Bajsová, S, Klát, J
Ceska gynekologie. 2019;(5):376-385
Abstract
OBJECTIVE To summarize current knowledge of the ERAS protocol in gynecologic oncology surgery. DESIGN Review article. SETTINGS Department of Obstetrics and Gynecology, University Hospital Ostrava, Ostrava, Department of Obstetrics and Gynecology, University of Ostrava, Ostrava. METHODS Literature review, PubMed and Medline databases were used to search relevant literature from 1995 to 2019. CONCLUSION ERAS (Enhanced Recovery after Surgery) is a perioperative treatment program based on evidence-based medicine. Guidelines consist of pre-operative, perioperative and post-operative care items. Implementation of the ERAS protocol leads to a decrease in complications up to 40% and a reduction in hospitalization by up to 30%, thereby reducing overall costs without increasing the number of rehospitalizations. Multidisciplinary cooperation not only with anesthesiologists and consultant surgeons, but also with nutritional specialists and nurses is crucial.

Perioperative considerations and anesthesia management in patients with obstructive sleep apnea undergoing ophthalmic surgery.
Cok, OY, Seet, E, Kumar, CM, Joshi, GP
Journal of cataract and refractive surgery. 2019;(7):1026-1031
Abstract
Obstructive sleep apnea (OSA) is a disorder characterized by breathing cessation caused by obstruction of the upper airway during sleep. It is associated with multiorgan comorbidities such as obesity, hypertension, heart failure, arrhythmias, diabetes mellitus, and stroke. Patients with OSA have an increased prevalence of ophthalmic disorders such as cataract, glaucoma, central serous retinopathy (detachment of retina, macular hole), eyelid laxity, keratoconus, and nonarteritic anterior ischemic optic neuropathy; and some might require surgery. Given that OSA is associated with a high incidence of perioperative complications and more than 80% of surgical patients with OSA are unrecognized, all surgical patients should be screened for OSA (eg, STOP-Bang questionnaire) with comorbidities identified. Patients suspected or diagnosed with OSA scheduled for ophthalmic surgery should have their comorbid conditions optimized. This article includes a review of the literature and highlights best perioperative anesthesia practices in the management of ophthalmic surgical patients with OSA.

Abstract
INTRODUCTION Geriatric patients have a pronounced risk to suffer from postoperative complications. While effective risk-specific perioperative measures have been studied in controlled experimental settings, they are rarely found in routine healthcare. This study aims (1) to implement a multicomponent preoperative and intraoperative intervention, and investigate its feasibility, and (2) exploratorily assess the effectiveness of the intervention in routine healthcare. METHODS AND ANALYSIS Feasibility and exploratory effectiveness of the intervention will be investigated in a monocentric, prospective, non-randomised, controlled trial. The intervention includes systematic information for patients and family about measures to prevent postoperative complications; preoperative screening for frailty, malnutrition, strength and mobility with nutrient supplementation and physical exercise (prehabilitation) as needed. Further components focus on potentially inadequate medication, patient blood-management and carbohydrate loading prior to surgery, retainment of orientation aids in the operating room and a geriatric anaesthesia concept. Data will successively be collected from control, implementation and intervention groups. Patients aged 65+ with impending surgery will be included. A sample size of 240, n=80 per group, is planned. Assessments will take place at inclusion and 2, 30 and 180 days after surgery. Mixed-methods analyses will be performed. Exploratory effectiveness will be assessed using mixed segmented regressions. The primary endpoint is functional status. Secondary endpoints include cognitive performance, health-related quality of life, length of inpatient stay and occurrence of postoperative complications. Feasibility will be assessed through semi-structured interviews with staff and patients and quantitative analyses of the data quality, focussing on practicability, acceptance, adoption and fidelity to protocol. ETHICS AND DISSEMINATION The study will be carried out in accordance with the Helsinki Declaration and to principles of good scientific practice. The Ethics Committee of the Medical Association Hamburg, Germany, approved the protocol (study ID: PV5596). Results will be disseminated in scientific journals and healthcare conferences. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Identifier: NCT03325413.

