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 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 compared two prescription numbing creams to see which better reduces pain during a common laser treatment for sun-damaged skin. Researchers tested each cream on a different half of the face in 22 participants before their laser procedure. The main goal was to measure w…

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 compared two different ways to place pain-relief catheters near nerves for patients having hand surgery. Researchers tested 140 patients to see if a newer technique provides better pain control 48 hours after surgery compared to the standard method. Both approaches use…

This study tested different ways to manage pain after laparoscopic gallbladder removal surgery. Researchers compared a specific nerve-blocking technique (TAP block) against standard local numbing injections in 160 patients. They found the TAP block provided better pain relief for…

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 specific numbing eye gel (Iheezo) acts as a barrier and stops an antiseptic (povidone-iodine) from killing germs before eye surgery. Researchers compared it to a different, thinner numbing drop (tetracaine) in 100 patients. They measured bacteria on the ey…
