Summary
Continuous spinal anesthesia using isobaric 2% lidocaine with microcatheters proved ineffective. Maintaining the anesthesia level was challenging, requiring repeated doses and causing patient discomfort during surgery.
Area of Science:
- Anesthesiology
- Neurosurgery
- Pharmacology
Context:
- Continuous spinal anesthesia (CSA) is an alternative to general anesthesia for prolonged lower abdominal surgeries.
- Microcatheter techniques offer potential for targeted drug delivery and improved patient comfort.
- Isobaric 2% lidocaine is a commonly used local anesthetic for spinal procedures.
Purpose:
- To evaluate the clinical efficacy and safety of isobaric 2% lidocaine administered via a microcatheter for continuous spinal anesthesia.
- To determine the feasibility of maintaining adequate anesthesia levels throughout surgical procedures using this technique.
Summary:
- Nine patients undergoing lower abdominal surgery received continuous spinal anesthesia with isobaric 2% lidocaine via a 27G microcatheter.
- The mean initial dose was 32.3 mg, with a mean total dose of 51.3 mg.
- Three patients required protocol suspension due to difficulties in maintaining anesthesia levels, necessitating repeated injections and causing discomfort.
Impact:
- The microcatheter technique with isobaric 2% lidocaine was found to be ineffective for maintaining consistent anesthesia levels in CSA.
- Challenges in maintaining anesthesia and patient discomfort highlight limitations of this specific approach.
- Further research is needed to optimize microcatheter techniques or explore alternative anesthetic agents for prolonged spinal anesthesia.
