Improving fiberoptic intubation in the conscious patient using the new Janus mask

The right interface for the right patient in noninvasive ventilation: a systematic review

INTRODUCTION

Research in the field of noninvasive ventilation (NIV) has contributed to the development of new NIV interfaces. However, interface tolerance plays a crucial role in determining the beneficial effects of NIV therapy.

AREAS COVERED

This systematic review explores the most significant scientific research on NIV interfaces, with a focus on the potential impact that their design might have on treatment adherence and clinical outcomes. The rationale on the choice of the right interface among the wide variety of devices that are currently available is discussed here.

EXPERT OPINION

The paradigm "The right mask for the right patient" seems to be difficult to achieve in real life. Ranging from acute to chronic settings, the gold standard should include the tailoring of NIV interfaces to patients' needs and preferences. However, such customization may be hampered by issues of economic nature. High production costs and the increasing demand represent consistent burdens and have to be considered when dealing with patient-tailored NIV interfaces. New research focusing on developing advanced and tailored NIV masks should be prioritized; indeed, interfaces should be designed according to the specific patient and clinical setting where they need to be used.

Noninvasive ventilation during left atrial appendage closure under sedation: Preliminary experience with the Janus Mask

Background:

Percutaneous left atrial appendage occlusion (LAAO) is indicated in subjects with atrial fibrillation who cannot receive oral anticoagulants. This procedure requires transesophageal echocardiography guidance and is usually performed under general anesthesia. The Janus Mask is a new device designed to allow upper endoscopic procedures during noninvasive ventilation (NIV).

Aims:

This study aims to assess the possibility of performing LAAO under sedation and NIV.

Setting:

Cardiac electrophysiology laboratory.

Design:

Case–control study.

Materials and Methods:

Data from 11 subjects undergoing LAAO under sedation and NIV with the Janus Mask were retrospectively collected. Procedure duration, outcomes, and physicians' satisfaction were compared with those of 11 subjects who underwent LAAO under general anesthesia in the same period.

Statistical Analysis:

Univariate analysis and analysis of variance for between-groups comparison.

Results:

The 11 subjects treated with sedation experienced a good outcome, with a high degree of satisfaction from the medical team. An increase in arterial partial pressure of carbon dioxide in the Janus group (45 [43–62] mmHg vs. 33 [30–35] mmHg in the general anesthesia group, P < 0.001) led to a transient pH decrease 45 min after the beginning of the procedure (7.30 [7.18–7.36] vs. 7.40 [7.39–7.46], P = 0.014). No differences in arterial partial pressure of oxygen, FiO₂, and hemodynamic parameters were observed. The subjects' conditions at discharge from the recovery room were comparable. No difference in procedure duration was registered.

Conclusions:

LAAO procedure under sedation and NIV through the Janus Mask is safe and feasible. This strategy might represent a valuable alternative to manage such a compromised and fragile population.
