A case series supports feasibility of a conscious-sedation approach within a prepared specialist environment, not sedation without contingency planning.
Fifty-four patients underwent transvenous lead extraction using local anesthesia, fentanyl, and midazolam or diazepam. The report described procedural results and some sedation-related hypotension and hypoxia. General-anesthesia and cardiac-surgery backup were immediately available if required.
This was a retrospective series without a randomized general-anesthesia comparison. Fifty-four patients are not 130 independent people merely because 130 leads were targeted. Patient selection, operator skill, technique, and backup capability affect the observed outcomes.
For a procedural safety opinion, preserve the conditions under which feasibility was reported. “Conscious sedation” does not mean no respiratory risk or no rescue resources. The actual setting, monitoring, drugs, and access to emergency support must be compared before applying this experience to another case.
