Condition(s) targeted: Pain

Intervention: local (Other); intravenous (Other); 0.33% ropivacaine 250ml (Drug); flurbiprofen axetil 150mg,palonosetron 0.5mg,pentazocine 240mg. (Drug)

Phase: Phase 4

Status: Completed

Posterior thoracolumbar operation always chooses general anesthesia. Due to surgical trauma and rich periosteum and joint capsule innervation, patients after general anesthesia immediately feel acute pain. The use of appropriate postoperative analgesia in patients with thoracolumbar surgery is beneficial to postoperative recovery. Infusions of local anaesthetic via multilumen catheters that deliver directly to wound sites have been used for postoperative analgesia in procedures. Reducing the morbidity from both pain and nausea will make the mode of analgesia a better tolerated and more palatable option for patients. The aim of this study is to examine the effects of using local anaesthetic infusion catheters following posterior thoracolumbar surgery, and compares the outcomes of patients managed using intravenous analgesia pump infusion of systemic opioids.

Clinical Details

Official title: Pain Treatment in Posterior Thoracolumbar Operation a Randomized Study to Assess the Effect of Local Analgesia After Operation

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: pain

Secondary outcome:


comprehensive evaluation

Detailed description: All 71 adult patients were prospectively included and randomized to either the local (L) group (n=35) or the intravenous (V) group (n=36) by using a random number table: the test group were treated with local analgesia infusion pump of 0. 33% ropivacaine through the wound for postoperative analgesia, while the control group were treated with intravenous analgesia pump infusion of flurbiprofen axetil,palonosetron, pentazocine. At 2, 4, 6, 12, 24, 36, 48 hours after operation, postoperative pain visual analogue scale(VAS) scores and sedation Ramsay scores were used to evaluate the level of pain and sedation, and investigators documented the comprehensive evaluation of patients with pain control system, and the incidence of adverse reactions. At 24, 48 hours investigators observed the wound whether inflammation and exudation or not, and the removal of penetration catheter sent to clinical laboratory for bacterial culture. Investigators also recorded the length of time to discharge and called to ask pain conditions at the first 3 months.


Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.


Inclusion Criteria: 1. ASA Ⅰ ~ Ⅱ patient undergoing elective posterior thoracolumbar operation 2. between 18 and 70 years of age Exclusion Criteria: 1.
