RESUMEN
INTRODUCTION: ERAS (Enhanced Recovery After Surgery) protocol is now proposed as the standard of care in elective major abdominal surgery. Implementation of the ERAS protocol in emergency setting has been proposed but his economic impact has not been investigated. Aim of this study was to evaluate the cost saving of implementing ERAS in abdominal emergency surgery in a single institution. METHODS: A group of 80 consecutive patients treated by ERAS protocol for gastrointestinal emergency surgery in 2021 was compared with an analogue group of 75 consecutive patients treated by the same surgery the year before implementation of ERAS protocol. Adhesion to postoperative items, length of stay, morbidity and mortality were recorded. Cost saving analysis was performed. RESULTS: 50% Adhesion to postoperative items was reached on day 2 in the ERAS group in mean. Laparoscopic approach was 40 vs 12% in ERAS and control group respectively (p ,002). Length of stay was shorter in ERAS group by 3 days (9 vs 12 days p ,002). Morbidity and mortality rate were similar in both groups. The ERAS group had a mean cost saving of 1022,78 per patient. CONCLUSIONS: ERAS protocol implementation in the abdominal emergency setting is cost effective resulting in a significant shorter length of stay and cost saving per patient.

BACKGROUND: Neurological outcome after endovascular treatment (EVT) of acute ischemic stroke (AIS) may depend on both patient-specific and procedural factors. We hypothesized that altered systemic homeostasis might be frequent and affect outcome in these patients. The aim of this study was to analyze secondary insults during EVT of AIS and its association with outcome and anesthesiologic regimen. METHODS: This was a single-center prospective observational study on patients undergoing EVT for AIS under local anesthesia (LA), conscious sedation (CS), or general anesthesia (GA). Altered systemic parameters were recorded and quantified as secondary insults. The primary endpoint was to evaluate number, duration, and severity of secondary insults during EVT. Secondary endpoints were to analyze association of insults with modified Rankin Scale at 90 days and anesthesiologic regimen. RESULTS AND CONCLUSIONS: One hundred twenty patients were enrolled. Overall, 78% of patients experienced at least one episode of hypotension, 21% hypertension, 54% hypoxemia, 16% bradycardia, and 13% tachycardia. In patients monitored with capnometry, 70% experienced hypocapnia and 21% hypercapnia. LA was selected in 24 patients, CS in 84, and GA in 12. Hypotension insult was more frequent during GA than LA and CS (p = 0.0307), but intraprocedural blood pressure variation was higher during CS (p = 0.0357). Hypoxemia was more frequent during CS (p = 0.0087). Proportion of hypotension duration was higher in unfavorable outcome but secondary insults did not remain in the final model of multivariable analysis. Secondary insults occurred frequently during EVT for AIS but the main predictors of outcome were age, NIHSS at admission, and prompt and successful recanalization.

OBJECTIVE: The authors performed a systematic review to evaluate the effect of pharmacologic therapy on pulmonary hypertension in the perioperative setting of elective cardiac surgery (PROSPERO CRD42023321041). DESIGN: Systematic review of randomized controlled trials with a Bayesian network meta-analysis. SETTING: The authors searched biomedical databases for randomized controlled trials on the perioperative use of inodilators and pulmonary vasodilators in adult cardiac surgery, with in-hospital mortality as the primary outcome and duration of ventilation, length of stay in the intensive care unit, stage 3 acute kidney injury, cardiogenic shock requiring mechanical support, and change in mean pulmonary artery pressure as secondary outcomes. PARTICIPANTS: Twenty-eight studies randomizing 1,879 patients were included. INTERVENTIONS: Catecholamines and noncatecholamine inodilators, arterial pulmonary vasodilators, vasodilators, or their combination were considered eligible interventions compared with placebo or standard care. MEASUREMENTS AND MAIN RESULTS: Ten studies reported in-hospital mortality and assigned 855 patients to 12 interventions. Only inhaled prostacyclin use was supported by a statistically discernible improvement in mortality, with a number-needed-to-treat estimate of at least 3.3, but a wide credible interval (relative risk 1.26 × 10-17 - 0.7). Inhaled prostacyclin and nitric oxide were associated with a reduction in intensive care unit stay, and none of the included interventions reached a statistically evident difference compared to usual care or placebo in the other secondary clinical outcomes. CONCLUSIONS: Inhaled prostacyclin was the only pharmacologic intervention whose use is supported by a statistically discernible improvement in mortality in the perioperative cardiac surgery setting as treatment of pulmonary hypertension. However, available evidence has significant limitations, mainly the low number of events and imprecision.
