Objective: The aim of our study was to compare the clinical effects of sedation with dexmedetomidine vs. propofol in patients undergoing cardiac surgery and analyze their effects on the duration of mechanical ventilation (MV), length of stay in the intensive care unit (ICU), and total hospital stay.
Patients And Methods: The study included 120 patients who were randomized in a 1:1 ratio into two groups of 60 patients. The first group was sedated with continuous dexmedetomidine in doses 0.2-0.7 mcg/kg/h. The second group was sedated with propofol in doses 1-2 mg/kg/h.
Results: Patients sedated with dexmedetomidine required 2.2 hours less time on MV (p<0.001). There was a positive correlation between the duration of MV and the ICU length of stay (r=0.368; p<0.001), as well as between the duration of MV and the total hospital stay (r=0.204; p=0.025). Delirium occurred in the postoperative period in 25% of patients sedated with propofol, while in the dexmedetomidine group it was only 11.7% (p=0.059). Patients who developed delirium had a significantly longer duration of MV (12.6±5.4 vs. 9.3±2.5 hours, p=0.010).
Conclusions: Postoperative sedation with dexmedetomidine, compared to propofol, reduces the duration of MV, but does not influence the length of stay in the ICU and length of hospitalization after open heart surgery.

Background: Propofol is one of the most used intravenous anesthetic agents in traumatic brain injury (TBI) patients undergoing emergency neurosurgical procedures. Despite being efficacious, its administration is associated with dose-related adverse effects. The use of adjuvants along with propofol aids in limiting its consumption, thereby mitigating the side effects related to propofol usage.

Background: Our objective was to characterize the impact of common initial sedation practices on invasive mechanical ventilation (IMV) duration and in-hospital outcomes in patients with acute brain injury (ABI) and to elucidate variations in practices between high-income and middle-income countries.
Methods: This was a post hoc analysis of a prospective observational data registry of neurocritically ill patients requiring IMV. The setting included 73 intensive care units (ICUs) in 18 countries, with a total of 1,450 patients with ABI requiring IMV.

Cancer recurrence and metastasis remain critical challenges following surgical resection, influenced by complex perioperative mechanisms. This review explores how surgical stress triggers systemic changes, such as neuroendocrine responses, immune suppression, and inflammation, which promote the dissemination of residual cancer cells and circulating tumor cells. Key mechanisms, such as epithelial-mesenchymal transition and angiogenesis, further enhance metastasis, while hypoxia-inducible factors and inflammatory responses create a microenvironment conducive to tumor progression.

One intriguing binding partner of propofol is the kinesin motor domain, kif5A, a neuronal mitochondrial transport protein. Here, we used zebrafish WT and kif5Aa KO larval behavioral assays to assess anesthetic sensitivity and combined that with zebrafish primary neuronal cell culture to probe for alteration in mitochondrial motility.

Article Synopsis
- The study focused on the effectiveness of propofol versus dexmedetomidine in reducing emergence delirium (ED) in pediatric patients after anesthesia, finding a wide incidence range (2% to 80%).
- Eighty children aged 2-6 undergoing short surgeries were treated with either propofol or dexmedetomidine before surgery, with ED assessed using specific scales afterward.
- Results showed a significantly lower ED rate in the dexmedetomidine group (2.5% vs. 70%), along with reduced postoperative pain, indicating that dexmedetomidine is more effective than propofol for these patients.
