A retrospective review of effectiveness of ERAS post-operative pain protocol in hip replacement surgeries under general anaesthesia at a tertiary orthopaedic hospital

: The concept of enhanced recovery after surgery (ERAS) was first introduced in 1997 by a group of European surgeons led by Henrik Kehlet. The ERAS concept was introduced to target the factors delaying post-operative recovery such as organ dysfunction, surgical stress and to improve the surgical outcomes and length of stay at the hospital. The primary aim of this approach is to reduce the body’s response to surgical stress by implementing a multidisciplinary, multitude of interventions in a coordinated clinical pathway. It was first implemented for colorectal surgeries to improve the post-surgical recovery rates by decreasing the post-operative ileus and thereby reducing the cost and length of hospital stay. Since the successful introduction of the program, ERAS has been used in several other specialties such as breast, urological, gynaecological, and musculoskeletal procedures. Off-late ERAS has become important in orthopaedic surgeries, particularly elective hip and knee arthroplasties. A retrospective review audit was conducted at tertiary Orthopaedic NHS Hospital to determine the effectiveness of ERAS post-operative pain protocol in patients who had primary hip arthroplasty under general anaesthesia. The qualitative and quantitative data included the length of stay at the hospital and default rates in the ERAS pain protocol. The length of stay at the hospital in ERAS compliant group was a mean of 3.95 days and in ERAS default group was 4.7 days, showing an increase of 16% in the total duration. The IV PCA group had 4.6 days of the average length of stay.: ERAS pathway advocates for using opioid-sparing multimodal analgesia to control pain, peripheral nerve blocks (single-shot/continuous), and local infiltration /peri-articular injections have become a better alternative to opioids in controlling the immediate post-surgical pain effectively. There is clear evidence to suggest that these techniques can improve patient outcomes and decrease the duration of stay.

Effects of perioperative clinical hypnosis on heart rate variability in patients undergoing oncologic surgery: secondary outcomes of a randomized controlled trial.

Clinical hypnosis has been proposed for post-surgical pain management for its potential vagal-mediated anti-inflammatory properties. Evidence is needed to understand its effectiveness for post-surgical recovery. Iin this secondary outcome study, it was hypothesized that surgical oncology patients randomized to receive perioperative clinical hypnosis (CH) would demonstrate greater heart-rate variability (HRV) during rest and relaxation at a 1-month post-surgery assessment compared to a treatment-as-usual group (TAU). After REB approval, trial registration and informed consent, 92 participants were randomized to receive CH (n = 45) or TAU (n = 47). CH participants received a CH session before surgery and during post-surgical in-hospital stay HRV was assessed during rest (5 min) and relaxation (10 min) before and 1-month after surgery. Pain intensity was obtained using a 0-10 numeric rating scale pre and post 1-week and 1-month post surgery. One month after surgery, HRV was significantly higher in CH group (n = 29) during rest and relaxation (both p < 0.05, d = 0.73) than TAU group (n = 28). By contrast, rest and relaxation HRV decreased from pre- to 1-month post-surgery for the TAU (both p < 0.001, d > 0.48) but not the CH group. Pain intensity increased from pre-surgery to 1-week post-surgery (p < 0.001, d = 0.50), and decreased from 1-week to 1-month post-surgery (p = 0.005, d = 0.21) for all participants. The results suggest that hypnosis prevents the deleterious effects of surgery on HRV by preserving pre-operative vagal activity. These findings underscore the potential of clinical hypnosis in mitigating the adverse effects of surgery on autonomic function and may have significant implications for enhancing post-surgical recovery and pain management strategies.

Biodegradable nanofiber coated human umbilical cord as nerve scaffold for sciatic nerve regeneration in albino Wistar rats.

