POSTOPERATIVE DELIRIUM

This study tested whether exposure to natural light, instead of artificial light, could reduce delirium (sudden confusion) after heart surgery. Researchers observed 448 adults who had planned heart surgery and stayed in the ICU afterward. They compared patients in a unit with nat…

This study tested two different methods of pain control during back surgery to see which one works better. 29 adults having thoraco-lumbar fusion surgery received either a nerve block before surgery, numbing medicine injected at the end of surgery, or standard anesthesia alone. R…

This study tested whether giving a small amount of s-ketamine during chest surgery could prevent postoperative delirium (sudden confusion) in patients aged 60 and older. The trial involved 520 people having non-cardiac chest surgery. The goal was to see if s-ketamine works as wel…

This study tested a special anesthesia method during heart surgery in 70 older adults (age 60+). The goal was to see if it could lower the risk of confusion after surgery, keep blood pressure stable, and reduce pain and opioid use. The approach used brain monitoring to guide anes…

This study tested whether using an EEG brain-wave monitor during general anesthesia could reduce confusion and pain after dental surgery in children. 92 kids aged 4-10 were split into two groups: one got standard monitoring, the other got extra EEG guidance. The goal was to see i…

This study tested whether suvorexant, a sleep medication, could improve sleep and reduce delirium (sudden confusion) in older adults recovering from heart surgery in the intensive care unit. About 100 patients aged 60 and older received either suvorexant or a placebo for 7 nights…

This study tested two ways to manage pain after open-heart surgery: one using a single nerve block and another combining two blocks. 42 adults having heart surgery took part. The goal was to see if the combined block provides better pain relief and reduces complications like conf…

This study looked at whether a gentle electrical stimulation at specific acupoints (Neiguan and Shenmen) can help prevent delirium—sudden confusion—after abdominal surgery in patients aged 65 and older. The researchers also checked brain wave patterns to understand how it might w…

This study looked at over 2,400 adults who had surgery in Spanish hospitals to find out how often postoperative delirium (sudden confusion) happens within 48 hours after an operation. Researchers collected information before, during, and after surgery to identify which factors ma…

This study looked at whether two substances in the blood, zonulin and interleukin-8, are linked to confusion (delirium) after hip fracture surgery. Researchers measured these markers before and after surgery in 73 older adults. The goal was to see if these markers could help pred…

This study tested whether stimulating the phrenic nerve (which controls the diaphragm) during brain surgery could reduce postoperative problems like confusion (delirium) and lung issues. 120 adults having brain tumor surgery took part. The goal was to see if this simple intervent…
