Association between use of enhanced recovery after surgery protocol and postoperative complications in colorectal surgery: the postoperative outcomes within enhanced recovery after surgery protocol (power) study

Importance: enhanced Recovery After Surgery (ERAS) care has been reported to be associated with improvements in outcomes after colorectal surgery compared with traditional care. Objective: to determine the association between ERAS protocols and outcomes in patients undergoing elective colorectal surgery. Design, setting, and participants: the Postoperative Outcomes Within Enhanced Recovery After Surgery Protocol (POWER) Study is a multicenter, prospective cohort study of 2084 consecutive adults scheduled for elective colorectal surgery who received or did not receive care in a self-declared ERAS center. Patients were recruited from 80 Spanish centers between September 15 and December 15, 2017. All patients included in this analysis had 1 month of follow-up. Exposures: colorectal surgery and perioperative management were the exposures. Twenty-two individual ERAS items were assessed in all patients, regardless of whether they were included in an established ERAS protocol. Main outcomes and measures: the primary study outcome was moderate to severe postoperative complications within 30 days after surgery. Secondary outcomes included ERAS adherence, mortality, readmissions, reoperation rates, and hospital length of stay. Results: between September 15 and December 15, 2017, 2084 patients were included in the study. Of these, 1286 individuals (61.7%) were men; mean age was 68 years (interquartile range [IQR], 59-77). A total of 879 patients (42.2%) presented with postoperative complications and 566 patients (27.2%) developed moderate to severe complications. The number of patients with moderate or severe complications was lower in the ERAS group (25.2% vs 30.3%; odds ratio [OR], 0.77; 95% CI, 0.63-0.94; P¿=¿.01). The overall rate of adherence to the ERAS protocol was 63.6% (IQR, 54.5%-77.3%), and the rate for patients from hospitals self-declared as ERAS was 72.7% (IQR, 59.1%-81.8%) vs non-ERAS institutions, which was 59.1% (IQR, 50.0%-63.6%; P¿<¿.001). Adherence quartiles among patients receiving the highest and lowest ERAS components showed that the patients with the highest adherence rates had fewer moderate to severe complications (OR, 0.34; 95% CI, 0.25-0.46; P¿<¿.001), overall complications (OR, 0.33; 95% CI, 0.26-0.43; P¿<¿.001), and mortality (OR, 0.27; 95% CI, 0.07-0.97; P¿=¿.06) compared with those who had the lowest adherence rates. Conclusions and relevance: an increase in ERAS adherence appears to be associated with a decrease in postoperative complications

Surgical treatment for colorectal cancer: Analysis of the influence of an enhanced recovery programme on long-term oncological outcomes-a study protocol for a prospective, multicentre, observational cohort study

Introduction The evidence currently available from enhanced recovery after surgery (ERAS) programmes concerns their benefits in the immediate postoperative period, but there is still very little evidence as to whether their correct implementation benefits patients in the long term. The working hypothesis here is that, due to the lower response to surgical aggression and lower rates of postoperative complications, ERAS protocols can reduce colorectal cancer-related mortality. The main objective of this study is to analyse the impact of an ERAS programme for colorectal cancer on 5-year survival. As secondary objectives, we propose to analyse the weight of each of the predefined items in the oncological results as well as the quality of life. Methods and analysis A multicentre prospective cohort study was conducted in patients older than 18 years of age who are scheduled to undergo surgery for colorectal cancer. The study involved 12 hospitals with an implemented enhanced recovery protocol according to the guidelines published by the Spanish National Health Service. The intervention group includes patients with a minimum implementation level of 70%, and the control group includes those who fail to reach this level. Compliance will be studied using 18 key performance indicators, and the results will be analysed using cancer survival indicators, including overall survival, cancer-specific survival and relapse-free survival. The time to recurrence, perioperative morbidity and mortality, hospital stay and quality of life will also be studied, the latter using the validated EuroQol Five questionnaire. The propensity index method will be used to create comparable treatment and control groups, and a multivariate regression will be used to study each variable. The Kaplan-Meier estimator will be used to estimate survival and the log-rank test to make comparisons. A p value of less than 0.05 (two-tailed) will be considered to be significant. Ethics and dissemination Ethical approval for this study was obtained from the Aragon Ethical Committee (C.P.-C.I. PI20/086) on 4 March 2020. The findings of this study will be submitted to peer-reviewed journals (BMJ Open, JAMA Surgery, Annals of Surgery, British Journal of Surgery). Abstracts will be submitted to relevant national and international meetings.The present research study was awarded a Ministerio de Ciencia e Innovación health research project grant (PI19/00291) from the Carlos III Institute of the Spanish National Health Service as part of the 2019 call for Strategic Action in Health

Ibuprofeno intravenoso: Experiencia clínica en el tratamiento del dolor postoperatorio

