A comparative study published in Acta Anaesthesiologica Scandinavica examined the analgesic efficacy of continuous serratus anterior plane block (SAPB) and thoracic epidural block for multiple rib fractures (MRF). The study found that both interventions significantly reduced pain levels, but the epidural block was more effective in reducing pain during movement within 2 hours after the block. However, the study raised questions about the methodology and results, including the use of a larger effect size for sample size calculation, variability in oxycodone consumption, and the limited assessment of patient satisfaction. The authors suggest that further studies are needed to confirm the effectiveness of SAPB as an alternative method for MRF analgesia when epidural block is contraindicated. No conflicts of interest or funding were reported. [Extracted from the article]

A study published in Acta Anaesthesiologica Scandinavica compared the effectiveness of continuous erector spinae plane block (ESPB) and continuous paravertebral block (PVB) for pain control following lung surgery. The study found that patients who received ESPB had higher pain intensity, a higher incidence of analgesia failure, and higher opioid consumption compared to those who received PVB. However, there are concerns about the study's methods and results, including inconsistent pain evaluation, inadequate pain control in the early post-operative period, and the clinical significance of the differences in pain scores and morphine consumption between the two groups. The authors caution that the study's findings should be interpreted with caution. [Extracted from the article]

An introduction is presented in which the editor discusses articles in the issue on topics including acute kidney injury (AKI) as a primary endpoint was defined using the Kidney Disease; categorizing preoperative serum albumin levels; and ASSESSMENT OF AKI within seven days after cardiac surgery.

With a great interest we read the recent article by Neuman et al1 assessing the association between mean systemic filling pressure analogue (Pmsa ) and acute kidney injury (AKI) following cardiac surgery. They showed that Pmsa as a surrogate for renal venous pressure was more closely associated with AKI than central venous pressure. As AKI has been significantly associated with morbidity and mortality in after cardiac surgery,2 their findings have potential implication. Other than the limitations described by authors in discussion, however, we noted several issues in their article on which we invited the authors to comment. [ABSTRACT FROM AUTHOR]
