Remote ischemic conditioning (RIC) has the potential to benefit graft function following kidney transplantation by reducing ischemia-reperfusion injury; however, the current clinical evidence is inconclusive. This meta-analysis with trial sequential analysis (TSA) aimed to determine whether RIC improves graft function after kidney transplantation. ⋯ In this meta-analysis with trial sequential analysis, RIC did not lead to a significant reduction in the incidence of DGF after kidney transplantation. Nonetheless, RIC demonstrated a positive correlation with 3-month eGFR. Given the limited number of patients included in this study, well-designed clinical trials with large sample sizes are required to validate the renoprotective benefits of RIC.

Pregnancy is associated with an increased risk of pulmonary aspiration during general anaesthesia, but the incidence of this complication is not well defined. ⋯ In conclusion, in this obstetric surgery patient population at risk for pulmonary aspiration, supraglottic airway devices were used in approximately 60% of cases. Yet, no aspiration event was detected with either a supraglottic airway or endotracheal intubation.

The exact mechanisms and the neural circuits involved in anesthesia induced unconsciousness are still not fully understood. To elucidate them valid animal models are necessary. Since the most commonly used species in neuroscience are mice, we established a murine model for commonly used anesthetics/sedatives and evaluated the epidural electroencephalographic (EEG) patterns during slow anesthesia induction and emergence. ⋯ Our results showed substance-specific changes in EEG patterns during slow anesthesia induction. These patterns were partially identical to previous observations in humans, but also included significant differences, especially in the low frequencies. Our study emphasizes strengths and limitations of murine models in neuroscience and provides an important basis for future studies investigating complex neurophysiological mechanisms.

Randomized Controlled Trial
Role of preoperative zinc, magnesium and budesonide gargles in Postoperative Sore Throat (POST) - a randomised control trial.
Post-operative sore throat (POST) has an incidence ranging from 21 to 80%. To prevent the development of POST, several pharmacological measures have been tried. Aim of this study was to compare the efficacy of preoperative zinc, magnesium and budesonide gargles in reducing the incidence and severity of POST in patients who underwent endotracheal intubation for elective surgeries. ⋯ Magnesium, zinc and budesonide have an equivocal effect in the prevention of POST at different time points. The incidence of sore throat increases significantly in surgeries lasting more than two hours if magnesium or budesonide have been used as premedicant. Duration of surgery is an independent predictor for POST.

Patients often desire involvement in anesthesia decisions, yet clinicians rarely explain anesthesia options or elicit preferences. We developed My Anesthesia Choice-Hip Fracture, a conversation aid about anesthesia options for hip fracture surgery and tested its preliminary efficacy and acceptability. ⋯ Use of clinical decision aids may increase shared decision-making; further testing is warranted.