About 30 % of surgical patients report high or extreme intensity postoperative pain as their main concern, which is even more relevant than satisfactory surgery results. NSAIDs are the most commonly prescribed drugs worldwide for the treatment of acute and chronic pain. Ibuprofen is widely used in prevention and treatment of pain. Recently, intravenous ibuprofen has been approved by the FDA (www.accessdata.fda.gov) for the management of mild-moderate pain and management of moderate-severe pain complementary to opioid analgesia. Additionally, has been approved for fever reduction. Given its potential as adjuvant therapy in multimodal analgesia, a review of the perioperative use of intravenous ibuprofen was conducted by analyzing literature available in English and Spanish in PubMed and Ovid MEDLINE through December 2015. The review included pharmacokinetic and pharmacodynamic data from patients of different ages as well as clinical studies where the use of opioids was quantified in the postoperative period and the synergy between these two types of drugs was analyzed. Intravenous ibuprofen offers advantages over oral presentation and is an alternative to the limited availability of intravenous NSAIDs as part of multimodal perioperative analgesia.El dolor postoperatorio de intensidad alta o extrema tiene una incidencia publicada cercana al 30 % de los pacientes quirúrgicos, siendo su principal preocupación, incluso más relevante que los resultados satisfactorios o no que pudiera tener el procedimiento en la resolución de su enfermedad. Los AINE son los fármacos más prescritos en el mundo para el tratamiento del dolor agudo y crónico de diferentes causas. El ibuprofeno es un analgésico ampliamente utilizado en la prevención y tratamiento del dolor. Recientemente, su forma intravenosa ha sido aprobada por la FDA (www.accessdata.fda.gov) para el tratamiento del dolor leve a moderado y moderado a severo complementario a la analgesia opioide. Adicionalmente, ha sido aprobado para la reducción de la fiebre. Dado su potencial como adyuvante en la analgesia multimodal, se realizó una revisión acerca del uso perioperatorio del ibuprofeno intravenoso, analizando la literatura disponible en inglés y español en PubMed y Ovid MEDLINE hasta diciembre 2015. Se incluyeron datos farmacocinéticos y farmacodinámicos provenientes de pacientes de diferentes edades, así como estudios clínicos, incluyendo aquellos en los que se cuantificó el uso de opioides en el periodo postoperatorio, analizando la sinergia entre ambos tipos de analgésicos. El ibuprofeno intravenoso ofrece ventajas sobre la presentación oral, siendo una alternativa a la limitada disponibilidad de AINE endovenosos como parte de la analgesia multimodal perioperatoria

Intraoperative goal directed hemodynamic therapy in noncardiac surgery: a systematic review and meta-analysis

Abstract Background: The goal directed hemodynamic therapy is an approach focused on the use of cardiac output and related parameters as end-points for fluids and drugs to optimize tissue perfusion and oxygen delivery. Primary aim: To determine the effects of intraoperative goal directed hemodynamic therapy on postoperative complications rates. Methods: A meta-analysis was carried out of the effects of goal directed hemodynamic therapy in adult noncardiac surgery on postoperative complications and mortality using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. A systematic search was performed in Medline PubMed, Embase, and the Cochrane Library (last update, October 2014). Inclusion criteria were randomized clinical trials in which intraoperative goal directed hemodynamic therapy was compared to conventional fluid management in noncardiac surgery. Exclusion criteria were trauma and pediatric surgery studies and that using pulmonary artery catheter. End-points were postoperative complications (primary) and mortality (secondary). Those studies that fulfilled the entry criteria were examined in full and subjected to quantifiable analysis, predefined subgroup analysis (stratified by type of monitor, therapy, and hemodynamic goal), and predefined sensitivity analysis. Results: 51 RCTs were initially identified, 24 fulfilling the inclusion criteria. 5 randomized clinical trials were added by manual search, resulting in 29 randomized clinical trials in the final analysis, including 2654 patients. A significant reduction in complications for goal directed hemodynamic therapy was observed (RR: 0.70, 95% CI: 0.62-0.79, p < 0.001). No significant decrease in mortality was achieved (RR: 0.76, 95% CI: 0.45-1.28, p = 0.30). Quality sensitive analyses confirmed the main overall results. Conclusions: Intraoperative goal directed hemodynamic therapy with minimally invasive monitoring decreases postoperative complications in noncardiac surgery, although it was not able to show a significant decrease in mortality rate

Perioperative Use of Clevidipine: A Systematic Review and Meta-Analysis

<div><p>Background</p><p>Clevidipine is an ultrashort-acting drug for rapid reduction of blood pressure by selectively acting on the L-type Ca2+ channels on arteriolar smooth muscle. The drug’s ultrashort action in reducing the blood pressure is due to its rapid hydrolysis by blood and extravascular tissue esterases, which does not depend on hepato-renal metabolism and excretion. An analysis of the perioperative management of blood pressure should be considered to compare with other intravenous antihypertensive agents.</p><p>Methods</p><p>Analyses of the available evidence in randomized clinical trials following the PRISMA methodology as well as clinical significance according to the GRADE system were conducted. Placebo versus other antihypertensive drugs studies were included. Statistical assessments were done using the X2 and I2 tests.</p><p>Results</p><p>Clevidipine was more effective in maintaining the blood pressure within pre-specified ranges compared with other antihypertensive drugs (MD, -17.87 CI 95%: -29.02 to -6.72; p = 0.02). The use of Clevidipine versus placebo and rescue antihypertensive intravenous drug showed a clear reduction in rates of treatment failure (RR 0.10; IC 95%; 0.05–0.18; p <0.0001). There was no difference in the incidence of adverse events compared with placebo (RR 1.47; 95% CI 0.89 to 2.43, p = 0.14) and with other antihypertensive drugs (RR 0.78, 95% CI 0.45 to 1.35; p = 0.37). In addition, there was no difference in the incidence of atrial fibrillation (AF) between clevidipine and control groups (RR 1.09, IC del 95%: 0.65 a 1.83; p = 0.73).</p><p>Conclusions</p><p>Clevidipine is an ultrafast-acting drug that is highly effective for management of perioperative arterial hypertension. It is devoid of adverse effects associated with the use of other IV antihypertensives. Its favorable pharmacodynamic and pharmacokinetic properties make clevidipine the drug of choice for the management of acute perioperative hypertension. It is important to emphasize the need for further studies with a larger number of patients to confirm these findings and increase the degree of evidence.</p></div
