Research Abstract

(1) After a 15-minute footbath one subject showed a 134 ml increase of urinary output.
The effects of footbath on the improvement of postoperative dysuria have been verified and the following findings obtained.
1. Foot bath were conducted for 20 minutes on 11 healthy adults using the latest, sealed type of footbath with the following results.
(1) Urinary output and increment increased significantly 40 minutes after the footbath. Five subjects presented noticeable urinary output of 319 to 580 ml during the 90-minute examination, and there was a positive correlation between the rate of change of fingertip temperature and the increment size of urinary output.
(2) With regard to the autonomic nervous system, there was a positive correlation between' the rate of change of HF (parasympathetic nervous system) and the increment size of urine output in the 6 subjects whose urine output increased gradually.
The above findings indicate that the footbath improves precapillary circulation, enhances rela xation, and increases urine output.
2. Thirty-two people who had undergone general anesthesia during an operation and experienced insertion of an indwelling urinary catheter were interviewed in order to understand their behavioral processes and recognition of such processes before the first urine discharge.
(1) Their behavioral processes have been classified into 6 patterns: "Comparing present status with past experience"; "Trying to avoid past disgusting experience" ; "Making good use of past experience"; "Fearing that something negative they had seen or heard might happen to themselves"; "Checking with the medical professional about the present experience point by point"; "In their inexperience, leaving all to the medical professional".
(2) The recognition of such behavioral processes was based upon: "whether or not the patient has experienced the insertion of indwelling urinary catheter," and "whether the patient is affirmative, negative, or uncertain depending on what they had seen or heard, or neither affirmative nor negative."
(3) Problems of difficult urination experienced before the first urinary discharge covered: When to urinate, where to urinate, suitable clothing, appropriate posture, fluctuation of call of nature, delay of urinary discharge, lessening of urinary flow, and insufficient feeling of relief.
3. Footbath used on 3 patients with dysuria after operations resulted in the following:
(2) The parasympathetic nervous system was activated both by sensing comfort through bathing their feet in hot water and by moving their feet freely.
Foot bath care made the subjects feel that they were recovering, serving as a turning point for them to take the initiative in improving their situation.
