Abstract
BACKGROUND The effect of early isoenergetic feeding routes [early enteral nutrition (E-EN) or early supplemental parenteral nutrition (E-SPN)] on the outcome of patients undergoing major abdominal surgery is controversial. OBJECTIVES The aim of this study was to investigate the impact of early isoenergetic EN compared with early isoenergetic SPN on nosocomial infections in patients undergoing major abdominal surgery. METHODS This study is a secondary, post hoc analysis of data from 2 open-label randomized clinical trials. Participants were recruited from the general surgery department of 11 academic hospitals in China undergoing major abdominal surgery and with Nutritional Risk Screening 2002 score ≥3. All eligible patients were categorized into 2 groups based on their achievement of the 100% energy target on postoperative day (POD) 3: the E-EN group (n = 199) and the E-SPN group (n = 115). The primary outcome was the incidence of nosocomial infections between POD 3 and hospital discharge. RESULTS In total, 314 patients [mean (SD) age, 59.2 (11.4) y; 113 (36.0%) females] were included. Patients in the E-EN group showed no significant difference in nosocomial infections compared with those in the E-SPN group {17/199 [8.5%] compared with 10/115 [8.7%], risk difference, 0.2% [95% confidence interval (CI): -6.3, 6.6]}. The hematological nutritional status of the E-EN group showed a significant improvement at discharge compared with the E-SPN group (albumin: 38.0 ± 6.0 g/L compared with 35.5 ± 7.6 g/L; mean difference, -2.5 g/L; 95% CI: -4.0, -1.0 g/L; prealbumin: 200.0 ± 8.0 mg/L compared with 158.4 ± 38.1 mg/L; mean difference, -41.6 mg/L; 95% CI: -41.7, -36.1 mg/L). Other indicators were comparable between groups. CONCLUSION E-EN compared with isoenergetic SPN may not be associated with a reduced rate of nosocomial infection in patients undergoing major abdominal surgery, but may be associated with improved hematological nutritional status. TRIAL REGISTRATION NUMBER This trial was registered at clinicaltrials.gov as NCT03115957 (https://clinicaltrials.gov/ct2/show/NCT03115957) and NCT03117348 (https://clinicaltrials.gov/ct2/show/NCT03117348).

Abstract
OBJECTIVE To describe immune pathways and gene networks altered following major abdominal surgery and to identify transcriptomic patterns associated with postoperative pneumonia. BACKGROUND Nosocomial infections are a major healthcare challenge, developing in over 20% of patients aged 45 or over undergoing major abdominal surgery, with postoperative pneumonia associated with an almost 5-fold increase in 30-day mortality. METHODS From a prospective consecutive cohort (n=150) undergoing major abdominal surgery, whole-blood RNA was collected preoperatively and at 3 time-points postoperatively (2-6, 24, and 48 h). Twelve patients diagnosed with postoperative pneumonia and 27 matched patients remaining infection-free were identified for analysis with RNA-sequencing. RESULTS Compared to preoperative sampling, 3639 genes were upregulated and 5043 downregulated at 2 to 6 hours. Pathway analysis demonstrated innate-immune activation with neutrophil degranulation and Toll-like-receptor signaling upregulation alongside adaptive-immune suppression. Cell-type deconvolution of preoperative RNA-sequencing revealed elevated S100A8/9-high neutrophils alongside reduced naïve CD4 T-cells in those later developing pneumonia. Preoperatively, a gene-signature characteristic of neutrophil degranulation was associated with postoperative pneumonia acquisition ( P =0.00092). A previously reported Sepsis Response Signature (SRSq) score, reflecting neutrophil dysfunction and a more dysregulated host response, at 48 hours postoperatively, differed between patients subsequently developing pneumonia and those remaining infection-free ( P =0.045). Analysis of the novel neutrophil gene-signature and SRSq scores in independent major abdominal surgery and polytrauma cohorts indicated good predictive performance in identifying patients suffering later infection. CONCLUSIONS Major abdominal surgery acutely upregulates innate-immune pathways while simultaneously suppressing adaptive-immune pathways. This is more prominent in patients developing postoperative pneumonia. Preoperative transcriptomic signatures characteristic of neutrophil degranulation and postoperative SRSq scores may be useful predictors of subsequent pneumonia risk.

Abstract
BACKGROUND Major abdominal surgery (MAS) can have a profound impact on the patient but there is currently no consensus as to which surgical procedures constitute MAS. The main objective of this work is to ascertain the terminology used to describe MAS procedures and to apply these findings in order to propose a definition of MAS. METHODS The following databases were searched: Ovid MEDLINE (R) ALL, Embase Classic and Embase (via OvidSP), Global Health (via OvidSP), Health Management Information Consortium (via OvidSP), APA PsycInfo (via OvidSP), PubMed and Web of Science. Original research articles, published between 1980 and April 26, 2022 that contained a description of MAS procedure were included in this study. Article screening and data extraction was undertaken independently by 3 authors. Content analysis was performed to identify key terminology used to describe MAS. RESULTS Five thousand six hundred and sixty three articles were identified, of which 767 underwent full-text review and 312 were included in the scoping review. Content analysis resulted in 4 main categories: (1) pre-operative factors, (2) intraoperative factors, (3) operation-related factors, (4) post-operative factors. Operation-related factors was the predominant category (1137 references coded). The gastrointestinal resection made the vast majority of the references coded (591). CONCLUSIONS Based on these results, the term "major abdominal surgery" should be defined as an intra-peritoneal operation with no primary involvement of the thorax, involving either luminal resection and/or resection of a solid organ associated with the gastrointestinal tract. However, further work is required to verify this definition using real world data.

