Relation between preoperative autonomic function and blood pressure change after tourniquet deflation during total knee replacement arthroplasty / 대한마취과학회지

BACKGROUND: Tourniquets are used to provide a bloodless surgical field for extremities. Hypotension due to vasodilation and bleeding after tourniquet deflation is a common event. Hemodynamic stability is modulated by the autonomic nervous system (ANS). Heart rate variability (HRV) is a sensitive method for detecting individuals who may be at risk of hemodynamic instability during general anesthesia. The purpose of this study was to investigate ANS function to predict hypotension after tourniquet deflation. METHODS: Eighty-six patients who underwent total knee replacement arthroplasty (TKRA) were studied. HRV, systolic blood pressure variability (SBPV) and baroreflex sensitivity (BRS) were analyzed. We assigned two groups depending on the lowest systolic blood pressure (SBP) or mean BP (MBP) after tourniquet release (Group H; SBP 80 mmHg and MBP > 60 mmHg). RESULTS: Fifteen patients developed severe hypotension and ten patients were treated with ephedrine. Of the parameters of HRV, SBPV, and BRS, only BRSSEQ was significant being low in Group H. BRS and high-frequency SBPV were correlated with the degree of MBP change after tourniquet deflation. CONCLUSIONS: Preoperative low BRS is associated with hypotension after tourniquet deflation, suggesting the importance of baroreflex regulation for intraoperative hemodynamic stability.

A Study on the Urinary Incontinence, Lower Urinary Tract Symptoms, Lifestyle and Sexual Matters of Women in an Urban Area / 성인간호학회지

PURPOSE: The purpose of this study was to identify the frequency of urinary incontinence and lower urinary symptoms, to identify lifestyle and sexual matters for UI of adult women in an urban area. METHOD: The sample consisted of 364 educated women from a women's health education program in a public health center. For data collection, the Bristol Female Lower Urinary Tract Symptoms Questionnaire developed by Jackson, et. al.(1996) and the demographic questionnaire were used. For data analysis, SAS 8.2 program was used. RESULT: The results were as follows: 1. the prevalence rate of UI was 73.63%. 45.88% of them were stress incontinence and 27.75% of them were urge incontinence. 2. Remarkable differences were found between the type of UI and LUTS in the case of urgency(x2=42.0585, P<0.001), unexplained incontinence(x2=59.0585, P<0.001), noctural incontinence(x2=18.8080, P<0.001) and catetherization(x2=10.7207, P= 0.004), burning sense(x2=27.7400, P<0.001). 3. Remarkable differences were found between the type of UI and lifestyle matters in the cases as follows fluid intake restriction(x2=31.0532, P=0.008), interference in physical activity(x2= 36.7481, P=0.001), interference in relation with others(x2=22.2729, P=0.034). 4. Remarkable differences were found between the type of UI and sexual matters with difficulty of sexual intercourse(x2=16.1898, P=0.002), and urine leakage during sexual intercourse(x2=17.9752, P=0.001). CONCLUSION: Based on the results, developing and carrying out an adequate UI care and education program is needed.
