Low T3 vs low T3T4 euthyroid sick syndrome in septic shock patients: A prospective observational cohort study.

BACKGROUND: Both phases of euthyroid sick syndrome (ESS) are associated with worse prognosis in septic shock patients. Although there are still no indications for supplementation therapy, there is no evidence that both phases (initial and prolonged) are adaptive or that only prolonged is maladaptive and requires supplementation. AIM: To analyze clinical, hemodynamic and laboratory differences in two groups of septic shock patients with ESS. METHODS: A total of 47 septic shock patients with ESS were divided according to values of their thyroid hormones into low T3 and low T3T4 groups. The analysis included demographic data, mortality scores, intensive care unit stay, mechanical ventilation length and 28-day survival and laboratory with hemodynamics. RESULTS: The Simplified Acute Physiology Score II score (P = 0.029), dobutamine (P = 0.003) and epinephrine requirement (P = 0.000) and the incidence of renal failure and multiple organ failure (MOF) (P = 0.000) were significantly higher for the low T3T4. Hypoalbuminemia (P = 0.047), neutrophilia (P = 0.038), lymphopenia (P = 0.013) and lactatemia (P = 0.013) were more pronounced on T2 for the low T3T4 group compared to the low T3 group. Diastolic blood pressure at T0 (P = 0.017) and T1 (P = 0.007), as well as mean arterial pressure at T0 (P = 0.037) and T2 (P = 0.033) was higher for the low T3 group. CONCLUSION: The low T3T4 population is associated with higher frequency of renal insufficiency and MOF, with worse laboratory and hemodynamic parameters. These findings suggest potentially maladaptive changes in the chronic phase of septic shock.

Triiodothyronine hormone supplementation therapy in septic shock patients with euthyroid sick syndrome: two pilot, placebo-controlled, randomized trials.

BACKGROUND: To assess 28-day survival in two pilot groups of septic shock patients with euthyroid sick syndrome (ESS) supplemented with triiodothyronine (T3). METHODS: A total of 95 septic shock patients with ESS were divided according to values of the thyroid hormones into low T3 and low T3T4 groups. Among 48 patients with low T3, 24 (50%) were randomized to T3 for 4 days and 24 (50%) to placebo. Among 47 patients with low T3T4, 24 (51%) were randomized to T3 for 4 days and 23 (49%) to placebo. The analysis included 28-day survival as the primary outcome and laboratory with hemodynamics as the secondary outcomes. Laboratory data were analyzed on the day of admission (T0), on the first (T1), third (T2) and seventh day (T3) with hemodynamics analyzed for the first four days. RESULTS: In the low T3 population, 18 (75%) patients receiving T3 died at day 28 compared with 8 (33.3%) patients receiving placebo (p = 0.004). In the low T3T4 population, 6 (25%) patients receiving T3 died in ICU compared with 12 (52.1%) patients receiving placebo (p = 0.039). Oral T3 treatment increased mean arterial pressure values at day 1, day 3 and day 7 in the low T3T4 population, (p = 0.015, =0.005 and =0.042 respectively), and had no significant effect on these values in the low T3 population. CONCLUSION: T3 supplementation was associated with a low 28-day mortality rate in patients with low T3T4 but with increased mortality in patients with low T3 ESS. These results suggest caution before initiating thyroid supplementation in septic patients. REGISTRATION: ClinTrials.gov (NCT05270798).

COVID-19 associated coagulopathy in septic critically ill patients - a retrospective cohort study.

Aim To determine the relationship between coagulation disorders and septic condition in COVID-19 critically ill patients. Methods Data from 99 patients who presented with COVID-19 acute hypoxemic respiratory failure (CAHRF) were divided into two groups: Group 1- patients who developed sepsis, and Group 2 - patients who developed septic shock. Age, sex, comorbidities, quick Sequential Organ Failure Assessment (qSOFA) score, vasopressor and inotrope requirement, laboratory findings (platelets, neutrophils, lymphocytes, procalcitonin - PCT, C-reactive protein, fibrinogen, D-dimer, sepsis-induced coagulopathy - SIC, and disseminated intravascular coagulation - DIC score) were recorded on the day of admission and on the day of starting invasive mechanical ventilation. The primary outcome was to establish COVID-19 associated coagulopathy with sepsis and septic shock; the secondary outcome measure was incidence of coagulopathy in septic COVID-19 critically ill patients. Results The most common coagulation abnormality was international normalized ratio (INR) (p=0.019) for Group 2, followed by the values of inflammatory parameters PCT (p=0.002) and lymphocytes (p=0.011) also for Group 2. The statistical significance of SIC score was observed for both groups (p=0.007) and p=0.012, respectively. Norepinephrine (p=0.000) and dobutamine (p=0.000) for Group 2, qSOFA for both groups (p = 0.000) were statistically significant. Conclusion The observed coagulation abnormalities met the criteria for a SIC diagnosis, therefore, the management of coagulation disorders at this stage of the disease should follow the management of a septic condition.

Ketamine as the main analgesic agent during analgesia-based sedation for elective colonoscopy - A randomised, double-blind, control study.

