Fifteen patients with cancer pain refractory to other methods of pain control were treated with epidural sufentanil. They all suffered from very severe or unbearable pain but had expressed the wish to spend the last period of their lives at home. On the first day of hospitalization, an epidural catheter and a portal catheter were implanted under local anesthesia. ⋯ Nine patients had epidural sufentanil as their sole analgesic till they died; six patients needed adjunctive nonepidural medications. There were no epidural- or portal-catheter related infections or cases of respiratory depression. After 1651 patient treatment days, we have found continuous epidural sufentanil infusion to be a safe and effective method for cancer pain control in outpatients.

Comparative StudyBupivacaine/butorphanol/epinephrine for epidural anesthesia in obstetrics: maternal and neonatal effects.
The effects of epidural bupivacaine/butorphanol with and without 1:300,000 epinephrine on maternal analgesia, uterine activity, progress of labor, fetal heart rate, maternal blood pressure, newborn Apgar scores, neonatal acid base status and the neurologic and adaptive capacity scores (NACS) were compared in 33 parturients during labor and delivery. Patients in Group I (n = 17) received 0.25% bupivacaine plus 1 mg butorphanol plus 1:300,000 epinephrine, and those in Group II (n = 16) received the same agents without the epinephrine. Addition of epinephrine to bupivacaine/butorphanol did not have any adverse effects on uterine activity, duration of first or second stages of labor or fetal heart rate parameters. ⋯ Apgar scores, neonatal acid base status and the NACS were equally good and did not differ significantly between the two groups. Duration of analgesia was significantly longer in Group I as compared to Group II patients (177.5 +/- 11 versus 131.8 +/- 10 minutes, p less than 0.01). It is concluded that addition of epinephrine 1:300,000 to bupivacaine/butorphanol during epidural anesthesia in the normal parturient has no adverse effects on the mother, fetus or neonate or on the progress of labor and it significantly prolongs the duration of analgesia.

Case ReportsSpinal cord compression following labor and delivery with epidural analgesia.
Transient back pain is not uncommon during pregnancy and the postpartum period. Following an epidural anesthetic, back pain persisted in a postpartum patient beyond the expected period of soreness. Further diagnostic evaluation led to diagnosis and surgical decompression of a herniated thoracic disc.

The subjective complications and efficiency of the epidural blood patch in the treatment of postdural puncture headache.
The complications and efficacy of epidural blood patch were studied retrospectively by means of a questionnaire sent to 236 patients. Hospital records were also studied. ⋯ Epidural blood patch was found to be effective; 84.5% of the respondents had complete and permanent recovery from headache in less than 24 hours after a single epidural blood patch. Of those responding, 42.3% were willing to undergo spinal anesthesia in the future, when indicated, only if they could be assured of getting epidural blood patch in the event of a postdural puncture headache.

Randomized Controlled Trial Clinical TrialAlkalinization of epidural 0.5% bupivacaine for cesarean section.
Controversial results have been published in the literature concerning the efficacy of alkalinization of solutions of local anesthetics to shorten the time to onset of sensory block. Fifty-two parturients scheduled for cesarean section at term under epidural anesthesia were randomly allocated to one of four groups: group 1, 0.5% plain bupivacaine (pH = 5.38 +/- 0.05); group 2, 0.5% bupivacaine pH-adjusted with 1.4% sodium bicarbonate (pH = 6.87 +/- 0.01); group 3, 0.5% bupivacaine with 1:200,000 epinephrine (pH = 4.80 +/- 0.04); and group 4, 0.5% bupivacaine pH-adjusted with 1:200,000 epinephrine (pH = 6.68 +/- 0.01). The time to onset of the sensory block was evaluated using a nerve stimulator technique. ⋯ No differences in the characteristics of the onset of the sensory block were observed with epinephrine-containing solutions nor with pH-adjusted local anesthetics. The maximal degree of motor blockade was not significantly different in the four groups. We conclude that alkalinization of a 0.5% bupivacaine solution is not an effective way to shorten the latency of epidural block for cesarean section.
