ABSTRACT
AIM: To determine the type of airway devices used during in-hospital cardiac arrest (IHCA) resuscitation attempts. METHODS: International multicentre retrospective observational study of in-patients aged over 18 years who received chest compressions for cardiac arrest from April 2016 to September 2018. Patients were identified from resuscitation registries and rapid response system databases. Data were collected through review of resuscitation records and hospital notes. Airway devices used during cardiac arrest were recorded as basic (adjuncts or bag-mask), or advanced, including supraglottic airway devices, tracheal tubes or tracheostomies. Descriptive statistics and multivariable regression modelling were used for data analysis. RESULTS: The final analysis included 598 patients. No airway management occurred in 36 (6%), basic airway device use occurred at any time in 562 (94%), basic airway device use without an advanced airway device in 182 (30%), tracheal intubation in 301 (50%), supraglottic airway in 102 (17%), and tracheostomy in 1 (0.2%). There was significant variation in airway device use between centres. The intubation rate ranged between 21% and 90% while supraglottic airway use varied between 1% and 45%. The choice of tracheal intubation vs. supraglottic airway as the second advanced airway device was not associated with immediate survival from the resuscitation attempt (odds ratio 0.81; 95% confidence interval 0.35-1.8). CONCLUSION: There is wide variation in airway device use during resuscitation after IHCA. Only half of patients are intubated before return of spontaneous circulation and many are managed without an advanced airway. Further investigation is needed to determine optimal airway device management strategies during resuscitation following IHCA.

BACKGROUND: We aimed to determine the incidence of and associated risk factors for cardiopulmonary resuscitation (CPR)-related injuries in non-survivors of out-of-hospital cardiac arrests (OHCAs) in an emergency medical service (EMS) system in which all CPR procedures are performed on scene and patients are not routinely transported to the hospital with ongoing CPR. MATERIAL AND METHODS: We conducted this prospective observational study between 1 June 2013, and 31 May 2014. Data were collected from EMS datasheets and forensic autopsy records. The exclusion criteria were OHCAs due to trauma in the thoracic or abdominal area. EMS adhered to the European Resuscitation Council Resuscitation Guidelines (2010) during the resuscitation attempts. RESULTS: Emergency medical service provided CPR in 280 attended OHCAs with 207 cases terminated on scene. A total of 149 patients underwent a forensic autopsy and 47% had a CPR-related injury. The most common injuries were multiple rib fractures (43%), with 22% of patients having more than eight fractured ribs. Abdominal visceral injuries or injuries related to airway management were rare. The injuries were associated with older age, male gender, initial shockable rhythm and public location of the cardiac arrest (P < .05 respectively). In the multivariable regression analysis, older age, male gender, and public location were independent predictors for injuries. There were no differences in the durations of the CPR attempt between the injured and non-injured groups. CONCLUSION: Older age, male gender, and public location were independently associated with CPR-related injuries. The duration of the resuscitation attempts did not affect the incident of injuries.

BACKGROUND: Rapid response teams (RRTs) triage most patients to stay on ward, even though some of them have deranged vital signs according to RRTs themselves. We investigated the prevalence and outcome of this RRT patient cohort. METHODS: A prospective observational study was conducted in a Finnish tertiary referral centre, Tampere University Hospital. Data on RRT activations were collected between 1 May 2012 and 30 April 2015. Vital signs of patients triaged to stay on ward without treatment limitations were classified according to objective RRT trigger criteria observed during the reviews. RESULTS: During the study period, 860 patients had their first RRT review and were triaged to stay on ward. Of these, 564 (66%) had deranged vital signs, while 296 (34%) did not. RRT patients with deranged vital signs were of comparable age and comorbidity index as stable patients. Even though the patients with deranged vital signs had received RRT interventions, such as fluids and medications, more often than the stable patients, they required new RRT reviews more often and had higher in-hospital and 30-day mortality. Moreover, the former group had substantially higher 1-year mortality than the latter (37% vs. 29%, P = 0.014). In a multivariate regression analysis, deranged vital signs during RRT review was found to be independently associated with 30-day mortality (OR 1.74; 95% CI 1.12-2.70). CONCLUSION: Patients triaged to stay on ward despite deranged vital signs are high-risk patients who could benefit from routine follow-up by RRT nurses before they deteriorate beyond salvation.

