Intraoperative renal and cerebral tissue oxygen saturation measurements to predict postoperative acute kidney injury in pediatric cardiac surgery: a prospective observational study.

Purpose: Pediatric patients undergoing cardiac surgery are at risk of developing postoperative acute kidney injury (AKI). We hypothesized that a reduction in intraoperative renal (SrO) or cerebral (ScO) tissue oxygen saturation is associated with postoperative AKI.

Methods: We conducted a prospective observational study including fifty pediatric patients with non-cyanotic heart disease undergoing elective surgical repair with cardiopulmonary bypass.

Aortic Transvalvular Gradient Mis-Quantification.

Mitral regurgitation (MR) can occasionally mimic aortic stenosis (AS) on echocardiographic Doppler imaging, leading to diagnostic challenges. We present the case of a 55-year-old man undergoing minimally invasive mitral valve surgery for severe MR caused by posterior mitral valve leaflet prolapse. Preoperative transthoracic echocardiography revealed severe MR with no significant aortic valve abnormalities.

Prognostic Value of Perioperative Near-Infrared Spectroscopy Monitoring for Postoperative Acute Kidney Injury in Pediatric Cardiac Surgery: A Systematic Review.

IntroductionPostoperative acute kidney injury (AKI) is a common postoperative complication in cardiac surgery, with varying reported incidences and prognostic factors. Renal hypoperfusion is believed to be a key factor contributing to postoperative AKI. Near-infrared spectroscopy (NIRS) monitoring, which assesses regional tissue saturation (RSO), has been suggested as a tool to predict postoperative AKI.

Impact of Persistent Pulmonary Hypertension of the Newborn in Neonates with Dextro-transposition of the Great Arteries.

Objectives: This study aimed to assess the impact of persistent pulmonary hypertension of the newborn (PPHN) on perioperative morbidity and mortality in patients with dextro-transposition of the great arteries. Secondarily, we evaluated the association between postoperative outcomes and intraoperative variables including the duration of cardiopulmonary bypass, cerebral oxygen desaturation, and hypotension.

Design: Retrospective observational study.

Cerebral oxygenation during pediatric congenital cardiac surgery and its association with outcome: a retrospective observational study.

Purpose: Non-invasive cerebral oxygen saturation (ScO) monitoring is an established tool in the intraoperative phase of pediatric congenital cardiac surgery (CCS). This study investigated the association between ScO and postoperative outcome by investigating both baseline ScO values and intraoperative desaturations from baseline.

Methods: All CCS procedures performed in the period 2010-2017 in our institution in which ScO was monitored were included in this historical cohort study.

Onset of brain injury in infants with prenatally diagnosed congenital heart disease.

Background: The exact onset of brain injury in infants with congenital heart disease (CHD) is unknown. Our aim was, therefore, to assess the association between prenatal Doppler flow patterns, postnatal cerebral oxygenation and short-term neurological outcome.

Methods: Prenatally, we measured pulsatility indices of the middle cerebral (MCA-PI) and umbilical artery (UA-PI) and calculated cerebroplacental ratio (CPR).

Using extra systoles and the micro-fluid challenge to predict fluid responsiveness during cardiac surgery.

Fluid responsiveness prediction is difficult during cardiac surgery. The micro-fluid challenge (micro-FC; rapid central infusion of 50 ml) and the extrasystolic method utilising post-extrasystolic preload increases may predict fluid responsiveness. Two study windows during coronary artery bypass graft surgery were defined, 1: After anaesthesia induction until surgical incision, 2: Left internal mammarian artery surgical preparation period.
