Multicenter Study Observational Study
Genetics and postsurgical neuropathic pain: An ancillary study of a multicentre survey.
Neuropathic pain following surgery could be a useful model for the study of the genetic mechanisms of peripheral neuropathic pain. ⋯ This is the first genetic association study specifically investigating the occurrence of persistent postsurgical neuropathic pain. Its results help target future research to better understand the mechanisms of peripheral neuropathic pain.

Multicenter Study Observational Study
Flow-controlled ventilation during ear, nose and throat surgery: A prospective observational study.
Flow-controlled ventilation (FCV) is a new mechanical ventilation mode that maintains constant flow during inspiration and expiration with standard tidal volumes via cuffed narrow-bore endotracheal tubes. Originating in manually operated 'expiratory ventilation assistance', FCV extends this technique by automatic control of airway flow, monitoring of intratracheal pressure and control of peak inspiratory pressure and end-expiratory pressure. FCV has not yet been described in a clinical study. ⋯ FCV achieves adequate PetCO2 levels with minute volume and Δp in the normal range. Tritube's high flow resistance may increase the likelihood of tube dislocations if the patient coughs. Although further evaluation is necessary, FCV provides a new option for short-term mechanical ventilation. The successful operation of FCV with narrow-bore tubes contributes to the armamentarium for airway management.
