The efficacy of the erector spinae plane block (ESPB) has been demonstrated in several meta-analyses and it is increasingly being used in clinical practice. However, its mechanism of action is still not fully elucidated. Although initial anatomical studies have suggested the spread of the injectate into the paravertebral space as the main mechanism of action, more recent studies have not consistently demonstrated this. This systematic review was conducted to determine the overall proportion and extent of injectate spread following a thoracic ESPB. ⋯ Based on this study, the thoracic ESPB consistently led to injectate spread into the ESP compartment but less reliable spread into the PVS, ES and ICS compartments. There is also preliminary evidence that an increased time to assessment may be associated with an increased spread of injectate into the PVS.

Acute kidney injury (AKI) is a serious complication in postoperative ICU patients. The incidence of AKI varies substantially based on the type of surgery and definition used. This study focuses on the incidence of AKI in postoperative ICU patients using full KDIGO criteria and related outcomes regarding to different types of surgery. ⋯ AKI based on full KDIGO criteria is very common in postoperative ICU patients and it is associated with stepwise increase in 28-days mortality.

Randomized Controlled Trial
Recurarization with magnesium sulfate administered after two minutes sugammadex reversal: A randomized, double-blind, controlled trial.
The current study tested the hypothesis that magnesium sulfate after reversal with sugammadex causes recurarization. ⋯ Single-dose magnesium sulfate led to a normalized train-of-four ratio < 0.9, 2 min after recovery from rocuronium-induced deep and moderate neuromuscular blockade using sugammadex. Additional sugammadex reversed prolonged recurarization.
