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.

Randomized Controlled Trial
Effect of adductor canal block on pain in patients with severe pain after total knee arthroplasty: a randomized study with individual patient analysis.
Total knee arthroplasty (TKA) is associated with varying degrees of pain. A considerable proportion (25-40%) of patients experience severe pain, despite a comprehensive multimodal analgesic regimen. We hypothesized that adductor canal block (ACB) would reduce pain in this patient category compared with placebo. ⋯ ACB reduced VAS with 32 mm, during active flexion of the knee, in patients with severe pain after TKA, but a large proportion (78%) still had at least moderate, movement-related pain. Clinical trial registration www.clinicaltrials.gov, NCT01549704.

Randomized Controlled Trial Comparative Study
Comparison of gas exchange after lung resection with a Boussignac CPAP or Venturi mask.
Postoperative continuous positive airway pressure (CPAP) can improve lung function. The aim of our study was to assess the efficacy of prophylactic CPAP on the Pa(O2)/FI(O2) ratio measured the day after surgery in patients undergoing lung resection surgery (LRS). ⋯ In patients undergoing LRS, prophylactic CPAP during the first 6 h after surgery with a pressure of 5-7 cm H2O improved the Pa(O2)/FI(O2) ratio at 24 h. This effect was more evident in patients with increased risk of postoperative pulmonary complications.

Randomized Controlled Trial Multicenter Study
Nitrous oxide does not produce a clinically important sparing effect during closed-loop delivered propofol-remifentanil anaesthesia guided by the bispectral index: a randomized multicentre study.
Nitrous oxide (N2O) offers both hypnotic and analgesic characteristics. We therefore tested the hypothesis that N2O administration decreases the amount of propofol and remifentanil given by a closed-loop automated controller to maintain a similar bispectral index (BIS). ⋯ With automated drug administration titrated to comparable BIS, N2O only slightly reduced propofol consumption and did not reduce remifentanil consumption. There was a minor gender dependence, but not by a clinically important amount. Clinical trial registration This study was registered at ClinicalTrials.gov, number NCT00547209.
