More anesthesiology trends
All specialties →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.
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.
EEG-guided anaesthesia
Processed EEG monitoring to guide anaesthetic depth.
Transversus abdominis plane block
Studies of the transversus abdominis plane (TAP) block for pain after abdominal surgery.

How these numbers are counted
PubMed query, searched in titles and abstracts by publication date:
"postoperative delirium"[tiab] OR "post-operative delirium"[tiab]Trials: ClinicalTrials.gov studies first submitted in each 12-month window that match the same terms. A query can miss synonyms or catch unrelated papers, so treat counts as approximate.
