Global Perceptions on ERAS® in Pancreatoduodenectomy.

BACKGROUND: Uptake of ERAS® pathways for pancreatic surgery have been slow and impacted by low compliance. OBJECTIVE: To explore global awareness, perceptions and practice of ERAS® peri-pancreatoduodenectomy (PD). METHODS: A structured, web-based survey (EPSILON) was administered through the ERAS® society and IHPBA membership. RESULTS: The 140 respondents included predominantly males (86.4%), from Europe (45%), practicing surgery (95%) at academic/teaching hospitals (63.6%) over a period of 10-20 years (38.6%). Most respondents identified themselves as general surgeons (68.6%) with 40.7% reporting an annual PD volume of 20-50 cases, practicing post-PD clinical pathways (37.9%), with 31.4% of respondents auditing their outcomes annually. Reduced medical complications, cost and hospital length of stay, and improved patient satisfaction were perceived benefits of compliance to enhancing-recovery. Multidisciplinary co-ordination was considered the most important factor in the implementation and sustainability of peri-PD ERAS® pathways, while reluctance to change among health care practitioners, difficulties in data collection and audit, lack of administrative support, and recruitment of an ERAS® dedicated nurse were reported to be important barriers. CONCLUSIONS: The EPSILON survey highlighted global clinician perceptions regarding the benefits of compliance to peri-PD ERAS®, the importance of individual components, perceived facilitators and barriers, to the implementation and sustainability of these pathways.

Enhanced Recovery After Surgery and Elderly Patients: Advances.

Enhanced recovery after surgery (ERAS) is a new way of working where evidence-based care elements are assembled to form a care pathway involving the patient's entire journey through surgery. Many elements included in ERAS have stress-reducing effects on the body or helps avoid side effects associated with alternative treatment options. This leads to less overall stress from the injury caused by the operation and helps facilitate recovery. In old, frail patients with concomitant diseases and less physical reserves, this may help explain why the ERAS care is reported to be beneficial for this specific patient group.

Recurarization with magnesium sulfate administered after two minutes sugammadex reversal: A randomized, double-blind, controlled trial.

STUDY OBJECTIVE: The current study tested the hypothesis that magnesium sulfate after reversal with sugammadex causes recurarization. DESIGN: A single-center, prospective, randomized, double-blind, controlled trial. SETTING: Terciary care hospital in Rio de Janeiro, Brazil. PATIENTS: Included 60 patients undergoing for elective otolaryngological surgery. INTERVENTIONS: All patients received total intravenous anesthesia and a single dose of rocuronium (0.6 mg/kg). In 30 patients, the neuromuscular blockade was reversed with sugammadex (4 mg/kg) at the reappearance of one or two posttetanic counts (deep-blockade series). In 30 other patients, sugammadex (2 mg/kg) was administered at the reappearance of the second twitch of the train-of-four (moderate-blockade series). After the normalized train-of-four ratio recovered to ≥0.9, the patients in each series were randomized to receive intravenous magnesium sulfate (60 mg/kg) or placebo for 10 min. Neuromuscular function was measured by acceleromyography. MEASUREMENTS: The primary outcome was the number of patients who exhibited recurarization (normalized train-of-four ratio < 0.9). The secondary outcome was rescue with an additional dose of sugammadex after 60 min. MAIN RESULTS: In the deep-blockade series, a normalized train-of-four ratio < 0.9 occurred in 9/14 (64%) patients receiving magnesium sulfate and 1/14 (7%) receiving placebo, RR 9.0 (95% CI: 62-1.30), and (p = 0.002), with four rescues with sugammadex. In the moderate-blockade series, neuromuscular blockade recurred in 11/15 (73%) patients receiving magnesium sulfate and in 0/14 (0%) receiving placebo (p < 0.001), with two rescues. The absolute differences in recurarization were 57% and 73% in the deep-blockade and moderate-blockade, respectively. CONCLUSIONS: Single-dose magnesium sulfate led to a normalized train-of-four ratio < 0.9, 2 min after recovery from rocuronium-induced deep and moderate neuromuscular blockade using sugammadex. Additional sugammadex reversed prolonged recurarization.

