Case Reports
Small doses of epinephrine prolong the recovery from a rocuronium-induced neuromuscular block: a case report.
During anaesthesia it is not uncommon to administer epinephrine in patients blocked by non-depolarizing muscle relaxants. However, there are few reports on possible interaction of epinephrine with neuromuscular transmission in humans. ⋯ In this case reported here small doses of intravenously administered epinephrine markedly prolonged a rocuronium-induced neuromuscular block. Given the widely used co-administration of epinephrine and muscle relaxants possible adrenergic interference with neuromuscular transmission would have implications for daily anaesthetic practice.

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.
