Evaluation of Postoperative Delirium in Cardiac Surgery Patients With the SDACS Screening Tool: A Multicenter-Multiphase Study

April 6, 2025 No Comments

This study developed and validated the SDACS screening tool to predict postoperative delirium in cardiac surgery patients. Conducted across three academic hospitals with 920 participants, it identified four key predictors: chronic opioid use, hearing impairment, benzodiazepine history, and poor postoperative sleep. The tool demonstrated strong predictive power (AUC = 0.897), offering clinicians a practical instrument to guide early interventions.

Machine Learning for In-hospital Mortality Prediction in Critically Ill Patients With Acute Heart Failure: A Retrospective Analysis Based on the MIMIC-IV Database

April 3, 2025 No Comments

This study developed machine learning (ML) models to predict in-hospital mortality among ICU patients with acute heart failure (AHF) using data from the MIMIC-IV database. Among five tested algorithms, XGBoost showed the highest predictive accuracy (AUC: 0.82) and outperformed traditional clinical scoring systems. The model incorporated 18 clinical variables from the first 24 hours of ICU admission to aid early intervention strategies.

A Review of Recent Advances in Anesthetic Drugs for Patients Undergoing Cardiac Surgery

March 8, 2025 No Comments

This review explores recent advancements in anesthetic drugs for cardiac surgery. With no standard protocol for anesthesia in these procedures, the article examines commonly used agents such as opioids (fentanyl, sufentanil, remifentanil), volatile anesthetics, and novel drugs like dexmedetomidine and remimazolam. The study highlights opioid-free anesthesia approaches, innovative drug delivery systems, and enhanced recovery techniques to improve patient outcomes and reduce complications.

The Incidence, Risk Factors, and Hospital Mortality of Prolonged Mechanical Ventilation Among Cardiac Surgery Patients: A Systematic Review and Meta-Analysis

December 20, 2024 No Comments

This systematic review analyzes prolonged mechanical ventilation (PMV) post-cardiac surgery, finding an incidence rate of 20%. PMV, defined as ventilation lasting ≥24 hours, is linked to in-hospital mortality (odds ratio: 14.13). Key risk factors include advanced age, female sex, ejection fraction <50%, and body mass index >28 kg/m². PMV also correlates with conditions like chronic renal failure and prolonged cardiopulmonary bypass time. These insights highlight the need for targeted prevention and management strategies.

Anesthesia for Minimally Invasive Cardiac Surgery: The Bonn Heart Center Protocol

July 17, 2024 No Comments

This article outlines the anesthetic management protocol for minimally invasive cardiac surgery (MICS) at the Bonn Heart Center. It covers preoperative assessment, tailored anesthesia induction, and intraoperative techniques designed to maintain hemodynamic stability and ensure optimal ventilation. Advanced monitoring methods, including transesophageal echocardiography (TEE), processed EEG, and near-infrared spectroscopy (NIRS), are utilized to optimize patient safety. The article emphasizes the importance of peripheral cannulation techniques for cardiopulmonary bypass (CPB) and discusses the necessity of a multidisciplinary approach to perioperative care to enhance recovery and patient outcomes.
