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 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.

Headache is a common puerperal complaint. A wide variety of factors can be involved, ranging from hormonal shifts, physiological changes, and peripartum procedures that may precipitate, worsen, or cause troublesome headache. The differential diagnosis of postpartum headache is broad and potentially daunting to the various clinicians caring for the postpartum patient. ⋯ This review will focus on the main causes of postpartum headache, their incidence, and clinical presentation. Causes of postpartum headache that will be covered include benign primary headache disorders such as migraine and tension type headache as well as secondary headache disorders such as postdural puncture headache, stroke, and venous sinus thrombosis. A structured approach to headache evaluation in the postpartum patient will be presented to help differentiate the possible causes of headache.

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 ReportsNon-invasive mechanical ventilation with spinal anesthesia for cesarean delivery.
We present the successful use of perioperative non-invasive mechanical ventilation in a morbidly obese pregnant woman with bronchial asthma, severe preeclampsia and pulmonary edema undergoing an emergency cesarean delivery with spinal anesthesia. The combination of non-invasive mechanical ventilation with neuraxial anesthesia may be of value in selected parturients with acute or chronic respiratory insufficiency requiring surgery.
