Registration Number
NCT05725031
Lead Sponsor
Ain Shams University
Brief Summary

This trial will study if ephedrine pretreatment before low doses of rocuronium (0.6 or 0.8 mg/kg) would provide similar intubating conditions as with the high dose of 1.2 mg/kg in patients undergoing RSII.

Primary Outcome Measures
NameTimeMethod
Intubation conditionsafter 60 seconds of rocuronium administration

Evaluation of intubation conditions after rapid sequence induction using rocuronium 0.6 or 0.8 mg/kg with ephedrine pretreatment, compared with 1.2 mg/kg, according to the criteria of the Good Clinical Research Practice (GCRP) in pharmacodynamic studies of NMBAs (Fuchs-Buder et al., 2007), which assess each of the following variables for their qualities described as: (excellent, good, poor)

* ease of laryngoscopy (easy, fair, difficult)

* vocal cords position (abducted, intermediate, closed)

* reaction to tracheal tube insertion and cuff inflation (coughing: none, slight, vigorous)

The 3 variables will be combined to describe intubation conditions as:

* Excellent: if all qualities are excellent

* Good: if all qualities are either excellent or good

* Poor: if there is a single poor quality

Secondary Outcome Measures
NameTimeMethod
Mean arterial pressureevery minute of the first 5 minutes of intubation

Following up the mean arterial pressure by noninvasive blood pressure monitoring

Heart rateevery minute of the first 5 minutes of intubation

Following up the heart rate on the monitor
