Clinical Trial Summary
The goals of this randomized controlled trial are:
1. To determine the mean gastric residual volume in ICU admitted adult patients before and
after intervention.
2. To compare the gastric residual volume between the intervention and control group.
Participants will be randomized in two groups (intervention and control group)
Intervention group:
The intervention period will be 3 days for intervention group. These patients will receive 20
minutes of abdominal massage twice a day, and the interval between two massages will be 2
hours. The outcome variable variable gastric residual volume will be measured every day,
before the intervention and 1 hour after the second massage. the GRV will be measured in ml
(via feeding syringe) and marked on checklist.
Control group The control group will receive standard/usual care The abdominal massage
technique will consist of five steps based on tensegrity principle
Description:
Food intolerance is one of the major problems of intensive care unit (ICU) admitted patients,
receiving enteral nutrition. An important nursing priority for these patients is the
prevention and management of food intolerance. This necessitates the use of techniques and
procedures for increasing the rate of gastric emptying, and so enhancing tolerance to this
nutritional support modality. Abdominal massage is a method that has shown to improve many
digestive functions such as constipation and gastric residual volume (GRV), but a small
number of studies have been conducted on NG fed patients in intensive care units, and
occasionally, contradictory findings have been found. Furthermore, more studies were
recommended to reach a definite conclusion on this intervention. The aim of this study is to
determine the effect of abdominal massage on the gastric residual volume in patients
hospitalized in intensive care units in a tertiary care hospital, Lahore. It is hypothesized
that ICU admitted patients who will receive abdominal massage will have a difference in
gastric residual volume than patients who will not.
Study Design A randomized controlled trial (RCT). Study setting The study will be conducted
at Intensive care units of Jinnah Hospital, Lahore. Study Population Patients having
nasogastric tube (NGT) for feeding and admitted in ICU with GCS below 7.
Sample size A sample size of 34 patients is calculated by using the formula of comparing
means between two group and by taking power of study 80%, confidence level 95% ,mean gastric
residual volume of intervention group 97.30 ml, mean gastric residual volume of control group
143.46 ml, standard deviation of gastric residual volume of intervention group 54.06 ml and
standard deviation of gastric residual volume of control group = 39.93 ml.
Sampling technique patients will first be selected by non-probability convenient sampling.
Then patients will be randomized into two groups by lottery method (17 patients in each
group).
Data will be collected by using a researcher-designed checklist which will consist of two
parts:
Demographic characteristics and medical data Gastric residual volume (GRV) monitoring The
intervention period will be 3 days for intervention group. These patients will receive 20
minutes of abdominal massage twice a day, and the interval between two massages will be 2
hours. Every day, before the intervention and 1 hour after the second massage, the GRV will
be measured I ml (via feeding syringe) and marked on checklist. The abdominal massage
technique will consist of five steps based on tensegrity principle.
Data will be analyzed by using statistical package for social sciences (SPSS) version 24.
Descriptive statistics (frequency, percentage, mean and standard deviation) will be used to
describe the characteristics of study population. Chi square test will be used to examine the
demographic information of the two groups based on qualitative variables. Independent t test
will be used to compare the mean of the total GRV in both groups before and after
intervention. The significance level of the tests will be considered at <0.05 Findings of
this study will provide base line data about the effectiveness of abdominal massage among
adult critically ill patients' gastric residual volume. This procedure can be considered as a
care method to improve nutrition status in patients hospitalized in these units. This
inexpensive and complementary nursing therapy will be suggested to add in standard ICU
nursing care practices for decreasing gastric residual volume and fulfilling required calorie
intake, decreasing risk of complications and hospital stay and improving healing.
