Abstract Background Hepatocellular carcinoma (HCC) patients often undergo curative liver resection to treat this form of cancer. Hepatectomy is, however, a form of major surgery associated with many significant risks including prolonged hospitalization, high costs, impaired physiological function, and high postoperative complication rates. Enhanced recovery after surgery (ERAS) is a multidisciplinary approach that seeks to expedite postoperative recovery in patients undergoing major surgeries in order to lower postoperative complication rates. This study was thus designed to assess the efficacy and safety of individualized ERAS approaches in patients undergoing hepatectomy.  Methods In total, we retrospectively analyzed data from 90 HCC patients that underwent hepatectomy between October 2018 and August 2019. All patients met the study enrollment criteria and provided written informed consent to participate. All studies were approved by the Hospital Research Ethics Committee and were consistent with the Declaration of Helsinki. Patients were randomly divided into two groups (n = 45 each) based on the employed perioperative treatment strategies: a conventional treatment group and an ERAS treatment group. Key outcomes were then compared between groups, including postoperative pain scores, duration of postoperative hospitalization, medical costs, and rates of readmission.  Results ERAS treatment was associated with lower postoperative pain scores at 24, 48, and 72 h post-treatment (P < 0.05), with a shorter postoperative hospitalization duration (8.16 days vs.10.49 days; P < 0.004), and with lower medical costs (P < 0.004) as compared to traditional treatment. No significant differences in complication rates (P > 0.05) or readmission rates (P > 0.557) were observed between these groups.  Conclusions Individualized ERAS improves patient postoperative recovery more effectively than traditional treatment in patients undergoing hepatectomy.

Abstract Background: Enhanced recovery after surgery (ERAS) program is an evidence-based improvement over none-ERAS traditional care. The aim of the present study was to analyze the safety, feasibility, and efficacy of an ERAS program in patients over 70 years undergoing lumbar arthrodesis by comparison with none-ERAS traditional care.Methods: During January 2018 to December 2018, patients enrolled received none-ERAS traditional care, while the ERAS program was implemented from January to December 2019. Demographic characteristics, comorbidities, surgical data and postoperative recovery parameters were collected from all patients. Postoperative pain scores were evaluated by visual analog scales (VAS). The clinical outcomes were length of stay (LOS), postoperative complications and postoperative pain scores. Compliance results were also collected.Result: A total of 127 patients were enrolled, including 67 patients in the none-ERAS traditional care group and 60 patients in the ERAS group. The demographic characteristics and comorbidities of the two groups showed no significant differences. The LOS of patients treated with ERAS program (13.6±4.0 days) was significantly less than that of patients treated with none-ERAS traditional care (15.6±3.9 days) (p = 0.034). Complication rate was 8.3% in the ERAS group versus 20.9% in the none-ERAS traditional care group (p = 0.048). VAS (back) in the ERAS group was significantly lower on postoperative day (POD) 1 and POD2. Postoperative recovery parameters were improved in the ERAS group. The overall compliance with the ERAS program was 94%.Conclusions: Based on our results, ERAS program is safer and more effective for elderly patients over 70 undergoing lumbar arthrodesis than none-ERAS traditional care.

Enhanced recovery after surgery (ERAS) are specially designed multimodal perioperative care pathways which are intended to attain and improve rapid recovery after surgical interventions by supporting preoperative organ function and attenuating the stress response caused by surgical trauma, allowing patients to get back to normal activities as soon as possible. Evidence-based protocols are prepared and published to implement the conception of ERAS. Although they vary amongst health care institutions, the main three elements (preoperative, perioperative, and postoperative components) remain the cornerstones. Postoperative pain influences the quality and length of the postoperative recovery period, and later, the quality of life. Therefore, the optimal postoperative pain management (PPM) applying multimodal analgesia (MA) is one of the most important components of ERAS. The main purpose of this article is to discuss the concept of MA in PPM, particularly reviewing the use of opioid-sparing measures such as paracetamol, nonsteroid anti-inflammatory drugs (NSAIDs), other adjuvants, and regional techniques.