RESUMEN
Background: The combination of surgery, bacterial spread-out, and artificial cardiopulmonary bypass surfaces results in a release of key inflammatory mediators leading to an overshooting systemic hyper-inflammatory condition frequently associated with compromised hemodynamics and organ dysfunction. A promising approach could be extracorporeal blood purification therapies in combination with IgM enriched immunoglobulin. This approach might perform a balanced control of both hyper and hypo-inflammatory phases as an immune-modulating intervention. Methods: We performed a retrospective observational study of patients with proven infection after cardiac surgery between January 2020 and December 2021. Patients were divided into two groups: (1) the first group (Control Group) followed a standard care approach as recommended by the Surviving Sepsis Campaign Guidelines; The second group (Active Group) underwent extracorporeal blood purification therapy (EBPT) in combination with intravenous administration of IgM enriched immunoglobulin 5 mL/kg die for at least three consecutive days, in conjunction with the standard approach (SSC Guidelines). In addition, ventriculo-arterial (V/A) coupling, Interleukin 6 (IL-6), Endotoxin Activity Assay (EAA), Procalcitonin, White Blood Cells (WBC) counts, Sequential Organ Failure Assessment (SOFA) Score and Inotropic Score were assessed in both two groups at different time points. Results: Fifty-four patients were recruited; 25 were in the Control Group, while 29 participants were in the Active Group. SOFA score significantly improved from baseline [12 (9-16)] until at T 3 [8 (3-13)] in the active group; it was associated with a median EAA reduction from 1.03 (0.39-1.20) at T 0 to 0.41 (0.2-0.9) at T 3 in the active group compared with control group 0.70 (0.50-1.00) at T 0 to 0.70 (0.50-1.00) at T 3 (p < 0.001). V/A coupling tended to be lower in patients of the active arm ranging from 1.9 (1.2-2.7) at T 0 to 0.8 (0.8-2.2) at T 3 than in those of the control arm ranging from 2.1 (1.4-2.2) at T0 to 1.75 (1.45-2.1) at T 3 (p = 0.099). The hemodynamic improvement over time was associated with evident but no significant decrease in inotropic score in the active group compared with the control group. Changes in EAA value from T 0 to T 4 were directly and significantly related (r = 0.39, p = 0.006) to those of V/A coupling. Conclusions: EBPT, in combination with IgM enriched immunoglobulin, was associated with a mitigated postoperative response of key cytokines with a significant decrease in IL-6, Procalcitonin, and EAA and was associated with improvement of clinical and metabolic parameters.

