Post-operative pain

Candidate patient for inguinal hernia surgery will be selected through convenience sampling and with Block random allocation method will be applied to the case and control groups. we use of block randomization To create two identical groups, first for each of group will be allocated letters A and B. size of blocks will be foursome, After the list of all possible modes and assign a number to each one, some block will be selected through Table of random numbers until number of sample to be 60

In this study patients will be informed that they will participate in study but they will not notice that they are in the case group or in the control group. Samplers will not notice that which group are the case group and which group are the control group ( materials required for intervention will be given to samplers in the form two containers with the names A and B and will not be given explanatory about content of the container for them), Also, nurses are working in the department will not be informed of the case or control groups.