A framework for perioperative care for lower extremity vascular bypasses: A Consensus Statement by the Enhanced Recovery after Surgery (ERAS®) Society and Society for Vascular Surgery.

The Society for Vascular Surgery and the Enhanced Recovery After Surgery (ERAS) Society formally collaborated and elected an international, multi-disciplinary panel of experts to review the literature and provide evidence-based suggestions for coordinated perioperative care for patients undergoing infrainguinal bypass surgery for peripheral artery disease. Structured around the ERAS core elements, 26 suggestions were made and organized into preadmission, preoperative, intraoperative, and postoperative sections.

Anaesthesia role in enhanced recovery after surgery: a revolution in care outcomes.

PURPOSE OF REVIEW: Enhanced recovery after surgery (ERAS) has revolutionized care outcomes. The purpose of this review is to provide an overview of how ERAS changed healthcare outcomes. RECENT FINDINGS: Development of multidisciplinary evidence-based ERAS guidelines for specific surgical specialties and systematic implementation of these guidelines resulted in improved healthcare outcomes, reduction in length of stay, reduction in complications and improved survival. The value of audit of the outcomes is essential for implementation and to improve healthcare. Healthcare economics analysis related to the implementation of ERAS showed significant cost savings up to a return to investment ratio of more than seven. SUMMARY: ERAS has revolutionized healthcare by developing evidence-based ERAS guidelines and systematic implementation of these guidelines. Audit of outcomes is essential, not only to improve healthcare but also to significantly save healthcare expenditures.

Peri-operative management of neuromuscular blockade: A guideline from the European Society of Anaesthesiology and Intensive Care.

Recent data indicated a high incidence of inappropriate management of neuromuscular block, with a high rate of residual paralysis and relaxant-associated postoperative complications. These data are alarming in that the available neuromuscular monitoring, as well as myorelaxants and their antagonists basically allow well tolerated management of neuromuscular blockade. In this first European Society of Anaesthesiology and Intensive Care (ESAIC) guideline on peri-operative management of neuromuscular block, we aim to present aggregated and evidence-based recommendations to assist clinicians provide best medical care and ensure patient safety. We identified three main clinical questions: Are myorelaxants necessary to facilitate tracheal intubation in adults? Does the intensity of neuromuscular blockade influence a patient's outcome in abdominal surgery? What are the strategies for the diagnosis and treatment of residual paralysis? On the basis of this, PICO (patient, intervention, comparator, outcome) questions were derived that guided a structured literature search. A stepwise approach was used to reduce the number of trials of the initial research ( n  = 24 000) to the finally relevant clinical studies ( n  = 88). GRADE methodology (Grading of Recommendations, Assessment, Development and Evaluation) was used for formulating the recommendations based on the findings of the included studies in conjunction with their methodological quality. A two-step Delphi process was used to determine the agreement of the panel members with the recommendations: R1 We recommend using a muscle relaxant to facilitate tracheal intubation (1A). R2 We recommend the use of muscle relaxants to reduce pharyngeal and/or laryngeal injury following endotracheal intubation (1C). R3 We recommend the use of a fast-acting muscle relaxant for rapid sequence induction intubation (RSII) such as succinylcholine 1 mg kg -1 or rocuronium 0.9 to 1.2 mg kg -1 (1B). R4 We recommend deepening neuromuscular blockade if surgical conditions need to be improved (1B). R5 There is insufficient evidence to recommend deep neuromuscular blockade in general to reduce postoperative pain or decrease the incidence of peri-operative complications. (2C). R6 We recommend the use of ulnar nerve stimulation and quantitative neuromuscular monitoring at the adductor pollicis muscle to exclude residual paralysis (1B). R7 We recommend using sugammadex to antagonise deep, moderate and shallow neuromuscular blockade induced by aminosteroidal agents (rocuronium, vecuronium) (1A). R8 We recommend advanced spontaneous recovery (i.e. TOF ratio >0.2) before starting neostigmine-based reversal and to continue quantitative monitoring of neuromuscular blockade until a TOF ratio of more than 0.9 has been attained. (1C).

