Comparison of the addition of fentanyl and sufentanil to anesthesia and its effects on urinary retention after spinal anesthesia: a systematic review and meta-analysis

Introduction: two drugs, fentanyl and sufentanil, are drugs added to the anesthetic trial, which have been used more than other drugs, however, there is still no detailed information about the safety of adding these two drugs to the anesthetic drug in the event of urinary retention in Therefore, the present study was conducted with the aim of comparing the addition of fentanyl and sufentanil to the anesthetic drug and its effects on urinary retention after spinal anesthesia. Methods: This study was conducted as a systematic review and meta-analysis based on the PRISMA statement. Searching MEDLINE, CENTRAL and EMBASE, Web of Science, Scopus, Mag Iran and SID databases using the keywords anesthesia, spinal anesthesia, phenethyl, sufentanil, bupivacaine, ropicaine, levobopiva, regional anesthesia, urinary retention and after Anesthesia was performed with the help of Boleyn operatives. Results: There was no significant difference in urinary retention (RR=1.02 [0.70-1.49]; 95% CI) between the intervention and control groups; Also, there was no significant difference between fentanyl or sufentanil (Chi=0.13/I=0%). Conclusion: Adding fentanyl or sufentanil to the anesthetic drug during spinal anesthesia has no effect on urinary retention after surgery
