Analgesic effect of heated oxybuprocaine gel in transrectal ultrasound guided prostate biopsy
Objective To investigate the effect of intrarectal local anesthesia (IRLA) with heated oxybuprocaine gel on pain during transrectal ultrasound guided prostate biopsy (TRUSPB).Methods A total of 150 cases patients who underwent TRUSPB in Huzhou Central Hospital from January to June 2023 were prospectively taken into.The patients were randomly divided into group A (routine group),group B (oxybuprocaine gel for IRLA at room temperature) and group C (oxybuprocaine gel for IRLA at 40℃),with 50 cases in each group.Nurses who were unaware of the anesthesia type used visual analog scale (VAS) to score the pain level of patients at each stage (VAS Ⅰ:when the ultrasound probe was inserted into the rectum;VAS Ⅱ:during the biopsy;VAS Ⅲ:30 minutes after biopsy),and the incidence of complications after biopsy were compared.Results The VAS Ⅱ score of group C was lower than that of group A and group B,and the difference was statistically significant (P<0.05).There was no statistically significant difference (P>0.05) in the VAS Ⅰ,VAS Ⅲ scores,and incidence of complications after biopsy among the three groups.There was no allergic reaction to oxybuprocaine gel.Conclusion In TRUSPB,IRLA with heated oxybuprocaine gel can effectively control pain without increasing incidence of complications.
