Sedation and anesthesia
Many dental operations involve surgery. Surgery will often be preceded by some level of sedation, and anesthesia. Sedation is to overcome anxiety and fear, and to avoid unwarranted sudden movements by the patient in the chair. Anesthesia is needed to avoid pain. Local anesthesia is administered to a patient for removing pain sensations in a localized region. On the other hand, general anesthesia (GA) is used to avoid pain in the whole bodyand to keep the patient immobile for a considerable time.
General Anesthesia precautions
GA needs certain amount of preparation which includes assessment of allergic susceptibilities, and an empty stomach in addition to correct physical conditions, especially blood pressure and glucose level.Since the patient is totally unconscious when under GA and unable to communicate, his or her physical health parameters must be monitored continuously when under anesthesia. Anesthesia effect may linger on for some time and the patient must be restrained and observed till he or she recovers full control.
Surgeries under GA
General anesthesia is used only when necessary, that is when the patient is likely to feel unbearable pain or when he or she must remain immobile for the duration of a lengthy procedure. General anesthesia will normally be required in the following dental procedures:
· Orthodontic surgeries
· Complicated tooth extraction
· Impaction removal
· Excision of dental swellings
· Excision of maxillofacial tumors
· Root canal treatment procedures on multiple teeth
· Multiple teeth extractions
