RESUMO
PURPOSE OF REVIEW: This review is to discuss the role of autophagy in the critically ill patient population. As the understanding of autophagy continues to expand and evolve, there are certain controversies surrounding whether intensivist should allow the benefit of autophagy to supersede gold standard of insulin therapy or early nutritional support. RECENT FINDINGS: The review is relevant as the current literature seems to support under-feeding patients, and perhaps the reason these studies were positive could be prescribed to the mechanisms of autophagy. It is well understood that autophagy is a physiologic response to stress and starvation, and that the inducible form could help patients with end-organ dysfunction return to homeostasis. SUMMARY: The jury is still out as to how autophagy will play into clinical practice as we review several gold standard therapies for the critically ill.

BACKGROUND: Our thoracic enhanced recovery program (ERP) decreased the use of postoperative morphine equivalents and hospital costs 1 year after implementation at our tertiary center. The sustainability and potential increasing benefit of this program were evaluated. METHODS: From 2015 to 2021, we prospectively analyzed the outcomes of patients who underwent elective pleural, pulmonary, or mediastinal operations at our institution. Patients were separated on the basis of the incision (video-assisted thoracoscopic surgery [VATS] or thoracotomy). The ERP protocol was initiated on May 1, 2016, and includes preoperative education, carbohydrate loading, opioid-sparing analgesia, conservative fluid management, protective ventilation, and early ambulation. Outcomes of patients before (2015, pre-VATS and pre-thoracotomy) and after (May 1, 2016, to December 31, 2021, ERP-VATS and ERP-thoracotomy) ERP implementation were compared. RESULTS: The cohort included 1079 patients (pre-ERP era, n = 224 [21%]; ERP era, n = 855 [79%]). There was a median reduction of 1.5 hospital days per patient for ERP-thoracotomy and 1 hospital day per patient for ERP-VATS. Median postoperative morphine equivalents decreased in both groups (125 vs 45 mg, in ERP-thoracotomy; 84 vs 23 mg, ERP-VATS; P < .001), as did total admission cost ($32,118 vs $23,775, ERP-thoracotomy; $17,367 vs $11,560, ERP-VATS; P < .001). Median total fluid balance during the hospital stay decreased significantly. Rates of postoperative atrial fibrillation and urinary retention decreased across both subgroups. CONCLUSIONS: ERP for thoracic surgery is sustainable and has been demonstrated to improve patient outcomes, to decrease opioid use, and to lower hospital costs. Therefore, it has the potential to become the standard of care.
