NCT06968377

Brief Summary

The aim of this study is to test a bubble-like dome (made of clear plastic) being placed over patients' heads during surgery as a tool to prevent the spread of germs through the air in hospitals. The researchers are interested in the following outcomes:

  • How the device affects the patients' experience of surgery.
  • The impact of the device on how long it takes to place a breathing tube, blood pressure, heart rate and oxygen levels of the patient. Researchers will compare the outcomes across patients using the device and patients not using the device. This will be done by randomly (by chance) assigning participants undergoing surgery to group 1 (using the bubble-like dome device) or group 2 (not using the device). Participants will:
  • Tell the researchers or your anesthesia doctor about any problems that you experience that you think might be related to participating in the study.
  • Fill out a 10-minute survey regarding your experience with the dome after surgery.
  • If you did not try the dome before going to sleep, you will be able to watch a video of the dome in use and answer questions based on the video
  • Be video recorded with your time with the dome.

Outcome Measures

Primary Outcomes (1)

  • Duration of time needed to place an airway.

    Difference in means of airway times with and without the device present.

    Day of surgery (intubation)

Secondary Outcomes (14)

  • Mean delta ETCO2

    For 5 min pre- and post- intubation

  • First pass intubation success rate (%)

    Day of Surgery - intubation

  • Patient Body Mass Index

    Day of Surgery

  • Blood Pressure

    Every 1 minute during surgery (at least 2 measures taken prior to device deployment and 2 prior to induction)

  • Mean nadir ETO2 (%)

    For 5 min pre- and post- intubation

  • +9 more secondary outcomes

Study Arms (2)

Dome

EXPERIMENTAL

The device is a large, bubble-like dome made of clear plastic through which doctor and nurse can care for the patient during surgery.

Device: A novel airborne pathogen containment device.

No dome

NO INTERVENTION

Standard care during surgery.

Interventions

The dome is placed over the patient's head during the full duration of a surgery (intubation and extubation included) as a method of preventing infection transmission through airborne aerosols throughout a hospital.
