Background & aims: Malnutrition has been recognized as a major risk factor for adverse postoperative outcomes. The ESPEN Symposium on perioperative nutrition was held in Nottingham, UK, on 14e15 October 2018 and the aims of this document were to highlight the scientific basis for the nutritional and metabolic management of surgical patients. Methods: This paper represents the opinion of experts in this multidisciplinary field and those of a patient and caregiver, based on current evidence. It highlights the current state of the art. Results: Surgical patients may present with varying degrees of malnutrition, sarcopenia, cachexia, obesity and myosteatosis. Preoperative optimization can help improve outcomes. Perioperative fluid therapy should aim at keeping the patient in as near zero fluid and electrolyte balance as possible. Similarly, glycemic control is especially important in those patients with poorly controlled diabetes, with a stepwise increase in the risk of infectious complications and mortality per increasing HbA1c. Immobilization can induce a decline in basal energy expenditure, reduced insulin sensitivity, anabolic resistance to protein nutrition and muscle strength, all of which impair clinical outcomes. There is a role for pharmaconutrition, pre-, pro-and syn-biotics, with the evidence being stronger in those undergoing surgery for gastrointestinal cancer.
Objectives:To compare the effects of intraoperative goal-directed fluid therapy (GDFT) with conventional fluid therapy, and determine whether there was a difference in outcome between studies that did and did not use Enhanced Recovery After Surgery (ERAS) protocols.Methods:Meta-analysis of randomized controlled trials of adult patients undergoing elective major abdominal surgery comparing intraoperative GDFT versus conventional fluid therapy. The outcome measures were postoperative morbidity, length of stay, gastrointestinal function and 30-day mortality.Results:A total of 23 studies were included with 2099 patients: 1040 who underwent GDFT and 1059 who received conventional fluid therapy. GDFT was associated with a significant reduction in morbidity (risk ratio [RR] 0.76, 95% confidence interval [CI] 0.66–0.89, P = 0.0007), hospital length of stay (LOS; mean difference −1.55 days, 95% CI −2.73 to −0.36, P = 0.01), intensive care LOS (mean difference −0.63 days, 95% CI −1.18 to −0.09, P = 0.02), and time to passage of feces (mean difference −0.90 days, 95% CI −1.48 to −0.32 days, P = 0.002). However, no difference was seen in mortality, return of flatus, or risk of paralytic ileus. If patients were managed in an ERAS pathway, the only significant reductions were in intensive care LOS (mean difference −0.63 days, 95% CI −0.94 to −0.32, P < 0.0001) and time to passage of feces (mean difference −1.09 days, 95% CI −2.03 to −0.15, P = 0.02). If managed in a traditional care setting, a significant reduction was seen in both overall morbidity (RR 0.69, 95% CI 0.57 to −0.84, P = 0.0002) and total hospital LOS (mean difference −2.14, 95% CI −4.15 to −0.13, P = 0.04).Conclusions:GDFT may not be of benefit to all elective patients undergoing major abdominal surgery, particularly those managed in an ERAS setting.
BACKGROUND There has recently been increasing interest in the use of peri-operative intravenous lidocaine (IVL) due to its analgesic, anti-inflammatory and opioid-sparing effects. However, these potential benefits are not well established in elective colorectal surgery. OBJECTIVES To examine the effect of peri-operative IVL infusion on postoperative outcome in patients undergoing elective colorectal surgery. DESIGN A meta-analysis of randomised controlled trials (RCTs) comparing peri-operative IVL with placebo infusion in elective colorectal surgery. The primary outcome measure was postoperative pain scores up to 48 h. The secondary outcome measures included time to return of gastrointestinal function, postoperative morphine requirement, anastomotic leak, local anaesthetic toxicity and hospital length of stay. DATA SOURCES PubMed, Scopus and the Cochrane Library databases were searched on 5 November 2018. ELIGIBILITY CRITERIA Studies were included if they were RCTs evaluating the role of peri-operative IVL vs. placebo in adult patients undergoing elective colorectal surgery. Exclusion criteria were paediatric patients, noncolorectal or emergency procedures, non-RCT methodology or lack of relevant outcome measures. RESULTS A total of 10 studies were included (n = 508 patients; 265 who had undergone IVL infusion, 243 who had undergone placebo infusion). IVL infusion was associated with a significant reduction in time to defecation (mean difference −12.06 h, 95% CI −17.83 to −6.29, I 2 = 93%, P = 0.0001), hospital length of stay (mean difference −0.76 days, 95% CI −1.32 to −0.19, I 2 = 45%, P = 0.009) and postoperative pain scores at early time points, although this difference does not meet the threshold for a clinically relevant difference. There was no difference in time to pass flatus (mean difference −5.33 h, 95% CI −11.53 to 0.88, I 2 = 90%, P = 0.09), nor in rates of surgical site infection or anastomotic leakage. CONCLUSION This meta-analysis provides some support for the administration of peri-operative IVL infusion in elective colorectal surgery. However, further evidence is necessary to fully elucidate its potential benefits in light of the high levels of study heterogeneity and mixed quality of methodology.
