Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The trial will be done to determine the impact of a barrier enclosure, COVID (coronavirus disease -19) barrier box on endotracheal intubation attempts, and duration. This study will be a prospective, open-label, randomized controlled trial. A total of 100 patients scheduled for elective surgery will be randomly assigned in two groups (intervention group and control group). Participating attending anesthesiologists will intubate the intervention group patients with COVID barrier box and the control group patients without the box. The anesthesiologists and the intervention group patients will be surveyed about their perception after the surgery. The result of this study will help in decision making about using COVID barrier box to minimize the viral transmission from patients to healthcare workers during the pandemic.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Purpose:

To assess the time to tracheal intubation (TTI) and first-pass success rate for attending anesthesiologists intubating with COVID-related modifications with or without the use of a COVID barrier box.

Hypothesis:

Using a COVID barrier box for tracheal intubation with COVID-related modifications for attending anesthesiologists would be prolonged compared to not using one.

Justification:

Tracheal intubation is a high-risk time point for attending anesthesiologists to contract COVID. This risk can be minimized by using a proprietary barrier enclosure, COVID barrier box covering a patient's head and neck during intubation. It is crucial to estimate the intubation time and first-pass success rate of using a COVID barrier box for introducing it to intubate critically ill COVID patients. The finding of this study can lead to a ground-breaking measure to minimize viral transmission to healthcare workers during the pandemic.

Objectives:

The primary objective of the study is to determine the TTI as measured by an observer. The secondary objectives are to assess the first-pass success rate, the total time of airway manipulation, as well as anesthesiologists' perception of intubation difficulty, and patients' satisfaction.

Research Design:

This study will be a prospective, open-label, randomized controlled trial. Consented eligible patients will be randomly allocated in a 1:1 ratio to intervention or control groups. A computer-generated sequence of random numbers will be used to randomize patients between groups. Consented eligible attending anesthesiologists will use COVID barrier box for intubating the intervention group but not for the control group. Each anesthesiologist will perform one practice intubation on manikins with the COVID barrier box before initiation of the study. The locally instituted COVID-related modifications will be in place during the practice intubation and intubations during surgery for both groups. A third party observer will monitor intubation time. All attending anesthesiologists and intervention group patients will undertake a post-survey.

Statistical Analysis:

A total of 100 patients with 50 in each group will be included in the study to ensure 99% power to detect a clinically significant TTI difference. Data distribution will be assessed using the Shapiro-Wilk and D'Agostino tests. Time outcomes will be analyzed using t-test or Mann-Whitney test. The first-pass success rate and categorical data about intubation difficulty and patient satisfaction will be analyzed using Fisher's Exact test.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This will be a prospective, open-label, randomized controlled trial in which patients will be randomly allocated to two study groups on a 1:1 basis into:

1. COVID-19 barrier box Intervention group: Anesthesiologists will use a COVID barrier box during intubation.
2. Control group: Anesthesiologists will not use a COVID barrier box during intubation. Standard intubation procedures will be followed for intubation.

A block randomization strategy, using a computer-generated sequence of random numbers, will be used. Randomization will occur preoperatively if consented patients meet the eligibility criteria and provide informed consent.
