Abstract Introduction: Patients submitted to cardiovascular surgery present motor and respiratory complications mainly due to high surgery manipulation and the use of mechanical ventilation. Reducing the weaning start time and disconnecting patient's ventilation system prematurely can decrease the pulmonary complications and hospitalization time. Motor complications are the most relevant as they have a direct effect on functional independence provoked by immobility time. Objectives : Identify if mechanical ventilation time has an impact on functional capacity on patients submitted to cardiac surgery in order to contribute to the establishment of reliable evidence to practice through this patient's profile. Materials and methods : Original articles were analyzed, published between 2000 and 2014, which focused on the influence of mechanical ventilation time concerning the functional independence on patients submitted to cardiac surgery, contained in the following electronic database: Scielo, BIREME (LILACS), PubMed e CAPES. Results : It was observed that the length of stay in the intensive care unit in cardiac surgery was influenced directly by CPB, VM and pulmonary dysfunction. Functional independence was compromised in patients with longer duration of mechanical ventilation, postoperative pain and prolonged bed rest. It was also found that there is no consensus on the protocol for improved functional capacity. Conclusion : There is a functional decline in patients undergoing cardiac surgery, especially those at increased length of stay in mechanical ventilation, reflecting a direct and negative impact on their functional independence and quality of life.

Abstract Abstract Background : The use of dexmedetomidine for sedation post-cardiac surgery is controversial compared to the use of propofol. Methods : A computerized search on Medline, EMBASE, Web of Science, and Agency for Healthcare Research and Quality databases was performed for up to July 2019. Trials evaluating the efficacy of dexmedetomidine versus propofol in the postoperative sedation of cardiac surgery patients were selected. Primary study outcomes were classified as time-dependent (mechanical ventilation time; time to extubation; length of stay in the intensive care unit and the hospital) and non-time dependent (delirium, bradycardia, and hypotension). Results : Our final analysis included 11 RCTs published between 2003 and 2019 and involved a total of 1184 patients. Time to extubation was significantly reduced in the dexmedetomidine group (Standardized Mean Difference (SMD) = -0.61, 95% Confidence Interval (CI): -1.06 to -0.16, p=0.008), however no difference in mechanical ventilation time was observed (SMD= -0.72, 95% CI: -1.60 to 0.15, N.S.). Moreover, the dexmedetomidine group showed a significant reduction in Intensive Care Unit length of stay (SMD= -0.70, 95% CI: -0.98 to -0.42, p=0.0005) this did not translate into a reduced hospital length of stay (SMD= -1.13, 95% CI: -2.43 to 0.16, N.S). For non-time dependent factors: incidence of delirium was unaffected between groups (OR: 0.68, 95% CI: 0.43 to 1.06, N.S.), while the propofol group of patients had higher rates of bradycardia (OR: 3.39, 95% CI: 1.20 to 9.55, p=0.020) and hypotension (OR: 1.68, 95% CI: 1.09 to 2.58, p=0.017). Conclusion : Despite the ICU time advantages afforded by dexmedetomidine over propofol, the former does not contribute to an overall reduction in hospital length of stay or an overall improvement in postoperative outcomes for heart valve surgery and CABG patients. Time-dependent outcomes confounded by several factors including variability in staff, site-protocols, and complication rates between individual surgical cases. Keywords: dexmedetomidine; propofol; cardiac surgery; postoperative sedation.

Abstract BACKGROUND: The efficacy and safety of dexmedetomidine in sedation for postoperative cardiac surgeries is controversial when compared to propofol. METHODS: A computerized search of Medline, Cochrane and Google Scholar databases was performed through August 2018. Studies evaluating the efficacy of dexmedetomidine versus propofol in the sedation of postoperative cardiac surgery patients were searched. The main study outcomes were divided into time dependent (mechanical ventilation time; time to extubation; length of stay in the intensive care unit and in the hospital) and non-time dependent (delirium, bradycardia, and hypotension). RESULTS: The final analysis included 15 trials with a total of 2488 patients. Time to extubation was significantly reduced in the dexmedetomidine group (Standardized Mean Difference (SMD) = -0.54, 95% Confidence Interval (CI): -0.89 to -0.18, p=0.003), as well as mechanical ventilation time (SMD= -0.71, 95% CI: -1.19 to -0.23, p=0.004). Moreover, the dexmedetomidine group showed a significant reduction in Intensive Care Unit length of stay (SMD= -0.38, 95% CI: -0.60 to -0.16, p=0.001) and hospital length of stay (SMD= -0.39, 95% CI: -0.60 to -0.19, p<0.001). However, these time dependent outcomes could have been affected by several confounding factors, thus limiting the value of these results. Incidence of delirium was reduced in the dexmedetomidine group (OR: 0.47, 95% CI: 0.29 to 0.76, p=0.002), while this group of patients had higher rates of bradycardia (OR: 2.52, 95% CI: 1.15 to 5.55, p=0.021). There was no significant difference in rates of hypotension between the two groups. CONCLUSION: Despite the apparent time advantages afforded by dexmedetomidine over propofol, the former does not show particular overall improvements in postoperative care of cardiac surgery patients. Since time dependent outcomes seems to be affected by several confounding factors, more efforts are needed to analyze factors that could affect sedation in post-cardiac surgery patients and choose unbiased outcomes. KEYWORDS: Dexmedetomidine; propofol; cardiac surgery; postoperative sedation.

