A review of the charts of 198 patients who were admitted through the emergency department with a variety of acutely painful medical and surgical conditions revealed that 56% received no analgesic medication while in the emergency department. In the 44% of patients who received pain medication, 69% waited more than 1 hour while 42% waited more than 2 hours before narcotic analgesia was administered. In addition, 32% initially received less than an optimal equianalgesic dose of narcotic when compared with morphine. This study demonstrates that narcotic misues, in the form of oligoanalgesia, is prevalent and is the shared responsibility of both emergency physicians and housestaff consultants.

Randomized Controlled Trial Comparative Study Clinical TrialMaternal analgesia and neonatal effects of epidural sufentanil for cesarean section.
This study was designed to evaluate the maternal intraoperative and postoperative analgesia and neonatal effects of adding sufentanil to epidural anesthesia for cesarean section before the skin incision. Forty-five multipara were randomized in three equal groups to receive sufentanil 80 micrograms, 50 micrograms, or saline with the epidural lidocaine. Intraoperative and postoperative analgesia and side effects were recorded. ⋯ Postoperative analgesia was prolonged after sufentanil, but side effects increased with the greater dose. The infants whose mothers received 80 micrograms sufentanil showed a mild neurobehavioral depression. It is therefore concluded that the addition of 50 micrograms of sufentanil improves both intraoperative and postoperative analgesia without significant neonatal effects.

The efficacy of transcutaneous electrical nerve stimulation (TENS) in producing analgesia in cold-induced pain was assessed using a range of 5 stimulating frequencies (10 Hz, 20 Hz, 40 Hz, 80 Hz and 160 Hz) in 83 normal healthy subjects. TENS significantly elevated ice pain threshold when compared with sham and control groups. ⋯ Measurement of ice pain tolerance was found to be unreliable under the present conditions. No significant relationships were observed between personality variables as measured by Eysenck Personality Questionnaires and the degree of TENS response.

Intrathecally administered clonidine has been reported to produce analgesia in cancer patients tolerant to intrathecal opiates. To assess the efficacy, safety, and appropriate dose of epidurally administered clonidine for the treatment of cancer pain, clonidine (range, 100-900 micrograms in 100-micrograms increments) was injected in nine patients with severe, intractable cancer pain. Clonidine produced analgesia, as measured by change in verbal pain scores, lasting more than 6 h. ⋯ Clonidine was absorbed in a dose-dependent manner into the systemic circulation, although absorption and elimination kinetics were highly variable. Following study seven patients received epidural clonidine/morphine infusions at home for periods of up to 5 months with sustained analgesia. These results suggest that epidurally administered clonidine may offer effective analgesia in patients with severe, intractable cancer pain.
