Procalcitonin as a marker of sepsis and outcome in patients with neurotrauma

Procalcitonin as a marker of sepsis and outcome in patients with neurotrauma: An observation study. BMC Anesthesiology, Dec 2013, 13:48.

Deng, S., et al.

http://www.biomedcentral.com/content/pdf/1471-2253-13-48.pdf

Procalcitonin (PCT) is a reliable biomarker of sepsis and infection. The level of PCT 
associated with sepsis and infection in patients with traumatic brain injury is currently 
unknown. The purpose of this study was to investigate the value of PCT and C-reactive 
protein (CRP) as diagnostic markers of sepsis and to evaluate the prognostic value of these 
markers related to the severity of injury, sepsis and mortality

A survey of the attitudes and perceptions of multidisciplinary team members towards family presence at bedside rounds in the intensive care unit

A survey of the attitudes and perceptions of multidisciplinary team members towards family presence at bedside rounds in the intensive care unit. Intensive and critical care nursing, Feb 2014, Vol. 30(1), p.13-21.

Santiago, C., et al.

http://www.intensivecriticalcarenursing.com/article/S0964-3397(13)00067-0/abstract?rss=yes

Objective: To describe the attitudes and perceptions of intensive care unit (ICU) staff [critical care physicians and fellows (MDs), registered nurses (RNs), allied health discipline (HD) and managers] towards family presence at bedside rounds. We developed, tested and administered a questionnaire to the multidisciplinary staff.

Prediction of death in less than 60 minutes following withdrawal of cardiorespiratory support in ICUs

Prediction of death in less than 60 minutes following withdrawal of cardiorespiratory support in ICUs. Critical care medicine, Dec 2013, Vol. 41(12), p.2677-87.

Brieva, J., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/12000/Prediction_of_Death_in_Less_Than_60_Minutes.2.aspx

Half of all ICU patients die within 60 minutes of withdrawal of cardiorespiratory support. Prediction of which patients die before and after 60 minutes would allow changes in service organization to improve patient palliation, family grieving, and allocation of ICU beds. This study tested various predictors of death within 60 minutes and explored which clinical variables ICU specialists used to make their prediction.


Understanding changes in established practice: Pulmonary artery catheter use in critically ill patients

Understanding changes in established practice: Pulmonary artery catheter use in critically ill patients. Critical care medicine, Dec 2013, Vol. 41(12), p.2667-76.

Gershengorn, H.B., and Wunsch, H.

http://journals.lww.com/ccmjournal/Abstract/2013/12000/Understanding_Changes_in_Established_Practice__.1.aspx

Multiple studies suggest that routine use of pulmonary artery catheters is not beneficial in critically ill patients. Little is known about the patterns of “uptake” of practice change that involves removal of a device previously considered standard of care, rather than adoption of a new technique or technology. Our objective was to assess recent pulmonary artery catheter use across ICUs and identify factors associated with high use.

ICU-acquired swallowing disorders

ICU-acquired swallowing disorders. Critical care medicine, Oct 2013, Vol. 41(10), p.2396-2405.

Macht, M., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/10000/ICU_Acquired_Swallowing_Disorders.16.aspx

Patients hospitalized in the ICU can frequently develop swallowing disorders, resulting in an inability to effectively transfer food, liquids, and pills from their mouth to stomach. The complications of these disorders can be devastating, including aspiration, reintubation, pneumonia, and a prolonged hospital length of stay. As a result, critical care practitioners should understand the optimal diagnostic strategies, proposed mechanisms, and downstream complications of these ICU-acquired swallowing disorders.

Body temperature patterns as a predictor of hospital-acquired sepsis in afebrile adult intensive care unit patients

Body temperature patterns as a predictor of hospital-acquired sepsis in afebrile adult intensive care unit patients: A case-control study. Critical care, Sept 2013, 17: R200

Drewry, A.M., et al.

http://ccforum.com/content/17/5/R200/abstract

Early treatment of sepsis improves survival, but early diagnosis of hospital-acquired sepsis, especially in critically ill patients, is challenging. Evidence suggests that subtle changes in body temperature patterns may be an early indicator of sepsis, but data is limited. The aim of this study was to examine whether abnormal body temperature patterns, as identified by visual examination, could predict the subsequent diagnosis of sepsis in afebrile critically ill patients. 



