Filter by:The investigators proposed study will investigate the efficacy of tablet computer distraction as an analgesic for the pain associated with various painful procedures in the emergency department. Since prior studies have shown that distraction by a parent or nurse can be an effective analgesic, there is reason to believe that tablet computer distraction will similarly reduce pain. Participants in the control group will receive a cartoon on the TV monitor in the patient room, while participants in the study group will receive a more immersive distraction of playing a game or watching a cartoon (for children too young to play a game) on a tablet computer. Data from this study will help inform best practices for administering painful procedures in a way that minimizes pain.
Premature neonates admitted to the neonatal intensive care unit (NICU) require up to several hundred procedures during their hospitalization. Many of these are tissue-damaging procedures (TDPs) that cause pain. Through our NIH funded research, we made the novel observation that exposure to a single TDP can significantly increase ATP utilization and oxidative stress, as evidenced by increased plasma levels of hypoxanthine, uric acid and malondialdehyde in neonates exposed to TDPs as compared to controls (no TDP). Because neonates are exposed to numerous TDPs, it is relevant to explore the energy costs of repeated exposures to painful procedures, an important information that is currently not known, as the effect of this cumulative metabolic dysfunction could result in potentially treatable or preventable cell injury. Oral sucrose analgesia is frequently given to relieve procedural pain in neonates on the basis of its effect on behavioral and physiological pain scores. However, we found, through our prospective, randomized, double blind study funded by NIH, that although oral sucrose significantly reduced pain scores, its administration before a single TDP (heel lance) significantly increased ATP utilization. This is evidenced by higher plasma concentrations of hypoxanthine and uric acid in neonates given sucrose compared to control neonates (no TDP, no sucrose) or neonates just given a pacifier. These novel findings raise concern because preterm neonates have limited ATP stores and are susceptible to cell injury due to ATP depletion. In addition, it raises the relevant concern: If a single dose of oral sucrose can alter ATP metabolism, what are the effects of exposure to multiple doses of oral sucrose? More importantly, what is the effect of multiple TDPs and/or multiple oral sucrose dosages on ATP utilization, oxidative stress and cell injury? This application will also explore the effect of 30% oral glucose, another sweet solution currently used to relieve pain, on ATP metabolism. In this study, we will test the general hypothesis that exposure to multiple TDPs and/or multiple doses of oral sucrose analgesia compared to oral glucose or standard care, alter biochemical markers of ATP utilization, oxidative stress and cell injury. We will use a prospective randomized clinical research design to test this hypothesis during days of life 3-7 of human premature neonates. Increased ATP utilization will be quantified by concentrations of hypoxanthine, xanthine and uric acid measured using HPLC. Oxidative stress will be quantified by concentrations of allantoin using gas chromatography/mass spectroscopy, and cell injury will be quantified through urinary concentration of intestinal fatty acid binding protein, an early marker of enterocyte injury. Data from this application will provide insight into the cellular and biochemical effects of repetitive and accumulated TDPs and/or multiple doses of oral sucrose. With this knowledge, we will propose and test innovative strategies that will not only decrease pain but also will prevent cell injury or cell death.
Colonoscopy is generally considered an invasive procedure that causes remarkable pain to the patient. The pain associated with the procedure is not caused by the insertion of the scope but from inflating of the colon in order to do the inspection. It has been shown that colonoscopy can be performed successfully without sedation (Leung, 2010), but many patients feel discomfort during the procedure. Factors predicting a painful colonoscopy are female-gender, degree of patient nervousness and the technical difficulty of the colonoscopy (Ylinen et al. 2009). Also age under 40, previous abdominal surgery and use of sedation are associated with painful colonoscopy ( Seip et al. 2009). Most often sedation and/or analgesia are achieved by administering a benzodiazepine or a combination of a benzodiazepine and an opioid (Fanti et al. 2009, Maskelar et al. 2009,), dexmedetomidine (Dere et al. 2009) or by using non-pharmacologic methods (Amer-Cuenca et al. 2011). Tramadol as monotherapy did not significantly decrease pain intensity or endoscopist's evaluation of colonoscopy (Grossi et al. 2004). Currently, intravenous midazolam is the drug used most commonly to introduce some sedation for colonoscopy. Intravenous sedation definitely increases the cost of procedure; drug administration, need for pulse oximetry monitoring and the need for follow-up after the procedure make colonoscopy sometimes expensive and troublesome. It has also been shown, that low-dose midazolam neither relieves discomfort nor makes patients forget it (Elphick et al. 2009). Fentanyl is a short-acting opioid widely used in anesthesia management. Transmucosal sublingual formulation of fentanyl has been developed to further improve the management of pain. When administered as a sublingual fast-dissolving tablet (Abstral®) that is placed under the tongue, the effects is fast and predictable. Its active ingredient is absorbed by the body through the mucous membrane. After administration of buccal fentanyl maximum plasma drug concentration was measured after 25 minutes (Darwish et al. 2011). Plasma fentanyl concentrations versus time following buccal and sublingual administration are very similar (Darwish et al. 2008). Abstral® sublingual tablets should be administered directly under the tongue at the deepest part. Sublingual administration is an easy and non-invasive method of pain treatment for the patient coming to colonoscopy done as an office based procedure. Other advantages compared to invasive methods are improved comfort of patients and no need for intravenous access because of pain relief. Before, it has been used in the management of breakthrough pain in cancer patients. Sublingual fentanyl is shown to be effective and well-tolerated for the treatment of breakthrough cancer pain (Uberall et al. 2011). The use of transmucosal tablet for colonoscopy patients is a quite new approach.
