Observational Peripheral IV Insertion Study

As a preliminary study, the investigators are interested in conducting a prospective observational study to collect baseline data to characterize and collect baseline data on pain associated with needle catheterization in the hospital. Many factors including size of needle, experience of the individual placing IV, previous history of depression may vary the IV placement experience of a patient; however, only some of these factors may directly affect the magnitude of pain experienced by a patient. Currently, there is limited literature available on what factors affect the pain/satisfaction patients experience with IV insertion. Soysal et al. have previously reported that depressed patients reported higher severity of pain during IV catheter placement than non-depressed patients in a cross-sectional, observational study (n= 925). The authors have also demonstrated that age, sex, site of IV catheter insertion, use of antidepressant drugs, and whether the individual placing the IV catheter is a nurse or physician do not affect the magnitude of pain. Similarly, Van Loon et al have demonstrated that insertion of a smaller sized peripheral intravenous catheter did not result in lower pain sensation. However, Galvin et al. conducted a randomized clinical trial that demonstrated that the site of IV catheter insertion makes a difference in the pain patients feel during IV catheter insertion. Furthermore, no study exists that has investigated whether patients experience a different magnitude of pain when different levels of physician trainees place the IV catheter. Also, no study exists that compares whether peripheral IV cannulation with no pain relief method versus intradermal lidocaine 1% injection versus intradermal lidocaine 2% injection versus Buzzy® device affect the pain/satisfaction that patients experience with IV catheter insertion. Through the conduction of this study, the investigators hope to further evaluate which factors and techniques affect the experience patients have with peripheral IV cannulation; this knowledge could help the investigators figure out ways to make IV cannulation as comfortable as possible for patients in the future.
