Lung ultrasound predicts well extravascular lung water but is of limited usefulness in the prediction of wedge pressure.

BACKGROUND: Pulmonary congestion is indicated at lung ultrasound by detection of B-lines, but correlation of these ultrasound signs with pulmonary artery occlusion pressure (PAOP) and extravascular lung water (EVLW) still remains to be further explored. The aim of the study was to assess whether B-lines, and eventually a combination with left ventricular ejection fraction (LVEF) assessment, are useful to differentiate low/high PAOP and EVLW in critically ill patients. METHODS: The authors enrolled 73 patients requiring invasive monitoring from the intensive care unit of four university-affiliated hospitals. Forty-one patients underwent PAOP measurement by pulmonary artery catheterization and 32 patients had EVLW measured by transpulmonary thermodilution method. Lung and cardiac ultrasound examinations focused to the evaluation of B-lines and gross estimation of LVEF were performed. The absence of diffuse B-lines (A-pattern) versus the pattern showing prevalent B-lines (B-pattern) and the combination with normal or impaired LVEF were correlated with cutoff levels of PAOP and EVLW. RESULTS: PAOP of 18 mmHg or less was predicted by the A-pattern with 85.7% sensitivity (95% CI, 70.5 to 94.1%) and 40.0% specificity (CI, 25.4 to 56.4%), whereas EVLW 10 ml/kg or less with 81.0% sensitivity (CI, 62.6 to 91.9%) and 90.9% specificity (CI, 74.2 to 97.7%). The combination of A-pattern with normal LVEF increased sensitivity to 100% (CI, 84.5 to 100%) and specificity to 72.7% (CI, 52.0 to 87.2%) for the prediction of PAOP 18 mmHg or less. CONCLUSIONS: B-lines allow good prediction of pulmonary congestion indicated by EVLW, whereas are of limited usefulness for the prediction of hemodynamic congestion indicated by PAOP. Combining B-lines with estimation of LVEF at transthoracic ultrasound may improve the prediction of PAOP.

Incidence and outcome of in-hospital cardiac arrest in Italy: a multicentre observational study in the Piedmont Region.

AIMS: to report the incidence, characteristics, and outcome of in-hospital cardiac arrest (IHCA) in a large Italian region. SETTING: all hospitals participating in the IHCA Registry Initiative of Piedmont. METHODS: observational cohort study in adult (>18year old) inpatients resuscitated from IHCA during three consecutive years (2012-2014). The main outcome measures were IHCA incidence and survival to hospital discharge. RESULTS: A total of1539 arrests in adult inpatients were recorded in the study period, yielding an overall incidence of 1.51 arrests/1000 admissions. The incidence was highest at day 1 after hospital admission and in the morning hours, with a peak at 9.00 a.m. Median age was 77 (interquartile range 68-83) years. The presenting rhythm was ventricular fibrillation/pulseless ventricular tachycardia in 291/1539 (18.9%) cases. A total of 549/1539 (35.7%) patients achieved recovery of spontaneous circulation (ROSC) and 228/1539(14.8%) survived hospital discharge, with 207 (90.8%) of the latter having good neurological outcome (Cerebral Performance Categories [CPC] 1 or 2).After adjustment for major confounders, a pre-arrest CPC=1, a cardiac cause of arrest, a shockable presenting rhythm, and a shorter duration of resuscitation were independently associated with a higher likelihood of survival to discharge. CONCLUSIONS: in this Italian registry the incidence of IHCA and its circadian distribution were comparable to those in the NCAA registry in the UK. Patients were older and had a lower ROSC rate than these observed in other large IHCA registries, but post-ROSC survival rate and factors affecting survival to discharge were similar.

A family information brochure and dedicated website to improve the ICU experience for patients' relatives: an Italian multicenter before-and-after study.

