The purpose of pharyngeal swab specimen collection is to take secretions from the pharynx and tonsils for bacterial culture or virus isolation. Use pharyngeal swab culture tube, alcohol lamp, matches, tongue depressor, flashlight. Step 1: Check the medical prescription, label the specimen container and bring the material to the patient's bedside.
2. Check the patient and explain the purpose and method of taking a pharyngeal swab for culture.
3. Ignite the alcohol lamp, ask the patient to open his mouth and make the "ah" sound, expose the throat, and wipe the secretions on both palatal arches and pharynx and tonsils with sensitive and gentle movements using the sterile long swab in the culture tube.
4. After taking, sterilize the test tube mouth on the flame of an alcohol lamp, and then insert the swab into the test tube and plug it tightly.
5. Send it for examination in time. Clinical significance If pathogenic bacteria are detected in sputum and pharyngeal swab secretions, it is considered a respiratory tract infection. It can be combined with other tests (X-ray fluoroscopy, ultrasound, etc.) to diagnose the site of respiratory tract infection. Common bacteria for respiratory tract infections are: Staphylococcus spp, S. pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus, Streptococcus, Pseudomonas aeruginosa, Escherichia coli, etc.
If Mycobacterium tuberculosis is cultured, it is tuberculosis. If yeast-like bacteria are cultured then consider if antibiotics were used improperly or in excess during the infection, and antibiotics should be stopped immediately and replaced with antifungal drugs, such as amphotericin B, ashwagandha, clotrimazole, etc.
