Cardiac anesthesia risk score

BACKGROUND: Patients with previous coronary artery bypass grafting often require invasive coronary angiography (ICA). However, for these patients, the procedure is technically more challenging and has a higher risk of complications. Observational studies suggest that computed tomography cardiac angiography (CTCA) may facilitate ICA in this group, but this has not been tested in a randomized controlled trial. METHODS: This study was a single-center, open-label randomized controlled trial assessing the benefit of adjunctive CTCA in patients with previous coronary artery bypass grafting referred for ICA...

BACKGROUND: Intraoperative hypotension is a risk factor for perioperative adverse outcomes and highly prevalent in older patients. Frailty has been associated with hemodynamic instability but its impact on postinduction hypotension is unclear. Therefore, we assessed the association between frailty and postinduction hypotension in older patients. METHODS: We retrospectively evaluated electronic medical records of patients aged ≥ 65 years who were assessed for preoperative frailty and underwent noncardiac surgery under general anesthesia...

OBJECTIVES: The primary purpose of this study was to identify factors associated with the development of arterial line-related limb ischemia in patients on extracorporeal membrane oxygenation (ECMO). The authors also sought to characterize and report the outcomes of patients who developed arterial line-related limb ischemia. DESIGN: Retrospective cohort study. SETTING: A single academic tertiary referral ECMO center. PARTICIPANTS: Consecutive patients who were treated with ECMO over 6 years...

BACKGROUND: Phosphodiesterase inhibitors are known to relieve symptoms in the setting of heart failure, although their effects in restrictive ventricular physiology have been poorly characterized. We explored the association between the use of milrinone and volume administration during the first 72 hours following surgical repair of tetralogy of Fallot (TOF). METHODS: We reviewed all cases of primary surgical repair of TOF with pulmonary stenosis or atresia at Boston Children's Hospital between 2011 and 2020...

BACKGROUND: Classic neuraxial techniques, such as thoracic epidural anesthesia, or alternative approaches like the paravertebral block, are not indicated in cardiac surgery due to increased bleeding risk. To provide satisfactory analgesia without the need for excessive opioid use, novel ultrasound techniques gained popularity and are of growing interest. The pectoralis nerve block II (PECS II) has been shown to provide good postoperative analgesia in modified radical mastectomy and might also be suitable for minimally invasive cardiac surgery...

BACKGROUND: Outcomes of individuals with adult congenital heart disease (ACHD) who are socioeconomically disadvantaged and cared for in a cardio-obstetric programs are lacking. OBJECTIVES: To describe clinical characteristics, maternal pregnancy outcomes and contraceptive uptake of individuals with ACHD in an urban cardio-obstetric program. STUDY DESIGN: Retrospective data were collected for individuals with ACHD seen in the Maternal Fetal Medicine-Cardiology Joint Program at Montefiore Health System between 2015-2021 and compared by modified World Health Organization (mWHO) class I,II vs...

Neurological pupil index (NPi) calculated by automated pupillometry predicts clinical outcomes in critically ill patients. However, there are few data on intraoperative NPi and postoperative outcome after cardiac surgery. We evaluated the relationships between intraoperative NPi and clinical outcomes, such as delirium, in cardiac surgery patients. NPi was measured at baseline, after anesthesia induction, at 30 min intervals after initiation of cardiopulmonary bypass or anastomosis of coronary artery bypass graft, and at skin closure...

BACKGROUND: Cognitive decline following surgery is a common concern among elderly individuals. Leukocyte telomere length (LTL) can be assessed as a biological clock connected to an individual lifespan. However, the mechanisms causing this inference are still not fully understood. As a result of this, LTL has the potential to be useful as an aging-related biomarker for assessing delayed neurocognitive recovery (dNCR) and related diseases. METHODS: For this study, 196 individuals over 60 who were scheduled due to major non-cardiac surgical operations attended neuropsychological testing before surgery, followed by additional testing one week later...

OBJECTIVE: New-onset atrial fibrillation (NOAF), an important postoperative complication, has pertinent inflammatory links. Motivated by the encouraging literature on the prognostic role of hypoalbuminemia, leukocytic indices [LIs: neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR)], systemic inflammation response index (SIRI=NLR×monocyte) and platelet-leukocytic indices [PLIs: platelet-to-lymphocyte ratio (PLR)], systemic immune inflammation index (SII=NLR×platelet), aggregate index of systemic inflammation (AISI=NLR×platelet×monocyte), we sought to investigate the NOAF-predictive value of preoperative albumin-adjusted indices (aa-LIs and aa-PLIs) in an off-pump coronary artery bypass grafting (OPCABG) setting...

OBJECTIVE: Severe postoperative pain has been shown to affect many patients following minimally invasive cardiac surgeries (MICS). Multimodal pain management with regional anesthesia, particularly by delivery of local anesthetics using a paravertebral catheter (PVC), has been shown to reduce pain in operations involving thoracotomy incisions. However, few studies have reported high-quality safety and efficacy outcomes of PVCs following MICS. METHODS: Patients who underwent MICS at Vancouver General Hospital between 2016 and 2019 ( N = 123) were reviewed for perioperative opioid-narcotic use...

