Abstract
Surgery under anesthesia poses a significant stress to the body, and postoperative complications occur in up to 20% of cases. An understanding of postoperative complications, including assessment of patients at risk, risk mitigation, early recognition, and evidence-based treatment, is essential to provide high-value health care. Common postoperative complications reviewed in this article include fever, cerebrovascular accident, nausea and vomiting, ileus, and urinary retention, including discussion of pathophysiology, prevention, and treatment.

Abstract
After emergency surgery for intestinal obstruction caused by colorectal cancer, postoperative ileus (POI) is more likely to occur in the early-stage oral intake. POI incited the occurrence of postoperative complications and prolongs hospital stay. Reducing the occurrence of POI will Enhance Recovery After Surgery (ERAS). AIM The aim of this study is to observe and evaluate the preventive effect of postoperative oral administration of 76% Meglumine Diatrizoate in reducing the incidence of POI and promoting intestinal absorption during the recovery of intestinal peristalsis in patients after intestinal obstruction surgery. METHODS From October 2018 to December 2021, 94 patients (47 vs 47) with intestinalobstruction were rolled. Patients with an ASA score of 4 or higher and gastrointestinal perforation with peritonitis were excluded. After 24 hours of surgery, the patients were divided into experimental group and control group disposed of with an opaque airtight envelope method, patient-side single blind. After intestinal peristalsis recovery (2.45 ± 0.62 d vs 2.60 ± 0.68 d, P > 0.05), the experimental group was given 76% Meglumine Diatrizoate 20 ml orally 9am and the control group was given 10% glucose 20 ml for three consecutive days. POI cases, the time taken to achieve full daily oral calorie and discharge days were counted. RESULTS The time required to achieve full daily oral calorie (11.04 ± 2.70 d vs 14.09 ± 3.74 d, p < 0.05), POI cases (10/47 vs 20/47, p < 0.05) and discharge days (14.00 ± 4.89 d vs 16.77 ± 5.94 d, p < 0.05) are significantly different between the two groups. CONCLUSIONS Oral 76% Meglumine Diatrizoate is safe and effective, which can reduce the occurrence of POI, promote the recovery of intestinal absorption and shorten the length of hospital stay effectively.

[PMID: 39351552 PMCID: PMC11438810 DOI: 10.4240/wjgs.v16.i9.3020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Revised: 08/13/2024] [Accepted: 08/22/2024] [Indexed: 09/18/2024] Open
Abstract
BACKGROUND Postoperative ileus (POI) is a common complication after abdominal surgery with high morbidity, which hinders patient recovery, prolongs hospitalization, and increases healthcare costs. Therefore, POI has become a global public health challenge. POI triggering is multifactorial. Autonomic and hormonal mechanisms are generally involved in POI pathogenesis. Recent studies have shown that beta adrenergic signaling of enteric glia is a POI trigger. Currently, the status quo, trends, and frontiers of global research on POI remain unclear. AIM To explore the current status, trends, and frontiers of POI research from 2011 to the present based on bibliometric analysis. METHODS Publications published on POI research from 2011 to 2023 were retrieved on June 1, 2023, from the Web of Science Core Collection. CiteSpace 6.2.R2 and VOSviewer were used to conduct bibliometric visualization. RESULTS In total, 778 POI records published from 2011 to 2023 were retrieved. Over the past few decades, the annual cumulative number of related articles has linearly increased, with China and the United States of America contributing prominently. All publications were from 59 countries and territories. China and the University of Bonn were the top contributing country and institution, respectively. Neurogastroenterology & Motility was the most prolific journal. The Journal of Gastrointestinal Surgery had the highest number of citations. Wehner Sven was the most productive author. Burst keywords (e.g., colon, prolonged ileus, acupuncture, paralytic ileus, pathophysiology, rectal cancer, gastrointestinal function, risk) and a series of reference citation bursts provided evidence for the research frontiers in recent years. CONCLUSION This study demonstrates trends in the published literature on POI and provides new insights for researchers. It emphasizes the importance of multidisciplinary cooperation in the development of this field.

Postoperative Hydration in Children Using Intermittent Boluses of Balanced Salt Solution: Results of a Randomized Control Trial. J Pediatr Surg 2024:161660. [PMID: 39181778 DOI: 10.1016/j.jpedsurg.2024.07.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Revised: 07/24/2024] [Accepted: 07/29/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND Postoperative maintenance fluids are traditionally provided via hypotonic dextrose containing fluids administered intravenously by continuous infusion. We hypothesized that scheduled weight-based boluses of balanced salt solution would be more physiologic, reduce fluid volumes, and improve patient comfort. METHODS As part of an IRB-approved randomized controlled trial (Boluses of Ringer's in Surgical Kids, BRiSK), we randomized patients aged 1-21 years undergoing elective abdominal or thoracic surgery to post-operatively receive weight-based D50.45NS+20mEq/L KCl at a continuous rate or intermittent boluses of Lactated Ringer's solution until oral liquid toleration. Patients with nephropathy, diabetes, or receiving parenteral nutrition were excluded. We analyzed electrolytes, urine output, fluid volume, and adverse events. RESULTS We enrolled and randomized 60 patients: 29 to continuous fluids and 31 to bolus fluids. One patient from the bolus group dropped out. No patients crossed over due to difficulties with application of the bolus protocol. There were no baseline differences between groups with a mean age of 12.6 ± 1.4yr and weight of 50.9 ± 7.2 kg. There were no serious adverse events or electrolyte disturbances in either group. Patients in the bolus group received significantly less total fluid than those in the continuous group (0.43 mL/kg/h vs 1.1 mL/kg/h, p < 0.001) with no difference in urine output [1.4 ± 0.2 mL/kg/h vs 1.6 ± 0.3 mL/kg/h, p = 0.211]. There were two episodes of mild hypoglycemia in the bolus group compared to seven episodes of mild hyperglycemia in the continuous group. CONCLUSIONS Administration of post-operative intravenous fluids as boluses of balanced salt solution is feasible, safe, and results in significantly less fluid administered compared to a traditional continuous protocol.

Abstract
BACKGROUND Prophylactic intraoperative drains have been shown not superior for patients underwent intestinal surgery. However, for patients with Crohn's disease (CD), this needs further exploration. METHODS In this pilot study, CD patients were randomly assigned to drain (n = 50) and no-drain (n = 50) groups. The primary endpoint was the rate of postoperative prolonged ileus (PPOI). The secondary endpoints were postoperative abdominal ascites, postoperative systemic inflammatory response syndrome (SIRS) and C-reactive protein (CRP) levels. RESULTS The incidences of PPOI and postoperative abdominal ascites were significantly lower in the drain group (12% vs 44%; 0% vs 24%, both P < .05). Postoperative SIRS incidence and CRP levels were significantly increased in the no-drain group [36% vs 10%; 54.9 vs 34.3 mg/L, both P < .05]. In multivariate analysis, prophylactic drainage was the independent protective factor for PPOI and postoperative LOS. CONCLUSIONS Prophylactic drainage may be associated with improved clinical outcomes in CD patients.

