RESUMO
INTRODUCTION: This study investigates the impact of sequential extracorporeal treatments with oXiris® or CytoSorb® plus Seraph-100® on the clinical and laboratory parameters of critically ill COVID-19 patients with bacterial superinfection. METHODS: Patients admitted to the intensive care unit with COVID-19, bacterial superinfection, and undergoing blood purification (BP) were enrolled in this prospective, single-center, observational study. "standard BP" with oXiris® or CytoSorb® were used in 35 COVID-19 patients with bacterial infection. Seraph-100® was added in 33 patients when available serially in the same oXiris® circuit or as sequential treatment with CytoSorb® as a sequential BP. RESULTS: A significant reduction in SOFA score 3 days after treatment was observed in patients undergoing sequential BP (11.3 vs. 8.17, p < 0.01) compared to those undergoing "standard BP" (11.0 vs. 10.3, p > 0.05). The difference between the observed and expected mortality rate based on APACHE IV was greater in the sequential BP group (42.4% vs. 81.7%, p < 0.001) than the "standard BP" (74.2% vs. 81.7%, p > 0.05). Patients treated with sequential BP had a longer survival than those treated with "standard BP" (22.4 vs. 18.7 months; p < 0.001). CONCLUSIONS: The sequential approach may enhance the positive effect of BP on organ dysfunction among critically ill patients with COVID-19 and bacterial superinfection.

OBJECTIVE: Despite widespread use of noninvasive ventilation (NIV) in some coronavirus disease 2019 (COVID-19) hypoxemic patients, its clinical application is still subject of debate. METHODS: This is a retrospective, observational study with data collected from 91 consecutive patients treated in COVID intensive care unit (ICU) in our institution between October 2020 and February 2021. Outcomes were represented as ventilation hours, ICU and hospital length of stay, and ICU and hospital mortality. RESULTS: Patients' mean age was 66 ± 11 y and severe COVID-19 pneumonia with mean paO2/FiO2 137 ± 57 was observed in 90% of the patients. High positive end-expiratory pressure (PEEP) NIV by means of total face mask was initially applied in 58 (64%) patients, high flow oxygen therapy (HFOT) in 25 (27%) patients, whilst invasive mechanical ventilation (IMV) started at the moment of admission in 8 (9%) patients. NIV and high flow oxygen therapy (HFOT) have been kept on throughout ICU stay in 50 (55%) patients, while 41 (45%) patients were put on IMV. Overall ICU mortality was 41%, while ICU mortality of patients on NIV was 14%. CONCLUSIONS: High PEEP NIV was convenient and safe as initial respiratory support and in some COVID-19 ARDS patients remained an optimal respiratory support throughout their disease.

Endotracheal intubation is the gold standard in inpatient treatment of cardiac arrest patients; however, there are conflicting research results in out-of-hospital conditions. This prospective study included 92 patients with confirmed cardiac arrest occurring outside a hospital facility, who fulfilled the inclusion criteria and whom the emergency ambulance team reached within 20 minutes from the event. Medical data on each patient (age, gender, cause of arrest, estimated time of arrest, time to arrival of the ambulance team, resuscitation commenced prior to arrival of the ambulance team, initial electrocardiographic rhythm, method of airway management, and success of resuscitation) were recorded. The airway maintenance techniques applied in the patients were endotracheal intubation and I-gel laryngeal mask (LMA). The rate of spontaneous circulation recovery resulting from different techniques of airway management and the incidence of spontaneous circulation recovery between the defibrillation rhythm and non-defibrillable rhythm groups were recorded for each patient. Forty-seven patients received endotracheal tube and the rest of 45 patients I-gel LMA treatment. The ratio of achieving spontaneous circulation with intubation versus I-gel LMA was 13 (28%) to 11 (24%) (p=0.725). The best return of spontaneous circulation results was recorded in patients suffering from ventricular fibrillation; however, there was no statistically significant difference between the intubation and I-gel LMA treatments (8 (47%) vs. 7 (41%); p=0.916). No statistically significant difference was observed between the outcomes of patients resuscitated by endotracheal intubation and I-gel LMA methods either.

We focused on the relationship of 0.5% tetracaine- and 0.4% oxybuprocaine-induced corneal anesthesia in rats, and pentadecapeptide BPC 157 (0.4 µg/eye), along with nitric oxide synthase (NOS) inhibitor N(gamma)-nitro-L-arginine methyl ester (L-NAME) (0.1 mg/eye) and/or NOS substrate L-arginine (2 mg/eye), applied in the form of eye drops. We assessed corneal sensitivity recovery (Cochet-Bonnet esthesiometer), corneal lesion elimination (staining with 10% fluorescein) and decrease in tear volume (Schirmer test). BPC 157 administration had a full counteracting effect. Recovery also occurred in the presence of NOS blockade and NOS substrate application. L-arginine eventually shortened duration of corneal insensitivity and exerted corneal lesion counteraction (and counteraction of tetracaine-induced decrease of tear volume) only in earlier but not in later period. L-NAME application led to longer duration of corneal insensitivity, increase in corneal lesions and decrease in tear volume. When L-NAME and L-arginine were applied together, they antagonized each other's effect. These distinctions may indicate particular NOS involvement (corneal insensitivity vs. corneal lesion along with tear production), distinctively affected by the administration of NO agents. However, additional BPC 157 co-administration would re-establish counteraction over topical ophthalmic anesthetic-induced effect, be it in its early or late course. We suggest BPC 157 as an antidote to topical ophthalmic anesthetics.

