Trial Outcomes & Findings for Comparing Hemodynamic Changes for Intubation With Shikani Intubating Stylet and Macintosh Laryngoscope (NCT NCT01271543)

NCT ID: NCT01271543

Last Updated: 2016-04-15

Results Overview

The double product was measured. The double product is calculated by multiplying the heart rate with the systolic blood pressure. It is also known as the rate pressure product and it is used to measure hemodynamic response.The double product is calculated from the values obtained preinduction, during intubation and after intubation.(5 minutes after intubation)The double products from each time point are averaged to get one mean double product value.

MacIntosh Group
Endotracheal Intubation : General anesthesia will be induced with fentanyl 1-2 mcg/kg, 2-3 mg/kg propofol and maintained with 50% air /50% oxygen and isoflurane. Neuromuscular blockade will be obtained with rocuronium 0.5 mg/kg. Laryngoscopy will be performed with MacIntosh laryngoscope blade size 3 for women and size 4 for men. Endotracheal intubation will be performed with an endotracheal tube of internal diameter of 7.0 mm l for female patients and 8 mm for males. Noninvasive blood pressure and heart rate will be recorded preinduction, preintubation, and every min for the first 5 min after successful intubation. The patients will be questioned post-operatively about symptoms of a sore throat, hoarseness, dysphonia or dysphagia in the Post Anesthesia Care Unit and again 24 hours after surgery.

PRIMARY outcome

Timeframe: Noninvasive blood pressure and heart rate will be recorded preinduction, preintubation, and every min for the first 5 min after successful intubation.

Population: double product (DP) of systolic blood pressure multiplied by heart rate

The double product was measured. The double product is calculated by multiplying the heart rate with the systolic blood pressure. It is also known as the rate pressure product and it is used to measure hemodynamic response.The double product is calculated from the values obtained preinduction, during intubation and after intubation.(5 minutes after intubation)The double products from each time point are averaged to get one mean double product value.