Abstract
Under physiological or pathological conditions, transient receptor potential (TRP) channel vanilloid type 1 (TRPV1) and TRP ankyrin 1 (TRPA1) possess the ability to detect a vast array of stimuli and execute diverse functions. Interestingly, increasing works have reported that activation of TRPV1 and TRPA1 could also be beneficial for ameliorating postoperative ileus (POI). Increasing research has revealed that the gastrointestinal (GI) tract is rich in TRPV1/TRPA1, which can be stimulated by capsaicin, allicin and other compounds. This activation stimulates a variety of neurotransmitters, leading to increased intestinal motility and providing protective effects against GI injury. POI is the most common emergent complication following abdominal and pelvic surgery, and is characterized by postoperative bowel dysfunction, pain, and inflammatory responses. It is noteworthy that natural herbs are gradually gaining recognition as a potential therapeutic option for POI due to the lack of effective pharmacological interventions. Therefore, the focus of this paper is on the TRPV1/TRPA1 channel, and an analysis and summary of the processes and mechanism by which natural herbs activate TRPV1/TRPA1 to enhance GI motility and relieve pain are provided, which will lay the foundation for the development of natural herb treatments for this disease.

Abstract
The 3 time periods around colic surgery (preoperative, operative, and postoperative) are all critical to successful outcomes. Although much focus is often paid to the first 2 time periods, the importance of sound clinical judgment and rational decision-making in the postoperative period cannot be overstated. This article will outline the basic principles of monitoring, fluid therapy, antimicrobial therapy, analgesia, nutrition, and other therapeutics routinely used in patients following colic surgery. Discussions of the economics of colic surgery and expectations for normal return to function will also be included.

Abstract
PURPOSE Maintenance fluids following major operations in children are typically administered with a continuous rate. We hypothesized that administering fluids as intermittent boluses is more physiologic and could limit post-operative fluid volume, thereby avoiding harmful effects of excess fluid. METHODS We retrospectively reviewed children aged 1-21 admitted after an elective major abdominal or thoracic operation from 2015 to 2021. We excluded non-elective operations and patients receiving peri-operative enteral or parenteral nutrition. We analyzed total fluid volume at 0-24, 24-48, 48-72, and 72-96 h, time to regular diet and discharge, and end-organ complications. RESULTS We identified 363 patients, of which 108 received intermittent boluses and 255 continuous fluids. Bolus group patients received significantly less fluid up to 72 h post-operatively with average rates of 0.49 mL/kg/h vs 0.86 mL/kg/h at 0-24 h (p << 0.01), 0.57 mL/kg/h vs 1.46 mL/kg/h at 24-48 h (p << 0.01), and 0.50 vs 0.92 mL/kg/h at 48-72 h (p << 0.01). Additionally, the bolus group maintained adequate urine output, tolerated a regular diet sooner (2.08 days vs 2.51 days; p = 0.0023) and averaged a shorter hospital stay (3.12 vs 4.14 days; p = 0.004). There was no difference in adverse effects between the two groups. CONCLUSION Utilizing intermittent boluses reduces the volume of maintenance fluids administered and may lead to a faster time to regular diet and discharge. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE We aim to identify the risk factors of PPOI in patients with CD and create a nomogram for prediction of PPOI for CD. METHODS Data on 462 patients who underwent partial intestinal resection for CD in Jin-ling Hospital between January 2019 and June 2021 were retrospectively collected. Univariate and multivariate analyses were performed to determine the risk factors for PPOI and we used the risk factors to create a nomogram. Then we used the Bootstrap-Concordance index and calibration diagrams to evaluate the performance of the Nomogram. Decision curve analysis was performed to evaluate clinical practicability of the model. RESULTS The incidence of PPOI was 27.7% (n of N). Course of CD ≥ 10 years, operation time ≥ 154 min, the lowest mean arterial pressure ≤ 76.2 mmHg, in-out balance per body weight ≥ 22.90 ml/kg, post-op day 1 infusion ≥ 2847 ml, post-op lowest K+ ≤ 3.75 mmol/L, and post-op day 1 procalcitonin ≥ 2.445 ng/ml were identified as the independent risk factors of PPOI in patients with CD. The nomogram we created by these risk factors presented with good discriminative ability (concordance index 0.723) and was moderately calibrated (bootstrapped concordance index 0.704). The results of decision curve analysis showed that the nomogram was clinically effective within probability thresholds in the 8 to 66% range. CONCLUSION The nomogram we developed is helpful to evaluate the risk of developing PPOI after partial intestinal resection for CD. Clinicians can take more necessary measures to prevent PPOI in CD's patients or at least minimize the incidence.

Abstract
Post-operative ileus (POI) is a frequent complication after abdominal surgery. The consequences of POI can be potentially serious such as bronchial inhalation or acute functional renal failure. Numerous advances in peri-operative management, particularly early rehabilitation, have made it possible to decrease POI. Despite this, the rate of prolonged POI ileus remains high and can be as high as 25% of patients in colorectal surgery. From a pathophysiological point of view, POI has two phases, an early neurological phase and a later inflammatory phase, to which we could add a "pharmacological" phase during which analgesic drugs, particularly opiates, play a central role. The aim of this review article is to describe the phases of the pathophysiology of POI, to analyse the pharmacological treatments currently available through published clinical trials and finally to discuss the different research areas for potential pharmacological targets.

