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 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.

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 Objectives: The aim of this study was to investigate the association between obesity and 28-day mortality, duration of invasive mechanical ventilation and length of stay at the Intensive Care Unit (ICU) and hospital in patients admitted to the ICU for SARS-CoV-2 pneumonia. Materials and Methods: This was a retrospective observational cohort study in patients admitted to the ICU for SARS-CoV-2 pneumonia, in a single Dutch center. The association between obesity (body mass index > 30 kg/m2) and 28-day mortality, duration of invasive mechanical ventilation and length of ICU and hospital stay was investigated. Results: In 121 critically ill patients, pneumonia due to SARS-CoV-2 was confirmed by RT-PCR. Forty-eight patients had obesity (33.5%). The 28-day all-cause mortality was 28.1%. Patients with obesity had no significant difference in 28-day survival in Kaplan–Meier curves (log rank p 0.545) compared with patients without obesity. Obesity made no significant contribution in a multivariate Cox regression model for prediction of 28-day mortality (p = 0.124), but age and the Sequential Organ Failure Assessment (SOFA) score were significant independent factors (p < 0.001 and 0.002, respectively). No statistically significant correlation was observed between obesity and duration of invasive mechanical ventilation and length of ICU and hospital stay. Conclusion: One-third of the patients admitted to the ICU for SARS-CoV-2 pneumonia had obesity. The present study showed no relationship between obesity and 28-day mortality, duration of invasive mechanical ventilation, ICU and hospital length of stay. Further studies are needed to substantiate these findings.

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 Objective To identify the factors associated with the intra-hospital mortality in patients with traumatic brain injury (TBI) admitted to intensive care unit (ICU). Methods The sample included patients with TBI admitted to the ICU consecutively in a period of one year. It was defined as variables the epidemiological characteristics, factors associated with trauma and variables arising from clinical management in the ICU. Results The sample included 87 TBI patients with a mean age of 28.93 ± 12.72 years, predominantly male (88.5%). The intra-hospital mortality rate was of 33.33%. The initial univariate analysis showed a significant correlation of intra-hospital death and the following variables: the reported use of alcohol (p = 0.016), hemotransfusion during hospitalization (p = 0.036), and mechanical ventilation time (p = 0.002). Conclusion After multivariate analysis, the factors associated with intra-hospital mortality in TBI patients admitted to the intensive care unit were the administration of hemocomponents and mechanical ventilation time.

Abstract Introduction:Patients undergoing cardiac surgery are among the most common recipients of allogenic red blood cell (RBC) transfusions. However, whether restrictive RBC transfusion strategies for cardiac surgery achieve a similar clinical outcome in comparison with liberal strategies remains unclear. Methods:We searched PubMed, Embase, the Cochrane Collaboration Central Register of Controlled Trials, and conference proceedings from inception to December 2017 for all randomized trials (RCTs). The primary outcome was mortality. Secondary outcomes were stroke, respiratory morbidity, renal morbidity, infections, myocardial infarction (MI), cardiac arrhythmia, gut morbidity, reoperation, intensive care unit (ICU) length of stay (hours), and hospital length of stay (days). We calculated the risk ratios (RR) and weighted mean difference (MD) for the clinical outcomes using a random-effects model. Results:We included 9 RCTs with a total of 9,005 patients. There was no significant difference in mortality between groups (RR 1.03; 95% CI 0.74-1.45; P=0.86). In addition, there were no significant differences between groups in the clinical outcomes of infections (RR 1.09; 95% CI 0.94-1.26; P=0.26), stroke (RR 0.98; 95% CI 0.72-1.35; P=0.91), respiratory morbidity (RR 1.05; 95% CI 0.89-1.24; P=0.58), renal morbidity (RR 1.02; 95% CI 0.94-1.09; P=0.68), myocardial infarction (RR 1.00; 95% CI 0.80-1.24; P=0.99), cardiac arrhythmia (RR 1.05; 95% CI 0.88-1.26; P=0.56), gastrointestinal morbidity (RR 1.93; 95% CI 0.81-4.63; P=0.14), or reoperation (RR 0.90; 95% CI 0.67-1.20; P=0.46). There was a significant difference in the intensive care unit length of stay (hours) (MD 4.29; 95% CI: 2.19-6.39, P<0.01) favoring the liberal group. However, there was no significant difference in the hospital length of stay (days) (MD 0.15; 95% CI -0.18-0.48; P=0.38). Conclusion:This meta-analysis showed that restrictive strategies for RBC transfusion are as safe as liberal strategies in patients undergoing cardiac surgery. Key points: Restrictive strategies for red blood cell transfusion are as safe as liberal approaches in patients undergoing cardiac surgery. Longer duration of stay in the intensive care unit is more common in patients managed with a restrictive transfusion approach. However, the overall hospital length of stay appeared to be similar between both groups. Further studies are needed to ascertain threshold triggers for RBC transfusion. Figure. Figure.

