Fluctuation of blood pressure and pulse rate during colostomy irrigation
1Department of Surgery, Tokai University School of Medicine, Japan.
Purpose:
The aim of this study was to determine the effects of colostomy irrigation on the vital signs of patients with left colostomy.
Methods:
Twenty-two consecutive patients who underwent abdominoperineal resection for cancer of the lower rectum and had left lower quadrant end colostomy were included in this study. Subjective symptoms, blood pressure, and pulse rate during the first irrigation were investigated.
Results:
Fluctuation of blood pressure during instillation was 8.0/8.5 mmHg (average) and 25.0/17.9 mmHg during evacuation. Fluctuation of pulse rate was 5.5 per minute (average) during instillation and 11.5 per minute during evacuation. The number of subjects who showed more than 20% fluctuation of systolic pressure was 12 (54.5 percent) and that of diastolic pressure was 14 (63.6 percent). One of 22 patients complained of illness during irrigation.
Conclusion:
Although colostomy irrigation showed no significant effects on vital signs in the majority of patients, it caused a significant reduction in both blood pressure and pulse rate in a small number of patients. Careful attention should be paid to vital signs considering the possibility of such effects, especially on the initial irrigation.
