Background: This double-blind randomized controlled trial (RCT) was conducted to evaluate the pre-emptive analgesia and anti-inflammatory efficacy of piroxicam compared with tramadol in patients undergoing oral surgery. Methods: Seventy-eight patients who required extraction of impacted mandibular third molars were randomized into three treatment groups of 26 patients each: group I received 100 mg of tramadol, group II received 20 mg of piroxicam, and group III received a placebo. Drugs were administered intramuscularly 30 min prior to the extraction procedure. Results: Pain intensity, time to first analgesic administration, total analgesic consumption, facial edema, and trismus were the outcomes of interest. The group receiving 20 mg of piroxicam showed significantly lower pain intensity, increased time to first analgesic, and reduced edema from preoperative to postoperative day seven than those in the tramadol and placebo groups. Conclusion: The findings of this study showed that piroxicam had significant pain relief efficacy after third molar surgery compared with that in tramadol.

Background: Some clinical trials have reported that a new analgesic combination of tramadol and acetaminophen provides good efficacy in various pain models. For the more clinical uses of this agent, comparisons about the onset of analgesia and analgesic efficacy in the acute state of pain with the other drugs known as strong analgesics were needed. Purpose: The goal of this study was to compare the times to onset of analgesia and the other analgesic efficacy of 75 mg tramadol/650 mg acetaminophen and 20 mg codeine/500 mg acetaminophen/400 mg ibuprofen in the treatment of acute pain after oral surgery. Patients and Methods: Using a randomized, single-dose, parallel-group, single-center, and active-controlled test design, this clinical study compared the times to onset of analgesia using a two-stopwatch technique and the other analgesic efficacy of the single-dose tramadol/acetaminophen and codeine/acetaminophen/ibuprofen. These were assessed in 128 healthy subjects with pain from oral surgical procedures involving extraction of one or more impacted third molars requiring bone removal. From the time of pain development, the times to onset of perceptible and meaningful pain relief, pain intensity, pain relief, an overall assessment, and adverse events of the study medications were recorded for 6 hours. Results: The demographic distribution and baseline pain data in the two groups were statistically similar. The median times to onset of perceptible pain relief were 21.0 and 24.4 minutes in the tramadol/acetaminophen and codeine/acetaminophen/ibuprofen groups respectively and those to onset of meaningful pain relief were 56.4 and 57.3 minutes, which were statistically similar. The other efficacy variables such as mean total pain relief (TOTPAR) and the sum of pain intensity differences (SPID) were also similar in the early period after pain development and drug dosing. The safety of tramadol/acetaminophen was well tolerated and very comparable to that of codeine/acetaminophen/ibuprofen. Conclusions: In this acute dental pain model, the onset of analgesia and analgesic efficacy of tramadol/acetaminophen was comparable to that of codeine/acetaminophen/ibuprofen. These results showed that tramadol/acetaminophen was recommendable for fast and effective treatment in the management of postoperative acute pain.

Background: Transforaminal epidural steroid injections are known to reduce inflammation by inhibiting synthesis of various proinflammatory mediators and have been used increasingly. The anti-inflammatory properties of opioids are not as fully understood but apparently involve antagonism sensory neuron excitability and pro-inflammatory neuropeptide release. To date, no studies have addressed the efficacy of transforaminal epidural morphine in patients with radicular pain, and none have directly compared morphine with a tramadol for this indication. The aim of this study was to compare morphine and tramadol analgesia when administered via epidural injection to patients with lumbar radicular pain. Methods: A total of 59 patients were randomly allocated to 1 of 2 treatment groups and followed for 3 months after procedure. Each patient was subjected to C-arm guided transforaminal epidural injection (TFEI) of an affected nerve root. As assigned, patients received either morphine sulfate (2.5 mg/2.5 ml) or tramadol (25 mg/0.5 ml) in combination with 0.2% ropivacaine (1 ml). Using numeric rating scale was subsequently rates at 2 weeks and 3 months following injection for comparison with baseline. Results: Both groups had significantly lower mean pain scores at 2 weeks and at 3 months after treatment, but outcomes did not differ significantly between groups. Conclusions: TFEI of an opioid plus local anesthetic proved effective in treating radicular pain. Although morphine surpassed tramadol in pain relief scores, the difference was not statistically significant.

Background: The effect of dexmedetomidine as an adjuvant in the adductor canal block (ACB) and sciatic popliteal block (SPB) on the postoperative tramadol-sparing effect following spinal anesthesia has not been evaluated. Methods: In this randomized, placebo-controlled study, ninety patients undergoing below knee trauma surgery were randomized to either the control group, using ropivacaine in the ACB + SPB; the block Dex group, using dexmedetomidine + ropivacaine in the ACB + SPB; or the systemic Dex group, using ropivacaine in the ACB + SPB + intravenous dexmedetomidine. The primary outcome was a comparison of postoperative cumulative tramadol patient-controlled analgesia (PCA) consumption at 48 hours. Secondary outcomes included time to first PCA bolus, pain score, neurological assessment, sedation score, and adverse effects at 0, 5, 10, 15, and 60 minutes, as well as 4, 6, 12, 18, 24, 30, 36, 42, and 48 hours after the block. Results: The mean ± standard deviation of cumulative tramadol consumption at 48 hours was 64.83 ± 51.17 mg in the control group and 41.33 ± 38.57 mg in the block Dex group (P = 0.008), using Mann-Whitney U-test. Time to first tramadol PCA bolus was earlier in the control group versus the block Dex group (P = 0.04). Other secondary outcomes were comparable. Conclusions: Postoperative tramadol consumption was reduced at 48 hours in patients receiving perineural or systemic dexmedetomidine with ACB and SPB in below knee trauma surgery.