Abstract
Background and Aims Thoracic continuous spinal anaesthesia (TCSA) is emerging as the sole anaesthetic for major abdominal surgery due to its better perioperative outcomes. This study was designed to evaluate block characteristics and outcomes in 'opioid-free' and 'opioid-based' TCSA. Methods After ethical approval, trial registration and written informed consent, 50 adult patients undergoing major abdominal surgery were randomised into 'opioid-free' (bupivacaine alone) and 'opioid-based' (bupivacaine with fentanyl) groups. After confirmation of T4-L1 dermatome level of spinal anaesthesia, sedation by intravenous (IV) midazolam (0.02-0.05 mg/kg), ketamine (0.25 mg/kg) and dexmedetomidine (bolus dose of 1 µg/kg IV over 10 min followed by 0.2-0.7 µg/kg/h infusion) were started. The primary outcome measured was postoperative pain scores for 72 h in both groups. The secondary objectives were rescue opioid requirement, and the dose of bupivacaine required to achieve T4 level. Data were compared using the two-sided Student t-test, Mann-Whitney and Fisher's exact tests. Results The 'opioid-based' group performed significantly better compared with the 'opioid-free' group concerning pain scores at rest at 0 h (P = 0.023), 18 h (P = 0.023) and 24 h (P = 0.016) postoperatively, decreased intrathecal bupivacaine requirement [(induction (P = 0.012) and maintenance (P = 0.031)], postoperative rescue fentanyl requirement (P = 0.018) and patient satisfaction (P = 0.032) at the cost of increased postoperative nausea and vomiting (P = 0.049). Conclusion The 'opioid-based' TCSA provided better postoperative analgesia with significantly lesser postoperative pain scores when compared to the 'opioid-free' group in patients undergoing major abdominal surgery.

Abstract
BACKGROUND The association between malnutrition and postoperative acute kidney injury (AKI) has not been well studied. In this study, the authors examined the association between preoperative nutritional status and postoperative AKI in older patients who underwent major abdominal surgery, as well as the predictive value of malnutrition for AKI. MATERIALS AND METHODS The authors retrospectively included patients aged 65 or older who underwent major elective abdominal surgery. The nutritional status of the patient was evaluated using three objective nutritional indices, such as the geriatric nutritional risk index (GNRI), the prognostic nutritional index (PNI), and the controlling nutritional status (CONUT). AKI was determined using the KDIGO criteria. The authors performed logistic regression analysis to investigate the association between preoperative nutritional status and postoperative AKI, as well as the predictive value of nutritional scores for postoperative AKI. RESULTS A total of 2775 patients were included in the study, of which 707 (25.5%), 291 (10.5%), and 517 (18.6%) had moderate to severe malnutrition according to GNRI, PNI, and CONUT calculations. After surgery, 144 (5.2%) patients developed AKI, 86.1% at stage 1, 11.1% at stage 2, and 2.8% at stage 3 as determined by KDIGO criteria. After adjustment for traditional risk factors, worse nutritional scores were associated with a higher AKI risk. In addition to traditional risk factors, these nutritional indices improved the predictive ability of AKI prediction models, as demonstrated by significant improvements in integrated discrimination and net reclassification. CONCLUSIONS Poor preoperative nutritional status, as assessed by GNRI, PNI, and CONUT scores, was associated with an increased risk of postoperative AKI. Incorporating these scores into AKI prediction models improved their performance. These findings emphasize the need for screening surgical patients for malnutrition risk. Further research is needed to determine whether preoperative malnutrition assessment and intervention can reduce postoperative AKI incidence.

Abstract
Pituitary apoplexy is a major complication of pituitary adenoma, and the diagnosis might be challenging if the patient presents with signs of meningeal irritation or electrolyte imbalance. It can be fatal if not diagnosed and treated appropriately. Apoplexy is the first clinical presentation in the majority of pituitary adenoma cases. The pathophysiology of pituitary apoplexy involves bleeding and/or ischemia of pituitary enlargement. In this case report, we present a case of pituitary apoplexy that developed after a major abdominal surgery. The patient presented with headache, hypertension, and visual loss. After confirming the diagnosis through a CT scan, the patient underwent a transsphenoidal surgical decompression.

Abstract
This randomized-controlled trial aimed to investigate the effect of bed exercises on postoperative anxiety, pain, early ambulation and mobilization. This study was conducted with a randomized-controlled trial design and in the general surgical clinic of a research and training hospital. A total of 120 patients (60 in the experimental group and 60 in the control group) scheduled for major abdominal surgery took part in the study. The data were collected using a patient information form, the Anxiety Specific to Surgery Questionnaire and the Visual Analog Scale through face-to-face interviews. The patients in the experimental group performed 15-min bed exercises on the day of their operation, as well as on the postoperative first and second days, and the control group underwent only the routinely performed procedures in the clinic. The data were analysed using descriptive statistics, analysis of variance and t-tests. The sample of our study included major abdominal surgery patients. Ambulation was achieved at a mean time of 4 h earlier in the experimental group. On the postoperative first and second days, the patients in the experimental group had mean mobilization durations that were approximately 2 h longer compared with the patients in the control group. Moreover, the postoperative pain and anxiety levels of the patients in the experimental group were significantly lower than those of the patients in the control group (p < 0.05). We recommend that bed exercises be performed to lower anxiety and pain severity, achieve early ambulation and increase the duration of mobilization among patients following major abdominal surgery.