Resuscitation fluids

Resuscitation fluids. NEJM, Oct 2013, 369: 1243-51

Myburgh, J.A. and  Mythen, M.G.

http://www.cwrumedicine.org/images/current_residents/resuscitation%20fluids.pdf

Fluid resuscitation with colloid and crystalloid solutions is a ubiquitous intervention in acute medicine. The selection and use of resuscitation fluids is based on physiological principles, but clinical practice is determined largely by clinician preference with marked regional variation. No ideal resuscitation fluid exists. There is emerging evidence that the type and dose of resuscitation fluid may affect patient-centered outcomes.

Long-term cognitive impairment after critical illness

Long-term cognitive impairment after critical illness. NEJM, Oct 2013, 369: 1306-16

Pandharipande, P.P., et al.

http://www.nejm.org/doi/full/10.1056/NEJMoa1301372?af=R&rss=currentIssue

Survivors of critical illness often have a prolonged and disabling form of cognitive impairment that remains inadequately characterized. We enrolled adults with respiratory failure or shock in the medical or surgical intensive care unit (ICU), evaluated them for in-hospital delirium, and assessed global cognition and executive function 3 and 12 months after discharge.

Intensivists at night

Intensivists at night: putting resources in the right place. Critical care, October 2013, 17: 1008

Levy, M.M.

[no online link available]

During the past 50 years, caring for the critically ill has become increasingly complex and the need for an intensivist has become more evident. Management by intensivists has become a quality indicator for many ICUs. Numerous small studies have demonstrated the beneficial effect of intensivists on outcomes in the critically ill, and some clinicians have advanced the argument that a night-time intensivist is essential for the care of critically ill patients. In response, many institutions have hired full-time intensivists for both day and night coverage in the ICU. Two recent studies have been conducted that make a compelling argument for redirecting funding of night-time intensivists to areas of greater need in health care. In a retrospective analysis of a large database that involved more than 65,000 patients, no benefit of night-time intensivists could be found in ICUs where care is managed by intensivists during the day. Only in ICUs where management by intensivists is not mandated could a beneficial impact on mortality be found. The second study, a randomized controlled trial, evaluated the effect of night-time intensivists on length of stay, mortality, and other outcomes and was a negative trial. In this methodologically rigorous trial, there was no difference in outcomes between the intensivist and control group, which consisted of in-house resident coverage at night with availability by telephone of fellows and intensivists. These two robust studies clearly suggest that night-time intensivists do not improve mortality in ICUs managed by intensivists during the day. Though possibly beneficial in low-intensity environments, the widespread drive to add night-time intensivist coverage may have been premature.

Schandl, A., et al.

http://ccforum.com/content/pdf/cc13018.pdf

Guidelines recommend follow-up for patients after intensive care unit (ICU) stay. Methods for identifying patients with psychological problems after intensive care would be of value, to optimize treatment and to improve adequate resource allocation in ICU followup of ICU survivors. The aim of the study was to develop a predictive screening instrument – for use at ICU discharge – to identify patients at risk for post-traumatic stress, anxiety or depression.

A prospective longitudinal multicentre study of health related qualify of life in ICU survivors with COPD

A prospective longitudinal multicentre study of health related quality of life of ICU survivors with COPD. Critical care, Sept 2013, 17:R211

Berkius, J., et al.

http://ccforum.com/content/pdf/cc13019.pdf

Mortality amongst COPD patients treated on the ICU is high. Health-related quality of life (HRQL) after intensive care is a relevant concern for COPD patients, their families and providers of health care. Still, there are few HRQL studies after intensive care of this patient group. Our hypothesis was that HRQL of COPD patients treated on the ICU declines rapidly with time.

Severe sepsis and septic shock

Severe sepsis and septic shock.  N Engl J Med 2013; 369: p.840-851

Angus, D.C. and van der Poll, T.

http://www.nejm.org/doi/full/10.1056/NEJMra1208623?af=R&rss=currentIssue

Sepsis is one of the oldest and most elusive syndromes in medicine. Hippocrates claimed that sepsis (σήψις) was the process by which flesh rots, swamps generate foul airs, and wounds fester.Galen later considered sepsis a laudable event, necessary for wound healing. With the confirmation of germ theory by Semmelweis, Pasteur, and others, sepsis was recast as a systemic infection, often described as “blood poisoning,” and assumed to be the result of the host's invasion by pathogenic organisms that then spread in the bloodstream. However, with the advent of modern antibiotics, germ theory did not fully explain the pathogenesis of sepsis: many patients with sepsis died despite successful eradication of the inciting pathogen.