Abstract
BACKGROUND This systematic review examines the feasibility and safety of implementing Enhanced recovery after Surgery (ERAS) protocols in children. STUDY DESIGN A systematic search of Medline, PubMed, and the Cochrane library for papers describing ERAS implementation in children between January 2000 and January 2021. The systematic review was performed according to the PRISMA statement. The meta-analysis was done using R Software (Ver 4.0.2). p value of < 0.05 was considered statistically significant. RESULTS Sixteen studies, describing a total of 1723 patients, were included in the meta-analysis. An average of 15 (range 11-16) relevant components were implemented with an overall compliance close to 84%. The time to initiate feeds and reach full enteral nutrition was reduced in ERAS group with mean difference (MD) of - 21.20 h (95% CI - 22.80, - 19.59, p < 0.01), and - 2.20 days (95% CI - 2.72, - 1.71, p < 0.01), respectively. The use of opioids for postoperative analgesia was reduced with MD of -0.86 morphine equivalents mg/kg (95% CI - 1.40, - 0.32, p < 0.01). The length of hospital stay showed a significant reduction with MD of -2.54 days (95% CI - 2.94, - 2.13, p < 0.01). There was no difference in the complication and readmission rates between the groups. CONCLUSION ERP implementation in pediatric perioperative care is a viable option in a variety of surgical settings. There is clear evidence of a decrease in hospital stay duration with no increase in complication or readmission rates. The length of hospital stay reduced in inverse proportion to the number of ERAS elements implemented. Parental satisfaction is increased by initiating enteral feeding early, minimizing catheter and drain use, and reducing opioid use.

Abstract
Fluid balance is an essential issue in critical care; however, the impact of early fluid balance on the long-term mortality in critically ill surgical patients remains unknown. This study aimed to address the impact of day 1–3 and day 4–7 fluid balance on the long-term mortality in critically ill surgical patients. We enrolled patients who were admitted to surgical intensive care units (ICUs) during 2015–2019 at a tertiary hospital in central Taiwan and retrieved date-of-death from the Taiwanese nationwide death registration profile. We used a Log-rank test and a multivariable Cox proportional hazards regression model to determine the independent mortality impact of early fluid balance. A total of 6978 patients were included for analyses (mean age: 60.9 ± 15.9 years; 63.9% of them were men). In-hospital mortality, 90-day mortality, 1-year and overall mortality was 10.3%, 15.8%, 23.8% and 31.7%, respectively. In a multivariable Cox proportional hazard regression model adjusted for relevant covariates, we found that positive cumulative day 4–7 fluid balance was independently associated with long-term mortality (aHR 1.083, 95% CI 1.062–1.105), and a similar trend was found on day 1–3 fluid balance, although to a lesser extent (aHR 1.027, 95% CI 1.011–1.043). In conclusion, the fluid balance in the first week of ICU stay, particularly day 4–7 fluid balance, may affect the long-term outcome in critically ill surgical patients.

Subtyping Hyperchloremia among Hospitalized Patients by Machine Learning Consensus Clustering. MEDICINA-LITHUANIA 2021; 57:medicina57090903. [PMID: 34577826 PMCID: PMC8465989 DOI: 10.3390/medicina57090903] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 08/26/2021] [Accepted: 08/26/2021] [Indexed: 01/20/2023]
Abstract
Background and Objectives: Despite the association between hyperchloremia and adverse outcomes, mortality risks among patients with hyperchloremia have not consistently been observed among all studies with different patient populations with hyperchloremia. The objective of this study was to characterize hyperchloremic patients at hospital admission into clusters using an unsupervised machine learning approach and to evaluate the mortality risk among these distinct clusters. Materials and Methods: We performed consensus cluster analysis based on demographic information, principal diagnoses, comorbidities, and laboratory data among 11,394 hospitalized adult patients with admission serum chloride of >108 mEq/L. We calculated the standardized mean difference of each variable to identify each cluster's key features. We assessed the association of each hyperchloremia cluster with hospital and one-year mortality. Results: There were three distinct clusters of patients with admission hyperchloremia: 3237 (28%), 4059 (36%), and 4098 (36%) patients in clusters 1 through 3, respectively. Cluster 1 was characterized by higher serum chloride but lower serum sodium, bicarbonate, hemoglobin, and albumin. Cluster 2 was characterized by younger age, lower comorbidity score, lower serum chloride, and higher estimated glomerular filtration (eGFR), hemoglobin, and albumin. Cluster 3 was characterized by older age, higher comorbidity score, higher serum sodium, potassium, and lower eGFR. Compared with cluster 2, odds ratios for hospital mortality were 3.60 (95% CI 2.33-5.56) for cluster 1, and 4.83 (95% CI 3.21-7.28) for cluster 3, whereas hazard ratios for one-year mortality were 4.49 (95% CI 3.53-5.70) for cluster 1 and 6.96 (95% CI 5.56-8.72) for cluster 3. Conclusions: Our cluster analysis identified three clinically distinct phenotypes with differing mortality risks in hospitalized patients with admission hyperchloremia.

Abstract
BACKGROUND The lymphatic system and the cardiovascular system work together to maintain body fluid homeostasis. Despite that, the lymphatic system has been relatively neglected as a potential drug target and a source of adverse effects from cardiovascular drugs. Like the heart, the lymphatic vessels undergo phasic contractions to promote lymph flow against a pressure gradient. Dysfunction or failure of the lymphatic pump results in fluid imbalance and tissue oedema. While this can due to drug effects, it is also a feature of breast cancer-associated lymphoedema, chronic venous insufficiency, congestive heart failure and acute systemic inflammation. There are currently no specific drug treatments for lymphatic pump dysfunction in clinical use despite the wealth of data from pre-clinical studies. AIM To identify (1) drugs with direct effects on lymphatic tonic and phasic contractions with potential for clinical application, and (2) drugs in current clinical use that have a positive or negative side effect on lymphatic function. METHODS We comprehensively reviewed all studies that tested the direct effect of a drug on the contractile function of lymphatic vessels. RESULTS Of the 208 drugs identified from 193 studies, about a quarter had only stimulatory effects on lymphatic tone, contraction frequency and/or contraction amplitude. Of FDA-approved drugs, there were 14 that increased lymphatic phasic contractile function. The most frequently used class of drug with inhibitory effects on lymphatic pump function were the calcium channels blockers. CONCLUSION This review highlights the opportunity for specific drug treatments of lymphatic dysfunction in various disease states and for avoiding adverse drug effects on lymphatic contractile function.

Abstract
Acute hemorrhage in small animals results from traumatic and non-traumatic causes. This review seeks to describe current understanding of the resuscitation of the acutely hemorrhaging small animal (dog and cat) veterinary patient through evaluation of pre-clinical canine models of hemorrhage and resuscitation, clinical research in dogs and cats, and selected extrapolation from human medicine. The physiologic dose and response to whole blood loss in the canine patient is repeatable both in anesthetized and awake animals and is primarily characterized clinically by increased heart rate, decreased systolic blood pressure, and increased shock index and biochemically by increased lactate and lower base excess. Previously, initial resuscitation in these patients included immediate volume support with crystalloid and/or colloid, regardless of total volume, with a target to replace lost vascular volume and bring blood pressure back to normal. Newer research now supports prioritizing hemorrhage control in conjunction with judicious crystalloid administration followed by early consideration for administration of platelets, plasma and red blood during the resuscitation phase. This approach minimizes blood loss, ameliorates coagulopathy, restores oxygen delivery and correct changes in the glycocalyx. There are many hurdles in the application of this approach in clinical veterinary medicine including the speed with which the bleeding source is controlled and the rapid availability of blood component therapy. Recommendations regarding the clinical approach to volume resuscitation in the acutely hemorrhaging veterinary patient are made based on the canine pre-clinical, veterinary clinical and human literature reviewed.

