- Lead Sponsor
- Jason Sperry
- Brief Summary
The Prehospital Analgesia INtervention trial (PAIN) is a proposed 4 year (3-year enrollment) multicenter, prehospital, randomized, double-blind, clinical trial that will enroll approximately 994 patients at select LITES Network sites. The objective is to perform a prospective, interventional, randomized trial among prehospital trauma patients with compensated shock (SI≥0.9) and an indication for pain management, comparing patient centered outcomes following prehospital administration of ketamine hydrochloride versus fentanyl citrate.

Group Intervention Description Ketamine Hydrochloride Ketamine Hydrochloride 2 blinded doses 2.5mg/ml ketamine hydrochloride in separately sealed pre-filled syringes Subjects will be administered the first dose over approximately 2 minutes via slow IV push. Pain assessment following administration will be obtained and recorded every 15 minutes. Redosing may occur after approximately 15 minutes if the subject has a qualifying pain score, there are no contraindications to pain medication per local protocol, and no exclusion criteria have been met. Fentanyl Citrate Fentanyl Citrate 2 blinded doses 10mcg/ml in separately sealed pre-filled syringes Subjects will be administered the first dose over approximately 2 minutes via slow IV push. Pain assessment following administration will be obtained and recorded every 15 minutes. Redosing may occur after approximately 15 minutes if the subject has a qualifying pain score, there are no contraindications to pain medication per local protocol, and no exclusion criteria have been met.
- Primary Outcome Measures
Name Time Method 24-hour mortality trauma bay arrival through 24 hours All cause mortality within 24 hours from time of trauma bay arrival
- Secondary Outcome Measures
Name Time Method Hypotension from initial administration of PAIN study prehospital analgesia through hospital arrival incidence of hypotension in the prehospital environment
Need for airway management from initial administration of PAIN study prehospital analgesia through hospital arrival need for airway management in the prehospital environment
Number of analgesic doses necessary to reduce pain level to <5 NRS or CPOT less than 2 from initial administration of PAIN study prehospital analgesia through hospital arrival Number of analgesic doses necessary to reduce pain level to \<5 on Numeric Rating Scale or less than 2 on Critical Care Pain Observation Tool. For Numeric Rating Scale, the patient rates their pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain. The Critical Care Pain Observation Tool is used for patients who are intubated and cannot verbalize a pain score. A nurse will observe behavior and score the patient's pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain.
Prehospital pain assessment following analgesia from initial administration of PAIN study prehospital analgesia through hospital arrival prehospital pain assessment using Numeric Rating Scale (NRS)/Critical Care Pain Observational Tool (CPOT) scores. For Numeric Rating Scale, the patient rates their pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain. The Critical Care Pain Observation Tool is used for patients who are intubated and cannot verbalize a pain score. Medical staff will observe the patient's behavior and score the patient's pain on a scale of 0 to 10, where 0 is no pain and 10 is the worst pain.
Hypoxia from initial administration of PAIN prehospital analgesia through hospital arrival incidence of hypoxia in the prehospital environment
Hospital length of stay from time of hospital admission to discharge number of days recorded to the first decimal from hospital admission to discharge up to 30 days
Trauma bay arrival pain score score assessed at time of arrival to trauma bay pain assessment using Numeric Rating Scale (NRS)/Critical Care Pain Observation Tool (CPOT) score. For Numeric Rating Scale, patients rate their pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain. The Critical Care Pain Observation Tool is used for patients who are intubated and cannot verbalize a pain score. A nurse will observe behavior and score the patient's pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain.
Survival to hospital discharge administration of PAIN study prehospital analgesia through hospital discharge or death up to 30 days survival to hospital discharge
Ventilator free days from administration of PAIN study prehospital analgesia through hospital discharge or death up to 30 days ventilator free days. Ventilator days are defined as number of days recorded to the first decimal spent on a mechanical ventilator subtracted from 30
Long term opioid use 3 months (+/- 1 month) and 6 months (+/- 1 month) following trauma admission long term opioid use assessed at 3 and 6 months. Patients who consent to further participation will be contacted to determine if they continued to use opioids (yes/no) at 3 and 6 months following trauma admission
24 hour opioid use from initial administration of PAIN study prehospital analgesia through 24 hours total 24 hour opioid use
Incidence of prehospital adverse events from initial administration of PAIN study prehospital analgesia through hospital arrival Incidence of adverse events of allergic reaction, emergence, laryngospasm, dysphoria, pruritus, and nausea
Baseline Pain/Anxiety/PTSD screening 0 hours to 2 weeks from time of hospital admission A subset of patients who consent to further participation will be assessed for Anxiety/PTSD using the Four-Item Patient Health Questionnaire (PHQ-4) for anxiety and depression, a two item pain severity scale (0=no pain to 10=worst pain), and the Injured Trauma Survivor Screen (ITSS)
Intensive Care Unit free days from administration of PAIN study prehospital analgesia through hospital discharge or death up to 30 days number of days recorded to the first decimal spent admitted to the Intensive Care Unit subtracted rom 30
Long term (6 month) outcome 6 months +/- 1 month following trauma admission A subset of patients who consent to further participation will be assessed for anxiety/depression/PTSD symptoms using the following tools: Generalized Anxiety Disorder (GAD-7), 8 item Patient Health Questionnaire (PHQ-8), and 8 item PTSD checklist (PCL-5)
Long Term Pain Assessment At 3 and 6 months (+/- 1 month) after hospital arrival A subset of patients who consent to further participation will be assessed for long term pain using a modified Brief Pain Inventory (numerical scale rating 0-10)