OBJECTIVEEnhanced recovery after surgery (ERAS) and multimodal analgesia are established care models that minimize perioperative opioid consumption and promote positive outcomes after spine surgery. Opioid-free anesthesia (OFA) is an emerging technique that may achieve similar goals. The purpose of this study was to evaluate an OFA regimen within an ERAS pathway for lumbar decompressive surgery and to compare perioperative opioid requirements in a matched cohort of patients managed with traditional opioid-containing anesthesia (OCA).METHODSThe authors performed a retrospective analysis of prospectively collected data. They included 36 patients who underwent lumbar decompression under their ERAS pathway for spinal decompression between February and August 2018. Eighteen patients who received OFA were matched in a 1:1 ratio to a cohort managed with a traditional OCA regimen. The primary outcome was total perioperative opioid consumption. Postoperative pain scores (measured using the numerical rating scale [NRS]), opioid consumption (total morphine equivalents), and length of stay (time to readiness for discharge) were compared in the postanesthesia care unit (PACU). The authors also assessed compliance with ERAS process measures and compared compliance during 3 phases of care: pre-, intra-, and postoperative.RESULTSThere was a significant reduction in total perioperative opioid consumption in patients who received OFA (2.43 ± 0.86 oral morphine equivalents [OMEs]; mean ± SEM), compared to patients who received OCA (38.125 ± 6.11 OMEs). There were no significant differences in worst postoperative pain scores (NRS scores 2.55 ± 0.70 vs 2.58 ± 0.73) or opioid consumption (5.28 ± 1.7 vs 4.86 ± 1.5 OMEs) in the PACU between OFA and OCA groups, respectively. There was a clinically significant decrease in time to readiness for discharge from the PACU associated with OFA (37 minutes), although this was not statistically significantly different. The authors found high overall compliance with ERAS process measures (91.4%) but variation in compliance according to phase of care. The highest compliance occurred during the preoperative phase (94.71% ± 2.88%), and the lowest compliance occurred during the postoperative phase of care (85.4% ± 5.7%).CONCLUSIONSOFA within an ERAS pathway for lumbar spinal decompression represents an opportunity to minimize perioperative opioid exposure without adversely affecting pain control or recovery. This study reveals opportunities for patient and provider education to reinforce ERAS and highlights the postoperative phase of care as a time when resources should be focused to increase ERAS adherence.

Eras Protocol

ObjectiveEnhanced Recovery After Surgery (ERAS) protocols are designed to mitigate the physiologic stress response created by surgery, to decrease the time to resumption of daily activities, and to improve overall recovery. This study aims to investigate postoperative recovery outcomes following gynecologic surgery before and after implementation of an ERAS protocol.MethodsA retrospective chart review was performed of patients undergoing elective laparotomy at a major academic center following implementation of an ERAS protocol (11/4/2014–7/27/2016) with comparison to a historical cohort (6/23/2013–9/30/2014). The primary outcome was length of hospital stay. Secondary outcomes included surgical variables, time to recovery of baseline function, opioid usage, pain scores, and complication rates. Statistical analyses were performed using Wilcoxon rank sum, Fisher’s exact, and chi squared tests.ResultsOne hundred and thirty-three women on the ERAS protocol who underwent elective laparotomy were compared with 121 historical controls. There was no difference in length of stay between cohorts (median 4 days; P = 0.71). ERAS participants had lower intraoperative (45 vs 75 oral morphine equivalents; P < 0.0001) and postoperative (45 vs 154 oral morphine equivalents; P < 0.0001) opioid use. ERAS patients reported lower maximum pain scores in the post-anesthesia care unit (three vs six; P < 0.0001) and on postoperative day 1 (four vs six; P = 0.002). There was no statistically significant difference in complication or readmission rates.ConclusionsERAS protocol implementation was associated with decreased intraoperative and postoperative opioid use and improved pain scores without significant changes in length of stay or complication rates.

