Unpublished:     FLORALI Study

In 310 patients with acute hypoxaemic respiratory failure (PaO2 /FiO2 < 300 mmHg), standard oxygen therapy (n=94) was compared with high flow nasal oxygen (n=106) and with a combination of noninvasive ventilation (minimum 8 hours per day) and HFNO (n=110). The authors found:

  1. most patients had either community-acquired pneumonia (≈60%) or hospital-acquired pneumonia (≈10%)
  2. 77% had a PaO2 /FiO2 < 200 mmHg
  3. no difference in the requirement for invasive mechanical ventilation (1° outcome)
    • SOT 46.8 % vs HFNO 37.7% vs NIV/HFNO 50%; p=0.17
      • reduced requirement for invasive mechanical ventilation in those with a PaO2 /FiO2 < 200 mmHg (n=238)
      • SOT 52.7 % vs HFNO 34.9% vs NIV/HFNO 58%; p=0.009
  4. reduced 
    • ICU mortality
      • SOT 19.1 % vs HFNO 11.3 % vs NIV/HFNO 24.5 %; p<0.05

      • reoperations (5.6% vs 15.7%; P = 0.049)
    • no statistically significant differences in
      • overall fluid administration
      • overall complications (40% vs 41%)
        • relative risk 0.99; 95% CI 0.67 to 1.44; P = 0.397
      • length of stay (11.5 [8-15] vs 10.5 [8-16]; P = 0.874)
      • time to first flatus (62 hours [40-76] vs 72 hours [48-96]; P = 0.180)

JAMA: Red Cell Management in Traumatic Brain Injury

Robertson and colleagues, using a factorial design, compared intravenous erythropoietin (500 IU/kg per dose, n=102) with saline (n=98), plus red cell transfusion at a threshold of either 7 g/dL (n=99) or 10 g/dL (n=101), on Glasgow Outcome Scale score at 6 months postinjury, in 200 patients within 6 hours of closed head injury and unable to follow commands. Erythropoietin or placebo was initially dosed daily for 3 days and then weekly for 2  weeks (group 1, n = 74). The protocol was subsequently amended to (I think, it's remarkably poorly described) a single erythropoietin dose, possibly followed by further doses at 1 and 2 weeks if the patient was still in ICU (n=126). The authors found:

  1. no interaction between erythropoietin and hemoglobin transfusion threshold
  2. no statistical improvement on favorable outcome rate (dichotomized as favorable (good recovery and moderate disability) or unfavorable (severe disability, vegetative, or dead))
    • between placebo and erythropoietin
      • placebo: 38.2%; 95% CI 28.1% to 49.1%
      • erythropoietin
        • first dosing regimen:  48.6%; 95% CI 31.4% to 66.0%, P =0.13
        • second dosing regimen: 29.8%; 95% CI 18.4% to 43.4%; P  < 0.001
    • between haemoglobin transfusion thresholds
      • 7 g/dL:  42.5%
      • 10 g/dL: 33.0%
        • 95% CI for the difference −0.06 to 0.25, P = 0.28
  3. the 10 g/dL transfusion threshold was associated with a
    • higher incidence of thromboembolic events (21.8% vs 8.1%; odds ratio 0.32, 95% CI 0.12 to 0.79; P = 0.009)

Conclusion: In a two centre, factorial, randomized controlled trial, in patients with closed head injury, neither erythropoietin administration nor red blood cell transfusion maintaining a haemoglobin level of ≥10 g/dL versus ≥ 7 g/dL, were statistically associated with improved outcomes, with the higher haemoglobin level associated with more thrombotic events.

New Engl J Med:  PEEP in General Anaesthesia

The PROVE Network Investigators compared high PEEP (median 12 cmH20) plus recruitment maneuvres (n=447) with low PEEP (median 2 cmH20) without recruitment manuevres (n=453) in 900 patients undergoing open abdominal surgery, ventilated with 8 ml/kg and at high risk for postoperative pulmonary complications, and found no difference in post-operative complications (high PEEP 40% vs low PEEP 39%, RR1·01; 95% CI 0·86 to1·20; p=0·86), but increased hypotension with higher PEEP, requiring more vasopressor therapy.

New Engl J Med:  Long-Acting Gram Positive Antibacterial Therapy

Boucher et al pooled two identically designed, industry funded, noninferiority trials, and found once-weekly IV dalbavancin (a long-acting lipoglycopeptide antibiotic active against gram positive bacteria, n=659) was non-inferior to twice-daily IV vancomycin followed by oral linezolid (n=653) for the treatment of acute bacterial skin and skin-structure infection, with no difference in early clinical response indicating treatment success (79.7% vs 79.8%, respectively; weighted difference, −0.1%; 95% CI−4.5 to 4.2%), or side effects. Individual study analyses yielded similar results, as did pooled analysis of clinical status at end of therapy.

