Outcome Measures
Primary Outcomes (1)
times to lose consciousness( LOC)
Times to lose of consciousness( LOC) which is defined as an OAA/S score 2 (loss of responsiveness to light tapping on shoulderor mild shaking with voice command to open eyes)
from the first second after administration of the anesthetic drugs and for 1-5 minutes
Study Arms (3)
the control group
PLACEBO COMPARATORthe control group (n =15 ) the patients will receive 20 ml of normal saline IV ,20 minutes before induction of general anesthesia .
Amiophylline (2mg)
ACTIVE COMPARATORAminophylline 2mg:(n = 15) the patients will receive 2 mg/kg intravenous (IV) aminophylline diluted in 20 ml normal saline 20 minutes before induction of general anesthesia
Aminophylline(4mg)
ACTIVE COMPARATORAminophylline 4mg: (n = 15) the patients will receive 4 mg/kg intravenous (IV) aminophylline diluted in 20 ml normal saline 20 minutes before induction of general anesthesia .The study drugs will be given by an anesthetist unaware of the study protocol.
