Abstract

Purpose/Background:This scoping review explores the effectiveness of adaptive support ventilation (ASV) compared to conventional ventilation modes in reducing postoperative extubation times in adults undergoing general anesthesia with ventilatory support. Ventilator weaning is a critical determinant of recovery and outcomes in intensive care settings. ASV, a closed-loop ventilation mode, automatically adjusts ventilator parameters based on patient-specific respiratory mechanics and demand to optimize the weaning process. Although promising, evidence regarding ASV’s effectiveness remains inconsistent across different patient populations and surgical contexts.

Methods: A systematic literature search was conducted from August 2023 to December 2024 across PubMed, CINAHL, Medline, JAMA, and Google Scholar. Studies were eligible if published in English, focused on adult patients requiring ventilatory support, and reported extubation time as a primary or secondary outcome. Eight high-quality studies, including randomized controlled trials and systematic reviews, were selected after critical appraisal. Extracted data included extubation time, intubation duration, postoperative complications, ventilator adjustments, and ICU or hospital length of stay.

Results: Of the eight studies reviewed, five reported that ASV reduced extubation times, and three showed shorter intubation durations. All studies demonstrated a reduction in postoperative complications and fewer ventilator adjustments. Three studies associated ASV with decreased ICU or hospital stays. Variability in extubation outcomes appeared related to patient characteristics and clinical practices.

Implications for Nursing Practice: ASV has the potential to enhance patient outcomes by expediting weaning, reducing complications, and shortening ICU stays. Standardized protocols are needed to optimize ASV implementation across diverse clinical settings.
