Multicenter StudyMechanical ventilation in critically-ill pregnant women: a case series.
Approximately 0.1-0.2% of pregnancies are complicated by respiratory failure requiring mechanical ventilatory support, but few data exist to inform clinical management. This study aimed to characterize current practice and the effect of delivery on respiratory function. ⋯ Review of current practice in four centers suggests that mechanical ventilation in pregnant patients follows usual guidelines applicable to non-pregnant patients. Delivery was associated with modest improvement in maternal respiratory function in some patients. Any potential benefit of delivery in improving maternal physiology must be weighed against the stress of delivery. The risks of premature birth for the fetus must be weighed against continued exposure to maternal hypoxemia and hypotension.

Randomized Controlled TrialPostural change from lateral to supine is an important mechanism enhancing cephalic spread after injection of intrathecal 0.5% plain bupivacaine for cesarean section.
Spinal anesthesia is widely used for cesarean section, but the factors that affect the spread of the block in pregnant patients are still not fully explained. This study was designed to investigate the effect of postural changes on sensory block level. ⋯ In our population, using 0.5% plain bupivacaine 7.5mg, postural change from the lateral position to the supine position is an important mechanism enhancing cephalic spread of spinal anesthesia during late pregnancy.

Case ReportsManagement of labor and delivery in a woman with Morquio syndrome.
Morquio syndrome, a congenital mucopolysaccharidosis, presents several challenges for the provision of effective labor analgesia. We report the case of a woman admitted for induction of labor who received an early epidural and subsequently required cesarean delivery. Optimal bilateral labor analgesia was not achieved despite multiple adjustments, and systemic analgesia was needed for cesarean delivery.