Abstract
OBJECTIVES Postoperative delirium (POD) is a common postsurgical complication. The early identification of its risk factors is the first step toward reducing POD. The predictive factors for POD in patients after major abdominal surgery remain obscure. Therefore, this meta-analysis aimed to comprehensively summarize the risk factors of POD after major abdominal surgery. METHODS POD studies published between January, 1900 and June 2022 were obtained by searching PubMed, Cochrane Library, Web of Science, Embase, and Medline. Two authors independently reviewed the studies to extract the risk factors and assessed the quality of related articles using the Newcastle-Ottawa Scale. Data were recorded, and a meta-analysis was performed using Review Manager version 5.4.1. RESULTS Ten studies including total 2900 patients undergoing major abdominal surgery, were eligible for analysis, 608 of whom developed POD, for a cumulative incidence of 21%. This pooled analysis suggested the statistically significant risk factors for POD were age, higher American Society of Anesthesiologists grade, lower preoperative Mini-Mental State Examination score, cognitive impairment, preoperative Katz-ADL score <6, preoperative and postoperative hypoalbuminemia, lower preoperative insulin-like growth factor-1 levels, and longer duration of anesthesia. CONCLUSION POD is common in patients undergoing major abdominal surgery. This meta-analysis identified risk factors that may aid the early detection of POD and play a prominent role in preventing POD.

Abstract
BACKGROUND Preoperative telemonitoring of vital signs, physical activity, and well-being might be able to optimize prehabilitation of the patient's physical and mental condition prior to surgery, support setting alarms during in-hospital monitoring, and allow personalization of the postoperative recovery process. OBJECTIVE The primary aim of this study was to evaluate when and how long patients awaiting major abdominal surgery should be monitored to get reliable preoperative individual baseline values of heart rate (HR), daily step count, and patient-reported outcome measures (PROMs). The secondary aim was to describe the perioperative course of these measurements at home. METHODS In this observational single-center cohort study, patients used a wearable sensor during waking hours and reported PROMs (pain, anxiety, fatigue, nausea) on a tablet twice a day. Intraclass correlation coefficients (ICCs) were used to evaluate the reliability of mean values on 2 specific preoperative days (the first day of telemonitoring and the day before hospital admission) and randomly selected preoperative periods compared to individual reference values. Mean values of HR, step count, and PROMs per day were visualized in a boxplot from 14 days before hospital admission until 30 days after surgery. RESULTS A total of 16 patients were included in the data analyses. The ICCs of mean values on the first day of telemonitoring were 0.91 for HR, 0.71 for steps, and at least 0.86 for PROMs. The day before hospital admission showed reliability coefficients of 0.76 for HR, 0.71 for steps, and 0.92-0.99 for PROMs. ICC values of randomly selected measurement periods increased over the continuous period of time from 0.68 to 0.99 for HR and daily step counts. A lower bound of the 95% CI of at least 0.75 was determined after 3 days of measurements. The ICCs of randomly selected PROM measurements were 0.89-0.94. Visualization of mean values per day mainly showed variable preoperative daily step counts (median 2409, IQR 1735-4661 steps/day) and lower postoperative daily step counts (median 884, IQR 474-1605 steps/day). In addition, pain was visually reduced until 30 days after surgery at home. CONCLUSIONS In this prospective pilot study, for patients awaiting major abdominal surgery, baseline values for HR and daily step count could be measured reliably by a wearable sensor worn for at least 3 consecutive days and PROMs during any preoperative day. No clear conclusions were drawn from the description of the perioperative course by showing mean values of HR, daily step count, and PROM values over time in the home situation.

Abstract
Background Associated with increased morbidity and mortality, postoperative pulmonary complications (PPCs) often occur after major abdominal surgery. Diaphragmatic dysfunction is suggested to play an important role in the development of PPCs and diaphragm echodensity can be used as an indicator of diaphragm function. This study aimed to determine whether diaphragm echodensity could predict the occurrence of PPCs in patients after major abdominal surgery. Methods Diaphragm ultrasound images of patients after major abdominal surgery were collected during spontaneous breathing trials. Echodensity was quantified based on the right-skewed distribution of grayscale values (50th percentile, ED50; 85th percentile, ED85; mean, EDmean). Intra- and inter-analyzer measurement reproducibility was determined. Outcomes including occurrence of PPCs, reintubation rate, duration of ventilation, and length of ICU stay were recorded. Results Diaphragm echodensity was measured serially in 117 patients. Patients who developed PPCs exhibited a higher ED50 (35.00 vs. 26.00, p < 0.001), higher ED85 (64.00 vs. 55.00, p < 0.001) and higher EDmean (39.32 vs. 33.98, p < 0.001). In ROC curve analysis, the area under the curve of ED50 for predicting PPCs was 0.611. The optimal ED50 cutoff value for predicting the occurrence of PPCs was 36. According to this optimal ED50 cutoff value, patients were further divided into a high-risk group (ED50 > 36, n = 35) and low-risk group (ED50 ≤ 36, n = 82). Compared with the low-risk group, the high-risk group had a higher incidence of PPCs (unadjusted p = 0.003; multivariate-adjusted p < 0.001). Conclusion Diaphragm echodensity can be feasibly and reproducibly measured in mechanically ventilated patients. The increase in diaphragm echodensity during spontaneous breathing trials was related to an increased risk of PPCs in patients after major abdominal surgery.

