Meta AnalysisErector spinae plane block versus paravertebral block for postoperative pain management in thoracic surgery: a systematic review and meta-analysis.
The 2018 guidelines for enhanced recovery in thoracic surgery recommend paravertebral block (PVB) for postoperative pain management. However, recent studies demonstrate that erector spinae plane block (ESPB) achieves similar postoperative pain control with reduced block-related complications. ⋯ Compared with PVB, ESPB is safe and demonstrates no clinically significant differences in pain management after thoracic surgery.

Accidental or surgically induced thoracic trauma is responsible for significant pain that can impact patient outcomes. One of the main objectives of its pain management is to promote effective coughing and early mobilization to reduce atelectasis and ventilation disorders induced by pulmonary contusion. ⋯ In this narrative review, we propose to detail systemic and regional analgesia techniques to minimize postoperative pain, while reducing transitional pain, surgical stress response and opioid side effects. We provide the reader with practical recommendations based on both literature and clinical practice experience in a referral level III thoracic trauma center.

Preoperative risk stratification for hepatectomy patients can aid clinical decision making. The objective of this retrospective cohort study was to determine postoperative mortality risk factors and develop a score-based risk calculator using a limited number of preoperative predictors to estimate mortality risk in patients undergoing hepatectomy. ⋯ Development of risk calculators may potentially allow surgical and anesthesia providers to provide a more transparent plan to support patients planned for hepatectomy.

Sex-Specific Associations Between Preoperative Hemoglobin and Outcomes After Major Noncardiac Surgery: A Retrospective Cohort Study.
Preoperative anemia is an established risk factor for morbidity and mortality after surgery. Men and women have different hemoglobin concentrations and are at different risks of postoperative complications. However, sex-stratified analysis on the association between preoperative hemoglobin and outcomes after noncardiac surgery has been limited in previous studies. ⋯ Low preoperative hemoglobin was associated with a higher risk of complications or mortality after elective noncardiac surgery in both men and women. No differences in the strength of associations between sexes were found. Further studies are needed to assess whether these associations are linear or there are sex-specific thresholds of preoperative hemoglobin concentrations below which postoperative risks begin to increase.

Hyperoxia Increases Kidney Injury During Renal Ischemia and Reperfusion in Mice.
Renal ischemia and reperfusion (IR) contribute to perioperative acute kidney injury, and oxygen is a key regulator of this process. We hypothesized that oxygen administration during surgery and renal IR would impact postoperative kidney function and injury in mice. ⋯ In this controlled preclinical study of oxygen treatment during renal IR surgery, hyperoxia and hypoxia impaired renal function, increased renal injury, and impacted expression of genes that affect mitochondrial biogenesis and antioxidant response. These results might have implications for patients during surgery when high concentrations of oxygen are frequently administered, especially in cases involving renal IR.