Human umbilical cord (hUC) is encompassed by a mucoid connective tissue called Wharton's jelly (WJ), made of hyaluronic acid, collagen, and stromal cells to support the blood vessels of hUC. This study was aimed to determine the in vitro neuronal differentiation of WJ-derived mesenchymal stem cells (WJMSCs), and in vivo axonal regeneration potential of nanofiber coated human Wharton's jelly as a neuronal graft after sciatic nerve injury in immunosuppressed albino Wistar rats. Wharton's jelly-derived mesenchymal stem cells could be differentiated to neuron-like cells by inducing with neuronic supplementing media. The test animal's axotomized nerves were implanted with trimmed human umbilical cord devoid of vascularity and nanocoated with electro-spun poly-l-lactic acid nanofibers. The control animals were bridged with native sciatic nerve reversed and sutured. Post-surgical functional recovery was studied by walking track, pinprick, muscle weight, and sweating quantification. At the end of the 4th week, the animals were euthanized, and magnetoneurography was performed. The explanted grafts were quantified by immunohistochemistry for immuno-rejection, neural scarring, neural adhesion axon regeneration, fibre diameter, myelin thickness, and G-ratio. The sciatic function index values were similar by walking track analysis for both the test and control groups. The animals had functional and sensation recovery by the end of 2 weeks. No mortality, signs of inflammation, and acute immune rejection were observed post-surgery. The hUCWJ devoid of vascular elements can be a perfect peripheral nerve graft, and we hypothesis that the cryopreserved hUC could be an ideal resource for axonal regeneration in the future.

Enhanced recovery after surgery from 1997 to 2022: a bibliometric and visual analysis.

Enhanced recovery after surgery (ERAS) is a multimodal perioperative management concept, but there is no article to comprehensively review the collaboration and impact of countries, institutions, authors, journals, references, and keywords on ERAS from a bibliometric perspective. This study assessed the evolution of clustering of knowledge structures and identified hot trends and emerging topics. Articles and reviews related to ERAS were retrieved through subject search from the Web of Science Core Collection. We used the following strategy: "TS = Enhanced recovery after surgery" OR "Enhanced Postsurgical Recovery" OR "Postsurgical Recoveries, Enhanced" OR "Postsurgical Recovery, Enhanced" OR "Recovery, Enhanced Postsurgical" OR "Fast track surgery" OR "improve surgical outcome". Bibliometric analyses were conducted on Excel 365, CiteSpace, VOSviewer, and Bibliometrics (R-Tool of R-Studio). Totally 3242 articles and reviews from 1997 to 2022 were included. These publications were mainly from 684 journals in 78 countries, led by the United States and China. Kehlet H published the most papers and had the largest number of co-citations. Analysis of the journals with the most outputs showed that most journals mainly cover Surgery and Oncology. The hottest keyword is "enhanced recovery after surgery". Later appearing topics and keywords indicate that the hotspots and future research trends include ERAS protocols for other types of surgery and improving perioperative status, including "bariatric surgery", "thoracic surgery", and "prehabilitation". This study reviewed the research on ERAS using bibliometric and visualization methods, which can help scholars better understand the dynamic evolution of ERAS and provide directions for future research.

TÉCNICA DE ABOMASOTOMÍA PARA LA EXTRACCIÓN DE Haemonchus contortus EN CABRAS VIVAS

