INTRODUCTION: Sustaining spontaneous air flow (SV) beneath complete intravenous anesthesia (TIVA) with out an endotracheal tube offers uninterrupted and unobstructed surgical entry for suspension microlaryngoscopy (SML). This examine describes the strategy and end result of adults who underwent SML beneath tubeless TIVA-SV.
METHODS: Retrospective assessment of adults who underwent SML between June 2014 and September 2016 utilizing TIVA-SV with out an endotracheal tube.
RESULTS: Sixty-six circumstances in 36 sufferers have been included with imply age of 50.6 years and 52.7% have been feminine. Airway pathology included 41.6% subglottic or tracheal stenosis, 19.four% laryngeal lesion or mass, 16.7% glottic stenosis, 13.9% recurrent respiratory papilloma, and eight.three% supraglottic stenosis. Anesthesia was mostly supplied by steady infusion of propofol and remifentanil (57.6%). Roughly half (53%) of circumstances obtained superior laryngeal nerve block. Common operative time was 72.9 minutes (vary, 27-166 minutes). Eight circumstances required supplemental air flow: 6 circumstances required transient endotracheal air flow or masks air flow, and a couple of circumstances have been transformed to various air flow.
CONCLUSIONS: Complete intravenous anesthesia is a beautiful various to conventional endotracheal tube intubation, jet air flow, or intermittent apneic air flow for grownup SML. Throughout episodes of hypoventilation or desaturation, endotracheal air flow, masks air flow, or jet air flow can successfully get well oxygenation.
