Whether selective decontamination of the digestive tract (SDD) reduces mortality among patients undergoing mechanical ventilation and whether it adversely affects microbial ecology in the intensive care unit (ICU) remain unclear. In an earlier analysis of data from Australia, SDD did not result in a lower incidence of in-hospital death than standard care, but data from the full international trial are needed. We randomly assigned ICUs in Australia and Canada to use SDD or to continue standard care for two 12-month periods in patients undergoing mechanical ventilation. Patients in the SDD group received specific oral and gastric antimicrobial interventions for the duration of ventilation and an intravenous antibiotic agent for the first 4 days after enrollment. All other patients in the ICU were included in an observational ecologic assessment. Previously reported data from Australia are now combined with data from Canada. The primary outcome was in-hospital death from any cause at 90 days. The secondary clinical outcomes, assessed at 90 days, were death in the ICU and the number of days alive and free of mechanical ventilation, ICU admission, and hospitalization. Microbiologic secondary outcomes included new positive cultures for bloodstream infections and antibiotic-resistant organisms. For the ecologic assessment, the microbiologic outcomes were tested for noninferiority (noninferiority margin, 2 percentage points). In this trial involving 20,000 patients in 26 ICUs, 9289 patients were enrolled in the randomized trial and 10,711 were included in the ecologic assessment. At 90 days, 1175 of 4215 patients (27.9%) in the SDD group and 1494 of 5065 (29.5%) in the standard-care group had died before hospital discharge (odds ratio, 0.94; 95% confidence interval [CI], 0.84 to 1.05; P = 0.27). New bloodstream infections occurred in 4.9% of the patients in the SDD group and in 6.8% of those in the standard-care group (adjusted mean difference, -1.30 percentage points; 95% CI, -2.55 to -0.05); antibiotic-resistant organisms were cultured in 16.8% and 26.8%, respectively (adjusted mean difference, -9.60 percentage points; 95% CI, -12.40 to -6.80). In the ecologic assessment, noninferiority of SDD was not confirmed for the development of new antibiotic-resistant organisms. Adverse events considered to be related to SDD or standard care were reported in 12 patients (0.3%) in the SDD group and in no patients in the standard-care group. Serious adverse events occurred in 47 patients (1.1%) and 59 patients (1.2%), respectively. Among critically ill patients undergoing mechanical ventilation, SDD did not result in a lower incidence of in-hospital death than standard care.

Injuries are a major source of mortality and morbidity in China with approximately 66 million citizens requiring emergency medical care. Trauma registries provide the basis for quality assurance processes and inform the treatment of the injured patient. Against the backdrop of the recently established Chinese National Injury Surveillance System, the feasibility of establishing a multicentre trauma registry in a limited number of hospitals was examined. Seven hospital directors reported on a range of hospital characteristics including patient volume information and the types of patient information routinely collected. The findings indicate significant numbers of patients presenting due to injury, though little comparability in the type of information collected both between hospitals and with international trauma registry systems. The development of multicentre trauma registry is suggested as a way to monitor trauma system performance. The integration of clinical indicators into the National Injury Surveillance System in the long term is also recommended.

PurposeTo investigate the impact of hydrocortisone treatment and illness severity on health-related quality of life (HRQoL) at 6 months in septic shock survivors from the ADRENAL trial.MethodsUsing the EuroQol questionnaire (EQ-5D-5L) at 6 months after randomization we assessed HRQoL in patient subgroups defined by hydrocortisone or placebo treatment, gender, illness severity (APACHE II < or ≥ 25), and severity of shock (baseline peak catecholamine doses < or ≥ 15 mcg/min). Additionally, in subgroups defined by post-randomisation variables; time to shock reversal (days), treatment with renal replacement therapy (RRT), and presence of bacteremia.ResultsAt 6 months, there were 2521 survivors. Of these 2151 patients (85.3%-1080 hydrocortisone and 1071 placebo) completed 6-month follow-up. Overall, at 6 months the mean EQ-5D-5L visual analogue scale (VAS) was 70.8, mean utility score 59.4. Between 15% and 30% of patients reported moderate to severe problems in any given HRQoL domain. There were no differences in any EQ-5D-5L domain in patients who received hydrocortisone vs. placebo, nor in the mean VAS (p = 0.6161), or mean utility score (p = 0.7611). In all patients combined, males experienced lower pain levels compared to females [p = 0.0002). Neither higher severity of illness or shock impacted reported HRQoL. In post-randomisation subgroups, longer time to shock reversal was associated with increased problems with mobility (p = < 0.0001]; self-care (p = 0.0.0142), usual activities (p = <0.0001] and pain (p = 0.0384). Amongst those treated with RRT, more patients reported increased problems with mobility (p = 0.0307) and usual activities (p = 0.0048) compared to those not treated. Bacteraemia was not associated with worse HRQoL in any domains of the EQ-5D-5L.ConclusionsApproximately one fifth of septic shock survivors report moderate to extreme problems in HRQoL domains at 6 months. Hydrocortisone treatment for septic shock was not associated with improved HRQoL at 6 months. Female gender was associated with worse pain at 6 months.

