Brief summary

This randomized clinical trial studies local anesthetic (EMLA) cream in younger patients undergoing lumbar punctures (LP). A local anesthetic cream may be effective for numbing the skin and reducing movement when applied prior to lumbar punctures and may reduce the amount of sedation necessary

Detailed description

PRIMARY OBJECTIVES: I. To determine whether the application of a topical anesthetic (EMLA cream) to the LP site will decrease the total dose of propofol administered to pediatric oncology patients who are being sedated for LPs compared to application of a topical placebo cream. SECONDARY OBJECTIVES: I. To determine whether the use of EMLA cream decreases complication rates from sedation. II. To determine whether the use of EMLA cream decreases traumatic lumbar punctures. III. To determine whether the use of EMLA cream shortens recovery time. IV. To determine practitioner and parent satisfaction with the use of EMLA cream. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive topical EMLA cream 60 minutes to 4 hours prior to the LP followed by standard sedation with fentanyl citrate and propofol. ARM II: Patients receive topical placebo cream 60 minutes to 4 hours prior to the LP followed by standard sedation with fentanyl citrate and propofol. After completion of study treatment, patients are followed up within 1 week.

Inclusion criteria

Pediatric oncology patients undergoing a lumbar puncture in the Pediatric Sedation Suite; patients may or may not be receiving intrathecal chemotherapy

Exclusion criteria

Patients undergoing additional procedures during the same anesthetic such as bone marrow aspirate or biopsy will be excluded because they will likely require higher doses of propofol than those undergoing LP alone Patients who are allergic to or not tolerant of EMLA cream, propofol, or fentanyl will be excluded Patients who are pregnant will be excluded Patients having their LPs done by students will be excluded

Recruitment details

Originally 33 participants were registered, with 170 trials; each participant had between 1-14 trials (median=4). Five of these participants did not end up receiving the procedure and 1 was a screen fail, leaving 27 participants with between 1-14 trials (median=5).

Outcome results

Primary

Total Dose of Propofol Administered to Each Patient

Analyzed using descriptive statistics and mixed model regression methods. Raw mean total dose administered and raw percentage of times additional propofol was administered will be presented by sedation group treating each event (sedation with lumbar puncture) as the unit. T-test and chi-square tests will be performed as appropriate.

Time frame: 20 minutes after sedation

Population: Participants were not randomized. Trials were randomized so we will have to use the trials to report by arm

Comparison: Raw mean total dose administered and raw percentage of times additional propofol was administered will be presented by sedation group treating each event (sedation with lumbar puncture) as the unit. T-test and chi-square tests will be performed as appropriate for the outcome. GEE methods will be used when analyzing the percentage of times additional propofol was administered.
