Randomized Controlled Trial
Does fentanyl or remifentanil provide better postoperative recovery after laparoscopic surgery? a randomized controlled trial.
Fentanyl and remifentanil are widely used opioids in surgery, but it has not been evaluated whether the choice of opioids during surgery affects the patients' postoperative quality of recovery. Accordingly, we aim to compare postoperative recovery of fentanyl-based anesthesia with remifentanil-based anesthesia after laparoscopic surgery using the QoR 40 questionnaire (QoR-40). ⋯ Although the global QoR is higher in the fentanyl group by 20 points compared with remifentanil group, no significant differences revealed between the groups. Further studies with large numbers of subjects of the same gender are needed.

Management of a patient's body temperature is an important aspect of care that should be addressed by targeted temperature management (TTM). Often, non-invasive methods like forced-air blankets are used. Especially in the operating room this management may be a subsidiary and repetitive task requiring constant observation of the patient's body temperature and adaption using the limited set of available settings. Thus, automation of TTM is a feasible target to improve patient outcome and reduce caregiver workload. ⋯ Closed-loop TTM using non-invasive forced-air warming blankets was successfully tested in a porcine study with the proposed hardware interface and control algorithm. This automation can be beneficial for patient outcome and can reduce caregiver workload and patient risk in clinical settings. As temperature readings are most often available, existing devices like the 3M Bair Hugger can easily be expanded. However, even if clinical application is feasible, open questions regarding approval and certification of such automated systems within the current legal situation still need to be answered.

Meta Analysis
The association of body mass index with difficult tracheal intubation management by direct laryngoscopy: a meta-analysis.
Obesity is a serious disorder and may bring about many difficulties of perioperative management. A systematic review was conducted to assess the association between obesity and difficult intubation. ⋯ Obesity was associated with an increased risk of difficult intubation, difficult laryngoscopy and Mallampati score ≥ 3 in adults patients undergoing general surgical procedures. However, there were no association of obesity and risks of difficult intubation compared with non-obesity in the cohort studies and the elective tracheal intubation, no associated with an increased risk of difficult laryngoscopy in the sniffing position. Future analyses should explore the association of BMI and difficult airway.

Randomized Controlled Trial
Remote ischemic preconditioning for cardioprotection in elective inpatient abdominal surgery - a randomized controlled trial.
Perioperative myocardial injury (PMI) is common in elective inpatient abdominal surgery and correlates with mortality risk. Simple measures for reducing PMI in this cohort are needed. This study evaluated whether remote ischemic preconditioning (RIPC) could reduce PMI in elective inpatient abdominal surgery. ⋯ RIPC did not at reduce the incidence or severity of PMI in these general surgical patients using pre-determined definitions. PMI is nonetheless common and effective cardioprotective strategies are required.

Breast cancer is the second leading cause of cancer death in women. Surgery is the first line of treatment for breast cancer. Retrospective clinical studies suggest that the type of anesthesia administered during oncological surgery may influence patient outcome. ⋯ Prospective studies are in progress and will be finished within 5 years. The existing evidence is not sufficient to warrant changes to current anesthetic management. Further research is needed to clarify the mechanisms by which propofol affects cancer cells and the immune system.