Aiming to identify factors causing the adverse health effects associated with moisture-damaged indoor environments, we analyzed immunotoxicological potential of settled dust from moisture-damaged and reference schools in relation to their microbiological composition. Mouse RAW264.7 macrophages were exposed to settled dust samples (n = 25) collected from moisture-damaged and reference schools in Spain, the Netherlands, and Finland. After exposure, we analyzed production of inflammatory markers [nitric oxide (NO), tumor necrosis factor-α (TNF-)α, interleukin (IL)-6, and macrophage inflammatory protein (MIP)2] as well as mitochondrial activity, viability, apoptosis, and cell cycle arrest. Furthermore, particle counts, concentration of selected microbial groups as well as chemical markers such as ergosterol, 3-hydroxy fatty acids, muramic acid, endotoxins, and glucans were measured as markers of exposure. Dust from moisture-damaged schools in Spain and the Netherlands induced stronger immunotoxicological responses compared to samples from reference schools; the responses to Finnish samples were generally lower with no difference between the schools. In multivariate analysis, IL-6 and apoptosis responses were most strongly associated with moisture status of the school. The measured responses correlated with several microbial markers and numbers of particles, but the most important predictor of the immunotoxicological potential of settled dust was muramic acid concentration, a marker of Gram-positive bacteria.

BACKGROUND: The implementation, characteristics and utilisation of cardiac arrest teams (CATs) and medical emergency teams (METs) in Finland are unknown. We aimed to evaluate how guidelines on advanced in-hospital resuscitation have been translated to practice. METHODS: A cross-sectional postal survey including all public hospitals providing anaesthetic services. RESULTS: Of the 55 hospitals, 51 (93%) participated in the study. All hospitals with intensive care units (university and central hospitals, n = 24) took part. In total, 88% of these hospitals (21/24) and 30% (8/27) of the small hospitals had CATs. Most hospitals with CATs (24/29) recorded team activations. A structured debriefing after a resuscitation attempt was organised in only one hospital. The median incidence of in-hospital cardiac arrest in Finland was 1.48 (Q1 = 0.93, Q3 = 1.93) per 1000 hospital admissions. METs had been implemented in 31% (16/51) of the hospitals. A physician participated in MET activation automatically in half (8/16) of the teams. Operating theatres (13/16), emergency departments (10/16) and paediatric wards (7/16) were the most common sites excluded from the METs' operational areas. The activation thresholds for vital signs varied between hospitals. The lower upper activation threshold for respiratory rate was associated with a higher MET activation rate. The national median MET activation rate was 2.3 (1.5, 4.8) per 1000 hospital admissions and 1.5 (0.96, 4.0) per every cardiac arrest. CONCLUSIONS: Current guidelines emphasise the preventative actions on in-hospital cardiac arrest. Practices are changing accordingly but are still suboptimal especially in central and district hospitals. Unified guidelines on rapid response systems are required.

BACKGROUND: Patients discharged from the intensive care unit (ICU) are at increased risk for serious adverse events (SAEs). Recording vital functions and comprehending the consequences of altered vitals on general wards may be suboptimal. This potentially endangers recovery after successful intensive care. We aimed to determine the prevalence of vital dysfunctions after ICU discharge and their effect on patient outcome. METHODS: A prospective observational study. Adult patients discharged from a tertiary referral hospital ICU to general wards without treatment limitations were visited 24 h afterwards; their vitals were measured and reported to ward staff. Attending ward nurse responsible for patient was interviewed. RESULTS: The cohort consisted of 184 patients who had survived the first 24 h on the ward without complications (age: 57 ± 16 years; male: 68%). The prevalence of objectively measured vital dysfunctions was 15%, and the attending nurse had been unusually concerned about the patient in 19% of cases. Of the 184 patients, 9.8% subsequently suffered an SAE. In a multivariate logistic regression model, only vital dysfunctions (odds ratio 3.79; 95% confidence interval 1.18-12.2) and nurse concern (3.63; 1.17-11.3) were independently associated with an increased incidence of SAE. Medical emergency team (MET) assistance was never considered necessary by ward staff. Sensitivity of observed altered vitals on SAEs was 50% and specificity 89%. Sensitivity of nurse concern was 26%, specificity 84%. CONCLUSIONS: Simple vital function measurement and attending ward nurse's subjective assessment facilitate early detection of post-ICU patients at risk. The threshold in seeking assistance through MET remains high.

Elimination of the bacteriostatics tetracycline and doxycycline was compared in patients on long-term alcohol consumption to that in healthy controls. The half-life of doxycycline but not that of tetracycline was significantly shorter in alcoholics than in controls and in some patients the serum concentration of doxycycline decreased below the generally accepted minimum therapeutic concentration when dosed once daily. So, the dosing twice daily might be indicated especially if additional inducing drugs are used.