Abstract
ABSTRACT Abdominal compartment syndrome is a serious potential complication of burn injury, and carries high morbidity and mortality. Although there are generalised published guidelines on managing the condition, to date no management algorithm has yet been published tailored specifically to the burn injury patient. We set out to examine the literature on the subject in order to produce an evidence based management guideline, with the aim of improving outcomes for these patients. The guideline covers early detection and assessment of the condition as well as optimum medical, surgical and postoperative management. We believe that this guideline provides a much needed benchmark for managing burns patients with raised intra-abdominal pressure, as well as providing a template for further research and improvements in care.

Abstract
This study aimed to investigate the effect of intraoperative fluid volume on the postoperative ileus (POI) recovery period. A retrospective review of the Korean robot-assisted radical cystectomy database identified 718 patients who underwent robot-assisted radical cystectomy (RARC). Regression analyses were performed to identify the associations between the amount of intraoperative fluid administration (crystalloid/colloid/total), POI period (time to flatus/bowel movements), and length of hospital stay (LOS) after adjusting for covariates. In addition, we analyzed the risk factors for gastrointestinal complications and prolonged POI using a logistic regression model. An increasing volume of the administered crystalloid/total fluid was associated with prolonged POI (crystalloid R2 = 0.0725 and P < 0.0001; total amount R2 = 0.0812 and P < 0.0001), and the total fluid volume was positively associated with the LOS (R2 = 0.099 and P < 0.0001). The crystalloid amount was a risk factor for prolonged POI (P < 0.001; odds ratio, 1.361; 95% confidence interval, 1.133–1.641; P < 0.001). In the context of RARC, increased intravenous fluids are associated with prolonged POI and longer LOS.

Abstract
Maintenance fluid therapy is challenging in horses that cannot drink or are denied feed and water because of concerns about gastrointestinal tract function and patency. Intravenous fluid delivery to meet water needs based on current recommendations for maintenance requirements were obtained in fed horses and therefore might not apply to horses that are not being fed. This is a critical flaw because of the interdependence between intestinal tract water and extracellular water to support digestion while preserving water balance, a concept explained by the enterosystemic cycle. Because horses drink less when they are not eating and hence have lower water needs than fed horses, maintenance water requirements need to be adjusted accordingly. This article reviews this topic and identifies benefits of adjusting maintenance fluid therapy to meet lower demands from gastrointestinal function, such as reduced volumes, lower cost, avoidance of overhydration.

Abstract
Purpose: The study aimed to investigate the risk factors for postoperative ileus (POI) after small intestinal fistula excision (SIFE) in patients with diffuse extensive abdominal adhesions. Methods: From October 2010 to December 2019, we enrolled patients who underwent SIFE and had diffuse extensive abdominal adhesions. Patients were divided into the POI group and the non-POI group according to its occurrence. We then investigated and analyzed the clinical characteristics of both groups. Result: A total of 247 patients were enrolled into the study. There were 100 patients in the POI group, and 147 patients in the non-POI group. A multi-variable logistic regression analysis revealed that blood loss during SIFE (OR = 1.001; 95% CI: 1.000-1.259; P = 0.012), postoperative lactate(OR = 1.212; 95% CI: 1.001-1.304; P = 0.015), grade V abdominal adhesions (OR = 2.518; 95% CI: 1.814-3.44; P = 0.024), and time for recovery of lactate <2 mmol/L (OR = 2.079; 95% CI: 1.599-3.616; P = 0.026) were associated with POI. Moreover, POI was also associated with prolonged postoperative stay in the hospital (HR = 3.291; 95% CI: 2.511-4.172; P = 0.014). Conclusion: Blood loss during operation, grade V abdominal adhesions, positive fluid balance within 48 h of operation, and time for recovery of lactate were the risk factors for POI after SIFE in patients with diffuse extensive abdominal adhesions.

Abstract
PURPOSE Postoperative ileus (POI) impairs patient recovery, prolonging hospital stay after major surgery in ovarian cancer (OvCa) patients. Thus, intraoperative bowel isolation is expected to reduce manipulation-related impairment. The aim of this study was to investigate the impact of intraoperative intestinal isolation bag on POI in OvCa patients submitted to primary surgery. METHODS A randomized trial including patients managed with or without isolation bag during OvCa primary surgery was conducted. Patients were selected by consecutive randomization. Primary endpoints were the time between surgery and resumption of bowel motility (as passage of first/continued flatus), assessing of postoperative nausea or vomiting and return to regular diet. Secondary endpoint was the impact of intestinal isolation bag on length of hospitalization in the two groups. RESULTS Ninety-two patients respecting inclusion criteria were eligible to be enrolled in the study (48 patients as Group 1 and 44 patients as Group 2). Thirty-eight (79.2%) patients, in which intraoperative isolation bag was used, experienced first/continued flatus within 3 days from surgery and they were susceptible to be discharged within 5 days, compared, respectively, to 34.3% of Group 2 (n = 15). Advantages were more evident in patients whose surgery took over 220 min (OR 0.02, CI 95% 0.001-0.57; p < 0.001) despite the type of surgical effort made. CONCLUSION Despite the small sample size, our study showed that the use of intestinal isolation bag can reduce incidence of POI and length of stay in OvCa patients submitted to primary cytoreductive surgery.

Abstract
PURPOSE Prolonged postoperative ileus (PPOI) is common after bowel resections, especially in Crohn's disease (CD). The pathophysiology of PPOI is not fully understood. PPOI could affect only the upper or lower gastrointestinal (GI) tract. The aim of this study was to assess risk factors for diverse types of PPOI, particularly to differentiate PPOI of upper and lower GI tract. METHODS A retrospective analysis of 163 patients with CD undergoing ileocecal resection from 2015 to 2020 in a single center was performed. PPOI of the upper GI tract was predefined as the presence of vomiting or use of nasogastric tube longer than the third postoperative day. Lower PPOI was predefined as the absence of defecation for more than three days. Independent risk factors were identified by multivariable logistic regression analysis. RESULTS Overall incidence of PPOI was 42.7%. PPOI of the upper GI tract was observed in 30.7% and lower PPOI in 20.9% of patients. Independent risk factors for upper PPOI included older age, surgery by a resident surgeon, hand-sewn anastomosis, prolonged opioid analgesia, and reoperation, while for lower PPOI included BMI ≤ 25 kg/m2, preoperative anemia, and absence of ileostomy. CONCLUSION This study identified different risk factors for upper and lower PPOI after ileocecal resection in patients with CD. A differentiated upper/lower type approach should be considered in future research and clinical practice. High-risk patients for each type of PPOI should be closely monitored, and modifiable risk factors, such as preoperative anemia and opioids, should be avoided if possible.