Head injuries are very common in children and are the most frequent cause of disability and death among children. This retrospective study included 350 children hospitalized for injury of neurocranium over a 5-year period at Dr Josip Bencevic General Hospital in Slavonski Brod. Boys were more commonly injured (63.4%) than girls. The most common injuries were recorded in children aged 7-14 (47.1%), followed by those aged 1-6 (33.8%) years. The injuries occurred slightly more often in urban (50.9%) than in rural (46.6%) setting. Children were more commonly injured in the street or on the road (38.6%), followed by injuries sustained at home (35.2%), at school (9.3%) and on playgrounds (5.7%). They were most commonly injured by fall (50%), followed by traffic injuries (33.5%). Statistically significant differences were found in the following age groups: all children younger than one year were injured by fall; children aged 1-14 were mostly injured by fall (less in traffic, and due to hitting), and those aged 15-18 mostly in traffic (less by fall and due to hitting). Children were mostly injured in the street or on the road (in traffic accidents), followed by injuries at home (mostly by fall), at school and around the house or in the yard (mostly by fall); on the playground (due to hitting) and on the road (in traffic accidents) (statistically significant difference). Most of them had head contusion and cerebral commotion combined (46.8%), followed by head contusion alone (12.5%) and skull fractures (10.5%). Hemorrhages and hematomas were rare (epidural, subdural, subarachnoid hemorrhage), found in 3.2% of cases. We hope that our results will prove helpful in planning preventive measures and treatment of injured children.

Acute respiratory failure due to chronic obstructive pulmonary disease (COPD) presents an increasing problem throughout the world. The aim of this study was to compare invasive and non-invasive mechanical ventilation (MV) for patients with COPD. A prospective, randomized trial was performed in a multidisciplinary intensive care unit for the period of 36 months and included 156 patients with COPD. MV procedure was performed using standard methods, and was applied as either invasive MV (IMV) or noninvasive MV (NIMV). Patients were randomized in two groups for application of MV using closed, nontransparent envelops. Comparison was made based on patient characteristics, objective parameters on admission and 1h, 4h, 24h, and 48h after admission and based on treatment outcome. We have confirmed that NIMV method is superior to IMV for patients with COPD. MV duration NIM:IMV was 94:172 hours, p < 0.001, time spent in Intensive Care Unit 120:223 hours, p < 0.001. Ventilator associated pneumonia 5(6%):29(37%), p < 0.001. The advantage of NIMV in COPD patients, especially in the early stages was confirmed.

Our aim was to evaluate the influence of static pulmonary compliance (Cst) on the choice of Mechanical Ventilation(MV) method and treatment outcome. A prospective, randomized trial conducted out at the multidisciplinary Intensive Care Unit (ICU) included 387 patients, randomized in two groups: noninvasive MV group and invasive MV group. Furthermore, each group was divided in two groups: Cst < or = 0.025 and Cst > 0.025 L/cm H2O. In patients with Cst > 0.025 L/cm H2O MV duration, noninvasive vs invasive, was 92 vs 114 h, p = 0.039, time spent in ICU 118 vs 164 h, p = 0.004. In patients with Cst < or = 0.025, MV duration was 141 vs 189 h, p < 0.001, time spent in ICU 190 vs 246 h, p = 0.001, all patients were intubated. Need for tracheostomy was 6 (11%) vs 39 (46%) patients, p = 0.005, and ICU mortality was 15 (26%) vs 21 (25%) patients. Statistical significance in favor of noninvasive method was confirmed in patients with Cst > 0.025 L/cm H2O in MV duration, time spent in ICU, need for tracheostomy and intubation rate. In the group with Cst < or = 0.025 no significant difference in treatment failure was recorded between the two MV methods.

AIM: To compare T-tube and pressure support ventilation (PSV) as two methods of mechanical ventilation weaning of patients with chronic obstructive pulmonary disease (COPD) after failed extubation. METHODS: A prospective randomized trial carried out at the multidisciplinary intensive care unit (ICU) over 2 years included 136 patients with COPD who required mechanical ventilation longer than 24 hours. The patients who could be weaned from mechanical ventilation were randomized to either a T-tube or PSV 2-hour spontaneous breathing trial. The patients in whom 2-hour trial was successful were extubated and excluded from further research. Patients in whom 2-hour trial failed had mechanical ventilation reinstated and underwent the same weaning procedure after 24 hours in case they fulfilled the weaning criteria. The weaning outcome was assessed according to the following parameters: extubation success, mechanical ventilation duration, time spent in ICU, reintubation rate, and mortality rate. RESULTS: Two-hour trial failed in 31 patients in T-tube and 32 patients in PSV group, of whom 17 and 23, respectively, were successfully extubated (P<0.001, chi(2)test). Mechanical ventilation lasted significantly longer in T-tube than in PSV group (187 hours vs 163 hours, respectively, P<0.001, Mann-Whitney test). Also, patients in T-tube group spent significantly more time in ICU than patients in PVS group (241 hours [interquartile range 211-268] vs 210 hours [211-268], respectively, P<0.001, Mann-Whitney test). Reintubation was required in 8 and 6 patients in T-tube and PVS group, respectively, and death occurred in 4 and 2 patients, respectively, during ICU stay. CONCLUSION: Patients with COPD who failed the 2-hour spontaneous breathing trial had more favorable outcome when PVS rather than T-tube method was used for weaning from mechanical ventilation.