BACKGROUND: Reintubation is associated with higher risk of mortality. There is no clear evidence on the best spontaneous breathing trial (SBT) method to reduce the risk of reintubation. RESEARCH QUESTION: Are different methods of conducting SBTs in critically ill patients associated with different risk of reintubation compared with T-tube? STUDY DESIGN AND METHODS: We conducted a systematic review and Bayesian network meta-analysis of randomized controlled trials investigating the effects of different SBT methods on reintubation. We surveyed PubMed, MEDLINE, CINAHL, and Cochrane Central Register of Controlled Trials databases from inception to January 26, 2024. The surface under the cumulative ranking curve (SUCRA) was used to determine the likelihood that an intervention was ranked as the best. Pairwise comparisons were also investigated by frequentist meta-analysis. Certainty of the evidence was assessed according to the Grading of Recommendations, Assessment, Development, and Evaluations approach. RESULTS: A total of 22 randomized controlled trials were included, for a total of 6,196 patients. The network included nine nodes, with 13 direct pairwise comparisons. About 71% of the patients were allocated to T-tube and pressure support ventilation with positive end-expiratory pressure, with 2,135 and 2,101 patients, respectively. The only intervention with a significantly lower risk of reintubation compared with T-tube was high flow oxygen (HFO) (risk ratio, 0.23; 95% credibility interval, 0.09-0.51; moderate quality evidence). HFO was associated with the highest probability of being the best intervention for reducing the risk of reintubation (81.86%; SUCRA, 96.42), followed by CPAP (11.8%; SUCRA, 76.75). INTERPRETATION: HFO SBT was associated with a lower risk of reintubation in comparison with other SBT methods. The results of our analysis should be considered with caution due to the low number of studies that investigated HFO SBTs and potential clinical heterogeneity related to cointerventions. Further trials should be performed to confirm the results on larger cohorts of patients and assess specific subgroups.

RESUMEN
Pancreaticoduodenectomy is a major surgical procedure associated with various and important complications, often difficult to be managed. Pancreatic fistula is due to leakage of pancreatic juice in the abdominal cavity and is the main and most frequent complication after pancreatic surgery. The treatment of pancreatic fistula may change according to degree. Interventional radiology (IR) can offer powerful minimally invasive alternatives in managing pancreatic fistulas. We report the case of a patient affected by ampullar adenocarcinoma who underwent pancreaticoduodenectomy. Surgery was complicated by high-flow pancreatic fistula treated conservatively with CT guided percutaneous transhepatic drainage. Due to persistent leak of pancreatic fluid the abdominal effusion was drained percutaneously in the jejunal loop by Interventional radiology. KEY WORDS: Pancreatic fistula, Jejunal loop internal drainage, Radiological treatment.

Gastrointestinal Stromal Tumors (GISTs) are subepithelial lesions (SELs) that commonly develop in the gastrointestinal tract. GISTs, unlike other SELs, can exhibit malignant behavior, so differential diagnosis is critical to the decision-making process. Endoscopic ultrasound (EUS) is considered the most accurate imaging method for diagnosing and differentiating SELs in the gastrointestinal tract by assessing the lesions precisely and evaluating their malignant risk. Due to their overlapping imaging characteristics, endosonographers may have difficulty distinguishing GISTs from other SELs using conventional EUS alone, and the collection of tissue samples from these lesions may be technically challenging. Even though it appears to be less effective in the case of smaller lesions, histology is now the gold standard for achieving a final diagnosis and avoiding unnecessary and invasive treatment for benign SELs. The use of enhanced EUS modalities and elastography has improved the diagnostic ability of EUS. Furthermore, recent advancements in artificial intelligence systems that use EUS images have allowed them to distinguish GISTs from other SELs, thereby improving their diagnostic accuracy.
RESUMEN
BACKGROUND: The role of ß-blockers in the critically ill has been studied, and data on the protective effects of these drugs on critically ill patients have been repeatedly reported in the literature over the last two decades. However, consensus and guidelines by scientific societies on the use of ß-blockers in critically ill patients are still lacking. The purpose of this document is to support the clinical decision-making process regarding the use of ß-blockers in critically ill patients. The recipients of this document are physicians, nurses, healthcare personnel, and other professionals involved in the patient's care process. METHODS: The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) selected a panel of experts and asked them to define key aspects underlying the use of ß-blockers in critically ill adult patients. The methodology followed by the experts during this process was in line with principles of modified Delphi and RAND-UCLA methods. The experts developed statements and supportive rationales in the form of informative text. The overall list of statements was subjected to blind votes for consensus. RESULTS: The literature search suggests that adrenergic stress and increased heart rate in critically ill patients are associated with organ dysfunction and increased mortality. Heart rate control thus seems to be critical in the management of the critically ill patient, requiring careful clinical evaluation aimed at both the differential diagnosis to treat secondary tachycardia and the treatment of rhythm disturbance. In addition, the use of ß-blockers for the treatment of persistent tachycardia may be considered in patients with septic shock once hypovolemia has been ruled out. Intravenous application should be the preferred route of administration. CONCLUSION: ß-blockers protective effects in critically ill patients have been repeatedly reported in the literature. Their use in the acute treatment of increased heart rate requires understanding of the pathophysiology and careful differential diagnosis, as all causes of tachycardia should be ruled out and addressed first.
