Prickly pear(Opuntia ficus-indica var. saboten Makino, Cactaceae) is a tropical or subtropical plant, which is widely used as folk medicine for burned wound, edema and indigestion. Screening on the biological properties of the fruits(OFS-Fr) and stems(OFS-St) of the plant was carried out to prove the pharmacological significance. By hot plate and acetic acid-inducing writhing methods, significant analgesic effects of OFS-Fr and OFS-St were found in mice and anti-edemic effect was observed in carrageenin-induced inflammatory rats. However, the extracts showed no significant actions on central and autonomic nervous system and blood circulatory system, which imply no toxic effects to animal.

Background: Hydromorphone has an intermediate lipid solubility range that falls between morphine and fentanyl. Lipophilic activity during opioid epidural administration is important in relation to both the side effects and analgesic efficacy. The purpose of this study was to compare epidural hydromorphone and fentanyl when concomitantly infused with bupivacaine in patients undergoing a thoracotomy. Methods: Seventy-seven thoracotomy patients, with patient-controlled epidural analgesia (PCEA), were blindly allocated into two groups [group F (n = 34); 0.1% bupivacaine and fentanyl $5{\mu}g/ml$, group H (n = 34); 0.1% bupivacaine and hydromorphone $16{\mu}g/ml$)]. The basal PCEA rate and demand dose were 4 ml/hr and 3 ml, respectively. The visual analogue scale (VAS) for pain, and pruritus, sedation and nausea were measured at 6, 12 and 24 hours after the operation. Results: There were no significant differences in the VAS pain scores and the incidences of pruritus, nausea and sedation between the two groups. The total infused volume after 24 hours was lower in H compared to that of F group (P < 0.05). Conclusions: We conclude that epidural hydromorphone or fentanyl administration has a similar analgesic efficacy and shows similar incidences of side effects, when concomitantly infused with bupivacaine, in the management of acute pain following a thoracotomy.

Reiestad and Stromskag recently introduced the interpleural installation of local anesthetic solutions as a technique for the management of postoperative pain in patients undergoing cholecystectomy, renal surgery, and breast surgery. This study was done to manage postoperative pain in the patients undergoing unilateral upper-abdominal surgery and thoracotomy. Twenty patients received 0.5% bupivacaine 20 ml with epinephrine (Children, received 10 ml). Results were as follows: 1) Analgesic effects appeared in 15.56 minutes; mean analgesic duration from the initial intrapleural injection was 10.5 hours. 2) Blood pressure increased more after the operation than before the operation. Blood pressure before injection of bupivacaine was highest (p<0.01). Heart rate was increased before injection and 10 minutes after injection of 0.5% bupivacaine (p<0.05). 3) The values of $PaCO_2$, were improved from $41.7{\pm}2.02\;mmHg$ ($PaCO_2$), $85.2{\pm}2.41\;mmHg$ ($PaO_2$) to $37.8{\pm}2.41\;mmHg$ ($PaCO_2$), $107.0{\pm}7.86\;mmHg$ ($PaO_2$) respectively (p<0.01). 4) Complication such as pneumothorax, atelectasis and CNS toxicity did not appear. 5) Intrapleural administration of local anesthetics after unilateral upper-abdominal and thoracic surgery provided a satisfactory pain control.

In this study, we evaluated the anti-nociceptive activities of Sorbus alnifolia. To investigate the anti-nociceptive properties of the methanolic extract of Sorbus alnifolia (MSA), we conducted several tests using various experimental mouse pain models. Herein, MSA significantly delayed the latency time and writhing motion in the hotplate test and acetic acid test, respectively. These result indicated that MSA has an ability to manage both peripheral and central nociception. We could further confirm the analgesic effects of MSA by performing formalin test. In combination test using naloxone, a non-selective opioid receptor antagonist, analgesic activity of MSA was partly antagonized by naloxone, but not completely, indicating that the MSA acts as a partial opioid receptor agonist. Out results suggest that the S. alnifolia may be possibly used as valuable anti-nociceptive agent.