Right ventricular (RV) dysfunction is common after left ventricular assist device (LVAD) implantation leading to clinical right heart failure (RHF) associated with worsened survival and quality of life. It is likely that intraoperative events such as anesthesia induction play a role in the development or unmasking of RV dysfunction in addition to known effects from hemodynamic changes that occur after LVAD implantation. The EACH-LVAD Study is a prospective, single-center, single-arm, observational cohort study of adult patients with advanced heart failure undergoing durable LVAD implantation with standard anesthesia induction...

BACKGROUND: The prognostic nutritional index (PNI) is a nutritional indicator and predictor of various diseases. However it is unclear whether PNI can be a predictor of perioperative ischemic stroke. This study aims to evaluate the association of the preoperative PNI and ischemic stroke in patients undergoing non-cardiac surgery. METHODS: The retrospective cohort study included patients who underwent noncardiac surgery between January 2008 and August 2019. The patients were divided into PNI ≥ 38...

BACKGROUND: Pre-procedural fasting to reduce aspiration risk is usual care prior to surgery requiring anesthesia. Prolonged fasting, however, can result in dehydration and may adversely affect patient experience and outcomes. Previous studies suggest that providing a supplemental beverage to patients undergoing cardiac and a variety of other surgical procedures improves patients' subjective assessment of thirst and hunger and potentially decreases the need for inotrope and vasopressor therapy...

OBJECTIVES: Clarify the prognostic value of the Johns Hopkins Hospital Nutrition Support (JHHNS) score on clinical outcomes in older patients undergoing cardiovascular surgery with cardiopulmonary bypass (CPB). DESIGN: A retrospective observational study. SETTING: A teaching and university hospital and tertiary referral center. PARTICIPANTS: The authors analyzed 328 older patients aged ≥65 who underwent cardiovascular surgery with CPB in 2020...

BACKGROUND: Preoperative cardiovascular risk assessment is one of the main principles before noncardiac surgeries. Cardiac stress imaging, such as myocardial perfusion scan (MPS), is a proposed cardiovascular risk evaluation method according to the latest guidelines. Yet, its efficacy, along with the cost-effectiveness of the method, has been questioned in previous studies. Our study aims to evaluate the utility of N-terminal pro-b-type natriuretic peptide (NT-proBNP) level measurement in predicting postoperative cardiovascular complications in candidates who have undergone an MPS before surgery and compare the results...

BACKGROUND: The perioperative risk factors that cause severe morbidity and prolongation of postoperative hospital stay after cardiac surgery should be determined. Various scores have been used to predict morbidity and mortality. Preoperative blood counts are considered potential biomarkers of inflammation and oxidative stress. Inflammatory and immune imbalances may have a significant impact on postoperative adverse events. The present study aimed to investigate the association and potential predictive properties of red cell distribution width/lymphocyte ratio (RLR) for major adverse events in adult patients who underwent coronary surgery with cardiopulmonary bypass...

OBJECTIVES: The aim of this analysis was to compare the effect of extubating in the operating room (OR) versus and the intensive care unit (ICU) among patients undergoing coronary artery bypass grafting (CABG). DESIGN: A retrospective cohort analysis. SETTING: Ten cardiac referral hospitals in Latin America; participants of the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II). PARTICIPANTS: The database included a total of 4,015 patients who underwent primary and isolated CABG surgery and were ≥18 years old, of whom 205 patients were extubated in the OR...

OBJECTIVES: The authors aimed to develop a simple prediction score to help identify patients at high risk of low-cardiac-output syndrome after adult cardiac surgery. DESIGN: A single-center, retrospective, observational study. SETTING: At a tertiary hospital. PARTICIPANTS: Adult patients who underwent on-pump cardiac surgery between April 2016 and March 2021. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Among the 2,806 patients retained for final analyses, 355 (12...

OBJECTIVE: To identify risk factors and develop a pretest scoring system to differentiate patients with heparin-induced thrombocytopenia (HIT) in the mechanical circulatory support (MCS) population. The authors present a modified "4TMCS " scoring system, which considers the "type of mechanical circulatory support" that may help identify patients at risk for developing postoperative HIT. DESIGN: A retrospective cohort study. Patients who underwent cardiac surgery were categorized into 3 groups: (1) normal platelet count, (2) thrombocytopenia with a negative HIT test, and (3) thrombocytopenia with a positive HIT test...

BACKGROUND: One of the worst types of severe chest injuries seen by clinicians is flail chest. This study aims to measure the overall mortality rate among flail chest patients and then to correlate mortality with several demographic, pathologic, and management factors. METHODOLOGY: A retrospective observational study tracked a total of 376 flail chest patients admitted to the emergency intensive care unit (EICU) and surgical intensive care unit (SICU) at Zagazig University over 120 months...