Leone, M., et al.

http://ccforum.com/content/17/4/R170/abstract

In patients with ventilator-associated pneumonia (VAP), administration of an appropriate empirical antimicrobial treatment is associated with improved outcomes, leading to the prescription of broad-spectrum antibiotics including drugs active against methicillin resistant Staphylococcus aureus (MRSA). In order to avoid the overuse of antibiotics, the present study aimed to evaluate the technical characteristics of a rapid diagnostic test (Cepheid Xpert assay) in patients with suspected VAP.

Screening and risk factors of exocrine pancreatic insufficiency in critically ill adult patients

Screening and risk factors of exocrine pancreatic insufficiency in critically ill adult patients receiving enteral nutrition. Critical care, Aug 2013, 17 R171.

Wang, S., et al.

http://ccforum.com/content/17/4/R171/abstract

Malnutrition is a frequent problem associated with detrimental clinical outcomes in critically ill patients. To avoid malnutrition, most studies focus on the prevention of inadequate nutrition delivery, whereas little attention is paid to the potential role of exocrine pancreatic insufficiency (EPI). We therefore aim to evaluate the prevalence of EPI and identify its potential risk factors in critically ill adult patients without pre-existing pancreatic diseases.

The August 29 issue of the NEJM will include the first in a series of review articles on critical care. Critical care is a young specialty that is generally considered to have developed from the successful use of invasive ventilation during the 1952 polio epidemic in Copenhagen. From these beginnings, critical care has spread to most countries in the world. In many developed societies, the number of critical care beds is increasing while total number of acute care hospital beds is decreasing; the proportion of acute care hospital beds that are intensive care unit beds is increasing substantially.

Surviving intensive care

Surviving intensive care: A systematic review of healthcare resource use after hospital discharge. Critical care medicine, Aug 2013, Vol. 41(8), p.1832-43.

Lone, N.I., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/Surviving_Intensive_Care___A_Systematic_Review_of.2.aspx

Intensive care survivors continue to experience significant morbidity following acute hospital discharge, but healthcare costs associated with this ongoing morbidity are poorly described. As the demand for intensive care increases, understanding the magnitude of postacute hospital healthcare costs is of increasing relevance to clinicians and healthcare planners. We undertook a systematic review of the literature reporting major healthcare resource use by intensive care survivors following discharge from the hospital and identified factors associated with increased resource use.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/Atypical_Sleep_in_Ventilated_Patients___Empirical.16.aspx

Standard sleep scoring criteria may be unreliable when applied to critically ill patients. We sought to quantify typical and atypical polysomnographic findings in critically ill patients and to begin development and reliability testing of methodology to characterize the atypical polysomnographic tracings that confound standard sleep scoring criteria.

Clostridium difficile infection

Clostridium difficile infection: A multicenter study of epidemiology and outcomes in mechanically ventilated patients. Critical care medicine, Aug 2013, Vol. 41(8), p.1968-75.

Micek, S.T., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/Clostridium_difficile_Infection___A_Multicenter.17.aspx

Clostridium difficile is a leading cause of hospital-associated infection in the United States. The purpose of this study is to assess the prevalence of C. difficile infection among mechanically ventilated patients within the ICUs of three academic hospitals and secondarily describe the influence of C. difficile infection on the outcomes of these patients.

Berg, A., et al.

http://ccforum.com/content/17/4/R158/abstract

Optimal feeding of critically ill patients in the ICU is controversial. Existing guidelines rest on rather weak evidence. Whole body protein kinetics may be an attractive technique for assessing optimal protein intake. In this study, critically ill patients were investigated during hypocaloric and normocaloric IV nutrition.

A systematic review of evidence-informed practices for patient care rounds in the ICU

A systematic review of evidence-informed practices for patient care rounds in the ICU. Critical care medicine, Vol. 41(8), p.2015-29.

Lane, D., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/A_Systematic_Review_of_Evidence_Informed_Practices.23.aspx

Patient care rounds are a key mechanism by which healthcare providers communicate and make patient care decisions in the ICU but no synthesis of best practices for rounds currently exists. Therefore, we systematically reviewed the evidence for facilitators and barriers to patient care rounds in the ICU.

Body mass index is associated with hospital mortality in critically ill patients

Body mass index is associated with hospital mortality in critically ill patients: An observational cohort study. Critical care medicine, August 2013, Vol. 41(8), p.1878-83.

Pickkers, P., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/Body_Mass_Index_Is_Associated_With_Hospital.7.aspx

Obesity is associated with a variety of diseases, which results in a decreased overall life expectancy. Nevertheless, some studies suggest that being overweight may reduce hospital mortality of certain patient groups, referred to as obesity paradox. Conflicting results for critically ill patients are reported. Therefore, we wished to investigate the association of body mass index and hospital mortality in critically ill patients.

