Purpose: Postoperative pain is an acute pain that begins with surgical trauma and decreases as the tissue heals. The transversus abdominis plane (TAP) block is one of the abdominal field blocks used in the treatment of acute postoperative pain after lower abdominal surgery. This study aims to investigate the effects of dexamethasone added to a local anesthetic solution on postoperative analgesia in ultrasonography-guided TAP block.

Aim/objective: This study investigated demographic characteristics, hemodynamic values, respiratory datas, laboratory values ​​such as biochemistry and blood gas, and treatment approaches of coronavirus disease 2019 (COVID-19)-related and non-COVID-19-related acute respiratory distress syndrome (ARDS) patients hospitalized in the intensive care unit (ICU).

Background: Determining the differences and similarities between COVID-19-related ARDS (CARDS) patients and non-COVID-19-related ARDS (NCARDS) patients will be useful to better understand these two diseases.

Materials And Methods: A total of 32 NCARDS patients who were followed and treated in the ICU for various reasons between January 2015 and December 2020 and 32 CARDS patients who were followed and treated in the ICU for various reasons between March 2020 and December 2020 were examined retrospectively.

Traumatic brain injury (TBI) is a significant health problem with a high mortality rate. Inflammatory markers can predict the prognosis of TBI where neuroinflammation is essential. In this study, the prognostic value of the systemic immune-inflammation index (SII), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) at admission in patients with critical TBI was investigated.

Objective: The incidence of postoperative morbidity and mortality in hip fracture patients is high and is associated with nutritional deficiencies. This study investigated the predictive value of preoperative prognostic nutritional index (PNI) on postoperative intensive care unit (ICU) requirement and mortality in geriatric hip fracture patients.

Methods: Geriatric (≥65 years old) hip fracture patients who underwent surgery between January 2021 and September 2023 were evaluated retrospectively.

Background And Objectives: Candidemia is the most common serious fungal infection in critically ill patients in intensive care units (ICU). It series fourth among bloodstream infectious agents. In this study, candidemia risk analysis was examined in COVID 19 and non-COVID 19 patients during the pandemic period.

Objective: Early and accurate diagnosis of brain death in intensive care units (ICU) is essential for organ transplantation. This study aimed to evaluate the cases diagnosed with brain death in the ICU of a tertiary center in Istanbul.

Methods: The cases diagnosed as brain death in the ICU during the ten years between January 2013 and September 2022 were evaluated retrospectively.

Background: This study investigates the potential of ChatGPT-4, developed by OpenAI, in enhancing medical decision-making processes, particularly in preoperative assessments using the American Society of Anesthesiologists (ASA) scoring system. The ASA score, a critical tool in evaluating patients' health status and anesthesia risks before surgery, categorizes patients from I to VI based on their overall health and risk factors. Despite its widespread use, determining accurate ASA scores remains a subjective process that may benefit from AI-supported assessments.

Objective: This retrospective observational study aimed to investigate the effect of different doses of sugammadex used in reversing neuromuscular blockade in electroconvulsive therapy (ECT) procedures on patient recovery and hemodynamic measurements.

Methods: Anesthesia induction was performed using propofol (1 mg/kg) and rocuronium (0.4 mg/kg).

Introduction: Caudal block (CB) and erector spina plane block (ESPB) have been shown to provide effective postoperative analgesia following circumcision. Our aim was to compare the analgesic efficacy of sacral ESPB and CB, as well as the time to first analgesic requirement and postoperative complications.

Methods: Patients aged 1-7 years in the ASA I-II group, who were scheduled for circumcision, were included in the study.

Background: Patients operated under emergency conditions have a higher risk of death and complications than those per-formed under elective conditions. Especially the patient group with high comorbidity needs to be evaluated more specifically. Accord-ing to the surgical risk and American Society of Anesthesiologists (ASA) scoring, the perioperative risk should be determined quickly, and the relatives of the patients should be informed.

Introduction In this study, we planned to investigate the effect of hyperoxygenation on mortality and morbidity in patients with head trauma who were followed and treated in the intensive care unit (ICU). Methods Head trauma cases (n = 119) that were followed in the mixed ICU of a 50-bed tertiary care center in Istanbul between January 2018 and December 2019 were retrospectively analyzed for the negative effects of hyperoxia. Age, gender, height/weight, additional diseases, medications used, ICU indication, Glasgow Coma Scale score recorded during ICU follow-up, Acute Physiology and Chronic Health Evaluation (APACHE) II score, length of hospital/ICU stay, the presence of complications, number of reoperations, length of intubation, and the patient's discharge or death status were evaluated.

Article Synopsis
  • - The study aimed to explore how serum levels of Vitamin A and Vitamin C relate to the severity of COVID-19 in hospitalized patients, using blood samples and CT imaging for assessment.
  • - Results showed that COVID-19 patients had significantly lower levels of both vitamins compared to healthy controls, indicating a potential nutritional deficiency in these patients.
  • - There were notable negative correlations between the levels of Vitamin A and C and both the extent of lung involvement (CT severity score) and the duration of hospitalization, suggesting that lower vitamin levels may predict worse outcomes.

Background: Although obstetric morbidity and mortality have decreased recently, rates are still high enough to constitute a significant health problem. With the COVID-19 pandemic, many obstetric patients have required treatment in intensive care units (ICU).

Objectives: Evaluate critical obstetric patients who were treated in an ICU for COVID-19 and followed up for 90 days.

Introduction: Quantitative thorax Computed Tomography (CT) is used to determine the severity of COVID-19 pneumonia. With a new approach, quantitative thoracic CT is to contribute to the triage of patients with severe COVID-19 pneumonia in the ICU and to evaluate its relation with mortality by taking into account the vaccination status.

Methods: Fifty-six patients who had a diagnosis of COVID-19 pneumonia confirmed in the adult ICU were evaluated retrospectively.
