The Interest of the Nitrous Oxide During Intravesical Injection of Botulinum Toxin A

Summary

Second line treatment for detrusor hyperreflexia is the intravesical BTX-A injections. First 300 units Botox are diluted with 30 ml of preservative-free saline. Using a rigid cystoscope and an injection needle, BTX-A is injected into 30 sites within the detrusor muscle. The used of KALINOX® (50% nitrous oxide and oxygen) inhalation has demonstrated analgesic efficacy in various procedures (obstetric, liver biopsy, transrectal ultrasound guided prostate biopsy, emergency) The aim of this study is to investigate the safety and efficacy of analgesia with N2O/O2 inhalation for detrusor BTX-A injections using a rigid cystoscope.
