Objective: To investigate the application value and safety of peripheral prostate nerve block (PPNB) combined with dezocine in transrectal prostate biopsy.
Methods: Using a random number table, we divided 97 patients undergoing prostate biopsy in our hospital from October 2018 to October 2020 into an experimental group (n = 49) and a control group (n = 48), the former anesthetized by PPNB combined with dezocine and the latter by PPNB only. We compared the hemodynamic indexes before operation, during puncturing and at 5 minutes after operation, the pain scores during the movement of the probe in the rectum, at puncturing and at 5 minutes after surgery, and the adverse reactions to anesthesia between the two groups of patients.
Results: The heart rate was significantly lower in the experimental group than in the control during puncturing and at 5 minutes after operation (P < 0.05), while the mean arterial pressure (MAP) and blood oxygen saturation (SpO2) were remarkably higher in the former than in the latter group during puncturing (P < 0.05). The Visual Analogue Scale (VAS) score for pain was markedly lower in the experimental group than in the control during the movement of the probe in the rectum, at puncturing and at 5 minutes after surgery (P < 0.05). There was no statistically significant difference in the total incidence rate of adverse reactions to anesthesia between the two groups (P > 0.05).
Conclusion: PPNB combined with dezocine for prostate biopsy is more conducive to maintaining the stability of the patient's hemodynamics, and has a good analgesic effect and a high safety.
