Does intravenous lidocaine added to nonsteroidal anti-inflammatory drugs reduce pain during colposcopy? A prospective randomized double-blind study

Abstract

OBJECTIVES: In recent years, lidocaine infusion for pain management during long operations is becoming more widespread in anesthesiology practice. However, only a limited number of studies have reported the intravenous use of lidocaine for short-term interventions. The aim of this study was to investigate the effectiveness of intravenous lidocaine use in pain management during colposcopic cervical biopsy and endocervical curettage (ECC). MATERIAL AND METHODS: Patients between the ages of 18 and 65 years with abnormal cytological findings or who were determined to be human papillomavirus (HPV)-positive were included in this randomized double-blind study. The lidocaine group (Group L, n = 30) was intravenously administered 50 mg dexketoprofen + 1.5 mg/kg lidocaine in 10 mL saline for 3 min 30 min before the procedure. The control group (Group C, n = 30) was intravenously administered 50 mg dexketoprofen in 10 mL saline for 3 min, 30 min before the procedure. During the procedure, pain scores were assessed using the visual analogue scale (VAS). In addition, patients, operator satisfaction and duration of procedure were assessed RESULTS: There were no differences in the demographic data of the groups. Pain scores during biopsy and ECC were significantly lower in Group L than in Group C (p < 0.001). The duration of the procedure was significantly shorter in Group L than in Group C (5.00 ± 0.78 vs 6.12 ± 1.16, respectively; p < 0.001). Patient and operator satisfaction were significantly higher in Group L than in Group C (p < 0.001). CONCLUSIONS: Intravenous lidocaine administration can be used as an alternative approach to reduce pain and increase operator and patient satisfaction during colposcopy-directed biopsy and ECC procedures in office settings.
