This prospective interventional study aimed at evaluating the efficacy of intraoperative TTE to alter patient management in high-risk and extensively monitored surgical patients susceptible to hemodynamic instability. The study included 52 hemodynamically unstable high-risk abdominal, vascular, or thoracic surgery patients. Patients were anesthetized, and focused TTE was performed when intraoperative hemodynamic instability occurred (hypotension or low cardiac output for a period of ≥3 minutes). Cardiac output monitoring system using pulse contour analysis was established before induction of anesthesia. The definitive therapy leading to an alteration of management was guided by the results of the focused TTE. Differences between intended and actual therapies and changes in management were documented as the primary end points. The analysis of TTE quality and description of pathophysiologic cardiovascular findings were the secondary end points. Sample size estimation and statistical analyses were performed with the statistical software R (www.r-project.org). Changes of management were noted in 33 patients (66%; 95% confidence interval, 52.11%–77.61%) and 38 hemodynamic situations (46.34%; 95% confidence interval, 35.95%–57.06%) of the 50 hemodynamically unstable patients examined by additional focused TTE. Transthoracic echocardiography identified pathologic findings in 47 patients: hypovolemia (66%), left ventricular dysfunction (8%), right ventricular overload (22%), and right-sided heart failure (4%). Lack of randomization and the absence of a control group were the major limitations of this study.","PeriodicalId":22104,"journal":{"name":"Survey of Anesthesiology","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84837991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a need for well-designed large prospective studies to assess ED risk factors and eliminate confounders as well as a need for standardized screening, evaluation tools, and data sharing in order to easily compare outcomes for researchers of pediatric ED (characterized by crying, sobbing, thrashing about, and disorientation following anesthesia). Emergence delirium should therefore be considered a “vital sign” to be consistently documented in the pediatric postanesthesia recovery period. The Paediatric Anaesthesia Emergence Delirium (PAED) scale, which assigns scores based on exhibited behavior, is used to identify ED currently. Because of problems in assessing normal behavior in children (especially those with special needs) in a stressful clinical environment, a better protocol is needed. A baseline preoperative and postoperative PAEDwould be useful to provide a comparative reference point in the recovery room and reduce the risk of falsepositive results. Routine monitoring and preoperative and postoperative PAED scores treated as vital signs in the pediatric units will yield better ED assessments and care. The best approach to reducing ED should be preventing its occurrence rather than treating the symptoms and pain with α2-adrenergic agonists. Standardized and routine monitoring of ED will ensure better understanding of the risk factors and prevention of this phenomenon leading to better delivery of care to children and faster recovery in the postoperative setting.","PeriodicalId":22104,"journal":{"name":"Survey of Anesthesiology","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91507490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the authors provide a meta-analysis of the data extracted from the systematic review to calculate the precision of these noninvasive CO monitoring devices when used perioperatively by following pooled estimates. The authors gathered data from the systematic review in order to calculate the following 4 variables: (1) the pooled estimate of the mean difference between the tested method of bolus TD and the noninvasive reference method (bias), (2) the pooled estimate of the standard deviation (precision) of the bias, (3) the pooled estimate of the 95% confidence intervals of the bias, and (4) the pooled estimate of the percentage of error (PE). An acceptable agreement between the tested and the reference method was defined as a pooled estimate (PE) of 30% or greater. Despite it being crucial in critical care management, CO, the basis of measuring oxygen delivery to end organs, has been demonstrably undermonitored in clinical settings. New noninvasive techniques and older methods abound for monitoring CO including pulse wave transit time (PWTT), noninvasive pulse contour analysis (niPCA), partial CO2 rebreathing (CO2r), and thoracic electrical bioimpedance (TEB), yet the “go-to” in the clinical setting is the traditional invasive technique of bolus TD. Mean CO was 4.78 L/min in both methods. The overall random-effects pooled bias was −0.13 L/min (−2.38 to 2.12 L/min) and PE 47% with high interstudy sensitivity heterogeneity (I = 83%, P < 0.001). Despite the many advances in medical technology since the early 2000s, both TEB and CO2r have not shown significantly increased agreement when compared with bolus TD (PE for TEB was 37% in 1999, 43% in 2010, and 42% in 2016 in this metaanalysis; CO2r PE was similar to 2010: 44.5% against 40% in this meta-analysis). Recent techniques, such as PWTTand the niPCA, have a PE of 62% for PWTT and 45% for niPCA.