Abstract Purpose: To evaluate the effect of low-dose exogenous surfactant therapy on infants suffering acute respiratory distress syndrome (ARDS) after cardiac surgery. Materials and methods: We conducted a retrospective case-control study of the archive data of infants diagnosed with ARDS after cardiac surgery and admitted to pediatric cardiac surgical intensive care unit (PICU). A case was defined as a patient that received surfactant and standard therapy; a control was defined as a patient that underwent standard therapy. Controls were identified by matching patients based on age(±30d), weight(±3kg), risk adjustment congenital heart surgery-1 (RACHS-1), and initial ratio of partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2) (±10). Outcome variables namely oxygenation indices (OI), ventilation index (VI), mechanical ventilation time and PICU time were compared.Results: Forty-four patients, 22 who received surfactant (surfactant group) and 22 who did not (control group) were analyzed. Surfactant group obtained a significant improvement on OI (13.9 vs 5.62; p=0.000) and VI (42.0 vs 22.4; p=0.000) in 6 hours, while control group got no improvement on OI (13.2 vs 11.5; p=0.065) and VI (40.2 vs 36.4; p=0.100). Compared with control group, surfactant group had shorter ventilation time (133.6h vs 218.4h; p=0.000) and PICU time (10.7d vs 17.5d; p=0.001). Infants in surfactant group under 3 months benefit more from OI and VI than infants over 3 months.Conclusions: In congenital heart disease infants with post-surgery ARDS, low-dose exogenous surfactant treatment could prominently improve oxygenation and reduced mechanical ventilation time and PICU time. And the improvement of oxygenation is more effective for infants under 3 months.

Abstract The aim of this study was to report the respiratory management of a cohort of infants admitted to a Pediatric Intensive Care Unit (PICU) over a 7-year period due to severe burn injury and the potential benefits of noninvasive ventilation (NIV). A retrospective review of all pediatric patients admitted to PICU between 2009 and 2016 was conducted. From 2009 to 2016, 118 infants and children with burn injury were admitted to our institution (median age 16 months [IQR = 12.2–20]); 51.7% of them had face burns, 37.3% underwent tracheal intubation, and 30.5% had a PICU stay greater than 7 days. Ventilated patients had a longer PICU stay (13 days [IQR = 8–26] vs 4.5 days [IQR = 2–13]). Both ventilation requirement and TBSA% correlated with PICU stay (r = .955, p < .0001 and r = .335, p = .002, respectively), while ventilation was best related in those >1 week (r = .964, p < .0001 for ventilation, and r = −.079, p = .680, for TBSA%). NIV was introduced in 10 patients, with the aim of shorten the invasive ventilation requirement. As evidenced in our work, mechanical ventilation is frequently needed in burned children admitted to PICU and it is one of the main factors influencing PICU length of stay. No difference was found in terms of PICU length of stay and invasive mechanical ventilation time between children who underwent NIV and children who did not, despite children who underwent NIV had a larger burn surface. NIV can possibly shorten the total invasive ventilation time and related complications.

Background The transfusion of erythrocytes that have been stored for long periods of time can produce visceral ischemia and favor the acquisition of postsurgical infections. To estimate the role of the duration of storage of erythrocytes on morbidity in cardiac surgery, we performed an observational study. Methods All patients (n = 897) undergoing cardiac surgery during three consecutive years were included. Morbidity (main outcome measure) was evaluated by means of four surrogate measures: duration of stay in the intensive care unit longer than 4 days, mechanical ventilation time longer than 1 day, perioperative myocardial infarction rate, and severe postoperative infection rate. The mean duration of storage of all erythrocytes transfused and the duration of storage of the oldest unit transfused were used as storage variables. Results After considering multiple confounding variables related to patient severity, illness, and surgical difficulty, the duration of storage of erythrocytes was found to be associated neither with a more prolonged stay in the intensive care unit or mechanical ventilation time nor with increased rates of perioperative infarction, mediastinitis, or sepsis. However, each day of storage of the oldest unit was associated with an increment of the risk of pneumonia of 6% (95% confidence interval, 1-11; P = 0.018). The cutoff point of maximum sensitivity and specificity (54.8 and 66.9%) associated with a greater risk for pneumonia corresponded to 28 days of storage for the oldest unit (odds ratio, 2.74; 95% confidence interval, 1.18-6.36; P = 0.019). Conclusions Prolonged storage of erythrocytes does not increase morbidity in cardiac surgery. However, storage for longer than 28 days could be a risk factor for the acquisition of nosocomial pneumonia.

Background and Aims: Appropriate use of sedatives and analgesics is essential to keep critically ill patients comfortable and to prevent prolonged mechanical ventilation time and length of stay in ICU. Aim of this study was to analyse the long-term effect of an algorithm-based individual analgesic-sedative protocol on mechanical ventilation time and ICU length of stay in critically ill patients after sudden cardiac arrest due to ST-elevated myocardial infarction. Subject and Methods: We examined a total of 109 patients before and after implementation of an algorithm-based sedation management. Our sedation protocol included individual defined sedation goals achieved by standardized sedation strategies. Mechanical ventilation time and ICU length of stay were analysed for three groups of patients: before and after the intervention and in the long-term follow-up. Results: We observed shorter median mechanical ventilation time and ICU length of stay in the interventional and longterm follow-up group compared to the standard-care group without statistical significance. Conclusion: Our results demonstrate a long-term reduction of mechanical ventilation time and ICU length of stay achieved by implementation of an individual sedation management. This suggests sedation guidelines as effective tools to reduce the mechanical ventilation time and ICU length of stay in patients after sudden cardiac arrest in ST-elevated myocardial infarction. Investigations with a larger patient number and higher statistical power are required to confirm these findings.

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.
