Awareness during general anaesthesia for Caesarean section (C/S), although uncommon, remains a concern for anaesthesiologists. We examined the relationship between the bispectral index (BIS) and responses to the isolated forearm technique (IFT) to evaluate the adequacy of general anaesthesia in C/S and determine a suitable cut-off point for BIS values based on IFT results. ⋯ The BIS is not reliable for monitoring anaesthesia depth in C/S. Lower than previously recommended values are needed to avoid IFT test responses during laryngoscopy, intubation, and skin incision.

Randomized Controlled Trial
Analgesic efficacy of caudal dexamethasone combined with ropivacaine in children undergoing orchiopexy.
Epidural administration of dexamethasone might reduce postoperative pain in adults. We evaluated whether a caudal block of 0.1 mg kg(-1) dexamethasone combined with ropivacaine improves analgesic efficacy in children undergoing day-case orchiopexy. ⋯ The addition of dexamethasone 0.1 mg kg(-1) to ropivacaine for caudal block can significantly improve analgesic efficacy in children undergoing orchiopexy. Clinical trial registration NCT01604915.

Randomized Controlled Trial Comparative Study
Dexmedetomidine vs remifentanil intravenous anaesthesia and spontaneous ventilation for airway foreign body removal in children.
To compare the safety and efficacy of dexmedetomidine/propofol (DP)-total i.v. anaesthesia (TIVA) vs remifentanil/propofol (RP)-TIVA, both with spontaneous breathing, during airway foreign body (FB) removal in children. ⋯ Compared with RP-TIVA, DP-TIVA provided more stable respiratory and haemodynamic profiles, but required a longer recovery time. Clinical trial registration China Clinical Research Information Service, ChiCTR-TRC-13003018.