&lt;p&gt;&lt;strong&gt;Background:&lt;/strong&gt; Goats are increasingly being used as surgical models in animal experiments. Some ruminant parasitological studies require collecting adult nematodes directly from the abomasum of donor animals. A methodology to collect those adult worms &lt;em&gt;in vivo&lt;/em&gt; could avoid the unnecessary sacrifice of donor animals. &lt;strong&gt;Objective:&lt;/strong&gt; To describe an abomasotomy technique to obtain adult &lt;em&gt;Haemonchus contortus &lt;/em&gt;from live goats and evaluate the immediate post-surgical recovery time. &lt;strong&gt;Methodology:&lt;/strong&gt; Nine worm-free adult goats were infected with 6000 &lt;em&gt;H. contortus &lt;/em&gt;L3. The monospecific infection was confirmed on day 28 post-infection. The anesthetic procedure included fentanyl (10 μg * kg BW&lt;sup&gt;-1&lt;/sup&gt; load dose (LD) and 10 μg * kg BW&lt;sup&gt;-1&lt;/sup&gt; hour in constant-rate-infusion (CRI), lidocaine (2 mg * kg LD&lt;sup&gt;-1&lt;/sup&gt; and 50 μg * kg BW&lt;sup&gt;-1 &lt;/sup&gt;minute CRI), ketamine (1.5 mg * kg&lt;sup&gt;-1&lt;/sup&gt; and 50 μg * kg BW&lt;sup&gt;-1&lt;/sup&gt; min CRI) and propofol (4 mg * kg LD&lt;sup&gt;-1&lt;/sup&gt; and 0.4 mg * kg BW&lt;sup&gt;-1&lt;/sup&gt; min CRI). The surgical protocol consisted of eight “surgical time-points”. Purposeful animal movement in response to surgical stimulation, or any changes in the autonomic response (&amp;gt; 20% from baseline values of HR and arterial blood pressure (SAP, MAP, and DAP)) were used as criteria to identify trans-surgical nociception. Post-surgical pain was evaluated once daily with the wound healing evaluation. &lt;strong&gt;Results:&lt;/strong&gt; The surgical protocol lasted 1 h, allowing the recovery of adult &lt;em&gt;H. contortus &lt;/em&gt;from live goats. The anesthetic protocol successfully controlled trans-surgical pain, with only two animals crossing the HR threshold (&amp;gt;20%) from T2 to T6. Post-surgical recovery (“time to extubation” and “time to standing”) was achieved before 1 h, while animals consumed water after only 4 h post-surgery. Goats did not require rescue analgesia, and suture withdrawal was achieved 7 days post-surgery without complications. &lt;strong&gt;Impications:&lt;/strong&gt; The abomasotomy technique here described can be used for parasitological studies in small ruminants when the collection of nematodes is required from live animals. &lt;strong&gt;Conclusions:&lt;/strong&gt; The anesthetic and surgical protocol here described is a viable and rapid alternative for the collection of nematodes from the abomasum of live goats with minimal pain and rapid postsurgical recovery. &lt;/p&gt;

Assessing biomarkers for post-surgical wound healing: A meta-analysis of exosome-based CircRNA in breast cancer recovery.

To evaluate the diagnostic potential of exosome-based circular RNAs (circRNAs) as biomarkers for wound healing in patients after breast cancer surgery, we conducted a comprehensive meta-analysis of studies that measured exosome-based circRNA levels in breast cancer patients post-surgery. Data sources included several biomedical databases up to April 2023. Two independent reviewers extracted the data and assessed study quality. Sensitivity, specificity and diagnostic odds ratios were synthesized using random-effects model with subgroup analyses performed based on study characteristics. Seventeen studies met the inclusion criteria, encompassing a total of 1234 patients. The pooled sensitivity and specificity of exosome-based circRNA for detecting wound healing complications were 0.85 (95% CI: 0.77-0.91) and 0.83 (95% CI: 0.78-0.88), respectively. The area under the summary receiver operating characteristic (SROC) curve was 0.90, indicating high diagnostic accuracy. Subgroup analyses revealed that diagnostic performance was consistent across studies of different geographic regions and sample types but indicated potential variability related to patient age and study design. Exosome-based circRNA profiles exhibited the high diagnostic accuracy for monitoring wound healing in breast cancer post-operative care. These findings supported the potential utility of circRNA as non-invasive biomarkers for post-surgical recovery. However, variability among studies suggested the need for standardized protocols in biomarker measurement. Future research should focus on longitudinal studies to validate the prognostic value of these biomarkers and investigate their role in personalized patient management.

Evaluation of Post-Surgical Recovery in Olive Flounder (Paralichthys olivaceus) by Assessing Behavior, Heart Rate, and Wound Healing

This study examined the post-surgery recovery of olive flounder (Paralichthys olivaceus) following tag insertion by analyzing behavior, heart rate, and wound healing. The experiments used 30 individuals (length: 38.67 ± 2.12 cm; weight: 742.48 ± 116.41 g). Heart rate was measured using a DST milli-HRT (Star-Oddi) bio-logger. To assess the influence of water temperature on the recovery process after surgical tag insertion, behavioral analyses, heart rate, and wound healing were conducted in two experimental groups: Experiment 1 (22 °C, optimal water temperature); Experiment 2 (28 °C, high water temperature); and control group (22 °C, non-operated fish). The experiment was repeated twice over a 7-day period for each experimental group. Compared to the non-operated fish, the operated fish exhibited stable levels after the 3rd to 4th day in Experiment 1. Statistical analyses based on heart rate in Experiment 1 indicated that the appropriate post-surgery recovery time point was approximately 3 days, representing the point at which behavioral fluctuations stabilized. In the case of Experiment 2, abnormal behavioral patterns (e.g., tilted swimming) and changes in average swimming time and daily heart rate were found to stabilize after 4 days post-surgery.

