Accuracy of Eye Evaluation of Amount of Urine in Urine Drainage Bag Checked with Super Save Equipment by Anesthesiologists and Nurse Anesthetists at Chaoprayayommarat Hospital

Abstract

Introduction: This research was a cross-section analytic study about an evaluation of amount of urine in patients undergoing surgery to decrease the complications and mortality rate due to inappropriate fluid management

Objective: The primary objective is to evaluate the accuracy of amount of urine in urine drainage bag with the eyes checked with Super save equipment. The secondary objective is to study the price of Super save equipment.

Materials and Methods: Population was the anesthesiologists and nurse anesthetists. Sample was the anesthesiologists and nurse anesthetists in Chaoprayayommarat Hospital (n= 24). The research tools were Super save equipment and a urine drainage bag filled with a tap water mixed with safflower tea. The data were recorded in the case record form which was divided into 2 parts; the first part was a baseline characteristic and a demographic data, the second part was the accuracy of the evaluation of amount of urine. The samples evaluated 20 levels (5 to 500 milliliters (ml.)) of tap water mixed with safflower tea contained in the urine drainage bag which routinely used in the operating room. The researcher recorded the water levels according to the samples evaluated and checked with Super Save equipment, which consisted of easily available items in the anesthesia department. (three-way stopcock, suction tube, extension tube, 10 ml of syringe and 1000 ml of recycle distilled water bottle. Data collection was done during April 1 to June 30, 2018. The data was analyzed with a descriptive statistic and reported with number and percentage.

Results: The result showed the average amount of water level evaluated with eyes was lower than which checked with super save equipment. The accuracy of evaluation with eyes which was greater than or equal 90% of the actual water level was very low (0-37.5%) in 20 water levels. At the level 40,70,90,100,130,150 and 470 ml, there were 0% of accuracy. In low water volumn of 5, 10 and 15 ml, the most accurate estimated value were 37.5, 37.5 and 25% of the sample, respectively. The price of Super save equipment was 27.05 baht

Conclusion : The accuracy of water level evaluation from the urine bag with the eyes of anesthesiologists and nurse anesthetists is very low. Super save equipment is the useful and affordable device to improve the accuracy of urine evaluation and further improve proper fluid management to the patients.
