percutaneous epididymal sperm aspiration

aspiration

(as?pi-ra'shon) [ aspirate] 1. Drawing in or out by suction. Foreign bodies may be aspirated into the nose, throat, or lungs on inspiration. 2. Withdrawal of fluid from a cavity by suctioning with an aspirator. The purpose of aspiration is to remove fluid or air from an affected area (as in pleural effusion, pneumothorax, ascites, or an abscess) or to obtain specimens (such as blood from a vein or serum from the spinal canal).

Equipment

Aspiration equipment includes disinfecting solution for the skin; local anesthetic; two aspirating needles; a vacuum bottle or other closed system for receiving the fluid; a sterile receptacle for the specimen; sterile sponges, towels, and basins; sterile gloves, face masks, and gowns; and surgical dressings as the case may require.

Patient care

The nurse assists with the aspiration procedures by assembling necessary equipment, by explaining the procedure and expected sensations to the patient, and by ascertaining that a consent form has been signed. The patient is draped to ensure privacy and warmth as well as emotional comfort. Emotional support is provided throughout the procedure. The operator is assisted in obtaining and processing specimens. The type and amount of any drainage or aspirated material is observed and documented. The operative site is dressed, and patient outcomes and any complications are monitored.

The respiratory therapist is primarily responsible for aspirating excessive airway secretions. This procedure may be done as a therapeutic maneuver to ease breathing or as a diagnostic procedure to collect a sputum sample for analysis of the microbes associated with the infection.

suction aspiration

Vacuum aspiration.

suprapubic aspiration of urine

A procedure for draining the bladder when it is not possible to use a urethral catheter. The skin over the lower abdominal area is cleansed. An incision in the abdominal wall is made with a needle or trocar to gain access to the bladder. To prevent complications during the procedure, it is important to observe the following guidelines: The patient should be positioned in the marked Trendelenburg position. The bladder should be distended with 400 ml of fluid. Any previous abdominal wall incisions that may have left the bladder or bowel adherent to the scar tissue should be noted. The incision should be no more than 3 cm above the pubic symphysis. The trocar should be inserted 30° toward the bladder, i.e., away from the pubic symphysis (if in doubt, a small-gauge needle should be inserted for orientation); the trocar should not be placed in a vertical direction. The depth of trocar insertion should be monitored, using gentle pressure on the trocar to prevent damage to the bladder base.

CAUTION!

The needle may pierce a loop of bowel that is lying over the anterior surface of the bladder.

testicular sperm aspiration

Abbreviation: TESA
The procurement of sperm directly from the testes, e.g., by surgery or needle aspiration. Similar techniques include microsurgical aspiration of sperm by micro-epididymal sperm aspiration (MESA) or percutaneous epididymal sperm aspiration (PESA).

transbronchial needle aspiration

Abbreviation: TBNA
A method of sampling abnormal tissue masses found in the mediastinum. A needle is guided into the mass during bronchoscopy, and cells are dislodged with a sawing motion. Suction is applied to gather specimens. TBNA is typically used to determine whether the mass represents a malignancy, such as a bronchogenic carcinoma or lymphoma.

vacuum aspiration

Evacuation of the contents of the uterus by a curet or catheter attached to a suction apparatus. The procedure is performed before the 12th week of gestation. It is the most common form of surgical abortion. Synonym: suction aspiration