The Vagus Nerve Regulates Immunometabolic Homeostasis in the Ovine Fetus near Term: The Impact on Terminal Ileum.

Glucosensing elements are widely distributed throughout the body and relay information about circulating glucose levels to the brain via the vagus nerve. However, while anatomical wiring has been established, little is known about the physiological role of the vagus nerve in glucosensing. The contribution of the vagus nerve to inflammation in the fetus is poorly understood. Increased glucose levels and inflammation act synergistically when causing organ injury, but their interplay remains incompletely understood. We hypothesized that vagotomy (Vx) will trigger a rise in systemic glucose levels and this will be enhanced during systemic and organ-specific inflammation. Efferent vagus nerve stimulation (VNS) should reverse this phenotype. Near-term fetal sheep (n = 57) were surgically prepared using vascular catheters and ECG electrodes as the control and treatment groups (lipopolysaccharide (LPS), Vx + LPS, Vx + LPS + selective efferent VNS). The experiment was started 72 h postoperatively to allow for post-surgical recovery. Inflammation was induced with LPS bolus intravenously (LPS group, 400 ng/fetus/day for 2 days; n = 23). For the Vx + LPS group (n = 11), a bilateral cervical vagotomy was performed during surgery; of these n = 5 received double the LPS dose, LPS800. The Vx + LPS + efferent VNS group (n = 8) received cervical VNS probes bilaterally distal from Vx in eight animals. Efferent VNS was administered for 20 min on days 1 and 2 +/10 min around the LPS bolus. Fetal arterial blood samples were drawn on each postoperative day of recovery (-72 h, -48 h, and -24 h) as well as at the baseline and seven selected time points (3-54 h) to profile inflammation (ELISA IL-6, pg/mL), insulin (ELISA), blood gas, and metabolism (glucose). At 54 h post-LPS, a necropsy was performed, and the terminal ileum macrophages' CD11c (M1 phenotype) immunofluorescence was quantified to detect inflammation. The results are reported for p < 0.05 and for Spearman R2 > 0.1. The results are presented as the median (IQR). Across the treatment groups, blood gas and cardiovascular changes indicated mild septicemia. At 3 h in the LPS group, IL-6 peaked. That peak was decreased in the Vx + LPS400 group and doubled in the Vx + LPS800 group. The efferent VNS sped up the reduction in the inflammatory response profile over 54 h. The M1 macrophage activity was increased in the LPS and Vx + LPS800 groups only. The glucose and insulin concentrations in the Vx + LPS group were, respectively, 1.3-fold (throughout the experiment) and 2.3-fold higher vs. control (at 3 h). The efferent VNS normalized the glucose concentrations. The complete withdrawal of vagal innervation resulted in a 72-h delayed onset of a sustained increase in glucose for at least 54 h and intermittent hyperinsulinemia. Under the conditions of moderate fetal inflammation, this was related to higher levels of gut inflammation. The efferent VNS reduced the systemic inflammatory response as well as restored both the concentrations of glucose and the degree of terminal ileum inflammation, but not the insulin concentrations. Supporting our hypothesis, these findings revealed a novel regulatory, hormetic, role of the vagus nerve in the immunometabolic response to endotoxin in near-term fetuses.

Postsurgical Recovery and Long-Term Outcomes: What Should We Be Measuring?

Postsurgical Recovery and Long-Term Outcomes: What Should We Be Measuring?

A Review of the Application of Myofascial Release Therapy in the Treatment of Diseases.

Myofascial release (MFR) therapy is widely used in clinical practice to treat various musculoskeletal and pain-related conditions. However, there is a lack of comprehensive reviews that systematically evaluate its effectiveness across different medical conditions, leading to inconsistent applications and understanding of its therapeutic potential. This review aims to synthesize the current applications of myofascial release therapy in the treatment of various diseases, highlighting its efficacy and identifying areas where further research is needed. The review covers the application of myofascial release therapy in conditions such as chronic pain, fibromyalgia, post-surgical recovery, and neurological disorders. It evaluates the outcomes of existing studies, identifies gaps in the literature, and discusses the mechanisms through which myofascial release exerts its effects. Additionally, the review provides insights into the limitations of current research and suggests directions for future studies to enhance the clinical application of myofascial release therapy.

