Randomized Controlled Trial Clinical TrialMetoclopramide: an analgesic adjunct to patient-controlled analgesia.
This randomized, double-blind trial evaluated the effect of metoclopramide on the pain and analgesic requirements associated with prostaglandin-induced labor for second-trimester termination of pregnancy. After receiving intrauterine prostaglandin, seven women were given intravenous metoclopramide (10 mg), and eight received saline, concurrent with initiation of patient controlled analgesia (PCA). ⋯ We conclude that a single dose of metoclopramide reduces the pain and PCA-morphine requirements of patients undergoing prostaglandin-induced labor and may facilitate passage of the fetus. Metoclopramide may have a similar application in treating other types of gynecologic pain.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intermittent bolus with continuous infusion of epidural morphine in the treatment of severe cancer pain.
Twenty-eight patients with severe pain due to cancer, who could no longer obtain acceptable pain relief from optimised doses of oral opioids, were entered into a study which compared pain relief, satisfaction with pain therapy and estimates of neuropsychological functioning during treatment with spinally administered (i.e., epidural and intrathecal) morphine as either repeated bolus doses or as a continuous infusion. These measures of efficacy and side effects were repeated every 2 weeks until either the patient died (82% of patients), withdrew from the study or were no longer able to complete the tests due to deterioration of their condition. The mean (range) duration of treatment was 169 (6-537) days for those patients receiving continuous infusion and 140 (28-378) days for those patients receiving repeated bolus doses. ⋯ There was a significantly greater degree of dose escalation in patients receiving continuous infusion compared to patients receiving repeated bolus doses. For 6 patients in the infusion group the catheter was sited in the intrathecal space, as the dose requirements by the epidural route exceeded the delivery capacity of the pump. For 4 patients in the bolus group the catheter was similarly sited, due to pain on injection and leakage/blockage.(ABSTRACT TRUNCATED AT 250 WORDS)

ReviewUse of patient-controlled analgesia with critically ill patients: a risk/benefit analysis.
Patient-controlled analgesia (PCA), a system by which patients self-administer intravenous doses of narcotics using specially programmed infusion pumps, has been used for pain management in acute care settings for nearly two decades. The safety and effectiveness of PCA has been documented in many acutely ill patient populations. ⋯ However, intravenous narcotics of any type can provoke hemodynamic or respiratory complications in these compromised patients. Nursing expertise is a key factor in the successful implementation of PCA in critically ill patients.

Randomized Controlled Trial Comparative Study Clinical TrialIntravenous ketamine for prevention of severe hypotension during spinal anaesthesia.
Spinal block causes paralysis of preganglionic sympathetic fibres, while ketamine induces activation of the sympathetic nervous system. Hypotension is a frequent complication during spinal anaesthesia and is associated with an increased risk of postoperative mortality. The aim of our study was to compare circulatory changes in patients who received either fentanyl or ketamine during spinal anaesthesia. ⋯ In the fentanyl group six subjects developed a haemodynamically unstable condition, while only one subject in the ketamine group was registered as such (P less than 0.05). There was no significant change in heart rate in either group. We conclude that during spinal anaesthesia patients can in part be kept haemodynamically stable by intravenous administration of ketamine.

ReviewEfficacy of epidural analgesia for pain management of critically ill patients and the implications for nursing care.
Management of pain for critically ill patients has been shown to be inadequately controlled and can have serious deleterious effects on a patient's recovery. Continuous epidural analgesia can be used to control pain in critical care patients. This mode of analgesia administration provides pain relief without the delays inherent in the as-needed administration of analgesics. ⋯ Evaluation of the effectiveness of the analgesia was based on the following measures: 1) pain measured at regular intervals in the 72-hour period with a visual analog; 2) pain as measured after 72 hours with the word descriptor section of the McGill pain questionnaire; 3) amount of supplemental systemic narcotic analgesic needed; 4) recovery of ambulatory and respiratory function, including ability to perform coughing and deep-breathing exercises; 5) occurrence of adverse effects, and 6) the type and distribution of nursing care problems associated with continuous epidural infusions. The results of this study showed that the level of pain relief and recovery of postoperative function was superior to that provided by the more widely used as-needed systemic administration of narcotics. Although some nursing care problems were identified, continuous epidural analgesia can be used for pain relief in critical care patients, if the analgesia is administered by accurate reliable infusion systems and carefully monitored by nursing staff who are knowledgeable about the pharmacologic considerations of epidural analgesic agents and the management of patient care.
