Bronchial asthma with recent changes	o Recent change of symptoms after admission for surgery. o Hx of using rescue short acting beta blockers (SABA). o No history of taking oral corticosteroids	⁃ Start ICS ⁃ Consider LABA ⁃ SABA preoperatively if no LABA. ⁃ OCS for 3–5 days preoperatively.
Moderate bronchial asthma	o Daily symptoms of bronchial asthma. o Current Taking of LABA. o Occupational use of OCS. o Current taking of ICS.	⁃ Continue ICS ⁃ Continue LABA. ⁃ SABA preoperatively if no LABA ⁃ OCS for 3–5 days preoperatively
Severe bronchial asthma	o Daily and sever symptoms of asthma. o Use of ICS o Use of LABA o Daily use of OCS.	⁃ Continue ICS. ⁃ Continue LABA. ⁃ SABA preoperatively if no LABA. ⁃ Increased dose of OCS for 3–5 days preoperatively.