Quality of Recovery and Innate Immune Homeostasis in Patients Undergoing Low-pressure Versus Standard-pressure Pneumoperitoneum During Laparoscopic Colorectal Surgery (RECOVER): A Randomized Controlled Trial.

OBJECTIVE: To study the effects of intra-abdominal pressure on the quality of recovery and innate cytokine production capacity after laparoscopic colorectal surgery within the enhanced recovery after surgery program. BACKGROUND: There is increasing evidence for the safety and advantages of low-pressure pneumoperitoneum facilitated by deep neuromuscular blockade (NMB). Nonetheless, there is a weak understanding of the relationship between clinical outcomes, surgical injury, postoperative immune dysfunction, and infectious complications. METHODS: Randomized controlled trial of 178 patients treated at standard-pressure pneumoperitoneum (12 mm Hg) with moderate NMB (train-of-four 1-2) or low pressure (8 mm Hg) facilitated by deep NMB (posttetanic count 1-2). The primary outcome was the quality of recovery (Quality of Recovery 40 questionnaire) on a postoperative day 1 (POD1). The primary outcome of the immune substudy (n=100) was ex vivo tumor necrosis factor α production capacity upon endotoxin stimulation on POD1. RESULTS: Quality of Recovery 40 score on POD1 was significantly higher at 167 versus 159 [mean difference (MD): 8.3 points; 95% confidence interval (CI): 2.5, 14.1; P =0.005] and the decline in cytokine production capacity was significantly less for tumor necrosis factor α and interleukin-6 (MD: -172 pg/mL; 95% CI: -316, -27; P =0.021 and MD: -1282 pg/mL; 95% CI: -2505, -59; P =0.040, respectively) for patients operated at low pressure. Low pressure was associated with reduced surgical site hypoxia and inflammation markers and circulating damage-associated molecular patterns, with a less impaired early postoperative ex vivo cytokine production capacity. At low pressure, patients reported lower acute pain scores and developed significantly less 30-day infectious complications. CONCLUSIONS: Low intra-abdominal pressure during laparoscopic colorectal surgery is safe, improves the postoperative quality of recovery and preserves innate immune homeostasis, and forms a valuable addition to future enhanced recovery after surgery programs.

Microcirculatory tissue perfusion during general anaesthesia and noncardiac surgery: An observational study using incident dark field imaging with automated video analysis.

BACKGROUND: Handheld vital microscopy allows direct observation of red blood cells within the sublingual microcirculation. Automated analysis allows quantifying microcirculatory tissue perfusion variables - including tissue red blood cell perfusion (tRBCp), a functional variable integrating microcirculatory convection and diffusion capacities. OBJECTIVE: We aimed to describe baseline microcirculatory tissue perfusion in patients presenting for elective noncardiac surgery and test that microcirculatory tissue perfusion is preserved during elective general anaesthesia for noncardiac surgery. DESIGN: Prospective observational study. SETTING: University Medical Center Hamburg-Eppendorf, Hamburg, Germany. PATIENTS: 120 elective noncardiac surgery patients (major abdominal, orthopaedic or trauma and minor urologic surgery) and 40 young healthy volunteers. MAIN OUTCOME MEASURES: We measured sublingual microcirculation using incident dark field imaging with automated analysis at baseline before induction of general anaesthesia, under general anaesthesia before surgical incision and every 30 min during surgery. We used incident the dark field imaging technology with a validated automated analysis software. RESULTS: A total of 3687 microcirculation video sequences were analysed. Microcirculatory tissue perfusion variables varied substantially between individuals - but ranges were similar between patients and volunteers. Under general anaesthesia before surgical incision, there were no important changes in tRBCp, functional capillary density and capillary haematocrit compared with preinduction baseline. However, total vessel density was higher and red blood cell velocity and the proportion of perfused vessels were lower under general anaesthesia. There were no important changes in any microcirculatory tissue perfusion variables during surgery. CONCLUSION: In patients presenting for elective noncardiac surgery, baseline microcirculatory tissue perfusion variables vary substantially between individuals - but ranges are similar to those in young healthy volunteers. Microcirculatory tissue perfusion is preserved during general anaesthesia and noncardiac surgery - when macrocirculatory haemodynamics are maintained.