Aim: The aim of the study was to compare the analgesic effects of ketamine over fentanyl combined with propofol in analgesia-based elective colonoscopy with purpose of patient safety and satisfaction. Methods: This is a double-blinded prospective randomized controlled trial. Ninety patients were included and randomized to either fentanyl-propofol (Group FP, n: 30), ketamine-propofol (Group KP, n: 30) or propofol-control group (Group C, n: 30). Group FP patients received fentanyl and propofol, Group KP received ketamine and propofol and Group C, propofol. In all groups, incremental doses of propofol were used to maintain a Ramsay sedation score (RSS) of 5. Respiratory depression and hemodynamic parameters were monitored for the first minute and every 5 min during endoscopy. Fifteen minutes after the procedure, the degree of pain was assessed using a visual analog scale (VAS), the quality of recovery according to the Aldrete score (ARS), complications during and after the procedure and additional doses of propofol were recorded. Results: Mean arterial pressure (MAP) at 5 and 30 min (p < 0.05), heart rate (HR) at 15, 25 and 30 min (p < 0.05) and peripheral oxygen saturation (SpO2) at 30 min (p < 0.05) were statistically significant for Group FP. Desaturation (*p = 0.033), and weakness (*p = 0.004) was also significant for Group FP at 20, 25 and 30 min (p < 0.05). Pain was lower assessed for the Group KP according to the VAS (**p = 0.025). Conclusion: In analgesia-based colonoscopy, ketamine provides appropriate analgesia and less incidence of complications compared to fentanyl.

A comparison of different doses of fentanyl for patients undergoing elective colonoscopy: a randomized double-blind clinical trial.

Aim To investigate analgesic and side effects of different doses of fentanyl in combination with propofol for colonoscopy. Methods This prospective randomized double-blind study conducted between 2019 and 2020 included 64 patients. Patients were randomized: Group 1 (fentanyl 0.5 µg/kg) and Group 2 (fentanyl 1.0 µg/kg) both in combination with propofol. Ramsay sedation score (RSS) was obtained at 5 with an additional dose of propofol. The primary outcome was the patient's postprocedural pain and adverse events during and after the procedure. Results The RSS means were statistically lower for Group 2 at the beginning and every 5 minutes of the procedure. Mean arterial pressure (MAP) for Group 2 (first, 5, 25 and 30 min) was significantly lower (p=0.000, and heart rate (HR) was significantly higher for Group 1 (during the entire procedure) (p=0.000) than in another group; peripheral oxygen saturation (SpO2 ) was significantly lower for measurements within both groups (Group 1, 5, 10, 15 min; Group 2, 5, 10,15 min) (p=0.000 and p=0.000, respectively). Anxiety (p=0.010), weakness (p=0.000) and confusion (p=0.023) proved to be significantly higher for Group 1, and hypotension (p=0.001) for Group 2 than in another group. No statistical significance of Visual Analogue Pain Scale (VAS) (p=0.501) and Aldrete recovery score (ARS) (p=0.845) was found. Conclusion There was no significance in postprocedural abdominal pain between the group of patients administered fentanyl at a dose of 0.5 µg/kg and the group of patients administered fentanyl at a dose of 1.0 µg/kg; however, prevalence of complications was more significant in the group with a fentanyl at a dose of 0.5 µg/kg.

Hemorrhage after adenotonsillectomy in children: tertiary center experiences.

BACKGROUND: Adenotonsillectomy is the most commonly performed surgery in the pediatric population. Hemorrhage after adenotonsillectomy, which can occur at any time postoperatively, is one of the most serious complications. OBJECTIVE: To determine the frequency of hemorrhage in children after adenotonsillectomy and to compare postoperative hemorrhage with regard to age and sex. METHODS: A cross-sectional longitudinal study was conducted at the Ear, Nose, and Throat Clinic, University Clinical Center Tuzla, and included all children of both sexes, aged 3 to 15 years, who underwent adenotonsillectomy during a 1.5-year period. RESULTS: A total of 201 children aged 3-15 years underwent adenotonsillectomy, 113 males and 88 females, which corresponds to a ratio of 1.28: 1. Adenotonsillectomy was performed in 147 (73.1%) patients and adenoidectomy in 54 (27%). In the overall sample, there were 19 (9.5%) subjects with postoperative hemorrhage. Primary hemorrhage occurred in 9 subjects (47%) and secondary hemorrhage in 10 subjects (53%). Significantly more female subjects had postoperative hemorrhage. In the group of subjects with hemorrhage, the mean age (standard deviation) was 8.45 (3.3) years. Tonsillar lodges are common sites of hemorrhage. CONCLUSION: The frequency and causes of hemorrhage after adenotonsillectomy in our study are partially comparable to the world data.

Adenoma Detection Rate in Colonoscopic Screening with Ketamine-based Sedation: A Prospective Observational Study.

