Abstract
Necrotising soft tissue infections can affect the skin, subcutaneous tissue, superficial fascia, deep fascia and musculature. The infections are severe, they spread quickly and can result in extensive tissue loss. Although rare, morbidity and mortality rates are high. Early clinical identification is crucial for the outcome, and rapid infection control through surgery and targeted antibiotic treatment is needed to save lives. Few prospective clinical trials have been conducted for the treatment of this type of infection. Specific challenges include rapid identification of the condition and the uncertain efficacy of the various treatment options. In this clinical review article, we describe clinical characteristics, diagnostics and treatment.

Associations between enteral nutrition and outcomes in the SUP-ICU trial: Protocol for exploratory post hoc analyses. Acta Anaesthesiol Scand 2023; 67:481-486. [PMID: 36636785 DOI: 10.1111/aas.14194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 01/01/2023] [Indexed: 01/14/2023]
Abstract
Critically ill patients are at risk of gastrointestinal (GI) bleeding. Counter measures to minimise this risk include the use of pharmacological stress ulcer prophylaxis (SUP). The effect of enteral nutrition as SUP on GI bleeding event rates is unknown. There are conflicting data describing the effect of co-administration of enteral nutrition with pharmacological SUP, and there is substantial variation in practice. We aim to conduct an exploratory post hoc analysis to evaluate the association of enteral nutrition with clinically important GI bleed rates in ICU patients included in the SUP-ICU trial, and to explore any interactions between enteral nutrition and pharmacologic SUP on patient outcomes. The SUP-ICU trial dataset will be used to assess if enteral nutrition is associated with the outcomes of interest. Extended Cox models will be used considering relevant competing events, including treatment allocation (SUP or placebo) and enteral nutrition as a daily time-varying covariate, with additional adjustment for severity of illness (SAPS II). Results will be presented as adjusted hazard ratios for treatment allocation and enteral nutrition, and for treatment allocation and enteral nutrition considering potential interactions with the other variable, all with 95% confidence intervals and p-values for the tests of interaction. All results will be considered as exploratory only. This post hoc analysis may yield important insights to guide practice and inform the design of future randomised clinical trial investigating the effect of enteral nutrition on GI bleeding.

Abstract
BACKGROUND The number of burn patients over the age of 75 receiving advanced treatment, including extensive surgery and intensive care, is increasing. We aimed to describe the treatment and outcomes for burn patients over the age of 75 admitted to the National Burn Centre at Haukeland University Hospital. We also wanted to investigate whether frailty scores can be a predictor of the treatment outcome. MATERIAL AND METHOD All patients ≥ 75 years admitted to the National Burn Centre at Haukeland University Hospital in the period 2000-19 were included in the study. Frailty scores were calculated retrospectively based on patients' medical records. RESULTS Our study included 101 patients (50 women and 51 men). The number of admissions of older burn patients increased from an average of 3.3 per year in 2000-14 to 10.2 in the period 2015-19. The median total body surface area with burns was 11 % (range 0.9-80 %). Seventeen patients received palliative care, and 12 patients receiving active treatment died in hospital. In 68 of 84 (81 %) actively treated patients, tangential excision and split-thickness skin grafting were performed. The remainder received conservative treatment (non-surgical) with wound care and application of a silver dressing. Patients who died in hospital had a significantly higher total body surface area with burns (p < 0.0001) and higher frailty scores (p = 0.003) than patients who survived. INTERPRETATION The yearly number of patients over the age of 75 treated at the National Burn Centre tripled during the period. More than two-thirds of the patients were discharged alive. Extent of burn injury and frailty score are associated with mortality and may be useful for adjusting therapy.

Vasoactive and/or inotropic drugs in initial resuscitation of burn injuries: A systematic review. Acta Anaesthesiol Scand 2022; 66:795-802. [PMID: 35583993 PMCID: PMC9543770 DOI: 10.1111/aas.14095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Revised: 04/15/2022] [Accepted: 04/29/2022] [Indexed: 12/02/2022]
Abstract
BACKGROUND According to current guidelines, initial burn resuscitation should be performed with fluids alone. The aims of the study were to review the frequency of use of vasoactive and/or inotropic drugs in initial burn resuscitation, and assess the benefits and harms of adding such drugs to fluids. METHODS A systematic literature search was conducted in PubMed, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, UpToDate, and SveMed+ through 3 December 2021. The search included studies on critically ill burn patients receiving vasoactive and/or inotropic drugs in addition to fluids within 48 h after burn injury. RESULTS The literature search identified 1058 unique publications that were screened for inclusion. After assessing 115 publications in full text, only two retrospective cohort studies were included. One study found that 16 out of 52 (31%) patients received vasopressor(s). Factors associated with vasopressor use were increasing age, burn depth, and % total body surface area (TBSA) burnt. Another study observed that 20 out of 111 (18%) patients received vasopressor(s). Vasopressor use was associated with increasing age, Baux score, and %TBSA burnt in addition to more frequent dialysis treatment and increased mortality. Study quality assessed by the Newcastle-Ottawa quality assessment scale was considered good in one study, but uncertain due to limited description of methods in the other. CONCLUSION This systematic review revealed that there is a lack of evidence regarding the benefits and harms of using vasoactive and/or inotropic drugs in addition to fluids during early resuscitation of patients with major burns.