Abstract
BACKGROUND Practice patterns related to intraoperative fluid administration and vasopressor use have potentially evolved over recent years. However, the extent of such changes and their association with perioperative outcomes, such as the development of acute kidney injury (AKI), have not been studied. METHODS We performed a retrospective analysis of major abdominal surgeries in adults across 26 US hospitals between 2015 and 2019. The primary outcome was AKI as defined by the Kidney Disease Improving Global Outcomes definition (KDIGO) using only serum creatinine criteria. Univariable linear predictive additive models were used to describe the dose-dependent risk of AKI given fluid administration or vasopressor use. RESULTS Over the study period, we observed a decrease in the volume of crystalloid administered, a decrease in the proportion of patients receiving more than 10 ml kg-1 h-1 of crystalloid, an increase in the amount of norepinephrine equivalents administered, and a decreased duration of hypotension. The incidence of AKI increased between 2016 and 2019. An increase of crystalloid administration from 1 to 10 ml kg-1 h-1 was associated with a 58% decreased risk of AKI. CONCLUSIONS Despite decreased duration of hypotension during the study period, decreased fluid administration and increased vasopressor use were associated with increased incidence of AKI. Crystalloid administration below 10 ml kg-1 h-1 was associated with an increased risk of AKI. Although no causality can be concluded, these data suggest that prevention and treatment of hypotension during abdominal surgery with liberal use of vasopressors at the expense of fluid administration is associated with an increased risk of postoperative AKI.

Abstract
BACKGROUND Telemonitoring during the perioperative trajectory may improve patient outcomes and self-management. The aim of this study is to assess the feasibility of and patient's experiences with telemonitoring before and after major abdominal surgery to inform future study design. METHODS Patients planned for elective major abdominal surgery wore a sensor and answered well-being questions on a tablet daily for at least 2 weeks preoperatively up to 30-days postoperatively. Feasibility was assessed by participation and completion rate, compliance per day, weekly satisfaction scores, and reasons for nonscheduled contact. RESULTS Twenty-three patients were included (participation rate of 54.5%) with a completion rate of 69.6%. Median compliance with the wearable sensor and well-being questions was respectively: 94.7% and 83.3% preoperatively at home; 100% and 66.7% postoperatively in-hospital; and 95.4% and 85.8% postoperatively at home. Median weekly satisfaction scores for both wearing the sensor and well-being questions were 5 (IQR, 4-5). Contact moments were related to absence of sensor data and technological issues (76.0%) or patient discomfort and insecurity (24.0%). CONCLUSIONS In this study, telemonitoring showed high satisfaction and compliance during the perioperative trajectory. Future trial design regarding the effectiveness of telemonitoring requires embedding in clinical practice and support for patients, relatives, and healthcare personnel.

Abstract
Noncardiac surgery is associated with hemodynamic perturbations, fluid shifts and hypoxic events, causing stress responses. Copeptin is used to assess endogenous stress and predict myocardial injury. Myocardial injury is common after noncardiac surgery, and is often caused by myocardial oxygen demand-and-supply mismatch. In this secondary analysis, we included 173 patients at risk for cardiovascular complications undergoing moderate- to high-risk major abdominal surgery. Patients were randomly assigned to receive 80% or 30% oxygen throughout surgery and the first two postoperative hours. We evaluated the effect of supplemental oxygen on postoperative Copeptin concentrations. Copeptin concentrations were measured preoperatively, within two hours after surgery, on the first and third postoperative days. In total, 85 patients received 0.8 FiO2, and 88 patients received 0.3 FiO2. There was no significant difference in postoperative Copeptin concentrations between both study groups (p = 0.446). Copeptin increased significantly within two hours after surgery, compared with baseline in the overall study population (estimated effect: −241.7 pmol·L−1; 95% CI −264.4, −219.1; p < 0.001). Supplemental oxygen did not significantly attenuate postoperative Copeptin release. Copeptin concentrations showed a more immediate postoperative increase compared with previously established biomarkers. Nevertheless, Copeptin concentrations did not surpass Troponin T in early determination of patients at risk for developing myocardial injury after noncardiac surgery.

