric nerves. There are only few published data on US-guided TFPB demonstrating effective postoperative analgesia in iliac crest bone graft harvesting. We report the use of US-guided TFPB in a patient undergoing inguinal herniorrhaphy. Our experience suggests that this technique could represent a viable alternative to general anesthesia and standard regional techniques for inguinal hernia repair.

The Rise of New Alcoholic Games Among Adolescents and the Consequences in the Emergency Department: Observational Retrospective Study.

BACKGROUND: The links between the internet and teenager behavior are difficult situations to control and may lead to the development of new and excessive methods of drinking alcohol during alcoholic games. Findings indicate that reported cases are very useful sources for better understanding of alcoholic games, yielding successful measures promoting health among adolescents. Admittance of adolescents to hospital emergency departments (EDs) after consumption of excessive amounts of alcohol has become the norm in developed countries. The harmful effects of acute alcohol abuse are reported in this paper. OBJECTIVE: The aim of this work was to investigate the close connections between new drinking behaviors among adolescents and study the increase in new alcoholic games, together with the challenges that cause acute alcohol intoxication, the influence of the internet and social networks, and their consequences for public health services. METHODS: Data came from prehospital and intrahospital admissions attributable to alcohol consumption. From 2013 to 2015, 3742 patients were admitted to EDs due to acute alcohol intoxication: 830 of them were aged 15 to 30 years, and 225 were adolescents and young adults between 15 and 20 years who had been playing alcoholic games. Retrospectively, diagnostic data associated with extrahospital anamneses were selected by one of the hospital management information systems, Qlik. As a result of our previous experience, questionnaires and face-to-face interviews were performed at a later stage, when a clinical audit for intoxicated adolescent patients was described, with the overall goal of establishing a potential methodological workflow and adding important information to research carried out so far. RESULTS: Between 2013 and 2015, 830 young patients aged 15 to 30 years were admitted to EDs for acute alcohol intoxication. About 20% (166/830) of the sample confirmed that they had drunk more than 5 alcoholic units within 2 hours twice during the past 30 days as a result of binge drinking. Referring to new alcoholic games, 41% of the sample stated that they knew what neknomination is and also that at least one of their friends had accepted this challenge, describing symptoms such as vomiting, headache, altered behavior, increased talkativeness, and sociability. The median value of the weighted average cost of the diagnosis-related group relating to interventions provided by hospitals was the same for both genders, €46,091 (US $56,497; minimum €17,349 and maximum €46,091). CONCLUSIONS: Drinking games encourage young people to consume large quantities of alcohol within a short period of time putting them at risk of alcohol poisoning, which can potentially lead to accidental injuries, unsafe sex, suicide, sexual assault, and traffic accidents. The spread of these games through the internet and social networks is becoming a serious health problem facing physicians and medical professionals every day, especially in the ED; for this reason, it is necessary to be aware of the risks represented by such behaviors in order to recognize and identify preliminary symptoms and develop useful prevention programs. The strategic role of emergency services is to monitor and define the problem right from the start in order to control the epidemic, support planning, coordinate the delivery of assistance in the emergency phase, and provide medical education. Hospital-based interdisciplinary health care researchers collected specific data on hazardous drinking practices linked to evaluation of increased alcohol-related consequences and cases admitted to the ED.

Continuous wound infusion and local infiltration analgesia for postoperative pain and rehabilitation after total hip arthroplasty.

BACKGROUND: Total hip arthroplasty is one of the most common procedures in orthopedic surgery. We hypothesized that local infiltration of analgesia and continuous wound infusion of anesthetics in the first 72 hours after surgery could provide more effective postoperative analgesia with better rehabilitation. METHODS: A double-blind, randomized, controlled study was conducted with 96 patients who underwent total hip arthroplasty. The patients were randomized to receive either a local infiltration analgesia and continuous wound infusion of anesthetics or a local infiltration analgesia and continuous wound infusion of saline solution. The patients in both groups received subarachnoid anesthesia and a local infiltration analgesia. A multihole catheter was placed next to the implant and connected to an electronic pump containing a 300-mL solution of 0.2% levobupivacaine (experimental group) or saline (control group). RESULTS: A total of 96 consecutive patients were enrolled and randomized. Of these, 48 patients received local infiltration analgesia and continuous wound infusion of local anesthetics, and the remainder received local infiltration analgesia and continuous wound infusion of saline solution. The analysis showed a significant main effect of treatment on the postoperative incident of pain (Ftreat(1,93)=22.62, P=0.000) and on resting pain during the post-surgery follow-up (Ftreat(1,93)=15.62, P=0.0002). The pain scores during the rehabilitation period were significantly less in the experimental group. Analgesic consumption was less in the experimental group. CONCLUSIONS: The addition of continuous wound infusion of anesthetics to local infiltration analgesia provided an extended analgesic effect associated with good rehabilitation performance.

