Background In pediatric cardiac surgery, perioperative management has evolved from slow weaning of mechanical ventilation in the intensive care unit to “ultra‐fast‐track” anesthesia with early extubation (EE) in theater to promote a faster recovery. The strategy of EE has not been assessed in adults with congenital heart disease, a growing population of patients who often require surgery. Methods And Results Data were collected retrospectively on all patients >16 years of age who underwent adult congenital heart surgery in our tertiary center between December 2012 and January 2020. Coarsened exact matching was performed for relevant baseline variables. Overall, 711 procedures were performed: 133 (18.7%) patients underwent EE and 578 (81.3%) patients received conventional extubation. After matching, patients who received EE required less inotropic or vasopressor support in the early postoperative period (median Vasoactive‐inotropic score 0.5 [0.0–2.0] versus 2.0 [0.0–3.5]; P <0.0001) and had a lower total net fluid balance than patients after conventional extubation (1168±723 versus 847±733 mL; P =0.0002). The overall reintubation rate was low at 0.3%. EE was associated with a significantly shorter postoperative length of stay in higher dependency care units before a “step‐down” to ward‐based care (48 [45–50] versus 50 [47–69] hours; P =0.004). Lower combined intensive care unit and high dependency unit costs were incurred by patients who received EE compared with patients who received conventional extubation (£3949 [3430–4222] versus £4166 [3893–5603]; P <0.0001). Conclusions In adult patients undergoing surgery for congenital heart disease, EE is associated with a reduced need for postoperative hemodynamic support, a shorter intensive care unit stay, and lower health‐care‐related costs.
Introduction Adult patients with congenital heart disease (ACHD) are a heterogeneous population and a variety of procedures are performed in ACHD centers, which differ significantly from those performed in the general adult population. Therefore, ACHD patients have not been included in the development of risk stratification models, such as the EuroSCORE. We assessed the utility of the components of the EuroSCORE in predicting in-hospital mortality around surgery in a large cohort of ACHD patients and tested a modified risk score for the ACHD population. Methods Data were collected retrospectively on all consecutive patients >16 years who underwent congenital heart disease surgery in a large tertiary center in 2015–18. Preoperative characteristics and perioperative outcomes were collected from clinical records and databases. Wilcoxon rank sum test, Fisher's test and Logistic regression analysis were used to identify predictors of in-hospital death. Variables significant on univariate linear regression were used to create a risk score for each patient, either attributing 1 point for each risk factor (unweighted model), or weighing this by its log(Odds ratio) in the logistic regression model (weighted score). Receive operator characteristic (ROC) analysis with calculation of the areas under the curve (AUC) was used to assess the performance of each scoring system in predicting in-hospital mortality. Results A total of 476 operations occurred in 459 patients who underwent cardiac surgery during the study period. Age at surgery was 35.9±14.7 years, 258 (56.2%) were male, 231 (51.3%) patients had a previous sternotomy. There were 19 (4.1%) in-hospital deaths. Certain components of EuroSCORE were very rarely observed in our ACHD patients and were not included in the analysis. Of components of the EuroSCORE, female sex (OR 3.79, 95% CI: 1.42–11.89, p=0.01), functional NYHA class>2 (OR 7.65, 95% CI: 2.35–29.26, p=0.001), left ventricle dysfunction (OR 3.14, 95% CI: 1.22–8.01, p=0.02), previous surgery (OR 5.33, 95% CI: 1.41–34.68, p=0.03), emergency or urgent surgery (OR 7.96, 95% CI: 3.1–21.99, p<0.0001), renal dysfunction (MDRD GFR<60 OR 6.56, 95% CI: 1.73–20.52, p=0.002), endocarditis (OR 7.71, 95% CI: 1.6–28.85, p=0.004), and a critical preoperative state (OR 28.65, 95% CI: 5.11–147.93, p<0.0001) were predictive of an adverse perioperative outcome. Moreover, the number of previous sternotomies was predictive of mortality (OR 2.45, 95% CI: 1.58–3.85, p<0.0001). Both the unweighted (AUC 0.78, 95% CI: 70.6–85.3), but especially the weighted risk score (AUC 0.82, 95% CI: 74.8–89) had an optimal discriminative power (Figure). Conclusions While several components of the EuroSCORE are relevant to ACHD patients, an ACHD-specific scoring system for predicting perioperative mortality is needed. In this analysis, we propose a simplified risk score for ACHD patients undergoing surgery, which performs well in this population.
Background In paediatric cardiac surgery, there has been a paradigm shift in perioperative management from a slow wean of mechanical ventilation in the intensive care unit (ICU), to “ultra fast-track” anaesthesia with early extubation (EE) in theatre to promote a faster recovery. Adults with congenital heart disease (ACHD) have multiple risk factors for prolonged intubation, including a greater proportion of re-do interventions, more co-morbidities and metabolic differences leading to slower emergence from anaesthesia. As a result, EE remains unproven and has not been widely adopted and in this patient group. Aim To assess the effects of EE on post-operative haemodynamics, hospital stay and associated healthcare costs. Methods Data were collected on ACHD patients, who underwent cardiac surgery in a high-volume tertiary centre between 2012 and 2018. Propensity score matching (1:1 or 2:1 where possible) was performed using the following variables: age, sex, body mass index, CHD complexity, functional class, length of surgery, systemic ventricular function, procedure-specific risk (adult congenital heart score; ACHS), urgent versus elective procedure, active endocarditis, pulmonary hypertension and renal dysfunction. Results 614 procedures were performed during the study period. After matching, 87 (14.2%) patients receiving EE were compared to 164 patients who received conventional care (CC). The overall complication rate was low, with no difference between the EE and CC groups (8.0% vs. 9.1%, p=0.77), and a very low reintubation rate (<1%). EE patients had a significantly shorter post-operative hospital length of stay in ICU and the high dependency unit (HDU; 48 [43–51] vs. 50 [47–69] hours, p<0.0001). EE patients required less inotropic & vasopressor support, as demonstrated by a lower Vasoactive-Inotropic Score (VIS) compared to patients following NEE (median VIS 0.5 [0.0–1.8] vs. 2.0 [0.0–3.5], p<0.0001). The total fluid balance by the third post-operative day was more positive after CC than EE (1177±737mL vs. 927±780mL, p=0.004). Finally, lower combined ICU and HDU costs were incurred by EE compared with CC (£3.9K[2.8–4.2K] vs. £4.2K[3.9–6.3K], p<0.0001). Conclusion In ACHD patients undergoing cardiac surgery, including complex and redo procedures, EE was safe, associated with a shorter ITU and HDU stay and lower hospital costs.
