Starting with the earliest biographies of James Young Simpson, the topic of religious opposition to obstetric anaesthesia in 1847 was gradually embellished in historical articles. Objective data are lacking and it has been suggested that this is a myth of recent medical history. ⋯ This revealed a marked increase (P<0.01) in the provision of anaesthesia for childbirth after the publication of Simpson's pamphlet in December 1847. This analysis supports the existence of opposition to obstetric anaesthesia and the success of Simpson's pamphlet in overcoming it, but the introduction of chloroform about six weeks earlier, may also have contributed.

Programmed intermittent epidural boluses for maintenance of labor analgesia: an impact study.
The aim of this impact study was to compare the analgesic efficacy and side effect profile of programmed intermittent epidural boluses (PIEB)+patient-controlled epidural analgesia (PCEA) to continuous epidural infusion (CEI)+PCEA for maintenance labor analgesia after the introduction of PIEB at our institution. ⋯ Using PIEB compared to CEI as the background maintenance epidural analgesia method in conjunction with PCEA reduced the number of women requiring clinician rescue boluses while providing comparable labor analgesia. The findings of this clinical care impact study confirm the results of randomized controlled studies and suggest PIEB may be a preferable technique to CEI for the maintenance of labor analgesia.