Perioperative coagulation assessment of patients undergoing major elective orthopedic surgery.

Traditional coagulative parameters are of limited use in identifying perioperative coagulopathy occurring in patients undergoing major elective orthopedic surgery (MEOS). The aim of our study was to evaluate the coagulation changes in patients undergoing MEOS and to facilitate an early detection of perioperative coagulopathy in patients experiencing major intraoperative bleeding. We enrolled 40 consecutive patients (M/F 10/30, age range 34-90 years) who underwent MEOS at the Orthopedic Unit of the Padua University Hospital, Italy, between January 2014 and January 2015. Blood samples were obtained at the following time points: T0-pre: 30 min before surgery; T0-post: 30 min after the end of the procedure; T1: morning of the first postoperative day; T2: 7 ± 2 days after surgery. Patients who experienced an intraoperative blood loss ≥250 mL/h were considered as cases. Routine coagulative parameters, thromboelastometry and thrombin generation (TG) profiles were evaluated. At baseline, a significantly lower platelet count and FIBTEM MCF/AUC were observed in patents with excessive bleeding (p < 0.05 and 0.02/0.01, respectively). At T0-post and T1 intervals, cases showed hypocoagulation characterized by a significantly low platelet count (p = 0.001), prolonged CFT INTEM/EXTEM, reduction of alpha-angle and MaxV INTEM/EXTEM, MCF and AUC INTEM/EXTEM/FIBTEM (p < 0.05 in all comparisons). The only TG parameter standing out between study groups was time to peak at T0-pre. A low platelet count and fibrinogen activity were associated with significant intraoperative bleeding in patients undergoing MEOS. Thromboelastometry performed by ROTEM(®) identifies patients with coagulopathy.

Unilateral paravertebral block compared with subarachnoid anesthesia for the management of postoperative pain syndrome after inguinal herniorrhaphy: a randomized controlled clinical trial.

Inguinal herniorrhaphy is a common surgical procedure. The aim of this investigation was to determine whether unilateral paravertebral block could provide better control of postoperative pain syndrome compared with unilateral subarachnoid block (SAB). A randomized controlled study was conducted using 50 patients with unilateral inguinal hernias. The patients were randomized to receive either paravertebral block (S group) or SAB (C group). Paravertebral block was performed by injecting a total of 20 mL of 0.5% levobupivacaine from T9 to T12 under ultrasound guidance, whereas SAB was performed by injecting 13 mg of 0.5% levobupivacaine at the L3 to L4 level. Data regarding anesthesia, hemodynamic changes, side effects, time spent in the postanesthesia care unit, the Karnofsky Performance Status, acute pain and neuropathic disturbances were recorded. Paravertebral block provided good anesthesia of the inguinal region without patient or surgeon discomfort, with better hemodynamic stability and safety and with a reduced time to discharge from the postanesthesia care unit compared with SAB. During the postsurgical and posthospital discharge follow-ups, rest and incident pain and neuropathic positive phenomena were better controlled in the S group than in the C group. The consumption of painkillers was higher in the C group than in the S group throughout the follow-up period. Paravertebral block can be considered a viable alternative to common anesthetic procedures performed for inguinal hernia repair surgery. Paravertebral block provided good management of acute postoperative pain and limited neuropathic postoperative disturbances.

A Review of Local Anesthetic Systemic Toxicity Cases Since Publication of the American Society of Regional Anesthesia Recommendations: To Whom It May Concern.

Local anesthetic systemic toxicity (LAST) occurrence may cross several medical specialties. In 2010, the American Society of Regional Anesthesia and Pain Medicine (ASRA) published the first algorithm on LAST management, introducing the use of lipid emulsion (ILE) treatment. In the present study, we retrieved the cases of LAST published between ASRA guidelines dissemination and March 2014. We analyzed the reported clinical manifestations of LAST, characteristics of affected patients, onset time of toxicity, and clinical setting. We also focused on the treatment measures that were applied in the different cases, especially on the use of ILE and adherence to ASRA recommendations. Despite the limits of a review of case reports, the present study calls attention to the insidious nature of LAST, especially its atypical manifestations, and shows that ILE may currently be underadministered in daily clinical practice, especially in nonanesthesiology practice.
