Abstract
BACKGROUND: Insertion of peripherally inserted central catheters (PICC) is a commonly performed procedure in both preterm and term infants. Tetracaine 4% gel (Ametop; Smith & Nephew Inc, St. Laurent, Quebec), a topical anesthetic, although reported to be effective for reducing the pain of venipuncture in neonates, has not been investigated for the management of pain associated with the PICC procedure. PURPOSE: To determine the efficacy of tetracaine gel for managing the pain associated with the PICC procedure in preterm and term infants. METHODS: A double-blind, placebo-controlled, randomized controlled trial (RCT) design was used. Infants undergoing nonurgent PICC insertion were randomized to receive either the treatment (1.0 g of tetracaine 4% gel) or placebo control (1.0 g of eucerin-plus cream) applied to the skin under occlusion for 30 minutes before the procedure. Data on the behavioral (facial expression) and physiologic (heart rate and oxygen saturation) indicators of pain were collected via videotaping and computer monitoring throughout the procedure. Data then were coded and measured by independent observers using the Premature Infant Pain Profile (PIPP; Stevens et al, 1996), and analyzed using descriptive statistics and repeated-measures analyses of variance. RESULTS: Forty-nine infants, gestational age 27 to 41 weeks (mean = 33; SD = 4.2) and age at time of insertion 2 to 85 days (mean = 18; SD = 22.5) participated. No differences were found between the groups at the time of randomization. There were no adverse cardiorespiratory events or local skin reactions in either group. There was a significant within-subjects main effect of time across the procedure (F[48,3] = 11.03; P < 0.0001). There was no significant between-subjects main effect of group (F[48,1] = 0.11; P = 0.74) and no (group x time) interaction (F[48,3] = 0.45; P = 0.72). CONCLUSION: Tetracaine gel was not effective for pain relief for PICC insertion in infants. Its use for pain relief cannot be recommended based on the results of this study. Other pharmacologic, behavioral, and physical interventions should be investigated for safety and relief of procedural pain in this population of infants.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
