ANESTHESIA, LOCAL

This study tested whether measuring the optic nerve sheath with ultrasound can predict postdural puncture headache (PDPH) after spinal anesthesia. 176 adults having knee replacement surgery were scanned before and after the procedure. The goal was to see if changes in nerve sheat…

This study compared two ways to control pain after minimally invasive heart bypass surgery: a newer erector spinae plane block (ESPB) versus the standard paravertebral block (PVB). 140 patients received one of the two blocks using the numbing drug ropivacaine. The goal was to see…

This study tested two different methods (paracoracoid vs. costoclavicular) for placing tiny catheters near nerves to deliver pain medicine after hand surgery. 140 adults having outpatient hand surgery took part. The goal was to see which approach provides better numbness and pain…

This study tested whether a nerve block placed near the breastbone after heart surgery can reduce the need for opioid painkillers. 340 adults having heart surgery through a standard chest incision were randomly assigned to receive either the numbing drug ropivacaine or a saltwate…

This study tested two different numbing creams to see which one works better for pain during a laser skin treatment. 22 adults with sun-damaged skin tried both creams on different sides of their face. The goal was to find which cream provides better pain relief and fewer side eff…

This study tested two local anesthesia methods for hand, wrist, or elbow surgery. One used lidocaine alone, the other added ropivacaine for longer pain relief. 91 adults participated. Researchers measured pain and recovery quality 48 hours after surgery to see if the combination …

This study tested whether breathing in a pain-relief medicine called Penthrox (methoxyflurane) can help reduce pain and anxiety during urologic procedures done with local anesthetic. Forty adult men having procedures like hydrocelectomy or testicular biopsy took part. The goal wa…

This study tested different ways to control pain after laparoscopic gallbladder removal in 160 adults. Patients received either a TAP block (an injection into the abdominal wall muscles), local anesthetic at the incision sites, both, or no extra pain relief. The TAP block group r…

This study tested three different nerve block techniques to control pain after thoracoscopic (chest) surgery. 155 adults were randomly assigned to receive either a serratus plane block, a paravertebral block, or both together, using the anesthetic ropivacaine. The goal was to fin…

This study looks at whether computer models can predict if local anesthetic (numbing) will work for people with a painful tooth condition called symptomatic irreversible pulpitis. Researchers analyzed records from 4,390 adult patients to compare three different machine learning a…

This study tested whether a numbing gel (chloroprocaine) used before eye procedures might block the germ-killing action of povidone-iodine, compared to standard numbing drops. Researchers took bacterial swabs from 100 adults before and after applying the medications. The goal was…
