About this study

The study's hypothesis is LMX4 cream, a topical anesthetic cream, will reduce the pain of infants undergoing Lumbar Puncture (spinal tap).

Read the detailed description

Pain of infants will be measured using the Neonatal Facial Coding System by videotaping the infant's face while they undergo the procedure. A comparison between the group that received active drug and the group that received placebo will allow a measurement of the difference, if any, of the pain experienced during the procedure of the infants.

Conditions: Pain
Being tested: Lidocaine Cream 4%, Placebo
Keywords: pain, lumbar puncture, neonates, infants, emergency department, topical anesthesia, LMX4
Medical subject headings: Pain, Emergencies

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Lidocaine Cream 4%Drug
Also called LMX4
Topical cream, 2g applied under occlusive dressing for 20 minutes prior to the procedure
PlaceboDrug
inactive placebo without LMX4

Study groups in NCT00533468
Study group	Role	What they receive
Active Drug	Experimental	Active 4% Lidocaine topical cream (LMX4 cream) applied under occlusive dressing Receives: Drug: Lidocaine Cream 4%
Placebo	Placebo comparator	Placebo Cream made on same run at factory but without active Lidocaine 4% drug Receives: Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

Neonatal Facial Coding System Score
10 measures of pain, all scored 0 or 1, high score means more pain. No pain would be recorded as zero, maximum pain recorded as 10
Measured: Score was measured at baseline, upon positioning for the procedure, immediately prior to needle insertion, during needle insertion, 1 minute post-needle insertion, and post-procedure when the infant had recovered from the procedure and was swaddled

Secondary outcomes (2)

Time of Procedure
Time, measured in minutes, required to complete procedure from infant's presentation to the Emergency Department
Measured: Infant's stay in the Emergency Department
Percentage of Procedures With Success
Whether the Lumbar Puncture resulted in recovery of spinal fluid that could be sent for usual testing
Measured: During patient's Emergency Department Stay

Adverse events

Other adverse events reported at 5% frequency or more

Group	Serious adverse events	Other adverse events	Deaths
Placebo	0 of 28 (0%)	10 of 28 (35.7%)	0 of 28
Active Drug	0 of 24 (0%)	4 of 24 (16.7%)	0 of 24

Limitations and caveats (from the sponsor): Significant technical limitation was encountered regarding videotaping of infant faces when properly positioned for the procedure, as the research assistant had to be underneath the nurse's arm with the camera adjacent to the nurse's breast. This resulted in many exclusions of patients enrolled by the male research assistants as the camera was not in proper position. The many exclusions reduced the study's power to reach a statistically significant difference.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Dec 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Neonatal Facial Coding System Score (time frame: Score was measured at baseline, upon positioning for the procedure, immediately prior to needle insertion, during needle insertion, 1 minute post-needle insertion, and post-procedure when the infant had recovered from the procedure and was swaddled). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00533468.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Dec 2022; AzTrials last refreshed its copy on 8 Nov 2026.
