Measurement of ventilatory reserve as an indicator for early extubation after cardiac operation

Background: Early extubation is performed either in the operating room or in the cardiovascular intensive care unit during the first 24 postoperative hours; however, altitude might possibly affect the process. The aim of this study is the evaluation of early extubation feasibility of patients undergoing congenital heart surgery in a center located at 2,691 m (8,828 ft.) above sea level. Material and Methods: Patients undergoing congenital heart surgery, from August 2012 through December 2018, were considered for early extubation. The following variables were recorded: weight, serum lactate, presence or not of Down syndrome, optimal oxygenation and acid–base status according to individual physiological condition (biventricular or univentricular), age, bypass time, and ventricular function. Standardized anesthetic management with dexmedetomidine–fentanyl–rocuronium and sevoflurane was used. If extubation in the operating room was considered, 0.08 mL/kg of 0.5% ropivacaine was injected into the parasternal intercostal spaces bilaterally before closing the sternum. Results: Four hundred seventy-eight patients were operated and 81% were early extubated. Mean pre- and postoperative SaO2 was 92% and 98%; postoperative SaO2 for Glenn and Fontan procedures patients was 82% and 91%, respectively. Seventy-three percent of patients who underwent Glenn procedure, 89% of those who underwent Fontan procedure (all nonfenestrated), and 85% with Down syndrome were extubated in the operating room. Reintubation rate in early extubated patients was 3.6%. Conclusion: Early extubation is feasible, with low reintubation rates, at 2,691 m (8,828 ft.) above sea level, even in patients with single ventricle physiology.

Abstract Background Usefulness of noninvasive ventilation (NIV) in weaning patients with non-hypercapnic hypoxemic acute respiratory failure (hARF) is unclear. The study aims to assess in patients with non-hypercapnic hARF, the efficacy of NIV after early extubation, compared to standard weaning. Methods In this individual patient data meta-analysis, we searched EMBASE, Medline and Cochrane Central Register of Controlled Trials to identify potentially eligible randomized controlled trials published from database inception to October 2020. To be eligible, studies had to include patients treated with NIV after early extubation and compared to conventional weaning in adult non-hypercapnic hARF patients. Anonymized individual patient data from eligible studies were provided by study investigators. Using one-step and two-step meta-analysis models we tested the difference in total days spent on invasive ventilation. Results We screened 1605 records. Six studies were included in quantitative synthesis. Overall, 459 participants (mean [SD] age, 62 [15] years; 269 [59%] males) recovering from hARF were included in the analysis (233 in the intervention group and 226 controls). Participants receiving NIV had a shorter duration of invasive mechanical ventilation compared to control group (mean difference, − 3.43; 95% CI − 5.17 to − 1.69 days, p < 0.001), a shorter duration of total days spent on mechanical ventilation (mean difference, − 2.04; 95% CI − 3.82 to − 0.27 days, p = 0.024), a reduced risk of ventilatory associated pneumonia (odds ratio, 0.24; 95% CI 0.08 to 0.71, p = 0.014), a reduction of time spent in ICU (time ratio, 0.81; 95% CI 0.68 to 0.96, p = 0.015) and in-hospital (time ratio, 0.81; 95% CI 0.69 to 0.95, p = 0.010), with no difference in ICU mortality. Conclusions Although primary studies are limited, using an individual patient data metanalysis approach, NIV after early extubation appears useful in reducing total days spent on invasive mechanical ventilation. Trial registration The protocol was registered to PROSPERO database on 12/06/2019 and available at PROSPERO website inserting the study code i.e., CRD42019133837.