Guidelines for Perioperative Care in Elective Abdominal and Pelvic Surgery at Primary and Secondary Hospitals in Low-Middle-Income Countries (LMIC's): Enhanced Recovery After Surgery (ERAS) Society Recommendation.

BACKGROUND: This is the first Enhanced Recovery After Surgery (ERAS®) Society guideline for primary and secondary hospitals in low-middle-income countries (LMIC's) for elective abdominal and gynecologic care. METHODS: The ERAS LMIC Guidelines group was established by the ERAS® Society in collaboration with different representatives of perioperative care from LMIC's. The group consisted of seven members from the ERAS® Society and eight members from LMIC's. An updated systematic literature search and evaluation of evidence from previous ERAS® guidelines was performed by the leading authors of the Colorectal (2018) and Gynecologic (2019) surgery guidelines (Gustafsson et al in World J Surg 43:6592-695, Nelson et al in Int J Gynecol Cancer 29(4):651-668). Meta-analyses randomized controlled trials (RCTs), prospective and retrospective cohort studies from both HIC's and LMIC's were considered for each perioperative item. The members in the LMIC group then applied the current evidence and adapted the recommendations for each intervention as well as identifying possible new items relevant to LMIC's. The Grading of Recommendations, Assessment, Development and Evaluation system (GRADE) methodology was used to determine the quality of the published evidence. The strength of the recommendations was based on importance of the problem, quality of evidence, balance between desirable and undesirable effects, acceptability to key stakeholders, cost of implementation and specifically the feasibility of implementing in LMIC's and determined through discussions and consensus. RESULTS: In addition to previously described ERAS® Society interventions, the following items were included, revised or discussed: the Surgical Safety Checklist (SSC), preoperative routine human immunodeficiency virus (HIV) testing in countries with a high prevalence of HIV/AIDS (CD4 and viral load for those patients that are HIV positive), delirium screening and prevention, COVID 19 screening, VTE prophylaxis, immuno-nutrition, prehabilitation, minimally invasive surgery (MIS) and a standardized postoperative monitoring guideline. CONCLUSIONS: These guidelines are seen as a starting point to address the urgent need to improve perioperative care and to effect data-driven, evidence-based care in LMIC's.

Perioperative care in open aortic vascular surgery: A consensus statement by the Enhanced Recovery After Surgery (ERAS) Society and Society for Vascular Surgery.

The Society for Vascular Surgery and the Enhanced Recovery After Surgery Society formally collaborated and elected an international, multidisciplinary panel of experts to review the literature and provide evidence-based recommendations related to all the health care received in the perioperative period for patients undergoing open abdominal aortic operations (both transabdominal and retroperitoneal approaches, including supraceliac, suprarenal, and infrarenal clamp sites) for aortic aneurysm and aortoiliac occlusive disease. Structured around the Enhanced Recovery After Surgery core elements, 36 recommendations were made and organized into preadmission, preoperative, intraoperative, and postoperative recommendations.

Opportunities and Challenges for the Next Phase of Enhanced Recovery After Surgery: A Review.

