AbstractIntroductionQTc prolongation has been reported in adults following cardiopulmonary bypass; however, this phenomenon has not been studied in children with congenital cardiac disease. This study's aim was to formally assess QTc in children undergoing cardiac surgery.MethodsPre-operative and post-operative electrocardiograms during hospital stays were prospectively analysed on 107 consecutive patients under 18 years of age undergoing cardiac surgery. QTc was measured manually in leads II, V4, and V5. Measurements of 440 and 480 milliseconds were used to categorise patients. Peri-procedural data included bypass and cross-clamp time, medications, and electrolyte measurements. Outcome data included arrhythmias, length of mechanical ventilation, and hospital stay. Patients with post-operative new bundle branch block or ventricularly paced rhythm were excluded.ResultsIn all, 59 children were included, out of which 26 had new QTc over 440 milliseconds and 6 of 59 had new QTc over 480 milliseconds post-operatively. The mean increase in post-operative QTc was 25 milliseconds, p=0.0001. QTc over 480 was associated with longer cross-clamp time, p=0.003. Other risk factors were not associated with post-operative QTc prolongation. This phenomenon was transient with normalisation occurring in 67% of patients over 60 hours on average. One patient with post-operative QTc over 440 milliseconds developed ventricular tachycardia. There was no correlation between prolonged QTc and duration of mechanical ventilation, or hospital stay.ConclusionA significant number of children undergoing cardiac surgery showed transient QTc prolongation. The precise aetiology of QT prolongation was not discerned, though new QTc over 480 milliseconds was associated with longer cross-clamp time. In this cohort, transient QTc prolongation was not associated with adverse sequela.

Objectives: This study aims to analyze the nosocomial infection factors in post–cardiac surgery extracorporeal membrane oxygenation (ECMO) supportive treatment (pCS-ECMO). Methods: The clinical data of the pCS-ECMO patients who obtained nosocomial infections (NI) were collected and analyzed retrospectively. Among the 74 pCS-ECMO patients, 30 occurred with NI, accounting for 40.5%; a total of 38 pathogens were isolated, including 22 strains of Gram-negative bacteria (57.9%), 15 strains of Gram-positive bacteria (39.5%), and 1 fungus (2.6%). Results: Multidrug-resistant strains were highly concentrated, among which Acinetobacter baumannii and various coagulase-negative staphylococci were the main types; NI was related to mechanical ventilation time, intensive care unit (ICU) residence, ECMO duration, and total hospital stay, and the differences were statistically significant (P < .05). The binary logistic regression analysis indicated that ECMO duration was a potential independent risk factor (OR = 0.992, P = .045, 95.0% CI = 0.984-1.000). Conclusions: There existed significant correlations between the secondary infections of pCS-ECMO and mechanical ventilation time, ICU residence, ECMO duration, and total hospital stay; therefore, hospitals should prepare appropriate preventive measures to reduce the incidence of ECMO secondary infections.

Abstract Objectives This study was aimed to assess the benefits of early tracheostomy (ET) compared with late tracheostomy (LT) on postoperative outcomes in pediatric cardiac surgical patients. Design Present one is a prospective, observational study. Setting The study was conducted at a cardiac surgical intensive care unit (ICU) of a tertiary care hospital. Participants All pediatric patients below 10 years of age, who underwent tracheostomy after cardiac surgery from January2019 to december2019, were subdivided into two groups according to the timing of tracheostomy: “early” if done before 7 days or “late” if done after 7 days postcardiac surgery. Interventions ET versus LT was measured in the study. Results Out of all 1,084 pediatric patients who underwent cardiac surgery over the study period, 41 (3.7%) received tracheostomy. Sixteen (39%) patients underwent ET and 25 (61%) underwent LT. ET had advantages by having reduced risk associations with the following variables: preoperative hospital stay (p = 0.0016), sepsis (p = 0.03), high risk surgery (p = 0.04), postoperative sepsis (p = 0.001), C-reactive protein (p = 0.04), ventilator-associated pneumonia (VAP; p = 0.006), antibiotic escalation (p = 0.006), and antifungal therapy (p = 0.01) requirement. Furthermore, ET was associated with lesser duration of mechanical ventilation (p = 0.0027), length of ICU stay (LOICUS; p = 0.01), length of hospital stay (LOHS; p = 0.001), lesser days of feed interruption (p = 0.0017), and tracheostomy tube change (p = 0.02). ET group of children, who had higher total ventilation-free days (p = 0.02), were decannulated earlier (p = 0.03) and discharged earlier (p = 0.0089). Conclusion ET had significant benefits in reduction of postoperative morbidities with overall shorter mechanical ventilation, LOICUS, and LOHS, better nutrition supplementation, lesser infection, etc. These benefits may promote faster patient convalescence and rehabilitation with reduced hospital costs.

Abstract Background Neutrophil–lymphocyte ratio (NLR) is a valuable indicator for evaluating inflammation and adverse outcomes after cardiac surgery. The objective of this study was to evaluate the association of perioperative NLR with clinical outcomes in infants undergoing congenital heart surgery with cardiopulmonary bypass. Methods We performed a retrospective review of 424 consecutive infants (≤ 1 year) undergoing cardiac surgery between January 2019 and September 2019. Neonates (≤ 28 days) and patients with incomplete NLR data were excluded. The study endpoint was a composite of poor outcomes after surgery. We assess the correlation between perioperative NLR and clinical outcomes. A receiver operating characteristic curve and multivariable logistic regression were applied to identify the prognosis performance of postoperative NLR for poor outcomes. Results A total of 68 (16%) infants experienced at least one of the poor outcomes. Postoperative NLR on the third day after the surgery showed the best prognostic significance (AUC = 0.763, 95%CI 0.700–0.826) among perioperative period, with a cut-off value of 2.05. Postoperative NLR was also strongly correlated with mechanical ventilation time, length of ICU and hospital stay (p < 0.001). Multivariable logistic regression revealed that elevated postoperative NLR (OR 3.722, 95%CI 1.895–7.309, p < 0.001) was an independent risk factor for poor outcomes in infants after cardiac surgery. Conclusions Postoperative NLR was correlated with increased mechanical ventilation time, length of ICU and hospital stay. Elevated postoperative NLR was an independent predictor for poor outcomes after cardiac surgery in infants.