Postoperative Ileus and Postoperative Gastrointestinal Tract Dysfunction: Pathogenic Mechanisms and Novel Treatment Strategies Beyond Colorectal Enhanced Recovery After Surgery Protocols.

Abstract
Postoperative ileus (POI) and postoperative gastrointestinal tract dysfunction (POGD) are well-known complications affecting patients undergoing intestinal surgery. GI symptoms include nausea, vomiting, pain, abdominal distention, bloating, and constipation. These iatrogenic disorders are associated with extended hospitalizations, increased morbidity, and health care costs into the billions and current therapeutic strategies are limited. This is a narrative review focused on recent concepts in the pathogenesis of POI and POGD, pipeline drugs or approaches to treatment. Mechanisms, cellular targets and pathways implicated in the pathogenesis include gut surgical manipulation and surgical trauma, neuroinflammation, reactive enteric glia, macrophages, mast cells, monocytes, neutrophils and ICC's. The precise interactions between immune, inflammatory, neural and glial cells are not well understood. Reactive enteric glial cells are an emerging therapeutic target that is under intense investigation for enteric neuropathies, GI dysmotility and POI. Our review emphasizes current therapeutic strategies, starting with the implementation of colorectal enhanced recovery after surgery protocols to protect against POI and POGD. However, despite colorectal enhanced recovery after surgery, it remains a significant medical problem and burden on the healthcare system. Over 100 pipeline drugs or treatments are listed in Clin.Trials.gov. These include 5HT4R agonists (Prucalopride and TAK 954), vagus nerve stimulation of the ENS-macrophage nAChR cholinergic pathway, acupuncture, herbal medications, peripheral acting opioid antagonists (Alvimopen, Methlnaltexone, Naldemedine), anti-bloating/flatulence drugs (Simethiocone), a ghreline prokinetic agonist (Ulimovelin), drinking coffee, and nicotine chewing gum. A better understanding of the pathogenic mechanisms for short and long-term outcomes is necessary before we can develop better prophylactic and treatment strategies.

Thompson TB, Riviere BM, Knepley MG. An implicit discontinuous Galerkin method for modeling acute edema and resuscitation in the small intestine. MATHEMATICAL MEDICINE AND BIOLOGY-A JOURNAL OF THE IMA 2019; 36:513-548.

Abstract
Edema, also termed oedema, is a generalized medical condition associated with an abnormal aggregation of fluid in a tissue matrix. In the intestine, excessive edema can lead to serious health complications associated with reduced motility. A $7.5\%$ solution of hypertonic saline (HS) has been hypothesized as an effective means to reduce the effects of edema following surgery or injury. However, detailed clinical edema experiments can be difficult to implement, or costly, in practice. In this manuscript we introduce an implicit in time discontinuous Galerkin method with novel adaptations for modeling edema in the 3D layered physiology of the intestine. The model improves over early work via inclusion of the tissue intrinsic storage coefficient, and the effects of Starling overestimation for high venous pressures. Validation against a recent clinical experiment in HS resuscitation of acute edema is presented; the results support the clinical hypothesis that 7.5% HS solution may be effective in the resuscitation of acute edema formation. New results include an improved view into the effects of resuscitation on the hydrostatic pressure profile of edematous rats, effects on lumenal volume attenuation, relative fluid gain and an estimation of the impacts of both acute edema and resuscitation on intestinal motility.

Abstract
BACKGROUND Hypernatremia is a common problem affecting critically ill patients, whether due to underlying pathology or the subsequent result of hypertonic fluid resuscitation. Numerous studies have been published, suggesting that hypernatremia may adversely affect the vascular endothelial glycocalyx. Our study aimed to evaluate if high sodium concentration would impair the endothelial and glycocalyx barrier function and if stress conditions that simulate the shock microenvironment would exacerbate any observed adverse effects of hypernatremia. METHODS Human umbilical vein endothelial cells (HUVEC) were cultured in microfluidic channels subjected to flow conditions overnight to stimulate glycocalyx growth. Cells were then subjected to sodium (Na) concentrations of either 150 mEq/L or 160 mEq/L, with Hepes solution applied to media to maintain physiologic pH. Subsets of HUVEC were also exposed to hypoxia/reoxygenation and epinephrine (HR + Epi) to simulate shock insult, then followed by Na treatment. Perfusate was then collected 60 minutes and 120 minutes following treatments. Relevant biomarkers were then evaluated and HUVEC underwent fluorescent staining followed by microscopy. RESULTS Glycocalyx degradation as indexed by hyaluronic acid and syndecan-1 was elevated in all subgroups, particularly those subjected to HR + Epi with Na 160 mEq/L. Thickness of the glycocalyx as evaluated by fluorescent microscopy was reduced to half of baseline with Na 160 mEq/L and to one third of baseline with additional insult of HR + Epi. Endothelial activation/injury as indexed by soluble thrombomodulin was elevated in all subgroups. A profibrinolytic coagulopathy phenotype was demonstrated in all subgroups with increased tissue plasminogen activator levels and decreased plasminogen activator inhibitor-1 levels. CONCLUSION Our data suggest that hypernatremia results in degradation of the endothelial glycocalyx with further exacerbation by shock conditions. A clinical study using clinical measurements of the endothelial glycocalyx in critically ill or injured patients with acquired hypernatremia would be warranted.