Abstract
Perioperative stress is associated with increased sympathetic activity that leads to increases in heart rate and blood pressure, which are associated with the development of perioperative myocardial ischemia. In healthy volunteers, it was shown that the administration of supplemental oxygen attenuated sympathetic nerve activity and subsequently led to lower plasma catecholamine concentrations. We therefore tested the hypothesis that perioperative supplemental oxygen attenuates sympathetic nerve in patients at risk for cardiovascular complications undergoing major abdominal surgery. We randomly assigned 81 patients to receive either 80% or 30% inspired oxygen concentration throughout surgery and the first two postoperative hours. We assessed noradrenaline, adrenaline, and dopamine plasma concentrations before the induction of anesthesia, two hours after surgery and on the third postoperative day. There was no significant difference in postoperative noradrenaline (effect estimated: −41.5 ng·L−1, 95%CI −134.3, 51.2; p = 0.38), adrenaline (effect estimated: 11.2 ng·L−1, 95%CI −7.6, 30.1; p = 0.24), and dopamine (effect estimated: −1.61 ng·L−1, 95%CI −7.2, 3.9; p = 0.57) concentrations between both groups. Based on our results, it seems unlikely that supplemental oxygen influences endogenous catecholamine release in the perioperative setting.

Abstract
OBJECTIVE To assess the feasibility of a prehabilitation program and its effects on physical performance and outcomes after major abdominal surgery. METHODS In this prospective pilot study, patients underwent prehabilitation involving three training sessions per week for 3 weeks preoperatively. The feasibility of delivering the intervention was assessed based on recruitment and adherence to the program. Its impacts on fitness (oxygen uptake (VO2)) and physical performance (Timed Up and Go Test, 6-Minute Walk Test) were evaluated. RESULTS From May 2017 to January 2020, 980 patients were identified and 44 (4.5%) were invited to participate. The main obstacles to patient recruitment were insufficient time (<3 weeks) prior to scheduled surgery (n = 276, 28%) and screening failure (n = 312, 32%). Of the 44 patients, 24 (55%) declined to participate, and 20 (23%) were included. Of these, six (30%) were not adherent to the program. Among the remaining 14 patients, VO2 at ventilatory threshold significantly increased from 9.7 to 10.9 mL/min/kg. No significant difference in physical performance was observed before and after prehabilitation. CONCLUSION Although prehabilitation seemed to have positive effects on exercise capacity, logistic and patient-related difficulties were encountered. The program is not feasible in its current form for all-comers.

Abstract
Elderly patients who undergo major abdominal surgery are being in increasing numbers. Intensive care unit (ICU) survival is critical for surgical decision-making process. Activities of daily living (ADL) are associated with clinical outcomes in the elderly. We aimed to investigate the relationship between ADL and postoperative ICU survival in elderly patients following elective major abdominal surgery.We conducted a retrospective cohort study involving patients aged ≥65 years admitted to the surgical intensive care unit (SICU) following elective major abdominal surgery. Data from all patients were extracted from the electronic medical records. The Barthel Index (BI) was used to assess the level of dependency in ADL at the time of hospital admission.ICU survivors group had higher Barthel Index (BI) scores than non-survivors group (P < .001). With the increase of BI score, postoperative ICU survival rate gradually increased. The ICU survivals in patients with BI 0-20, BI 21-40, BI 41-60, BI 61-80 and BI 81-100 were 55.7%, 67.6%, 72.4%, 83.3% and 84.2%, respectively. In logistic regression, The Barthel Index (BI) was significantly correlated with the postoperative ICU survival in elderly patients following elective major abdominal surgery (OR = 1.33, 95% CI: 1.20-1.47, P = .02). The area under the receiver operating characteristic (ROC) curve of Barthel Index in predicting postoperative ICU survival was 0.704 (95% CI, 0.638-0.771). Kaplan-Meier survival curve in BI≥30 patients and BI < 30 patients showed significantly different.Activity of daily living upon admission was associated with postoperative intensive care unit survival in elderly patients following elective major abdominal surgery. The Barthel Index(BI) ≥30 was associated with increased postoperative ICU survival. For the elderly with better functional status, they could be given more surgery opportunities. For those elderly patients BI < 30, these results provide useful information for clinicians, patients and their families to make palliative care decisions.

Abstract
Significant sleep disturbance can occur following major abdominal surgery. We aimed to evaluate the effectiveness of earplugs and eye masks in improving sleep quality and patient satisfaction, reducing nursing demands and in the incidence of delirium in patients after major abdominal surgery. We conducted a randomised controlled trial in 100 patients undergoing major abdominal surgery. We randomly allocated participants to sleep with or without earplugs and eye masks on postoperative days 1-3. The primary outcome measure was sleep quality as measured by the Richards-Campbell Sleep Questionnaire. Secondary outcomes were patient satisfaction, frequency of nursing demand and incidence of delirium measured by the Neelon and Champagne Confusion Scale. Median (IQR [range]) sleep scores were 64 (38-74 [0-100] and 60 (44-82 [18-100]) for the control and intervention groups, respectively (p = 0.310). Age and Pittsburgh Sleep Quality Index scores were found to be significant factors affecting sleep quality. There were no differences in patient satisfaction, reduction in frequency of nursing demands or incidence of delirium on postoperative days 1-3 after major abdominal surgery. The compliance rate in the intervention group was 60-65%. This study has demonstrated that the use of earplugs and eye masks did not contribute to improvements in sleep quality. Of note, sleep quality was moderate, with higher age and worse baseline sleep quality contributing to worse sleep scores. More studies are needed to investigate interventions to improve sleep quality after major abdominal surgery.

