Intravenous sedation is a carefully controlled technique of intravenous administration of one or more drugs, which leads to a certain degree of depression of the central nervous system. This procedure enables dental procedures with minimal physiological and psychological stress for the patient. Conscious sedation is achieved, the patient remains awake, preserves reflexes, and can respond to verbal commands. The sedation procedure takes place in three phases, which include preoperative procedures and preparation, supervision during sedation and postoperative procedures. Before performing a dental procedure with patient under sedation, it is necessary to have a preoperative conversation with the patient, clinical examination, additional laboratory tests if the patient's health condition requires it. It is also mandatory for the patient to sign consent for sedation. The patient is then instructed on preoperative fasting. Before the procedure, it is necessary to measure blood pressure, pulse, body weight and height, and to determine the position of venous catheter. During conscious sedation, it is obligatory to monitor, i.e. supervise the patient’s vital functions to recognize pathological changes in physiological processes as early as possible and to prevent possible complications as early as possible. Thus, intravenous sedation is one of the safest sedations. Monitoring should be continued after the completion of the dental procedure until the patient is complete recovered. The recovery is shorter than after oral, intramuscular or rectal sedation. The patient is discharged home in full consciousness, fully oriented with stable vital functions accompanied by a responsible adult. Intravenous sedation is becoming an increasingly used method of sedation in dental practice due to the rapid onset of sedation, short duration of action and the possibility of deepening the sedation if the desired level is not achieved.
