Background and aims: Children with congenital heart disease (CHD) are at risk of deterioration in the face of common childhood illnesses, and their resuscitation and acute management is often best achieved with the guidance of CHD experts. Access to such expertise may be limited outside specialty heart centers and the fragility of these patients is cause for discomfort among many emergency medicine physicians. An understanding of the differences in macrocognition of these clinicians could shed light on some of the causes of discomfort and facilitate the development of a sociotechnological solution to this problem. Methods: Cardiac intensivists (CHD experts) and pediatric emergency medicine physicians (non-CHD experts) in a major academic cardiac center were interviewed using the critical decision method. Interview transcripts were coded deductively based on Klein’s macrocognitive framework and inductively to allow for new or modified characterization of dimensions. Results: While both CHD-experts and non-CHD experts relied on the macrocognitive functions of sensemaking, naturalistic decision making and detecting problems, the specific data and mental models used to understand the patients and course of therapy differed between CHD-experts and non-CHD experts. Conclusion: Characterization of differences between the macrocognitive processes of CHD experts and non-CHD experts can inform development of sociotechnological solutions to augment decision making pertaining to the acute management of pediatric CHD patients.

AbstractWorldwide figures suggest that two percent of appropriate referrals for neonatal extracorporeal membrane oxygenation turn out to have previously covert congenital heart disease. This is despite the fact that expert cardiological evaluation is routine prior to cannulation. The experience in the United Kingdom includes such a case which is reported here. The implications for the role of pediatric cardiologists in such a service are considered.

Background: Hypocapnia is suggested in decreasing pulmonary vascular resistance in cyanotic congenital heart disease patients undergoing definitive repair. But its effects on cerebral and renal circulation are unclear. Hence the effect of changes in arterial blood carbon dioxide tensions (PaCo2 ) on cerebral (ScO2 %) and renal (SsO2 %) oxygenation indices using Near Infrared spectroscopy (NIRS) is examined. Methods: We did a prospective observational study in sixty-eight children who underwent elective cardiac surgery for various cyanotic congenital heart diseases. PaCo2 , ScO2 % and SsO2 % were obtained before induction of anesthesia, after anesthesia induction at normocapnic or mild hypercapnic ventilation (EtCo2 =40 mmHg) and again at hypocapnic ventilation (EtCo2 =30 mmHg). Regression analysis was done between PaCo2 and NIRS-C/ScO2 % and PaCo2 and NIRS-R/SsO2 % at both EtCo2 40 and 30 mmHg. Repeated measure analysis performed to evaluate the significance of change in NIRS-C and NIRS-R from pre-anesthesia induction to when EtCo2 was 40 and then 30 mmHg post anesthesia induction. Results: With decrease in EtCo2 , PaCo2 (p=0.0001), NIRS-C (p=0.0001) and NIRS-R (p=0.0001) decreased significantly. At EtCo2 of 40 and 30 mmHg, PaCo2 had significant positive correlation with NIRS-C (R2 =0.77, p=0.0001 and R2 =0.92, p=0.0001 respectively) and had insignificant correlation with NIRS-R (R2 =0.03, p=0.12 and R2 =0.008, p=0.46 respectively). Significant changes in NIRS-C {p=0.0001} and NIRS-R {p=0.0001} occurred from pre-induction to when EtCo2 was 40 and then to 30 mmHg. Conclusion: A decrease in NIRS-C and NIRS-R is probably from decreased cerebral and splanchnic blood flow during hypocapnic ventilation, leading to demand supply mismatch. Hypocapnic ventilation in cyanotic children has potential to cause cerebral hypoxia.