Tramadol is an opioid analgesic agent that has been the subject of a series of case reports suggesting potential for misuse or abuse. However, it is not a controlled substance and is not generally considered addictive in Korea. In this study, we examined the dependence potential and abuse liability of tramadol as well as its effect on the dopaminergic and serotonergic systems in rodents. In animal behavioral tests, tramadol did not show any positive effects on the experimental animals in climbing, jumping, and head twitch tests. However, in the conditioned place preference and self-administration tests, the experimental animals showed significant positive responses. Taken together, tramadol affected the neurological systems related to abuse liability and has the potential to lead psychological dependence.

Background: The aim of this study was to compare the local anesthetic effect of tramadol with that of lignocaine in the extraction of immobile (grade 0) maxillary first molars. Methods: This was a randomized, double-blind, equally balanced, controlled trial conducted on a sample population of 116 patients. The patients were randomly divided into two groups: group A (control) and group B (study). Group A and group B participants received 1.8 ml of 2% lignocaine without adrenaline and 1.8 ml of 5% tramadol, respectively through the supra-periosteal infiltration technique before extraction. Intraoperative pain was recorded on the Visual Analog Scale (VAS) and was evaluated using two unpaired t-tests. Results: Intraoperative pain was evaluated in both the control and study groups. In the control group, the mean VAS score was 0.71 ± 0.81, while in the study group, the mean intraoperative VAS score was 1.21 ± 0.86, with the difference between the two mean values being statistically significant (P = 0.001). Conclusion: Tramadol has a less potent local anesthetic effect than lignocaine. As a higher dose of tramadol is required to obtain the desired anesthetic effect, it should be used as a supplement to lignocaine in extensive surgical procedures. It can also be used in patients allergic to lignocaine.

8개월령, 수컷 진도개가 오른쪽 후지 파행으로 의뢰되었다. 이 개는 방사선 검사를 통하여 오른쪽 대퇴골의 단순 골절로 진단되었다. 대퇴골절의 수술적 교정 이후, 술 후 진통제로 합성 아편계 유사 약물인 트라마돌이 정맥 내 주사로 투여되었다. 트라마돌의 투여 직후 발작이 시작되었다. 집중적인 환자 관리에도 불구하고 투여 약 17시간 후 이 개는 폐사하였다. 폐사를 하게 된 원인과 관련하여 트라마돌의 투여에 의한 발작이 연관되어 있을 것으로 추측할 수 있었다. 부검을 실시한 결과 조직병리학적 분석에 따라 본 환자는 괴사성 수막뇌염(NME)으로 진단되었다. 괴사성 수막뇌염을 가진 개에서 트라마돌의 투여가 폐사를 일으킨 발작의 유발과 관련되어 있을 것으로 생각되었다. 본 증례를 통해 트라마돌이 통증 관리에 있어 안전하고 효과적인 약물로 알려져 있으나 뇌염, 뇌수두증, 뇌병증 등의 신경계질환이 있는 환자에서는 주의 깊게 사용되어야 한다는 것을 알 수 있었다.

Background: Immune responses appear to be affected by anesthetics and analgesics. We investigated the effects of caudal tramadol on the postoperative immune response and pain management in pediatric patients. Methods: Sixty ASA-I pediatric patients aged 3-10 years undergoing lower abdominal surgery. Patients were randomly assigned either to a caudal bupivacaine (0.25%) group (group B), or a group that received caudal tramadol (1 mg/kg) added to the bupivacaine (0.25%) (group T). Both were diluted in a 0.9% NaCl solution to a total volume of 1ml/ kg. The systemic immune response was measured by collecting blood samples preoperatively, at the end of anesthesia, and at 24 and 72 hours postoperatively, and studied for interleukin IL-6, C-reactive proteins (CRP) cortisol levels, and leucocytes with its differential count. Postoperative pain was assessed along with sedation scales. Results: Postoperative production of IL-6 was significantly higher in group B at the end of anesthesia, than at the $24^{th}$ hour, and at the $72^{nd}$ hour in group B and group T, respectively. The immune response showed leukocytosis with increased percentages of neutrophil and monocytes, and a decreased lymphocyte response rate within both groups with no significant differences between the groups. Cortisol and CRP were significantly higher in group B. Conclusions: Adding tramadol to a caudal bupivacaine block can attenuate the pro-inflammatory cytokine response, Cortisol, and CRP in children undergoing lower abdominal surgery.
