St. Jude Children's Research Hospital is studying the best ways to prevent pain during and after procedures such as bone marrow aspiration and lumbar puncture with intrathecal (in the spinal fluid) chemotherapy. Researchers will study the effectiveness of combining anesthetics (medicines that help people sleep) and analgesics (medicines that relieve pain). Researchers believe that a combination of fentanyl (analgesic) and propofol (anesthetic), along with applying the skin-numbing-cream EMLA or L.M.X4™ on the area where the procedure is performed, will provide better pain control. Each patient enrolled on this study will have three different anesthetic combinations for three different procedures, in order to determine which combination worked best for each child.

Study summary:

The study focusses on the following primary aims: - To compare 0.5 mg/kg versus 1.0 mg/kg of fentanyl to control pain in patients who have a BMT/LPIT procedure in the context of propofol anesthesia and topical anesthesia with EMLA or L•M•X 4™cream (or when necessary, lidocaine for injection). - To compare placebo versus fentanyl (0.5 mg/kg or 1.0 mg/kg) in these same patients. The first BMT/LPIT for which patients receive any fentanyl will be used in this comparison. The study focusses on the following secondary aims: - To determine which dose regimen ensures best conditions to perform bone marrow aspiration (lack of motion) and maintains hemodynamic and respiratory stability as indicators of adequate levels of analgesia during bone marrow aspiration. - To evaluate the safety and complications for each dose regimen.


Inclusion Criteria: - Patients undergoing bone marrow aspiration (unilateral), with lumbar puncture and intrathecal chemotherapy. - Age 2 to 17 years - ASA I-III - Patients with acute lymphoblastic leukemia or lymphoblastic lymphoma in remission or on the day of anticipated remission procedures occurring at the end of remission induction. - Patients must have three anticipated bone marrow aspirates and lumbar punctures with intrathecal chemotherapy remaining in their treatment Exclusion Criteria: - Newly diagnosed patients - Patients with low platelet count (less than 50000) - Patients undergoing bone marrow biopsy in addition to bone marrow aspiration - Age less than 2 years or over 17 years - ASA IV-V - Patients taking opioid medication for pre-existent pain for more than 2 weeks at the time of the procedure - Neurological impairment that would increase susceptibility to opioids (Down's syndrome) - Clinical contraindications for general anesthesia (large mediastinal mass) or specific use of propofol, Fentanyl, EMLA, L•M•X 4™ or Lidocaine for injection