RESUMEN
BACKGROUND: Sepsis is caused by dysregulated immune responses due to infection and still presents high mortality rate and limited efficacious therapies, apart from antibiotics. Recent evidence suggests that very high dose proton pump inhibitors might regulate major sepsis mediators' secretion by monocytes, which might attenuate excessive host reactions and improve clinical outcomes. This effect is obtained with doses which are approximately 50 times higher than prophylactic esomeprazole single daily administration and 17 times higher than the cumulative dose of a three day prophylaxis. We aim to perform a randomized trial to investigate if high dose esomeprazole reduces organ dysfunction in patients with sepsis or septic shock. METHODS: This study, called PPI-SEPSIS, is a multicenter, randomized, double blind, placebo-controlled clinical trial on critically ill septic patients admitted to the emergency department or intensive care unit. A total of 300 patients will be randomized to receive high dose esomeprazole (80 mg bolus followed by 12 mg/h for 72 h and a second 80 mg bolus 12 h after the first one) or equivolume placebo (sodium chloride 0.9%), with 1:1 allocation. The primary endpoint of the study will be mean daily Sequential Organ Failure Assessment (SOFA) score over 10 days. Secondary outcomes will include antibiotic-free days, single organ failure severity, intensive care unit-free days at day 28, and mortality. DISCUSSION: This trial aims to test the efficacy of high dose esomeprazole to reduce acute organ dysfunction in patients with septic shock. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov with the trial identification NCT03452865 in March 2018.
RESUMEN
Myxoma is the most common benign primary tumor of the heart. Diagnosis of cardiac myxoma is difficult as it presents itself with varying nonspecific symptoms, and an echocardiography can easily diagnose it. Sometimes, it can cause cardiac syncope and thromboembolic events. A woman with a recent infection by severe acute respiratory syndrome coronavirus-2 was admitted to our hospital with respiratory symptoms: dyspnea and tachypnea; cardiac symptoms: atrial fibrillation; and neurological symptoms: syncope. Initially, she performed brain computed tomography (CT) and CT angiography value. Transthoracic echocardiogram and transesophageal echocardiogram showed an atrial mobile mass. Chest X-ray did not show any interstitial lesions. Therefore, urgent cardiac surgery was performed to remove the mass. The histological examination confirmed the presence of a cardiac myxoma. Our experience could show the importance of early diagnosis and prompt surgical treatment to prevent stroke.
RESUMEN
BACKGROUND: The appropriate timing of surgery and perioperative management of patients with previous SARS-CoV-2 infection are open issues. The purpose of this document is to support the clinical decision-making process regarding the patient with previous Sars-CoV-2 infection to undergo elective surgery. The recipients of this document are physicians, nurses, healthcare personnel, and other professionals involved in the patient's surgical process. METHODS: The Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI) selected 11 experts to reach a consensus on key aspects of this theme in adult and pediatric population. The methods of this process document were in accordance to the principles of rapid review of the scientific literature and modified Delphi method. The experts produced statements and supporting reasons in the form of an informative text. The overall list of statements was subjected to a vote in order to express the degree of consent. RESULTS: Patients should not undergo elective surgery within 7 weeks of infection unless there is the risk of a negative evolution of the disease. To mitigate the risk of postsurgical mortality, a multidisciplinary approach seemed useful in addition to the use of validated algorithms to estimate the risk of perioperative morbidity and mortality; the risk related to SARS-CoV-2 infection should be added. The risk of potential nosocomial contagion from a positive patients should also be considered when deciding to proceed with surgery. Most of the evidence came from previous SARS-CoV-2 variants, so the evidence should be considered indirect. CONCLUSION: A balanced preoperative multidisciplinary risk-benefit evaluation is needed in patients with previous infection by SARS-CoV-2 for elective surgery.