New Engl J Med:  Long-Acting Gram Positive Antibacterial Therapy

Corey and colleagues found a single dose of IV oritavancin (a long-acting lipoglycopeptide with bactericidal activity against gram-positive bacteria, n=475) was non-inferior to a regimen of twice daily IV vancomycin for 7 to 10 days (n=479) in 954 adults with acute bacterial skin and skin-structure infections, for three main outcomes:

  • spreading or reduction in lesion size, absence of fever, and no need for administration of a rescue antibiotic after 48 to 72 hours (82.3% vs 78.9%, respectively;  95% CI for difference −1.6 to 8.4%)
  • clinical cure 7 to 14 days after the end of treatment, as determined by a study investigator (79.6% vs 80.0%, 95% CI for difference −5.5 to 4.7%)
  • reduction in lesion size of 20% or more after 48 to 72 hours (86.9% vs 82.9%, 95% CI for difference −0.5 to 8.6%)

New England Journal of Medicine:     Perioperative Aspirin & Clonidine

Devereaux and colleagues performed an international, multicentre, blinded, randomized, controlled, 2-by-2 factorial trial permitting separate evaluation of low-dose clonidine versus placebo and low-dose aspirin versus placebo in 10,010 patients with, or at risk for, atherosclerotic disease who were undergoing noncardiac surgery.

In the aspirin arm, patients were statified by those already receiving aspirin (continuation stratum, n=4382) or not (initiation stratum, n=5628), to the perioperative administration of aspirin or placebo. Patients started taking aspirin (at a dose of 200 mg) or placebo just before surgery and continued it daily (at a dose of 100 mg) for 30 days in the initiation stratum and for 7 days in the continuation stratum, after which patients resumed their regular aspirin regimen. The authors found:

  1. no difference in the primary endpoint, a composite of death or nonfatal myocardial infarction at 30 days
    • aspirin group: 7.0% (351/4998) versus placebo group: 7.1% (355/5012)
    • hazard ratio in the aspirin group 0.99, 95% CI 0.86 to 1.15; P=0.92
  2. increased major bleeding with aspirin
    • 4.6% vs 3.8%, hazard ratio 1.23; 95% CI 1.01 to 1.49; P=0.04
  3. no differences in 1° or 2° outcomes between aspirin strata


In the clonidine arm, Deveraux compared low-dose clonidine (200 μg per day, commenced just before surgery and until 72 hours post surgery) with placebo, and found:

  1. no difference in
    • the primary endpoint, a composite of death or nonfatal myocardial infarction at 30 days
      • clonidine: n=367 vs placebo: n=339
      • hazard ratio with clonidine 1.08, 95% CI 0.93 to 1.26; p=0.29
  2. clonidine was associated with increased incidence of
    • myocardial infarction
      • clonidine 6.6% vs placebo 5.9%
      • hazard ratio with clonidine 1.11, 95% CI 0.95 to 1.30; P=0.18
    • clinically important hypotension
      • 47.6% vs 37.1%

  1. significant inter-group differences with respect to the monitoring of central venous pressure and oxygen and the use of intravenous fluids, vasopressors, inotropes, and blood transfusions.
  2. 60 day mortality rates:
    • protocol-based EGDT group: 21.0%
    • protocol-based standard-therapy group 18.2%
    • usual-care group 18.9%
      • relative risk with protocol-based therapy vs. usual care, 1.04; 95% CI 0.82 to 1.31; P=0.83
      • relative risk with protocol-based EGDT vs. protocol-based standard therapy, 1.15; 95% CI 0.88 to 1.51; P=0.31
  3. There were no significant differences in
    • 90-day mortality
    • 1-year mortality
    • need for organ support

New England Journal of Medicine:     Septic Shock

Asfar and colleagues completed a multicenter, randomized, open-label trial in 776 patients with septic shock comparing resuscitation with a mean arterial pressure target of 80 to 85 mm Hg (high target group) with 65 to 70 mmHg (low target group), and found:

  1. no significant difference in
    • 28 day mortality
      • high target group 36.6% versus low target group 34.0%
        • hazard ratio in the high target group 1.07, 95% CI 0.84 to 1.38; p=0.57
    • 90 day mortality
      • high target group 43.8% versus low target group 42.3%
        • hazard ratio in the high-target group 1.04, 95% CI 0.83 to 1.30; p=0.74
    • serious adverse events
      • high target group 19.1% versus low target group 17.8%; p=0.64
    • an increased incidence of atrial fibrillation with high-target therapy

New England Journal of Medicine:     Severe Sepsis

Caironi and colleagues completed a multicenter, randomized, controlled, open-label trial in 1,818 patients with severe sepsis, comparing 20% albumin and crystalloid solution (targeting a serum albumin level of 30 g/L), with crystalloid solution alone, and found:

  1. no difference in
    • 28 day mortality (primary outcome)
      • albumin group 31.8% versus crystalloid group 32.0%
        • relative risk in the albumin group, 1.00; 95% CI 0.87 to 1.14; P=0.94
    • 90 day mortality
      • albumin group 41.1% versus crystalloid group 43.6%
        • relative risk 0.94; 95% CI 0.85 to 1.05; P=0.29
  2. no significant differences in other secondary outcomes
    • organ dysfunction:
      • number of patients
      • degree of dysfunction
    • length of stay
      • ICU 
      • hospital
  3. during the first 7 days, albumin therapy was associated with
    • higher mean arterial pressure (P=0.03)
    • lower net fluid balance (P<0.001)
  4. no significant difference in total daily administered fluid  (P=0.10)

Journal of the American Medical Association:     Severe Sepsis

Kaukonen et al performed a retrospective, observational study from 2000 to 2012, in 101,064 patients with severe sepsis in Australia and New Zealand, and found:

  1. a decrease in absolute mortality:
    • from 35.0% in 2000 (95% CI  33.2% to 36.8%) to 18.4% in 2012
