ICU Delirium Is Associated with Cardiovascular Burden and Higher Mortality in Patients with Severe COVID-19 Pneumonia.

BACKGROUND: COVID-19 can lead to functional disorders and complications, e.g., pulmonary, thromboembolic, and neurological. The neuro-invasive potential of SARS-CoV-2 may result in acute brain malfunction, which manifests as delirium as a symptom. Delirium is a risk factor for death among patients hospitalized due to critical illness. Taking the above into consideration, the authors investigated risk factors for delirium in COVID-19 patients and its influence on outcomes. METHODS: A total of 335 patients hospitalized due to severe forms of COVID-19 were enrolled in the study. Data were collected from medical charts. RESULTS: Delirium occurred among 21.5% of patients. In the delirium group, mortality was significantly higher compared to non-delirium patients (59.7% vs. 28.5%; p < 0.001). Delirium increased the risk of death, with an OR of 3.71 (95% CI 2.16-6.89; p < 0.001). Age, chronic atrial fibrillation, elevated INR, urea, and procalcitonin, as well as decreased phosphates, appeared to be the independent risk factors for delirium occurrence. CONCLUSIONS: Delirium occurrence in patients with severe COVID-19 significantly increases the risk of death and is associated with a cardiovascular burden. Hypophosphatemia is a promising reversible factor to reduce mortality in this group of patients. However, larger studies are essential in this area.

Case Report of Cerebral Sinus Thrombosis Related to Immune Thrombotic Thrombocytopenia Following Administration of ChAdOx1 nCoV-19 for Vaccination against COVID-19.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) with cerebral venous sinus thrombosis (CVST) has been recently reported after vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We present a case of a patient with fulminant CVST and thrombocytopenia after receiving the ChAdOx1 nCoV-19 vaccine. Although the patient received immediate anticoagulant and intravenous immune globulin treatment, he died within 24 h after hospital admission. VITT and CVST are rare conditions; however, the course may be fatal. Therefore, clinicians should be familiarized with the clinical and laboratory features of VITT.

Early or late tracheotomy in patients after multiple organ trauma.

The analysis of the study group of 124 patients revealed a statistically significant shortening of mechanical ventilation requirement period in patients in whom tracheotomy had been performed before hospitalization day 10 (G1). The average length of mechanical ventilation was shorter by 20.3 days in G1 as compared to G2. On average, the duration of ICU stay was shorter by 39.4 days in G1 as compared to G2. Total hospitalization time was also significantly shorter in this group of patients (G1). The overall length of hospital stay for patients in whom tracheotomy had been performed prior to hospitalization day 10 was on average 43.1 days shorter as compared to patients in whom the procedure had been performed at a later date. Tab. I. provides the comparison of the results obtained in both study groups. Statistically significant differences (p < 0.05) were demonstrated between G1 and G2 regarding the length of the mechanical ventilation, the length of ICU stay, and length of hospitalization. null null No statistically significant differences were observed in mortality rates between the study groups (Fig. 1.) (P = 0.256). The mortality rate in early tracheotomy group (G1) was lower and amounted to 2%. In patients in whom tracheotomy was performed on day 10 or later (G2), the mortality rate was slightly higher and amounted to 9%. In some patients, initiation of treatment was required due to pneumonia developing as a complication in mechanically ventilated patients and referred to as ventilator-associated pneumonia. This complication developed in 6 patients in G1 and 26 patients in G2. The study assessed the relationship between the occurrence of this complication and the timing of tracheotomy. Pneumonia was significantly more frequent in patients in whom tracheotomy had been performed on hospitalization day 10 or later (P = 0.011). null null The comparison of results is presented in Tab. II.</br> </br>Another analyzed aspect of the study consisted in the results obtained by the patients in the baseline evaluation of the level of consciousness as assessed using the Glasgow Coma Scale (GCS). Data were checked for potential correlation between the GCS scores and the timing of the tracheotomy and the lengths of mechanical ventilation, ICU stay, and hospitalization. Correlation between GCS scores and the duration of stay within the ICU was demonstrated with a statistically significant correlation coefficient (Spearman's rank coefficient in the range of -0.4 to -0.2). </br> </br>ICU stay and total hospitalization lengths were shorter in patients with higher baseline GCS scores compared to patients with lower baseline GCS scores. The results are illustrated graphically (Fig. 2., 3.).

The following standards constitute the minimum requirements set by the SCMiB TCHP for good practice of the basic process of bariatric care throughout its entire period, which ensure satisfactory safety and effectiveness of the obesity treatment and its metabolic complications.

Etomidate, but not thiopental, decreases serum cortisol concentration in morbidly obese patients. A randomized controlled trial.

