Forced coughing versus local anesthesia and pain associated with cervical biopsy: a randomized trial.

Abstract

Cervical biopsy often causes discomfort and pain. To compare local anesthesia (1% lidocaine) with forced coughing as pain relief, we quantified the actual pain experienced during cervical punch biopsies. For a prospective trial conducted at the Medical University of Vienna, 68 women undergoing cervical punch biopsies for assessment of abnormal cervical smears were randomized in 2 pain relief treatment groups. Patients' discomfort was assessed immediately after taking the biopsy using at 10-cm visual analog scale. No statistically significant difference was found between pain scores recorded for the 2 groups (P = .47, 95% confidence interval [CI], -0.4 to 1.3 cm). However, when local anesthesia was applied, the examination was significantly prolonged by a median of 2.11 min (P < .001; 95% CI, 1.6-2.8). Forced coughing during cervical biopsies reduces patients' discomfort to the same extent as local anesthesia, but is associated with a significantly reduced examination time.
