Dear All,

As the President of the Royal College of Anesthesiologists of Thailand (RCAT), it is my great pleasure to graciously welcome you to our 23rd ASEAN Congress of Anesthesiologists (ACA2023). The ACA was established by the collaboration and cooperation of its members across ASEAN countries. The mission is to provide a forum for the anesthesiologists to have excellent opportunities to exchange their mutual interests and experiences and share current advanced knowledge in anesthesia, critical care and pain medicine.

Since its inception, the ACA has held its scientific meeting regularly every two years. The meeting venue has been voluntarily rotated among the member countries. However, the effect of the global pandemic of the COVID-19 era has precluded only our on-site meetings, but our relationships remain. The situation is improving, and Thailand has the great opportunity to return our relationships by hosting this ACA2023.

I would like to take this opportunity to humbly invite all of you to join this resuming scientific congress. I do hope our hosting of the ACA2023 will be a fruitful and appropriate platform for communication academically and socially among our members to share their valued and distinctive experiences.

Best wishes and kind regards,


Ruenreong Leelanukrom

Professor in Anesthesiology

President, the Royal College of Anesthesiologists of Thailand

This upcoming conference will start with the pre-congress airway and regional anesthesia workshops in our world-renowned Chula Soft Cadaver Surgical Training Center. Several exciting and up-to-date scientific sessions are lined up within the three-day academic program. There will be lots of knowledge-sharing and engaging discussions during this friendship environment conference. I believe our collaboration’s power will bring us further and faster and benefit our patient’s safety.

I would like to extend my warm welcome to experts, professional colleagues, juniors, trainees and nurse anesthetists worldwide, especially in ASEAN countries. We hope this will be a time to reconnect, exchange ideas and enjoy a memorable time together in our vibrant and cheerful Bangkok.
