Summary

This trial is comparing two types of spinal anesthesia for patients undergoing knee replacement surgery to see if they are ready to go home on the same day as their surgery. Data will be collected during the hospital stay

Who is the study for?
This trial is for adults scheduled for knee replacement surgery who are healthy enough to be discharged on the same day. Participants must not have conditions that would interfere with spinal anesthesia or recovery, such as allergies to local anesthetics, bleeding disorders, infection at the injection site, or severe heart or neurological issues.
What is being tested?
The study compares two types of spinal anesthesia drugs: Mepivacaine and Bupivacaine. It's designed to see which one allows patients to be ready for discharge sooner after knee replacement surgery. Patients will be randomly assigned a drug without knowing which one they receive (double-blind).
What are the potential side effects?
Possible side effects from both Mepivacaine and Bupivacaine include low blood pressure, headache, backache, nausea or vomiting. Rarely there might be nerve damage leading to weakness or numbness in lower limbs.
