تاثیر موسیقی بر علائم حیاتی و درصد اشباع اکسی هموگلوبین بیماران بعد از عمل جراحی قلب باز: کارآزمایی بالینی تصادفی شده

Background and purpose: The monitoring of the patients&rsquo; hemodynamic status and vital signs is a routine practice in &Iuml;&Ccedil;&Uuml; and the use of a low-cost and soothing method to maintain stable physiological parameters is necessary. This study aimed at investigating the effect of music on the vital signs and Sp&Ocirc;2 of patients after open heart surgery. Materials and methods: This study was a randomized clinical trial (R&Ccedil;T) conducted on 60 patients hospitalized in the open heart surgery &Iuml;&Ccedil;&Uuml; of Mazandaran Heart &Ccedil;enter. Patients were randomly assigned into case and control groups. &Iuml;n the case group, the patients listened to the music, which they selected before, through headphones for 30 minutes, while headphones without playing any music were used for patients in the control group. Vital signs and Sp&Ocirc;2 of the patients were assessed before the intervention, immediately, 30 and 60 minutes after the intervention. The data were analyzed using &Ccedil;hi-square T-test and repeated measure statistical tests. Results: Findings showed that music led to a significant decrease in the rate of heartbeat, systolic blood pressure, and mean arterial pressure and a significant increase in Sp&Ocirc;2 rate (P<0.05) was also observed. But music had no significant effect on the respiratory rate and diastolic blood pressure (P>0.05). &Ccedil;onclusion: &Acirc;s a non-pharmacologic, inexpensive, non-invasive method and without any side effects, music can improve the vital signs of the patients after open heart surgery.
