Randomized Controlled Trial Comparative StudyPulmonary effects of bupivacaine, ropivacaine, and levobupivacaine in parturients undergoing spinal anaesthesia for elective caesarean delivery: a randomised controlled study.
Spinal anaesthesia is the method of choice for elective caesarean delivery, but has been reported to worsen dynamic pulmonary function when using bupivacaine. Similar investigations are lacking for ropivacaine and levobupivacaine. We have therefore compared the pulmonary effects of intrathecal bupivacaine, ropivacaine and levobupivacaine used for caesarean delivery. ⋯ Decreases in maternal pulmonary function tests were similar following spinal anaesthesia with bupivacaine, ropivacaine, or levobupivacaine for caesarean delivery. The clinical maternal and neonatal effects of these alterations appeared negligible.

Case ReportsReversal of prolonged rocuronium neuromuscular blockade with sugammadex in an obstetric patient with transverse myelitis.
A 38-year-old wheelchair-bound primigravida with transverse myelitis presented at 38 weeks of gestation for elective caesarean section. Transverse myelitis, which is characterised by bilateral inflammation of the spinal cord and myelin destruction, is associated with myopathy, autonomic dysreflexia and pulmonary aspiration. Regional anaesthesia was contraindicated in this case as the patient had undergone two previous lumbar spinal fusion procedures. ⋯ We believe that myopathy associated with transverse myelitis led to the prolonged duration of action of rocuronium. Sugammadex is a relatively new drug with few reported side effects. In this case it was used to reverse neuromuscular blockade and prevented prolonged postoperative ventilatory support.

Anesthetic management of a consecutive cohort of women with heart disease for labor and delivery.
The cardiovascular changes of pregnancy may place additional stress upon women with pre-existing heart disease, increasing peripartum morbidity and mortality. The purpose of this descriptive study was to report the anesthetic management of a large cohort of pregnant women with heart disease. ⋯ Pregnant women with heart disease managed within an organized program may undergo labor and delivery with acceptable rates of complications. Cesarean section, epidural analgesia/anesthesia and general anesthesia rates are similar to those in the general obstetric population.

Randomized Controlled Trial Comparative StudyPerineal infiltration with lidocaine 1%, ropivacaine 0.75%, or placebo for episiotomy repair in parturients who received epidural labor analgesia: a double-blind randomized study.
Episiotomies are performed in approximately 20% of vaginal deliveries and may result in postpartum pain. Perineal infiltration with lidocaine during the episiotomy is widely used, despite an early study showing no difference when compared with saline. Ropivacaine has increasingly been used in the obstetric setting, although not for episiotomies. We sought to compare the analgesic efficacy of ropivacaine, lidocaine or saline for perineal infiltration before repair of a mediolateral episiotomy in patients who delivered with epidural labor analgesia. ⋯ For the first 24 h, perineal infiltration of ropivacaine, lidocaine, and saline were equivalent in producing post-episiotomy analgesia.

Randomized Controlled TrialSensory testing of spinal anaesthesia for caesarean section: differential block and variability.
The aim of this study was to determine if sensory block following spinal anaesthesia, measured with a range of devices, corresponded to the hierarchy of nerve fibre size in the area of differential block, and to compare the distribution and variability of recorded measurements. ⋯ Sensory fibre hierarchy could be identified. Tests for light touch showed the least variability. More expensive tests do not appear to have any advantage over the least expensive test, cotton wool.