Abstract
Traumatic injury resulting in hemorrhage is a prevalent cause of death worldwide. The current standard of care for trauma patients is to restore hemostasis by controlling bleeding and administering intravenous volume resuscitation. Adequate resuscitation to restore tissue blood flow and oxygenation is critical within the first hours following admission to assess severity and avoid complications. However, current clinical methods for guiding resuscitation are not sensitive or specific enough to adequately understand the patient condition. To better address the shortcomings of the current methods, an approach to monitor intestinal perfusion and oxygenation using a multiwavelength (470, 560, and 630 nm) optical sensor has been developed based on photoplethysmography and reflectance spectroscopy. Specifically, two sensors were developed using three wavelengths to measure relative changes in the small intestine. Using vessel occlusion, systemic changes in oxygenation input, and induction of hemorrhagic shock, the capabilities and sensitivity of the sensor were explored in vivo. Pulsatile and nonpulsatile components of the red, blue, and green wavelength signals were analyzed for all three protocols (occlusion, systemic oxygenation changes, and shock) and were shown to differentiate perfusion and oxygenation changes in the jejunum. The blue and green signals produced better correlation to perfusion changes during occlusion and shock, while the red and blue signals, using a new correlation algorithm, produced better data for assessing changes in oxygenation induced both systemically and locally during shock. The conventional modulation ratio method was found to be an ineffective measure of oxygenation in the intestine due to noise and an algorithm was developed based on the Pearson correlation coefficient. The method utilized the difference in phase between two different wavelength signals to assess oxygen content. A combination of measures from the three wavelengths provided verification of oxygenation and perfusion states, and showed promise for the development of a clinical monitor.

Abstract
Hemorrhage is the leading cause of preventable deaths in trauma patients. After presenting a brief history of hemorrhagic shock resuscitation, this article discusses damage control resuscitation and its adjuncts. Massively bleeding patients in hypovolemic shock should be treated with damage control resuscitation principles including limited crystalloid, whole blood or balance blood component transfusion to permissive hypotension, preventing hypothermia, and stopping bleeding as quickly as possible.

Abstract
BACKGROUND The aim of this study was to evaluate the related change in outcomes (mortality, complications) in patients undergoing trauma laparotomy (TL) with the implementation of damage control resuscitation (DCR). We hypothesized that the implementation of DCR in patients undergoing TL is associated with better outcomes. METHODS We analyzed 1,030 consecutive patients with TL. Patients were stratified into three phases: pre-DCR (2006-2007), transient (2008-2009), and post-DCR (2010-2013). Resuscitation fluids (crystalloids and blood products), injury severity score (ISS), vital signs, and laboratory (hemoglobin, international normalized ratio, lactate) parameters were recorded. Regression analysis was performed after adjusting for age, ISS, laboratory and vital parameters, comorbidities, and resuscitation fluids to identify independent predictors for outcomes in each phase. RESULTS Patient demographics and ISS remained the same throughout the three phases. There was a significant reduction in the volume of crystalloid (p = 0.001) and a concomitant increase in the blood product resuscitation (p = 0.04) in the post-DCR phase compared to the pre-DCR and transient DCR phases. Volume of crystalloid resuscitation was an independent predictor of mortality in the pre-DCR (OR [95% CI]: 1.071 [1.03-1.1], p = 0.01) and transient (OR [95% CI]: 1.05 [1.01-1.14], p = 0.01) phases; however, it was not associated with mortality in the post-DCR phase (OR [95% CI]:1.01 [0.96-1.09], p = 0.1). Coagulopathy (p = 0.01) and acidosis (p = 0.02) were independently associated with mortality in all three phases. CONCLUSION The implementation of DCR was associated with improved outcome in patients undergoing TL. There was a decrease in the use of damage control laparotomy, with a decrease in the use of crystalloid and an increase in the use of blood products. LEVEL OF EVIDENCE Prognostic study, level III.

Abstract
The resuscitation of traumatic hemorrhagic shock has undergone a paradigm shift in the last 20 years with the advent of damage control resuscitation (DCR). Major principles of DCR include minimization of crystalloid, permissive hypotension, transfusion of a balanced ratio of blood products, and goal-directed correction of coagulopathy. In particular, plasma has replaced crystalloid as the primary means for volume expansion for traumatic hemorrhagic shock. Predicting which patient will require DCR by prompt and accurate activation of a massive transfusion protocol, however, remains a challenge.

Abstract
The aim of this study was to explore the impact of 3% hypertonic saline (HS) intragastric administration for patients who underwent upper gastrointestinal surgery.During the postoperative period, 3% HS has been suggested as a means to improve the intestinal edema and reduce gastrointestinal complications.The medical records of 111 patients with HS intragastric administration following upper gastrointestinal surgery and 268 patients, served as control, were reviewed retrospectively. Propensity score matching was performed to adjust for selected baseline variables. Clinical outcomes, including early gastrointestinal function recovery, postoperative complications, and length of hospital stay, were compared according to the HS intragastric administration or not.HS intragastric administration was associated with prompt postoperative gastrointestinal function recovery, including first flatus (risk ratio [RR], 1.32; 95% confidence interval [CI], 0.89-1.65; P = 0.048) and feeding within 3 postoperative days (RR (95% CI), 0.57 (0.49-0.77); P = 0.036). Early ileus occurred in 25 of 108 patients with HS treatment versus 36 of 108 patients without HS treatment (RR (95% CI), 1.43 (0.63-2.15); P = 0.065). The patients with HS experienced a lower overall postoperative complication (odds ratio [OD] 0.57; 95% CI, 0.33-1.09; P = 0.063), including trend toward a decrease for infectious complications (15[13.9] vs 23[21.3]; P = 0.11; OD, 0.59; 95% CI, 0.29-1.22). There was a decreased incidence of anastomotic leakage (1[0.9] vs 7[6.5]; P = 0.033) and postoperative ileuas (5[4.6%] vs 11[10.2%]; P = 0.096) in the HS administration patients.Our study demonstrated beneficial postoperative clinical effects of HS intragastric administration in patients who had undergone upper gastrointestinal surgery, such as prompt postoperative gastrointestinal function recovery and reduced overall postoperative complications, which may be attributed to a reduced intestinal edema.

Abstract
Background Perioperative fluid restriction in a variety of operations has shown improvement of: complications, recovery of gastrointestinal function and length of stay (LOS). We investigated effects of crystalloid fluid restriction in pancreatic surgery. Our hypothesis: enhanced recovery of gastrointestinal function. Methods In this double-blinded randomized trial, patients scheduled to undergo pancreatoduodenectomy (PD) were randomized: standard (S:10ml/kg/hr) or restricted (R:5ml/kg/hr) fluid protocols. Primary endpoint: gastric emptying scintigraphically assessed on postoperative day 7. Results In 66 randomized patients, complications and 6-year survival were analyzed. 54 patients were analyzed in intention to treat: 24 S-group and 30 R-group. 32 patients actually underwent a PD and 16 patients had a palliative gastrojejunostomy bypass operation in the full protocol analysis. The median gastric emptying time (T½) was 104 minutes (S-group, 95% confidence interval: 74–369) versus 159 minutes (R-group, 95% confidence interval: 61–204) (P = 0.893, NS). Delayed gastric emptying occurred in 10 patients in the S-group and in 13 patients in the R-group (45% and 50%, P = 0.779, NS). The primary outcome parameter, gastric emptying time, did not show a statistically significant difference between groups. Conclusion A fluid regimen of 10ml/kg/hr or 5ml/kg/hr during pancreatic surgery did not lead to statistically significant differences in gastric emptying. A larger study would be needed to draw definite conclusions about fluid restriction in pancreatic surgery. Trial registration ISRCTN62621488