Objective To investigate the impact of enhanced recovery after surgery (ERAS) on the postoperative neutrophil–lymphocyte ratio (NLR) in patients with colorectal cancer. Methods A total of 200 patients with colorectal cancer who underwent surgery between January 2015 and November 2018 were enrolled in the study. They were divided into a traditional treatment group (n=100) and an ERAS group (n=100). The traditional treatment group underwent radical laparoscopic colorectal surgery, and the ERAS group underwent traditional treatment plus the ERAS protocol (preoperative improvement of glucose tolerance, unconventional indwelling stomach and urinary tubes, intraoperative body temperature management, fluid management, postoperative pain management, early oral feeding, and early activities). Clinical data were collected for all patients. NLR levels before and after surgery, and complications were compared between the two groups. Results Postoperative NLR was significantly lower in the ERAS compared with the traditional treatment group. The incidence of complications, including anastomotic leakage, pulmonary infection, urinary tract infection, and cardiopulmonary dysfunction were also significantly lower in the ERAS group. Conclusion Enhanced recovery after surgery can reduce the increase in postoperative NLR and reduce the occurrence of postoperative complications, which results will be of clinical value.

Abstract Background Opioids are a mainstay of pain management. To limit the use of opioids, enhanced recovery after surgery (ERAS) protocols implement multimodal approaches to treat postoperative pain. Objective This paper aims to be the first to assess the efficacy of an ERAS protocol inclusive of ultrasound-guided, surgeon-led regional blocks for outpatient plastic surgery patients. Methods A retrospective review of patients undergoing outpatient plastic surgery on an ERAS protocol was performed. These patients were compared to a well-matched group not on an ERAS protocol (pre-ERAS). Endpoints included the amounts of opioid, anti-nausea, and antispasmodic medication prescribed. ERAS patients were given a postoperative questionnaire to assess both pain levels (0-10) and opioid consumption. ERAS patients anticipated to have higher levels of pain had ultrasound-guided anesthetic blocks. Results There were 157 patients in the pre-ERAS group and 202 patients in the ERAS group. Patients in the pre-ERAS group were prescribed more opioids (332.3 vs. 100.3 morphine milligram equivalents (MME)/patient; p &lt; 0.001), anti-nausea (664 vs. 16.3mg of promethazine/patient; p &lt; 0.001), and antispasmodic (401.3 vs. 31.2mg of cyclobenzaprine/patient; p &lt; 0.001) medication. Patients on the ERAS protocol consumed an average total of 22.7 MME/patient post-operatively. Average pain scores in this group peaked at 5.32 on POD1 and then decreased significantly daily. Conclusions Implementation of an ERAS protocol for outpatient plastic surgery patients with utilization of ultrasound-guided regional anesthetic blocks is feasible and efficacious. The ability to significantly decrease prescribed opioids in this unique patient population is noteworthy.

Abstract Background To investigate the effects of enhanced recovery after surgery (ERAS) in patients undergoing gynecologic surgery on length of hospital stay, pain management, and complication rate. Results The length of hospital stay was reduced in ERAS groups when compared with the control groups (3.46 days vs 2.28 days; P < 0.0001; CI − 1.5767 to − 0.7833 for laparotomy groups and 2.18 vs 1.76 days; P = 0.0115; CI − 0.7439 to − 0.0961 for laparoscopy groups respectively). Intraoperative fluid use was reduced in both ERAS groups compared to the two control groups (934 ± 245 ml and 832 ± 197 ml vs 1747 ± 257 ml and 1459 ± 304 respectively; P < 0.0001) and postoperative fluid use was also less in the ERAS groups compared to the control groups (1606 ± 607 ml and 1210 ± 324 ml vs 2682 ± 396 ml and 1469 ± 315 ml respectively; P < 0.0001). Pain score using visual analog scale (VAS) on postoperative day 0 was 4.8 ± 1.4 and 4.1 ± 1.2 (P = 0.0066) for both laparotomy control and ERAS groups respectively, while in the laparoscopy groups, VAS was 3.8 ± 1.1 and 3.2 ± 0.9 (P = 0.0024) in control and ERAS groups respectively. Conclusion Implementation of ERAS protocols in gynecologic surgery was associated with significant reduction in length of hospital stay, associated with decrease intravenous fluids used and comparable pain control without increase in complication rates.

