Abstract
Traditionally, general or regional anesthesia has been employed during endourologic procedures. The success of sedative-analgesic sedation during SWL prompted an investigation into its use in minor endourologic procedures. We compared intravenous alfentanil-midazolam anesthesia (n = 30) with spinal anesthesia (n = 35) during procedures such as ureteroscopy and stent placement using physiologic measures and patient and anesthetist ratings. The former series was prospective; the latter was retrospective. Physiologic measures remained stable and oxygen saturation was above 90% in all patients in both groups during the procedures. The average anesthesia and recovery room times were significantly shorter for patients given alfentanilmidazolam: 23.3 ν 36.1 minutes and 85.5 ν 179.6 minutes, respectively (P < 0.001; t-test), and this difference reduced the anesthesia cost an average of 46%. The anesthetists rated the intravenous regimen satisfactory in 92% of the patients, and 94% of the patients rated the procedure as comfortable. All 18 of the patients who had previously had spinal anesthesia considered alfentanil-midazolam superior. Intravenous alfentanil-midazolam sedation anesthesia can provide adequate analgesia for many minor endourologic procedures while shortening the anesthesia recovery time.Keywords
