POSTOPERATIVE DELIRIUM

This study tested whether stimulating the phrenic nerve (which controls the diaphragm) during brain surgery could lower the risk of postoperative problems like delirium and lung issues. 120 patients having brain tumor surgery took part. The approach is non-drug and aims to protec…

This study tested if being in a room with natural light instead of artificial light could prevent delirium (sudden confusion) after heart surgery. Researchers observed 448 adults in the ICU. The goal was to see if natural light lowers the chance of delirium and reduces the need f…

This study tested whether transcutaneous electrical acupoint stimulation (TEAS) — a mild electrical pulse on specific acupoints — could reduce postoperative delirium (confusion) in 226 elderly patients having abdominal surgery. Researchers also looked at brain wave (EEG) changes …

This study tested whether the sleep medication suvorexant (Belsomra) can help older adults sleep better and reduce delirium after heart surgery in the intensive care unit. One hundred patients aged 60 and older received either suvorexant or a placebo for seven nights after surger…

This study tested two ways to numb chest nerves after heart surgery: one block alone versus two blocks together. 42 adults having planned heart surgery through a breastbone incision took part. The goal was to see if adding a second block improved pain relief and reduced confusion…

This study tested whether giving a small amount of s-ketamine during chest surgery could reduce the risk of postoperative delirium (sudden confusion) in patients aged 60 and older. Over 500 participants were randomly assigned to receive either s-ketamine or another drug (dexmedet…

This study tested a brain-wave-guided anesthesia method combined with a planned pain management approach in 70 older adults (age 60+) having heart surgery. The goal was to see if it could lower the risk of confusion, keep blood pressure stable, and reduce pain and opioid use afte…

This study looked at 50 adults having heart bypass surgery to see if one sedative (dexmedetomidine) causes less confusion after surgery than another (midazolam). The goal was to find a way to reduce postoperative delirium, a common problem after heart surgery. Researchers checked…

This study tested two different methods of pain control during back surgery to see which one works better. 29 adults having 1-2 level lower back fusion surgery were randomly assigned to receive either a nerve block before surgery or a large dose of numbing medicine at the end. Th…

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 anesthesia care, the other got extra EEG guidance. The goal was t…

This study compared two common sedation drugs, propofol and dexmedetomidine, in 65 older adults undergoing a less invasive heart valve replacement called TAVR. The goal was to see which drug leads to better kidney function, less confusion, and fewer complications after the proced…

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 looked at how often patients develop confusion after surgery (postoperative delirium) and what factors increase the risk. Researchers tracked over 2,400 adults in Spanish hospitals who had surgery requiring an overnight stay. The goal is to use this information to crea…

This study followed 610 adults who had heart surgery to see how often they develop postoperative delirium—a sudden state of confusion that can come and go. Researchers collected information on known risk factors like age, high blood pressure, and diabetes, and tracked outcomes su…