Background: Early mobilization of the Intensive Care Unit (ICU) patients improves muscle strength and functional capacity. It has been demonstrated that prevents Intensive Care Unit Acquired Weakness (ICUAW) and accelerates ICU discharge. However, data on mobilization early after cardiac surgery are inadequate. This study aimed to record early mobilization and investigates the association with ICU findings in cardiac surgery patients.Material and Methods: In this observational study, 165 patients after cardiac surgery were enrolled. Of these, 159 were assessed for early mobilization and mobilization status during ICU stay. Mobilization practices were recorded from 1st post ICU admission and every 48 h until 7th day. The duration of mechanical ventilation (MV) support, ICU length of stay and clinical outcome were recorded from medical records registration. Results: Early mobilization consisted of active and passive limb mobilization, sitting in bed and transferring from bed to chair. The proportion of patients mobilized, was 18% (n = 29/159) on day 1, 53% (n = 46/87) on day 3, 54% (n = 22/41) on day 5 and 62% (n = 15/24) on day 7. ICU length of stay was reduced for mobilized patients (n = 29) on day 1 compared to non-mobilized ones (24 ± 10 vs 47 ± 73 h respectively, P = 0.001). The duration of MV was shorter in mobilized patients on day 3 (n =46) compared to bedridden, (18 ± 9 vs 23 ± 30 h respectively, P = 0.01).Conclusions: Early mobilization after cardiac surgery was found to be low with a significant trend to increase over ICU stay. It is also associated with a reduced duration of MV and ICU length of stay.

Abstract Background Postoperative delirium (POD) is a relevant and underdiagnosed complication after cardiac surgery that is associated with increased intensive care unit (ICU) and hospital length of stay (LOS). The aim of this subgroup study was to compare the frequency of tested POD versus the coded International Statistical Classification of Diseases and Related Health Problems (ICD) diagnosis of POD and to evaluate the influence of POD on LOS in ICU and hospital. Methods 254 elective cardiac surgery patients (mean age, 70.5 ± 6.4 years) at the University Hospital Bonn between September 2018 and October 2019 were evaluated. The endpoint tested POD was considered positive, if one of the tests Confusion Assessment Method for ICU (CAM-ICU) or Confusion Assessment Method (CAM), 4 'A's Test (4AT) or Delirium Observation Scale (DOS) was positive on one day. Results POD occurred in 127 patients (50.0%). LOS in ICU and hospital were significantly different based on presence (ICU 165.0 ± 362.7 h; Hospital 26.5 ± 26.1 days) or absence (ICU 64.5 ± 79.4 h; Hospital 14.6 ± 6.7 days) of POD (p < 0.001). The multiple linear regression showed POD as an independent predictor for a prolonged LOS in ICU (48%; 95%CI 31–67%) and in hospital (64%; 95%CI 27–110%) (p < 0.001). The frequency of POD in the study participants that was coded with the ICD F05.0 and F05.8 by hospital staff was considerably lower than tests revealed by the study personnel. Conclusion Approximately 50% of elderly patients who underwent cardiac surgery developed POD, which is associated with an increased ICU and hospital LOS. Furthermore, POD is highly underdiagnosed in clinical routine.
