Comparison of procedural pain scores
| Pain score | Lidocaine spray group (n=100) | Placebo spray group (n=100) | p |
|---|---|---|---|
| VAS during the procedure (cm) | 1.00 (0–6) | 3.00 (0–7) | <0.001* |
| Frequency of VAS ≥4 (%) | 6.0 | 41.0 | <0.001† |
Values are expressed as median (minimum–maximum). The variables were compared with Mann-Whitney U-test and Chi-square (χ2) test. A p<0.05 probability value was considered statistically significant.
*Mann-Whitney U-test, p<0.05.
†Chi-square (χ2) test, p<0.05.
