Fluid management and goal-directed therapy as an adjunct to Enhanced Recovery After Surgery (ERAS)
(Canadian Journal of Anesthesia, 2016-01-01) Miller, Timothy Ellis; Roche, Anthony Michael; Mythen, Michael Gerard
Optimal perioperative fluid management is an important component of Enhanced Recovery After Surgery (ERAS) pathways. Fluid management within ERAS should be viewed as a continuum through the preoperative, intraoperative, and postoperative phases. Each phase is important for improving patient outcomes, and suboptimal care in one phase can undermine best practice within the rest of the ERAS pathway. The goal of preoperative fluid management is for the patient to arrive in the operating room in a hydrated and euvolemic state. To achieve this, prolonged fasting is not recommended, and routine mechanical bowel preparation should be avoided. Patients should be encouraged to ingest a clear carbohydrate drink two to three hours before surgery. The goals of intraoperative fluid management are to maintain central euvolemia and to avoid excess salt and water. To achieve this, patients undergoing surgery within an enhanced recovery protocol should have an individualized fluid management plan. As part of this plan, excess crystalloid should be avoided in all patients. For low-risk patients undergoing low-risk surgery, a “zero-balance” approach might be sufficient. In addition, for most patients undergoing major surgery, individualized goal-directed fluid therapy (GDFT) is recommended. Ultimately, however, the additional benefit of GDFT should be determined based on surgical and patient risk factors. Postoperatively, once fluid intake is established, intravenous fluid administration can be discontinued and restarted only if clinically indicated. In the absence of other concerns, detrimental postoperative fluid overload is not justified and “permissive oliguria” could be tolerated.

Frailty in the End-Stage Lung Disease or Heart Failure Patient: Implications for the Perioperative Transplant Clinician.
(Journal of cardiothoracic and vascular anesthesia, 2019-05) Bottiger, Brandi A; Nicoara, Alina; Snyder, Laurie D; Wischmeyer, Paul E; Schroder, Jacob N; Patel, Chetan B; Daneshmand, Mani A; Sladen, Robert N; Ghadimi, Kamrouz
The syndrome of frailty for patients undergoing heart or lung transplantation has been a recent focus for perioperative clinicians because of its association with postoperative complications and poor outcomes. Patients with end-stage cardiac or pulmonary failure may be under consideration for heart or lung transplantation along with bridging therapies such as ventricular assist device implantation or venovenous extracorporeal membrane oxygenation, respectively. Early identification of frail patients in an attempt to modify the risk of postoperative morbidity and mortality has become an important area of study over the last decade. Many quantification tools and risk prediction models for frailty have been developed but have not been evaluated extensively or standardized in the cardiothoracic transplant candidate population. Heightened awareness of frailty, coupled with a better understanding of distinct cellular mechanisms and biomarkers apart from end-stage organ disease, may play an important role in potentially reversing frailty related to organ failure. Furthermore, the clinical management of these critically ill patients may be enhanced by waitlist and postoperative physical rehabilitation and nutritional optimization.

Goal-directed or goal-misdirected - how should we interpret the literature?
(Crit Care, 2010) Roche, Anthony M; Miller, Timothy E
Goal-directed therapy (GDT) can be a vague term, meaning different things to different people and, depending on the clinical environment, sometimes even different things to the same person. It can refer to perioperative fluid management, clinicians driving oxygen delivery to supramaximal values, early treatment of sepsis in the emergency department, and even to restriction of perioperative crystalloids with the goal of maintaining preadmission body weight. Understandably, strong opinions about GDT vary; some clinicians consider it essential for perioperative care, others completely ineffective in critically ill patients. This commentary aims to further position the excellent review by Lees and colleagues in the context of the critical care and perioperative setting.

