When a surgical procedure is performed under general anesthesia, the Airways are often secured With an endotracheal tube. Some patients experience sore throat thereafter. Studies have shown a reduction of these side effects when by use of muscle relaxants or a lidocain spray prior to the intubation. At Ostfold Hospital Trust, the investigators use one of the two methods or nothing. These methods will be studied systematically.
Heart rate and blood pressure rise during the intubation procedure. The investigators will also study the differences between the groups.

Endotracheal lidocaine spray prior to intubation
Drug: Lidocaine spray (2%)
Spraying trachea from 2 cm above the vocal cords and 5 cm down with a straw with multiple side holes
Other Name: Xylocain 2% Astra Zeneca
Muscle relaxant prior to intubation
Drug: Muscle Relaxant (Rocuronium)
After induction of anesthesia, the participants are given 0,6 mg/kg bodyweight intravenously.
Other Name: Esmeron MSD
No Muscle relaxant, no Lidocaine
'No Muscle relaxant, no Lidocaine Control group
Other: No Muscle relaxant, no Lidocaine
This group get general anesthesia without Rocuronium or Lidocaine
Other Name: Control group
- Sore Throat postoperative. Assessment of complaints and changes in complaints [ Time Frame: 2 h and 24 h after extubation ]Postoperative sore throat, described 2 h and 24 h after extubation. If the patient has sore throat or is hoarse, the complaint is assessed on a VAS (Visual Analogue Scale) 1 - 10.
- Intubation conditions directly after induction of anesthesia [ Time Frame: 90 sec. after established general anesthesia ]Describes the intubation conditions: Jaw relaxation, resistance to laryngoscopy blade, the position and movement of vocal cords, the movement of limbs and coughing. Each variable rates as excellent, good or poor. Intubation conditions are many variables described once and should not be divided into several outcomes.
- Hemodynamic parameters, change in HR (Heart Rate) is being assessed [ Time Frame: Prior to induction, then every second minute the next 15 minutes, thereafter every 15 minute until end of surgery (max. 2 h.) ]Describes changes in HR (Heart Rate)
- Hemodynamic parameters, change in BP (blood pressure) is being assessed [ Time Frame: Prior to induction, then every second minute the next 15 minutes, thereafter every 15 minute until end of surgery (max. 2 h.) ]Describes changes in BP(Blood Pressure)