Whole Blood Reactivity to Viral and Bacterial Pathogens after Non-Emergent Cardiac Surgery during the Acute and Convalescence Periods Demonstrates a Distinctive Profile of Cytokines Production Compared to the Preoperative Baseline in Cohort of 108 Patients, Suggesting Immunological Reprogramming during the 28 Days Traditionally Recognized as the Post-Surgical Recovery Period.

The release of danger signals from tissues in response to trauma during cardiac surgery creates conditions to reprogram the immune system to subsequent challenges posed by pathogens in the postoperative period. To demonstrate this, we tested immunoreactivity before surgery as the baseline (tbaseline), followed by subsequent challenges during the acute phase (t24h), convalescence (t7d), and long-term recovery (t3m). For 108 patients undergoing elective heart surgery, whole blood was stimulated with lipopolysaccharide (LPS), Influenza A virus subtype N2 (H3N2), or the Flublok™ vaccine to represent common pathogenic challenges. Leukocytosis, platelet count, and serum C-reactive protein (CRP) were used to measure non-specific inflammation. Cytokines were measured after 18 h of stimulation to reflect activation of the various cell types (activated neutrophils-IL-8; activated T cells-IL-2, IFNγ, activated monocyte (MO)-TNFα, IL-6, and deactivated or atypically activated MO and/or T cells-M-CSF, IL-10). IL-2 and IL-10 were increased at t7d, while TNFα was suppressed at t24h when LPS was utilized. Interestingly, M-CSF and IL-6 production was elevated at seven days in response to all stimuli compared to baseline. While some non-specific markers of inflammation (white cell count, IL-6, and IL-8) returned to presurgical levels at t3m, CRP and platelet counts remained elevated. We showed that surgical stimulus reprograms leukocyte response to LPS with only partial restoration of non-specific markers of inflammation.

The use of preoperative continuous positive airway pressure in patients with obstructive sleep apnea following total hip arthroplasty: A propensity score matched analysis

IntroductionObstructive sleep apnea (OSA) impacts approximately 936 million individuals globally and is known to complicate post-surgical recovery, particularly after total hip arthroplasty (THA). While continuous positive airway pressure (CPAP) is commonly recommended for managing OSA, its effect on THA recovery remains uncertain. The study aimed to assess the impact of CPAP use on post-THA outcomes in patients with OSA, focusing on medical complications and periprosthetic joint infection (PJI) at 90 days and 1 year. MethodsA national, all-payer database was utilized to identify patients undergoing primary THA between 2010 and 2021. Patients with OSA were stratified based on CPAP use through propensity score matching. Three matched groups were formed: OSA without CPAP, OSA with CPAP, and no OSA. Medical and surgical complications were assessed at 90 days and 1 year post-THA. ResultsPatients with OSA using CPAP exhibited more baseline comorbidities than those without CPAP. CPAP use was associated with inferior outcomes, including higher odds of PJI, wound complications, and venous thromboembolism at 90 days and 1 year post-THA. These trends were consistent even after adjusting for confounders. ConclusionCPAP use, indicative of severe OSA, was linked to worse post-THA outcomes, emphasizing the importance of recognizing OSA severity preoperatively. The study does not advocate for or against CPAP use but underscores the heightened risk in this patient population, guiding clinicians in tailoring perioperative strategies and counseling patients about potential risks.

