The Role of Ketamine as an Adjuvant Therapy for Children With Acute Status Asthmaticus

Augusta University

Overview

The purpose of this investigation is to perform a pilot study assessing the safety and utility of intravenous ketamine as an adjuvant therapy in the emergency department setting for pediatric patients in acute status asthmaticus who have failed standard emergency therapy.

This is a pilot study of a cohort of 20 subjects to assess the feasibility, safety and efficacy of ketamine in status asthmaticus. The study will take place at the Augusta University's pediatric emergency department 24 hours a day. The attending physician who is clinically treating the patient will identify the patient as a potential study candidate (see inclusion criteria). Study team members will then be notified and obtain informed consent for potential participants who meet the inclusion/exclusion criteria. Once a patient in the Augusta University Children's Hospital of Georgia Pediatric Emergency Department is deemed a potential study subject, informed consent will be obtained by the research study team members. The patient and their parents will be provided with all the required information about the study including potential risks and benefits associated with participation. The information will be presented in a private setting in a language the patient understands. The patient and/or their parent/guardian will have opportunities to ask questions and will be given enough time to consider participation before providing consent. A document will be given to obtain assent/consent that reiterates all the information about the study (including reason for the study, risks, benefits, etc.) Study team members that will be actively involved in the study will be either pediatric emergency medicine faculty or pediatric emergency medicine fellows that are on staff. Patients that meet the inclusion and exclusion criteria will have ketamine 1 mg/kg IV bolus administered once informed consent has been obtained.

Outcomes

Primary Outcomes

Efficacy of ketamine in status asthmaticus by assessing change in clinical asthma score (CAS)

CAS will be documented on admission, prior to intervention, 30 minutes and 60 minutes after administration of ketamine. The CAS is a scoring system to assess the severity of asthma used by Augusta University and is based on physiological measurements and clinical appearance.

Time frame: prior to intervention, 30 minutes and 60 minutes after administration of ketamine
