Tonsillectomy

This study compares two common substances—hydrogen peroxide and adrenaline—for controlling bleeding during tonsillectomy in children and teens aged 5 to 18. Surgeons apply one of the two to the surgical site and measure how quickly bleeding stops and how much blood is lost. The g…

This study looked at 250 people with Chiari malformation type I and syringomyelia to compare two surgical approaches: one that opens the covering of the brain and spinal cord, and another that also removes or shrinks the tonsils at the base of the brain. The goal was to see which…

Tonsillectomy causes significant pain in children. Researchers are testing whether injecting ropivacaine, a local anesthetic, around the tonsils during surgery reduces postoperative pain. The trial enrolls 60 children aged 3 to 6 who are having their tonsils removed. Doctors comp…

This trial investigates whether using EEG brain-wave monitoring to adjust sevoflurane anesthesia can reduce opioid use and improve recovery in children aged 2-8 years undergoing tonsillectomy. Half of the children receive standard anesthesia, while the other half have their anest…

This trial tests whether watching a 30-40 minute augmented-reality animation that shows a child's journey through surgery can reduce anxiety in children aged 3-12 before adenotonsillectomy. Half the children will watch the animation before surgery, while the other half receives s…

This trial investigates whether a drug called remimazolam can prevent emergence delirium—a state of confusion and agitation—in children aged 3 to 12 after tonsillectomy or similar procedures. Children are randomly assigned to receive either remimazolam or a placebo (salt water) b…

This study tested a special lollipop containing the painkiller diclofenac to help children aged 4 to 12 manage pain after having their tonsils removed. Fifty children received a weight-adjusted dose every 8 hours for the first day after surgery. The goal was to see if the lollipo…

This study tested whether having children gargle with a ketamine solution just before tonsillectomy surgery could reduce their pain afterward. 420 children aged 4 to 12 years participated, with half receiving the ketamine gargle and half a placebo (salt water). The researchers me…

This study tested whether letting children play with sand before a tonsillectomy could lower their anxiety and pain. Sixty-eight kids aged 7 to 10 were split into two groups: one did sand play, the other got standard care. Researchers measured anxiety before surgery and pain afte…
