2017 Dec - Are high nurse workload/staffing ratios associated with decreased survival in critically ill patients? A cohort study

Lee A, Cheung YSL, Joynt GM, Leung CCH, Wong WT, Gomersall CD.; Ann Intensive Care. 2017 Dec;7(1):46. doi: 10.1186/s13613-017-0269-2. Epub 2017 May 2.

BACKGROUND: Despite the central role of nurses in intensive care, a relationship between intensive care nurse workload/staffing ratios and survival has not been clearly established. We determined whether there is a threshold workload/staffing ratio above which the probability of hospital survival is reduced and then modeled the relationship between exposure to inadequate staffing at any stage of a patient's ICU stay and risk-adjusted hospital survival.

2017 Apr - Diagnostic accuracy of quantitative neuromuscular ultrasound for the diagnosis of intensive care unit-acquired weakness: a cross-sectional observational study

Witteveen E, Sommers J, Wieske L, Doorduin J, van Alfen N, Schultz MJ, van Schaik IN, Horn J, Verhamme C.; Ann Intensive Care. 2017 Dec;7(1):40. doi: 10.1186/s13613-017-0263-8. Epub 2017 Apr 5.

BACKGROUND: Neuromuscular ultrasound is a noninvasive investigation, which can be easily performed at the bedside on the ICU. A reduction in muscle thickness and increase in echo intensity over time have been described in ICU patients, but the relation to ICU-acquired weakness (ICU-AW) is unknown. We hypothesized that quantitative assessment of muscle and nerve parameters with ultrasound can differentiate between patients with and without ICU-AW. The aim of this cross-sectional study was to investigate the diagnostic accuracy of neuromuscular ultrasound for diagnosing ICU-AW.

2016 Dec - Outcomes and survival prediction models for severe adult acute respiratory distress syndrome treated with extracorporeal membrane oxygenation

Rozencwajg S, Pilcher D, Combes A, Schmidt M.; Crit Care. 2016 Dec 5;20(1):392. Review.

Extracorporeal membrane oxygenation (ECMO) for severe acute respiratory distress syndrome (ARDS) has known a growing interest over the last decades with promising results during the 2009 A(H1N1) influenza epidemic. Targeting populations that can most benefit from this therapy is now of major importance.Survival has steadily improved for a decade, reaching up to 65% at hospital discharge in the most recent cohorts. However, ECMO is still marred by frequent and significant complications such as bleeding and nosocomial infections. In addition, physiological and psychological symptoms are commonly described in long-term follow-up of ECMO-treated ARDS survivors. Because this therapy is costly and exposes patients to significant complications, seven prediction models have been developed recently to help clinicians identify patients most likely to survive once ECMO has been initiated and to facilitate appropriate comparison of risk-adjusted outcomes between centres and over time. Higher age, immunocompromised status, associated extra-pulmonary organ dysfunction, low respiratory compliance and non-influenzae diagnosis seem to be the main determinants of poorer outcome.

2017 Jan - Whole-body vibration to prevent intensive care unit-acquired weakness: safety, feasibility, and metabolic response

Wollersheim T, Haas K, Wolf S, Mai K, Spies C, Steinhagen-Thiessen E, Wernecke KD, Spranger J, Weber-Carstens S.: Crit Care. 2017 Jan 9;21(1):9.

Background:Intensive care unit (ICU)-acquired weakness in critically ill patients is a common and significant complication affecting the course of critical illness. Whole-body vibration is known to be effective muscle training and may be an option in diminishing weakness and muscle wasting. Especially, patients who are immobilized and not available for active physiotherapy may benefit. Until now whole-body vibration was not investigated in mechanically ventilated ICU patients. We investigated the safety, feasibility, and metabolic response of whole-body vibration in critically ill patients.

2016 Dec - Passive leg raise testing effectively reduces fluid administration in septic shock after correction of non-compliance to test results

Rameau A, de With E, Boerma EC.; Ann Intensive Care. 2017 Dec;7(1):2.

Background: Fluid resuscitation is considered a cornerstone of shock treatment, but recent data have underlined the potential hazards of fluid overload. The passive leg raise (PLR) test has been introduced as one of many strategies to predict ‘fluid responsiveness.’ The use of PLR testing is applicable to a wide range of clinical situations and has the potential to reduce fluid administration, since PLR testing is based upon (reversible) autotransfusion. Despite these theoretical advantages, data on the net effect on fluid balance as a result of PLR testing remain scarce.

2016 Dec - Extracorporeal membrane oxygenation for pheochromocytoma-induced cardiogenic shock

Hekimian G, Kharcha F, Bréchot N, Schmidt M, Ghander C, Lebreton G, Girerd X, Tresallet C, Trouillet JL, Leprince P, Chastre J, Combes A, Luyt CE.; Ann Intensive Care. 2016 Dec;6(1):117.

Background: Pheochromocytoma, a rare catecholamine-producing tumor, might provoke stress-induced Takotsubo-like cardiomyopathy and severe cardiogenic shock. Because venoarterial-extracorporeal membrane oxygenation (VA-ECMO) rescue of pheochromocytoma-induced refractory cardiogenic shock has rarely been reported, we reviewed our ICU patients’ presentations and outcomes.

2016 Dec - Antibiotic Dosing in Patients With Acute Kidney Injury: : "Enough But Not Too Much"

Lewis SJ, Mueller BA.; J Intensive Care Med. 2016 Mar;31(3):164-76.

Increasing evidence suggests that antibiotic dosing in critically ill patients with acute kidney injury (AKI) often does not achieve pharmacodynamic goals, and the continued high mortality rate due to infectious causes appears to confirm these findings. Although there are compelling reasons why clinicians should use more aggressive antibiotic dosing, particularly in patients receiving aggressive renal replacement therapies, concerns for toxicity associated with higher doses are real. The presence of multisystem organ failure and polypharmacy predispose these patients to drug toxicity. This article examines the pharmacokinetic and pharmacodynamic consequences of critical illness, AKI, and renal replacement therapy and describes potential solutions to help clinicians give “enough but not too much” in these very complicated patients.