Journal of laparoendoscopic & advanced surgical techniques. Part A. 2019;(2):178-183
Abstract
OBJECTIVE To investigate the clinical application value of enhanced recovery after surgery (ERAS) combined with the laparoscopic technique in the radical resection of colorectal cancer. METHODS A total of 200 patients undergoing laparoscopic radical surgery for colorectal cancer from June 2014 to June 2017 were selected and randomly divided into ERAS group (n = 100) and conventional (CON) group (n = 100). The ERAS group adopted enhanced recovery approach after surgery for perioperative treatment, while the CON group adopted a CON approach. The operation time, blood loss, first exhaust time, first defecation time, extubation time, complication rate (incision infection, pneumonia, gastric retention, anastomotic leakage, intestinal obstruction, etc.), scores of visual analog scale (VAS) 1, 3, and 7 days after surgery, and nutritional status (albumin, total protein) 1, 3, and 7 days after surgery were compared and analyzed. RESULTS Compared with the CON group, the ERAS group had significantly shorter first exhaust time, first defecation time, and extubation time (all P < .05). The incidence of overall complications in the ERAS group was less than those in the CON group (P < .05); and albumin and total protein were significantly higher in the ERAS group than in the CON group (both P < .05). CONCLUSIONS ERAS combined with laparoscopic techniques for the treatment of colorectal cancer is a safe and feasible practice. It not only promoted the recovery of gastrointestinal function but also improved the perioperative nutritional status of patients.

Abstract
With increasing life expectancy and technological advancement, provision of anaesthesia for elderly patients has become a significant part of the overall case-load. These patients are unique, not only because they are older with more propensity for comorbidity but a decline in physiological reserve and cognitive function invariably accompanies ageing; this can substantially impact peri-operative outcome and quality of recovery. Furthermore, it is not only morbidity and mortality that matters; quality of life is also especially relevant in this vulnerable population. Comprehensive geriatric assessment is a patient-centred and multidisciplinary approach to peri-operative care. The assessment of frailty has a central role in the pre-operative evaluation of the elderly. Other essential domains include optimisation of nutritional status, assessment of baseline cognitive function and proper approach to patient counselling and the decision-making process. Anaesthetists should be proactive in multidisciplinary care to achieve better outcomes; they are integral to the process.

Abstract
INTRODUCTION Among the measures taken in the recent years to reduce the morbidity and improve functional recovery after radical cystectomy (RC), the optimization of perioperative care pathways is gaining a prominent role. The aim of this systematic review of the literature with meta-analysis is to assess the impact of enhanced recovery after surgery (ERAS) protocols vs. standard of care on perioperative outcomes of patients undergoing RC. EVIDENCE ACQUISITION A systematic review with meta-analysis was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. MEDLINE, SCOPUS and Web of Science databases were searched. Only comparative studies evaluating the impact of ERAS protocols vs. standard of care on intraoperative and postoperative outcomes of patients undergoing RC were included. Cumulative analysis was conducted using Review Manager v.5.3 software. Statistical heterogeneity was tested using the χ2 Test, and a P value <0.10 was used to indicate heterogeneity. Random-effects and fixed-effects models were used as appropriate depending on heterogeneity status. EVIDENCE SYNTHESIS A total of 27 studies were included, namely 3 randomized and 24 non-randomized controlled studies, resulting in 4712 patients, 2690 (57%) participants to some ERAS protocol and 2022 (43%) controls receiving standard of care. A number of primary and secondary outcome measures were assessed in the original studies. Pooled data showed that ERAS protocols were associated with significantly faster recovery of bowel function, faster return to regular diet and shorter hospital stay with no increase in 30-day and 90-day major complication, mortality or readmission rates compared to standard of care. The magnitude of benefit of the various ERAS protocols tested had, however, a non-negligible inter-study variability. CONCLUSIONS This systematic review with meta-analysis of comparative studies showed that ERAS protocols applied to patients undergoing RC enabled a faster recovery of bowel function, a faster return to regular diet and a shorter hospital stay with no increase in major complication or readmission rate compared to standard perioperative care. RC with ERAS protocols should be considered the new standard of care.

