Ropivacaine 0.4% iontophoresis versus continuous catheter infusion after iliac crest bone grafting in lumbar spine surgery

Continuous wound infusion of ropivacaine for the control of pain after thoracolumbar spinal surgery: a randomized clinical trial

“…This group received an initial wound infiltration with 6 ml 1 % ropivacaine (100 mg; AstraZeneca AB, Sweden) and followed by continuous infusion with 0.33 % ropivacaine via a double lumen catheter system at a rate of 5 ml/h (Disposable Postoperative Local Analgesia System, Beijing Heng Yuan Tongji Medical Technology Corporation, China) for 48 h. Patient in L group did not receive postoperative intravenous continuous constant-dose analgesia (ICCA) for pain control. The V group (n = 36) relied on ICCA for postoperative pain control involved flurbiprofen axetil 150 mg, pentazocine 240 mg and palonosetron 0.5 mg in 100 ml normal saline, at a rate of 2 ml/h [5]. All patients expanded on the use of the supplementary analgesic (flurbiprofen 50 mg intravenous injection) if necessary (VAS C4).…”

“…This technique remains effective in spinal surgery. Recently, Rushdi et al [5] reported that the wound was infused with a solution of ropivacaine 0.4 %, suggesting the potential for the use of this method in major spinal surgery. The current study aimed to test the analgesic efficacy of wound infiltration with 1 % ropivacaine followed by an infusion of 0.33 % following thoracolumbar spinal surgery.…”

Comparing the effects of Bupivacaine and Ropivacaine Instillation for Postoperative Analgesia in Patients Undergoing Lumbar Spine Surgery: A Prospective Randomised Double Blind Study

“…The probable mechanism of pain relief could be due to the anaesthetic effect of bupivacaine acting on the pain receptors distributed in the soft tissues and the nerve endings exposed in the wound right from the skin to the dura meninge (skin, paraspinal muscle, posterior longitudinal ligament, dorsal annulus, facet joint capsule, nerve root which was under compression and the spinal meninges the dura supplied by recurrent nerve of Von Luschka). 5 Recently, Rushdi et al reported that the wound was infused with a solution of ropivacaine 0.4 %, suggesting the potential for the use of this method in major spinal surgery 6 . The present study was designed to evaluate and compare the effectiveness of wound instillation technique for postoperative analgesia after lumbar spine discectomy and laminectomy by using 20 ml bupivacaine (0.25%) or 20 ml ropivacaine (0.25%).…”
