Randomized Controlled Trial Clinical Trial
Walking with labor epidural analgesia: the impact of bupivacaine concentration and a lidocaine-epinephrine test dose.
Regional analgesia techniques for labor that permit ambulation are popular among parturients. This study evaluated the influence of bupivacaine bolus concentration and a 3-ml 1.5% lidocaine-epinephrine test dose, on analgesic effectiveness and the ability to walk after block placement. ⋯ Omitting a lidocaine-epinephrine test dose and using 0.125% bupivacaine for the initial bolus should permit ambulation in the early postblock period for most parturients who elect this option.

Comparative StudyA comparison between the effectiveness of epidural analgesia and parenteral pethidine during labor.
The study was aimed to define parturients' opinion on either epidural analgesia or intravenous pethidine, and to determine the effect of both analgesics after delivery. We interviewed and examined 401 consecutive parturients who requested analgesia during the beginning of their active stage of labor. Of those, 131 women requested and underwent epidural analgesia, and 270 received parenteral pethidine. ⋯ We conclude that epidural analgesia is more effective than parenteral analgesia in pain and discomfort relief. This method is helpful also the day after delivery. Thus, epidural analgesia should be strongly recommended to all patients who do not have any medical contraindications to this method of treatment.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intravenous or epidural patient-controlled analgesia in the elderly after major abdominal surgery.
Patient-controlled analgesia (PCA) with intravenous morphine and patient-controlled epidural analgesia (PCEA), using an opioid either alone or in combination with a local anesthetic, are two major advances in the management of pain after major surgery. However, these techniques have been evaluated poorly in elderly people. This prospective, randomized study compared the effectiveness on postoperative pain and safety of PCEA and PCA after major abdominal surgery in the elderly patient. ⋯ After major abdominal surgery in the elderly patient, patient-controlled analgesia, regardless of the route (epidural or parenteral), is effective. The epidural route using local anesthetics and an opioid provides better pain relief and improves mental status and bowel activity.

End-of-life care can be a challenge requiring the full range of a family physician's skills. Significant pain is common but is often undertreated despite available medications and technology. Starting with an appropriate assessment and following recommended guidelines on the use of analgesics, family physicians can achieve successful pain relief in nearly 90 percent of dying patients. ⋯ Side effects of pain medications should be anticipated and treated promptly, but good pain control should be maintained. The physical, psychologic, social and spiritual needs of dying patients are best managed with a team approach. Home visits can provide comfort and facilitate the doctor-patient relationship at the end of life.

Drug delivery by target-controlled infusion (TCI) allows automatic adjustments of the infusion rate of a drug to maintain a desired target concentration. Since drug effect is more closely related to blood concentration than to infusion rate, drug delivery via TCI is capable of creating stable blood concentrations of intravenous anaesthetics and analgesics. In this article the concept and history of TCI are described. ⋯ The use of TCI for postoperative analgesia is still experimental, but TCI can, in part, overcome the disadvantages associated with continuous infusions and patient-controlled analgesia regimens in the postoperative period. Although TCI is capable of creating stable blood concentrations, when the target concentration is changed the resulting effect correlates better with a theoretical effect site concentration. The efficacy of TCI systems that can perform effect-site steering are still to be explored.
