Oral SurgeryFor a 75-year-old, 100-pound woman requiring multiple extractions, 10 mg of diazepam is sufficient for premedication. Elderly patients and those with lower body weight require reduced dosages due to altered drug metabolism and increased sensitivity. The goal is anxiolysis without excessive sedation, and 10 mg provides adequate premedication while minimizing risks of respiratory depression or prolonged sedation.

Oral SurgeryIf one expects a long surgical procedure and a general anaesthetic to be administered, intubation with individually selected anaesthetic agent is indicated.

Oral SurgeryCervicofacial emphysema is a condition where air becomes trapped in the soft tissues of the face and neck. It is usually a benign, self-limiting condition that resolves on its own without specific intervention.

Oral Surgery
The coronoid process can become impinged due to
displacement of the zygomatic arch, restricting the movement of the mandible and
causing trismus (difficulty in mouth opening).

Oral SurgeryPatients under steroid therapy requiring extraction of infected teeth need antibiotic premedication. Chronic steroid use suppresses immune function, increasing infection risk and impairing wound healing. Prophylactic antibiotics help prevent post-operative infections and complications in these immunocompromised patients, especially when extracting already infected teeth.

Oral SurgeryThe risk associated with open reduction and internal fixation (ORIF) in older patients is not solely due to their age or increased bone density. It's important to consider their overall health, including potential comorbidities and reduced healing capacity. The risks might be higher due to factors like poor bone quality, increased surgical time, and the potential for complications such as infection and nonunion.

Oral SurgeryExtraction during acute infection helps drainage and relieves pain when proper antibiotics are given adequately. The extraction creates a drainage pathway, reducing pressure and bacterial load. However, this should only be done with appropriate antibiotic cover and when the infection is localized.

Oral SurgeryLidocaine is an example of an amide.

Oral SurgeryToxic reactions to local anesthetics typically progress from a stimulatory phase to a depressive phase. The stimulatory phase is characterized by signs such as nervousness, tremors, twitching, and possibly choreiform movements. The subsequent depressive phase involves central nervous system depression, which can lead to respiratory depression, hypotension, and ultimately, shock.
