Outcomes
Primary outcome [1] 304901 0
100 mm visual analogue pain score post spine surgery
Timepoint [1] 304901 0
Post operative numeric rating score of pain after discharge from the Post anesthesia Care Unit. Time-frame: 48 hour post discharge from the Post Anesthesia Care unit..
Primary outcome [2] 304902 0
Total consumption of narcotics 48 hours after discharge from Post anesthesia Care Unit. Narcotic was given intramuscular if the 100 visual analogue pain scale is above 40. This outcome i.e the total consumption dose of meperidine is taken from the hospital records.
Timepoint [2] 304902 0
Total consumption of narcotics post operatively after discharge from the Post anesthesia Care Unit. Time-frame: 48 hour post discharge from the Post Anesthesia Care unit..
Secondary outcome [1] 343561 0
sit-to-stand test:
. 1. Sit in the middle of the chair with your feet flat on the
floor
2.. Rise to a full stand and return to a complete sitting
position.
0 = inability to rise from a chair.
1 = inability to stand without assistance.
2 = ability to stand alone.
Timepoint [1] 343561 0
Time frame: 48 hours after discharge from the Post Anesthesia Care Unit.
Secondary outcome [2] 343562 0
Side Effects: Nausea and vomiting self reported by Likert scale.
Timepoint [2] 343562 0
Time frame: 48 hours after discharge from the Post Anesthesia Care Unit.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The syringes filled with ropivacaine 0,5% or normal saline were numerated according to a hazard table by an anesthesia technician unaware of the study and given to the surgeon to impregnate the gelatin foam to apply on the transverse process of the operated vertebrae on both sides..
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software to numerate the syringes filled with ropivacaine 0,5% or normal saline.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
Lumbar spine instrumentation surgery is known to cause an intense pain in the postoperative period. The pain can originate from surgery on the different structures such as vertebrae, intervertebral discs, dura , ligaments ,joint capsule fascia , muscles and skin . The posterior sensory rami of the spinal nerves connected to sympathetic and parasympathetic nerves innervate these structures and transmit the pain sensation.
In order to decrease opioids usage and side effects, we propose a method that compare the effect of absorbable gelatin sponge impregnated with local anesthetics versus normal saline placed by the surgeon on the transvers process of the operated vertebra, at the end of the surgery, and before closure of surgical plans, on postoperative visual analogue pain score and the amount of meperidine usage for 48h post-surgery.
