Clinical TrialMajor complications after 400 continuous popliteal sciatic nerve blocks for post-operative analgesia.
A continuous popliteal sciatic nerve block (CPSNB) has been performed with increasing frequency for post-operative analgesia after foot surgery. Major complications associated with the placement of a perineural catheter remain rarely studied. The aim of this study was to prospectively determine the incidence of major complications (neurological and infectious) in post-operative adult patients with a continuous popliteal catheter inserted by the anatomical posterior approach for analgesia after foot surgery. ⋯ Major complications after the use of CPSN are not in fact rare. The incidence of severe neuropathy or infection complications is, respectively, 0.50% and 0.25%. However, the insertion of CPSN could be considered effective and is associated with only a few minor complications.

Randomized Controlled Trial Comparative StudyComparison of closed loop vs. manual administration of propofol using the Bispectral index in cardiac surgery.
In recent years, electroencephalographic indices of anaesthetic depth have facilitated automated anaesthesia delivery systems. Such closed-loop control of anaesthesia has been described in various surgical settings in ASA I-II patients (1-4), but not in open heart surgery characterized by haemodynamic instability and higher risk of intra-operative awareness. Therefore, a newly developed closed-loop anaesthesia delivery system (CLADS) to regulate propofol infusion by the Bispectral index (BIS) was compared with manual control during open heart surgery. ⋯ The automated delivery of propofol using CLADS was safe, efficient and performed better than manual administration in open heart surgery.
