Spinal Anesthesia Using Ropivacaine Leads to Earlier Ambulation After Total Hip Arthroplasty

Area of Science:

• Anesthesiology
• Orthopedic Surgery
• Pharmacology

Background:

• Spinal anesthesia is favored for total hip arthroplasty (THA) due to low complication rates.
• Bupivacaine, a common local anesthetic, has a long duration of action, potentially delaying patient recovery.
• Ropivacaine is a less-studied alternative that may offer shorter-acting properties for faster neuraxial blockade recovery.

Purpose of the Study:

• To compare the efficacy and recovery profiles of ropivacaine versus bupivacaine spinal anesthesia in primary unilateral THA patients.
• To evaluate postoperative ambulation, post-anesthesia care unit (PACU) transition times, and complication rates between the two anesthetic agents.

Main Methods:

• Retrospective review of 503 primary unilateral THA patients who received either ropivacaine or bupivacaine spinal anesthesia.
• Comparison of patient demographics including age, sex, and body mass index.
• Analysis of primary outcomes: ambulation time and distance, PACU transition time, and incidence of selective complications.

Main Results:

• The ropivacaine group (227 patients) demonstrated significantly superior ambulation time and distance compared to the bupivacaine group (276 patients).
• Patients receiving ropivacaine experienced quicker post-anesthesia care unit transition times.
• Complication rates were equivalent between the ropivacaine and bupivacaine groups.

Conclusions:

• Ropivacaine provides a distinct advantage over bupivacaine for spinal anesthesia in THA, particularly when rapid patient recovery is a priority.
• The findings strongly support the consideration of ropivacaine, especially in ambulatory THA settings.
• Ropivacaine facilitates enhanced recovery pathways following total hip arthroplasty.
