Background: Patients undergoing facial rejuvenation surgery are at unique risk of perioperative complications from the anesthetic utilized during the procedure. The ideal anesthetic agent is one that is safe to use in the outpatient population, has analgesic, sedative, and anesthetic properties, yet does not cause respiratory depression or hemodynamic irregularities.
Objectives: A retrospective analysis of a large outpatient facelift cohort was performed to determine if dexmedetomidine, an α 2-adrenergic receptor agonist, meets the criteria of an ideal adjunct for propofol in a total intravenous anesthesia protocol.
Methods: The charts of 791 patients who underwent rhytidectomy with total intravenous anesthesia were reviewed and data of patients' operative risk factors, perioperative management including medications administered, perioperative vital signs, and postoperative adverse events were recorded. Statistical univariate analyses were performed on the data.
Results: Dexmedetomidine resulted in a significant reduction and maintenance of blood pressure from onset of anesthesia until discharge from the postanesthetic recovery unit. The utilization of opioids and anxiolytics was significantly less than previously reported for other anesthetic types. The postoperative nausea/vomiting rate was 0.8% (6 patients). There were no postoperative admissions for inpatient management. Forty-three (5.3%) patients required a conversion to general endotracheal anesthesia and statistically significant risk factors include increased BMI, American Society of Anesthesiologists Class II or higher, preoperative hypertension, and multiple procedures performed.
Conclusions: This study demonstrated the safety and efficacy of dexmedetomidine in a large cohort of outpatients undergoing facelift. Dexmedetomidine meets the requirements for an ideal adjunct anesthetic within a total intravenous anesthesia protocol.

Although intraoperative magnesium sulphate administration has various advantages, its influence on the occurrence of postoperative acute kidney injury (AKI) remains unclear, particularly in patients undergoing robot-assisted radical prostatectomy (RARP). The steep Trendelenburg position and a high intra-abdominal pressure can render patients susceptible to AKI after surgery. This study aimed to evaluate the effects of intraoperative magnesium sulphate administration on postoperative AKI in patients who underwent RARP.

Background: Alzheimer's disease (AD) is a debilitating neurodegenerative disorder that is difficult to predict and is typically diagnosed only after symptoms manifest. Recently, CD4 T cell-derived double-negative T (DNT) cells have shown strong immuno-regulatory properties in both in vitro and in vivo neuronal inflammation studies. However, the effectiveness of DNT cells in treating on AD are not yet fully understood.

Background: Near-infrared fluorescence (NIF)-mapping with indocyanine green dye (ICG) facilitates the identification of the intersegmental plane during minimally invasive segmentectomy. Our pilot study showed that ICG is associated with an increase in oncological margin distance from the tumour, greater than the surgeon's best judgment. We hypothesized that, with greater experience, the surgeon's judgement will improve, and the benefit of ICG will diminish.