BACKGROUND: The effect of etomidate administration on the adrenal cortex in obese patients is still unclear. The objective of the study was to determine the influence of a single dose of etomidate on cortisol secretion in the morbidly obese. METHODS: 127 healthy patients were enrolled into the study. Data from 82 patients scheduled for elective laparoscopic surgery were analyzed. 62 of them were morbidly obese, while 20 had normal body mass. The participants were divided equally into etomidate and thiopental groups, depending on the kind of intravenous anaesthetic used for the induction of anaesthesia. Each patient's serum cortisol concentration was measured five times: on the day before surgery (sample A), two hours after the induction of anaesthesia (sample B), after a short tetracosactide test (sample C), 24 hours after the induction of anaesthesia (sample D), and after a second short stimulation test (sample E). RESULTS: The mean cortisol concentration in obese patients in the etomidate group was lower two hours after the induction of anaesthesia (sample B, P < 0.001), and 30 minutes after the first tetracosactide test (sample C, P < 0.001) compared to obese patients in the thiopental group. There were no differences between the groups in sample A (P = 0.833), D (P = 0.614) and E (P = 0.769). We found no changes in haemodynamic parameters between both groups. CONCLUSIONS: Etomidate decreased serum cortisol concentration and decreased reactivity to tetracosactide both in morbidly obese and in normal weight patients. This effect was reversible within 24 hours.

Thermal imaging evaluation of paravertebral block for mastectomy in high risk patient: case report.

Thoracic paravertebral block is the technique of injecting local anesthetic adjacent to the thoracic vertebra close to where the spinal nerves emerge from the intervertebral foramina. It is effective in treating acute and chronic pain of unilateral origin from the chest and abdomen. This technique causes pain relief with pulmonary function preservation and great hemodynamic stability. 66 year old woman (156 cm, 80 kg, BMI 32) with chronic right heart failure, hypertension and obesity, on chronic oxygen therapy was presented for elective mastectomy due to breast cancer. She suffered from severe COPD and also bullous emphysema. FVC 1.59 l; FEV1 0.55 l; FEV1%FVC 34.6. The paravertebral block was performed using the multi-shot percutaneous technique with additional light general anesthesia. For confirmation, of proper analgesia range, control of temperature changes, using FLIR i7 infrared camera, was performed. Control photos were made 20 min after the blockade and then 10 min later. Infrared photo showed rise of temperature reading in every marked region. There were no hemodynamic and pulmonary complications postoperatively. Paravertebral block in combination with sedation creates excellent conditions for breast surgery procedures. Additional temperature changes monitoring performed with infrared camera may confirm proper range of analgesia needed to perform surgery. Great cardiovascular stability and very good pulmonary function preservation make this method excellent for high risk patients. Low complication rate is additional advantage. In our opinion this method is recommendable.

The Influence of Bone Cement Implantation in Primary Hip Arthroplasty on S100B Protein Serum Concentration and Patients' Cognitive Functions as Markers of Brain Damage.

OBJECTIVE: The objective of the study was to evaluate the influence of the bone cement used during primary hip arthroplasty on brain functions assessed at the biochemical and clinical levels. The S100B protein is a biochemical marker of brain damage. Its plasma concentration was compared with the results of neuropsychological tests, conducted during the perioperative period. PATIENTS AND METHODS: Two groups of patients who underwent primary hip arthroplasty were analyzed; group one (n = 30) with the use of bone cement (cemented), group two (n = 30) without (cementless). All of the procedures were under spinal anesthesia with intravenous sedation. In each group, S100B protein concentration was examined before the surgery and just after the operation, and 6, 24, and 72 h after the procedure. Two neuropsychological tests were conducted before the surgery and 24 and 72 h after. The patients with preexisting blood flow disturbances inside the carotid and vertebral arteries and those with intraoperative mean arterial pressure below 50 mmHg were excluded from the study. STATISTICAL ANALYSIS: Data were analyzed using SPSS 15.0 for Windows (SPSS Inc., Chicago, IL, USA). The two groups were compared using the Mann-Whitney U-test. The comparison between the groups was done with Wilcoxon's signed ranks test. The correlations were analyzed using Spearman's rho test. RESULTS: There were no significant differences between the two groups in S100B protein concentration before the surgery. Just after the operation, the S100B protein concentration was elevated in both groups, but its level in the cemented group was significantly higher, particularly just after the surgery, and its normalization was slower than in the cementless group. The comparison of time points within each group revealed that there were no significant differences in patients' reaction time in the simple reaction test before and after the surgery (p = 0.056 and 0.163 in the cementless and 0.581 and 0.139 in the cemented groups), but a significantly longer mean reaction time in the choice reaction test was observed within each group after the surgery (p = 0.003 and 0.001 in the cementless and 0.001 and 0.014 in the cemented groups). There were no correlations between S100B protein plasma concentration and the results of the neuropsychological tests. CONCLUSIONS: There was a relationship between bone cement implantation during primary hip arthroplasty and elevated S100B protein plasma concentration during the short postoperative period, but the results of the neuropsychological tests did not reflect this.