Abstract Background Enhanced Recovery After Surgery (ERAS) is a multimodal perioperative care bundle aimed at the early recovery of patients. Well accepted in gastric and pelvic surgeries, there is minimal evidence in neurosurgery and neurocritical care barring spinal surgeries. We wished to compare the length of intensive care unit (ICU) or high dependency unit (HDU) stay of patients undergoing elective craniotomy for supratentorial neurosurgery: ERAS protocol versus routine care. The secondary objective was to compare the postoperative pain scores, opioid use, glycemic control, and the duration of postoperative hospital stay between the two groups. Methods In this pragmatic non-randomized controlled trial (CTRI/2017/07/015451), consenting adult patients scheduled for elective supratentorial intracranial tumor excision were enrolled prospectively after institutional ethical clearance and consent. Elements-of-care in the ERAS group were- Preoperative –family education, complex-carbohydrate drink, flupiritine; Intraoperative – scalp blocks, limited opioids, rigorous fluid and temperature regulation; Postoperative- flupiritine, early mobilization, removal of catheters, and initiation of feeds. Apart from these, all perioperative protocols and management strategies were similar between groups. The two groups were compared with regards to the length of ICU stay, pain scores in ICU, opioid requirement, glycemic control, and hospital stay duration. The decision for discharge from ICU and hospital, data collection, and analysis was by independent assessors blind to the patient group. Results Seventy patients were enrolled. Baseline demographics – age, sex, tumor volume, and comorbidities were comparable between the groups. The proportion of patients staying in the ICU for less than 48 h after surgery, the cumulative insulin requirement, and the episodes of VAS scores > 4 in the first 48 h after surgery was significantly less in the ERAS group – 40.6% vs. 65.7%, 0.6 (±2.5) units vs. 3.6 (±8.1) units, and one vs. ten episodes (p = 0.04, 0.001, 0.004 respectively). The total hospital stay was similar in both groups. Conclusion The study demonstrated a significant reduction in the proportion of patients requiring ICU/ HDU stay > 48 h. Better pain and glycemic control in the postoperative period may have contributed to a decreased stay. More extensive randomized studies may be designed to confirm these results.

Abstract Purpose Effectiveness of sufentanil sublingual tablet system (SSTS) compared to oral oxycodone in the management of postoperative pain after total knee arthroplasty (TKA) within an enhanced recovery after surgery (ERAS) protocol. Methods This pragmatic, parallel, open label, randomized controlled, trial enrolled 72 adult patients scheduled for TKA under spinal anesthesia following ERAS pathway. In addition to multimodal analgesia, patients received SSTS 15 mcg (SSTS group) or oral oxycodone extended release 10 mg twice daily and oral oxycodone immediate-release 5 mg up to four times daily on demand (Oxy group) to control pain during 48 h postoperatively. The primary endpoint was pain measured using a numeric rating scale at 24 h postoperatively. Time to first mobilization, side effects and patient satisfaction were also recorded. Results Median pain score at 24 h at rest was 3 [2–4] for Oxy group vs 2 [1.75–3] for SSTS group (p = 0.272) whereas median pain score on movement was 4 [3–6] vs 3 [2–5] respectively (p = 0.059). No difference in time to first mobilization was found between the two groups. The method of pain control was judged good/excellent for 83.9% of patients in the SSTS group compared with 52.9% in the Oxy group (p = 0.007). The incidence of nausea was 33% in SSTS group and 9% in Oxy group (p = 0.181). Conclusions In complement to ERAS multimodal analgesia, sublingual sufentanil 15 mcg tablet system did not show clinically significant pain improvement compared to oral oxycodone after total knee arthroplasty.
