Which of the following is a technique for the aspiration of soft tissues?

a. Indications: cellulitis that does not respond to initial standard treatment, recurrent cellulitis or abscesses, immunocompromised patients in whom it is necessary to recover the causal microorganism, which could condition antimicrobial treatment.
b. Complications: pain, infection, bleeding.
c. Technique: choose the site to aspirate at the point of maximum inflammation (greater chances of recovering the causal agent than if the edge or center of the erythema is aspirated).
d. Fill a tuberculin syringe with 0.1-0.2 ml of sterile non-bacteriostatic saline solution, and attach the needle.
e. Using an 18 or 20 gauge needle (22 gauge for facial cellulitis), penetrate to the appropriate depth, inject the saline solution, aspirate the fluid, and apply negative pressure while removing the needle.
f. Send the aspirated fluid for Gram staining and cultures. If no fluid is obtained, the needle can be rubbed on an agar plate. Consider using stains for acid-resistant bacilli and fungi in immunocompromised patients.
a. I, II, and III are correct.
b. II, III, and IV are correct.
c. III, IV, and V are correct.
d. IV, V, and VI are correct.
