RESUMEN
OBJECTIVES: Injuries induced by the brain trauma from mild to life-threatening therefore prevents these complications need psychological, environmental, and physical support. Acupressure by reduces muscle tension, improves blood circulation and stimulates endorphins secretion naturally reduce pain in these patients therefore the aim of this study was to evaluate effect of acupressure on the level of the blood pressure, respiratory rate, and heart rate in patients with the brain contusion under mechanical ventilation. METHODS: The present study was a clinical trial with a sample size of 64 brain contusion patients who were selected based on available sampling and then randomly assigned to control and experimental groups. Demographic information and check list of blood pressure, heart rate, and respiratory rate were recorded before intervention in two groups then acupressure at the p6 point for 10 min in both hands at the morning and evening for two consecutive days is done in intervention group while in control group this pressure was applied at the same time point at an inactive point such as thumb hands. After acupressure for both groups, physiological index was measured immediately, half and 1 h after every acupressure. Data were collected using a demographic questionnaire and physiological sheet. Data was analyzed using SPSS 21 software and analytical statistical tests (independent t-test, chi-square, Fisher's exact test). RESULTS: The mean of blood pressure, heart rate, and respiratory rate before acupressure there was no significant statistical difference between two groups (p>0.05). but the mean of two consecutive days of blood pressure, heart rate, and respiratory rate after acupressure in the intervention group than control group was significantly different (p<0/05). Therefore, physiologic index before acupressure than after acupressure in the intervention group was significant statistical difference (p<0.001). The mean difference before the intervention than 12 h after the last intervention between two group was significant statistical difference (p<0/05) which that detected the stability of the effect of acupressure. CONCLUSIONS: The results indicate that p6 point acupressure in the brain contusion patients under mechanical ventilation has been associated with improved blood pressure, pulse rate, and respiratory rate. While confirmation of these results requires further studies, but use of complementary medicine in recovery the physical condition and strengthening of the effect of nursing care of these patients should be considered.
