POSTOPERATIVE DELIRIUM (POD)

This study looked at two different ultrasound-guided nerve block techniques to manage pain after hip replacement surgery in people aged 65 and older. The goal was to see which method leads to better recovery quality, less pain, and fewer complications like confusion or nausea. Re…

This study tested whether using low tidal volume (gentle) ventilation during heart-lung bypass surgery could lower the risk of postoperative delirium (sudden confusion). 130 adults having planned heart surgery were randomly assigned to receive either gentle ventilation or no vent…

This study compared two sedative drugs, remimazolam and dexmedetomidine, to see which better prevents confusion (delirium) after chest surgery in patients aged 60 and older. Delirium is common after surgery and can slow recovery. The goal was to find a safer option with fewer sid…

This study looked at whether giving a steroid (methylprednisolone) during anesthesia can lower the chance of delirium—sudden confusion—in older adults after abdominal surgery. Researchers analyzed records from 25,800 patients aged 65 and older. The goal was to see if this approac…

This study looked at over 6,000 older adults having surgery to see if postoperative delirium (sudden confusion after surgery) makes frailty worse and raises the risk of death within a year. Researchers measured frailty before and one month after surgery, then checked survival at …

This study looked at whether a blood test measuring lymphocyte-to-monocyte ratio (LMR) can predict postoperative delirium (confusion) in older surgical patients. Researchers studied over 6,400 adults aged 65 and older who had elective noncardiac, nonneurosurgical procedures. They…

This study looked at 75 older adults having hip replacement surgery to see if simple memory and thinking tests could predict who might become confused after surgery (postoperative delirium). Participants took two short cognitive tests before their operation, and researchers check…