Abstract
COVID-19 infection primarily causes severe pneumonia complicated by acute respiratory distress syndrome and multiorgan failure requiring a ventilator support. We present a case of a 55-year-old male, admitted with COVID-19. He was obese but had no other medical conditions. His blood pressure was measured by his general physician on several occasions in the past, all values being normal (<140/90 mmHg). He developed multiorgan failure, requiring vasopressor and ventilator support for 17 days. A prone positioning improved the arterial oxygenation, and reduced the need for supplemental oxygen. After recovery, he showed persistently elevated blood pressure and sinus tachycardia both in clinic and out-of-clinic. The activation of the renin–angiotensin–aldosterone and sympathetic systems, volume-overload, hyperreninemia and cytokine storm might have contributed to the exaggerated cardiovascular response.

Abstract
Abstract
Background
It is unknown whether lung-protective ventilation is applied in burn patients and whether they benefit from it. This study aimed to determine ventilation practices in burn intensive care units (ICUs) and investigate the association between lung-protective ventilation and the number of ventilator-free days and alive at day 28 (VFD-28).
Methods
This is an international prospective observational cohort study including adult burn patients requiring mechanical ventilation. Low tidal volume (VT) was defined as VT ≤ 8 mL/kg predicted body weight (PBW). Levels of positive end-expiratory pressure (PEEP) and maximum airway pressures were collected. The association between VT and VFD-28 was analyzed using a competing risk model. Ventilation settings were presented for all patients, focusing on the first day of ventilation. We also compared ventilation settings between patients with and without inhalation trauma.
Results
A total of 160 patients from 28 ICUs in 16 countries were included. Low VT was used in 74% of patients, median VT size was 7.3 [interquartile range (IQR) 6.2–8.3] mL/kg PBW and did not differ between patients with and without inhalation trauma (p = 0.58). Median VFD-28 was 17 (IQR 0–26), without a difference between ventilation with low or high VT (p = 0.98). All patients were ventilated with PEEP levels ≥5 cmH2O; 80% of patients had maximum airway pressures <30 cmH2O.
Conclusion
In this international cohort study we found that lung-protective ventilation is used in the majority of burn patients, irrespective of the presence of inhalation trauma. Use of low VT was not associated with a reduction in VFD-28.

Abstract
AbstractBackgroundIt has been demonstrated that medical students are capable of learning microsurgical techniques. We hypothesize that microsurgical training might give insight into the importance of delicate tissue handling and correct knot tying that could have a positive influence on macrosurgical skills. The primary aim of this study was to evaluate the effect of microsurgical training on macrosurgical suturing skills in novice medical students.Subjects and methodsIn 2018, 46 novice medical students were enrolled and randomized into two groups. The intervention group received both macro- and microsurgical training and the control group received only microsurgical training. Both groups underwent an assessment test that consisted of macrosurgical tasks of three simple interrupted sutures with a square knot and continuous three-stitch long over-and-over sutures. These tests were individually filmed and assessed using the University of Bergen suturing skills assessment tool (UBAT) and the Objective Structured Assessment of Technical Skill global rating scale (OSATS). Questionnaires regarding future career ambitions and attitudes towards plastic surgery were also completed both prior to and following the tests.ResultsThe intervention group needed a longer time to complete the tasks than the control group (12.2 min vs. 9.6 min,p > 0.001), and scored lower on both the UBAT (5.6 vs. 9.0,p > 0.001) and the OSATS (11.1 vs. 13.1,p > 0.001) assessments. The microsurgery course tended to positively influence the students’ attitudes towards a career in plastic surgery (p = 0.002). This study demonstrates poorer macrosurgical skills in the medical students group exposed to microsurgical training. The true effect of microsurgical training warrants further investigation.Level of evidence: Level I, diagnostic study.

Abstract
Background Acute kidney injury (AKI) is a common complication in burn patients admitted to the intensive care unit (ICU) associated with increased morbidity and mortality. Our primary aim was to review incidence, risk factors, and outcomes of AKI in burn patients admitted to the ICU. Secondary aims were to review the use of renal replacement therapy (RRT) and impact on health care costs. Methods We conducted a systematic search in PubMed, UpToDate, and NICE through 3 December 2018. All reviews in Cochrane Database of Systematic Reviews except protocols were added to the PubMed search. We searched for studies on AKI according to Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE); Acute Kidney Injury Network (AKIN); and/or Kidney Disease: Improving Global Outcomes (KDIGO) criteria in burn patients admitted to the ICU. We collected data on AKI incidence, risk factors, use of RRT, renal recovery, length of stay (LOS), mortality, and health care costs. Results We included 33 observational studies comprising 8200 patients. Overall study quality, scored according to the Newcastle-Ottawa scale, was moderate. Random effect model meta-analysis revealed that the incidence of AKI among burn patients in the ICU was 38 (30–46) %. Patients with AKI were almost evenly distributed in the mild, moderate, and severe AKI subgroups. RRT was used in 12 (8–16) % of all patients. Risk factors for AKI were high age, chronic hypertension, diabetes mellitus, high Total Body Surface Area percent burnt, high Abbreviated Burn Severity Index score, inhalation injury, rhabdomyolysis, surgery, high Acute Physiology and Chronic Health Evaluation II score, high Sequential Organ Failure Assessment score, sepsis, and mechanical ventilation. AKI patients had 8.6 (4.0–13.2) days longer ICU LOS and higher mortality than non-AKI patients, OR 11.3 (7.3–17.4). Few studies reported renal recovery, and no study reported health care costs. Conclusions AKI occurred in 38% of burn patients admitted to the ICU, and 12% of all patients received RRT. Presence of AKI was associated with increased LOS and mortality.

