Intervention/exposure
Study type
Interventional
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.

post operative recovery profile
Recovery excitement score developed by Kegan will be used by the observer to assess degree of agitation upon emerge from sedation (1 -(none)awake and calm, cooperative; 2 –(mild) crying occasionally; 3 –(moderate) irritable/restless, screaming,inconsolable; 4 –(marked) combative, disoriented,thrashing).

Allocation to intervention
Randomised controlled trial
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.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
randomization will be done using a randomisation table created by computer software

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
