POSTOPERATIVE DELIRIUM (POD)

This study compared two sedative drugs—remimazolam and dexmedetomidine—to see which one better prevents postoperative delirium (sudden confusion) in patients aged 60 and older after thoracoscopic surgery. A total of 105 participants were randomly assigned to receive one of the tw…

This study tested whether using low tidal volume (gentle) ventilation during heart-lung bypass surgery can lower the risk of postoperative delirium—a state of confusion that can slow recovery. Researchers compared 130 patients who received either low tidal volume ventilation or n…

This study looked at whether giving a steroid called methylprednisolone during anesthesia can prevent postoperative delirium (sudden confusion) in elderly patients having abdominal surgery. Researchers analyzed records from 25,800 patients aged 65 and older. The goal was to see i…

This study tests whether ciprofol, a new sedative, can lower the risk of postoperative delirium (sudden confusion) in patients aged 65 and older after major chest surgery. About 214 participants will receive either ciprofol or the standard drug propofol during anesthesia. The goa…

This study looked at two types of ultrasound-guided nerve blocks for pain after hip replacement surgery in 62 patients aged 65 and older. One group got a PENG block plus a lateral femoral cutaneous nerve block, the other got a PENG block plus a lumbar erector spinae plane block. …

This study looked at 590 colorectal cancer patients to develop a risk tool that predicts postoperative delirium—a common complication causing confusion and slower recovery. Researchers combined blood test results (including the TyG index) with patient subtypes to create a scoring…

This completed study looked at whether a simple blood test measuring the ratio of two types of white blood cells (lymphocytes to monocytes) could help predict postoperative delirium—a state of confusion after surgery—in older adults. Researchers studied over 6,400 surgical patien…

This study looked at older adults (65+) having surgery to see if delirium (sudden confusion after surgery) makes frailty worse and how that affects their risk of dying within a year. Researchers followed over 6,000 patients, checking frailty before and one month after surgery, an…

This completed pilot study in the Czech Republic looked at whether simple memory and thinking tests given before hip replacement surgery can help predict who might develop postoperative delirium—a state of sudden confusion after an operation. Researchers tested 75 older adults us…
