General versus epidural anesthesia for lumbar microdiscectomy

Area of Science:

• Neurosurgery
• Anesthesiology
• Health Economics

Background:

• General anesthesia (GA) is common for lumbar microdiscectomy (LMD), but regional anesthesia options like epidural anesthesia (EA) are also used.
• Limited comparative studies exist on the cost-effectiveness of EA versus GA for LMD.

Purpose of the Study:

• To compare the costs, operating room efficiency, and complication rates of epidural anesthesia (EA) versus general anesthesia (GA) in patients undergoing lumbar microdiscectomy (LMD).

Main Methods:

• Retrospective analysis of 850 LMD procedures performed under EA (n=573) or GA (n=277).
• Data collected on patient costs, operating room time, surgery duration, and complication rates.
• All procedures performed by the same surgeon between April 2003 and May 2013.

Main Results:

• EA resulted in significantly lower patient costs compared to GA (p<0.01).
• A statistically significant difference was observed in operating room time between the EA and GA groups (p<0.01).
• No significant difference in surgical duration was found between the two anesthetic methods (p>0.05).

Conclusions:

• Epidural anesthesia (EA) offers significant healthcare cost savings for lumbar microdiscectomy (LMD).
• EA enhances operating room efficiency and can lead to less nerve root manipulation, improving comfort and efficacy.
• EA is a cost-efficient, reliable anesthetic method for LMD that does not compromise surgical success rates.
