مقایسه تهوع و استفراغ ضمن همودیالیز در دو وضعیت خوابیده به پشت و نیمه نشسته

Background and purpose: The most common treatment used for end-stage renal disease (ESRD) is hemodialysis. Although, this treatment caused may promote longevity, however, many complications may occur, such as nausea & vomiting. Body position during hemodialysis has an effect on nausea & vomiting episodes, patients who may lay in Semi fowler position during hemodialysis are able to communicate with circumstances comfortably, furthermore, with inner organ self arrangement into body in a semi-fowler position, the stomach discharges quickly. In this study, we assessed nausea & vomiting during hemodialysis, in two supine and semi fowler position. Materials and methods: In this quasi-experimental study, one group (pre -post test),45 patients under hemodialysis in Zabol City, were placed in two positions and in each position, which took two sessions, controlled indexes for nausea and vomiting within each half hour and if changes occurred, in that moment controlled appeared. Results: Nausea incidence, during hemodialysis did not have a significant difference within the two positions. Vilkaksons test showed significant difference (P<0/05) in frequency, duration and severity of nausea incidences in two positions, while these indexes in semi- fowler position were reduced. With Vilkaksion and Mac Nemar test, any significant difference between frequency, duration and severity of vomiting incidences did not exist. Conclusion: Regarding the finding that showed majority of nausea & vomiting indexes occurrences was similar in both positions, the other index was reduced in semi- fowler position. Furthermore, since this position has been more comfortable for patients, we would suggest using semi- fowler position with hemodialysis.