Surviving intensive care

Surviving intensive care: A systematic review of healthcare resource use after hospital discharge. Critical care medicine, August 2013, Vol. 41(8), p.1832-43.

Lone, N.I., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/Surviving_Intensive_Care___A_Systematic_Review_of.2.aspx

Intensive care survivors continue to experience significant morbidity following acute hospital discharge, but healthcare costs associated with this ongoing morbidity are poorly described. As the demand for intensive care increases, understanding the magnitude of post-acute hospital healthcare costs is of increasing relevance to clinicians and healthcare planners. We undertook a systematic review of the literature reporting major healthcare resource use by intensive care survivors following discharge from the hospital and identified factors associated with increased resource use.

Fever in adult ICUs

Fever in adult ICUs: An interrupted time series analysis. Critical care medicine, August 2013, Vol. 41(8), p.1863-69.

Niven, D.J., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/08000/Fever_in_Adult_ICUs___An_Interrupted_Time_Series.5.aspx

Fever is common and associated with increased mortality among patients admitted to adult ICUs, yet recent literature suggests that the incidence of fever may be decreasing. The objective of this study was to determine whether the incidence of fever in adult ICUs changed over time and the factors responsible for the observed change.

Therapeutic hypothermia: is it effective for non-VF/VT cardiac arrest?

Therapeutic hypothermia: is it effective for non-VF/VT cardiac arrest? Critical care, March 2013, 17: 215

Sandroni, C., et al.

http://ccforum.com/content/pdf/cc12524.pdf

Sudden cardiac death represents a major health problem. In adults, the prevalence of out-of-hospital cardiac arrest (OHCA) attended by the emergency medical services (EMS) ranges from 52 to 112 per 100,000 person-years in developed countries, whereas the prevalence of adult in-hospital cardiac arrest (IHCA) ranges from 1 to 5 per 1,000 patient admissions. Mortality from cardiac arrest exceeds 90 % in OHCA 
and 70 % in most studies on IHCA. Patients who have a shock able rhythm, i.e., ventricular fibrillation 
(VF) or pulseless ventricular tachycardia (VT), on initial electrocardiogram (EKG) have a consistently higher 
survival than those whose initial cardiac rhythm is nonshockable, i.e., asystole or pulseless electrical activity 
(PEA).

Monnet, X. and Teboul, J-L.

http://ccforum.com/content/pdf/cc12526.pdf

Predicting which patients with acute circulatory failure will respond to fluid by a significant increase in cardiac output is a daily challenge, in particular in the setting of the intensive care unit (ICU). This challenge has become even more crucial because evidence is growing that administering excessive amounts of fluid is a risk factor in critically ill patients, in particular in patients with lung injury.

Patient monitoring alarms in the ICU and in the operating room

Patient monitoring alarms in the ICU and in the operating room. Critical care, March 2013, 17: R216

Schmid, F., et al.

http://ccforum.com/content/pdf/cc12525.pdf

In complex fields of work like aviation, mining, anesthesiology, and intensive care medicine – and here
particularly with regard to monitoring of vital functions – alarms are ubiquitous and have been the subject of
medical, technical, and psychological research for decades. Monitoring of vital functions and function
of life-support devices is essential for critically ill patients, although real evidence based data are missing.

An exploration of social and economic outcome and associated health-related quality of life after critical illness in general intensive care unit survivors

An exploration of social and economic outcome and associated health-related quality of life after critical illness in general intensive care unit survivors: A 12-month follow-up study. Critical care, May 2013, R:100

Griffiths, J., et al.

http://ccforum.com/content/pdf/cc12745.pdf

The socio-economic impact of critical illnesses on patients and their families in Europe has yet to be
determined. The aim of this exploratory study was to estimate changes in family circumstances, social and
economic stability, care requirements and access to health services for patients during their first 12 months after ICU discharge.

Cardiac ischemia in patients with septic shock randomized to vasopressin or narepinephrine

Cardiac ischemia in patients with septic shock randomized to vasopressin or norepinephrine. Critical care, June 2013, 17:R117

Mehta, S., et al.

http://ccforum.com/content/pdf/cc12789.pdf

Cardiac ischemia occurs frequently in critically ill patients, and is associated with increased mortality. Given that most critically ill patients cannot communicate symptoms, the diagnosis of cardiac ischemia can be challenging and necessitates that clinicians rely on cardiac biomarkers and electrocardiograms (ECGs). Patients receiving vasopressors may be at even higher risk of cardiac ischemia than other patients because of coronary artery vasoconstriction, increased systemic vasoconstriction-induced afterload, or catecholamine-driven increases in myocardial oxygen demand. 

