Abstract
Summary
Prehabilitation enables patients to withstand the stress of surgery by augmenting functional capacity; improves physical and psychological readiness for surgery, reduces postoperative complications and the length of stay, and improves the transition from the hospital to the community. Acardiac prehabilitation program should include education, nutritional optimization, exercise training, social support, and anxiety reduction, although current existing evidence is limited. (Pokhrel et al., 2021)
Quasi experimental (study and control) research design was utilized; this study was carried out in cardiothoracic surgery department at Assiut university heart hospital. The study was including sample of 60 adult patients (male and female), (30patients studies, and 30patients control) at cardiothoracic surgery department at Assiut university heart hospital. Patient age ranges from 18 to 65 years; Patient undergoing coronary artery bypasses graft.
The study assessed by tool (1), then assessed by tool (2)
Tools of the study:
Two tools was utilized in this study
Tool (1): Patient’s assessment sheet: It was developed by the researcher based on current national and international literatures it includes three parts:
Part 1: Demographic patient data: this part was including Patient’s name, age, gender, marital status, level of education and occupation.
Part 2: Patient’s medical data: This part aimed to assess of the following, Risk factors include (hypertension, diabetes, smoking, impaired renal function, impaired liver function, idiopathic pulmonary fibrosis (IPf), obstructive pulmonary disease (CoPD), and obesity.
Part 3: - General health assessment sheet (Rancic et al., 2020): compared between two group postoperatively (Blood pressure, Heart rate, Saturation, I cu length of stay, Length of hospital staying, Physical function, Pain, Physical performance and Validity).
Tool (2): Assessment of physical activity and functional capacity for patient: includes two parts:
Part 1: - Six Minute walking test (Du et al., 2009): Evaluated the submaximal effort, the capacity to perform the daily living activities, as well as the objective assessment of symptoms and functional capacity for exercise, Place cones at either end of the 30 meter stretch as turning points. It has been used to measure the level of functional capacity for exercise: Nothing at all dyspnea-Very, very slight dyspnea, Slight dyspnea-Moderate dyspnea -Somewhat severe dyspnea -Severe dyspnea.
Part 2: The Borg Rating of Perceived Exertion (RPE) scale (Pageaux, 2016), measured the level of physical strain or perceived exertion. The Borg 15-point RPE scale a rating of 6 was to be associated with no exertion, i.e. rest, and a rating of 20 with maximal exertion, i.e. the most stressful exercise performed.
The main findings of this study were:
1-According to Socio-demographic data of patients more than one third of the study patients and control (43.3%. 46.7%) their age ranged from 50 less than 60 yrs. The majority of both groups (76.7%, 83.3%) were male. The vast majority of both groups (96.7%, 83.3%) were married. Half of both groups (50.0%) were read and write. More than one third of both groups (43.3%, 46.7%) were office work
2-Regarding the majority of the study patients were smoking (70.0%) and half of control patients were smoking (60.0%). And one third of the study patients and control (30.0 %. 33.3%) their age are Cigarette smoking. And there were no statistical significance difference between study and control groups as regarding Smoking number per\day. And there were statistical significance difference between study and control groups as regarding Number of cigarette. And there were no statistical significance difference between study and control groups as regarding Hypertension, Diabetes, Impaired liver function, Impaired renal function, and Obstructive pulmonary disease (CoPD)
3-Regarding body mass index the more than two third of the study patients were overweight (73.39%) and half of control patients were overweight (50%). And there were no statistical significance difference between study and control groups.
4- Regarding comparison between study and control group regarding Hemodynamic values that there were statistical significance difference between study and control groups as regarding Hemodynamic values in Diastole blood, saturation, ICU stay and Length of hospital stay. There was no statistical significance difference between study and control groups.
5- As regarding comparison between study and control group regarding General health there were statistical significance difference between study and control groups as regarding general health in Physical function, pain, Physical performance and Validity
6- There was highly statistical significance difference between study and control groups as regarding 6minuts walk test (p. value=.004).
7- That there was statistical significance difference between study and control groups as regarding Borg rating of perceived exertion scale. (p. value=.000).
8- Relation between demographic data and physical activity among study and control group there were no significance relation between demographic data and physical activity patient’s age, gender, education level, occupation, marital status for study group, And there were no significance relation between demographic data and physical activity patient’s age, education level .but there were significance relation between demographic data and physical activity patient’s gender, occupation, marital status for control group
9- Relation between demographic data and function capacity among study and control group there were no significance relation between demographic data and function capacity patient’s age, gender, education level, occupation, marital status for study group, and there were no significance relation between demographic data and physical activity patient’s age, education level .but there were significance relation between demographic data and function capacity patient’s occupation
10- There were positive statistical significance correlation between study group and medical data regarding physical activity and function of body mass index.
11- There were positive statistical significance correlation between study group and medical data regarding physical activity and function of heart rate, saturation, ICU stay.
12-there were positive statistical significance correlation between study group and medical data regarding physical activity and function of pain, physical performance, Validity
