Spinal anesthesia for ambulatory surgery: current controversies and concerns

Area of Science:

• Anesthesiology
• Ambulatory Surgery
• Regional Anesthesia

Background:

• General anesthesia is common in ambulatory surgery, but spinal anesthesia is often avoided due to concerns about delayed recovery.
• Renewed interest in spinal anesthesia stems from improved outcomes observed in hospitalized patients undergoing total joint arthroplasty.
• This review critically examines spinal anesthesia versus fast-track general anesthesia in the outpatient setting.

Purpose of the Study:

• To compare the efficacy and outcomes of spinal anesthesia versus fast-track general anesthesia for ambulatory surgery.
• To evaluate the potential benefits of spinal anesthesia, such as reduced postoperative pain and opioid use.
• To assess whether improved outcomes seen in hospitalized patients are applicable to the outpatient population.

Main Methods:

• Critical review of existing literature comparing spinal anesthesia and fast-track general anesthesia in outpatient settings.
• Analysis of purported benefits of spinal anesthesia, including avoidance of airway manipulation and general anesthesia drug side effects.
• Evaluation of fast-track general anesthesia techniques, emphasizing opioid-sparing and minimal neuromuscular blockade.

Main Results:

• Spinal anesthesia may offer benefits like avoiding airway manipulation and reducing postoperative pain and opioid needs.
• Improved outcomes in hospitalized patients may not directly translate to healthier outpatients.
• The superiority of spinal anesthesia over optimized fast-track general anesthesia techniques in outpatients is not clearly established.

Conclusions:

• The advantages of spinal anesthesia for outpatient procedures remain uncertain.
• Further research is needed to clarify the specific goals and outcomes associated with spinal anesthesia in the ambulatory setting.
• The comparative effectiveness against modern fast-track general anesthesia techniques requires more investigation.
