Randomized Controlled Trial Comparative Study
Comparison of motor-evoked potentials monitoring in response to transcranial electrical stimulation in subjects undergoing neurosurgery with partial vs no neuromuscular block.
There have been no evidence-based comparisons of motor-evoked potential (MEP) monitoring with no and partial neuromuscular block (NMB). We compared the effects of different levels of NMB including no NMB on MEP parameters. ⋯ If NMB is used during MEP monitoring, a target T(2)/Tc of 0.5 is recommended. In terms of the MEP amplitude and variability, no NMB was more desirable than any level of partial NMB.

Randomized Controlled Trial
Randomized controlled trial of goal-directed haemodynamic treatment in patients with proximal femoral fracture.
Patients with proximal femoral fracture (PFF) are at high risk of postoperative complications. Goal-directed haemodynamic treatment (GDHT) in other high-risk surgical patients reduces postoperative complications. We aimed to compare effects of GDHT and routine fluid treatment (RFT) on postoperative outcomes after PFF surgery. ⋯ The magnitude of risk reduction of postoperative complications is clinically relevant, but the trial was underpowered and the null hypothesis cannot be rejected.

Randomized Controlled Trial
Effect of intravenous fluid therapy on postoperative vomiting in children undergoing tonsillectomy.
Postoperative vomiting (POV) is one of the most frequent complications of tonsillectomy in children. The aim of this study was to evaluate the antiemetic effect of super-hydration with lactated Ringer's solution in children undergoing elective otorhinolaryngological surgery. ⋯ Intraoperative administration of 30 ml kg(-1) h(-1) lactated Ringer's solution significantly reduced the incidence of POV during the first 24 h postoperative. Our results support the use of super-hydration during tonsillectomy, as an alternative way to decrease the risk of POV in children.