Objective: This study aimed to determine the relationship between one of the most commonly used anesthesia techniques, ketamine-based sedation, on the value of adenoma detection rate (ADR) during colonoscopy screening. Methods: This prospective, observational study included 140 patients, who underwent a standard colonoscopy preparation before the procedure. Sedation regimens included ketamine at 0.5 mg/kg and propofol at 0.5 mg/kg. Additional doses of propofol were administered at 0.5 mg/kg to maintain the Ramsey Sedation scale. Baseline characteristics, ADR, bowel preparation quality according to the Chicago bowel preparation (CHBP) scale, cecal intubation, colonoscopy removal, and complications were analyzed. Results: The mean age of patients was 55.76 years; 40 (28.6%) were males and 100 (71.4%) were females. The ADR was 43.57%, wherein 15.71% in males and 27.86% in females. There were 43.6% adenomas, 17.9% biopsies, and 22.9% polypectomies. The largest location of adenomas/polyps were in the rectum and sigmoid and ascending colon (p=0.11), a biopsy of the sigmoid colon and ileum (p<0.05), polypectomy of the rectum and sigmoid and ascending colon (p<0.05). The cecal intubation was 93.6% with a withdrawal time that is >6 min in most patients (80%) (p<0.05). The CHBP scale showed good bowel preparation (p<0.05) without complications. Conclusions: Ketamine-based sedation is in good overall correlation with ADR. Therefore, the sedation technique should be included for ADR assessment in the future.

Clinical characteristics, comorbidities and mortality in critically ill mechanically ventilated patients with Covid-19: a retrospective observational study.

Aim To analyse demographic data, clinical symptoms and signs, laboratory data and comorbidities in patients with COVID-19 pneumonia admitted to the intensive care unit (ICU), mechanically ventilated with fatal outcome. Methods Medical records of 92 patients were retrospectively analysed. Demographic data, clinical symptoms and comorbidities were collected on the day of hospital admission. Clinical signs and laboratory data were collected on the day of hospital admission (T1), on the day of starting non-invasive ventilation (T2), and on the day of starting invasive ventilation (T3). Results Average age of the patients was 60.05 years. Patients over 50 years of age, 71 (77.1%) (p=0.000), and males, 62 (67.4%; p=0.001) were predominant. The most common patient symptoms were exhaustion, myalgia, dyspnoea and cough. Hyperthermia was recorded on the day of hospital admission. Tachycardia, hyperglycaemia, hypoxemia were recorded at all observed study times. The most common comorbidity was hypertension arterialis with a very strong correlation with fatal outcome, followed by diabetes mellitus and chronic heart disease that were moderately correlated with fatal outcome. Conclusion The treatment of COVID-19 patients in ICU with mechanical ventilation has a high failure rate. Demographic data, clinical symptoms and signs as well as accompanying comorbidities can be a significant component in making decisions about diagnostic-therapeutic procedures.

Predictive factors for noninvasive mechanical ventilation failure among COVID-19 critically ill patients - a retrospective cohort study.

Aim To identify predictive factors related with noninvasive ventilation (NIV) failure that are not based on the patient's respiratory status or acid base gas analyses in COVID-19 critically ill patients, and to create a predictive model of NIV failure. Methods A total of 73 COVID-19 critically ill patients who developed acute respiratory failure and underwent NIV were divided into two groups: Group 1, patients who required endotracheal intubation and invasive mechanical ventilation after NIV and Group 2, patients with successful weaning from NIV. Demographic data, clinical symptoms and signs, clinical index and scores, duration indicators and laboratory data were analysed. Predictive factors of NIV failure were assessed using univariate and multivariate regression analyses followed by the receiver operating characteristic (ROC) curve. Results In the Group 1 (NIV failure) there were 54 (73.97%) patients. Predictive factors for NIV failure were: the presence of dyspnoea on the day of admission at hospital (p<0.05; sensitivity 44.40%; specificity 84.20%), higher radiographic assessment of lung oedema score (RALES) on the day of starting NIV (p<0.009; sensitivity 70.40%; specificity 73.75%), higher length of NIV (p<0.014; sensitivity 48%; specificity 84.10%) and higher urea on the day of starting NIV (p<0.004; sensitivity 70.44%; specificity 73.72%) Conclusion NIV treatment in COVID-19 critically ill patients has a high failure rate. In addition to respiratory parameters, dyspnoea, higher RALES, higher length of NIV and increased urea value could predict NIV failure. These factors should be considered in treatment decision making.

PATIENT CLINICAL CONDITION IN RELATION TO HYPOXEMIA AND CHEST X-RAY CHANGES IN NOVEL CoV-19 PNEUMONIA: A CASE REPORT.

Persistent changes on chest x-ray and hypoxemia in arterial blood gas analyses have been described in several cases in novel CoV-19 virus (nCoV-19) patients. These changes are usually not expressed to a large extent. Our goal was not only to present a patient with comorbidities in whom residual pulmonary infiltrates remained with consequent hypoxemia after extubation, but also to show that these changes do not always correlate with the clinical condition. In summary, despite chest x-ray changes and hypoxemia, with appropriate respiratory physiotherapy, the patient had a satisfactory clinical status.