Abstract
Kidney injury commonly occurs after hemorrhagic shock. Previous studies have shown that post-hemorrhagic shock mesenteric lymph (PHSML) return negatively affects the kidneys and may induce injury. This study investigates the effect of PHSML drainage on the proteome in renal tissue. A controlled hemorrhagic shock model was established in the shock and shock+drainage groups. After 1 h of hypotension, fluid resuscitation was implemented within 30 min. Meanwhile, PHSML was drained in the shock+drainage group. After 3 h of resuscitation, renal tissue was extracted for proteome analysis using two-dimensional fluorescence difference gel electrophoresis. Differential proteins with intensities that either increased or decreased by 1.5-fold or greater were selected for trypsin digestion and analyzed by matrix-assisted laser desorption/ionization time-of-flight (TOF) mass spectrometry and tandem TOF/TOF mass spectrometry. Enzyme-linked immunosorbent assay was used to validate the identified partial proteins. Compared with the sham group, hnRNPC and Starp decreased in the shock group, whereas Hadha, Slc25a13, Atp5b, hnRNPC, Starp, Rps3, and actin were downregulated in the shock+drainage group. Meanwhile, Atp5b and actin decreased in the shock+drainage group relative to the shock group. The identified proteins can be classified into different categories, such as cell proliferation (hnRNPC, Strap, and Rps3), energy metabolism (Hadha, Atp5b, and Slc25a13), cell motility, and cytoskeleton (actin). Moreover, enzyme-linked immunosorbent assay measurement validated the changed levels of Atp5b and Actg2. Our findings provide a starting point for investigating the functions of differentially expressed proteins in acute kidney injury induced by hemorrhagic shock. These findings hold great potential for the development of therapeutic interventions.

The aims of this narrative review were to provide an update of classification systems, preventive techniques, pathophysiological mechanisms, and treatment options for established POI. METHODS The Web of Science, MEDLINE, PubMed and Google Scholar databases were searched using the key phrases 'ileus', 'postoperative ileus' and 'definition', for relevant studies published in English from January 1997 to August 2014. RESULTS POI is still a problematic and frequent complication of surgery. Fluid overload, exogenous opioids, neurohormonal dysfunction, and gastrointestinal stretch and inflammation are key mechanisms in the pathophysiology of POI. Evidence is supportive of thoracic epidural analgesia, avoidance of salt and water overload, alvimopan and gum chewing as measures for the prevention of POI, and should be incorporated into perioperative care protocols. Minimal access surgery and avoidance of nasogastric tubes may also help. Novel strategies are emerging, but further studies are required for the treatment of prolonged POI, where evidence is still lacking. CONCLUSIONS Although POI is often inevitable, methods to reduce its duration and facilitate recovery of postoperative gastrointestinal function are evolving rapidly. Utilisation of standardised diagnostic classification systems will help improve applicability of future studies.

Lobo DN, Awad S. Should chloride-rich crystalloids remain the mainstay of fluid resuscitation to prevent 'pre-renal' acute kidney injury?: con. Kidney Int 2014; 86:1096-105. [PMID: 24717302 PMCID: PMC4255073 DOI: 10.1038/ki.2014.105] [Citation(s) in RCA: 94] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2013] [Revised: 01/14/2014] [Accepted: 01/24/2014] [Indexed: 02/07/2023]
Abstract
The high chloride content of 0.9% saline leads to adverse pathophysiological effects in both animals and healthy human volunteers, changes not seen after balanced crystalloids. Small randomized trials confirm that the hyperchloremic acidosis induced by saline also occurs in patients, but no clinical outcome benefit was demonstrable when compared with balanced crystalloids, perhaps due to a type II error. A strong signal is emerging from recent large propensity-matched and cohort studies for the adverse effects that 0.9% saline has on the clinical outcome in surgical and critically ill patients when compared with balanced crystalloids. Major complications are the increased incidence of acute kidney injury and the need for renal replacement therapy, and that pathological hyperchloremia may increase postoperative mortality. However, there are no large-scale randomized trials comparing 0.9% saline with balanced crystalloids. Some balanced crystalloids are hypo-osmolar and may not be suitable for neurosurgical patients because of their propensity to cause brain edema. Saline may be the solution of choice used for the resuscitation of patients with alkalosis and hypochloremia. Nevertheless, there is evidence to suggest that balanced crystalloids cause less detriment to renal function than 0.9% saline, with perhaps better clinical outcome. Hence, we argue that chloride-rich crystalloids such as 0.9% saline should be replaced with balanced crystalloids as the mainstay of fluid resuscitation to prevent ‘pre-renal' acute kidney injury.

Abstract
PURPOSE OF REVIEW Enteral nutrition has emerged as one of the most effective treatments in the early management of patients with acute pancreatitis. The original rationale for nutrition in acute pancreatitis, dating back to the mid-20th century, was to provide full nutritional requirements but avoid stimulating exocrine pancreatic secretion. The purpose of this article is to review the recent clinical studies of enteral nutrition in acute pancreatitis to revise the rationale and develop a contemporary conceptual framework for nutritional management of this disease. RECENT FINDINGS Several recent randomized controlled trials dispel the outdated concept of 'pancreatic rest', which equates with gut neglect, and offer 'gut rousing' as a preferred concept. The new concept postulates that gastrointestinal (dys)function has a discernible impact on the outcomes of patients with acute pancreatitis. Further, timely administration of appropriate intraluminal modalities prevents or mitigates the gastrointestinal dysfunction. SUMMARY Nutritional management in acute pancreatitis should aim primarily at maintaining the gastrointestinal function. Providing full nutritional requirements and avoiding pancreatic exocrine stimulation should be considered as secondary aims.

