Abstract: In order to evaluate the effect of standardized management on spinal cord injury patients with neurogenic bowel dysfunction, 50 cases of spinal cord injury patients from January 2011 to December 2013 were treated with neurogenic bowel intestinal standardized management. The effect was compared to that with routine nursing of 32 spinal cord injury patients from January 2009 to December 2010. Data analysis regarding the age, spinal cord injury, neurological movement and basic sensory score showed no statistically significant difference between the two groups (P > 0.05). However, bowel functional indexes including abdominal distension, abdominal pain, evacuation time and anal incontinence of the standardized training group decreased as compared to those of control group (P < 0.05). The bowel way of the standardized training patients was also in line with normal living habits, including fixed time and the toilet bowel movement. In conclusion, standardization bowel management intervention is beneficial to the patients with spinal cord injury to form regular bowel habit.

Neurogenic bowel dysfunction (NBD) caused by spinal cord injury (SCI) would lead to intestinal sensorimotor disorders. The consequences include altered bowel motility, loss of sphincter control and an inability significantly to increase intra-abdominal pressure [1,2]. Bowel care is a time-consuming work, leading to an increase in the level of anxiety and depression [3-5]. An effective bowel program should cover the issues of constipation, effective evacuation and prevention of complications [1,6,8]. The objective of the current study was to evaluate the improved bowel management applied to 50 individuals with SCI in hospital from Year 2011 to 2013, when comparing with 32 individuals by normal care from Year 2009 to 2010.
2. Materials and Methods
2.1. Subject Selection
Fifty patients with SCI from Jan, 2011 to Dec, 2013 in the First Affiliated Hospital of Jinan University were selected as treatment group, containing 36 men and 14 women with average age 30±10.2. Injury type: 20 cases of complete injury; 30 cases of non-complete injury; 44 cases with thoracic lumbosacral injury; 6 cases of cervical injury. Inclusion criteria: after spinal shock, no original intestinal disease; patient or his/her caregiver willing to cooperate. Thirty-two SCI patients with bowel dysfunction during Jan, 2009 to Dec, 2010 with routine nursing were selected into control group by a retrospective analysis.
2.2. Standardized Bowel Training
Fifty individuals in treatment group underwent standardized bowel management. Intestinal stool was cleared by enema or oral laxatives 3 days before the training. The standardized bowel training process was as follows. Step 1, develop a diet plan to make sure an amount of intake of water and cellulose. Step 2, guide the patients to massage the lower abdomen clockwise for 20 min, from ascending colon, transverse colon and descending colon to sigmoid; with light to heavy pressure, then to light pressure. Guide the patients’ external anal sphincter to close and levator ani muscle to increase the nerve sensitivity. Step 3, stimulate the skin around the anus, with an interval of 2 min. Step 4, simple evacuation: 40 mL glycerine enema insertion into rectal ampulla or deeper parts. Step 5, tell patients not to evacuate with heavy pressure first; 10 min after the management, massage then try evacuate; or manual evacuation.
Standardized bowel training was taken every day or every other day with a fixed time, based on the psychological need, bowel habit before injury and injury severity. The amount of water intake in Step 1 was combined with bladder training. Step 2 was taken every day. Step 3 was decided by the tightness of the anus, if it did not work then performed Steps 4 and 5. A table was developed to record the bowel situation; the training was last for 2 weeks to observe the best bowel method for each patient, then other methods were taught.
Patients in control group were nursed by routine care, including cleaning care to independent evacuation patients; laxatives given and dietary guidance when constipation happened; skin care and antidiarrheal treatment when diarrhea happened.
2.3. Observing Index
The evaluation of bowel recovery of neurogenic bowel dysfunction has been started since last century and bowel dysfunction and the associated psychological abnormalities were evaluated by intestinal function and survival quantity . In China, the measurement method of intestinal function is always taken by determination of colonic transit time  and anorectal manometry [11,12]. But during the actual nursing practice, these indexes are hard to achieve. So we took some effective and measurable observation indexes including 1) with/without bloating or abdominal pain; 2) independent evacuation, fixed evacuation every day or every other day by rectal irritation or laxatives, with soft defecate; 3) no bowel incontinence between evacuations; 4) the times of evacuation less than 30 min.
2.4. Statistical Analysis
Age, sense and movement or other indexes between the treated group and control group were analyzed by SPSS 19.0. The statistical significance of the differences was analyzed using Student’s t-test between two groups. P < 0.05 was considered to be statistically significant.
According to the American Spinal Injury Association (ASIA) , age, moter, sensory scores were evaluated between the standardized group and control group. Statistical data were presented as mean±SD. P > 0.05 was considered as significant difference. The results shown in Table 1 indicated that the SCI severity between the standardized group and control group had no significant differences.
|Group||Cases (N)||Age||Moter score||Sensory score|
|Light Touch||Pin Prick|
Evaluation of intestinal function was performed as mentioned in the method section. The percentage scores were shown in Table 2. These data showed that the standardized bowel training significantly reduced the bloating or abdominal pain, increased independent evacuation by patients themselves, reduced bowel incontinence and shortened the time of evacuation.
|Standardized group (N=50)||Control group (N=32)||Z index||P value|
|Bloating or abdominal pain [n(%)]||0(0%)||19(59%)||-6.178||0.00|
|Fixed independent evacuation [n(%)]||50(100%)||10(31%)||-7.024||0.00|
|Evacuation less than 30 min [n(%)]||40(80%)||8(25%)||-4.901||0.00|
The current study revealed that after bowel management, intestinal functions including bloating, abdominal pain, fixed independent evacuation, incontinence and evacuation time of the patients with SCI were largely relieved or shortened, as compared to control group with regular nursing care. The evacuation way (referred to fixed evacuation time in toilet) was close to normal life, indicating the successful achievement of standardized bowel training of SCI patients.
Neurogenic bowel dysfunction (NBD) can be divided into reflexic and areflexic types. Because the undamaged spinal cord (S2-S4), fulfilled stool can stimulate the evacuation of patients with reflexic NBD, but the process is not controlled by brain, leading to incontinence and incomplete evacuation; in patients with areflexic NBD, these stimulation wouldn’t cause evacuation. Therefore, during the early period of bowel training, we often apply enema or laxatives to empty the intestines, thus reducing constipation and incontinence.
The opportunity is large for incomplete paraplegia patients with functional external anal sphincter to recover spontaneous evacuation. Patients with SCI, especially those with unaffected arms and hands could be reemployed and get back to work. Factors that affect the reemployment are multiple. SCI results in the loss of normal motor and sensory function, leading to severe disability and reduced quality of life . A research showed that 1/3 of SCI patients thought that after SCI stabilized, the impact of intestinal dysfunction was more severe than that of bladder or sex dysfunction, and 41% thought that bowel dysfunction was a moderate or severe problem that affects lifespan . Bowel dysfunction would lead to a series of problems such as restricted outdoor activity, mental stress and other psychological pressure. Obviously, the early intervention with standardized bowel training would largely contribute to the forming of ordered and regular evacuation of SCI patients, further reducing their mental stress, increasing the reemployment desire and finally benefiting the life quality of these SCI patients.
Neurogenic bowel dysfunction is important for the quantified life in persons with spinal cord injury, especially in physical functioning and physical component summary. Standardization bowel management intervention benefits the patients with spinal cord injury to form regular bowel habit, thus improving the life living quantity.