PURPOSE: Good communication between ICU staff and patients' relatives may reduce the occurrence of post-traumatic stress disorder, anxiety or depression, and dissatisfaction with clinicians. An information brochure and website to meet relatives' needs were designed to explain in technical yet simple terms what happens during and after an ICU stay, to legitimize emotions such as fear, apprehension, and suffering, and to improve cooperation with relatives without increasing staff workload. The main outcomes were improved understanding of prognosis and procedures, and decrease of relatives' anxiety, depression, and stress symptoms. METHODS: In this prospective multicenter before-and-after study, a self-administered questionnaire was used to investigate relatives' understanding of prognosis, treatments, and organ dysfunction, families' satisfaction, and symptoms of anxiety, depression, and post-traumatic stress. RESULTS: A total of 551 relatives received questionnaires in nine Italian ICUs; 332 (60%) responded, 144 before and 179 after implementation of the brochure and website. Of the 179 relatives who responded after, 131 (73%) stated they had read the brochure and 34 (19%) reported viewing the website. The intervention was associated with increased correct understanding of the prognosis (from 69 to 84%, p = 0.04) and the therapeutic procedures (from 17 to 28%, p = 0.03). Multivariable analysis, together with non-modifiable factors (relative's gender, education level, relationship to patient, and patient status at ICU discharge), showed the intervention to be significantly associated with a lower incidence of post-traumatic stress symptoms (Poisson coefficient = -0.29, 95% CI -0.52/-0.07). The intervention had no effect on the prevalence of symptoms of anxiety and depression. CONCLUSION: An information brochure and website designed to meet relatives' needs improved family members' comprehension and reduced their prevalence of stress symptoms.

Ethical issues associated with in-hospital emergency from the Medical Emergency Team's perspective: a national survey.

BACKGROUND: Medical Emergency Teams (METs) are frequently involved in ethical issues associated to in-hospital emergencies, like decisions about end-of-life care and intensive care unit (ICU) admission. MET involvement offers both advantages and disadvantages, especially when an immediate decision must be made. We performed a survey among Italian intensivists/anesthesiologists evaluating MET's perspective on the most relevant ethical aspects faced in daily practice. METHODS: A questionnaire was developed on behalf of the Italian scientific society of anesthesia and intensive care (SIAARTI) and administered to its members. Decision making criteria applied by respondents when dealing with ethical aspects, the estimated incidence of conflicts due to ethical issues and the impact on the respondents' emotional and moral distress were explored. RESULTS: The questionnaire was completed by 327 intensivists/anesthesiologists. Patient life-expectancy, wishes, and the quality of life were the factors most considered for decisions. Conflicts with ward physicians were reported by most respondents; disagreement on appropriateness of ICU admission and family unpreparedness to the imminent patient death were the most frequent reasons. Half of respondents considered that in case of conflicts the final decision should be made by the MET. Conflicts were generally recognized as causing increased and moral distress within the MET members. Few respondents reported that dedicated protocols or training were locally available. CONCLUSION: Italian intensivists/anesthesiologists reported that ethical issues associated with in-hospital emergencies are occurring commonly and are having a significant negative impact on MET well-being. Conflicts with ward physicians happen frequently. They also conveyed that hospitals don't offer ethics training and have no protocols in place to address ethical issues.

Early rehabilitation for severe acquired brain injury in intensive care unit: multicenter observational study.

