Perioperative anaphylaxis in Malaysia: A nine-year retrospective study
Journal
Anaesthesia and Intensive Care
Year

Conclusion
This study of POA in Malaysia found that skin tests were positive in almost all cases that had raised dynamic tryptase, and also in more than 70% of higher grades of POA—thus identifying the causative agent(s). NMBAs and antibiotics were the two most common causative agents of POA. Rocuronium and atracurium were the main agents responsible for NMBA anaphylaxis. The cross-reactivity rate among NMBAs was found to be 58%. Further, it could be estimated that the incidence of Grade 2–4 POA in Malaysia was approximately 1 in 30,000, although this may be an underestimate due to the voluntary nature of reporting, and the possibility that some milder Grade 2 cases of POA were underdiagnosed.

Clinical trials are part of research studies involving patient volunteers that are conducted to find safe and effective treatments for a variety of health conditions. They are critical to the advancement of medicine and improving patient health. Participating in clinical trials offers patients the opportunity to try new and effective treatments that could potentially improve their condition while taking part in vital research that can benefit many future patients.
In Pantai Hospital Kuala Lumpur, clinical trials are carried out under our Clinical Research team.
