Brief Summary
In our study, the investigators sought to answer the question of how the retroglossal pharyngeal areas measured after extubation of patients compare to baseline (before muscle relaxation) values. The investigators also investigated how these areas change as a function of TOF ratios measured at extubation, thus looking for a correlation between residual muscle relaxant effect and airway area.

Outcome Measures
Primary Outcomes (1)
The differences in retroglossal pharyngeal cross sectional areas (inspiration and exspiration) measured at different TOF values
The differences in retroglossal pharyngeal cross sectional areas (inspiration and exspiration) measured at different train of four TOF values, and changes in these values compared to (initial) retroglossae pharyngeal areas detected before administration of muscle relaxants. Areas are measured in pixels and the rate of reduction of areas is expressed as a percentage.
before intubation, after extubation of the trachea
Eligibility Criteria
Patients who receive a muscle relaxant (rocuronium bromide) for their operation to aid intubation and surgical exploration.
You may qualify if:
- Age: 18-65 years;
- ASA 1-3;
- BMI 18.5-25 (normal body weight);
- men/women in equal proportion;
- duration of surgeries at least ≥ 30 minutes;
- intervention requiring intratracheal intubation;
- patients are in a supine position.
You may not qualify if:
- diseases affecting neuromuscular function (myopathies, severe liver and kidney failure);
- drugs affecting neuromuscular function (magnesium, aminoglycosides);
- difficult airway, expected difficult intubation;
- pregnancy (pregnancy test for women of childbearing age to rule out pregnancy we finish);
- breastfeeding;
- acute surgery;
- COPD
- glaucoma
