ANESTHESIA, LOCAL

This study tested if a simple, painless ultrasound scan of the eye could help predict which patients might get a specific type of headache after spinal anesthesia for knee replacement surgery. Researchers measured the optic nerve sheath in 176 patients before and after their proc…

This study compared two different ways to place a pain-numbing catheter for patients having outpatient hand surgery. Researchers tested whether a newer 'costoclavicular' approach provided better pain relief 48 hours after surgery than the standard 'paracoracoid' approach. The goa…

This study tested different ways to manage pain after laparoscopic gallbladder removal surgery. Researchers compared a nerve block technique against standard local anesthetic injections in 160 patients. They found the nerve block provided better pain relief with fewer complicatio…

This study aimed to find out which of two common numbing creams works better to reduce pain during a specific type of facial laser treatment for sun-damaged skin. Researchers tested the creams on opposite sides of participants' faces during their laser procedure. The main goal wa…

This study aimed to find the most effective method for managing pain after minimally invasive chest surgery. Researchers compared three different types of nerve blocks given before surgery to 155 adult patients. The goal was to determine which technique provided the best pain con…

This study tested whether a local anesthetic block, given through small tubes near the breastbone, could reduce the need for strong opioid painkillers after open-heart surgery. Researchers compared the anesthetic to a saltwater placebo in 340 patients. The main goal was to see if…

This study tested whether inhaling a pain-relief medication called Penthrox (methoxyflurane) could help men better tolerate minor scrotal or urologic procedures done with local anesthetic. Forty men were randomly assigned to receive either the standard local anesthetic alone or t…

This study tested whether adding a longer-lasting numbing medicine (ropivacaine) to the standard numbing shot (lidocaine) improves recovery after outpatient hand, wrist, or elbow surgery. Researchers compared the two methods in 91 patients to see which led to less pain and a bett…

This study checked if a new, thinner numbing gel for the eye blocks the germ-killing power of a standard antiseptic used before surgery. Researchers compared the new gel to a standard numbing drop in 100 patients to see which one allowed the antiseptic to work better. They measur…
