<qa>  What is the name of the procedure that will be randomized to be performed by?Infants hospitalized in the NICU undergo numerous invasive and painful procedures. Exposure to early repeated painful procedures has been correlated with both short-term and long-term negative sequelae, such as altered pain responses and increased sensitivity to pain Taddio 2005. Fifty eligible infants in the NICU will be randomized to undergo urine collection by either suprapubic aspiration SPA or urinary catheterization UC. Outcome measures will include pain, procedure success, and procedure duration. Pain will be measured using facial grimacing the infants face will be videotaped for the entire procedure, heart rate and oxygen saturation. Procedure success will be defined by the collection of about 2mL of urine Falcao, 1999. The procedure duration in seconds for the first attempt will be calculated. Infants will be monitored during the procedure for adverse events such as apnea, bradycardia, desaturation, emesis, increased ventilatory support. Results will be extremely valuable in aiding health care providers to choose a urine collection technique that minimizes the pain and maximizes the success of the procedure.
