in ketamine vs in midazolam and fentanyl for abscess i&d

Conditions: Abscess; Pain

Summary: the general objective of this study is to determine whether intranasal ketamine should be incorporated into formulary as an option to treat pain during minor procedures in the pediatric emergency department.

in the pediatric emergency department, one of the main goals in patient care is to provide adequate pain management. many patients present to the emergency department with conditions or injuries that cause acute or chronic pain. health care providers routinely aim to treat patients' pain in a timely manner after arrival to the emergency department. a common scenario occurs when a patient presents with a condition in which treatment will require that a potentially painful or anxiety-provoking procedure will be performed in the ed, and providers also strive to treat this pain and anxiety accordingly. there are several different methods for treating pain and anxiety, including multiple types of medications, which can be given orally, intravenously, intramuscularly, or intranasally. the use of intranasal medications for the treatment of pain and anxiety has been steadily increasing over the last decade, and this has been particularly helpful in the pediatric population. there are several advantages of using intranasal medications, including rapid onset, ease of administration, and lack of need for iv access. at this time, this pediatric emergency department uses two different medications via the intranasal route of administration: fentanyl, a synthetic opiate, and midazolam, a benzodiazepine, which are used for pain control and anxiolysis, respectively, and these two medications are frequently used together. the objective of this study is to introduce ketamine as a third medication for intranasal use and to observe its effects on pain control; this medication is currently used either intravenously or intramuscularly in the investigator's ed. ketamine is an anesthetic that has properties of analgesia and amnesia and has a generally favorable side effect profile. this study will observe the effects of using a medication that is already widely used in the investigator's ed, but it will be used via a different route of administration, offering advantages over other options. in this study, patients will be enrolled who have been diagnosed with a soft tissue abscess that will be treated with incision and drainage in the ed. patients in one group will be given a dose of intranasal ketamine at a predetermined dose, and measured variables will include pain score, vital signs, patient and/or parent satisfaction, adverse effects, length of stay, and need for additional doses of ketamine or additional medications. this group of patients will be compared with another group of patients who will be given intranasal fentanyl and intranasal midazolam using a randomization through the redcap system. the investigators hypothesize that the use of intranasal ketamine in this ped for treating pain associated with the minor procedure of incision and drainage of a soft tissue abscess will provide satisfactory pain control in these patients while offering advantages over other treatment options, as compared with patients treated with the current standard intranasal medications.
