Randomized Controlled Trial Comparative Study
Patient choice compared with no choice of intrathecal morphine dose for caesarean analgesia: a randomized clinical trial.
The study aimed to determine whether a patient's choice for their intrathecal morphine (ITM) dose reflects their opioid requirements and pain after caesarean delivery and if giving women a choice of ITM dose would reduce opioid use and improve pain scores compared with women who did not have a choice. ⋯ Women who were given a choice and chose the larger ITM dose correctly anticipated a greater postoperative opioid requirement and more pain compared with women who chose the smaller dose. Simply being offered a choice did not impact opioid use or pain scores after caesarean delivery.

Randomized Controlled Trial
Effect of caudal block using different volumes of local anaesthetic on optic nerve sheath diameter in children: a prospective, randomized trial.
Caudal block is commonly administered for postoperative analgesia in children. Although caudal block with 1.5 ml kg -1 local anaesthetic has been reported to reduce cerebral oxygenation in infants, the effect of caudal block on intracranial pressure (ICP) in children has not been well investigated. Optic nerve sheath diameter (ONSD) correlates with degree of ICP. This study aimed to estimate the effects of caudal block on ICP according to volume of local anaesthetic using ultrasonographic measurement of ONSD in children. ⋯ NCT02768493.

Randomized Controlled Trial Comparative Study
Efficacy and safety of carbetocin given as an intravenous bolus compared with short infusion for Caesarean section - double-blind, double-dummy, randomized controlled non-inferiority trial.
Carbetocin is a synthetic oxytocin-analogue, which should be administered as bolus according to manufacturer's recommendations. A higher speed of oxytocin administration leads to increased cardiovascular side-effects. It is unclear whether carbetocin administration as short infusion has the same efficacy on uterine tone compared with bolus administration and whether haemodynamic parameters differ. ⋯ ClinicalTrials.gov NCT02221531 and www.kofam.ch SNCTP000001197.

Randomized Controlled Trial Multicenter Study
Randomized trial of red cell washing for the prevention of transfusion-associated organ injury in cardiac surgery.
Experimental studies suggest that mechanical cell washing to remove pro-inflammatory components that accumulate in the supernatant of stored donor red blood cells (RBCs) might reduce inflammation and organ injury in transfused patients. ⋯ ISRCTN 27076315.
