Comparison of bacteriostatic saline and buffered lidocaine efficacy in cervical anesthesia in diagnostic curretage:A double blind randomized clinical trial

Introduction: Usage of diagnostic curratage in clinical practice is very common. The aim of this study was to compare the efficacy of bacteriostatic saline and buffered lidocaine in cervical aneasthesia. Methods: In this double-blind randomized clinical trial sixty patients who reffered to gynecology ward of Shariati hospital, Tehran during 2001 - 2002 were randomly a Hocated into two groups. The severity ofpain during dilatation and curratage (D&C) operation and 30 minutes after operation was assessed by 21 point Box Scale. Statistics analysis was performed by SPSS 11 software. Results: Severity of pain during D&C operation and 30 minutes after that was significantly much more in saline group than lidocaine group (respectively, P=0.007, P=0.001). Four patients in lidocaine group and 15 patients in saline group were excluded from the study because of confounding factors (such as complications or low efficiency). Conclusion: It seems that in Iran, bacteriostatic saline in cervical aneasthesia for the purpose of diagnostic curratage was not efficient.
