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.
Background and aims: Acute respiratory distress syndrome (ARDS) treatment is supportive, and there is no currently approved treatment for it. This study, therefore, aimed to investigate the effect of endotracheal administration of N-acetyl cysteine (NAC) and heparin on the level of secretion and partial thromboplastin time (PTT) in ARDS patients under mechanical ventilation. Methods: In this clinical trial study, 70 patients aged over 18 years (30 women and 40 men) admitted to the intensive care unit were randomly selected following the allocation rule and then divided into two groups (intervention and control). In addition to the routine and available treatments in the ward given to the patients in both groups, the control group also received 10 mL of normal saline every six hours through the endotracheal route, while the intervention group received 500 units of heparin plus 200 mg of NAC dissolved in 10 mL of normal saline every six hours through the same administration route. Results: The mean and standard deviation levels of PTT in the control and intervention groups were 30.3743 ± 7.78008 and 32.2286 ± 8.31047, respectively, with no significant difference (P>0.05); the volume of secretion on days 1-3 was not significantly different between the two groups, but the difference was statistically significant from day 4 onwards (P<0.05). Conclusion: Taking the combination of NAC and heparin through the endotracheal route was effective in reducing pulmonary secretion, and may have been considered a considerable positive step in providing patients suffering from acute respiratory failure and under mechanical ventilation with supportive care. However, it is recommended that further clinical studies be conducted before arriving at any definitive conclusion.
