To evaluate the efficacy and safety of dezocine combined with lidocaine in local anesthesia for percutaneous testicular sperm aspiration

Pak J Pharm Sci. 2023 Sep;36(5):1381-1388.


A total of 130 patients who underwent percutaneous testicular sperm aspiration from March 2021 to February 2023 were randomly divided into a Dezocine group and a control group. The Dezocine group received a muscle injection of 0.05mg/kg Dezocine 30 minutes before surgery, while the control group received a muscle injection of 0.01ml/kg normal saline. Both groups received 3ml of 2% lidocaine for spermatic cord block anesthesia. The anesthesia onset time, anesthesia duration, numeric rating scale (NRS) score, anesthesia satisfaction rate and incidence of adverse reactions were recorded and compared between the two groups. The statistical results showed that there were significant differences between the two groups in terms of anesthesia onset time, anesthesia duration, anesthesia satisfaction rate, non-steroidal anti-inflammatory drug (NSAID) use within 24 hours after surgery and NRS scores at 15 minutes, 1 hour and 2 hours after surgery. The incidence of adverse reactions in the Dezocine group was lower than that in the control group, but the difference was not statistically significant. The combination of Dezocine and lidocaine for spermatic cord block anesthesia during percutaneous testicular sperm aspiration is safe, effective and associated with fewer adverse reactions. It is suitable for clinical application and promotion in reproductive medicine outpatient surgery.
