Life-threatening extensions of conduction block during obstetric epidural analgesia can be classified according to the risk to the mother. High blocks that occur in the presence of the anaesthetist should present a readily treatable problem. Reports of total spinal anaesthesia that occur with no anaesthetist in attendance call for a reappraisal of present practice. Changes in current anaesthetic practice, which might increase safety with epidural analgesia, are top-ups by midwives, but only when the anaesthetist is on the delivery suite; repeated assessment of the nature of the conduction block by an anaesthetist; and continuous infusions with anaesthetist-only top-ups.

On admission to a pain management unit, 92.5% of 174 cancer patients suffered from more than moderate pain despite prior treatment. This inefficacy was mainly due to underdosage of drugs, inadequate intake schedule, and hesitation to use strong opioids. Following introduction of an oral drug therapy based on World Health Organization (WHO) guidelines, more than 80% of all patients described their pain as ranging between "none" and "moderate" on a six-step verbal rating scale at all times. ⋯ Step III (strong opioids) gained more and more importance with time, and step I (nonopioids) was finally useful only in a minority of patients. Side effects played a minor role as a reason to change therapy. Oral drug therapy following these guidelines led to sufficient pain control in most patients over the whole study period (7,400 days); only 11% of the patients required other methods of pain management.

Randomized Controlled Trial Clinical TrialA prospective study of patient-controlled analgesia. Impact on overall hospital course.
Previous studies have shown that patient-controlled analgesia (PCA) provides effective pain control in the postoperative patient. To determine the impact of PCA technology on the overall hospital course, we designed a randomized controlled study comparing patients receiving analgesia using PCA infusion (Abbott Lifecare, Abbott Laboratories; Chicago, IL) with patients receiving analgesia by traditional intramuscular or intravenous methods. All patients had undergone elective cholecystectomy. ⋯ Patients demonstrated a wide range of analgesic requirement in the first 24 hours but the average of the total analgesic required was higher in the PCA group (average, 29.5 mg) than the traditional group (22.8 mg). Urinary complications occurred more commonly in the group of patients receiving traditional analgesia than in the group of patients receiving analgesia with the PCA device. When compared with patients receiving analgesia by traditional methods, patients receiving the PCA infusion required more analgesia with fewer urinary complications and similar postoperative length of stay.
