Randomized Controlled Trial Comparative StudyA randomized controlled trial comparing intrathecal morphine with transversus abdominis plane block for post-cesarean delivery analgesia.
Intrathecal morphine is an effective analgesic post-cesarean delivery; however, it may be contraindicated or unsuitable in some patients. We compared the efficacy and side effects of intrathecal morphine with an ultrasound-guided transversus abdominis plane (TAP) block in a randomized, controlled, double-blinded trial. The primary outcome was the morphine equivalents dose used in the first 24 h post-surgery. Secondary outcomes were pain scores and side effects, including pruritus, sedation, nausea and vomiting. ⋯ In this trial, the TAP block was associated with greater supplemental morphine requirements and higher pain scores than intrathecal morphine but fewer opioid-related side effects. The TAP block may be a reasonable alternative when intrathecal morphine is contraindicated or not appropriate.

Randomized Controlled TrialA sequential compression mechanical pump to prevent hypotension during elective cesarean section under spinal anesthesia.
Spinal anesthesia is a standard technique for cesarean section but can cause hypotension which may be related to venous pooling secondary to progesterone-induced decreases in vascular tone. This study investigated the use of a sequential compression mechanical pump with thigh-high sleeves with compression cycles timed to venous refilling. We hypothesized that this would recruit pooled venous blood from the lower limbs, maintain the central blood volume and thus decrease the incidence of hypotension. ⋯ The use of a sequential compression mechanical pump that detects venous refilling and cycles accordingly, reduced the incidence and severity of hypotension after spinal anesthesia for cesarean section.

Case ReportsAnesthetic management of a spontaneous spinal-epidural hematoma during pregnancy.
Spontaneous spinal-epidural hematoma is uncommon and rare during pregnancy. We were presented with a 31-year-old patient who developed back pain with lower extremity paralysis at 36 weeks of gestation. ⋯ Postoperatively, dopamine was infused to maintain the blood pressure within the high-normal range to optimize spinal cord perfusion. Successful anesthetic and postoperative management is described together with a review of the literature.