Characterizing mJOA-defined post-surgical recovery patterns in patients with degenerative cervical myelopathy

BackgroundDegenerative cervical myelopathy is a spinal disorder resulting in progressive cord compression and neurological deficits that are assessed using the modified Japanese Orthopedic Association (mJOA) questionnaire. It is difficult to predict which patients will recover neurological function after surgery, making it challenging for clinicians to set postoperative patient expectations. In this study, we used mJOA subscores to identify patterns of recovery and recovery timelines in patients with moderate and severe myelopathy. MethodsFifty-three myelopathy patients were enrolled and completed the mJOA questionnaire both pre-surgery, and six weeks and six months post-surgery. Pearson chi-square tests were performed to assess relationships of both recovery patterns and recovery timelines with severity of disease. ResultsModerate myelopathy patients were significantly more likely than severe myelopathy patients to experience full recovery of upper extremity, lower extremity, and sensory domains. Disease severity did not significantly impact the timeline during which recovery occurs. Overall, >90% of patients experienced at least partial recovery by six months post surgery, 80% of which demonstrated it within the first six weeks. ConclusionsThis study shows the more severe the disease experienced by myelopathy patients, the more likely they will be left with permanent disabilities despite surgery. Early identification and treatment are therefore necessary to prevent worsening quality of life and increased costs of functional dependence. The recovery timelines for each subscore are similar and provide new values to guide patient expectations in their potential post-operative recovery. The overall recovery timeline is more generalizable though potentially lacking the specificity patients seek.

J147 affects cognition and anxiety after surgery in Zucker rats

Vulnerable patients are at risk for neuroinflammation-mediated post-operative complications, including depression (POD) and cognitive dysfunction (POCD). Zucker rats, expressing multiple risk factors for post-operative complications in humans, may provide a clinically relevant model to study pathophysiology and explore potential interventions. J147, a newly developed anti-dementia drug, was shown to prevent POCD in young healthy rats, and improved early post-surgical recovery in Zucker rats. Aim of the present study was to investigate POCD and the therapeutic potential of J147 in male Zucker rats.Risk factors in the Zucker rat strain were evaluated by comparison with lean littermates. Zucker rats were subjected to major abdominal surgery. Acute J147 treatment was provided by a single iv injection (10 mg/kg) at the start of surgery, while chronic J147 treatment was provided in the food (aimed at 30 mg/kg/day), starting one week before surgery and up to end of protocol. Effects on behavior were assessed, and plasma, urine and brain tissue were collected and processed for immunohistochemistry and molecular analyses.Indeed, Zucker rats displayed increased risk factors for POCD, including obesity, high plasma triglycerides, low grade systemic inflammation, impaired spatial learning and decreased neurogenesis. Surgery in Zucker rats reduced exploration and increased anxiety in the Open Field test, impaired short-term spatial memory, induced a shift in circadian rhythm and increased plasma neutrophil gelatinase-associated lipocalin (NGAL), microglia activity in the CA1 and blood brain barrier leakage. Chronic, but not acute J147 treatment reduced anxiety in the Open Field test and protected against the spatial memory decline. Moreover, chronic J147 increased glucose sensitivity. Acute J147 treatment improved long-term spatial memory and reversed the circadian rhythm shift. No anti-inflammatory effects were seen for J147.Although Zucker rats displayed risk factors, surgery did not induce extensive POCD. However, increased anxiety may indicate POD. Treatment with J147 showed positive effects on behavioral and metabolic parameters, but did not affect (neuro)inflammation. The mixed effect of acute and chronic treatment may suggest a combination for optimal treatment.

Do passive range of motion exercises lead to quicker postsurgical recovery of canine IVDD?

PICO Question In canine patients recovering from surgery for intervertebral disc disease, do passive range of motion exercises, compared to no intervention, lead to a shorter or faster rate of recovery? Clinical bottom line Category of research Treatment. Number and type of study designs reviewed Five studies (two randomised controlled trials, two retrospective cohort studies and one retrospective case series) were critically appraised. Strength of evidence Weak. Outcomes reported There is no evidence that passive range of motion (PROM) exercises are associated with a quicker postsurgical recovery in the canine intervertebral disc disease (IVDD) patient. Conclusion There is a lack of evidence about specific rehabilitation techniques for the postoperative canine IVDD patient. Based on the current data, a multimodal approach, including basic and intense rehabilitation techniques is suggested. How to apply this evidence in practice The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources. Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care.

Self-Administered Virtual Reality for Postsurgical Pain Management: A Qualitative Study of Hospital Patients' Reported Experiences.

