Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of bupivacaine-fentanyl versus bupivacaine-morphine for patient controlled epidural analgesia].
Analgesic efficacy and possible side effects of bupivacaine-fentanyl (BF) and bupivacaine-morphine (BM) combinations for patient controlled epidural analgesia (PCEA) have been compared. Sixty ASA I-II patients who had PCEA following lower abdominal surgery were admitted to the study. Epidural catheter was inserted at the level of L3-4 or L4-5 following induction of general anesthesia. ⋯ One patient in Group BF had unilateral motor block, one patient in Group BM had respiratory depression responding to i.v. naloxon administration. The incidence of pruritus was higher in Group BM than Group BF (p<0.05). Both treatment modalities provided adequate postoperative analgesia, but the risk of respiratory depression with opioid use should be considered.

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 Comparative Study Clinical Trial
Cryo/Cuff compared to epidural anesthesia after knee unicompartmental arthroplasty: a prospective, randomized and controlled study of 60 patients with a 6-week follow-up.
The aim of this prospective, randomized, and controlled study was to evaluate the efficacy of cold compressive dressings (Cryo/Cuff) and epidural anesthesia (EDA) in the postoperative management of primary unicondylar knee arthroplasty. Sixty patients (61 knees) were randomized into 3 groups. ⋯ There was no significant difference in morphine consumption between the 2 treatment groups. Based on the results of this study, Cryo/Cuff seems to be a rational, effective, risk-free, and well-tolerated alternative to EDA to reduce pain and morphine after unicondylar knee arthroplasty.

Randomized Controlled Trial Clinical Trial
Efficacy and safety of single and repeated administration of 1 gram intravenous acetaminophen injection (paracetamol) for pain management after major orthopedic surgery.
Intravenous acetaminophen injection (paracetamol) is marketed in Europe for the management of acute pain. A repeated-dose, randomized, double-blind, placebo-controlled, three-parallel group study was performed to evaluate the analgesic efficacy and safety of intravenous acetaminophen as compared with its prodrug (propacetamol) and placebo. Propacetamol has been available in many European countries for more than 20 yr. ⋯ Intravenous acetaminophen, 1 g, administered over a 24-h period in patients with moderate to severe pain after orthopedic surgery provided rapid and effective analgesia and was well tolerated.

Randomized Controlled Trial Clinical TrialEvaluation of the optimal preemptive dose of gabapentin for postoperative pain relief after lumbar diskectomy: a randomized, double-blind, placebo-controlled study.
We evaluated the optimal preemptive dose of gabapentin for postoperative pain relief after single-level lumbar diskectomy and its effect on fentanyl consumption during the initial 24 hours in a randomized, double-blinded, placebo-controlled study in 100 patients with American Society of Anesthesiologists physical status I and II. Patients were divided into five groups to receive placebo or gabapentin 300, 600, 900, or 1200 mg 2 hours before surgery. After surgery, patients were transferred to the postanesthesia care unit (PACU). ⋯ Patients who received gabapentin 600, 900, and 1200 mg had lower VAS scores at all time points than patients who received gabapentin 300 mg (P < 0.05). Increasing the dose of gabapentin from 600 to 1200 mg did not decrease the VAS score, nor did the increasing dose of gabapentin significantly decrease fentanyl consumption (702.5, 635, and 626.5 microg). Thus, gabapentin 600 mg is the optimal dose for postoperative pain relief following lumbar diskectomy.