BACKGROUND: The increased survival after a severe acquired brain injury (sABI) raise the problem of making most effective the treatments in Intensive Care Unit (ICU)/Neurointensive Care Unit (NICU), also integrating rehabilitation care. Despite previous studies reported that early mobilization in ICU was effective in preventing complications and reducing hospital stay, few studies addressed the rehabilitative management of sABI patients in ICU/NICU. AIM: To collect clinical and functional data about the early rehabilitative management of sABI patients during ICU/NICU stay. DESIGN: Prospective, observational, multicenter study. SETTING: Fourteen facilities supplied by intensive neurorehabilitation units and ICU/NICUs. POPULATION: Consecutive sABI patients admitted to ICU/NICU. METHODS: Patients were evaluated at admission and then every 3-5 days. Clinical, functional and rehabilitative data, including Glasgow Coma Scale (GCS), Disability Rating Scale (DRS), The Rancho Los Amigos Levels of Cognitive Functioning Scale (LCF), Early Rehabilitation Barthel Index (ERBI), Glasgow Outcome scale (GOS) and Functional Independence Measure (FIM) were collected. RESULTS: One hundred and two patients (F/M 44/58) were enrolled. The mean duration of ICU stay was 24.7±13.9 days and the first rehabilitative evaluation occurred after 8.7±8.8 days. Regular postural changes and multijoint mobilization were prescribed in 63.7% and 64.7% cases, respectively. The mean session duration was 38±11.5 minutes. Swallowing evaluation was performed in 14.7% patients, psychological support was provided to 12.7% of patients' caregivers, while 17.6% received a psycho-educational intervention, and 28.4% were involved in interdisciplinary team meetings. The main discharge destinations were Severe Acquired Brain Injury rehabilitation units for 43.7%, intensive neurorehabilitation units for 20.7%. CONCLUSIONS: Data showed that early rehabilitation was not diffusely performed in sABI subjects in ICU/NICU and rehabilitative interventions were variable; one-third of subjects were not referred to dedicated rehabilitation unit at discharge. CLINICAL REHABILITATION IMPACT: The study stresses the need to spread and implement a rehabilitative culture also for critical ill patients due to neurological diseases.

Factors affecting attitudes and barriers to a medical emergency team among nurses and medical doctors: a multi-centre survey.

AIM: To identify factors underlying attitudes towards the medical emergency team (MET) and barriers to its utilisation among ward nurses and physicians. METHODS: Multicentre survey using an anonymous questionnaire in hospitals with a fully operational MET system in the Piedmont Region, Italy. Response to questions was scored on a 5-point Likert-type agreement scale. Dichotomised results were included in a logistic regression model. RESULTS: Among 2279 staff members who were contacted, 1812 (79.6%) completed the survey. The vast majority of respondents valued the MET. Working in a surgical vs. medical ward and having participated in either the MET educational programme (METal course) or MET interventions were associated with better acceptance of the MET system. Reluctance by nurses to call the covering doctor first instead of the MET for deteriorating patients (62%) was significantly less likely in those working in surgical vs. medical wards or having a higher seniority or a METal certification (OR 0.51 [0.4-0.65], 0.69 [0.47-0.99], and 0.6 [0.46-0.79], respectively). Reluctance to call the MET in a patient fulfilling calling criteria (21%), was less likely to occur in medical doctors vs. nurses and in surgical vs. medical ward staff, and it was unaffected by the METal certification. CONCLUSIONS: The MET was well accepted in participating hospitals. Nurse referral to the covering physician was the major barrier to MET activation. Medical status, working in surgical vs. medical wards, seniority and participation in the METal educational programme were associated with lower likelihood of showing barriers to MET activation.

A case of unilateral re-expansion pulmonary oedema successfully treated with non-invasive continuous positive airway pressure.

Unilateral re-expansion pulmonary oedema is a rare threatening complication of the treatment of lung atelectasis, pleural effusion or pneumothorax, the pathogenesis of which is not completely known. The clinical picture varies considerably from asymptomatic radiological findings to dramatic respiratory failure with circulatory shock. There are few literature reports of the treatment of re-expansion pulmonary oedema with non-invasive continuous positive airway pressure. We present the case of a 75-year-old man who presented in our emergency room with a large left-sided spontaneous pneumothorax and developed severe respiratory failure and circulatory collapse after drainage via a chest tube. The diagnosis of unilateral re-expansion pulmonary oedema was made and he was successfully treated with non-invasive continuous positive airway pressure. Literature data about the aetiological and pathogenetic factors of the condition are also considered.
