Co-induction technique refers to the use of a combination of medications to reach the desired therapeutic target. In the present study, the investigators examined the safety of a novel co-induction approach that relied on a simple timing and dosing alterations to the classical approaches of inhalational sevoflurane and propofol induction. The significance of this study is to find a reliable safe alternative method of induction that can provide optimal parameters,when compared to the classical methods of induction.
Co-induction technique refers to the use of a combination of medications to reach the desired therapeutic target. This technique is considered an approach that can be of a great benefit to patients with chronic medical illnesses and those who have moderate to high risk for general anaesthesia. In the present study, the investigators examined the safety of a novel co-induction approach that relied on a simple timing and dosing alterations to the classical approaches of inhalational sevoflurane and propofol induction. The significance of this study is to find a reliable safe alternative method of induction that can provide optimal parameters,when compared to the classical methods of induction. The investigators evaluated the time needed for laryngeal mask airway (LMA) insertion, number of LMA insertion trials, succession of LMA insertion, adverse events related to the airway, respiratory and cardiovascular systems, haemodynamic stability and satisfaction scores of enrolled patients.

Patients were given 1.5 mcg/Kg of fentanyl intravenously. two minutes after the fentanyl dose, a dose of 1.5 mg/kg of propofol slowly over 2 minutes.
Patients were given 1.5 mcg/Kg of fentanyl intravenously. two minutes after the fentanyl dose, patient received 8% inhalational sevoflurane through sealed plastic face mask at 8 L/min flow of oxygen.
Patients were given 1.5 mcg/Kg of fentanyl intravenously. two minutes after the fentanyl dose, patient received 4% sevoflurane through sealed plastic face mask at 8 L/min flow of oxygen for 2 minutes, followed by a dose of 0.75 mg/kg of propofol given slowly.

Intraoperative respiratory adverse events
The investigators recorded the occurrence of transient apnea intraoperatively, in addition to laryngeal spasm, coughing, gagging and increased salivation. The study chart included the documentation these common adverse events, the timing of occurrence, and the intervention required to manage these events.
Time frame: 8 months
Time for successful laryngeal mask airway insertion
The investigators assessed the time needed for LMA insertion. The timer was started upon giving the fentanyl, recording the time till successful insertion of laryngeal mask airway.
Time frame: 8 months
Blood pressure stability
The investigators recorded patients' blood pressure readings throughout the induction procedure.
Time frame: 8 months
Heart rate stability
The investigators recorded patients' heart rate throughout the induction procedure.
Time frame: 8 months
Changes in oxygen saturation
The investigators recorded patients' oxygen saturation throughout the induction procedure.
Time frame: 8 months
