Description
A STUDY OF SAFE BATHING FOR MYOCARDIAL INFARCTION PATIENTS BY ANALYZING PARAMETERS RELATED TO HEART BEAT
   
  Sumiko Higo: Associate Professor: Okayama prefectural University.
 Kiyoko Fukai: Professor: Graduate School of Health Sciences, Okayama University
â… ï¼ŽPurpose:We aimed to investigate safe bathing for myocardial infarction patients(MIPs)by analyzing heart beats on electrocardiograms (ECG) recorded while the subjects were bathing.
Ⅱ.Design : Nonrandomized controlled trial.
Ⅲ.Population/sample studied : Patient group (PG) consisted of 19 acute MIPs (mean age, 61.1±9.2 yrs), and control group (CG), 19 healthy adults (61.0±5.7 yrs).
Ⅳ.Methods:During 15 minutes bradykinetic bathing, subjects soaked two times in the hot bathtub at 40 degrees C for 3 min. They scrubbed their bodies with soap outside the bath-tab for 2 and a half minutes.Blood pressure and holter ECG were recorded continuously.
Ⅴ.Data/analysis:The data were analyzed using Mann-Whitney and Wilcoxon's rank sum tests. The level of significance was adopted under 5%.
Ⅵ.Findings:No subjects complained of any symptoms. Neither serious arrhythmia nor ST-T changes on ECG were observed in any subject. However, premature ventricular contraction (PVC), classified into grade 2 of Lown Classification, was observed on ECG in the three PG subjects, who had left ventricular ejection faction (LVEF) of 40-49%. The PVC occurred more frequently by bathing. There were no significant differences between the activities of sympathetic and parasympathetic nerves, nor between R-R intervals of the 2 groups. But systolic blood pressure was lower in PG than in CG by bathing (p<0.05).
Ⅶ.Implications:The patient, whose LVEF is less than 40-49% and have frequent PVC, is supposed to have risk for PVC during bathing.
Ⅷ.Conclusions:Although 15 minutes hot bathing with slow movement is safe procedure for MIPs, it has a risk of frequent PVC.
Ⅸ.Length for period of study:1/5/2008 ~ 31/3/2010
Ⅹ.Funding received:Grant-in-Aid for Scientific Research (C) by Japan Society for the Promotion of Science(JSPS)
