Introduction: Bed sore is an important complication of operation. Long immobility, hypotension and hypothermia in perioperative period predispose patients to bed sore. The prevention of bed sore is a priority in caring for immobilized patients and different methods have been used for this purpose. Hydrocolloid dressing is one of these methods.

Materials and Methods: This study is a quasi-experimental research. Subjects consisted of 60 patients aged 40-70 years who had eligibility criteria for this study. Subjects were selected with convenience sampling and randomly allocated to two 30-patient groups (experimental and control). In experimental group, hydrocolloid dressing was used before surgery. No procedure was performed for control group. After surgery sacral area was examined on three occasions to detect bed sore: immediately, 24 and 48 hours after surgery. The data were collected by demographic questionnaire and staging bed sore checklist and analyzed by SPSS statistic program and use of descriptive methods such as Chi square, Fisher exact test, t test, ANOVA and least significant difference (LSD).

Results: Incidence of bed sore was 13.3% in experimental group and %36.7 in control group. Chi square test showed significant difference between incidence of bed sore in two groups (p=0.03). Incidence of bed sore in two groups had no relationship with respect to gender and number of grafts. There was a significant relationship between bed sore and age, body mass index and duration of hypothermia, immobility and cardiopulmonary bypass (p<0.05).

Conclusion: Considering findings of this research, it seems that use of hydrocolloid dressing is effective in preventing perioperative bed sore after coronary artery bypass surgery.

Background & Aim: Decreasing mechanical ventilation and early extubation after cardiac surgery are the important scientific subjects that their clinical and financial benefits had been demonstrated. There are some variables that are associated with extubation time so, determination of them will help nurses to plan appropriate care aimed at doing an early and safe extubation.

Methods & Materials: The purpose of this descriptive-analytic study was to determine whether any preoperative variable had a significant effect on extubation time after CABG. The research was conducted in one of hospitals in Tehran city. In this retrospective study, data were collected by reviewing of files of eligible patients who were undergoing CABG from December 2003 to March 2005. 93 files reviewed by convenience sampling method. Collecting data tool was a checklist consists of three parts: 1) demographic characteristics 2) health and disease history 3) physiologic status. Samples divided into two groups: early and delayed extubation (>6h). Data analysis was performed by descriptive methods, chi square, fisher exact test and regression analysis.

Results: Mean and standard deviation of duration time of intubation was 7.19±3.00 with range of 3-18.25 hours in all samples. Totally 43% of subjects extubated in ≤6h and 57% of them in >6h. Age was the only preoperative variable that was found to be statistically significant to extubation time (p=0.01).

Conclusion: According to our findings age is associated with postoperative intubation time after CABG. It means older patients need to be under long mechanical ventilation. So, nurses should make a decision on extubation in older patients, carefully.

Background & Aim: Sedation after coronary artery bypass graft surgery can prevent the side effects of the treatment. The purpose of this study was to determine the effect of controlled sedation based on the Richmond scale on the duration of mechanical ventilation and the changes of blood pressure in patients following coronary artery bypass graft surgery.
Methods & Materials: In a single blind randomized clinical trial (IRCT2017050517693N2) from June to August 2017, a convenience sample of 80 patients after coronary artery bypass graft surgery, hospitalized in the intensive care unit of Heshamat Center, Rasht, were selected and randomly allocated into two groups (each group=40). Sedative drug dose was determined using the Richmond agitation sedation scale in the intervention group and determined routinely (based on hemodynamic changes) in the control group. Pain as a confounding variable was evaluated using CPOT tool. Data were analyzed by descriptive statistics and Chi-square, Mann-Whitney, independent t-test and repeated measures ANOVA using the SPSS software version 22.
Results: The mean age of samples was 59.89±7.53 and 66.7% of them were male. There was a significant difference between two groups in the duration of mechanical ventilation (P<0.04), the changes of patients’ blood pressure (P<0.05), need for a vasopressor drug (P<0.05) until extubation and need for the first administration of sedatives (P<0.001).
Conclusion: Utilizing the Richmond tool can reduce the patient’s dependence on ventilator and changes in arterial pressure. Also, using this tool can prevent unnecessary and early administration of sedative and vasopressor drugs in patients.