The Impact

Background. Hyperoxia has long been perceived as a desirable or at least an inevitable part of cardiopulmonary bypass. Recent evidence suggest that it might have multiple detrimental effects on patient homeostasis. The aim of the study was to identify the determinants of supra-physiological values of partial oxygen pressure during on-pump cardiac surgery and to assess the impact of hyperoxia on clinical outcomes. Materials and methods. Retrospective data analysis of the institutional research database was performed to evaluate the effects of hyperoxia in patients undergoing elective cardiac surgery with cardiopulmonary bypass, 246 patients were included in the final analysis. Patients were divided in three groups: mild hyperoxia (MHO, PaO2 100–199 mmHg), moderate hyperoxia (MdHO, PaO2 200–299 mmHg), and severe hyperoxia (SHO, PaO2 >300 mmHg). Postoperative complications and outcomes were defined according to standardised criteria of the Society of Thoracic Surgeons. Results. The extent of hyperoxia was more immense in patients with a lower body mass index (p = 0.001) and of female sex (p = 0.005). A significant link between severe hyperoxia and a higher incidence of infectious complications (p – 0.044), an increased length of hospital stay (p – 0.044) and extended duration of mechanical ventilation (p < 0.001) was confirmed. Conclusions. Severe hyperoxia is associated with an increased incidence of postoperative infectious complications, prolonged mechanical ventilation, and increased hospital stay.

The Mean

Our objective was to identify factors associated with the duration of mechanical ventilation (MV) postoperative to cardiac surgery and assess the association between duration of endotracheal intubation, length of stay in the Intensive Care Unit (ICU) and hospital. Longitudinal, retrospective study of medical records of 116 adults undergoing cardiac surgery from March 2012 to May 2013. The mean age was 57±14 years, predominantly male and coronary artery bypass grafting surgery (52.6%). The MV time was 15.25(7.66 to 23.68) hours. Associated with longer MV was the age (r=0.5,p<0.001), comorbidities (r=0.344,p<0.001), cardiopulmonary bypass time (r=0.244,p=0.008), duration of continuous sedation (r=0.607,p<0.001), sedative doses (r=0.4, p<0.001), time of vasoconstrictors and vasodilators (r=0.711, p< 0.001, r=0.368, p<0.001), drainage of the 1st time (r=0.201, p<0.031), presence of drains (r=0.445, p<0.001), postoperative complications (r=0.524, p< 0.001) and hospital stay. Our data confirms that both preoperative, transoperative and postoperative variables prolong the VM and therefore the hospital stay.

Unplanned readmission to the intensive care unit (ICU) is associated with poor prognosis, longer hospital stay, increased costs, and higher mortality rate. In this retrospective study, involving 1368 patients, the risk factors for and outcomes of ICU readmission after cardiac surgery were analyzed. The readmission rate was 5.9%, and the most common reason for readmission was cardiac issues. Preoperative risk factors were comorbid conditions, mechanical ventilation, and admission route. Perioperative risk factors were nonelective surgery, duration of cardiopulmonary bypass, and longer operation time. Postoperative risk factors were prolonged mechanical ventilation time, new-onset arrhythmia, unplanned reoperation, massive blood transfusion, prolonged inotropic infusions, and complications. Other factors were high blood glucose level, hemoglobin level, and score on the Acute Physiology and Chronic Health Evaluation II. In-hospital stay was longer and late mortality was higher in the readmitted group. These data could help clinical practitioners create improved ICU discharge protocols or treatment algorithms to reduce length of stay or to reduce readmissions.

Objective To assess risk factors of acute kidney injury in congenital cardiac disease following cardiac surgery with cardiopulmonary bypass in children. Methods A 50% postoperative creatinine increase was regarded as the criterion of acute kidney injury. 124 children aged 3 years or little undergoing cardiac surgery were divided into three groups: (1) negative AKI (-); (2) AKI (+) with an increase in postoperative creatinine from 150% to 200%; and (3) AKI (++) with an increase in postoperative creatinine by more than 200%. Demographics, and preoperative, intraoperative, and postoperative variables were evaluated for associations with AKI using univariate and multiple logistic regression analysis. Results Several variables, including mortality, preoperative albumin and creatinine levels, cardiopulmonary bypass duration, and postoperative creatinine levels, were significant differences among the three groups (P < 0.05). Multiple regression analysis demonstrated that three risk factors, age (OR, 0.962; 95% CI, 0.925 to 1.000; P = 0.046), intraoperative red blood cell transfusion (OR, 1.003; 95% CI, 1.001 to 1.005; P = 0.030), and cardiopulmonary bypass duration (OR, 1.024; 95% CI, 1.016 to 1.032; P = 0.000) were independently associated with AKI after cardiac surgery. Conclusions This study showed that younger age, incremental intraoperative red blood cell transfusion, and prolonged cardiopulmonary bypass duration were independently associated with acute kidney injury after cardiac surgery. The type of congenital cardiac disease should be included in the analysis of acute kidney injury.
