RESUMO

BACKGROUND: Compared with coronary artery bypass grafting surgery, data regarding postoperative delirium are scant in valvular open-heart surgery. Therefore, the goal of this retrospective study was to investigate the incidence, preoperative risk factors, and early outcomes of delirium in a large group of patients undergoing valvular open-heart surgery. METHODS: In 13,229 patients with isolated valvular or combined valvular and bypass surgery, the incidence of postoperative delirium was assessed until discharge. Independent risk factors of delirium were evaluated by multivariable logistic regression analysis. Moreover, we assessed the multivariable-adjusted risk of prolonged intensive care unit (ICU) stay (>48 hours) and in-hospital mortality in patients with delirium. RESULTS: Overall, the incidence of postoperative delirium was 8.4%. The incidence in patients experiencing a postoperative stroke or seizure was 23.1 and 29.7%, respectively. Twelve preoperative risk factors, mostly nonmodifiable, were independently associated with the risk of delirium, including advanced age, renal impairment, stroke, the need for emergency surgery, and severe preoperative anemia (hemoglobin < 9 g/dL). Postoperative delirium was associated with an adjusted odds ratio (OR) of prolonged ICU stay of 9.48 (95% confidence interval [CI]: 7.96-11.30). Adjusted in-hospital mortality was, however, significantly lower in patients with delirium versus patients without delirium (OR, 0.56; 95% CI: 0.38-0.83). CONCLUSION: In valvular open-heart surgery, postoperative delirium is a frequent neurological complication that is associated with other postoperative neurological complications and several, mostly nonmodifiable, preoperative risk factors. Although postoperative delirium was associated with a significantly increased risk of prolonged ICU stay, this did not translate into an increased short-term mortality.

RESUMO

Extracorporeal membrane oxygenation (ECMO) is increasingly used in COVID-19-related pulmonary failure and the number of patients recovering from COVID-19 is growing. Here, we assess survival and recovery 6 months after ECMO for COVID-19. From April 2020 to September 2021, n = 60 (60.5 [51.0-65.0] years, 23.3% female) were treated with venovenous/venoarterial ECMO for COVID-19. 41.7% were weaned off ECMO, survival-to-discharge was 40.0% (n = 24). Age (63.0 [60.0-66.8] vs. 55.0 [43.8-60.0] years, p < 0.001), vasoactive support (97.2% vs . 75.0%, p = 0.013), and pre-ECMO SOFA scores (13.0 [12.0-14.8] vs. 12.0 [10.0-13.8] p = 0.036) correlated with nonsurvival. All patients aged >65 years, with histories of neoplasia, immunocompromise, chronic renal failure, or frailty died. After 6 months, 20 were alive (6-month survival 33.3%, survival conditioned on survival-to-discharge 83.3%), with follow-up in 19. 57.9% showed no relevant, 26.3% moderate, 15.8% severe deficits. Cardiopulmonary status was satisfactory (mMRC level: 84.2% ≤2). 73.7% were independent in daily life. Cognitive impairments were frequent (52.6%). 26.3% showed moderate depression, 15.8% posttraumatic stress disorder. Social and work life were considerably affected. Extracorporeal membrane oxygenation thus can serve as salvage therapy in COVID-19, but advanced age, immunocompromise, histories of neoplasia, and frailty must be considered as relative contraindications. Age, vasoactive support, and SOFA scores assist discriminating in daily practice. Deficits after 6 months are substantial, and efforts need to focus on long-term recovery.
