Acute kidney injury in burns in the intensive care unit: A retrospective research.

BACKGROUND: Acute kidney injury (AKI) is one of the common complications, associated with high mortality and morbidity in patients with burn injuries. This study aimed to determine the frequency of AKI development, its affective factors, and mortality rates according to kidney disease improving global outcomes (KDIGO) criteria in the burn patients. METHODS: The study included patients who are hospitalized for at least 48 h and aged >18 years, whereas patients with a renal transplant, chronic renal failure, undergoing hemodialysis, <18 years of age, with a glomerular filtration rate of <15 on admission, and toxic epidermal necrolysis was excluded from the study. KDIGO criteria were used to evaluate the occurrence of AKI. Burn mech-anism, total body surface area, inhalation injury respiratory tract burn, fluid replacement at 72 h with Parkland Formula, mechanical ventilator support, inotrope/vasopressor support, intensive care unit, lenght of stay, mortality, abbreviated burn severity index (ABSI), acute physiology, and chronic health evaluation II (APACHE II) ve Sequential organ failure assessment (SOFA) were recorded. RESULTS: A total of 48 patients were included in our study, of which 26 (54.2%) developed AKI (+), whereas 22 (45.8%) did not (-). The mean total burn surface area was 47.30% in the AKI (+) group and 19.88% in the AKI (-) group. Mean scores of ABSI, II (APACHE II), and SOFA, the mechanical ventilation and inotrope/vasopressor support and the presence of sepsis were significantly higher in the AKI (+). No mortality was determined in the AKI (-) group, whereas 34.6% in the AKI (+) group which was significantly high. CONCLUSION: AKI was related to high morbidity and mortality in patients with burns. Using KDIGOs, classification in daily fol-low-up is useful in early diagnosis.

Transfusion-related acute lung injury and treatment with high-flow oxygen therapy in a pediatric patient: a case report.

Transfusion-Related Acute Lung Injury (TRALI) is an immune-inflammatory lung pathology that manifests within the first 6-72 hours after administration of blood products. However, due to reduced awareness of TRALI, it continues to be an underreported and often underdiagnosed complication of transfusion therapy. We report a case of a 6-year-old girl with myelodysplastic syndrome and TRALI developed in the first hour after platelet transfusion. Diagnosis of TRALI is based on the exclusion of etiologic factors such as volume overload and cardiogenic pulmonary edema following transfusion. Symptoms responded to high-flow oxygen therapy, so intubation was not attempted and full recovery was achieved.

Protective effects of dexmedetomidine and remote ischemic preconditioning on renal ischemia reperfusion injury in rats.

BACKGROUND: The aim of this study was to evaluate the effects of remote ischemic preconditioning (RIPC) and dexmedetomidine as pharmacological conditioning in a rat renal ischemia/reperfusion (IR) injury model. METHODS: Total of 28 male Wistar Albino rats weighing 250 to 300 g were divided into 4 equal groups. Group I (Sham; n=7): Laparotomy and renal pedicle dissection were performed, and the rats were observed under anesthesia without any intervention. Group II (IR; n=7): Following laparotomy and 45 minutes of left renal pedicle occlusion, 4 hours of reperfusion was performed. Group III (IR+D; n=7): Following laparotomy and ischemia, dexmedetomidine was administrated intraperitoneally (100 µg/kg) at fifth minute of reperfusion. Group IV (RIPC+IR; n=7): Under anesthesia, 3 cycles of ischemic preconditioning were applied to the left hind leg, and after 5 minutes, renal IR was performed. All rats were sacrificed after the left kidney was processed for conventional histomorphology. RESULTS: Total histomorphological renal injury score was significantly lower in the Sham group compared with the other groups (p<0.01). Total renal injury score of IR group was significantly higher than IR+D and RIPC+IR groups (p<0.01). There was no significant difference in the total renal injury score between the dexmedetomidine and RIPC groups (p=0.89). CONCLUSION: In the present study, it was demonstrated histomorphologically that both dexmedetomidine and RIPC decreased renal IR injury significantly. In addition, no significant difference was found between dexmedetomidine and RIPC groups.
