Association of epidural analgesia with cesarean delivery in nulliparas.
To evaluate whether epidural analgesia during the first stage of labor is associated with an increased risk of cesarean delivery. ⋯ Epidural analgesia may increase substantially the risk of cesarean delivery. Although the causal nature of this association remains open to debate, prenatal care providers should routinely discuss the risks and benefits of epidural analgesia with women during their pregnancies so that they can make informed decisions about the use of pain relief during labor.

The efficacy, applicability and side-effects of postoperative intravenous patient-controlled morphine analgesia: an audit of 1233 Chinese patients.
We analyzed data from 1233 Chinese patients of a wide age range who received patient-controlled analgesia (PCA) intravenous morphine for postoperative pain relief, during the period of January 1992 to May 1995. The analgesic regimen was standardized as follows: PCA bolus 1 to 1.5 mg; lock-out interval 5 minutes; one-hour maximum dose 0.075 to 0.1 mg.kg-1 and background infusion 0 or 0.5 mg.h-1. Most patients underwent major surgery that was broadly subclassified according to the anatomical area involved. ⋯ Most patients were satisfied (76.7% ranked "good") with their postoperative analgesia. The commonest reasons for dissatisfaction were inadequate pain relief, nausea and reluctance to self-control analgesic administration. It is concluded that PCA with intravenous morphine is effective and safe as a routine postoperative technique for Chinese surgical patients.

The inadequacies of conventional intramuscular opioid analgesia have fueled an expansion in the use of patient-controlled analgesia and epidural analgesia after surgery. This is not always accompanied by increased education and specialist supervision of ward staff and patients. ⋯ Frequent review of patients and regular education of ward staff by a specialist Pain Nurse have achieved a substantial reduction in side effects of epidural analgesia and improvement in efficacy of patient-controlled analgesia. We have shown that the advantages of patient-controlled analgesia can be largely negated by failure to address deficiencies in knowledge of pain management among ward staff and patients.
