The analgesic effect of paracetamol when added to lidocaine for intravenous regional anesthesia.

BACKGROUND: In this study, we evaluated the effect of paracetamol on sensory and motor block onset time, tourniquet pain, and postoperative analgesia, when added to lidocaine in IV regional anesthesia (IVRA). METHODS: Sixty patients undergoing hand surgery were randomly and blindly divided into three groups. All groups received IVRA lidocaine (3 mg/kg) diluted with saline to a total volume of 40 mL. Group 1 received IVRA lidocaine plus IV saline, Group 2 received IVRA lidocaine and paracetamol (300 mg) admixture plus IV saline, and Group 3 received IVRA lidocaine plus IV paracetamol (300 mg). Sensory and motor block onset time, tourniquet pain, and analgesic use were assessed during operation. After tourniquet deflation, visual analog scale (VAS) scores at 1, 2, 4, 6, 12, and 24 h, the time to first analgesic requirement, total analgesic consumption in first 24 h, and side effects were noted. RESULTS: Onset of motor block was shorter and recovery of motor and sensory block was significantly longer in Group 2 (P < 0.05). Intraoperative VAS scores at intraoperative 20, 30, and 40 min were significantly lower in Group 2 (P < 0.05). Intraoperative fentanyl consumption (78 +/- 12, 58 +/- 14, 78 +/- 11 microg, respectively) and the number of patients who required fentanyl for tourniquet pain (13 patients, 3 patients, 9 patients, respectively) were significantly less in Group 2 (P < 0.05). Time to postoperative fentanyl administration was also prolonged (15 +/- 6, 25 +/- 5, 15 +/- 4 min, respectively) in Group 2 (P < 0.05). The quality of surgical anesthesia was better in Group 2 (P < 0.05). Postoperative VAS scores and time of initial analgesic requirement were similar among groups; however, the total amount of diclophenac use was less in Group 2 (P < 0.05). CONCLUSION: The addition of paracetamol during IVRA with lidocaine decreased tourniquet pain, increased anesthesia quality, and decreased postoperative analgesic consumption.

[Pasha-Cath in the treatment of post-thoracotomy pain syndrome]. / Posttorakotomi agri sendromu tedavisinde Pasha-Cath uygulamasi.

Post-thoracotomy pain syndrome is a chronic pain syndrome and is seen in approximately 5-65% of patients after thoracotomy. Post-thoracotomy pain syndrome is generally considered to be neuropathic pain due to intercostal nerve injury. A 21- year-old male patient experienced pain radiating along the incision after the thoracotomy operation. Allodynia and hyperalgesia were determined in the upper part of the incision; visual analogue scale (VAS) score was 10. Gabapentin and amitriptyline were started as medical treatment. Three months later, the patient complained of concentration difficulty at work and in daily life. Medical therapy was planned again. In view of the persisting complaints, epidural pulse radio frequency with Pasha-Cath was scheduled. After 3 weeks and also at 3 months, the VAS was 2. After 6 months, VAS remained at 2. As a result, we concluded that epidural pulse radio frequency with Pasha-Cath is an alternative and effective choice of treatment in post-thoracotomy pain syndrome when the medical treatment alone is not sufficient.

A complication during caudal steroid injection.

BACKGROUND AND OBJECTIVE: Epidural injections in the lumbar spine are provided by caudal, lumbar interlaminar or transforaminal routes. Caudal epidural steroid injections are often used for low back pain. Fluoroscopic guidance has been frequently cited as a requirement for this procedure. In this case report, we demonstrate the importance of fluoroscopic guidance during caudal epidural injection. CASE REPORT: A 60 years old male patient was admitted to our Algology Department for low back pain. After physical examination caudal epidural steroid injection was planned. The caudal space was identified under fluoroscopic control initially using an anteroposterior projection. After the resultant epidurogram demonstrated vascular spread along the caudal epidural space the needle was withdrawn and the procedure was completed after reinserting the needle. CONCLUSION: A careful real time fluoroscopic monitoring should be applied with the injection of opaque material to minimize the risk of vascular injection.