Effect of Hypotensive Resuscitation with a Novel Combination of Fluids in a Rabbit Model of Uncontrolled Hemorrhagic Shock. PLoS One 2013; 8:e66916. [PMID: 23805284 PMCID: PMC3689663 DOI: 10.1371/journal.pone.0066916] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2013] [Accepted: 05/10/2013] [Indexed: 01/12/2023] Open
Abstract
Objective The aim of this study was to compare the effects of hypotensive and normotensive resuscitation with a novel combination of fluids via lactate Ringer’s solution (LRS), 6% hydroxyethyl starch 130/0.4 solution (HES), and 7.5% hypertonic saline solution (HSS) at early stage of uncontrolled hemorrhagic shock (UHS) before hemostasis. Methods New Zealand white rabbits (n = 32) underwent UHS by transecting the splenic parenchyma, followed by blood withdrawal via the femoral artery to target mean arterial pressure (MAP) of 40–45 mmHg. Animals were distributed randomly into 4 groups (n = 8): in group Sham, sham operation was performed; in group HS, UHS was untreated; in group HS-HR, UHS was treated by hypotensive resuscitation with HSS and LRS+HES (ratio of 2∶1) to MAP of 50–55 mmHg; in group HS-NR, UHS was treated by normotensive resuscitation with HSS and LRS+HES (ratio of 2∶1) to MAP of 75–80 mmHg. Outcomes of hemodynamics, inflammatory and oxidative response, and other metabolic variables were measured and the histopathological studies of heart, lung and kidney were performed at the end of resusucitation. Results Hypotensive resuscitation with the novel combination of fluids for UHS rabbits decreased blood loss, maintained better stabilization of hemodynamics, and resulted in relatively higher hematocrit and platelet count, superior outcomes of blood gas, and lower plasma lactate concentration. Besides, hypotensive resuscitation attenuated the inflammatory and oxidative response significantly in UHS rabbits. Conclusion Hypotensive resuscitation with the novel combination of fluids via HSS and LRS+HES (ratio of 2∶1) has an effective treatment at early stage of UHS before hemostasis.

Abstract
BACKGROUND Management of the open abdomen is an increasingly common part of surgical practice. The purpose of this review is to examine the scientific background for the use of temporary abdominal closure (TAC) in the open abdomen as a way to modulate the local and systemic inflammatory response, with an emphasis on decompression after abdominal compartment syndrome (ACS). METHODS A review of the relevant English language literature was conducted. Priority was placed on articles published within the last 5 years. RESULTS/CONCLUSION Recent data from our group and others have begun to lay the foundation for the concept of TAC as a method to modulate the local and/or systemic inflammatory response in patients with an open abdomen resulting from ACS.

Damage control resuscitation is associated with a reduction in resuscitation volumes and improvement in survival in 390 damage control laparotomy patients. Ann Surg 2011; 254:598-605.

Abstract
OBJECTIVE To determine whether implementation of damage control resuscitation (DCR) in patients undergoing damage control laparotomy (DCL) translates into improved survival. BACKGROUND DCR aims at preventing coagulopathy through permissive hypotension, limiting crystalloids and delivering higher ratios of plasma and platelets. Previous work has focused only on the impact of delivering higher ratios (1:1:1). METHODS A retrospective cohort study was performed on all DCL patients admitted between January 2004 and August 2010. Patients were divided into pre-DCR implementation and DCR groups and were excluded if they died before completion of the initial laparotomy. The lethal triad was defined as immediate postoperative temperature less than 95°F, international normalized ratio more than 1.5, or a pH less than 7.30. RESULTS A total of 390 patients underwent DCL. Of these, 282 were pre-DCR and 108 were DCR. Groups were similar in demographics, injury severity, admission vitals, and laboratory values. DCR patients received less crystalloids (median: 14 L vs 5 L), red blood cells (13 U vs 7 U), plasma (11 U vs 8 U), and platelets (6 U vs 0 U) in 24 hours, all P < 0.05. DCR patients had less evidence of the lethal triad upon intensive care unit arrival (80% vs 46%, P < 0.001). 24-hour and 30-day survival was higher with DCR (88% vs 97%, P = 0.006 and 76% vs 86%, P = 0.03). Multivariate analysis controlling for age, injury severity, and emergency department variables, demonstrated DCR was associated with a significant increase in 30-day survival (OR: 2.5, 95% CI: 1.10-5.58, P = 0.028). CONCLUSION In patients undergoing DCL, implementation of DCR reduces crystalloid and blood product administration. More importantly, DCR is associated with an improvement in 30-day survival.

Abstract
REASONS FOR PERFORMING STUDY Colic is a common reason for elimination from equine endurance competitions and has recently been identified as the leading cause of mortality in this group of horses. Hydration and electrolyte derangements are often severe, but are probably related to endurance exercise and not necessarily the episode of colic. Better understanding of the causes of colic and the expected outcome is needed to guide treatment decisions in endurance horses. OBJECTIVES To describe the history, case details, clinical examination, laboratory, treatment and outcomes for horses presenting to equine referral centres for treatment of colic associated with endurance competition and to identify variables associated with prolonged hospitalisation. METHODS Thirty-six horses from 2 equine referral centres were included in the analysis. In addition to descriptive statistics, Cox proportional hazards models were used to evaluate factors associated with length of hospitalisation. RESULTS A diagnosis of open or ileus was made in the majority of horses (56%). Salmonellosis and enteritis (Salmonella negative) were also recognised (16%). Exploratory abdominal surgery was performed in 5 of the horses. Only one of 36 horses did not survive to discharge. Previous eliminations from competition (negative association) and total i.v. fluids within the first 24 h (positive association) of admission were both associated with length of hospitalisation. CONCLUSIONS Endurance horses with colic typically respond to medical treatment but in some cases hospitalisation may be prolonged. The role of Salmonella infections in endurance horses with colic requires further research. POTENTIAL RELEVANCE Despite potentially severe clinical and laboratory derangements, equine practitioners should make owners aware that the prognosis for competing endurance horses with colic is good when treated appropriately.

Abstract
PURPOSE OF REVIEW To highlight recent developments relating perioperative fluid therapy to gastrointestinal function by reviewing clinically pertinent English language articles mainly from January 2010 to March 2011. RECENT FINDINGS The control of fluid and electrolyte balance involves multiple processes in which the gastrointestinal tract plays an integral role. Diseases affecting the gastrointestinal tract commonly cause fluid and electrolyte disturbance. Similarly, intravenous fluid therapy in the perioperative period can affect gastrointestinal function and have a bearing on postoperative outcome. Striking a balance, in terms of both fluid composition and volume, is likely to reduce the morbidity associated with interstitial edema, a frequently observed occurrence with contemporary perioperative fluid regimens. This balance may be best achieved using individualized and goal-directed approaches to fluid therapy, in order to provide fluid when it is needed and in the correct quantities. SUMMARY In planning strategies of fluid therapy, the possibility of adverse effects on the gastrointestinal tract should be considered, as this is likely to have an impact on fluid and electrolyte balance and postoperative outcome.