Improving Outcomes in Colorectal Surgery by Sequential Implementation of Multiple Standardized Care Programs.
(J Am Coll Surg, 2015-08) Keenan, Jeffrey E; Speicher, Paul J; Nussbaum, Daniel P; Adam, Mohamed Abdelgadir; Miller, Timothy E; Mantyh, Christopher R; Thacker, Julie KM
BACKGROUND: The purpose of this study was to examine the impact of the sequential implementation of the enhanced recovery program (ERP) and surgical site infection bundle (SSIB) on short-term outcomes in colorectal surgery (CRS) to determine if the presence of multiple standardized care programs provides additive benefit. STUDY DESIGN: Institutional ACS-NSQIP data were used to identify patients who underwent elective CRS from September 2006 to March 2013. The cohort was stratified into 3 groups relative to implementation of the ERP (February 1, 2010) and SSIB (July 1, 2011). Unadjusted characteristics and 30-day outcomes were assessed, and inverse proportional weighting was then used to determine the adjusted effect of these programs. RESULTS: There were 787 patients included: 337, 165, and 285 in the pre-ERP/SSIB, post-ERP/pre-SSIB, and post-ERP/SSIB periods, respectively. After inverse probability weighting (IPW) adjustment, groups were balanced with respect to patient and procedural characteristics considered. Compared with the pre-ERP/SSIB group, the post-ERP/pre-SSIB group had significantly reduced length of hospitalization (8.3 vs 6.6 days, p = 0.01) but did not differ with respect to postoperative wound complications and sepsis. Subsequent introduction of the SSIB then resulted in a significant decrease in superficial SSI (16.1% vs 6.3%, p < 0.01) and postoperative sepsis (11.2% vs 1.8%, p < 0.01). Finally, inflation-adjusted mean hospital cost for a CRS admission fell from $31,926 in 2008 to $22,044 in 2013 (p < 0.01). CONCLUSIONS: Sequential implementation of the ERP and SSIB provided incremental improvements in CRS outcomes while controlling hospital costs, supporting their combined use as an effective strategy toward improving the quality of patient care.

Jehovah's Witnesses and cardiac surgery: a single institution's experience.
(Transfusion, 2014-10) McCartney, Sharon; Guinn, Nicole; Roberson, Russell; Broomer, Bob; White, William; Hill, Steven
BACKGROUND: Based on biblical doctrines, patients of the Jehovah's Witness faith refuse allogeneic blood transfusion. Cardiac surgery carries a high risk of blood transfusion, but has been performed in Jehovah's Witnesses for many years. The literature contains information on the outcomes of this cohort, but does not detail the perioperative care of these patients. This article describes a single institution's experience in perioperative care of Jehovah's Witnesses undergoing cardiac surgery. STUDY DESIGN AND METHODS: A chart review of adult Jehovah's Witness patients undergoing cardiac surgery at Duke University between January 2005 and June 2012 was completed. Institutional protocols regarding preoperative erythropoietin (EPO) therapy and intraoperative isovolemic hemodilution are detailed. Patient demographics and use of various blood conservation techniques are described. Hemoglobin (Hb) at various points throughout the perioperative management, hospital length of stay, and mortality are reviewed as indicators of outcome. RESULTS: Forty-five Jehovah's Witness patients underwent cardiac surgery at Duke University Medical Center. Preoperative EPO increased the mean Hb by 1.2 g/dL before surgery. Intraoperative normovolemic hemodilution was used in 37 patients with intraoperative mean nadir Hb of 10.3 g/dL. Antifibrinolytics and desmopressin were commonly used as coagulation adjuncts. Mean cardiopulmonary bypass time was 137 minutes, with mean nadir temperature of 30.5°C. The mean length of hospital stay was 6.2 days, with mean intensive care unit stay of 1.7 days. This cohort had zero 90-day mortality in the perioperative period. CONCLUSIONS: This case series demonstrates that bloodless cardiac surgery can be performed in select patients refusing allogeneic blood transfusion.

Monitoring needs and goal-directed fluid therapy within an enhanced recovery program.
(Anesthesiol Clin, 2015-03) Minto, Gary; Scott, Michael J; Miller, Timothy E
Patients having major abdominal surgery need perioperative fluid supplementation; however, enhanced recovery principles mitigate against many of the factors that traditionally led to relative hypovolemia in the perioperative period. An estimate of fluid requirements for abdominal surgery can be made but individualization of fluid prescription requires consideration of clinical signs and hemodynamic variables. The literature supports goal-directed fluid therapy. Application of this evidence to justify stroke volume optimization in the setting of major surgery within an enhanced recovery program is controversial. This article places the evidence in context, reviews controversies, and suggests implications for current practice and future research.

Pathophysiology of major surgery and the role of enhanced recovery pathways and the anesthesiologist to improve outcomes.
(Anesthesiol Clin, 2015-03) Scott, Michael J; Miller, Timothy E
Enhanced recovery pathways have been increasingly adopted into surgical specialties with the aim of reducing the stress response and improving the metabolic response to surgical insult. Enhanced recovery pathways encompass a large range of perioperative elements that together aim to restore a patient's gut function, mobility, function and well-being to preoperative levels as soon as feasible after major surgery. There is increasing evidence that rapid recovery and return to normal function reduces complications. This may not just have a benefit by reducing morbidity and mortality but also have an effect on long-term survival. There also may be additional benefits for patients with cancer.

