Randomized Controlled Trial Comparative StudySpinal anaesthesia for caesarean section: an ultrasound comparison of two different landmark techniques.
Spinal anaesthesia performed at levels higher than the L3-4 intervertebral space may result in spinal cord injury. Our aim was to establish a protocol to reduce the chance of spinal anaesthesia performed at or above L2-3. ⋯ Our data suggest that when performing spinal anaesthesia in pregnant patients, if the intercristal line intersects an intervertebral space then the space below should be chosen and if the intercristal line intersects a spinous process then the interspace below should be chosen. This will reduce the incidence of spinal anaesthesia performed at or above L2-3.

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.
