Early Detection of Respiratory Depression in Post-Operative Patients Self-Administering Analgesia
MetadataShow full item record
Problem Under Investigation: Rapid patient deterioration can occur anytime during the post- operative period without close patient monitoring. Opioid induced respiratory depression is the most common and fatal event that occurs with the use of patient-controlled analgesia (PCA). Placing the post-operative patient with a PCA pump on a continuous pulse oximetry (POX) monitor is a new protocol at a suburban hospital. The intended effectiveness of this policy has not been evaluated. Objective: To determine effectiveness of continuous pulse oximetry on patients using PCA (patient controlled analgesia) and the prevention of rapid responses. Background Literature: Prior studies have yielded contradictory results regarding the use of continuous pulse oximetry monitors on post-operative patients. There is a lack of literature on patient’s using PCA pumps. Theoretical Framework: The Conceptual Model for Nursing Health Policy. This policy focuses on a new policy evaluation. Project Methods: Comparative descriptive design and retrospective chart review with a sample size of 120 patients. No continuous pulse oximetry monitor (n=60) and placement of continuous pulse oximetry monitor (n=60) were compared. Data analysis completed using t-test and chi-squared test. Data Analysis: T-test was used to analyze and compare the rapid responses between groups and was not statistically significant. t-test and chi-square test was used to compare the variables between groups to see if any were confounding. Results: Consequently, differences in the two groups could not be determined by this study due to a p-value greater than .05. Conclusion: Although there was no statistical significance, there was clinical significance with a decrease of rapid responses from 5 to 1 between the two groups. Ultimately, further research with a larger sample size is needed on continuous pulse oximetry monitors placed on patients using PCA analgesia.