Perioperative fluid and hemodynamic management within an enhanced recovery pathway.
(Journal of surgical oncology, 2017-10) Manning, Michael W; Dunkman, William Jonathan; Miller, Timothy E
Goal-directed fluid therapy (GDFT) seeks to improve outcomes through individualized optimization of oxygen delivery using IV fluid and vasoactive infusions. Trials of GDFT show clinical benefits over traditional liberal fluid administration, but fail to demonstrate benefits when compared to a restrictive strategy within an optimized enhanced recovery protocol. The ideal monitors, hemodynamic goals, and fluid administration strategy are not well established but may be less important than rational application of thoughtful fluid management strategies.

Perioperative management of the bleeding patient.
(British journal of anaesthesia, 2016-12) Ghadimi, K; Levy, JH; Welsby, IJ
Perioperative bleeding remains a major complication during and after surgery, resulting in increased morbidity and mortality. The principal causes of non-vascular sources of haemostatic perioperative bleeding are a preexisting undetected bleeding disorder, the nature of the operation itself, or acquired coagulation abnormalities secondary to haemorrhage, haemodilution, or haemostatic factor consumption. In the bleeding patient, standard therapeutic approaches include allogeneic blood product administration, concomitant pharmacologic agents, and increasing application of purified and recombinant haemostatic factors. Multiple haemostatic changes occur perioperatively after trauma and complex surgical procedures including cardiac surgery and liver transplantation. Novel strategies for both prophylaxis and therapy of perioperative bleeding include tranexamic acid, desmopressin, fibrinogen and prothrombin complex concentrates. Point-of-care patient testing using thromboelastography, rotational thromboelastometry, and platelet function assays has allowed for more detailed assessment of specific targeted therapy for haemostasis. Strategic multimodal management is needed to improve management, reduce allogeneic blood product administration, and minimize associated risks related to transfusion.

Pharmacologic management of perioperative pulmonary hypertension.
(J Cardiovasc Pharmacol, 2014-04) Cheng, Julie W; Tonelli, Adriano R; Pettersson, Gosta; Krasuski, Richard A
Perioperative pulmonary hypertension can originate from an established disease or acutely develop within the surgical setting. Patients with increased pulmonary vascular resistance are consequently at greater risk for complications. Despite the various specific therapies available, the ideal therapeutic approach in this patient population is not currently clear. This article describes the basic principles of perioperative pulmonary hypertension and reviews the different classes of agents used to promote pulmonary vasodilation in the surgical setting.

Prothrombin Complex Concentrates for Bleeding in the Perioperative Setting.
(Anesth Analg, 2016-05) Ghadimi, Kamrouz; Levy, Jerrold H; Welsby, Ian J
Prothrombin complex concentrates (PCCs) contain vitamin K-dependent clotting factors (II, VII, IX, and X) and are marketed as 3 or 4 factor-PCC formulations depending on the concentrations of factor VII. PCCs rapidly restore deficient coagulation factor concentrations to achieve hemostasis, but like with all procoagulants, the effect is balanced against thromboembolic risk. The latter is dependent on both the dose of PCCs and the individual patient prothrombotic predisposition. PCCs are approved by the US Food and Drug Administration for the reversal of vitamin K antagonists in the setting of coagulopathy or bleeding and, therefore, can be administered when urgent surgery is required in patients taking warfarin. However, there is growing experience with the off-label use of PCCs to treat patients with surgical coagulopathic bleeding. Despite their increasing use, there are limited prospective data related to the safety, efficacy, and dosing of PCCs for this indication. PCC administration in the perioperative setting may be tailored to the individual patient based on the laboratory and clinical variables, including point-of-care coagulation testing, to balance hemostatic benefits while minimizing the prothrombotic risk. Importantly, in patients with perioperative bleeding, other considerations should include treating additional sources of coagulopathy such as hypofibrinogenemia, thrombocytopenia, and platelet disorders or surgical sources of bleeding. Thromboembolic risk from excessive PCC dosing may be present well into the postoperative period after hemostasis is achieved owing to the relatively long half-life of prothrombin (factor II, 60-72 hours). The integration of PCCs into comprehensive perioperative coagulation treatment algorithms for refractory bleeding is increasingly reported, but further studies are needed to better evaluate the safe and effective administration of these factor concentrates.

