Conditions
Summary
Incisional pain is a common complication after surgery and is an important cause of delayed postoperative recovery, increased length of hospital stay, increased risk of wound infection and respiratory/cardiovascular complications, as well as an important medical, social, and economic problem. Prevention and treatment of postoperative incision pain remains challenging. Local Infiltration Anaesthesia (LIA) for surgical incisions with an anti-inflammatory and analgesic combination has been reported to be effective in reducing postoperative pain, but there is a gap in the research on the optimal concentration of anti-inflammatory drugs in the anti-inflammatory and analgesic combination during local infiltration. The aim of this study was to investigate the optimal concentration of anti-inflammatory drugs in the anti-inflammatory-analgesic combination solution used for local infiltration of spinal surgical incisions to prevent postoperative pain.

Interventions
At the preoperative visit, patients will sign informed consent and learn to use the patient-controlled analgesia (PCA) pump and assess pain with the visual analogue scale (VAS). Standard general anesthesia will be induced and maintained with sufentanil, propofol, cisatracurium or rocuronium, and sevoflurane. Before incision, neurosurgeons will administer the allocated local infiltration solution. 0.5ml of diprospan will be diluted to 30 ml with 15 ml of ropivacaine in 0.9% NaCl to prepare diprospan at concentrations of 0.012%, respectively. The surgeon will use a 22 G straight needle for local infiltration anesthesia near the planned incisions. Postoperatively, patients will receive tropisetron and a PCA pump delivering sufentanil and ondansetron. PCA usage (effective/ineffective presses) and supplemental analgesia with Tylenol or loxoprofen will be monitored for 48 hours and up to 3 months. Dosages and intraoperative parameters will be closely recorded throughout.
