What anesthesiology is researching now
The topics gaining the most ground, ranked by the PubDaily Trend Score: new research, stronger evidence, new trials and new guidelines. 291 topics in 22 specialties, updated 18 Oct 2026.
Monthly reportThe fastest-rising topics in medicine: October 2026Read →Opioid-free anaesthesia
Anaesthesia techniques that avoid or minimise intraoperative opioids.
GLP-1 drugs and perioperative aspiration
Delayed gastric emptying with GLP-1 based medicines and the risk at anaesthesia.
Key point: GLP-1 RA-based therapies should continue in most patients, with individualized risk assessment and gastric ultrasound when delayed gastric emptying is suspected.
Liposomal bupivacaine
Studies of liposomal bupivacaine for postoperative analgesia and regional blocks.
Intraoperative hypotension
Low blood pressure during surgery and its effects on outcomes.
Key point: In adults undergoing elective noncardiac surgery, targeting higher intraoperative blood pressure values does not improve major postoperative outcomes compared with routine management.
Postoperative delirium
Acute confusion after surgery, its prevention and outcomes.
Fascial plane blocks
Regional blocks such as the erector spinae plane and quadratus lumborum blocks.
Key point: For adults, fascial plane blocks are strongly recommended to reduce pain and/or opioid requirements after open cardiothoracic, abdominal, retroperitoneal, pelvic surgeries and mastectomy.

How the Trend Score works
Four signals
Growth in new papers (35%), growth in randomised trials, meta-analyses and systematic reviews (25%), new clinical trials registered (20%), and new guidelines and consensus statements (20%), each over the last 12 months against the 12 before.
A score out of 100
Each signal is ranked against every topic we follow, so a score of 90 means the topic is ahead of about 90% of them. Rising fast: 80 and above. Rising: 55 to 79. Emerging: fewer than 100 papers the year before, too few to rank.
What it does not tell you
