Tramadol, a centrally acting analgesic, consists of two enantiomers, both of which contribute to analgesic activity via different mechanisms. (+) Tramadol and the metabolite (+) -O- desmethyl-tramadol (M1) are agonists of the mu opioid receptor. (+) Tramadol also stimulates presinaptic release of serotonin and inhibits serotonin reuptake whereas (-) tramadol inhibits norepinephrine reuptake. Thus tramadol enhances inhibitory effects on pain transmission both by opioid and monoaminergic mechanisms. The complementary and synergistic actions of the two enantiomers improve the analgesic efficacy and tolerability profile of the racemate. ⋯ Although trials in literature demonstrate immune-stimulating effects of tramadol, there are also trials suggesting immunesuppressive effects that are lesser than morphine. Owing to its pharmacological properties, tramadol is more appropriate than NSAIDs for patients suffering from gastrointestinal and renal problems. Besides its proven clinical efficacy tramadol is a safe drug as respiratory depression, cardiovascular side effects, drug abuse and dependence are of minor clinical relevance, unlike some other opioids.

Randomized Controlled Trial
[Addition of ketamine infusion to patient controlled analgesia with intravenous morphine after abdominal hysterectomy].
In our study we aimed to reduce postoperative morphine consumption, prevent adverse effects of morphine, and improve analgesic quality via adding analgesic doses of ketamine infusion to intravenous morphine-patient controlled analgesia (PCA). After local ethics committee approval, 45 patients scheduled for total abdominal hysterectomy were included in the study. In the postoperative period the patients were separated into two groups randomly. ⋯ When adverse effects were evaluated we found that nausea was higher in Group S (p<0.05), while there was no difference in the other side effects (p>0.05). Patient satisfaction was better in the 24th and 48th hours in Group K and was found to be statistically significant (p<0.05). Our results suggest that ketamine infusion added to opioids for postoperative analgesia, reduces total opioid requirement and prevents side effects.

Randomized Controlled Trial
[Spinal anesthesia in cesarean section with different combinations of bupivacaine and fentanyl].
The use of opioids for spinal anesthesia increases the anesthetic quality, reduces side effects and also has advantages for the postoperative analgesia. The aim of this study was to evaluate the effects of subarachnoid %0.5 hyperbaric bupivacaine (B) alone or combined with 10 or 20 mg fentanyl (F) on the anesthetic properties for cesarean section and newborn. 45 patients were randomized to three groups to receive 1.8 ml anesthetic drug for spinal anesthesia. ⋯ The onset of sensory blok at T4 level, maximum anesthetic level and the onset time, the level of the motor block, duration of effective analgesia, use of total i.v. fluids and ephedrine, relaxation at the operative area, side effects, umblical cord blood gases, Apgar and neurological and adaptive capacity scores of the newborn were compared among the groups. We conclude that compared to control group, the addition of fentanyl to hyperbaric bupivacaine leads to a decrease in local anesthetic doses and so to a decrease in the incidence of side effects and postoperative analgesic consumption. 7 mg B+20 mg F seems to be the preferable combination for that reasons.

The most important complication of lumber disc hernia operations is Failed Back Surgery Syndrome (FBSS), which goes with fibrotic adhesions at the surgical site. The primary treatment applied to the cases that develop FBSS is the placement of Racz catheter under floroscopy and application of epidural neuroplasty which is a three-day procedure. However, this intervention, from which patients benefit a great deal, has some important complications during and after the application. ⋯ Monthly follow-ups for 12 month were proposed to the patient, while surgery was not recommended. At the end of this period, no sign of infection was observed and neurologic and radiologic findings of the patient did not worsen. It is also interesting that a remarkable recovery was observed in the patient's clinical situation.

This definitive study has been performed to assess the approach to pain relief in emergency trauma units. The study population consisted of patients seen at the emergency trauma clinics of three different, state-owned, research hospitals in the city of Istanbul. A total of 375 patients with an age range of 18-65 were included. ⋯ Of the patients enrolled in the study, only 17.1% (64 patients) had received analgesics. The most common analgesic medication group used was Nonsteroid Anti Inflammatory Drugs (NSAID). According to these results, 82.9% of patients with pain due to trauma had not received analgesics and it can be concluded that pain in trauma patients is undertreated.
