Randomized Controlled Trial Comparative Study Clinical Trial[Peridural analgesia in labor. Comparison between bupivacaine and 2-chloroprocaine].
The purpose of this study was the comparison of the effects on the labor and neonates of epidural analgesia conducted either with bupivacaine or 2-chloroprocaine. Hundred and three parturients were included in the study. They were randomly divided in two groups. ⋯ Umbilical cord blood was drawn for pH determination. Cord blood pH was slightly but significantly lower in bupivacaine (7.314 +/- 0.106) than in 2-chloroprocaine (7.345 +/- 0.06) patients (t = 1.6968, p = 0.046). Newborns extracted with forceps after maternal bupivacaine epidural analgesia had a significantly lower umbilical blood pH (7.278 +/- 0.117) than newborns who did not required forceps in the bupivacaine group (7.337 +/- 0.093) (t = 2.1986, p = 0.0159).(ABSTRACT TRUNCATED AT 250 WORDS)

[Controlled hypotension during posterior vertebral arthrodesis; value of an isoflurane-nitroglycerin combination].
Eighteen young patients (mean age +/- SD 15.9 +/- 3.3) scheduled for operative treatment of idiopathic scoliosis (posterior spine fusion) were studied during surgery. Deliberate hypotension (MAP less than 60 mm Hg) of long duration (greater than 2 hours) was induced using isoflurane and nitroglycerin. Hypotension was effective in less than 15 min in all patients. ⋯ Intra operative awakening was obtained 22.8 +/- 3.7 min after isoflurane was discontinued. Isoflurane and nitroglycerin produce a stable and safe hypotension with no major hemodynamic disturbances. Isoflurane has to be discontinued 20 min before the wake-up test.
