Effects of Position Change After PCI

Study Overview
=================
Brief Summary
-----------------
Aims and objectives: To determine the effect of position change that is applied after percutaneous coronary intervention on vital signs, back pain, and vascular complications. Background: In order to minimize the post-procedure complications, patients are restricted to prolonged bed rest that is always accompanied by back pain and and hemodynamic instability. Design: Randomized-controlled quasi experimental study Methods: The study sample chosen for this study included 200 patients who visited a hospital in Turkey between July 2014 and November 2014. Patients were divided into two groups by randomization. Patients in the control group (CG, n = 100) were put in a supine position, in which the head of the bed (HOB) was elevated to 15°, the patient's leg on the side of the intervention was kept straight and immobile; positional change was applied to patients in the experimental group (EG, n = 100).

Detailed Description
-----------------
Percutaneous coronary intervention (PCI) is an interventional procedure used to diagnose and treat chronic coronary artery disease. The recommended period of bed rest following a PCI is reported by Rolley et al. (2011) as being 2-4 hours (h). According to evidence-based guidelines in relevant literature, however, the bed rest was reported from 2-24 h; in these instances the supine position (SP) was used, which leads to movement limitation. Among the patient-care goals during the post-procedural period, sustaining tissue perfusion and heart and vascular system operation, regulating vital signs, reducing pain, and supporting movement are important. According to such a procedure, the nurse's independent role is to provide the safest position for the patient, thereby positively affecting vital signs after PCI and reducing vascular complications and back pain. Recently, similar nursing studies have reported the effect of position change after PCI on back pain, as well as vascular complications after PCI, the effect of position change on certain vital signs and vascular complications, the effect of position change regarding pain, patient comfort and certain vital signs, and the effect of positional change on intervention pain and all vital signs. Some studies have also looked into the effect of positional changes on back pain, certain vital signs, and vascular complication. Prolonged bed rest in a SP has become tradition, but it can have negative effects. Comprehensive studies in the existing literature that can be applied to the post-PCI nursing care process-and which study the effect of the most reliable positional change on all vital signs, vascular complications, and, back pain-display a numerical inadequacy. Consequently, the authors intend the current study to be an experimental investigation of the effect of position change on vital signs, vascular complications, and back pain.

Interventional Model Description: Randomized-controlled quasi experimental study
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control group (CG)<br>Patients in the CG were provided with routine nursing care, as practiced in the clinic, including restricted bed rest. For this purpose, patients were given supine position in which the HOB was elevated 15° for 6-10 h; the patient's leg on the of the side of intervention was kept straight. | |
| Experimental: Experimental group (EG)<br>Patients in the EG were applied position changes between the first minute and sixth hour. During the initial six hours a supportive, thin pillow, 4 x 40 x 100 cm in size, was placed between the patient's shoulders and gluteals; this reduced the pressure on local tissues and muscle groups. | Other: position change applied at different times<br>* Time 1 - in the first fifth minute after the procedure supine position in which the HOB was elevated 15° Time 2 - in the first hour low fowler's position were given in which the HOB was elevated 15-30° Time 3 - in the third hour semi high fowler's position were given in which the HOB was elevated 30-45° Time 4 - in the fourth hour left or right lateral position were given in which the HOB was elevated 15° Time 5 - in the fifth hour low fowler's position were given in which the HOB was elevated 15-30° Time 6 - in the sixth hour standard fowler's position were given in which the HOB was elevated 45-60°<br>|