Abstract
Aim To analyse the recovery situation of patients who underwent abdominal surgery. Design A descriptive study. Method This study was conducted among 50 participants: 15 postoperative patients, 16 caregivers, 2 surgeons and 17 nurses in a tertiary hospital in Thailand. The state of patients' recovery after undergoing major abdominal surgery was analysed using Donabedian's approach. Results The findings showed that hospitals and some organizations do not have a clear policy about clinical care to help patients recover after undergoing major surgery or to prevent the risk of complications following major abdominal surgery. In addition, there were no clinical practice guidelines in use in each ward. Each ward should have a set of guidelines and procedures for assisting with patient recovery. The procedures should be based on nursing care. It is necessary to have a coordinated multidisciplinary care guideline to use with other health professionals to promote the recovery of patients.

Abstract
BACKGROUND The perioperative use of vasoactive drugs is ubiquitous in clinical anaesthesia; yet, the drugs, doses, and haemodynamic targets used are highly variable. Our objectives were to determine whether the perioperative administration of vasoactive drugs reduces mortality, morbidity, and length of stay in adult patients (aged 16 yr or older) undergoing major abdominal surgery. METHODS MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for peer-reviewed RCTs with no language or date restrictions. Studies that assessed the intraoperative use of vasoactive drugs were included. Title, abstract, and full-text screening was performed. Risk of bias for each outcome measure was conducted. We calculated the risk ratio (RR) using the Mantel-Haenszel random-effects model with corresponding 95% confidence interval (CI) for dichotomous outcomes, and mean difference using the inverse variance random-effects model with corresponding 95% CI for continuous outcomes. RESULTS Twenty-six studies (5561 participants) were included. There was no difference in mortality at the longest follow-up with an RR of 0.84 (95% CI: 0.63-1.12; P=0.23). The intervention significantly reduced the number of patients with one or more postoperative complications; RR: 0.76 (95% CI: 0.66-0.88; P=0.0002). Hospital length of stay was reduced by 0.91 days in the intervention group. CONCLUSIONS This review is limited by the quality and sample size of individual studies, and the heterogeneity of the settings, interventions, and outcome measures. Perioperative administration of vasoactive drugs may reduce postoperative complications and hospital length of stay in adult patients having major abdominal surgery.

Abstract
This proof-of-concept study aimed to evaluate a novel method of flow cytometry-based quantification of neutrophil extracellular traps (NETs) in septic shock patients and to identify possible interactions between the number of free-circulating NETs and alterations of the coagulatory system. Patients suffering from septic shock, a matched control group (CTRL), and patients suffering from systemic inflammation after cardiac (CABG) or major abdominal surgery (MAS) were enrolled in this prospective proof-of-concept study. Compared to the matched controls, free-circulating NETs were significantly elevated in septic shock and postsurgical patients (data are presented in median (IQR)); septic shock: (2.7 (1.9-3.9); CABG: 2.7 (2.1-3.7); MAS: 2.7 (2.1-3.9); CTRL: 1.6 (1-2); CTRL vs. septic shock: p = 0.001; CTRL vs. CABG: p < 0.001; CTRL vs. MAS: p < 0.001). NETs correlated positively with FIBTEM mean clot firmness (MCF) in septic shock patients (r = 0.37, p < 0.01) while they correlated negatively in surgical patients (CABG: r = -0.28, p < 0.01; MAS: r = -0.25, p = 0.03). Flow-cytometric quantification of NETs showed a significant increase in free-circulating NETs under inflammatory conditions. Furthermore, this study hints to an association of the number of NETs with hypercoagulation in septic shock patients and hypocoagulation in surgery-induced inflammation.

Abstract
The dysregulation of inflammatory response to surgical injury affects outcomes. Alarmins, the earliest bioactive substances from damaged cells, play a crucial role in initiating the inflammation. We analyzed serum levels of alarmins (S100A8, S100A12, high mobility group box, and heat shock protein 70) after major abdominal surgery (MAS) in surgical (S) (n = 82) and nonsurgical (NS) groups (n = 35). The main objective was determining a role of selected alarmins in host response to MAS. The secondary objectives were (i) evaluation of the relationship among alarmins and selected biomarkers (C-reactive protein, interleukin-6), (ii) influence of the place of gastrointestinal resection, and (iii) role of alarmins in MAS for cancer. Except for HMGB1, the levels of all alarmins were higher in the S group compared with the NS group. In the S group, positive correlations were found between S100A8 and both IL-6 and CRP. Additionally, the S100A8 level was higher (p < 0.01) in patients who underwent upper gastrointestinal tract (GIT) surgery compared to middle and lower GIT resections. Alarmins levels did not differ between cancer and noncancer patients. MAS is able to elicit increase in alarmin levels. S100A8 can be considered a potential biomarker of surgical injury, especially in the upper part of the GIT.

