Discharge criteria will be assessed as postanaesthesia discharge score hourly. When the patients are fully recovered, defined as an OAA/S score of 5 and the postanaesthesia score is more than 9, they are fit for discharge. Satisfaction evaluation of sedation will be graded by the patients on NRS in satisfaction patient. They will be questioned on whether they think that they have received an adequate amount of sedation, too little or too much, whether they are relaxed and whether they will undergo the same procedure again.
