Randomized Controlled Trial Multicenter Study
ANGIOTENSIN II FOR CATECHOLAMINE-RESISTANT VASODILATORY SHOCK IN PATIENTS WITH ACUTE KIDNEY INJURY: A POST HOC ANALYSIS OF THE ATHOS-3 TRIAL.
Objective: The combination of catecholamine-resistant vasodilatory shock and acute kidney injury (AKI) is associated with high morbidity and mortality. The role of angiotensin II (ANGII) in this setting is unclear. Methods: We conducted a post hoc analysis of the Angiotensin II for the Treatment of High-Output Shock (ATHOS) 3 trial which assessed the effect of Intravenous ANG II or placebo in patients with refractory vasodilatory shock in 75 intensive care units across nine countries in North America, Australasia, and Europe. ⋯ Additionally, in this subgroup, compared with placebo, patients receiving ANGII were more likely to achieve a MAP response (P < 0.001) and had more days alive and free from RRT (P < 0.001). Conclusions: Compared with placebo, in patients with catecholamine-resistant vasodilatory shock and stage 3 AKI, ANGII is associated with lower 28-day, greater likelihood of MAP response, and more days alive and free from RRT. These findings support the conduct of future ANGII trials in patients with stage 3 AKI.

Randomized Controlled Trial
Examining the impact of permissibility hypercapnia on postoperative delirium among elderly patients undergoing thoracoscopic-laparoscopic esophagectomy: A single-center investigative study.
Objective: This study explores how permissive hypercapnia, a key aspect of lung-protective ventilation, impacts postoperative delirium in elderly patients following thoracic surgery. Methods: A single-center trial at The Second Hospital of Anhui Medical University involved 136 elderly patients undergoing thoracoscopic esophageal cancer resection. Randomly assigned to maintain PaCO 2 35-45 mm Hg (group N) or 46-55 mm Hg (group H). ⋯ Group H had lower pH and higher OI at T2-4 ( P < 0.05). CRP and CAR levels rose less in group H on the first day and 1 week later ( P < 0.05). Conclusions: Maintaining PaCO 2 at 46-55 mm Hg reduces POD incidence, possibly by enhancing rSO 2 levels and stabilizing intraoperative respiration/circulation.

Randomized Controlled Trial
Effects of Levosimendan on Diaphragmatic Dysfunction in Patients with Sepsis.
Objective: In this study, our aim was to examine the effects of levosimendan on diaphragmatic dysfunction in patients with sepsis, as well as assess its impact on respiratory muscle contractility and the outcome of weaning. Methods: This was a single-blind, randomized, controlled trial. Patients with diaphragmatic dysfunction and failure of spontaneous breathing trials (SBTs) were randomly and equally assigned to the experimental and control groups. ⋯ Furthermore, in terms of weaning outcomes, we did not find any statistically significant difference in the number of patients in the two groups who eventually underwent weaning ( P = 0.545). Conclusion: In this study, we found that levosimendan enhanced diaphragm contractile function. However, further investigations are required to explore its effect on weaning outcomes in patients undergoing mechanical ventilation.

Randomized Controlled Trial
Renal protective effect and clinical analysis of vitamin B6 in patients with sepsis.
Objective: To investigate the protective effect and possible mechanisms of vitamin B 6 against renal injury in patients with sepsis. Methods: A total of 128 patients with sepsis who met the entry criteria in multiple centers were randomly divided into experimental (intravenous vitamin B 6 therapy) and control (intravenous 0.9% sodium chloride therapy) groups based on usual care. Clinical data, the inflammatory response indicators interleukin 6 (IL-6), interleukin 8 (IL-8), tumor necrosis factor (TNF-α), and endothelin-1 (ET-1), the oxidative stress response indicators superoxide dismutase, glutathione and malondialdehyde, and renal function (assessed by blood urea nitrogen, serum creatinine, and renal resistance index monitored by ultrasound) were compared between the two groups. ⋯ There was no statistical difference between the two groups in the rate of renal replacement therapy and 28 d mortality ( P > 0.05). However, the intensive care unit length of stay and the total hospitalization expenses in the experimental group were significantly lower than those in the control group ( P < 0.05). Conclusion: The administration of vitamin B 6 in the treatment of patients with sepsis attenuates renal injury, and the mechanism may be related to pyridoxine decreasing the levels of inflammatory mediators and their regulation by redox stress.

Randomized Controlled Trial
Acetate Ringer's Solution versus Normal Saline Solution in Sepsis: A Randomized, Controlled Trial.
Background: Normal saline solution (NSS) and Ringer's acetate solution (RAS) are commonly given to critically ill patients as a fundamental fluid therapy. However, the effect of RAS and NSS on sepsis patient outcomes remains unknown. Methods: We conducted a single-center prospective open-label parallel controlled trial to enroll adult patients (>18 years old) diagnosed with sepsis. ⋯ The patients in the NSS-only group had a longer invasive mechanical ventilation days and a trend toward the accumulation of serum chloride. Conclusion: This study observed no statistically significant difference on MAKE28 and secondary outcomes among sepsis patients receiving RAS and NSS. However, it is unclear whether the large amount of fluid resuscitation before ICU admission and carrier NSS narrowed the difference between BSSs and NSSs.
