The purpose of this study is to determine the frequency and variety of strategies being used in the Emergency Department (ED) management of sickle cell pain crisis (SCPC). One thousand randomly selected academic emergency physicians received a multiple-choice survey; 549 (55%) completed the survey. Forty-five percent of respondents treat patients with SCPC every week or almost every shift. Twenty percent use protocols for management of SCPC. Respondents consider pain refractory to outpatient treatment if it is persistent after two (23%) or three (53%) doses of parenteral analgesic. Meperidine or morphine is the most common initial analgesic. In the routine management of uncomplicated SCPC, i.v. analgesics, i.v. hydration, oxygen therapy, and complete blood counts are often or always used by 67, 71, 66, and 82% of respondents, respectively. Some patterns in the diagnostic and therapeutic management of patients with SCPC in the ED are identified, but overall practice is highly variable. Some popular elements of care are divergent from those suggested by the scientific literature.

A 65-year-old man with adult polycystic kidney disease (APKD) and chronic renal failure suffered from intractable abdominal pain and distension for 2 weeks. Meperidine infusion did not alleviate his pain. However, pain and abdominal distension were successfully controlled by embolization of both renal arteries.

The Agency for Health Care Policy and Research (AHCPR) established guidelines for the use of meperidine (demerol), a common inpatient analgesic. These guidelines define standards of care for acute and chronic cancer pain management and address many of the problems with meperidine and its metabolite, normeperidine. The purpose of this study was to determine whether meperidine was prescribed in compliance with AHCPR guidelines, whether patients exhibited any adverse reactions to meperidine, and to determine the analgesic efficacy of meperidine. Three hundred inpatient charts were reviewed and identified meperidine as the primary analgesic in 157 nonobstetric inpatients. Age, sex, weight, dosing interval, route of administration, duration of meperidine use, serum chemistry values, primary diagnosis, associated medical conditions, and medications concurrently being taken with meperidine were the parameters analyzed. An interview was conducted to ascertain medical and drug history, chronicity of pain syndromes, analgesic drug history, and analgesic efficacy. A visual analog scale for pain (range = 0 to 10) and an analgesic satisfaction survey (range = 1 to 5) were used. Of 157 patients, 124 (79.8%) were in conflict with AHCPR guidelines. The most frequent conflict was found to be suboptimal dosing regimen and treatment of chronic pain. Often concurrent analgesics were given with the meperidine to achieve adequate analgesia. Higher analgesic satisfaction scores were noted when meperidine was given with concurrent analgesics. Meperidine also was administered to patients in renal failure or with medications contraindicated with meperidine use. No significant adverse effects were noted with meperidine use in this sample population other than an increased incidence of confusion in the elderly population.

Meperidine was the first synthetic opioid agent. It acts mainly as an antagonist of mu (#m) receptors and has an analgesic potency ten times greater than that of morphine. Like other opioid drugs, meperidine causes nausea, vomiting, urinary retention and respiratory depression; a point of difference, however, is that it acts on nerve fibers and has properties similar to those of local anesthetics. It has therefore been used as an alternative to other opioids for anesthetic blockade. We review the indications and contraindications of meperidine administered by different routes. For pain, epidural administration has proven to be a good alternative to intravenous administration and epidural meperidine has been combined with local anesthetics using lower doses of both drugs and producing fewer side effects. Intradural meperidine has been used as the sole anesthetic agent in various types of surgery, its principal advantage being that it provides long-lasting postoperative analgesia. Spinal meperidine has the advantage over morphine of a lower incidence of respiratory depression, particularly late-occurring depression. An intravenous route has been used for treating moderate to severe pain, for regional anesthesia, for premedication and for analgesia during anesthesia. Meperidine's action on kappa receptors has meant that it is considered the most effective drug for treating postanesthetic trembling. Although meperidine has been used effectively to treat non-surgical pain, mainly from colic, this review focuses on its usefulness in the perioperative period.

Thirty bitches undergoing routine neutering were used in an assessor-blinded trial of the postoperative analgesic effects of pethidine and carprofen administered either together or singly. The level of analgesia was assessed by visual analogue scale (VAS) scores for pain and sedation and by nociceptive mechanical threshold testing. The two drugs administered together, and carprofen alone, provided good postoperative analgesia as assessed by VAS scoring. Pethidine alone did not provide postoperative analgesia of sufficient duration.