Abstract
BACKGROUND The aetiology and risk factors for clinically important gastrointestinal bleeding (CIB) in adult ICU patients may differ according to the onset of CIB, which could affect the balance between benefits and harms of stress ulcer prophylaxis (SUP). METHODS We assessed the time to CIB in the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) trial. We assessed if associations between baseline characteristics including allocation to SUP and CIB changed during time in the ICU, specifically in the later (after day 2) compared to the earlier (first 2 days) period, using Cox models adjusted for SAPS II and allocation to SUP. Additionally, we described baseline characteristics and CIB episodes stratified by earlier/later/no CIB and 90-day mortality status. RESULTS Clinically important gastrointestinal bleeding occurred in 110/3291 (3.3%) patients after a median of 6 (interquartile range 2-13) days; 25.5% of the episodes occurred early. Higher SAPS II was consistently associated with increased risk of CIB (hazard ratio (HR) 1.03, 95% confidence interval (CI) 1.01-1.05 in the earlier period vs HR 1.02, 95% CI 1.01-1.03 in the later period; P = .37); university hospital admission was associated with decreased risk of earlier CIB (HR 0.30, 95% CI 0.14-0.63); this significantly increased in the later period (to HR 0.85, 95% CI 0.53-1.37; P = .02). Patients with later compared to earlier CIB received more transfusions and had more diagnostic/therapeutic procedures for CIB. CONCLUSIONS Clinically important gastrointestinal bleeding mostly occurred more than 2 days after randomization. University hospital admission was associated with significantly decreased risk of CIB in the earlier period only.

Abstract
BACKGROUND The long-term effects of stress ulcer prophylaxis with pantoprazole are unknown in ICU patients. We report 1-year mortality outcome in the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) trial. METHODS In the SUP-ICU trial, acutely admitted adult ICU patients at risk of gastrointestinal bleeding were randomised to intravenous pantoprazole 40 mg vs placebo (saline) once daily during their ICU stay. We assessed mortality at 1 year and did sensitivity analyses according to the trial protocol and statistical analysis plan. RESULTS A total of 3261 of the 3291 patients with available data (99.1%) were followed up at 1 year after randomisation; 1635 were allocated to pantoprazole and 1626 to placebo. At 1 year after randomisation, 610 of 1635 patients (37.3%) had died in the pantoprazole group as compared with 601 of 1626 (37.0%) in the placebo group (relative risk, 1.01; 95% confidence interval 0.92-1.10). The results were consistent in the sensitivity analysis adjusted for baseline risk factors and in those of the per-protocol population. We did not observe heterogeneity in the effect of pantoprazole vs placebo on 1-year mortality in the predefined subgroups, that is, patients with and without shock, mechanical ventilation, liver disease, coagulopathy, high disease severity (SAPS II > 53) or in medical vs surgical ICU patients. CONCLUSION We did not observe a difference in 1-year mortality among acutely admitted adult ICU patients with risk factors for gastrointestinal bleeding allocated to stress ulcer prophylaxis with pantoprazole or placebo during the ICU stay. (The SUP-ICU trial was funded by Innovation Fund Denmark and others; ClinicalTrials.gov number, NCT02467621).

Abstract
BACKGROUND Intensive care unit (ICU) patients with acute kidney injury requiring renal replacement therapy (RRT) are considered at high risk of gastrointestinal (GI) bleeding and stress ulcer prophylaxis (SUP) is often prescribed. We aimed to assess the incidence of GI bleeding and effects of SUP in these patients. METHODS We assessed GI bleeding in ICU patients receiving RRT at baseline (and at any time in the ICU) and effects of prophylactic pantoprazole versus placebo in the international SUP in the ICU (SUP-ICU) trial. All analyses were conducted according to a published protocol and statistical analysis plan. RESULTS Data of 3,291 acutely admitted adult ICU patients with one or more risk factors for GI bleeding randomized to pantoprazole or placebo intravenously once daily during ICU stay (until ICU discharge, death, or a maximum of 90 days) were analyzed. Some 20 out of 258 (7.8%, 95% CI 4.5-11.1%) and 52 out of 568 (9.2%, 95% CI 6.8-11.6%) of the patients receiving RRT at baseline and at any time in ICU, respectively, developed clinically important GI bleeding in the ICU. We did not observe statistically significant differences in the intervention effect (pantoprazole vs. placebo) in the proportion of patients with clinically important GI bleeding, clinically important events, infectious adverse events, use of interventions to stop GI bleeding, or 90-day mortality in patients with versus without RRT at baseline. CONCLUSIONS In adult ICU patients receiving RRT at baseline, we observed high incidences of clinically important GI bleeding, but did not observe effects of pantoprazole versus placebo in this subgroup.

Abstract
Unsubstantiated penicillin-allergy labels are common in surgical patients, and can lead to significant harm through avoidance of best first-line prophylaxis of surgical site infections and increased infection with resistant bacterial strains. Up to 98% of penicillin-allergy labels are incorrect when tested. Because of the scarcity of trained allergists in all healthcare systems, only a minority of surgical patients have the opportunity to undergo testing and de-labelling before surgery. Testing pathways can be modified and shortened in selected patients. A variety of healthcare professionals can, with appropriate training and in collaboration with allergists, provide testing for selected patients. We review how patients might be assessed, the appropriate testing strategies that can be used, and the minimum standards of safe testing.

