Randomized Controlled Trial Comparative StudyA randomized comparison of automated intermittent mandatory boluses with a basal infusion in combination with patient-controlled epidural analgesia for labor and delivery.
Automated mandatory boluses (AMB), when used in place of a continuous basal infusion, have been shown to reduce overall local anesthetic consumption without compromising analgesic efficacy in patient-controlled epidural analgesia (PCEA). We hypothesized that our PCEA+AMB regimen could result in a reduction of breakthrough pain requiring epidural supplementation in comparison with PCEA with a basal infusion (PCEA+BI). ⋯ PCEA+AMB, when compared to PCEA+BI, confers greater patient satisfaction and a longer duration of effective analgesia after CSE despite reduced analgesic consumption.

Randomized Controlled TrialUltrasound decreases the failed labor epidural rate in resident trainees.
Epidural analgesia is widely used for pain relief during labor. The purpose of this study was to determine if ultrasound measurement of the depth from skin to epidural space before the epidural technique decreases the failure rate of labor analgesia. A secondary objective was to correlate ultrasound depth to the epidural space with actual depth of the needle at placement. ⋯ Ultrasound measurement of the epidural space depth before epidural technique placement decreases the rate of epidural catheter replacements for failed labor analgesia, and reduces the number of epidural attempts when performed by first year residents and compared to attempts without ultrasound guidance.

Randomized Controlled Trial Comparative StudyAddition of low-dose morphine to intrathecal bupivacaine/sufentanil labour analgesia: A randomised controlled study.
Single-shot spinal analgesia with bupivacaine and a short-acting opioid for labour pain is popular due to its simplicity, rapid onset, and profound analgesia without significant motor block. Its limitation is the short duration of action. Supplementation with intrathecal morphine has been shown to prolong analgesia. We compared the addition of placebo or morphine 50 or 100 μg to intrathecal bupivacaine and sufentanil to evaluate the impact on duration of labour analgesia. ⋯ The addition of 50 or 100 μg morphine to 1.25mg bupivacaine and 5 μg sufentanil during established labour did not significantly increase the duration of analgesia.

Case ReportsThe successful use of extra-corporeal membrane oxygenation in the management of a pregnant woman with severe H1N1 2009 influenza complicated by pneumonitis and adult respiratory distress syndrome.
We report a case of H1N1 2009 influenza A, in a previously fit woman at 24 weeks of gestation, who presented atypically with abdominal pain. The infection was complicated by severe respiratory failure and acute respiratory distress syndrome, requiring ventilatory support, including extra-corporeal membrane oxygenation (ECMO). This was one of the first cases of severe H1N1 disease presenting in the UK. Use of extra-corporeal membrane oxygenation for the complications of H1N1 resulted in full maternal recovery and subsequent delivery of a healthy infant.

Clinical TrialSelf-reported post-discharge symptoms following obstetric neuraxial blockade.
Economic pressures are leading to earlier hospital discharge following delivery, before complications of obstetric neuraxial block may become apparent. Our aim was to estimate the incidence of symptoms presenting post-discharge at a single tertiary obstetric centre. ⋯ New post-discharge symptoms were self-reported by 1.4% of patients following neuraxial blockade. These were not detected during hospital stay despite routine directed post-block review. Only 4% of these symptoms could be directly attributable to neuraxial block.