The need for analgesia to overcome pain in labour is highly requested by women today. Various ways either non pharmachologic e.g. Emotional sustain, psycho-prophylactic preparation, yoga and hypnosis or pharmachologic such as epidural blockade or parenteral are used. Therefore in our study we evaluated the efficacy and tolerability of the two opioids usually used today in parenteral analgesia to reduce pain during labour: Tramadol and Meperidine. We studied two groups of patients each made up of 20 women in labour, all at term and with a physiologic course of pregnancy. 75 mg i.m. of Meperidine chloryhydrate were somministered in the first group while in the second group 100 mg i.m. of tramadol chloryhydrate were somministered. Various maternal, fetal and neonatal parameters were then monitored demonstrating--A moderate maternal analgesic effect in both drugs (evaluated through the analogic grading of pain). In the group to whom Meperidine was given, sedative effects on the mother were observed associated with respiratory depression in the newborn (the latter evaluated through the Apgar index at 1st and 5th minute of life and pH of the blood obtained at the umbilical cord. The data obtained permitted us to conclude that Tramadol in accordance to the obtained in literature gives an analogous analgesic effect, with better tolerability for the absence of collateral effects on the mother, fetus and newborn.

Mechanical nociceptive thresholds are regularly used to determine the efficacy of analgesic agents both experimentally and clinically in a variety of species. The 'pressure of palpation device' (PPD) was developed for use in cats and is a small battery operated device with a finger-mounted force sensing resistor (FSR, Interlink Electronics, Northumberland. UK). The PPD was used in a study assessing the analgesic efficacy of pethidine after castration in cats. Pethidine was demonstrated to prevent the development of post-operative scrotal hypersensitivity for up to 2 hours after castration, whereas cats given no analgesics showed marked hyperalgesia immediately after surgery. Visual Analogue Scale (VAS) pain scores after castration showed a similar analgesic effect of pethidine. These results suggest that the PPD could become a useful research tool to assess the effectiveness of analgesic agents in the cat.

Evaluation of the modified "postanaesthesiological questionnaire" pointed to a subtle influencing of the condition of patients who had undergone 3rd molar surgery in general anaesthesia by using different premedication variants: "Atropine, Pethidine and Midazolam" (group A) and "Atropine, Midazolam and S-Ketamin" (group B). The combination in group B seems to be more suitable. On the one hand, a lower incidence of unwanted side-effects was found and, on the other hand, remarkable positive effects were observed. Of particular significance with this combination was also the more effective suppression of postoperative pain. The Propofol-supplemented general anaesthesia prepared in this way and administered using a nasal intubation technique found the full approval of the patients. Postoperative pain therapy was effective and also inexpensive, costing just 8.20 DM per patient, according to current prices calculated by Magdeburg University Hospital.

Morphine is the preferred analgesic agent for the critically ill patient. Fentanyl is the preferred analgesic agent for critically ill patients with hemodynamic instability or for patients manifesting symptoms of histamine release with morphine or morphine allergy. Hydromorphone is an acceptable alternative to morphine for patients with significant adverse affects from morphine or severe renal dysfunction. Meperidine and intravenous codeine should be avoided if at all possible. APAP and NSAIDs may be useful in the management of acute pain secondary to their opioid-sparing effects. Use of nonopioid analgesics may reduce the dose of opioid required for adequate pain control and help to minimize opioid-induced side effects. NSAIDs should be used only when the benefit-to-risk ratio is favorable. APAP should be used as an adjunct but not as the sole analgesic agent in critically ill patients. Regardless of which agent or agents are used to optimize pain control, it is imperative that caregivers recognize that the optimal analgesic dose and regimen vary widely between patients. Based on the pharmacokinetics and pharmacodynamics of the agent(s) selected, enough time for an adequate trial should be allowed before switching to other agents. Employing these principles optimizes the use of medications in the management of the complex physiologic response to pain.

Parenteral opioids are commonly used for labor pain relief and have been the subject of research for many years. The objectives of this review were to determine the safety and effectiveness of parenteral opioids in this context. Of 85 trials systematically reviewed, 48 comprising more than 9800 were included, but the number of trials contributing data to individual outcome measures is very limited. Epidural provides better pain relief. However, if women opt for systemic analgesia, no strong preference for any of the opioids can be recommended. Pethidine is the most commonly used opioid worldwide, and although there are considerable doubts about its analgesic effectiveness and concerns about its potential maternal, fetal, and neonatal side effects, it has the virtue of familiarity and low cost. There is as yet no convincing research evidence to show that alternative opioids are better. In view of the large number of women who receive opioids in labor and the paucity of research evidence about the relative effectiveness and side effects of different opioids and opioids compared with other methods (apart from epidural), well-designed and suitably sized trials of pethidine versus the main alternatives that address substantive outcomes for mothers and babies are strongly recommended.