World journal of surgery. 2019;(2):299-330
Abstract
INTRODUCTION Enhanced recovery after surgery (ERAS) programs provide a format for multidisciplinary care and has been shown to predictably improve short term outcomes associated with surgical procedures. Esophagectomy has historically been associated with significant levels of morbidity and mortality and as a result routine application and audit of ERAS guidelines specifically designed for esophageal resection has significant potential to improve outcomes associated with this complex procedure. METHODS A team of international experts in the surgical management of esophageal cancer was assembled and the existing literature was identified and reviewed prior to the production of the guidelines. Well established procedure specific components of ERAS were reviewed and updated with changes relevant to esophagectomy. Procedure specific, operative and technical sections were produced utilizing the best current level of evidence. All sections were rated regarding the level of evidence and overall recommendation according to the evaluation (GRADE) system. RESULTS Thirty-nine sections were ultimately produced and assessed for quality of evidence and recommendations. Some sections were completely new to ERAS programs due to the fact that esophagectomy is the first guideline with a thoracic component to the procedure. CONCLUSIONS The current ERAS society guidelines should be reviewed and applied in all centers looking to improve outcomes and quality associated with esophageal resection.

Balanced Crystalloids Versus Saline for Perioperative Intravenous Fluid Administration in Children Undergoing Neurosurgery: A Randomized Clinical Trial.
Lima, MF, Neville, IS, Cavalheiro, S, Bourguignon, DC, Pelosi, P, Malbouisson, LMS
Journal of neurosurgical anesthesiology. 2019;(1):30-35
Abstract
BACKGROUND Balanced crystalloid solutions induce less hyperchloremia than normal saline, but their role as primary fluid replacement for children undergoing surgery is unestablished. We hypothesized that balanced crystalloids induce less chloride and metabolic derangements than 0.9% saline solutions in children undergoing brain tumor resection. METHODS In total, 53 patients (age range, 6 mo to 12 y) were randomized to receive balanced crystalloid (balanced group) or 0.9% saline solution (saline group) during and after (for 24 h) brain tumor resection. Serum electrolyte and arterial blood gas analyses were performed at the beginning of surgery (baseline), after surgery, and at postoperative day 1. The primary trial outcome was the absolute difference in serum chloride concentrations (post-preopΔCl) measured after surgery and at baseline. Secondary outcomes included the post-preopΔ of other electrolytes and base excess (BE); hyperchloremic acidosis incidence; and the brain relaxation score, a 4-point scale evaluated by the surgeon for assessing brain edema. RESULTS Saline infusion increased post-preopΔCl (6 [3.5; 8.5] mmol/L) compared with balanced crystalloid (0 [-1.0; 3.0] mmol/L; P<0.001). Saline use also resulted in increased post-preopΔBE (-4.4 [-5.0; -2.3] vs. -0.4 [-2.7; 1.3] mmol/L; P<0.001) and hyperchloremic acidosis incidence (6/25 [24%] vs. 0; P=0.022) compared with balanced crystalloid. Brain relaxation score was comparable between groups. CONCLUSIONS In children undergoing brain tumor resection, saline infusion increased variation in serum chloride compared with balanced crystalloid. These findings support the use of balanced crystalloid solutions in children undergoing brain tumor resection.