Reduced length of hospital stay in colorectal surgery after implementation of an enhanced recovery protocol.
(Anesth Analg, 2014-05) Miller, TE; Thacker, JK; White, WD; Mantyh, C; Migaly, J; Jin, J; Roche, AM; Eisenstein, EL; Edwards, R; Anstrom, KJ; Moon, RE; Gan, TJ
BACKGROUND: Enhanced recovery after surgery (ERAS) is a multimodal approach to perioperative care that combines a range of interventions to enable early mobilization and feeding after surgery. We investigated the feasibility, clinical effectiveness, and cost savings of an ERAS program at a major U. S. teaching hospital. METHODS: Data were collected from consecutive patients undergoing open or laparoscopic colorectal surgery during 2 time periods, before and after implementation of an ERAS protocol. Data collected included patient demographics, operative, and perioperative surgical and anesthesia data, need for analgesics, complications, inpatient medical costs, and 30-day readmission rates. RESULTS: There were 99 patients in the traditional care group, and 142 in the ERAS group. The median length of stay (LOS) was 5 days in the ERAS group compared with 7 days in the traditional group (P < 0.001). The reduction in LOS was significant for both open procedures (median 6 vs 7 days, P = 0.01), and laparoscopic procedures (4 vs 6 days, P < 0.0001). ERAS patients had fewer urinary tract infections (13% vs 24%, P = 0.03). Readmission rates were lower in ERAS patients (9.8% vs 20.2%, P = 0.02). DISCUSSION: Implementation of an enhanced recovery protocol for colorectal surgery at a tertiary medical center was associated with a significantly reduced LOS and incidence of urinary tract infection. This is consistent with that of other studies in the literature and suggests that enhanced recovery programs could be implemented successfully and should be considered in U.S. hospitals.

State-of-the-art fluid management in the operating room.
(Best Practice and Research: Clinical Anaesthesiology, 2014-09) Miller, Timothy E; Raghunathan, Karthik; Gan, Tong J
The underlying principles guiding fluid management in any setting are very simple: maintain central euvolemia, and avoid salt and water excess. However, these principles are frequently easier to state than to achieve. Evidence from recent literature suggests that avoidance of fluid excess is important, with excessive crystalloid use leading to perioperative weight gain and an increase in complications. A zero-balance approach aimed at avoiding fluid excess is recommended for all patients. For major surgery, there is a sizeable body of evidence that an individualized goal-directed fluid therapy (GDFT) improves outcomes. However, within an Enhanced Recovery program only a few studies have been published, yet so far GDFT has not achieved the same benefit. Balanced crystalloids are recommended for most patients. The use of colloids remains controversial; however, current evidence suggests they can be beneficial in intraoperative patients with objective evidence of hypovolemia.

Systematic Review and Guidelines for Perioperative Management of Pediatric Patients Undergoing Major Plastic Surgery Procedures, with a Focus on Free Tissue Transfer.
(Plastic and reconstructive surgery, 2022-08) Mountziaris, Paschalia M; Rudolph, Christina M; Fournier, Craig T; Haykal, Siba; Ricci, Joseph A; Rezak, Kristen M; Patel, Ashit
Background
Microsurgical free tissue transfer has been successfully implemented for various reconstructive applications in children. The goal of this study was to identify the best available evidence on perioperative management of pediatric patients undergoing free tissue transfer and to use it to develop evidence-based care guidelines.
Methods
A systematic review was conducted in the PubMed, Embase, Scopus, and Cochrane Library databases. Because a preliminary search of the pediatric microsurgical literature yielded scant data with a low level of evidence, pediatric anesthesia guidelines for healthy children undergoing major operations were also included. Exclusion criteria included vague descriptions of perioperative care, case reports, and studies of syndromic or chronically ill children.
Results
Two hundred four articles were identified, and 53 met inclusion criteria. Management approaches specific to the pediatric population were used to formulate recommendations. High-quality data were found for anesthesia, analgesia, fluid administration/blood transfusion, and anticoagulation (Level I Evidence). Lower quality evidence was identified for patient temperature (Level III Evidence) and vasodilator use (Level IV Evidence). Key recommendations include administering sevoflurane for general anesthesia, implementing a multimodal analgesia strategy, limiting preoperative fasting, restricting blood transfusions until hemoglobin level is less than 7 g/dl unless the patient is symptomatic, and reserving chemical venous thromboembolism prophylaxis for high-risk patients.
Conclusions
Pediatric-specific guidelines are important, as they acknowledge physiologic differences in children, which may be overlooked when extrapolating from adult studies. These evidence-based recommendations are a key first step toward standardization of perioperative care of pediatric patients undergoing plastic surgical procedures, including free tissue transfer, to improve outcomes and minimize complications.