Continuous on-line glucose measurement by microdialysis in a central vein

Continuous on-line glucose measurement by microdialysis in a central vein. A pilot study. Critical care, May 2013, 17:R87

Blixt, C., et al.

http://ccforum.com/content/17/3/R87

Tight glucose control in the ICU has been proven difficult with an increased risk for hypoglycaemic episodes. Also the variability of glucose may have an impact on morbidity. An accurate and feasible on-line/continuous measurement is therefore desired. In this study a central vein catheter with a microdialysis membrane in combination with an on-line analyzer for continuous monitoring of circulating glucose and lactate by the central route was tested.

Turon, M., et al.

http://ccforum.com/content/pdf/cc12719.pdf

Advances in ICUs have raised survival rates, but they have highlighted the need to reduce the morbidity of ICU patients and improve their short- and long-term functional outcomes. Frequently these patients, especially with acute respiratory distress syndrome, present neurocognitive impairments that extend beyond their acute phase and hospital stay and lead to significant deficits in quality of life.

Blanch, L., et al.

http://ccforum.com/content/pdf/cc12769.pdf

Clinical work and continuous investigation have improved the outcome of critically ill patients over time. Nowadays, innovation pulled by demand and translational research projects of excellence will constitute new opportunities for clinicians to improve care and provide economic incentives to be returned to the patient, institutions, and society.

Early alterations of B cells in patients with septic shock: another piece in the complex puzzle of the immune response in sepsis

Early alterations of B cells in patients with septic shock: another piece in the complex puzzle of the immune response to sepsis. Critical care, 2013, 17: 162

Girardis, M. and Cossarizza, A.

[No link available]

Impairment of the inflammatory-immune response is currently accepted as a hallmark of severe sepsis even in the early stages of the disease. In this context, the alterations of the circulating B-lymphocytes have never been described in detail. The study by Monserrat and colleagues in the previous issue of Critical Care indicated that, in patients with septic shock, the B-cell compartment is early and deeply altered with different patterns in subset distribution and activation between survivors and non-survivors.

The obesity paradox in the ICU

The obesity paradox in the ICU: real or not? Critical care, June 2013, 17: 154.

Dickerson, R.N.

[no link available]

The obesity paradox has been used to describe the observed phenomenon described by several studies that indicated improved survival for critically ill patients with mild to moderate obesity when compared with their lean counterparts. The study by Arabi and coworkers challenges the obesity paradox concept for critically ill obese patients with septic shock. Their data indicate that obesity, per se, does not significantly improve mortality when outcomes are adjusted for differences in baseline characteristics and sepsis interventions. Further studies are needed to assess the influence of body weight, lean weight, and fat mass for optimizing fluid resuscitation, pharmacotherapy, and nutritional therapy for critically ill patients with sepsis.

Intensive care sedation

Intensive care sedation: the past, present and the future. Critical care, June 2013, 17: 332.

Shehabi, Y., et al.

[no link available]

Despite the universal prescription of sedative drugs in the intensive care unit (ICU), current practice is not guided by high-level evidence. Landmark sedation trials have made significant contributions to our understanding of the problems associated with ICU sedation and have promoted changes to current practice. We identified challenges and limitations of clinical trials which reduced the generalizability and the universal adoption of key interventions. We present an international perspective regarding current sedation practice and a blueprint for future research, which seeks to avoid known limitations and generate much-needed high-level evidence to better guide clinicians' management and therapeutic choices of sedative agents.

Hospital variation and temporal trends in palliative and end-of-life care in the ICU

Hospital variation and temporal trends in palliative and end-of-life care in the ICU. Critical care medicine, June 2013, Vol. 41(6), p.1404-11

DeCato, T.W., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/06000/Hospital_Variation_and_Temporal_Trends_in.3.aspx

Although studies have shown regional and interhospital variability in the intensity of end-of-life care, few data are available assessing variability in specific aspects of palliative care in the ICU across hospitals or interhospital variability in family and nurse ratings of this care. Recently, relatively high family satisfaction with ICU end-of-life care has prompted speculation that ICU palliative care has improved over time, but temporal trends have not been documented.