Importance: Enhanced Recovery After Surgery (ERAS) is a global surgical quality improvement initiative now firmly entrenched within the field of perioperative care. Although ERAS is associated with significant clinical outcome improvements and cost savings in numerous surgical specialties, several opportunities and challenges deserve further discussion. Observations: Uptake and implementation of ERAS Society guidelines, together with ERAS-related research, have increased exponentially since the inception of the ERAS movement. Opportunities to further improve patient outcomes include addressing frailty, optimizing nutrition, prehabilitation, correcting preoperative anemia, and improving uptake of ERAS worldwide, including in low- and middle-income countries. Challenges facing enhanced recovery today include implementation, carbohydrate loading, reversal of neuromuscular blockade, and bowel preparation. The COVID-19 pandemic poses both a challenge and an opportunity for ERAS. Conclusions and Relevance: To date, ERAS has achieved significant benefit for patients and health systems; however, improvements are still needed, particularly in the areas of patient optimization and systematic implementation. During this time of global crisis, the ERAS method of delivering care is required to take surgery and anesthesia to the next level and bring improvements in outcomes to both patients and health systems.

Consensus statement for perioperative care in lumbar spinal fusion: Enhanced Recovery After Surgery (ERAS®) Society recommendations.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) evidence-based protocols for perioperative care have led to improvements in outcomes in numerous surgical areas, through multimodal optimization of patient pathway, reduction of complications, improved patient experience and reduction in the length of stay. ERAS represent a relatively new paradigm in spine surgery. PURPOSE: This multidisciplinary consensus review summarizes the literature and proposes recommendations for the perioperative care of patients undergoing lumbar fusion surgery with an ERAS program. STUDY DESIGN: This is a review article. METHODS: Under the impetus of the ERAS® society, a multidisciplinary guideline development group was constituted by bringing together international experts involved in the practice of ERAS and spine surgery. This group identified 22 ERAS items for lumbar fusion. A systematic search in the English language was performed in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Systematic reviews, randomized controlled trials, and cohort studies were included, and the evidence was graded according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Consensus recommendation was reached by the group after a critical appraisal of the literature. RESULTS: Two hundred fifty-six articles were included to develop the consensus statements for 22 ERAS items; one ERAS item (prehabilitation) was excluded from the final summary due to very poor quality and conflicting evidence in lumbar spinal fusion. From these remaining 21 ERAS items, 28 recommendations were included. All recommendations on ERAS protocol items are based on the best available evidence. These included nine preoperative, eleven intraoperative, and six postoperative recommendations. They span topics from preoperative patient education and nutritional evaluation, intraoperative anesthetic and surgical techniques, and postoperative multimodal analgesic strategies. The level of evidence for the use of each recommendation is presented. CONCLUSION: Based on the best evidence available for each ERAS item within the multidisciplinary perioperative care pathways, the ERAS® Society presents this comprehensive consensus review for perioperative care in lumbar fusion.

The effect of low- versus normal-pressure pneumoperitoneum during laparoscopic colorectal surgery on the early quality of recovery with perioperative care according to the enhanced recovery principles (RECOVER): study protocol for a randomized controlled study.

BACKGROUND: There is increasing evidence for the use of lower insufflation pressures during laparoscopic surgery. Deep neuromuscular blockade allows for a safe reduction in intra-abdominal pressure without compromising the quality of the surgical field. While there is considerable evidence to support superior surgical conditions during deep neuromuscular blockade, there is only a limited amount of studies investigating patient outcomes. Moreover, results are not always consistent between studies and vary between different types of laparoscopic surgery. This study will investigate the effect of low-pressure pneumoperitoneum facilitated by deep NMB on quality of recovery after laparoscopic colorectal surgery. METHODS: The RECOVER study is a multicenter double-blinded randomized controlled trial consisting of 204 patients who will be randomized in a 1:1 fashion to group A, low-pressure pneumoperitoneum (8 mmHg) facilitated by deep neuromuscular blockade (post tetanic count of 1-2), or group B, normal-pressure pneumoperitoneum (12 mmHg) with moderate neuromuscular blockade (train-of-four response of 1-2). The primary outcome is quality of recovery on postoperative day 1, quantified by the Quality of Recovery-40 questionnaire. DISCUSSION: Few studies have investigated the effect of lower insufflation pressures facilitated by deep neuromuscular blockade on patient outcomes after laparoscopic colorectal procedures. This study will identify whether low pressure pneumoperitoneum and deep neuromuscular blockade will enhance recovery after colorectal laparoscopic surgery and, moreover, if this could be a valuable addition to the Enhanced Recovery After Surgery guidelines.

