Perioperative visual loss (POVL) after nonocular surgery is a rare but unexpected event and represents a devastating complication. It is most often associated with cardiac, spinal as well as head and neck surgery. The etiology of POVL remains incompletely understood. ⋯ However, the risk factors for any given patient or procedure may vary. The underlying specific pathogenesis of these neuro-ophthalmic complications remains unknown and physicians should be alert to the potential for loss of vision in the postoperative period. This review updates readers on the incidence, suspected risk factors, diagnosis and treatment of POVL in the setting of nonocular surgery.

Randomized Controlled Trial
[Tonsillotomy and adenotonsillectomy in childhood. Study on postoperative pain therapy].
The primary aim of this study was to determine whether the combination of i.v. ketoprofen and i.v. paracetamol provides superior postoperative analgesia in children undergoing adenoidectomy or tonsillotomy compared to either drug alone. The secondary goal was to assess the time until rescue analgesia was needed, propofol requirements and the incidence of vomiting and time of discharge from the postanaesthesia recovery unit (PARU). ⋯ The combination of i.v. paracetamol and i.v. ketoprofen provides superior postoperative analgesia compared to the single use of paracetamol.

In the case presented an intravenous line for large volume infusion rates was to be placed in a patient with an aortic aneurysm during clinical preoperative care. After a high-flow catheter had been placed without any problems retraction of the guide wire was found to be impossible. Computer tomography revealed that the reason was a kink in the catheter resulting in the guide wire being nipped off. Fortunately both catheter and guide wire could be removed completely without any further complications.

Despite improved strategies in the treatment of polytraumatized patients the mortality rate of severely injured patients remains high. Thus, worldwide 5 million patients die due to trauma or trauma-related complications each year. As the majority of early trauma-related deaths are attributed to or caused by exsanguination the prevention and treatment of coagulopathy is of paramount significance. ⋯ Under consideration of new clinical studies, an updated version of the original publication from 2007 has recently been published. Based on a systematic review of published literature the recommendations were formed according to "Grading of Recommendations Assessment, Development and Evaluation" (GRADE). This publication summarizes the main recommendations with a special emphasis on revisions and new aspects.
