Effect of Duration of Pre-Procedure Fasting on Clinical Outcomes in Intensive Care Patients Undergoing Percutaneous Tracheostomy - Article abstract #950128

The incidence of anemia and its association with postoperative complications in pediatric patients undergoing elective minor surgery are unknown. This study aims to determine the prevalence of anemia and its impact on postoperative complications in children undergoing elective minor surgery under general anesthesia. The preoperative complete blood count data of ASA I-II patients aged 1-18 years, for whom the pediatric surgery department planned an elective minor surgery under general anesthesia between January 1, 2019 and December 31, 2019, were evaluated retrospectively. The frequency of patients with abnormal hemoglobin values, the influence on preoperative treatment, the perioperative blood requirement and the complications were evaluated. Based on the specified inclusion interval, 851 of 3142 patients (784 Turks, 67 immigrants) met the inclusion criteria. It was observed that 24.38% of these patients had varying degrees of anemia (1.72% was rated as severe anemia). In addition, it was found that the operations of patients with anemia were not postponed and no additional assessment was required from the patients. It was found that the prevalence of anemia between Turkish patients and immigrant patients is similar. No complications were observed in the patients during the perioperative period. We found that the preoperative complete blood count test has limited value in patient management in children undergoing elective minor surgery and the prevalence of anemia in our area is quite high. Instead of routine laboratory tests, a careful medical history and physical examination are sufficient to determine the preoperative suitability of the pediatric patient before elective minor surgery.

Purpose: Families play a key role in the decision to donate the organs of people with brain death. However, studies on the factors affecting the decisions of families who are expected to make donation decision in a short time after their loss and possible emotional difficulties they experience afterwards are insufficient. In our study, we aimed to investigate the psychological experiences of donor families during and after the donation consent process and the factors affecting them. Methods: Relatives of donors who had brain death at least 6 months ago and gave their consent to be donors were included in the study. Demographic data form, Prolonged Grief Scale (PG-13), Grief and Meaning Reconstruction Inventory (GMRI), and Beck Depression Inventory (BDI) were administered to the participants. Results: In our study, it was found that male gender decreased the risk of depression (OR=0.08, p

Background: Contrast-enhanced imaging studies are widely used to diagnose and follow up acute cerebrovascular diseases. Exposure to contrast media may lead to nephropathy. This study investigated the incidence of contrast-induced acute kidney injury during intensive care follow-up of patients who underwent aneurysmal subarachnoid haemorrhage surgery and the impact of this condition on patient outcomes. Material and Methods: Patients >18 years of age with no known renal injury and admitted to the intensive care unit after Fisher Grade IV aneurysmal subarachnoid haemorrhage and surgery between January 2017 and June 2022 were retrospectively analysed. Renal injury was defined as a renal injury occurring within 48 hours of exposure to contrast media in line with the Kidney Disease Improving Global Outcomes criteria. Results: Among the 85 patients with subarachnoid haemorrhage who received at least one contrast medium, the mean age was 55, and 40% were female. 11.8% of the patients were found to have early acute kidney injury and were non-oliguric. At 48 hours, six, three, and one patients had Stage 1, 2, and 3 injuries, respectively. None of the patients required renal replacement therapy. Patients received a mean of 2 mL/kg/h saline infusion after contrast media administration and had a mean arterial pressure of 93.6 mmHg. There was no association between acute kidney injury and comorbidities, Glasgow coma scale, or APACHE II scores. Conclusions: The study found that the incidence of contrast-induced acute kidney injury was low and transient in patients followed at the ICU after aneurysmal subarachnoid haemorrhage (Fisher Grade IV) surgery. Adequate hydration and hemodynamic stability were found to be effective in reducing acute kidney injury in these patients.

Background: Although patient positioning in neurosurgical procedures is essential for optimal surgical exposure, it may adversely affect venous drainage, airway management, hemodynamic stability, and peripheral neurovascular structures. The aim of this study was to prospectively evaluate perioperative complications related to surgical positioning and head fixation methods in neurosurgical procedures. Material and Methods: This prospective, single-center observational study included 61 adult patients scheduled for neurosurgical procedures under general anesthesia. Patients were divided into two groups according to the occurrence of position-related perioperative complications. The primary outcome was the development of position-related perioperative complications, while secondary outcomes included hemodynamic changes and perioperative time variables. Results: During the perioperative period, a total of 12 position-related complications were identified in 10 patients (16.4%). The most frequently observed complications were bilateral orbital edema and diffuse facial edema. Anesthesia duration was significantly longer in the complication group compared with the uncomplicated group (p = 0.021). No significant differences were observed between the groups with respect to surgical duration, intraoperative fluid administration, or blood product transfusion. There was no statistically significant association between surgical position and the development of complications. Mean arterial pressure and heart rate values measured at different perioperative time points were comparable between the groups (all p>0.05). Position-related complications were most commonly observed in the prone position and predominantly involved the facial and upper airway soft tissues. Conclusion: Position-related perioperative complications occur at a non-negligible frequency in neurosurgical procedures. Appropriate patient positioning, standardized padding, and meticulous intraoperative management are of critical importance in ensuring patient safety.