RESUMEN
BACKGROUND: Postoperative acute kidney injury (AKI) is frequent in cardiac surgery patients. Its pathophysiology is complex and involves decreased renal perfusion. Preliminary clinical evidence in critically ill patients shows that amino acids infusion increases renal blood flow and may decrease the incidence and severity of AKI. We designed a study to evaluate the effectiveness of perioperative continuous infusion of amino acids in decreasing AKI. METHODS: This is a phase III, multi-center, randomized, double-blind, placebo-controlled trial. Adults undergoing cardiac surgery with cardiopulmonary bypass (CPB) are included. Patients are randomly assigned to receive either continuous infusion of a balanced mixture of amino acids in a dose of 2 g/kg ideal body weight/day or placebo (balanced crystalloid solution) from the operating room up to start of renal replacement therapy (RRT), or ICU discharge, or 72 h after the first dose. The primary outcome is the incidence of AKI during hospital stay defined by KDIGO (Kidney Disease: Improving Global Outcomes). Secondary outcomes include the need for, and duration of, RRT, mechanical ventilation; ICU and hospital length of stay; all-cause mortality at ICU, hospital discharge, 30, 90, and 180 days after randomization; quality of life at 180 days. Data will be analyzed in 3500 patients on an intention-to-treat basis. DISCUSSION: The trial is ongoing and currently recruiting. It will be one of the first randomized controlled studies to assess the relationship between amino acids use and kidney injury in cardiac surgery. If our hypothesis is confirmed, this practice could reduce morbidity in the studied population. STUDY REGISTRATION: This trial was registered on ClinicalTrials.gov with the trial identification NCT03709264 in October 2018.

This case report describes an unusual case of a 69-year-old man who had an aortic valve replacement with the Smeloff-Cutter aortic mechanical prosthesis for aortic valve regurgitation at the age of 18 years. Echocardiography revealed a well-suited and well-functioning mechanical prosthesis. Even though the patient did not take any anticoagulant therapy or anti-platelets agent for 12 years, he was in surprisingly good health. To the best of our knowledge, this is the first time a mechanical 'ball-in-cage' valve prosthesis has lasted for such a long time without complications, although the patient has not been compliant with the anticoagulant therapy for 12 consecutive years.

Myxoma is one of the most common cardiac tumors. It is relatively straightforward to diagnose by echocardiography. Sometimes, It can causes cardiac syncope and thromboembolic events. A woman without comorbidities was admitted to our hospital with stroke symptoms: left-sided hemiplegia and dysarthria. After brain computed tomography (CT) and angio-CT value, she was initially treated with pharmacological thrombolysis. Due to persisting symptoms, cerebral angiography and thrombectomy were then performed. At the end of this procedure, the patient had a complete neurological recovery, but she developed new symptoms, such as dyspnea and orthopnea. Transthoracic echocardiogram and transesophageal echocardiogram showed an atrial mobile mass. Therefore, an urgent cardiac surgery was performed in order to remove the mass. Histological examination confirmed cardiac myxoma. Our experience could show the importance of echocardiography to early diagnosis.
RESUMEN
Rapunzel syndrome is a rare case of bowel obstruction resulting from hair ingestion (Trichobezoar). The obstruction can occur in any level of intestinal tract, but usually the stomach is primary involved. This syndrome is usually reported in patients affected by Trichotillomania or Pica syndrome, an obsessive-compulsive disorder that are characterized by an irresistible need to eat body hairs or non-digestible substances 1. When bowel obstruction occurs, it may be treated conservatively, but sometimes surgery is required. We reported two cases of Rapunzel Syndrome in two pediatric patients with different clinical presentation. Both patients were initially treated conservatively but eventually they underwent surgery. KEY WORDS: Bowel obstruction, Rapunzel syndrome, Trichobezoar.

