Randomized Controlled Trial Comparative Study
Intermittent vs continuous administration of epidural ropivacaine with fentanyl for analgesia during labour.
Many years ago regular intermittent bolus administration of epidural local anaesthetic solution was recognized to produce more effective analgesia than continuous infusion, but only recently has the development of suitable pumps allowed the former technique's wider evaluation. ⋯ The intermittent group required fewer supplementary injections and less drug to maintain similar pain scores, sensory and motor block compared with the continuous group. This represents a more efficacious mode of analgesia.

Randomized Controlled Trial Comparative Study
Continuous spinal microcatheter (28 gauge) technique for arterial bypass surgery of the lower extremities and comparison of ropivacaine with or without morphine for postoperative analgesia.
The aim of this study was to evaluate a microcatheter technique for continuous spinal anaesthesia (CSA) and continuous spinal postoperative analgesia (CSPA) in vascular surgery. ⋯ The described CSA technique offered good haemodynamic control, ease of maintaining spinal anaesthesia, and ease of providing a new spinal block for revision. The combination of low-dose ropivacaine and morphine for CSPA did not offer any benefit compared with the higher ropivacaine dose alone.

Comparative Study
Cerebral state index: comparison between pairwise registrations from the left and the right sides of the brain.
Lateralization of cerebral blood flow and EEG activity is known to vary during cognition, sleep and waking. In spite of this, electrode placement for the cerebral state index (CSI) monitor is not specified to a particular side of the brain. This study is designed to determine if pairwise registrations differ for CSI measured simultaneously from the left or right sides of the brain. ⋯ Despite known lateralization of the EEC, this study found a very high correlation in CSI derived simultaneously from the left and right sides of the brain by two independent monitors.
