Randomized Controlled Trial Comparative Study
Comparison of the Surgical Pleth Index with autonomic nervous system modulation on cardiac activity during general anaesthesia.
Surgical plethysmographic index (SPI) has been proposed as a tool to measure the nociception/antinociception balance during general anaesthesia. Untreated nociception may increase sympathetic tone, but the relationship between SPI and the autonomic nervous system (ANS) is poorly understood. ⋯ In the context of a balanced general anaesthesia in healthy patients undergoing laparoscopic abdominal surgery, ANS modulation seems to correlate with changes in SPI. Further studies are warranted to assess whether this may reflect a change in nociception/antinociception balance or a pharmacodynamic effect of remifentanil.

Observational Study
Effect of head rotation during surgery in the prone position on regional cerebral oxygen saturation: A prospective controlled study.
Near-infrared spectroscopy (NIRS) has been used to study regional cerebral blood oxygen saturation (rScO2) in patients in the prone position. ⋯ We recommend the neutral head position for prone patients.TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01760369.

Observational Study
Accuracy and precision of commonly used methods for quantifying surgery-induced insulin resistance.
Insulin resistance develops in the perioperative setting and has an adverse influence on postoperative recovery and well-being. ⋯ Despite reasonably good linear correlations, the static tests grossly underestimated the degree of insulin resistance that developed in response to surgery.

Observational Study
Robotic assisted prostatic surgery in the Trendelenburg position does not impair cerebral oxygenation measured using two different monitors: A clinical observational study.
Robotic assisted prostatic surgery is frequently used because of its reduced side-effects compared with conventional surgery. During surgery, an extreme Trendelenburg position and CO2 pneumoperitoneum are necessary, which may lead to cerebral oedema, can potentially reduce brain perfusion and therefore could impair cerebral oxygenation. Cerebral oxygen saturation can be measured non-invasively using near-infrared spectroscopy (NIRS). ⋯ Both monitors showed a clinically irrelevant decrease in cerebral oxygen saturation of less than 5% over 4 h in a steep Trendelenburg position combined with CO2 pneumoperitoneum in patients undergoing robotic assisted prostatic surgery. This extreme positioning seems to be acceptable with regard to cerebral oxygenation.