Abstract
INTRODUCTION Preoperative anemia and old age are independent risk factors for perioperative morbidity and mortality. However, despite the high prevalence of anemia in elderly surgical patients, there is limited understanding of the impact of anemia on postoperative complications and postdischarge quality of life in the elderly. This study aims to investigate how anemia impacts elderly patients undergoing major abdominal surgery in terms of perioperative morbidity, mortality and quality of life for 6 months postoperatively. METHODS AND ANALYSIS We will conduct a prospective observational study over 12 months of 382 consecutive patients above 65 years old, who are undergoing elective major abdominal surgery in Singapore General Hospital (SGH), a tertiary public hospital. Baseline clinical assessment including full blood count and iron studies will be done within 1 month before surgery. Our primary outcome is presence of morbidity at fifth postoperative day (POD) as defined by the postoperative morbidity survey (POMS). Secondary outcomes will include 30-day trend of POMS complications, morbidity defined by Clavien Dindo Classification system (CDC) and Comprehensive Complication Index (CCI), 6-month mortality, blood transfusion requirements, days alive out of hospital (DaOH), length of index hospital stay, 6-month readmission rates and Health Related Quality of Life (HRQoL). HRQoL will be assessed using EuroQol five-dimensional instrument (EQ-5D) scores at preoperative consult and at 1, 3, and 6 months. ETHICS AND DISSEMINATION The SingHealth Centralised Institutional Review Board (CIRB Ref: 2017/2640) approved this study and consent will be obtained from all participants. This study is funded by the National Medical Research Council, Singapore (HNIG16Dec003) and the findings will be published in peer-reviewed journals and presented at academic conferences. Deidentified data will be made available from Dryad Repository upon publication of the results.

Abstract
Background Major abdominal surgery (MAS) is associated with increased morbidity and mortality. The main objective of our study was to evaluate the predictive value of heart-rate variability (HRV) concerning development of postoperative complications in patients undergoing MAS. The secondary objectives were to identify the relationship of HRV and use of vasoactive drugs during anesthesia, intensive care unit length of stay (ICU-LOS), and hospital length of stay (H-LOS). Patients and methods Sixty-five patients scheduled for elective MAS were enrolled in a prospective, single-center, observational study. HRV was measured by spectral analysis (SA) preoperatively during orthostatic load. Patients were divided according to cardiac autonomic reactivity (CAR; n=23) and non-cardiac autonomic reactivity (NCAR; n=30). Results The final analysis included 53 patients. No significant difference was observed between the two groups regarding type of surgery, use of minimally invasive techniques or epidural catheter, duration of surgery and anesthesia, or the amount of fluid administered intraoperatively. The NCAR group had significantly greater intraoperative blood loss than the CAR group (541.7±541.9 mL vs 269.6±174.3 mL, p<0.05). In the NCAR group, vasoactive drugs were used during anesthesia more frequently (n=21 vs n=4; p<0.001), and more patients had at least one postoperative complication compared to the CAR group (n=19 vs n=4; p<0.01). Furthermore, the NCAR group had more serious complications (Clavien–Dindo ≥ Grade III n=6 vs n=0; p<0.05) and a greater number of complications than the CAR group (n=57 vs n=5; p<0.001). Significant differences were found for two specific subgroups of complications: hypotension requiring vasoactive drugs (NCAR: n=10 vs CAR: n=0; p<0.01) and ileus (NCAR: n=11 vs CAR: n=2; p<0.05). Moreover, significant differences were found in the ICU-LOS (NCAR: 5.7±3.5 days vs CAR: 2.6±0.7 days; p<0.0001) and H-LOS (NCAR: 12.2±5.6 days vs CAR: 7.2±1.7 days; p<0.0001). Conclusion Preoperative HRV assessment during orthostatic load is objective and useful for identifying patients with low autonomic physiological reserves and high risk of poor post-operative course.

Abstract
BACKGROUND Fast-track (FT) postoperative protocol in oncological patients after major abdominal surgery reduces complications and length of postoperative stay compared to the conventional (CON) protocol. However, stress and pain responses have not been compared between the two protocols. OBJECTIVES To compare stress, pain, and related neuropeptidic responses (adrenocorticotropic hormone [ACTH], cortisol, and neuropeptide Y [NPY]) between FT and CON protocols. METHOD A clinical trial with repeated measurements was conducted (May 2012 to May 2014) with a sample of 63 hepatectomized or pancreatectomized patients randomized into two groups: FT ( n = 29) or CON ( n = 34). Demographic and clinical data were collected, and pain (Visual Analog Scale [VAS] and Behavioral Pain Scale [BPS]) and stress responses (3 self-report questions) assessed. NPY, ACTH, and cortisol plasma levels were measured at T1 = day of admission, T2 = day of surgery, and T3 = prior to discharge. RESULTS ACTHT1 and ACTHT2 levels were positively correlated with self-reported stress levels (ρ = .43 and ρ = .45, respectively, p < .05) in the FT group. NPY levels in the FT group were higher than those in the CON group at all time points ( p ≤ .004); this difference remained significant after adjusting for T1 levels through analysis of covariance for age, gender, and body mass index ( F = .003, F = .149, F = .015, respectively, p > .05). CONCLUSIONS Neuropeptidic levels were higher in the FT group. Future research should evaluate this association further, as these biomarkers might serve as objective indicators of postoperative pain and stress.