The purpose of the study was to determine whether low-high fidelity medical simulation improves learning and long-lasting retention of pharmacology knowledge, compared to lecture alone, in undergraduate medical students. Ninety students, before a 45-minute lecture, were randomized into three groups - sham (S), low (LF), and high fidelity (HF) simulation - to participate in an interactive simulation session. To evaluate immediate and long-lasting retention, a 20-item structured questionnaire on inotropic agents was administered to 90 students before and after a 45-minute lecture, after simulation, and 3 months later. In all groups, the rate of correct answers increased after lecture, while no difference was observed between different groups (P = 0.543). After simulation, students in the HF group provided more correct answers compared to S or LF group (P > 0.001). After 3 months, a significant decrease in the number of correct answers was observed in S (P < 0.001) and LF (P < 0.001) groups, but not in the HF group (P = 0.066). Moreover, HF simulation resulted in an increased number of correct answers compared to the LF (P < 0.001) or S simulation (P < 0.001). These data suggest that advanced medical simulation teaching applied to pharmacology is associated with more effective learning and long-lasting retention compared to lecture alone.

INTRODUCTION: While anesthetics are indispensable clinical tools and generally considered safe and effective, a growing concern over the potential neurotoxicity of anesthesia or specific anesthetic agents has called into question the safety of general anesthetics, especially when administered at extremes of age. Areas covered: This article reviews and updates research findings on the safety of anesthesia and anesthetics in terms of long-term neurotoxicity, with particular focus on postoperative cognitive dysfunctions, Alzheimer's disease and dementias, developing brain, post-operative depression and autism spectrum disorder. Expert opinion: Exposure to general anesthetics is potentially harmful to the human brain, and the consequent long-term cognitive deficits should be classified as an iatrogenic pathology, and considered a public health problem. The fact that in laboratory and clinical research only certain anesthetic agents and techniques, but not others, appear to be involved, raises the problem on what is the safest and the least safe anesthetic to maximize anesthesia efficiency, avoid occurrence of adverse events, and ensure patient safety. New trends in research are moving toward the theory that neuroinflammation could be the hallmark of, or could have a pivotal role in, several neurological disorders.

Currently, the treatment of choice in urothelial tumors of the upper urinary tract is nephroureterectomy (NU) as an Open procedure (ONU), though the laparoscopic treatment is now routinely performed as a minimally invasive therapy (LNU). LNU has demonstrated oncologic safety at least equivalent to open, but some issues dealing with cancer still remain. We retrospectively analyzed data from 36 LNU performed between 2006 and 2010, compared with data of 32 ONU performed in 2002-2005 (pre-laparoscopy era). The mean follow-up was 23 months in patients undergoing LNU and 42 months for those treated with ONU. In particular, we evaluated cancer recurrence, the site of recurrence and survival rates. We had local recurrence in 3 patients (8.3%) after LNU and 2 after ONU (6.25%). 2 patients who underwent LNU (5.5%) died of metastatic disease at 9 and 12 months; 3 patients who underwent ONU (9.3%) died of metastasis at 12, 16 and 23 months, respectively. Bladder recurrence was observed in 3 patients after ONU and in 4 after LNU. The most frequent sites of cancer recurrence were: local recurrence (3 LUN, 2 ONU), 1 laparoscopic port recurrence, 3 regional lymph node recurrences (2 LNU, 1ONU), bladder recurrences (3 LNU, 4 ONU). There were no significant differences in disease recurrence and even survival rates at 1 and 3 years were not very different between the two techniques. The grade and stage of cancer affecting the incidence of metastatic disease, as well as the localization of early disease (pelvis-ureter-both) is a negative prognostic factor, rather than the surgical technique used. Therefore, there is no evidence that the control is compromised in cancer patients treated with LNU rather than with ONU.
