The steep (40°) Trendelenburg position optimizes surgical exposure during robotic prostatectomy. The goal of the current study was to elucidate the influence of this patient positioning on cerebral blood flow and zero flow pressure (ZFP), and to assess the validity of different methods of evaluating ZFP. ⋯ Prolonged steep Trendelenburg positioning and CO(2) pneumoperitoneum does not compromise cerebral perfusion. ZFP and eCPP are reliable variables for assessing brain perfusion during prolonged steep Trendelenburg positioning.

We have developed a new bronchoscopy system with two independent lenses at the tip of the device. This enables measurement of object size using the principle of triangulation. This study was performed to assess the accuracy of this system. ⋯ We have confirmed that this new bronchoscopy system could provide relatively accurate quantitative data. This new system may be useful in the clinic to measure airway dimension and lesion sizes such as tumours.

Infection, whether localized or systemic, can be a relative contraindication to neuraxial anaesthesia. Data correlating neuraxial anaesthesia and the development of meningitis or epidural abscess in this setting are limited. ⋯ Based on clinical criteria, our findings suggest that the incidence of central nervous system infection after neuraxial anaesthesia in patients with infected hip and knee prostheses is low after neuraxial block.

An analysis of perioperative factors that were independently associated with survival up to 1000 days after scheduled colorectal adenocarcinoma resections in 314 patients. ⋯ Immediate perioperative care may have prolonged effects on postoperative survival. Specialized preoperative assessment clinics may reduce mortality after colorectal surgery.
