Description of intervention(s) / exposure
40 children, were randomized to receive either Propofol infusion started at a rate of 2mg/kg over 10 min then the infusion rate of 50 ug/kg/min were adjusted until patient fall a sleep and reach a sedation score 5-6 according to Ramsay sedation score .Or to receive Dexmedetomidine infusion started at a rate of 0.5ug/kg intravenously for 10 min , Then a continous infusion of 0.5ug/kg/hr was adjusted until patient fall asleep and the sedation score became 5-6 and be able to be positioned.
In both groups,Immediately before the procedure 0.5 mg/kg Ketamine was administered intravenously,Then Incremental doses of Ketamine 0.3mg/kg was administered intravenously to maintain sedation score 5-6 intraoperatively.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Children between 6-12years. diagnosed as either acute lymphocytic leukemia or acute myeloid leukemia with ASA physical status I–II scheduled for for diagnostic or prognostic lumbar puncture or bone marrow biopsy. will be recruited.
Patients with ASA physical status III–IV, age less than6 years or more than 12 years,congenital heart disease, cardiomyopathy, any rhythm other than sinus rhythm, liver or renal disease, upper respiratory infection, behavioral problems, patient on anticoagulant, beta blocker, clonidine, or digoxin will be excluded.
Patients will be randomly allocated using computer generated
numbers. Allocation will beconcealed using
opaque sealed envelopes that will be opened just prior
to induction of general anaesthesia.

Statistical methods / analysis
Data will be statistically described in terms of mean +-standard deviation , or frequencies (number of cases) and percentages when appropriate. Data will be tested for normality using Kolmogorov Smirnov test. Comparison between the two study groups will bedone using Student t test for independent samples. p values less than 0.05 will be considered statistically significant. All statistical calculations will be done using computer programs SPSS (Statistical Package for the Social Science; SPSS Inc., Chicago, IL, USA) version 15 for Microsoft Windows

Summary
Brief summary
Context: Dexmeditomedine infusion in oncology pediatric patients is used to perform repeated lumbar puncture and bone marrow aspiration. Objective: We hypothesized that dexmetomedine could be effectively used as a sedative/analgesic agent for children requiring the above procedures,We designed our study to compare the effects of dexmedetomidine infusion versus propofol infusion on perioperative hemodynamics, sedation, pain, and recovery scores for invasive procedures in pediatric oncology patients. Design: Randomised double blind study Patients or other participant: Forty ASA 1 or 2 children, 6–12 yearsr of age, with hematological cancer , were randomized to receive either propofol infusion ( Group A)or dexmedetomidine infusion (Group B) during anesthesia for diagnostic or prognostic short duration procedures . Intervention(s) : Patients were assigned to receive either Propofol infusion started at a rate of 2mg/kg over 10 min then the infusion rate of 50 ug/kg/min were adjusted until patient fall a sleep and reach a sedation score 5-6 according to Ramsay sedation score Or to receive , Dexmedetomidine infusion started at a rate of 0.5ug/kg intravenously for 10 min, Then a continous infusion of 0.5ug/kg/hr was adjusted until patient fall asleep and the sedation score became 5-6 and be able to be positioned. In both Groups, Immediately before the procedure 0.5 mg/kg Ketamine was administered intravenously .
