Assessment of microcirculatory alteration by a vascular occlusion test using near-infrared spectroscopy in pediatric cardiac surgery: effect of cardiopulmonary bypass.

Objectives: Cardiopulmonary bypass cause microcirculatory alterations. Near infrared spectroscopic measurement of tissue oxygen saturation and vascular occlusion test are novel technologies for assessing the microcirculatory function of peripheral tissue specifically in patients undergoing cardiac surgery with cardiopulmonary bypass.Our study aimed to evaluate dynamic microcirculatory function using the vascular occlusion testing during cardiac surgery in pediatric patients.

Infection profile of patients with extracorporeal membrane oxygenation in paediatric cardiac surgery ICU.

Aim: We investigated the risk of increased nosocomial infections and the associated pathogens in patients who underwent paediatric cardiovascular surgery and were put on extracorporeal membrane oxygenation support. We studied the duration of extracorporeal membrane oxygenation use and other variables that may be associated with increased nosocomial infection risk.

Methods: Patients who were treated with an extracorporeal membrane oxygenation in paediatric cardiovascular surgery ICU between 2010 and 2020 were included in this retrospective study.

A 5-year analysis of Candida bloodstream infections in the paediatric cardiovascular surgery ICU of a tertiary care centre.

Background: Candida infections have become one of the most common causes of morbidity and mortality in paediatric ICUs, especially following complex surgeries, all over the world. Therefore, we conducted a 5-year analysis of Candida bloodstream infections in our tertiary paediatric cardiovascular surgery ICU.

Methods: One thousand nine hundred and thirty four children, 0-16-year-old, who underwent paediatric cardiovascular surgery between January 2016-June 2021 were enrolled in this retrospective study.

Acute Changes in Myocardial Expression of Heat Shock Proteins and Apoptotic Response Following Blood, delNido, or Custodiol Cardioplegia in Infants Undergoing Open-Heart Surgery.

Stress caused by cardioplegic ischemic arrest was shown to alter the expression levels of heat shock proteins (Hsp), but little is known about their effects, particularly on pediatric hearts. This study aimed to investigate whether myocardial cellular stress and apoptotic response changes due to different cardioplegia (CP) solutions during cardiopulmonary bypass (CPB) in infants and to determine their influence on surgical/clinical outcomes. Therefore, twenty-seven infants for surgical closure of ventricular septal defect were randomly assigned to a CP solution: normothermic blood (BCP), delNido (dNCP), and Custodiol (CCP).

Neurological complications after pediatric cardiac surgery.

Background: The number of pediatric patients who survive open-heart surgery has increased in recent years and the complications seen in this patient group continue to decrease with each technological advance, including new surgical and neuroprotective techniques and the improvement in surgeons' experience with this patient population. However, neurological complications, which are the most feared and difficult to manage, require long-term follow-up, and increase hospital costs remain a leading cause of mortality and morbidity in this cohort.

Results: We evaluated the neurological physical examination, cranial computed tomography (CT), and magnetic resonance (MRI) records of 162 pediatric patients with neurological symptoms lasting more than 24 h after undergoing heart surgery in our clinic between June 2012 and May 2020.
