PharmacologyDog bite: Augmentin. This antibiotic is bacteriocidal for the range and spectrum of human and animal bite pathogens including Staphylococcus species and Pasteurella multocida.
Rhinnoplasty
Facial CosmeticsThe transfixion and hemitransfixion incision provide access to the caudal septum in endonasal rhinoplasty. The complete transfixion incision separates the medial crura from the septum. The hemitransfixion incision is only made on one side, and usually stops short of the anterior nasal spine, preserving tip support. The nasal dorsum is not approached with the transfixion
Eyelid Reconstruction
Oral & Maxillofacial Surgery25% – closed primarily 25-50% – local tissue advancement >50% – flap or skin graft which replaces both the anterior and posterior lamella Manage 40% avulsion of upper eyelid o Full thickness skin graft from opposite upper lid is preferred due to similar skin thickness, color, texture and availability with minimal donor site morbidity.

Ventilation
RespiratoryA number of factors play a role in controlling alveolar ventilation. The central areas of inspiratory and expiratory control lie in the medulla, and primarily respond to increases in hydrogen ion concentration in the cerebrospinal fluid. Although hydrogen ion concentration is the most important stimulus to the chemosensitive centers in the medulla, these ions cross
Salivary Glands
AnatomySalivary Glands: Anatomy, Function, and Clinical Significance Salivary glands play a critical role in oral health, digestion, and protection of the teeth and oral tissues. These glands are responsible for producing saliva, an essential fluid that aids in chewing, swallowing, digestion, lubrication of oral tissues, and antimicrobial defense. Disorders of the salivary glands are common
Pediatric Upper Respiratory Infections (URI)
AnesthesiaIt is likely that this child has an upper respiratory infection (URI). Signs of an URI include fever, fatigue, loss of appetite, productive cough, and thick nasal discharge. Children withURI have an irritable airway and are at increased risk for laryngospasm, bronchospasm, postintubation croup, pneumonia, and episodes of desaturation. Bronchial hyperreactivity may last 4 to

Anesthesia Considerations in Geriatrics
AnesthesiaGeriatric increases in anesthetic sensitivity is most closely associated with:a decrease in levels of neurotransmitters and receptors in different regions of the brain. In the elderly, there is a reduction in the number of neurons; this is matched by an decrease in the cerebral metabolic rate. The cerebral metabolic rate is directly related to the
