Heart-Protective Mechanical Ventilation in Postoperative Cardiosurgical Patients
CONCLUSIONS: In postoperative cardiosurgical patients, MV with Vt 6 ml × kg-1 and PEEP 10 cm H2O is characterized by worsened oxygenation and elimination of CO2 and a less favorable hemodynamic profile than ventilation with Vt 10 ml × kg-1 and PEEP 5 cmH2O. New and Noteworthy. (i) Patients after CABG may be especially sensitive to low tidal volume and increased PEEP as it negatively affects hemodynamic profile by means of the right heart preload decrease and afterload increase. (ii) Mechanical ventilation settings aiming to minimize mean airway pressure reduce the negative effects of positive inspiratory pressure and are favorable for hemodynamics.PMID:33859842 | PMC:PMC8009731 | DOI:10.1155/2021/6617809
To investigate the role of preoperative hematologic indices (neutrophil-lymphocyte ratio [NLR], platelet-lymphocyte ratio [PLR], systemic immune-inflammation index [SII; neutrophil × platelet/lymphocyte) in predicting short-term outcomes after off-pump coronary artery bypass grafting (OPCABG).
ConclusionIn a center with expertise in valve ‐sparing procedures, ARREAA is a reasonable option in the surgical management of AAAD in selected patients. This technique stabilizes the aortic annulus and preserves root anatomy for durable outcomes.

Conclusion Among patients with severe degenerative aortic stenosis, vitamin D deficiency is common. We found a significant association between left ventricular wall thickness and vitamin D levels, suggesting a potential role of this hormone in modulating hypertrophic remodelling in these patients. However, future larger studies are certainly needed to confirm our findings and to define their prognostic implications.

Conclusions: Carotid endarterectomy continues to prove its safety in carotid artery stenosis patients. Continuous cerebral oxygenation monitoring is indispensable for carotid surgery. Despite discrepancies in surgical techniques, we believe that "one fits all strategy: general anesthesia, conventional endarterectomy without patch plasty, never shunter and always NIRS monitorization" may be used safely in patients undergoing carotid endarterectomy.

Conclusions: In CABG patients with a narrow QRS complex, preoperative intermediate prolonged QRS is an independent predictor of all-cause mortality in long-term follow-up. PMID: 33014085 [PubMed]
Conclusions: Multimodal low-opioid anesthesia during coronary artery bypass surgery with artificial blood circulation allows one to ensure adequate analgesia and avoid the intraoperative usage of routine doses of fentanyl, as indicated by the absence of hemodynamic and endocrine-metabolic changes.
