Abstract
Abstract Aim.The purpose of this study was to examine the effect of white noise on the anxiety of patients in the Cardiac Care Unit (CCU). Background. Many patients with cardiovascular disease suffer from some degree of anxiety after admission to CCU. Anxiety adversely affects patients' recovery. Method.This was a quasi-experimental study conducted in ShaheedRajaei Cardiovascular Center, Tehran in 2014. Ninety patients admittedto the cardiac care unit were recruited in the study based on convenience sampling and divided into experimental and control group (45 patients in each group). Anxiety was measured in both groups for 2 consecutive days by DASS-21 questionnaire. In the experimental group, white noise with an intensity of 50 to 60 decibels was played for 30 minutes. Data were analyzed by SPSS , version 17, using independent t-test, paired t-test and chi-square test. Findings. In control group, the difference between mean scores of anxiety, before and after intervention was not statistically significant (5.17±3.90 and 4.73±3.77, respectively p=0.08). In the experimental group, the difference between mean scores of anxiety, before and after intervention was statistically significant (5.38±3.87 and 4.58±3.71, respectively p=0.01). Conclusion.The white noise can reduce the anxiety of patients admitted to CCU. This method can be used as a simple and low-cost non-pharmacological intervention for these patients.

Abstract
Aim. This study aimed to evaluate the effect of preoperative cardiac surgery nursing care education on anx-iety, quality of sleep, fasting time and cardiac medication usage in cardiac surgery patients.
Background. Cardiac surgery is one of the most important therapeutic approaches in patients with heart diseases. According to previous studies it is necessary to reduce the anxiety level and improve the quality of sleep the night before surgery, fasting according to standard protocols and continuing usage of cardiac medications.
Method. This study was a quasi-experimental trial in which patients were studied in two groups (before-training group and after-training group). One hundred cardiac surgery patients were selected based on in-clusion criteria as before-training group and evaluated in terms of anxiety level, quality of sleep, fasting time and cardiac medication usage in the night before surgery. Sampling lasted for 42 days. Then, all of the surgical nurses were trained individually for a week, and given pamphlets. Their educational content in-cluded the latest fasting protocols, non-pharmacological methods of reducing anxiety and improving quality of sleep and emphasizing on the importance of cardiac medication usage in the night before surgery. Then, another 100 patients were evaluated as the after-training group. Sampling from this group lasted for 38 days. The tools included demographic sheet and Spielberger anxiety questionnaire. Data were analyzed with SPSS software.
Findings. The findings of this study showed a statistically significant difference in anxiety level between before-training group and after-training group (P<0.0001). Also, there was a significant statistical differ-ence in quality of sleep between two groups (P=0.004). But, there was not a statistically significant differ-ence in fasting hours and cardiac medication usage between two groups.
Conclusion. According to the findings, educating preoperative cardiac surgery nursing care decreased anxi-ety level and improved quality of sleep in after-training group. But this intervention neither decreased fast-ing hours nor increased continuing cardiac medication usage in after-training group.

Abstract
Aim. This study examined the effect of white noise on depression of patients in the Cardiac Care Unit (CCU).
Background. Many patients with cardiovascular disease are susceptible to experience depression after admission in Cardiac Care Unit (CCU). Depression can influence patients' recovery.
Method. This was a quasi-experimental study conducted in Shaheed Rajaei Cardiovascular Center, Tehran in 2014. Ninety patients admitted to the cardiac care unit were recruited in the study based on convenience sampling and divided into experimental and control group (45 patients in each group). Depression was measured for 3 consecutive days by depression subscale of DASS-21 questionnaire. In the experimental group, white noise with an intensity of 50 to 60 decibels was played for 30 minutes. Data were analyzed by SPSS , version 17, using independent t-test, paired t-test and chi-square test.
Findings. In control group, no statically significant difference was observed between mean scores of depression, before and after intervention (4.12±4.35 and 3.52±3.74, respectively; p=0.05). In the experimental group, the difference between mean scores of depression, before and after intervention was statistically significant (4.81±4.47 and 3.93±4.48, respectively; p=0.02).
Conclusion. According to the findings, white noise can leads to a significant reduction in depression. This intervention can be used as a simple and low-cost non-pharmacological care for these patients.

Abstract
Aim. The aim of this study was to evaluate the effect of using “Pain Assessment Tool” by nurses on analgesics requirement and patient’s satisfaction after coronary bypass graft surgery.
Background. One of the main duties of caregivers in ICU is relieving patients’ pain. Using "Pain Assessment Tool" may have a positive effect on the choice of analgesics and dosage adjustment with patients’ requirements. More research is still needed.
Method. In a clinical trial, 153 hospitalized patients in the intensive care unit were selected randomly and were divided into two experimental (n=77) and Control group (n=76). The Pain Assessment Tool and pain management for 48 hours were implemented for conscious patients. Routine measures were taken into account for control group and the severity of pain and analgesic injection for experimental group were determined. In both groups, the amount of analgesics administered for pain relief, and patient satisfaction were recorded. Data were analyzed by SPSS version 16.
Findings. The use of Pain Assessment Tool increased the number of recipients of analgesic drugs and reduced their dosage over 48 hours in the experimental group. Also, the satisfaction of pain relief was higher in the experimental group than the control group (p<0.0001).
Conclusion. The findings of this study demonstrate the positive effect of Pain Assessment Tool on pain control, proper use of analgesics, prescribing the proper dose of analgesics based on patients’ pain and satisfaction improvement. The measurement of pain severity using Pain Assessment Tool, before and after analgesics administration is suggested.

