Outcomes for Lumbar Decompressions With Use of Liposomal Bupivicaine

A Double Blinded Randomized Control Trial in Outcomes for Lumbar Decompressions With Use of Liposomal Bupivicaine

Evaluate the benefit of using liposomal bupivicaine in lumbar laminectomies in terms of length of stay, IV narcotic use, 30-day narcotic use, visual analog score (VAS) and 30-day readmissions

Study Overview

• Status: Recruiting
• Conditions: Lumbar Spinal Stenosis
• Intervention / Treatment: Drug: Liposomal bupivacaine

Detailed Description

Recent evidence suggests the use of liposomal bupivicaine (LB) in lumbar spine surgery shortens length of hospital stay and overall post-operative narcotic use. Studies have shown its utility in single level microdiscectomies and lumbar fusions, but there have been no publications regarding lumbar laminectomies and associated outcomes with LB. The investigators' hypothesis is that LB will significantly shorten inpatient stays as well as overall narcotic usage in single, double or multi-level lumbar laminectomies.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall length of hospital stay from hospital admission to hospital discharge	Length of stay will be measured in hours	From date of hospital admission until date of hospital discharge, assessed up to 2 weeks.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
IV narcotic usage	Tracked by patient's electronic medical record	From date of hospital admission until date of hospital discharge, assessed up to 2 weeks.
30-day narcotic usage	Narcotic usage will be assessed via state narcotic databases.	30-day post surgery
Change in Visual Analog Pain scale scores	The scale is called the Visual Analog Pain scale. This scale provides a measure of the patient's reported level of pain . Patients will be asked to rate their pain level using the Visual Analog Pain scale. This scale uses numbers, 1-10, with 1 being no pain and 10 being the worst pain. It also uses faces depicting no pain up to the worst pain. Lower reported scores indicate the patient has little to no pain, which is desirable.	Screening, Day of Procedure, Prior to Hospital Discharge (Post-op, Up to 2 weeks), Up to 30-days post-surgery (Follow-Up#1) and up to 12-months post-op follow up
30-day readmission rates	Occurrences of readmission will be tracked by patient's electronic medical record	Day 30