Postoperative pain following tonsillectomy remains a significant obstacle to speedy recovery and smooth convalescence. Inadequate analgesia causes poor oral intake and influences the length of hospital stay and ability to return to normal activity. Patient Controlled Analgesia (PCA) is a method of analgesia adminstration that consists of a computer driven pump with a button that the patient may press to adminster a small dose of analgesic drug. The aim of this study was to examine whether Intravenous Patient Controlled Analgesia (IV-PCA) can reduce postoperative pain after tonsillectomy. The 100 patients undergoing tonsillectomy with general anesthesia were divided into two groups. The PCA group patients (n=80) received a mixture of nalbuphine and ketorolac by Walkmed PCA infusor during first 48 postoperative hours. In control group (n=20), the patients received oral acetoaminophen (Tyrenol) regularly and tiaprofenic acid (Surgam) intramuscularly on a p.r.n basis. Analgesic efficacy was evaluated with visual linear analogue scale (VAS) and the adverse effects were evaluated with 4 point scale. The patients of PCA group had less pain than those of control group. The adverse effects in the PCA group were nausea and vomiting. This study suggests that IV-PCA may be safe and effective method of pain control after adult tonsillectomy and is better accepted than oral or intramuscular pain medications.

Intracerebroventricular (ICV) infusion of morphine (MOR) produces strong analgesia in man and animals. The analgesic effect is thought to be mediated by the centrifugal inhibitory control. But neural mechanisms of the analgesic effect of ICV morphine are not well understood. In the present study, we found that ICV MOR had dual actions on the activity of dorsal horn heurons: it produced both inhibition and excitation of dorsal horn neurons. Since MOR exerts its action via three different types of opioid receptors, we further sought to investigate if there are differential effects of opioid receptor agonists on dorsal horn neurons when administered intracerebroventricularly. Effects of ICV MOR were tested in 28 dorsal horn neurons of the spinal cord in the cat. ICV MOR inhibited, excited and did not affect the heat responses of dorsal horn neurons. ICV DAMGO and DADLE, $\mu$- and $\delta$-opioid agonist, respectively, exhibited the excitation of dorsal horn neurons. In contract, U-50488, a k-opioid agonist, exhibited both the inhibition and excitation of dorsal horn neurons. These results suggest that opioid receptors have different actions on activity of dorsal horn neuron and that the inhibitory action of k-opioid agonist may subserve the analgesia often produced by ICV MOR.

Background: Spinal opioid administration is an excellent option to separate the desirable analgesic effects of opioids from their expected dose-limiting side effects to improve postoperative analgesia. Therefore, physicians must better identify either specific opioids or adequate doses and routes of administration that result in a mainly spinal site of action rather than a cerebral analgesic one. Methods: The purpose of this topical review is to describe current available clinical evidence to determine what opioids reach high enough concentrations to produce spinally selective analgesia when given by epidural or intrathecal routes and also to make recommendations regarding their rational and safety use for the best management of postoperative pain. To this end, a search of Medline/Embase was conducted to identify all articles published up to December 2013 on this topic. Results: Recent advances in spinal opioid bioavailability, based on both animals and humans trials support the theory that spinal opioid bioavailability is inversely proportional to the drug lipid solubility, which is higher in hydrophilic opioids like morphine, diamorphine and hydromorphone than lipophilic ones like alfentanil, fentanyl and sufentanil. Conclusions: Results obtained from meta-analyses of RTCs is considered to be the 'highest' level and support their use. However, it's a fact that meta-analyses based on studies about treatment of postoperative pain should explore clinical surgery heterogeneity to improve patient's outcome. This observation forces physicians to use of a specific procedure surgical-based practical guideline. A vigilance protocol is also needed to achieve a good postoperative analgesia in terms of efficacy and security.

Angelicas Tenuissimae Radix (ATR) has traditionally been used for flu-like symptoms, limb-ache and disability, and even for toothache. In the present study, the effect of ATR on carrageenan-induced edema, acetic acid-induced abdominal pain, and heat-induced hyperalgesia were investigated using rats and mice. In the present results, ATR reduced carrageenan-induced edema in rats and inhibited acetic acid-induced abdominal pain in mice. Here in this study, we have shown that ATR possesses anti-inflammatory and analgesic effects.
