Overview

The MASCAN Score is a prospectively developed objective classification for difficult facemask ventilation. This prospective observational study aims to externally validate the MASCAN score in patients undergoing general anaesthesia for surgical procedures and to determine the influence of different approaches and techniques, such as the timing of neuromuscular blocking agents and manual versus controlled facemask ventilation. A secondary aim is to determine the diagnostic value of visual assessments of the capnography curve. Another secondary aim of the study is to compare the assessment of the first attempt success during tracheal intubation between the airway operator and an independent observer.

Eligibility

Inclusion Criteria:

  • Patients who are scheduled for surgery with general anesthesia and require facemask ventilation and tracheal intubation after induction of anesthesia
  • Patients aged 18 years or older
  • Provided informed consent

Exclusion Criteria:

  • Pregnant or breastfeeding woman
  • Required rapid sequence induction or other contraindications for facemask ventilation
  • Planned awake tracheal intubation
  • No consent given

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
