Randomized Controlled TrialThe effect of adding magnesium sulphate to epidural bupivacaine and fentanyl in elective caesarean section using combined spinal-epidural anaesthesia: a prospective double blind randomised study.
Combined spinal-epidural anaesthesia is commonly used for elective caesarean section. Intrathecal injection produces rapid onset with minimal doses of local anaesthetic and epidural administration can be used to prolong the block. Our study examined the effects of adding magnesium sulphate to epidural bupivacaine and fentanyl in patients undergoing elective caesarean section using combined spinal-epidural anaesthesia. ⋯ The addition of magnesium to epidural bupivacaine and fentanyl in women undergoing elective caesarean section with combined spinal-epidural anaesthesia improved intraoperative conditions and the quality of postoperative 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.

Comparative StudyA comparison of a Neuropen monofilament and ethyl chloride for assessing loss of touch sensation during combined spinal-epidural anaesthesia for caesarean section.
Before caesarean section is performed under regional anaesthesia the block should be assessed, preferably using a touch stimulus. What constitutes a touch stimulus remains unclear. The aim of this study was to compare a Neuropen monofilament with ethyl chloride in the assessment of touch. ⋯ Data from this study suggest that a Neuropen monofilament and ethyl chloride are equivalent when used to assess a block to touch. However, subtle differences in the level of block to touch indicate that sensory level assessments should state the stimulus used. As the block to touch was below T5 at all time points, when opioids are added to local anaesthetics, T5 might no longer represent a necessary goal to ensure the absence of pain during caesarean section.

Minimum effective dose of spinal ropivacaine with and without fentanyl for postpartum tubal ligation.
Ropivacaine may be the ideal spinal anesthetic for postpartum tubal ligation due to its medium duration of action, low incidence of side effects and possibly reduced post-anesthetic care unit (PACU) stay. ⋯ Spinal hyperbaric ropivacaine 22 mg with or without fentanyl 10 μg could be used for postpartum tubal ligation surgery.