Abstract
BAKGRUNN I 2002 ble Forskerlinjen opprettet for tidlig å rekruttere medisinstudenter til forskning. Vi ønsket å kartlegge hvor mange tidligere forskerlinjestudenter fra Universitetet i Bergen som fortsatte å forske og identifisere faktorer som var assosiert med videre forskning. MATERIALE OG METODE Alle studenter innrullert i forskerlinjeprogrammet ved Universitetet i Bergen siden oppstart i 2002 som var uteksaminert fra medisinstudiet innen juni 2017 ble kontaktet per e-post med en elektronisk spørreundersøkelse. Vi undersøkte om deltagerne holdt på med eller hadde gjennomført doktorgrad, antall publiserte artikler, tid siden siste publisering, akademisk undervisning og veiledning samt nåværende stilling på universitet eller høyskole. RESULTATER Totalt 102 av 148 (69 %) besvarte spørreundersøkelsen. Av disse hadde 68 % gått videre med doktorgrad, 38 % var involvert i akademisk undervisning eller veiledning og 29 % var ansatt i en akademisk stilling. Samlet hadde deltagerne i median publisert fire artikler. Kvinner hadde større sannsynlighet for å gå videre med doktorgrad enn menn. Det samme hadde de som publiserte minst én artikkel før fullført medisinstudium, og de som ikke hadde mottatt regelmessig veiledning som forskerlinjestudent. Det var ingen sammenheng mellom det å fullføre Forskerlinjen og det å gå videre med doktorgrad. FORTOLKNING Mange medisinstudenter som har gått Forskerlinjen ved Universitetet i Bergen fortsetter med forskning etter fullført studium. Dette gjelder også de som ikke fullfører linjen.

Iatrogenic cerebral gas embolism-A systematic review of case reports. Acta Anaesthesiol Scand 2019; 63:154-160. [PMID: 30203491 DOI: 10.1111/aas.13260] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Revised: 07/24/2018] [Accepted: 08/06/2018] [Indexed: 12/21/2022]
Abstract
BACKGROUND Cerebral gas embolism is a complication of several medical procedures and occurs when gas enters the cerebral circulation. Knowledge about etiology and outcome in affected patients is limited, and prospective trials on management and treatment are hardly feasible. Case reports are therefore an important source of information. METHODS A systematic literature search was conducted in June 2016 and May 2018, supplemented by a manual search. Titles and abstracts were systematically assessed for eligibility, followed by full-text screening for included papers. Screening and data extraction were performed independently by two researchers. Cases of cerebral gas embolism due to any iatrogenic cause were included. Criteria for exclusion were: animal studies, non-cerebral localization, extravascular gas only, and non-iatrogenic causes. 264 cases reported in 189 papers were included. RESULTS A broad range of procedures leading to iatrogenic cerebral gas embolism (ICGE) were identified and a comprehensive list is presented in this article. Procedures were mostly reported as conducted correctly, but procedure related error, patient activity, or defective equipment were also reported as causes. Neurological, neuropsychological, and cardiopulmonary symptoms were common. The diagnosis was frequently based on or confirmed by radiology, usually CT. Hyperbaric oxygen therapy was applied in a large number of cases. CONCLUSION The reported causes, symptoms and signs, and outcomes of ICGE vary significantly, and awareness of the condition in the medical community is essential. A standardized method of reporting could facilitate higher quality research in the field.

Abstract
Background Studies show increased mortality among severely injured patients not met by trauma team. Proper triage is important to ensure that all severely injured patients receive vital trauma care. In 2017 a new national trauma plan was implemented in Norway, which recommended the use of a modified version of “Guidelines for Field Triage of Injured Patients” to identify severely injured patients. Methods A retrospective study of 30,444 patients admitted to Haukeland University Hospital in 2013, with ICD-10 injury codes upon discharge. The exclusion criteria were department affiliation considered irrelevant when identifying trauma, patients with injuries that resulted in Injury Severity Score < 15, patients that did receive trauma team, and patients admitted > 24 h after time of injury. Information from patient records of every severely injured patient admitted in 2013 was obtained in order to investigate the sensitivity of the new guidelines. Results Trauma team activation was performed in 369 admissions and 85 patients were identified as major trauma. Ten severely injured patients did not receive trauma team resuscitation, resulting in an undertriage of 10.5%. Nine out of ten patients were men, median age 54 years. Five patients were 60 years or older. All of the undertriaged patients experienced fall from low height (< 4 m). Traumatic brain injury was seen in six patients. Six patients had a Glasgow Coma Scale score ≤ 13. The new trauma activation guidelines had a sensitivity of 95.0% in our 2013 trauma population. The degree of undertriage could have been reduced to 4.0% had the guidelines been implemented and correctly applied. Conclusions The rate of undertriage at Haukeland University Hospital in 2013 was above the recommendations of less than 5%. Use of the new trauma guidelines showed increased triage precision in the present trauma population.