Recommendations for Managing Opioid-Tolerant Surgical Patients within Enhanced Recovery Pathways.

PURPOSE OF REVIEW: One of the consequences of the opioid epidemic is an increase in the number of opioid-tolerant patients. These patients are at higher risk for readmission and longer hospital stays following surgery. Enhanced recovery after surgery (ERAS) pathways can be used as a framework for providing high-quality comprehensive care to patient population. It is estimated that as many as 15% of all surgery patients in the USA are receiving opioids going into surgery. The number of patients on medication maintenance therapy with long-acting opioids such as methadone or partial mu receptor agonists like buprenorphine is rising, which poses a challenge for perioperative healthcare providers. RECENT FINDINGS: Preoperative opioid tolerance is an independent predictor for increased length of hospital stays, high costs, and increased readmission rates following surgery. Given the recent trends, it is likely that more opioid-tolerant patients will require surgery in near future. Enhanced recovery programs can be used to provide a framework for high-quality care to opioid-tolerant patients throughout all phases of the perioperative process. To improve the quality of care of opioid-tolerant patients, we present five general recommendations for clinicians to consider and possibly incorporate into ERAS programs and care protocols. Recommendations include the following: opioid-tolerant patients should not be excluded from ERAS programs; opioid-tolerant patients should be identified preoperatively; programs should establish standard practices for patients on medication maintenance therapy and buprenorphine; opioid-tolerant patients should receive multimodal analgesia perioperatively; and opioid-tolerant patients should receive coordinated follow up after surgery.

Effect of pretreatment with magnesium sulphate on the duration of intense and deep neuromuscular blockade with rocuronium: A randomised controlled trial.

BACKGROUND: Magnesium sulphate is an important adjuvant drug in multimodal anaesthesia. In combination with rocuronium it can enhance neuromuscular blockade (NMB). Limited data exist concerning the effect of magnesium sulphate on the duration of deep or intense NMB and the period of no response. OBJECTIVE(S): To determine the role of magnesium sulphate on the duration of rocuronium-induced deep and intense NMB, and the period of no response to nerve stimulation. DESIGN: A randomised controlled trial. SETTING: A public tertiary care hospital, Rio de Janeiro, Brazil, from February 2017 to March 2018. PATIENTS: All patients between 18 and 65 years of age scheduled to undergo elective otorhinolaryngological surgery, with a BMI between 18.5 and 24.9 kg m and an American Society of Anesthesiologists physical status classification of I or II. INTERVENTION(S): Before induction of anaesthesia 60 patients were pretreated with an intravenous infusion of either 100 ml 0.9% saline (saline group), or 60 mg kg magnesium sulphate (magnesium group). After loss of consciousness, a bolus of rocuronium (0.6 mg kg) was administered. Neuromuscular function was measured by TOF-Watch SX monitor. MAIN OUTCOME MEASURES: The primary and secondary outcomes were the duration of the period of no response to nerve stimulation and intense and deep NMB, respectively. An additional outcome was the NMB onset time. RESULTS: Median [IQR] durations of deep NMB were 20.3 [12.0 to 35.4] and 18.3 [11.2 to 26.3] min in the magnesium and saline groups, respectively (P = 0.18). Median durations of intense NMB were 21.7 [0.0 to 32.2] min and 0.0 [0.0 to 6.2] min (P = 0.001) in the magnesium and saline groups, respectively. Median durations of the period of no response were 40.8 [51.4 to 36.0] min and 28.0 [21.9 to 31.6] min (P = 0.0001) in the magnesium and saline groups, respectively. CONCLUSION: Magnesium sulphate increased both the duration of intense NMB and the period of no response. The duration of deep NMB was similar in the magnesium sulphate group and saline group.