Abstract
Aim. The aim of this study was to evaluate the effect of early mobility on respiratory parameters in patients after open heart surgery.
Background. Post-operative phase of open heart surgery is the most critical period during which many serious and fatal complication can occur. Early mobility can prevent such complications. The role of the critical care nurse is crucial in this regard.
Method. In a randomized clinical trial, 104 patients who were candidate for open heart surgery were randomly assigned to experimental (n=52) and control (n=52) group. Patients in control group received hospital routine treatments. Patients in experimental group were mobilized from the bed in the first, second and third day after surgery. Early mobility included change position, siting on the bed, legs dangling off the bed, sitting in the chair next to the bed, and walking). The effect of early mobilization on respiratory indices was examined. Data were analyzed in SPSS version 18 using independent t-test, Chi-square and one way ANOVA statistical testes.
Findings. There was no statistically significant difference between groups regarding demographic variables and underlying disease. Better lung function and arterial blood gases suitable changes were seen in the experimental group. Inspiratory capacity and arterial oxygen saturation was greater in the experimental than control group.
Conclusion. Early mobility after open heart surgery is a safe and effective intervention and can have a positive effect on the patient's respiratory indices reducing pulmonary complications following surgery.

Abstract
Abstract
Aim. The purpose of this study was to compare the effect of clinically-indicated replacement and routine replacement of peripheral venous catheters on catheter-related complications and satisfaction in patients undergoing cardiac surgery.
Background. The insertion of peripheral vein catheter is one of the most commonly used minimally invasive measures in hospitalized patients. Catheters can be maintained until they are working well.
Methods. A randomized controlled clinical trial was conducted in intensive care units of Rajaie Cardiovascular Medical and Research Center in 2017. After ethical Approval, 104 Patients were randomly allocated to either clinically-indicated replacement or routine replacement of peripheral venous catheters (every 96 hours) (52 Patients in each group). Data collection tools included demographic form, catheter placement data sheet and a researcher-made patients’ satisfaction questionnaire. Data were analyzed in SPSS using descriptive and inferential statistics.
Findings. There were no statistically significant difference in terms of the incidence of complications between the groups. Also, there were no statistically significant difference between the scores of satisfaction of the patients of the control and experimental group.
Conclusion. No evidence was found of superiority of routine replacement of peripheral venous catheters over clinically-indicated replacement. Caregivers may consider changing the protocol of catheter replacement from routine replacement to clinically-indicated replacement. This would protects patients from the unnecessary pain of routine replacement in the absence of clinical indications.

Abstract
ABSTRACT
Aim. The aim of the present study was to examine the effect of early mobilization protocol on the strength of diaphragmatic muscle and other inspiratory muscles after open heart surgery.
Background. Early mobilization is recommended as a safe protocol after open heart surgery to decrease hospital stay and post-op respiratory complications; however, our knowledge about its effect on improving respiratory muscles strength is limited.
Methods. This is a randomized single-blinded clinical trial conducted on 80 consecutive patients who underwent coronary artery bypass surgery and/or valvular surgery that were randomly assigned to experimental group (postoperative early mobilization) and control group (routine physiotherapy). On the day before surgery and the day before leaving intensive care unit (ICU), two scores were measured for assessing diaphragmatic muscle strength: maximum inspiratory pressure (PI max) and Strength index (S index). Hemodynamic parameters were also measured and compared.
Findings. According to both PI max and S index, diaphragmatic muscle strength decreased from 77.28 to 59.53 cmH2O in patients after surgery, but the changes in the experimental group was less than the control group, which indicates a significant improvement in the strength of the diaphragm muscle in the experimental group (p≤0.0001). Hemodynamic changes after surgery (lower blood pressure and increased heart rate) occurred in both groups without any significant clinical effect.
Conclusion. Early mobilization after cardiac surgery has positive effect on the strength of diaphragmatic muscle and is also safe as shown to have no adverse effect on hemodynamic parameters.

Abstract
Aim. This study aimed to compare the effect of Adaptive Support Ventilation (ASV) and Synchronized Intermittent Mandatory Ventilation-Pressure Support (SIMV-PS) modes on consequence of weaning off patients from mechanical ventilator after coronary artery bypass surgery
Background. The ventilation mode used for respiratory support in patients after coronary artery bypass graft surgery is very important. In addition to avoiding pressure on patient's sternotomy incision, the ventilation mode should also provide the possibility of rapid weaning of patient to avoid complications caused by long-term ventilation.
Method. In a semi-experimental study, 26 patients were ventilated with ASV as the experimental group and 26 patients were ventilated with SIMV-PS mode as the control group after coronary artery bypass graft surgery in Rajaie Cardiovascular Medical and Research Center, Tehran, Iran. Mechanical ventilation time and endotracheal tube removal time, hemodynamic variables, and arterial blood gas analysis were compared between the two groups. Data were analyzed using an independent t-test, repeated measures ANOVA and chi-square.
Findings. Out of 52 patients, 36 (69.2 percent) were male and 16 (30.8 percent) were female. The mean time for the endotracheal tube removal was 89.42±33.83 minutes in the experimental group and 101.53±44.91 minutes in control group, which did not have a statistically significant difference (p=0.843). The mean duration of mechanical ventilation of patients in the experimental group was 483.84±158.153 minutes and in the control group, it was 541.92±257.81 minutes, which were not statistically different (p=0.332).
Conclusion. The use of ASV mode for mechanical ventilation after coronary artery bypass graft did not affect reducing the duration of mechanical ventilation and the time of endotracheal tube removal compared to SIMV-PS mode. Therefore, the use of ASV mode for respiratory support of patients undergoing coronary artery bypass surgery should be considered according to the patient's condition and the nurses' expertise.
