Meta AnalysisPositive end-expiratory pressure and recruitment maneuvers during one-lung ventilation: A systematic review and meta-analysis.
It is unclear how positive end-expiratory pressure (PEEP) and recruitment maneuvers impact patients during one-lung ventilation (OLV). We conducted a systematic review and meta-analysis of the effect of lung recruitment and PEEP on ventilation and oxygenation during OLV. ⋯ Recruitment maneuvers and PEEP have physiologic advantages during OLV. The optimal use of PEEP is yet to be determined. The evidence is limited by heavy use of surrogate outcomes. Future studies with clinical outcomes are necessary to determine the impact of recruitment maneuvers and PEEP during OLV.

Multicenter Study Comparative Study Observational StudyEarly and late outcomes following aortic root enlargement: A multicenter propensity score-matched cohort analysis.
The safety and efficacy of aortic root enlargement (ARE) at the time of aortic valve replacement (AVR) remains unknown. The objective of this multicenter study was to compare AVR with ARE to AVR for early and late mortality and secondary safety outcomes. ⋯ The addition of ARE to isolated AVR can be safely performed to increase implanted prosthesis size without compromising early mortality. Additional studies with longer follow-up are necessary.