Abstract
BACKGROUND Critically ill patients are at risk of gastrointestinal bleeding, but clinically important gastrointestinal bleeding is rare. The majority of intensive care unit (ICU) patients receive stress ulcer prophylaxis (SUP), despite uncertainty concerning the balance between benefit and harm. For approximately half of ICU patients with gastrointestinal bleeding, onset is early, ie within the first two days of the ICU stay. The aetiology of gastrointestinal bleeding and consequently the balance between benefit and harm of SUP may differ between patients with early vs late gastrointestinal bleeding. METHODS This is a protocol and statistical analysis plan for a preplanned exploratory substudy of the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) randomized clinical trial, comparing intravenous pantoprazole (40 mg once daily) with placebo in 3350 acutely ill adult ICU patients. We will describe baseline characteristics and assess the time to onset of the first clinically important episode of GI bleeding accounting for survival status and allocation to SUP or placebo. In addition, we will describe differences in therapeutic and diagnostic procedures used in patients with clinically important gastrointestinal bleeding according to early vs late bleeding and 90-day vital status. CONCLUSIONS The study outlined in this protocol will provide detailed information on patient characteristics and the timing of onset of gastrointestinal bleeding in the patients enrolled in the SUP-ICU trial. This may provide additional knowledge and incentives for future studies on which patients benefit from SUP.

Effects of stress ulcer prophylaxis in adult ICU patients receiving renal replacement therapy (Sup-Icu RENal, SIREN): Study protocol for a pre-planned observational study. Trials 2018; 19:26.

Abstract
Background Proton pump inhibitors are often used in critically ill patients to prevent gastrointestinal bleeding despite limited evidence for benefit. Patients with acute kidney injury requiring renal replacement therapy (RRT) are at high risk of gastrointestinal bleeding as (pre-)uremia induces coagulopathy through effects on platelets and coagulation cascades. No high-quality randomized clinical trials have previously assessed the benefits and harms of prophylactic proton pump inhibitor use in this high-risk population of adult critically ill patients. Methods/design Among the 3350 patients included in the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) trial—an investigator-initiated international randomized clinical trial on prophylactic proton pump inhibitor versus placebo in acutely admitted adult ICU patients at risk of gastrointestinal bleeding—we will compare the benefits and harms of prophylactic use of proton pump inhibitor in patients in need of RRT versus those not requiring this treatment. We will determine the proportion of patients with clinically important bleeding, the proportion of patients with adverse events including pneumonia, Clostridium difficile enteritis, or acute myocardial ischemia in the ICU, as well as transfusion requirements. Moreover, 90 day and 365 day mortality post-randomization will be investigated. As a secondary analysis, we will examine the association between acute kidney injury and RRT during ICU stay and gastrointestinal bleeding. Discussion With the outlined predefined analysis, we will characterize the balance between the benefits and harms of stress ulcer prophylaxis in acutely admitted adult ICU patients in need of RRT, including the potential interaction of allocation to proton pump inhibitor versus placebo.

Abstract
BACKGROUND The objective of this article is to elucidate the scope of burn injuries in Norway, on the basis of those patients who had sustained a burn injury that caused hospitalisation through a calendar year. MATERIAL AND METHOD The article is based on data retrieved from the Norwegian Patient Registry on patients discharged from Norwegian hospitals in 2012 with a burn injury as their main diagnosis, supplemented with activity data for children admitted to the Burn Unit, Haukeland University Hospital, Bergen, during the period 2013 – 15. RESULTS In 2012, altogether 620 people (12.4/100 000 inhabitants) were hospitalised with burn injuries. Of these patients, 393 (63.4 %) were men. A total of 375 patients (60 %) were hospitalised more than once, and 124 (20 %) were admitted to more than one hospital. Altogether 367 patients (59 %) were hospitalised for less than eight days. Average hospitalisation time for the group as a whole was 11.3 days (SD 18.8 days). Many of the burn-injured patients were young: the average age was 27.4 years (SD 26.0 years). As many as 183 patients (30 %) were less than three years old. Children in this age group were admitted for burn injuries 12 times more frequently than children ≥ 5 years and adults. INTERPRETATION We found no definite reduction in burn injuries as a cause for admission to Norwegian hospitals in 2012 when compared to results from previous studies for the period 1992 – 2007. There ought to be a major potential for more effective prevention of burn injuries in the age group < 3 years, in which scalding (78 %) and contact with hot surfaces (most often stoves) (17 %) are the main mechanisms of injury.

Abstract
Whole-saliva IgA appears like an attractive noninvasive readout for intestinal immune induction after enteric infection or vaccination, but has failed to show consistent correlation with established invasive markers and IgA in feces or intestinal lavage. For reference, we measured antibodies in samples from 30 healthy volunteers who were orally infected with wild-type enterotoxigenic Escherichia coli. The response against these bacteria in serum, lavage, and lymphocyte supernatants (antibody-in-lymphocyte-supernatant, ALS) was compared with that in targeted parotid and sublingual/submandibular secretions. Strong correlation occurred between IgA antibody levels against the challenge bacteria in sublingual/submandibular secretions and in lavage (r=0.69, P<0.0001) and ALS (r=0.70, P<0.0001). In sublingual/submandibular secretions, 93% responded with more than a twofold increase in IgA antibodies against the challenge strain, whereas the corresponding response in parotid secretions was only 67% (P=0.039). With >twofold ALS as a reference, the sensitivity of a >twofold response for IgA in sublingual/submandibular secretion was 96%, whereas it was only 67% in the parotid fluid. To exclude that flow rate variations influenced the results, we used albumin as a marker. Our data suggested that IgA in sublingual/submandibular secretions, rather than whole saliva with its variable content of parotid fluid, is a preferential noninvasive proxy for intestinal immune induction.

