The last decade of the XXI century was marked by the active development and introduction into clinical practice of the technology of Enhanced recovery after surgery. It allows you to ensure a quick and high‑quality recovery after surgery, reduce the number of complications, reduce the time of hospitalization and medical costs without increasing repeated hospitalizations, postoperative morbidity and the need for observation in the intensive care unit, minimize differences in the provision of perioperative care in various medical institutions and improve the quality of medical care to the population.Aim. To describe the history of development and current state of Enhanced recovery after surgery (ERAS or fast‑track), to present the ERAS Society protocol for spine surgery in adults and a consolidated protocol in children, and also have determined the results of the implementation of ERAS in various sections of spinal neurosurgery.

Introduction. In recent years, Enhanced recovery after surgery (ERAS), or Fast-track, has been actively developed and introduced into clinical practice in many industry of surgery in Europe and the USA. However, the ERAS® Society has not yet approved a unified protocol in spinal neurosurgery, and most of the publications on the topic have appeared only in the last few years.The purpose of the study is to present a systematic review of the literature to identify the key elements of the ERAS program and the effect of their use, as well as the impact on complications in the following areas of spinal neurosurgery: deformities, trauma, degenerative, infectious and oncology diseases.Materials and methods. The authors analyzed and systematically reviewed all published literature on ERAS in spine and spinal cord surgery up to October 10, 2020 using the main databases of medical literature and search resources PubMed and eLibrary according to the PICOS inclusion and exclusion criteria, as well as the recommendations of the protocol for writing systematic reviews. and PRISMA meta-analyses.Results. We analyzed 13 articles considering the use of ERAS technology in surgery for deformities (n = 3), degenerative (n = 8) and tumor (n = 2) lesions of the spine. The level of evidence of the study is 2a. The publications contain information on the treatment of 2,777 patients, whose average age was 50.5 years (from 14.0 to 72.4 years). The ERAS protocol has been implemented in clinics in the USA (46 %), China (30 %), France (8 %), Russia (8 %) and Great Britain (8 %). The average number of key elements of the ERAS program was 13.7 (range 5 to 24). The most popular are: preoperative patient counseling and education, minimally invasive surgery, multimodal analgesia, early mobilization and enteral loading, as well as active follow-up and care. The introduction of the ERAS protocol in spinal surgery made it possible, compared with the control group, to reduce the duration of hospitalization by 1.8 days (from 0.17 to 3.2 days), the cost of treatment by $ 1,443.75 (from 146 to $ 3,444), the severity of pain syndrome and the use of opioids in 38 % of cases, the consumption of antiemetics after surgery, as well as the time of surgery and blood loss at 29 minutes and 188 ml, respectively. For ERAS-groups, cardiovascular and respiratory complications are more typical, and for control groups – urinary, infectious, thromboembolic complications and liquorrhea. In general, there is a decrease in the total number of complications by 8.5 % (from 2.3 to 9.6 %).Conclusions. Enhanced recovery after surgery is a promising technology for improving the quality of care for patients in spine surgery.

Objective. To analyze the attitude of neurosurgeons to the technology of enhanced recovery after spine and spinal cord surgery in the Russian Federation.Material and Methods. In March 2022, a continuous cohort comparative sociological study was conducted among 83 neurosurgeons of the Russian Federation, during which they were asked to fill out a specially designed online questionnaire consisting of 22 questions on the Google Forms platform.Results. The vast majority of respondents (95.2 %) noted the lack of information in the Russian literature on the technology of enhanced recovery after surgery (ERAS). Nevertheless, most neurosurgeons, regardless of specialization, are familiar with the terms “fast track” (79.5 %) and “ERAS” (60.2 %). Only 44.6 % of specialists declared the implementation of ERAS recommendations into their daily clinical practice, while 78.3 % of neurosurgeons draw attention to the existence of problems that hamper adoption of enhanced recovery protocols (ERP) in Russia. The interviewed respondents are confident that it is possible to introduce ERP into spinal neurosurgery in adults (91.6 %) and children (85.5 %) in Russia. Every second respondent (50.6 %) considers it possible to directly extrapolate foreign ERP into clinical practice in Russian healthcare. Spinal neurosurgeons are more aware of ERAS than cerebral neurosurgeons (p = 0.017), and they also more often use elements of ERAS in their clinical practice (p = 0.002). In other parameters, the respondents did not differ significantly depending on their specialization. Only 7.2 % of interviewed neurosurgeons work in private clinics. All of them are engaged in spinal surgery and introduce the ERAS technology into their clinical practice. Less than half (40.0 %) of neurosurgeons in public clinics implement elements of the ERAS (p = 0.007). More than half (69.7 %) of specialists and every second manager consider the introduction of ERAS in a neurosurgical clinic to be progressive, and only a few of them (3.6 %), on the contrary, believe that the quality of medical care may decrease with the introduction of ERAS. Neurosurgeons (n = 13) identified 7 clinics of the Russian Federation, where the enhanced recovery protocol after spine surgery is implemented. In total, according to the results of the study, 23 elements of the ERAS protocol are implemented in the practice of respondents (n = 20) in the conditions of Russian healthcare.Conclusions. Despite the lack of publications in the Russian literature and the existing organizational problems in the context of domestic healthcare, neurosurgeons have a positive attitude towards the introduction of ERAS protocol into clinical practice. This protocol or its individual elements are already successfully implemented in a group of clinics in Russia.

Objective. To conduct a systematic review of the literature on the use of enhanced recovery after surgery (ERAS) protocols in spinalsurgery of children and adolescents to determine the existing evidence of the effectiveness of ERAS implementation in clinical practice.Material and Methods. The authors conducted a systematic review of the literature on ERAS in spinal and spinal cord surgery in children and adolescents selected in the databases of medical literature and search resources of PUBMED/MEDLINE, Google Scholar, Cochrane Library and eLibrary according to the PRISMA guidelines and the PICOS inclusion and exclusion criteria.Results. A total of 12 publications containing information on the treatment of 2,145 children, whose average age was 14.0 years (from 7.2 to 16.1), were analyzed. In the reviewed publications, the average number of key elements of the ERAS program was 9 (from 2 to 20), and a total of 23 elements used in spinal surgery in children and adolescents were identified. The most commonly used elements were preoperative education and counseling, prevention of infectious complications and intestinal obstruction, multimodal analgesia, refusal of routine use of drains, nasogastric probes and urinary catheters, standardized anesthesia protocol, early mobilization and enteral loading. The introduction of the ERAS protocol into clinical practice allowed to reduce the complication rate in comparison with the control group by 8.2 %(from 2 to 19 %), the volume of blood loss by 230 ml (from 75 to 427 ml), the operation time by 83 minutes (from 23 to 144 minutes), theduration of hospitalization by 1.5 days (from 0.5 to 3 days) and the total cost of treatment by 2258.5 dollars (from 860 to 5280 dollars).The ERAS program was implemented in pediatric clinics in the USA (75 %), France (8 %) and Canada (17 %).Conclusion. The conducted systematic review of the literature allows us to conclude that the technology of enhanced recovery after surgery is a promising technology that improves surgical outcomes and is applicable in pediatric practice. There is a significant shortage of published studies evaluating the implementation of ERAS in pediatric surgical practice in general, and in spinal surgery in particular, which requires further prospective randomized studies to evaluate ERAS in spinal surgery in children and adolescents.
