Randomized Controlled TrialPrevention versus treatment of intrathecal morphine-induced pruritus with ondansetron.
Intrathecal morphine is used for post-cesarean analgesia, but pruritus is a common side effect. Ondansetron would be an attractive treatment because it prevents nausea, is non-sedative or has no anti-analgesic effect. We undertook a study to assess the efficacy of ondansetron for treatment or prophylaxis of intrathecal morphine-induced pruritus. ⋯ Prophylactic ondansetron did not reduce pruritus when compared with placebo. The use of ondansetron as a treatment did not decrease the severity of pruritus when compared with placebo.

Randomized Controlled Trial Comparative StudyUltrasound-guided spinal anaesthesia in obstetrics: is there an advantage over the landmark technique in patients with easily palpable spines?
Data are scarce on the advantage of ultrasound-guided spinal anaesthesia in patients with easily identifiable bony landmarks. In this study, we compared the use of ultrasound to the landmark method in patients with no anticipated technical difficulty, presenting for caesarean delivery under spinal anaesthesia. ⋯ The present results indicate that when performed by anaesthetists experienced in both ultrasound and landmark techniques, the use of ultrasound does not appear to increase the success rate of spinal anaesthesia, or reduce the procedure time or number of attempts in obstetric patients with easily palpable spines.

Randomized Controlled TrialEvaluation of levobupivacaine passage to breast milk following epidural anesthesia for cesarean delivery.
Following maternal administration, local anesthetics pass into breast milk. In the present study, we aimed to compare the passage of levobupivacaine and bupivacaine into breast milk following epidural anesthesia for cesarean delivery. ⋯ Both levobupivacaine and bupivacaine pass into breast milk following epidural administration. The concentration of both drugs was approximately three times lower in breast milk than in maternal plasma.

Randomized Controlled TrialEffects of a head elevated ramped position during elective caesarean delivery after combined spinal-epidural anaesthesia.
Elevating the torso in a Head Elevated Ramped Position during caesarean delivery benefits the mother by improving comfort and ventilation while reducing reflux symptoms and providing a better airway position. We hypothesised that using an elevation pillow for an elective caesarean delivery under combined spinal-epidural anaesthesia would not significantly increase the time to achieve a T4 block. ⋯ Elevating the parturient undergoing elective caesarean delivery into the Head Elevated Ramped Position immediately or once the block had been established did not appear to significantly alter time to an adequate block height of T4; however, the need for epidural supplementation was greater in the intervention groups. Cautious use of this novel position change can provide a more comfortable experience and provide a better airway position should conversion to general anaesthesia be required.

Randomized Controlled Trial Comparative StudyA randomized, observer-blind comparison between the Neurotip mounted Neuropen and a disposable plastic neurological wheel for assessing the level of spinal blockade at cesarean section.
Various methods are used to assess the height of sensory block to touch under spinal anesthesia for cesarean section. We tested a novel, inexpensive, miniature, user-dependent plastic neurological wheel against the user-independent Neurotip mounted Neuropen. ⋯ The compact plastic neurological wheel is as clinically reliable as the Neurotip mounted Neuropen.