Abstract
PURPOSE Tissue injury causing immune response is an integral part of surgical procedure. Evaluation of the degree of surgical trauma could help to improve postoperative management and determine the clinical outcomes. MATERIALS AND METHODS We analyzed serum levels of alarmins, including S100A5, S100A6, S100A8, S100A9, S100A11, and S100A12; high-mobility group box 1; and heat-shock protein 70, after elective major abdominal surgery (n = 82). Blood samples were collected for three consecutive days after surgery. The goals were to evaluate the relationships among the serum levels of alarmins and selected surgical characteristics and to test potential of alarmins to predict the clinical outcomes. RESULTS Significant, positive correlations were found for high-mobility group box 1 with the length of surgery, blood loss, and intraoperative fluid intake for all three days of blood sampling. The protein S100A8 serum levels showed positive correlations with intensive care unit length of stay, 28-day and in-hospital mortality. The protein S100A12 serum levels had significant, positive correlations with intensive care unit length of stay, 28-day mortality, and in-hospital mortality. We did not find significant differences in alarmin levels between cancer and noncancer subjects. CONCLUSION The high-mobility group box 1 serum levels reflect the degree of surgical injury, whereas proteins S100A8 and S100A12 might be considered good predictors of major abdominal surgery morbidity and mortality.

Abstract
BACKGROUND Acute kidney injury is a common complication after major surgery. In this study, we investigated whether an algorithm-guided goal-directed haemodynamic therapy (GDT) can improve renal outcome compared to good standard clinical care. METHODS A total of 180 patients undergoing major abdominal surgery were prospectively and randomly assigned to one of two groups: in the GDT group, patients were treated with a GDT algorithm using transpulmonary thermodilution while standard care was applied to the control patients. Change in creatinine was studied as the primary end point, postoperative complications as well as 1-year mortality as secondary outcomes. Haemodynamics in GDT and control patients were compared calculating goal-achievement rates. RESULTS Postoperative change in creatinine (18 ± 39 μmol/l (control) vs. 16 ± 42 μmol/l (GDT); mean difference (95 % confidence interval) 1.6 μmol/l (-10 to 13 μmol/l)) was comparable between the GDT and the control group. Postoperative complications and mortality during hospital stay and after 1 year were not influenced by the use of a GDT algorithm. Achievement rates of haemodynamic goals were not higher in the GDT group compared to the already high (>80 %) rates in the control group. Multivariate regression analysis revealed intraoperative hypotension (MAP < 70 mmHg) and postoperative hypovolaemia (GEDI < 640 ml/m(2)) as risk factors for postoperative renal impairment. CONCLUSIONS In this study, GDT was not superior to standard clinical care in order to avoid renal failure after major abdominal surgery. The reason for this finding is most likely the high achievement rate of haemodynamic goals in the control group, which cannot be improved by the GDT algorithm.

OBJECTIVES To identify factors associated with mortality in older adults 30, 180, and 365 days after emergency major abdominal surgery. DESIGN A retrospective study linked to Medicare claims from 2000 to 2010. SETTING Health and Retirement Study (HRS). PARTICIPANTS Medicare beneficiaries aged 65.5 enrolled in the HRS from 2000 to 2010 with at least one urgent or emergency major abdominal surgery and a core interview from the HRS within 3 years before surgery. MEASUREMENTS Survival analysis was used to describe all-cause mortality 30, 180, and 365 days after surgery. Complementary log-log regression was used to identify participant characteristics and postoperative events associated with poorer survival. RESULTS Four hundred individuals had one of the urgent or emergency surgeries of interest, 24% of whom were aged 85 and older, 50% had coronary artery disease, 48% had cancer, 33% had congestive heart failure, and 37% experienced a postoperative complication. Postoperative mortality was 20% at 30 days, 31% at 180 days, and 34% at 365 days. Of those aged 85 and older, 50% were dead 1 year after surgery. After multivariate adjustment including postoperative complications, dementia (hazard ratio (HR) = 2.02, 95% confidence interval (CI) = 1.24-3.31), hospitalization within 6 months before surgery (HR = 1.63, 95% CI = 1.12-2.28), and complications (HR = 3.45, 95% CI = 2.32-5.13) were independently associated with worse 1-year survival. CONCLUSION Overall mortality is high in many older adults up to 1 year after undergoing emergency major abdominal surgery. The occurrence of a complication is the clinical factor most strongly associated with worse survival.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a serious complication that arises after major abdominal surgery. VTE poses risks of negative outcomes and health care burden. The literature on the cost of VTE in Japanese surgical patients, however, is scarce. OBJECTIVE This study was conducted to investigate the economic consequences of VTE in Japanese patients with major abdominal surgery, using a hospital claims database. METHODS This is a retrospective, matched cohort study. Patients who had a VTE event up to 90 days after their first major abdominal surgery and initiated warfarin or heparin within 1 day of VTE diagnosis with continued treatment for more than 4 weeks were matched with controls for surgery type, hospital, and date of surgery ± 6 months in a 1:2 scheme. The primary outcome was 90-day costs associated with major abdominal surgery. The secondary outcomes were 6-month total costs, average length of initial inpatient stay, and cost of initial inpatient stay. RESULTS The 90-day cumulative incidence of VTE was 4.89%. The development of a VTE event in patients undergoing major abdominal surgery resulted in a 1.5-fold increase in the length of hospitalization and a 2.8-fold increase in total costs 90 days after the surgery. Total costs further increased to 3.4-fold at 6 months. Overall, costs incurred in patients with VTE are on average much higher than in patients without VTE throughout 6-month postsurgery. CONCLUSIONS The preventive care for VTE using more effective prophylactic treatment is recommended to reduce the economic burden associated with major abdominal surgery.