Abstract
BACKGROUND Randomized controlled trials (RCTs) have yielded conflicting results regarding the ability of beta-blockers to influence perioperative cardiovascular morbidity and mortality. Thus routine prescription of these drugs in unselected patients remains a controversial issue. A previous version of this review assessing the effectiveness of perioperative beta-blockers in cardiac and non-cardiac surgery was last published in 2018. The previous review has now been split into two reviews according to type of surgery. This is an update and assesses the evidence in cardiac surgery only. OBJECTIVES To assess the effectiveness of perioperatively administered beta-blockers for the prevention of surgery-related mortality and morbidity in adults undergoing cardiac surgery. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, Biosis Previews and Conference Proceedings Citation Index-Science on 28 June 2019. We searched clinical trials registers and grey literature, and conducted backward- and forward-citation searching of relevant articles. SELECTION CRITERIA We included RCTs and quasi-randomized studies comparing beta-blockers with a control (placebo or standard care) administered during the perioperative period to adults undergoing cardiac surgery. We excluded studies in which all participants in the standard care control group were given a pharmacological agent that was not given to participants in the intervention group, studies in which all participants in the control group were given a beta-blocker, and studies in which beta-blockers were given with an additional agent (e.g. magnesium). We excluded studies that did not measure or report review outcomes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion, extracted data, and assessed risks of bias. We assessed the certainty of evidence with GRADE. MAIN RESULTS We included 63 studies with 7768 participants; six studies were quasi-randomized and the remaining were RCTs. All participants were undergoing cardiac surgery, and in most studies, at least some of the participants were previously taking beta-blockers. Types of beta-blockers were: propranolol, metoprolol, sotalol, esmolol, landiolol, acebutolol, timolol, carvedilol, nadolol, and atenolol. In twelve studies, beta-blockers were titrated according to heart rate or blood pressure. Duration of administration varied between studies, as did the time at which drugs were administered; in nine studies this was before surgery, in 20 studies during surgery, and in the remaining studies beta-blockers were started postoperatively. Overall, we found that most studies did not report sufficient details for us to adequately assess risk of bias. In particular, few studies reported methods used to randomize participants to groups. In some studies, participants in the control group were given beta-blockers as rescue therapy during the study period, and all studies in which the control was standard care were at high risk of performance bias because of the open-label study design. No studies were prospectively registered with clinical trials registers, which limited the assessment of reporting bias. We judged 68% studies to be at high risk of bias in at least one domain.Study authors reported few deaths (7 per 1000 in both the intervention and control groups), and we found low-certainty evidence that beta-blockers may make little or no difference to all-cause mortality at 30 days (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.47 to 1.90; 29 studies, 4099 participants). For myocardial infarctions, we found no evidence of a difference in events (RR 1.05, 95% CI 0.72 to 1.52; 25 studies, 3946 participants; low-certainty evidence). Few study authors reported cerebrovascular events, and the evidence was uncertain (RR 1.37, 95% CI 0.51 to 3.67; 5 studies, 1471 participants; very low-certainty evidence). Based on a control risk of 54 per 1000, we found low-certainty evidence that beta-blockers may reduce episodes of ventricular arrhythmias by 32 episodes per 1000 (RR 0.40, 95% CI 0.25 to 0.63; 12 studies, 2296 participants). For atrial fibrillation or flutter, there may be 163 fewer incidences with beta-blockers, based on a control risk of 327 incidences per 1000 (RR 0.50, 95% CI 0.42 to 0.59; 40 studies, 5650 participants; low-certainty evidence). However, the evidence for bradycardia and hypotension was less certain. We found that beta-blockers may make little or no difference to bradycardia (RR 1.63, 95% CI 0.92 to 2.91; 12 studies, 1640 participants; low-certainty evidence), or hypotension (RR 1.84, 95% CI 0.89 to 3.80; 10 studies, 1538 participants; low-certainty evidence).We used GRADE to downgrade the certainty of evidence. Owing to studies at high risk of bias in at least one domain, we downgraded each outcome for study limitations. Based on effect size calculations in the previous review, we found an insufficient number of participants in all outcomes (except atrial fibrillation) and, for some outcomes, we noted a wide confidence interval; therefore, we also downgraded outcomes owing to imprecision. The evidence for atrial fibrillation and length of hospital stay had a moderate level of statistical heterogeneity which we could not explain, and we, therefore, downgraded these outcomes for inconsistency. AUTHORS' CONCLUSIONS We found no evidence of a difference in early all-cause mortality, myocardial infarction, cerebrovascular events, hypotension and bradycardia. However, there may be a reduction in atrial fibrillation and ventricular arrhythmias when beta-blockers are used. A larger sample size is likely to increase the certainty of this evidence. Four studies awaiting classification may alter the conclusions of this review.