Virtual Reality (VR) has been shown to effectively reduce pain in patients with various pain conditions. However, questions arise on the use of VR in multimodal postsurgical pain management. Optimizing VR for pain management requires an understanding of intervention- and context-specific factors, based on patients' needs and expectations after major surgery. This substudy is part of a randomized controlled trial investigating the effects of three VR interventions as an add-on, self-administered treatment for postsurgical pain. Semi-structured interviews were conducted to evaluate VR effects, software, hardware, prescriptions, and factors affecting the implementation of VR. Experiences across interventions were compared to identify relevant factors for successful implementation. Patients benefitted from self-administered VR in postsurgical pain management in various aspects and without serious drawbacks. Participants preferred an intuitive, 3D, 360-degree VR device with a large choice of applications matching their interests. The preferred frequency and duration of VR use was 2-3 sessions a day for 10-15 min each. Adjusting the VR use to individuals' needs and contexts was reported to be key for successful implementation, with attention paid to improving the awareness of VR as a non-pharmacological means of promoting postsurgical recovery among patients and healthcare professionals.

Comparison of Satisfaction Levels Between Post-Operative Sectio Caesaria Patients Followed by the Eracs Protocol TAP Block Analgesia Method and IV Patient Controlled Analgesia: A Literature Review

Purpose: This paper aims to examine the results of the past ten years of research related to the satisfaction levels of postoperative sectio cesarea patients followed by the ERACS protocol TAP block analgesia method and IV patient-controlled analgesia. Theoretical framework: Cesarean section is one of the most common methods of delivery in the world. The enhancement of public interest in the cesarean section has also increased perioperative services. In order to increase the clinical benefits of cesarean section, enhanced recovery care is an effective way to do it. ERACS (Enhanced Recovery After Caesarian Surgery) is a fast recovery program after a cesarean section in the form of a series of treatments to improve post-surgical recovery. These conditions make expectations related to patient comfort and satisfaction during treatment. Design/Methodology/Approach: The method used in the preparation of a literature review is to search for several articles by searching through science direct, google scholar, and Pubmed. Findings: The results of 20 previous research articles showed that Enhanced recovery after surgery (ERAS) in cesarean section showed the results that standardizing postoperative patient care, improving patient outcomes, reducing the postoperative length of stay, and optimizing patient satisfaction. Research, Practical &amp; Social implications: In postoperative management of the ERAS method, there are various methods, including regional block analgesia and patient-controlled analgesia. TAP block and PCA effectively relieve postoperative pain after cesarean section. Originality/Value: This paper shows a large number of alternatives and the choice of post-cesarean section analgesic methods and drugs with the ERACS protocol means that pharmacology and anesthesia must be accompanied by aspects of patient satisfaction surveys which play a role in selecting the most effective drug or analgesic method.

Orally administered Chinese herbal therapy to assist post-surgical recovery for chronic rhinosinusitis-A systematic review and meta-analysis.

This systematic review and meta-analysis aims to: assess the effectiveness and safety of orally administered Chinese herbal medicines (CHMs) as adjuncts to the post-surgical management of chronic rhinosinusitis (CRS); inform clinicians of the current evidence; identify the best available evidence; and suggest directions for further research. Randomised controlled trials (RCTs) were identified from searches of nine databases plus clinical trial registries. Participants were adults and/or children diagnosed with sinusitis or rhinosinusitis, with or without nasal polyps, who had received surgery. Interventions were CHMs used orally following surgery for CRS as additions to conventional post-surgical management. Controls received conventional post-surgical management without CHMs. Studies reported results for Sino-Nasal Outcome Test (SNOT), visual analogue scales (VAS), Lund-Mackay computed tomography score (LM), Lund-Kennedy endoscopic score (LK), mucociliary transport time (MTT), mucociliary transport rate (MTR), mucociliary clearance (MC) or quality of life (QoL). Twenty-one RCTs were included. All used oral CHMs following functional endoscopic sinus surgery (FESS). The pooled results showed no significant difference between groups for SNOT-20 at the end of treatment (EoT) but there was a significant difference at follow up (FU) in favour of additional CHMs. The VAS for total nasal symptoms (VAS-TNS) showed greater improvements in the CHM groups at EoT and FU. Only FU data were reported for LM which showed greater improvement in the CHM groups. LK showed greater improvements at EoT and FU. The measures of mucociliary transport (MTT, MTR, and MC) each showed significantly greater improvement at EoT in the group that received additional CHMs. No study reported QoL. Adverse events were not serious, but reporting was incomplete. The meta-analyses suggested the addition of oral CHMs to conventional management following FESS may improve recovery. However, most studies were not blinded, and substantial heterogeneity was evident in some meta-analyses. Blinded studies are required to further investigate the roles of oral CHMs in post-surgical recovery. Systematic review registration number: The protocol was registered in PROSPERO (CRD42019119586).