Summary Background and aims Computed tomography (CT)-based measurement of skeletal muscle cross-sectional area (CSA) and Hounsfield unit (HU) radiodensity are used to assess the presence of sarcopenia and myosteatosis, respectively. The validated CT-based technique involves analysis of skeletal muscle at the third lumbar vertebral (L3) level. Recently there has been increasing interest in the use of psoas muscle alone as a sentinel. However, this technique has not been extensively investigated or compared with the previous validated standard approach. Methods Portovenous phase CT images at the L3 level were identified retrospectively from a single institution in 150 patients who had non-emergency scans and were analysed by a single assessor using SliceOmatic software v5.0 (TomoVision, Canada). Manual segmentation based upon validated HU thresholds for skeletal muscle density was performed for all skeletal muscle, as well as the individual muscle groups. The muscle CSA and mean radiodensity of each group were compared against the whole L3 slice values. Results When compared with whole L3 slice CSA, anterior abdominal wall CSA had the strongest correlation (r = 0.9315, p < 0.0001) followed by paravertebral (r = 0.8948, p < 0.0001), then psoas muscle (r = 0.7041, p < 0.0001). The mean ± SD density of the psoas muscle (42 ± 8.4 HU) was significantly higher than the whole slice radiodensity (32.3 ± 9.5 HU, p < 0.0001), with paravertebral radiodensity being a more accurate estimation (34.5 ± 10.8 HU). There was a significant difference in the prevalence of myosteatosis when the density measured from the psoas was compared with that of the whole L3 skeletal muscle (27.7% vs. 66.0%, p < 0.0001). Conclusion Whole L3 slice CSA correlated positively with psoas muscle CSA but was subject to wide variability in results. Psoas muscle radiodensity was significantly greater than whole L3 slice density and resulted in underestimation of the prevalence of myosteatosis. Given the lack of equivalence from individual muscle groups, we recommend that further work be undertaken to investigate which muscle group, or indeed whether the gold standard of whole L3 skeletal muscle, provides the best correlation with clinical outcomes.
Background: The COVID-19 pandemic has changed family functioning and increased parenting demands, leading to increased risk for poor psychosocial outcomes. Emerging evidence underscores the significant impact the pandemic has had on maternal mental health concerns. In contrast, paternal mental health has yet to be described. The current study describes the prevalence of depression and anxiety in fathers of young children as well as associated risk and protective factors.Methods: As part of the Parenting during the Pandemic study, fathers (N = 70) of children age 0-8 years old self-reported on mental health symptoms and additional concerns, while mothers (N = 236) provided a partner-report of father perinatal depression.Results:. Clinically significant depression (37.1%) and anxiety (22.9%) were prevalent in fathers. Partner reported perinatal depression was prevalent in 61.9% of fathers. Higher financial strain and previous mental health history were associated with increased risk of both depression andanxiety. Maternal report of paternal depression was associated with higher financial strain, greater number of children in the home, and lower maternal-reported marital quality. Limitations: The current study used cross-sectional data from an online cohort. The sample size limits the generalizability of the findings; future research should continue evaluating this important topic with larger samples.Conclusions: Compared to pre-pandemic population comparisons, paternal depression and anxiety are elevated in the context of the COVID-19 pandemic. Intervention recommendations and implications are discussed.
Background Surgeon burnout has implications for patient safety and workforce sustainability. The aim of this study was to establish the prevalence of burnout among surgeons in the UK during the COVID-19 pandemic. Methods This cross-sectional online survey was set in the UK National Health Service and involved 601 surgeons across the UK of all specialities and grades. Participants completed the Maslach Burnout Inventory and a bespoke questionnaire. Outcome measures included emotional exhaustion, depersonalisation and low personal accomplishment, as measured by the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Results A total of 142 surgeons reported having contracted COVID-19. Burnout prevalence was particularly high in the emotional exhaustion (57%) and depersonalisation (50%) domains, while lower on the low personal accomplishment domain (15%). Burnout prevalence was unrelated to COVID-19 status; however, the greater the perceived impact of COVID-19 on work, the higher the prevalence of emotional exhaustion and depersonalisation. Degree of worry about contracting COVID-19 oneself and degree of worry about family and friends contacting COVID-19 was positively associated with prevalence on all three burnout domains. Across all three domains, burnout prevalence was exceptionally high in the Core Trainee 1–2 and Specialty Trainee 1–2 grades. Conclusions These findings highlight potential undesirable implications for patient safety arising from surgeon burnout. Moreover, there is a need for ongoing monitoring in addition to an enhanced focus on mental health self-care in surgeon training and the provision of accessible and confidential support for practising surgeons.
