Cisplatin is one of the most widely used chemotherapeutic agents in oncology, although its nephrotoxicity limits application and dosage. We present the results of a clinical study on prophylaxis of cisplatin-induced nephrotoxicity in patients with peritoneal carcinomatosis undergoing cytoreduction and hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC-cisplatin). Prophylaxis was with imipenem/cilastatin. Cilastatin is a selective inhibitor of renal dehydropeptidase I in the proximal renal tubule cells that can reduce the nephrotoxicity of cisplatin. Unfortunately, cilastatin is not currently marketed alone, and can only be administered in combination with imipenem. The study has a retrospective part that serves as a control (n = 99 patients receiving standard surgical prophylaxis) and a prospective part with imipenem/cilastatin prophylaxis corresponding to the study group (n = 85 patients). In both groups, we collected specific data on preoperative risk factors of renal damage, fluid management, hemodynamic control, and urine volume during surgery (including the hyperthermic chemotherapy perfusion), as well as data on hemodynamic and renal function during the first seven days after surgery. The main finding of the study is that cilastatin may exert a nephroprotective effect in patients with peritoneal carcinomatosis undergoing cytoreduction and hyperthermic intraperitoneal cisplatin perfusion. Creatinine values remained lower than in the control group (ANOVA test, p = 0.037). This translates into easier management of these patients in the postoperative period, with significantly shorter intensive care unit (ICU) and hospital stay.

Endotoxin, a component of the cell membrane of gram-negative bacteria, is a trigger for dysregulated inflammatory response in sepsis. Extracorporeal purification of endotoxin, through adsorption with polymyxin B, has been studied as a therapeutic option for sepsis. Previous studies suggest that it could be effective in patients with high endotoxin levels or patients with septic shock of moderate severity. Here, we perform a retrospective, single-centre cohort study of 93 patients suffering from abdominal septic shock treated with polymyxin-B hemoperfusion (PMX-HP) between 2015 and 2020. We compared deceased and surviving patients one month after the intervention using X2 and Mann-Whitney U tests. We assessed the data before and after PMX-HP with a Wilcoxon single-rank test and a multivariate logistic regression analysis. There was a significant reduction of SOFA score in the survivors. The expected mortality using APACHE-II was 59.62%, whereas in our sample, the rate was 40.9%. We found significant differences between expected mortality and real mortality only for the group of patients with an SOFA score between 8 and 13. In conclusion, in patients with abdominal septic shock, the addition of PMX-HP to the standard therapy resulted in lower mortality than expected in the subgroup of patients with intermediate severity of illness.

Introduction Compared with the operating room, tracheal intubations in the intensive care unit (ICU) are associated with worsened glottic view, decreased first-time success rate and increase in the technical difficulty of intubation and incidence of complications. Videolaryngoscopes (VLs) have been proposed to improve airway management, and while recent studies have confirmed that VLs improve intubation conditions in this patient population, there remains a lack of clarity regarding the selection between a standard Macintosh blade or a hyperangulated one, to determine which yields the best outcomes. The purpose of this study was to compare successful intubation on the first attempt with the Macintosh VL versus the hyperangulated VL during tracheal intubation in ICU patients. We hypothesise that tracheal intubation using the hyperangulated VL will improve the frequency of successful intubation on the first attempt. Methods and analysis The INtubation VIdeolaryngoscopy BLADE-ICU trial is a prospective, multicentre, open-label, interventional, randomised, controlled superiority study conducted in 29 ICUs in Spain. Patients will be randomly assigned in a 1:1 ratio to undergo intubation using a Macintosh VL (control group) or a hyperangulated VL (experimental group) for the first intubation attempt. The primary outcome is successful intubation on the first attempt. The secondary outcomes include the time to intubation, attempts for successful intubation, laryngoscopic vision assessed with the modified Cormack-Lehane scale, the need for adjuvant airway devices for intubation, difficulty assessed by the anaesthesiologist and complications during tracheal intubation. Enrolment began on 1 May 2024 and is expected to be completed in 2025. Ethics and dissemination The study protocol was approved on 29 February 2024, by the Ethics Committee of Galicia (CEImG, code No. 2024-031). The results will be submitted for publication in a peer-reviewed journal. Trial registration number NCT06322719.

Patients with severe traumatic brain injury (STBI) often experience an abnormal hemostasis that contributes to mortality and unfavorable neurological outcomes. Objectives: We aimed to analyze epidemiologic, clinical, and laboratory factors associated with mortality in patients with STBI during the first 48 h after in-hospital admission. Methods: We performed an observational retrospective study of STBI patients with associated extracranial trauma [defined as Injury Severity Score (ISS) ≥ 16 with an Abbreviated Injury Scale (AIS) head and neck ≥ 3 and Glasgow Coma Scale (GCS) ≤ 8] admitted to a Level II trauma center over seven years (2015–2021). Patients were divided into two groups: survivors and dead. We assessed differences regarding demographics, trauma severity, hemodynamics, disability, need for surgery, length of stay, transfusions, need for massive transfusion protocol, and hemostatic laboratory parameters at different time points. Results: A total of 134 STBI patients were included. Patients who died were older, mostly men, and showed higher trauma severity and disability. Hemoglobin, platelets, and clotting parameters deteriorated after admission to the emergency department (ED) with significant differences between groups within the first 24 h after admission. Platelet count < 150 × 103/μL at ED arrival, GCS, and age were independent risk factors for mortality. Conclusions: Older age, GCS, and platelet count at ED arrival were independent risk factors for mortality in STBI patients with associated extracranial trauma. Early thrombocytopenia < 150 × 103/μL at ED arrival may be used as a simple prognostic tool to early predict mortality between non-isolated STBI.

Spinal cord infarction is an uncommon phenomenon, which can be caused by different etiologies, constituting a real diagnostic challenge which can lead to devastating consequences. General anesthesia in beach chair positioning with intraoperative hypotension in order to avoid surgical bleeding are associated with hypoperfusion and potential neurological ischemia-related complications. We present a case of spinal cord ischemia in the context of shoulder surgery in a beach chair position.
