Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of ropivacaine, ropivacaine plus tramadol and ropivacaine plus morphine in patients undergoing minor hand surgery].
In our study we aimed to compare the effects of ropivacaine alone, ropivacaine plus tramadol HCl, and ropivacaine plus morphine HCl used as intravenous regional anesthesia (IVRA), on duration to the initiation of analgesia, total analgesia time, analgesic requirement, sedation levels and hemodynamic parameters. 53 patients undergoing minor hand surgery were included into the study. Patients were randomly divided into three groups to receive 40 ml of ropivacaine 0.2 % (Group R, n=18), ropivacaine 0.2 % plus 1 mg/kg tramadol HCl (Group RT, n=18), and ropivacaine 0.2 % plus 0.1 mg/kg morphine HCl (Group RM, n=17) as IVRA. Following the injection, the durations for the initiation of analgesia were recorded. ⋯ Analgesic requirements were similar between the groups (p>0.05). Mild local anesthetic toxicity was observed in Group RM in two patients. We conclude that, when used as IVRA, ropivacaine alone or with tramadol or morphine produced similar analgesia and surgery conditions, and ropivacaine plus morphine had more adverse effects besides its longer duration of analgesia.

Low-back pain is one of the most common causes for seeking professional medical assistance and the most frequent cause of absence from work. It is not rare that the intervertebral discs are the etiological factor. Degenerated discs with internal disruptions may cause axial back pain whereas protrusion or herniation of a disc may result in radicular pain. ⋯ Chemonucleolysis, automated percutaneous lumbar discectomy (APLD), intradiscal laser discectomy, intradiscal electrothermal therapy (IDET) and most recently percutaneous nucleoplasty are the minimally invasive techniques developed for this aim. Percutaneous nucleoplasty is a minimally invasive technique which uses radiofrequency energy to ablate the nucleus pulposus in a controlled manner for disc decompression. The current data about this new technique is insufficient yet, but the preliminary reports indicate that the technique is relatively safe and the outcomes are encouraging.

The perception and interpretation of pain is the end point of an interaction of cognitive, cultural, and environmental factors and this complex interaction effects the pain response and quality of life of each person which shows that pain perception and the verbal and behavioral response shows variations and is specific for each patient. Chronic pain can be due to Fibromyalgia Syndrome (FMS) and Neuropathic Pain (NP) where the underlying pathophysiologic mechanisms are being revealed or it can be chronic low back pain (CLBP) where pain persists in spite of healing of tissue and no underlying pathologic mechanism can be defected. Central sensitization, inhibition of descending pain inhibitory systems, functional changes in autonomic nervous system amd neurotransmitter as well as changes in stress response system are factors contributing to the initiation and maintenance of pain and cognitive, behavioral factors are also important contributors in chronic pain. ⋯ The targets of activity should be physical, functional and social. Psychologic based programs as cognitive-behavioral techniques and operant conditioning are also valid procedures in rehabilitation of chronic pain patients. Rehabilitation should be multidisciplinary and of long-term targeted to valid out-come for success.

Comparative Study
[The comparison of the effects and side effects of local anesthetic and opioid combinations in epidural patient controlled analgesia].
The aim of this study was to retrospectively evaluate the efficacy and side effects of local anesthetic and opioid combinations in 457 patients who have received epidural patient-controlled analgesia (EPCA). Hemodynamic parameters, numeric rating scale, sedation scores, the degree of motor and sensory blockage, the presence of side effects, the parameters of PCA device were recorded from the postoperative pain records. 253 patients received 0.1 % bupivacaine + 3 microg/ml fentanyl (Group B1F3), 80 patients received 0.125 % bupivacaine + 3 microg/ml fentanyl (Group B12F3), 43 patients received 0.125 % bupivacaine + 4 microg/ml fentanyl (Group B12F4), 46 patients received 0.1 % bupivacaine + 0.1 mg/ml morphine (Group B1M1) and 35 patients received 0.125 % bupivacaine + 0.1 mg/ml morphine (Group B12M1). Nausea was significantly higher in group B1M1 compared to B12F3, in group B12M1 compared to B1F3 and B12F3 (p<0.05), vomiting was significantly higher in group B1M1 and B12M1 (p<0.05) compared to B12F3, pruritus was significantly higher in group B12F4 compared to B12F3 and B1F3, in group B1M1 compared to B1F3 and B12F3 and in group B12M1 compared to B1F3 and B12F3 (p<0.05). As a result, in EPCA, the combination of bupivacaine and fentanyl provides as effective analgesia as the combination of bupivacaine and morphine and 3 mg/ml fentanyl admixture may be preferred with less side effects such as nausea, vomiting and pruritus.

Randomized Controlled Trial Clinical Trial
Preemptive oral rofecoxib plus postoperative intraarticular bupivacaine for pain relief after arthroscopic knee surgery.
This study was designed to test the hypothesis whether preemptive administration of rofecoxib, a novel selective COX-2 inhibitor, can prolong intraarticular bupivacaine analgesia after arthroscopic knee surgery. Sixty-two patients were randomly assigned to one of the three groups. Group 1 (n=21) was administered oral rofecoxib 50 mg 1 h before surgery plus intraarticular 0.5 % bupivacaine 20 ml postoperatively. ⋯ Tramadol requirements were significantly less in Group 1 than Group 2 and 3 (4.8 +/- 15.0 mg versus 40.5 +/- 43.6 mg and 67.5 +/- 24.5 mg; p<0.05, p<0.001 respectively), and in Group 2 than Group 3 (p<0.05). There were no significant differences among the groups regarding the tenoxicam requirements and adverse effects. In conclusion, the combination of oral rofecoxib administered preemptively and intraarticular bupivacaine administered postoperatively provided a significant analgesic benefit and decreased the opioid requirements after arthroscopic knee surgery, when compared to bupivacaine alone or saline.
