single-shot spinal

Full Definition

Single-shot spinal anesthesia involves a single injection of local anesthetic, often combined with opioids, into the cerebrospinal fluid to provide dense sensory and motor blockade for surgical procedures. In cardiac anesthesia, spinal techniques may be used as adjuncts to general anesthesia to reduce opioid requirements, provide postoperative analgesia, and potentially reduce perioperative morbidity. However, anticoagulation protocols in cardiac surgery require careful timing and consideration of bleeding risks.

Usage

Usage note: Specify drug combinations and timing relative to anticoagulation when documenting spinal techniques.