Abstract
BACKGROUND & AIMS This review aims to clarify the use of indirect calorimetry (IC) in nutritional therapy for critically ill and other patient populations. It features a comprehensive overview of the technical concepts, the practical application and current developments of IC. METHODS Pubmed-referenced publications were analyzed to generate an overview about the basic knowledge of IC, to describe advantages and disadvantages of the current technology, to clarify technical issues and provide pragmatic solutions for clinical practice and metabolic research. The International Multicentric Study Group for Indirect Calorimetry (ICALIC) has generated this position paper. RESULTS IC can be performed in in- and out-patients, including those in the intensive care unit, to measure energy expenditure (EE). Optimal nutritional therapy, defined as energy prescription based on measured EE by IC has been associated with better clinical outcome. Equations based on simple anthropometric measurements to predict EE are inaccurate when applied to individual patients. An ongoing international academic initiative to develop a new indirect calorimeter aims at providing innovative and affordable technical solutions for many of the current limitations of IC. CONCLUSION Indirect calorimetry is a tool of paramount importance, necessary to optimize the nutrition therapy of patients with various pathologies and conditions. Recent technical developments allow broader use of IC for in- and out-patients.

Stress ulcer prophylaxis with a proton pump inhibitor versus placebo in critically ill patients (SUP-ICU trial): study protocol for a randomised controlled trial. Trials 2016; 17:205.

Abstract
Background Critically ill patients in the intensive care unit (ICU) are at risk of clinically important gastrointestinal bleeding, and acid suppressants are frequently used prophylactically. However, stress ulcer prophylaxis may increase the risk of serious adverse events and, additionally, the quantity and quality of evidence supporting the use of stress ulcer prophylaxis is low. The aim of the SUP-ICU trial is to assess the benefits and harms of stress ulcer prophylaxis with a proton pump inhibitor in adult patients in the ICU. We hypothesise that stress ulcer prophylaxis reduces the rate of gastrointestinal bleeding, but increases rates of nosocomial infections and myocardial ischaemia. The overall effect on mortality is unpredictable. Methods/design The SUP-ICU trial is an investigator-initiated, pragmatic, international, multicentre, randomised, blinded, parallel-group trial of stress ulcer prophylaxis with a proton pump inhibitor versus placebo (saline) in 3350 acutely ill ICU patients at risk of gastrointestinal bleeding. The primary outcome measure is 90-day mortality. Secondary outcomes include the proportion of patients with clinically important gastrointestinal bleeding, pneumonia, Clostridium difficile infection or myocardial ischaemia, days alive without life support in the 90-day period, serious adverse reactions, 1-year mortality, and health economic analyses. The sample size will enable us to detect a 20 % relative risk difference (5 % absolute risk difference) in 90-day mortality assuming a 25 % event rate with a risk of type I error of 5 % and power of 90 %. The trial will be externally monitored according to Good Clinical Practice standards. Interim analyses will be performed after 1650 and 2500 patients. Conclusion The SUP-ICU trial will provide high-quality data on the benefits and harms of stress ulcer prophylaxis with a proton pump inhibitor in critically ill adult patients admitted in the ICU. Trial registration ClinicalTrials.gov Identifier: NCT02467621.

Abstract
PURPOSE OF REVIEW Resting energy expenditure in critically ill patients is highly variable depending on the diagnoses, illness severity, nutritional status, and treatments. The main questions are the following: What is the optimal energy target in my critically ill patient in the ICU at a given time point of the ICU stay? Is measured energy expenditure equivalent with energy requirement? RECENT FINDINGS There is uncertainty on the best way to feed the ICU patient; when to start, and what to give, especially concerning the amount of energy. Recent studies indicate that outcome is dependent on provision, components, and route. Indirect calorimetry is considered the gold standard to measure energy requirement and cannot be replaced by assumptions based on weight, height, sex, age, or minute ventilation. A main concern is that an indirect calorimeter with appropriate specifications to a reasonable cost is not available in the market. There are initiatives to solve this matter. SUMMARY Nutritionists, intensive care doctors, researchers, and innovators must collaborate to develop an indirect calorimeter to a reasonable cost (less than 10,000 €) that is accurate and handy in the clinical setting. Since this instrument is not yet available, clinicians are left with good clinical practice and predictive formulas.

Abstract
BACKGROUND/OBJECTIVES Malnutrition is present in 20-50% of hospitalized patients, and nutritional care is a challenge. The aim was to evaluate whether the implementation of a nutritional strategy would influence nutritional care performance in a university hospital. SUBJECTS/METHODS This was a prospective quality improvement program implementing guidelines for nutritional care, with the aim of improving nutritional practice. The Nutrition Risk Screening (NRS) 2002 was used. Point prevalence surveys over 2 years to determine whether nutritional practice had improved. RESULTS In total, 3604 (70%) of 5183 eligible patients were screened and 1230 (34%) were at nutritional risk. Only 53% of the at-risk patients got nutritional treatment and 5% were seen by a dietician. The proportion of patients screened increased from the first to the eighth point prevalence survey (P=0.012), but not the proportion of patients treated (P=0.66). The four initial screening questions in NRS 2002 identified 92% of the patients not at nutritional risk. CONCLUSIONS Implementation of nutritional guidelines improved the screening performance, but did not increase the proportion of patients who received nutritional treatment. Point prevalence surveys were useful to evaluate nutritional practice in this university hospital. In order to improve practice, we suggest using only the four initial screening questions in NRS 2002 to identify patients not at risk, better education in nutritional care for physicians and nurses, and more dieticians employed. Audit of implementation of guidelines, performed by health authorities, and specific reimbursement for managing nutrition may also improve practice.