Background & Aim: Nowadays, home-based cardiac rehabilitation (HBCR) program is one of the major methods that can improve the quality of life of patients following coronary artery bypass graft surgery. The present study aimed to investigate the effect of a HBCR on the quality of life of patients following CABG.
Methods & Materials: In this clinical trial, 104 inpatients at Golestan and Imam Khomeini hospitals in Ahvaz in 2017, based on permuted-block randomization were assigned to an intervention or a control group. The intervention group received four training sessions for four days at the hospital and then six sessions of home-based cardiac rehabilitation (at 2-week intervals for three months). The Mac-New quality of life questionnaire was completed by the intervention and control groups before the surgery and three months after CABG surgery. Data were analyzed using the SPSS software version 22.
Results: The postoperative mean scores for quality of life subscales and for overall quality of life in the intervention group were greater compared to the control group (P<0.001). The obtained effect sizes were 1.17 for the emotional, 1.42 for the physical, and 1.91 for the social subscales and 1.67 for the overall quality of life. The Eta-squared value (0.408) indicated that the effect of the home-based cardiac rehabilitation program on the quality of life was significant (P<0.0001).
Conclusion: The study findings suggest that the home-based cardiac rehabilitation program has positive effects on the various subscales of quality of life. HBCR is recommended as a cost-effective care model for all patients attending heart surgery centers.

Background & Aim: The availability of information regarding people's experiences of returning to work after heart surgery, taking into account the socio-cultural context of Iranian society, is limited. The aim of this study is to discover the process of returning to work after heart surgery.
Methods & Materials: A qualitative study using the grounded theory approach was conducted between 2021 and 2022. Through purposive and theoretical sampling, 21 participants who had undergone heart surgery and were in the process of returning to work were selected. They were chosen from the cardiac surgery ward of Amiralmomenin Hospital in Kordkuy, as well as among patients seeking treatment from cardiac surgeons in Golestan province. Data were collected through conducting semi-structured interviews and taking field notes. Data analysis was conducted using the method proposed by Corbin and Strauss in 2015.
Results: "Feeling of doubt about return-to-work", "perceived psycho-social support", "personal and occupational factors", "unfavorable consequences of heart surgery" and "limited support from governmental/non-governmental institutions" were determined as contextual factors influencing the process of return-to-work. Moreover, "effort to adjust the job", "situation evaluation" and "self-management" were introduced as strategies, while "adaptability to the job" were identified as the consequence of returning to work. Finally, the core variable of the study was determined to be "the thoughtful effort to match the job".
Conclusion: Based on the results, it was determined that several individual and environmental factors influence the process of return-to-work for people who have undergone heart surgery. To facilitate a successful return to work, it is crucial to provide psycho-social support from both the family and work environment. It is recommended that policy makers in the health and social affairs sectors take active steps to empower people during the post-recovery period. Additionally, fostering collaboration between the Ministries of Labor and Health, as well as insurance organizations, can greatly facilitate the return to work of individuals after heart surgery.

Background & Aim: Anxiety is a significant psychological concern for patients undergoing coronary artery bypass graft (CABG) surgery. Orlando's nursing theory offers a framework for nursing interventions to mitigate this anxiety. This study aimed to evaluate the effect of a nursing intervention based on Orlando's theory on the level of situational anxiety in patients undergoing CABG.
Methods & Materials: This clinical trial was conducted in 2023 at Fatemeh-Zahra Hospital in Sari. A convenience sample of 70 patients scheduled for CABG was recruited and randomly assigned to either an intervention group (n=35) or a control group (n=35). The intervention group received nursing care based on Orlando's theory the evening before surgery, in addition to standard care. The control group received only standard care. Situational anxiety was measured using the Spielberger State-Trait Anxiety Inventory (STAI) (assessing situational anxiety) before the intervention and again on the morning of the surgery. Data were analyzed using Fisher's exact test, Chi-square test, independent t-tests, and paired t-tests in SPSS version 21.
Results: Before the intervention, there was no statistically significant difference in mean situational anxiety scores between the intervention and control groups (t=1.31, P=0.196). However, following the intervention, a statistically significant difference was observed between the two groups (49.29±5.29 vs 59.08±6.52; P<0.001). Specifically, the intervention group demonstrated a significant reduction in situational anxiety compared to the control group.
Conclusion: The results suggest that a nursing intervention based on Orlando's theory can effectively reduce situational anxiety in patients undergoing CABG. Therefore, it is suggested that nursing managers consider implementing educational programs based on this model to address situational anxiety in CABG patients.
