Randomized Controlled Trial Comparative Study Clinical TrialEffect of clonidine on postpartum shivering after epidural analgesia: a randomized, controlled, double-blind study.
In obstetric patients treated with epidural analgesia during labor and delivery, shivering is quite frequent due to stress, vasodilatation, infusion of fluids, low ambient temperature, and the direct effect of solution injected into the epidural space. Sixty obstetric patients who developed shivering after receiving epidural analgesia for delivery were randomly assigned to treatment with clonidine 0.150 mg i.v. (N = 20), meperidine 50 mg i.v. (N = 20), or saline solution (N = 20). Drug administration was double blind. ⋯ Clonidine was as effective as meperidine in controlling shivering and caused a greater reduction in heart rate. Drowsiness occurred after clonidine as well as meperidine. Thus, clonidine proved to be effective in controlling shivering and adrenergic response after delivery using epidural analgesia and produced an acceptable level of drowsiness.

The stability of mixtures of morphine hydrochloride, bupivacaine hydrochloride, and clonidine hydrochloride in portable pump reservoirs for the management of chronic pain syndromes.
The physical and chemical stability of a combination of drugs commonly administered into the epidural or intrathecal space for the treatment of chronic pain was investigated. The concentrations of bupivacaine hydrochloride, morphine hydrochloride, and clonidine hydrochloride were measured using high performance liquid chromatography. The solutions were stored in reservoir bags for up to 90 days. ⋯ A small increase in concentration of all three drugs did occur over time, most probably due to evaporation processes. In conclusion, no problems in physical or chemical stability are to be expected when combining morphine, bupivacaine, and/or clonidine for long-term epidural or intrathecal administration. In the case of clinically apparent loss of analgesic efficacy, other mechanisms should be considered.

Randomized Controlled Trial Clinical TrialTrial of a topically administered local anesthetic (EMLA cream) for pain relief during central venous port accesses in children with cancer.
Procedure-related pain is a significant problem for many children receiving cytotoxic chemotherapy. In an effort to lessen this toxicity, we studied the efficacy and safety of administering topical local anesthesia using EMLA cream in 47 evaluable children with cancer undergoing implanted central venous port injections. Children (< 21 years old) scheduled to undergo repeated venous access procedures were selected for study. ⋯ Statistically significant decreases in pain intensity scores (P < 0.002) were recorded by both children and investigators during the use of EMLA cream as compared with placebo. There was a good correlation between pain scores recorded by both patients and health care providers using both visual analog scales and categorized pain measurement tools. The topical application of EMLA cream 5% provides highly effective superficial anesthesia, and promises to be extremely useful for pain relief during percutaneous access procedures in cancer patients.

Cost issues related to pain management: report from the Cancer Pain Panel of the Agency for Health Care Policy and Research.
The clinical problem of unrelieved pain has received much attention over the previous decade with a major focus on cancer pain and acute postoperative pain. Organizations such as the World Health Organization (WHO), the National Cancer Institute, the American Pain Society (APS), and others have addressed the previously neglected areas of pain assessment, pharmacologic treatment, and the knowledge and attitudes of health-care providers. ⋯ This 13-point framework is an attempt to isolate specific cost issues, identify what is known in these areas, and address implications for future research. A brief synopsis of these 13 areas of cost analysis is provided including comments regarding work in progress by the panel and directions for future health-policy research related to pain management.

Case ReportsIntrathecal morphine and bupivacaine in advanced cancer pain patients implanted at home.
Fifteen patients with pain due to advanced cancer who no longer obtained relief from conventional treatment using oral or parenteral opioids were administered morphine and bupivacaine by continuous intrathecal infusion. Thirteen patients were implanted at home due to poor medical condition or refusal to be hospitalized. ⋯ Only minor side effects were evidenced. Implantation at home of an intrathecal catheter to administer morphine and bupivacaine provided a degree of pain relief during the last days of life that would have otherwise been impossible and did so without producing important complications.
