PSA injection should not be given in which condition?

PSA injection should not be given in which condition?

• A. If patient has hemophilia
• B. If patient is allergic to latex
• C. If patient has diabetes
• D. If patient has hypertension

Answer: (A)

The key idea is recognizing a bleeding risk with PSA anesthesia. The posterior superior alveolar block is given near a dense network of vessels in the maxillary tuberosity area, so any needle entry can cause a hematoma. In a person with a bleeding disorder like hemophilia, even minor trauma can lead to uncontrolled bleeding and a hematoma that may be difficult to manage in the infratemporal space. That makes this block contraindicated unless coagulation status is corrected or a hematologist is involved. latex allergy can be managed by using latex-free equipment, and diabetes or hypertension are not inherent contraindications to this block, though overall medical management should be optimized.
