Effectiveness of Positioning on Back Pain After TACE Among Patients With HCC

Study Overview
=================
Brief Summary
-----------------
Changing patients' position in the bed after TACE can decrease the level of back pain without increasing the amount of bleeding and hematoma,bring patients some comfort and relieving abdominal bloating, increase patients' satisfaction.

Detailed Description
-----------------
Background：During the treatment for the liver cancer patients who are treated by Transcatheter Arterial Chemoembolization (TACE), the embolic agent with chemotherapeutic drugs are injected through a catheter into a femoral artery directly supplying the tumor. Hence, after the procedure, to avoid bleeding and hematoma at the puncture site, the puncture site at groin needs to be pressed by sandbag and the affected limb needs to remain straight. These patients have to lay down on beds and are not allowed to move for at least 4 hours. Due to pressure exerted continuously to the same muscles, may cause back muscle rigidity and spasms, these patients may suffer from back pain and discomfort. In addition to usual pharmacological treatment, nursing intervention aimed at decreasing patient discomfort, therefore, this study will refer to the previous researches to develop the methods and procedures of changing body positions and apply these methods to the liver cancer patients who are treated by TACE. Purpose：The aim of this study was to compare the level of back pain and on the amount of bleeding and hematoma between those patients changing body positions in bed and those patients not changing body positions after TACE. Methods: This study was a randomized clinical trial. The sample consisted of 78 patients who had undergone TACE via the femoral artery, patients by using a convenience sampling assigned to either the control or experimental group (each group consisting 39 participants). All patients need to be pressed on the puncture site at groin with a sand bag of 2.5 kg for 2 hours and lie down for 4 hours. The control group received the usual care, remaining supine position in complete bed rest and immobilized. Experimental group patients received position changes in the second hour and the fourth hour after TACE. Results: The overall trend of back pain is different between the two groups ( p <.001) , the mean of pain intensity in the second ( p =.006) and the forth hour ( p <.001) showed a significant difference. Experimental group patients had significantly less back pain than the control group after TACE . For the within subjects factor of time, the levels of back pain differed significantly across the five-time periods in experimental group ( p < .05) . In the aspect of post embolization syndrome , control group patients had significantly abdominal bloating than the experimental group ( p =.003) . None of patients developed hematoma, there was no significant difference between the two groups in terms of amount of bleeding. On the whole, experimental group patients had significantly higher satisfaction than the control group ( p =.018).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The overall trend of back pain | The patients were asked to describe their back pain and rate its severity by using the Numerical Rating Scale (NRS-11).To determine if there is any significant difference the two groups. The NRS-11 with scores of 0 and 10 indicating no pain and excruciating pain, respectively. | Within 4 hours after TACE | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The mean of back pain between two groups | The patients were asked to describe their back pain and rate its severity by using the Numerical Rating Scale (NRS).To determine if there is any significant difference the two groups. | Within 4 hours after TACE | 
| The mean of back pain in the experimental group | To determine if there is any significant difference across the five-time periods in experimental group. | Within 4 hours after TACE | 
| The mean of back pain in the control group | To determine if there is any significant difference across the five-time periods in control group. | Within 4 hours after TACE | 
| Vascular complication | The hematoma in femoral access site or there is blood on the yarn roll were visually checked, its margin was marked by a marker and its size was measured by using measuring paper. (The area equal to a square that is 1 millimeter on each side). | Femoral puncture sites were assessed every hourly for the following 4 hours by researcher and a nurse. | 
| Post embolization syndrome | This is a dichotomized variable. Various common symptoms were listed and checked off based on the patient's report. | Within 4 hours after TACE. | 
| Patients' satisfaction | 5-Point Likert Scale: with scores of 5, 4, 3, 2, and 1 indicating highly satisfied, satisfied, neutral, dissatisfied, and highly dissatisfied, respectively. Higher scores mean higher satisfaction. | Patient's satisfaction will be evaluated at the 4th hour. |