Abstract
BACKGROUND Low plasma glutamine concentration is an independent prognostic factor for an unfavourable outcome in the intensive care unit (ICU). Intravenous (i.v.) supplementation with glutamine is reported to improve outcome. In a multi-centric, double-blinded, controlled, randomised, pragmatic clinical trial of i.v. glutamine supplementation for ICU patients, we investigated outcomes regarding sequential organ failure assessment (SOFA) scores and mortality. The hypothesis was that the change in the SOFA score would be improved by glutamine supplementation. METHODS Patients (n=413) given nutrition by an enteral and/or a parenteral route with the aim of providing full nutrition were included within 72 h after ICU admission. Glutamine was supplemented as i.v. l-alanyl-l-glutamine, 0.283 g glutamine/kg body weight/24 h for the entire ICU stay. Placebo was saline in identical bottles. All included patients were considered as intention-to-treat patients. Patients given supplementation for >3 days were considered as predetermined per protocol (PP) patients. RESULTS There was a lower ICU mortality in the treatment arm as compared with the controls in the PP group, but not at 6 months. For change in the SOFA scores, no differences were seen, 1 (0,3) vs. 2 (0.4), P=0.792, for the glutamine group and the controls, respectively. CONCLUSION In summary, a reduced ICU mortality was observed during i.v. glutamine supplementation in the PP group. The pragmatic design of the study makes the results representative for a broad range of ICU patients.

Abstract
Background By tradition colloid solutions have been used to obtain fast circulatory stabilisation in shock, but high molecular weight hydroxyethyl starch (HES) may cause acute kidney failure in patients with severe sepsis. Now lower molecular weight HES 130/0.4 is the preferred colloid in Scandinavian intensive care units (ICUs) and 1st choice fluid for patients with severe sepsis. However, HES 130/0.4 is largely unstudied in patients with severe sepsis. Methods/Design The 6S trial will randomise 800 patients with severe sepsis in 30 Scandinavian ICUs to masked fluid resuscitation using either 6% HES 130/0.4 in Ringer's acetate or Ringer's acetate alone. The composite endpoint of 90-day mortality or end-stage kidney failure is the primary outcome measure. The secondary outcome measures are severe bleeding or allergic reactions, organ failure, acute kidney failure, days alive without renal replacement therapy or ventilator support and 28-day and 1/2- and one-year mortality. The sample size will allow the detection of a 10% absolute difference between the two groups in the composite endpoint with a power of 80%. Discussion The 6S trial will provide important safety and efficacy data on the use of HES 130/0.4 in patients with severe sepsis. The effects on mortality, dialysis-dependency, time on ventilator, bleeding and markers of resuscitation, metabolism, kidney failure, and coagulation will be assessed.

Abstract
BACKGROUND Treatment of patients with large burns is challenging. MATERIAL AND METHOD The article is based on clinical experience, and a non-systematic review in PubMed. RESULTS In patients with burns covering more than 10 - 15 % of the total body surface area, fluid resuscitation should be initiated early. Fluid induces edema, and facial burns may necessitate early orotracheal intubation to secure the airways. Reduced ventilation and-/or peripheral circulation due to deep burns should be managed by early escharotomy (and, more seldom, fasciotomy) at the primary hospital. Respiratory distress is most often due to vigorous fluid resuscitation, secretions, pneumonia and-/or sepsis. Fiber bronchoscopy may reveal inhalation injury and enables removal of secreted material from the airways. In the acute initial phase, hypotension is usually caused by hypovolemia. Subsequently a massive inflammatory response (SIRS) causes vasodilatation, hypotension and increased cardiac output. Wound and airway infections are common. SIRS may cause CRP levels above 100 and a body temperature of 38 - 39 degrees C, which makes it difficult to find the right time to start antibiotic treatment. Nevertheless, prophylactic use of antibiotics is not encouraged. Definitive surgery, excision and transplantation, should be performed early, preferably within the first week. INTERPRETATION Patients with large burns should be treated according to general principles for intensive medical care, preferably in units with special experience in treatment of burns.

