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.

The analgesic effect of lornoxicam when added to lidocaine for intravenous regional anaesthesia.
The aim of the study was to evaluate the effect of lornoxicam (L) on sensory and motor block onset time, tourniquet pain, and postoperative analgesia, when added to lidocaine in intravenous regional anaesthesia (IVRA). ⋯ The addition of lornoxicam to lidocaine for intravenous regional anaesthesia shortens the onset of sensory and motor block, decreases tourniquet pain and improves postoperative analgesia without causing any side effect.

Randomized Controlled Trial
Correlation and agreement between bispectral index and state entropy of the electroencephalogram during propofol anaesthesia.
Bispectral index (BIS) and state entropy (SE) monitor hypnosis. We evaluated the correlation and the agreement between those parameters during propofol anaesthesia and laryngoscopy with and without muscle relaxation. ⋯ BIS and SE are globally well correlated. In contrast, agreement is poor as differences of more than 20 units are frequently observed, except for awake and paralysed patients.

Randomized Controlled Trial Comparative Study
Cerebral haemodynamic changes during propofol-remifentanil or sevoflurane anaesthesia: transcranial Doppler study under bispectral index monitoring.
Sevoflurane or propofol-remifentanil-based anaesthetic regimens represent modern techniques for neurosurgical anaesthesia. Nevertheless, there are potential differences related to their activity on the cerebrovascular system. The magnitude of such difference is not completely known. ⋯ Propofol-remifentanil anaesthesia induced a dose-dependent low-flow state with preserved cerebral autoregulation, whereas sevoflurane at high doses provided a certain degree of luxury perfusion.

Randomized Controlled Trial
Efficacy of three doses of tramadol with bupivacaine for caudal analgesia in paediatric inguinal herniotomy.
This study was designed to evaluate the analgesic efficacy of three doses of tramadol, administered caudally with bupivacaine, in providing postoperative pain relief in children. ⋯ Caudal tramadol 2 mg kg(-1), combined with bupivacaine 0.25% 0.75 ml kg(-1), provided longer duration of postoperative analgesia and reduced requirement for rescue analgesic compared with tramadol 1 mg kg(-1) or 1.5 mg kg(-1) in children undergoing inguinal herniotomy.