Absorbable vs Nonabsorbable Sutures for Achilles Tendon Repair: A Systematic Review and Meta-analysis.

Nonabsorbable sutures are still the main choice for acute Achilles tendon rupture (AATR) repair due to strength provided. However, the rerupture rates, infection risks, foreign body reaction, and postsurgical recovery differences between absorbable and nonabsorbable suture materials in AATR repair have not been carefully reviewed. A systematic review was done on PubMed, EBSCO, Cochrane Central Register of Controlled Trials, and Embase to find research studies in relation to complications associated with AATR repair using the PRISMA guidelines. The risk of bias from each study included will be assessed using the Cochrane Risk of Bias Tool for randomized study (RoB 2) and Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) for nonrandomized study. Five studies with a total of 255 patients, 105 in the absorbable suture group and 150 in the nonabsorbable suture group, were included for analysis. Risk of rerupture, infection, and foreign body reaction shown no significant difference between groups, and the mean difference of recovery scores were similar. Existing literature shows that absorbable sutures appear to be associated with similar outcomes to nonabsorbable sutures regarding rates of rerupture, infection, foreign body reaction, and outcomes grading following surgical repair of acute Achilles tendon repair.

P01.11.A MECHANISMS OF LANGUAGE PLASTICITY IN PATIENTS HARBORING LEFT HEMISPHERE GLIOMAS

Abstract BACKGROUND Infiltrating gliomas are slow growing intrinsic brain lesions that have been shown to induce functional reorganization, although the mechanisms by which this occurs are not well understood. The present study examines glioma-induced neuroplasticity of language networks to investigate this phenomenon. MATERIAL AND METHODS 117 patients’ fMRI scans were analyzed from patients harboring gliomas whom completed 1-5 fMRI language tasks. Data was analyzed via two methods: cluster-based and cortical/subcortical mask-based. Right hemisphere gliomas (RHG) (n=40) were first analyzed to establish a reliable control group by determining statistically significant voxels across all five language tasks (LT), yielding a core conserved network. The language network induced by left hemisphere gliomas (LHG) (n=77) was then directly compared to the RHG language network to examine language plasticity. RESULTS LHG induced global reorganization of the canonical language network, including preserved homologous and novel left hemisphere (LH) and right hemisphere (RH) activation clusters. In each of the five LT, the LHG group showed activation of fewer total suprathreshold voxels in both the cluster (3 fewer clusters and 38,892 fewer active voxels/task) and mask-based (8 fewer active masks/task and 91,965 fewer active voxels/task) analyses while having a higher peak intensity (5.4 total increase in zmax) within the activated clusters. In addition, a generalized pattern of increased RH recruitment was seen in LHG patients, with 87% (137/157) of non-zero masks shifting their laterality index (LI) to the right hemisphere. These data suggest that the reorganized LHG-induced language network functions through less nodes along with a rightward shift of language lateralization. In addition, a subgroup analysis of frontal (n=16) and temporal (n=32) LHG revealed that frontal tumors promote increased RH activation relative to temporal tumors, with 94% (32/34) of non-zero masks shifting their LI to the RH compared to 68% (23/34), respectively. Frontal tumors also preferentially recruit the contralateral (RH) frontal lobe and ipsilateral (LH) temporal lobe, while temporal gliomas preferentially recruit the ipsilateral frontal lobe. CONCLUSION Infiltrating tumors within the left hemisphere promote language plasticity via consolidation of the classical LH language network along with recruitment of previously silent, novel language areas in the right and left hemispheres. This improved understanding of patterns of language plasticity may aid in more accurate pre-surgical risk stratification and counseling, therapeutic targeting for post-surgical recovery, and intelligent “pre-habilitation” strategies to maximize neuroplasticity prior to tumor resection.