Capillary leakage in post-cardiac arrest survivors during therapeutic hypothermia - a prospective, randomised study. Scand J Trauma Resusc Emerg Med 2010; 18:29. [PMID: 20500876 PMCID: PMC2890528 DOI: 10.1186/1757-7241-18-29] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2010] [Accepted: 05/25/2010] [Indexed: 12/24/2022] Open
Abstract
Background Fluids are often given liberally after the return of spontaneous circulation. However, the optimal fluid regimen in survivors of cardiac arrest is unknown. Recent studies indicate an increased fluid requirement in post-cardiac arrest patients. During hypothermia, animal studies report extravasation in several organs, including the brain. We investigated two fluid strategies to determine whether the choice of fluid would influence fluid requirements, capillary leakage and oedema formation. Methods 19 survivors with witnessed cardiac arrest of primary cardiac origin were allocated to either 7.2% hypertonic saline with 6% poly (O-2-hydroxyethyl) starch solution (HH) or standard fluid therapy (Ringer's Acetate and saline 9 mg/ml) (control). The patients were treated with the randomised fluid immediately after admission and continued for 24 hours of therapeutic hypothermia. Results During the first 24 hours, the HH patients required significantly less i.v. fluid than the control patients (4750 ml versus 8010 ml, p = 0.019) with comparable use of vasopressors. Systemic vascular resistance was significantly reduced from 0 to 24 hours (p = 0.014), with no difference between the groups. Colloid osmotic pressure (COP) in serum and interstitial fluid (p < 0.001 and p = 0.014 respectively) decreased as a function of time in both groups, with a more pronounced reduction in interstitial COP in the crystalloid group. Magnetic resonance imaging of the brain did not reveal vasogenic oedema. Conclusions Post-cardiac arrest patients have high fluid requirements during therapeutic hypothermia, probably due to increased extravasation. The use of HH reduced the fluid requirement significantly. However, the lack of brain oedema in both groups suggests no superior fluid regimen. Cardiac index was significantly improved in the group treated with crystalloids. Although we do not associate HH with the renal failures that developed, caution should be taken when using hypertonic starch solutions in these patients. Trial registration NCT00347477.

Abstract
BACKGROUND Local anaesthetics (LA) are generally considered safe with respect to allergy. However, various clinical reactions steadily occur. Even though most reactions are manifestations of reflexes to perceptive stimuli, uncertainty often remains regarding a possible allergic mechanism. This uncertainty later leads to an avoidance of local anaesthesia and unnecessarily painful interventions, resource-consuming general anaesthesia or even the risk of re-exposure to other yet unidentified allergens. In the present study, follow-up procedures at an allergy clinic were analysed to examine the frequency of identified causative agents and pathogenetic mechanisms and evaluate the strength of the diagnostic conclusions. METHOD The medical records of 135 cases with alleged allergic reactions to LA were reviewed. Diagnoses were based on case histories, skin tests, subcutaneous challenge tests and in vitro IgE analyses. RESULTS Two events (1.5%) were diagnosed as hypersensitivity to LA, articaine-adrenaline and tetracaine-adrenaline, respectively. Ten reactions (7%) were diagnosed as IgE-mediated allergy to other substances including chlorhexidine, latex, triamcinolone and possibly hexaminolevulinate. As challenge testing was not consistently performed with the culprit LA compound, follow-ups were short of definitely refuting hypersensitivity in 61% of the cases. The reported clinical manifestations were in general diagnostically unspecific, but itch and generalised urticaria were most frequent in test-positive cases. CONCLUSION Reactions during local anaesthesia are rarely found to be an IgE-mediated LA allergy. Whenever the clinical picture is compatible with allergy, other allergens should also be tested.

Abstract
BACKGROUND The aim of this study was to test, on a multinational level, the pholcodine (PHO) hypothesis, i.e. that the consumption of PHO-containing cough mixtures could cause higher prevalence of IgE antibodies to PHO, morphine (MOR) and suxamethonium (SUX). As a consequence the risk of anaphylaxis to neuromuscular blocking agents (NMBA) will be increased. METHODS National PHO consumptions were derived from the United Nations International Narcotics Control Board (INCB) database. IgE and IgE antibodies to PHO, MOR, SUX and P-aminophenyl-phosphoryl choline (PAPPC) were measured in sera from atopic individuals, defined by a positive Phadiatop test (>0.35 kU(A)/l), collected in nine countries representing high and low PHO-consuming nations. RESULTS There was a significant positive association between PHO consumption and prevalences of IgE-sensitization to PHO and MOR, but not to SUX and PAPPC, as calculated both by exposure group comparisons and linear regression analysis. The Netherlands and the USA, did not have PHO-containing drugs on the markets, although the former had a considerable PHO consumption. Both countries had high figures of IgE-sensitization. CONCLUSION This international prevalence study lends additional support to the PHO hypothesis and, consequently, that continued use of drugs containing this substance should be seriously questioned. The results also indicate that other, yet unknown, substances may lead to IgE-sensitization towards NMBAs.

Abstract
BACKGROUND Anaphylaxis is a serious life-threatening generalized or systemic hypersensitivity reaction. The aim of this paper is to provide knowledge on how to diagnose, treat and follow up patients with suspected anaphylaxis during general and local anaesthesia. MATERIAL AND METHODS The article is based on literature identified through a non-systematic search in PubMed, the Scandinavian Guidelines on anaphylaxis during anaesthesia and on own research. RESULTS Anaphylactic symptoms during anaesthesia vary with respect to severity. Manifestations from skin and the cardiovascular and respiratory systems are present simultaneously in approximately 70 % of patients. Early treatment with adrenaline, fluid and extra oxygen may be vital for survival without sequelae. The following patients should be assessed before anaesthesia: those with moderate or serious reactions or with reactions that raise suspicion of allergy which may cause problems in connection with future treatment. Neuromuscular blocking agents are the main cause of IgE-mediated anaphylaxis during anaesthesia in Norway. New research has shown that allergy towards neuromuscular blocking agents can develop after ingestion of cough syrup containing pholcodine (stimulates asymptomatic production of antibodies). These antibodies cause cross-sensibilisation with neuromuscular blocking agents. The cough syrup Tuxi was withdrawn from the Norwegian market during spring 2007. INTERPRETATION Allergic reactions during anaesthesia are rare and potentially life-threatening; patients should be followed up and treated in a standardized way.
