Objectives: To synthesize data on outcomes related to patients, family members, and ICU professionals by comparing flexible versus restrictive visiting policies in ICUs. Data Sources: Medline, Scopus, and Web of Science. Study Selection: Observational and randomized studies comparing flexible versus restrictive visiting policies in the ICU and evaluating at least one patient-, family member–, or ICU staff–related outcome. Data Extraction: Duplicate independent review and data abstraction. Data Synthesis: Of 16 studies identified for inclusion, seven were meta-analyzed. Most studies were rated as having a moderate risk of bias. Among patients, flexible visiting policies were associated with reduced frequency of delirium (odds ratio, 0.39; 95% CI, 0.22–0.69; I 2 = 0%) and lower severity of anxiety symptoms (mean difference, –2.20; 95% CI, –3.80 to –0.61; I 2 = 71%). Flexible visiting policies were not associated with increased risk of ICU mortality (odds ratio, 0.71; 95% CI, 0.38–1.36; I 2 = 86%), ICU-acquired infections (odds ratio, 0.98; 95% CI, 0.68–1.42; I 2 = 11%), or longer ICU stay (mean difference, –0.26 d; 95% CI, –0.57 to 0.05; I 2 = 54%). Among family members, flexible visiting policies were associated with greater satisfaction. Among ICU professionals, flexible visiting policies were associated with higher burnout levels. Conclusions: Flexible ICU visiting hours have the potential to reduce delirium and anxiety symptoms among patients and to improve family members’ satisfaction. However, they may be associated with an increased risk of burnout among ICU professionals. These conclusions are based on few studies, with small samples and moderate risk of bias.

Fluids are considered the cornerstone of therapy for many shock states, particularly states that are associated with relative or absolute hypovolemia. Fluids are also commonly used for many other purposes, such as renal protection from endogenous and exogenous substances, for the safe dilution of medications and as “maintenance” fluids. However, a large amount of evidence from the last decade has shown that fluids can have deleterious effects on several organ functions, both from excessive amounts of fluids and from their non-physiological electrolyte composition. Additionally, fluid prescription is more common in patients with systemic inflammatory response syndrome whose kidneys may have impaired mechanisms of electrolyte and free water excretion. These processes have been studied as separate entities (hypernatremia, hyperchloremic acidosis and progressive fluid accumulation) leading to worse outcomes in many clinical scenarios, including but not limited to acute kidney injury, worsening respiratory function, higher mortality and higher hospital and intensive care unit length-of-stays. In this review, we synthesize this evidence and describe this phenomenon as fluid and electrolyte overload with potentially deleterious effects. Finally, we propose a strategy to safely use fluids and thereafter wean patients from fluids, along with other caveats to be considered when dealing with fluids in the intensive care unit.

Background: Awake prone positioning has been widely used in patients with COVID‐19 respiratory failure to avoid intubation despite limited evidence. Our objective was to evaluate if prone positioning is associated with a reduced intubation rate when compared to usual care.Methods: This was a retrospective cohort study in the emergency department of a large quaternary hospital in Sao Paulo. We retrieved data from all admitted patients in need of oxygen supplementation (>3 L/min) and tachypnea (>24 ipm) from March 1 to April 30, 2020, excluding those who had any contraindication to the prone position or who had an immediate need for intubation. The primary endpoint was endotracheal intubation up to 15 days. Secondary outcomes included a 6‐point clinical outcome ordinal scale, mechanical ventilation–free days, admission to the intensive care unit, and need of hemodialysis and of vasoactive drugs, all assessed at or up to 15 days. We analyzed unadjusted and adjusted effect estimates with Cox proportional hazards models, logistic regression, quantile regression, and sensitivity analyses using propensity score models.Results: Of 925 suspected COVID‐19 patients admitted off mechanical ventilation, 166 patients fulfilled inclusion and exclusion criteria: 57 were exposed to prone positioning and 109 to usual care. In the intervention group, 33 (58%) were intubated versus 53 (49%) in the control group. We observed no difference in intubation rates in the univariate analysis (hazard ratio = 1.21, 95% confidence interval [CI] = 0.78 to 1.88, p = 0.39) nor in the adjusted analysis (hazard ratio = 0.90, 95% CI = 0.55 to 1.49, p = 0.69). Results were robust to the sensitivity analyses. Secondary outcomes did not differ between groups.Conclusions: Awake prone positioning was not associated with lower intubation rates. Caution is necessary before widespread adoption of this technique, pending results of clinical trials.

Utilization of extracorporeal membrane oxygenation (ECMO) has increased worldwide, but its use remains restricted to severely ill patients, and few referral centers are properly structured to offer this support. Inter-hospital transfer of patients on ECMO support can be life-threatening. In this study, we report a single-center experience and a systematic review of the available published data on complications and mortality associated with ECMO transportation. We reported single-center data regarding complications and mortality associated with the transportation of patients on ECMO support. Additionally, we searched multiple databases for case series, observational studies, and randomized controlled trials regarding mortality of patients transferred on ECMO support. Results were analyzed independently for pediatric (under 12 years old) and adult populations. We pooled mortality rates using a random-effects model. Complications and transportation data were also described. A total of 38 manuscripts, including our series, were included in the final analysis, totaling 1481 patients transported on ECMO support. A total of 951 patients survived to hospital discharge. The pooled survival rates for adult and pediatric patients were 62% (95% CI 57–68) and 68% (95% CI 60–75), respectively. Two deaths occurred during patient transportation. No other complication resulting in adverse outcome was reported. Using the available pooled data, we found that patient transfer to a referral institution while on ECMO support seems to be safe and adds no significant risk of mortality to ECMO patients.
