CRITICAL APPRAISAL 2
Introduction
The current assignment provides the critical appraisal of the quantitative study ‘'
Childhood preoperative anxiolysis: Are sedation and distraction better than either alone? A
prospective randomized study''. This critical appraisal aims to investigate the cost and
effectiveness of Midazolam in reducing the anxiety and pain among children before and after
an operation. The study has been correlated with recent data to assess its reliability and
effectiveness. The results of the study have been elaborated with the implication of
medication in clinical practice both professionally and scientifically.
Q: Is this quantitative research report a case study, case-control study, cohort study,
randomized control trial or systematic review?
Ans: The quantitative study was a randomized prospective study that primarily focuses
on evidence-based practice in relieving pain among children.
Q: Where does the study fall in the hierarchy of evidence in terms of reliability and risk
of bias?
Ans: The research found to be reliable, as the large body of researches supported the
findings of the study. In contrast, a few contradictory studies provide different results.
Concerning the substantial body of researches, the current study found to be valid and
reliable. Klein, (1992) and Fazi, Kurth, Jantzen, Watcha & Rose, (2001) provided a similar
result to control the pre and post-operation pain.
Q: Why was the study done? (Define the problem and purpose.)
Ans: Pain and anxiety in a hospital or clinical setting are widespread. The children
experience substantial pain and severe anxiety before and after an operation. The pain and
anxiety are vital to reduce for getting positive post-operation results. The children should not

get anxious in pre or post-operational state. The recent data suggested that numerous
researchers, pediatrics and doctors are working to find out the ways to reduce the pain and
anxiety among patients. The current study aimed at investigating the effectiveness of
Midazolam in the preoperative stage in controlling the postoperative pain. The results of the
study would provide evidence to control the situation in hospital settings.
Q: Where the steps of the study identified?
Ans: The current study comprised of three stages, which was mentioned in the study. In
the first stage, the pre-assessment was taken from the children. Two standardized scale visual
analog anxiety scale, Yale preoperative anxiety scale, post-operative pain scales were used to
collect the data. In the second stage, childhood midazolam, with digital viseo player,
preoperative anaxiolysis were implemented.. Lastly, the post-assessment was taken. The
significant difference in pre and post assessment was found.
Q: What was the sample size?
Ans: One thirty-five children aged 2-12 years were selected in the controlled randomized
program. The children were distributed into three sets to assess the efficiency of midazolam.
In the intervention delivery, three preventative strategies were used to investigate the results.
Q: Are the measurements of major variables reliable and valid? Explain.
Ans: The assessment of the construct was reliable as the standardized tools were used to
collect data. Such as modified visual analog anxiety scale, Yale preoperative anxiety scale,
post-operative pain, disorientation satisfaction, and the satisfaction of parentswere also
assessed.
Q: How were the data analyzed?