Uy, J., et al.

http://journals.lww.com/ccmjournal/Abstract/2013/06000/Physicians__Decision_Making_Roles_for_an_Acutely.15.aspx

There is substantial variation in use of life sustaining technologies in patients near the end of life but little is known about variation in physicians’ initial ICU admission and intubation decision making processes. Our objective is to describe variation in hospital-based physicians’ communication behaviors and decision-making roles for ICU admission and intubation decisions for an acutely unstable critically and terminally ill patient.

Steele, T., et al.

http://ccforum.com/content/17/3/R106/abstract

Hypocalcemia is common in critically ill patients. However, its clinical course during the early days of admission and the role of calcium supplementation remain uncertain, and the assessment of calcium status is inconsistent. We aimed to establish the course of hypocalcemia during the early days of critical illness in relation to mortality and to assess the impact of calcium supplementation on calcium normalization and mortality.

Systematic reviews suggest adult patients in intensive care units (ICUs) with relative contraindications to early enteral nutrition (EN) may benefit from parenteral nutrition (PN) provided within 24 hours of ICU admission. Objective:  To determine whether providing early PN to critically ill adults with relative contraindications to early EN alters outcomes.

Continuous electroencephalography monitoring in critically ill patients

Continuous electroencephalography monitoring in critically ill patients: indications, limitations and strategies. Critical care medicine, April 2013, Vol. 41(4), p.1124-32

Sutter, R., et al.

[Link not available]

OBJECTIVE: Continuous electroencephalography as a bedside monitor of cerebral activity has been used in a range of critically ill patients. This review compiles the indications, limitations, and strategies for continuous electroencephalography in the ICU. DATA SOURCE: The authors searched the electronic MEDLINE database.
STUDY SELECTION AND DATA EXTRACTION: References from articles of special interest were selected.
DATA SYNTHESIS AND CONCLUSION: Electroencephalographically-defined suppression is routinely used as the basis for titration of pharmacologic therapy in refractory status epilepticus and intracranial hypertension. The increasing use of continuous electroencephalography reveals a clinically underappreciated burden of epileptiform and epileptic activity in patients with primary acute neurologic disorders, and also in critically ill patients with acquired encephalopathy. Status epilepticus is reported with continuous electroencephalography in 1% to 10% of patients with ischemic stroke, 8% to 14% with traumatic brain injury, 10% to 14% with subarachnoid hemorrhage, 1% to 21% with intracerebral hemorrhage, and 30% of patients following cardiorespiratory arrest. These figures underscore the importance of continuous electroencephalography in the critically ill. The interpretation of continuous electroencephalography in the ICU is challenged by electroencephalography artifacts and the frequent subtle differences between ictal and interictal patterns.

Sex and severe sepsis

Sex and severe sepsis. Critical care 2013, 17:144

Guidet, B. and Maury, E.

http://ccforum.com/content/17/3/144

Epidemiological studies document that males are more prone than females to develop severe sepsis and this is confirmed by Sakr and colleagues in the previous issue of Critical Care. However, the impact of gender on prognosis of severe sepsis is a matter of debate. Sakr and colleagues report a higher mortality in septic females than in males. This puzzling result might be explained by confounding factors such as age, nosocomial infections, follow-up period, and case mix. The impact of sexual hormones in older females is less relevant. Treatments aimed at modifying sexual hormone profile are promising but need to be tested in future trials.

The importance of adequate sleep for good health and immune system function is well documented as is reduced sleep quality experienced by ICU patients. In this issue of Critical Care, Elliot and co-workers present, a well done, largest of its kind, single center study on sleep patterns in critically ill patients. They base their study on the "gold standard", the polysomnography technique (PSG), which is resource demanding to perform and often difficult to evaluate.

http://www.ncbi.nlm.nih.gov/pubmed/23263574?dopt=Abstract

The management of hypoxemia in critically ill patients is challenging. Whilst the harms of tissue hypoxia are well recognized, the possibility of harm from excess oxygen administration, or other interventions targeted at mitigating hypoxemia, may be inadequately appreciated. The benefits of attempting to fully reverse arterial hypoxemia may be outweighed by the harms associated with high concentrations of supplemental oxygen and invasive mechanical ventilation strategies. We propose two novel related strategies for the management of hypoxemia in critically ill patients.

Maintaining effective plasma volume is, perhaps, the most persistent challenge faced by clinicians who treat critically ill patients, in particular those with sepsis. In patients with sepsis, increased capillary permeability and loss of vascular tone cause loss of circulating plasma volume, which contributes to inadequate cardiac output and tissue perfusion.
