A 56-year-old woman with type 2 diabetes is being seen for a lengthy appointment for prosthodontic rehabilitation of her maxillary and mandibular arches.

Medical history

The patient is treated with a combination of levemir insulin (20 units hs) at bedtime and glimepiride (4 mg) in the morning. Her usual morning capillary blood glucose level is between 100 and 130 mg/dL. The only other medication she takes is levothyroxine (25 mcg qd).

Dental history and history of the current problem

The patient provided a lengthy history of dental care from the time of early childhood to the present. New carious lesions occurred frequently as a child, requiring amalgam restorations in the posterior regions and composite restorations in the anterior regions. Recurrent caries and failure of existing restorations required larger restorations and single crowns. Tooth #8 was lost due to trauma and a four-unit fixed partial denture (#7–10) replaces #8. The esthetics are poor. Endodontic treatment was needed for a number of teeth, and tooth #19 was lost as a result of a failed endodontic treatment. A three-unit fixed partial denture now replaces #19.

Many of the existing restorations demonstrate marginal deficiencies and recurrent caries. The patient is concerned with poor anterior esthetics. It was decided that a complete prosthodontic rehabilitation is required. Mild to moderate periodontitis is present. Periodontal surgery will be required to eliminate excessive probing depths before the final restorations are completed.

Treatment

An early morning appointment is scheduled to begin the crown preparations.

The patient is not NPO for the procedure, eats breakfast, and takes her normal dose of insulin and oral medication. During the procedure, the patient suddenly becomes confused, diaphoretic, and tachycardic. How should this situation be managed?