To report the occurrence of life-threatening hyperkalaemia following treatment with therapeutic thiopentone coma. The neurosurgical intensive care units of Royal North Shore Hospital and Liverpool Hospital, Sydney, Australia. Three patients treated with theraputic thiopentone coma. One patient with raised intracranial pressure secondary to a severe traumatic brain injury and two patients with refractory vasospasm secondary to subarachnoid haemorrhage. Two of the three patients developed hypokalaemia on starting thiopentone, which was resistant to potassium supplementation. All three patients developed severe hyperkalaemia during the recovery phase of coma. This was life-threatening in all three patients and fatal in one. Severe hypokalaemia refractory to potassium therapy may occur during therapeutic thiopentone coma. Severe rebound hyperkalaemia may occur after cessation of thiopentone infusion. Protocols for the management of patients with therapeutic barbiturate coma should recognise this potentially serious complication.

Cardiac index (l/min/m2) Pulmonary artery occlusion pressure (mm Hg) Left ventricular ejection fraction (%) Days in intensive care unit Normal range 2.5-3.6 6-15 55-75 - Case 1 3.9 21 20 13 Case 2 1.9 17 30 26 Case 3 3.1 30 35 22 Case 4 1.9 20 30 14 Case 5 2.3 36 20 41 Case 2-A 62 year old man was admitted to hospital after having collapsed. After admission to the intensive care unit echocardiography showed diffuse left ventricular dysfunction (ejection fraction 35%), and pulmonary artery catheter data confirmed cardiogenic shock (table 1 ). The combination of electrocardiographic changes and cardiogenic shock may be misdiagnosed as acute myocardial infarction, but echocardiography shows global myocardial injury rather than segmental injury in the distribution of a particular coronary artery.

The World Health Organization has adopted a resolution on improving the prevention, diagnosis, and management of sepsis. Millions of lives can be saved if politicians, policymakers, health care administrators, researchers, and clinicians take coordinated actions.

In a study of fluid resuscitation, patients received 6% hydroxyethyl starch (HES; 130/0.4) or saline until ICU discharge or death or for 90 days. There was no significant difference in 90-day mortality, although more patients in the HES group received renal-replacement therapy. The administration of intravenous fluids to increase intravascular volume is a frequent intervention in the intensive care unit (ICU), but the choice of resuscitation fluid remains controversial. 1 , 2 Globally, 0.9% sodium chloride (saline) is the most commonly used fluid, although colloids are administered as often as crystalloids, and hydroxyethyl starch (HES) is the most frequently used colloid. 3 Several studies have questioned the safety of HES in critically ill patients, with particular concern that its use increases the risk of acute kidney injury. 4 , 5 Most concern has focused on the use of concentrated HES solutions (10%) with a molecular weight of . . .

The efficacy of drotrecogin alpha (activated) (DrotAA) for sepsis has been controversial. In this trial, there was no significant difference in all-cause mortality at 28 or 90 days between adults with sepsis who were treated with DrotAA and those treated with placebo. Recombinant human activated protein C, or drotrecogin alfa (activated) (DrotAA), was approved for the treatment of severe sepsis in 2001 on the basis of the Prospective Recombinant Human Activated Protein C Worldwide Evaluation in Severe Sepsis (PROWESS) study, 1 a phase 3 international, randomized, controlled trial that was stopped early for efficacy after the enrollment of 1690 patients with severe sepsis. Absolute mortality in the intention-to-treat population was reduced by 6.1 percentage points, a relative risk reduction of 19.4%. Subsequent subgroup analysis suggested that the mortality benefit was limited to patients with increased illness severity (i.e., those with more than one . . .

Sepsis is life-threatening organ dysfunction due to a dysregulated host response to infection. It is considered a major cause of health loss, but data for the global burden of sepsis are limited. As a syndrome caused by underlying infection, sepsis is not part of standard Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) estimates. Accurate estimates are important to inform and monitor health policy interventions, allocation of resources, and clinical treatment initiatives. We estimated the global, regional, and national incidence of sepsis and mortality from this disorder using data from GBD 2017. We used multiple cause-of-death data from 109 million individual death records to calculate mortality related to sepsis among each of the 282 underlying causes of death in GBD 2017. The percentage of sepsis-related deaths by underlying GBD cause in each location worldwide was modelled using mixed-effects linear regression. Sepsis-related mortality for each age group, sex, location, GBD cause, and year (1990–2017) was estimated by applying modelled cause-specific fractions to GBD 2017 cause-of-death estimates. We used data for 8·7 million individual hospital records to calculate in-hospital sepsis-associated case-fatality, stratified by underlying GBD cause. In-hospital sepsis-associated case-fatality was modelled for each location using linear regression, and sepsis incidence was estimated by applying modelled case-fatality to sepsis-related mortality estimates. In 2017, an estimated 48·9 million (95% uncertainty interval [UI] 38·9–62·9) incident cases of sepsis were recorded worldwide and 11·0 million (10·1–12·0) sepsis-related deaths were reported, representing 19·7% (18·2–21·4) of all global deaths. Age-standardised sepsis incidence fell by 37·0% (95% UI 11·8–54·5) and mortality decreased by 52·8% (47·7–57·5) from 1990 to 2017. Sepsis incidence and mortality varied substantially across regions, with the highest burden in sub-Saharan Africa, Oceania, south Asia, east Asia, and southeast Asia. Despite declining age-standardised incidence and mortality, sepsis remains a major cause of health loss worldwide and has an especially high health-related burden in sub-Saharan Africa.
