Lateral trauma position
The tradition of transporting trauma patients to hospital in a supine position may not be the safest approach in obtunded patients with unprotected airways. The ‘solution’ of having them on an extrication board (backboard / long spine board) to enable rolling them to one side in the event of vomiting may not be practicable for limited crew numbers.
The Norwegians have been including the option of the lateral trauma position in their pre-hospital trauma life support training for some years now.
A questionnaire study demonstrates that this method has successfully been adopted by Norwegian EMS systems.
The method of application is described as:
- Check airways (look, listen, feel).
- Apply chin lift/jaw thrust, suction if needed.
- Apply stiff neck collar.
- If the patient is unresponsive, but has spontaneous respiration: Roll patient to lateral/recovery position while maintaining head/neck position.
- Roll to side that leaves the patient facing outwards in ambulance coupé.
- Transfer to ambulance stretcher (Scoop-stretcher, log-roll onto stretcher mattress, or use multiple helpers, lifting by patient’s clothing).
- Support head, secure with three belts (across legs, over hip, over shoulder)
- Manual support of head, supply oxygen, observation, suction, BVM (big valve mask) ventilation when needed.
Different options for supporting the head in the lateral position, according to questionnaire responders, include:
- putting padding under the head, such as a pillow or similar item (81%)
- a combination of padding and putting the head on the lower arm (7%)
- rest the head on the lower arm alone (10%)
- rest the head on the ground (<1%)
BACKGROUND: Trauma patients are customarily transported in the supine position to protect the spine. The Airway, Breathing, Circulation, Disability, and Exposure (ABCDE) principles clearly give priority to airways. In Norway, the lateral trauma position (LTP) was introduced in 2005. We investigated the implementation and current use of LTP in Norwegian Emergency Medical Services (EMS).
METHODS: All ground and air EMS bases in Norway were included. Interviews were performed with ground and air EMS supervisors. Questionnaires were distributed to ground EMS personnel.
RESULTS: Of 206 ground EMS supervisors, 201 answered; 75% reported that LTP is used. In services using LTP, written protocols were present in 67% and 73% had provided training in LTP use. Questionnaires were distributed to 3,025 ground EMS personnel. We received 1,395 (46%) valid questionnaires. LTP was known to 89% of respondents, but only 59% stated that they use it. Of the respondents using LTP, 77% reported access to written protocols. Flexing of the top knee was reported by 78%, 20% flexed the bottom knee, 81% used under head padding. Of 24 air EMS supervisors, 23 participated. LTP is used by 52% of the services, one of these has a written protocol and three arrange training.
CONCLUSIONS: LTP is implemented and used in the majority of Norwegian EMS, despite little evidence as to its possible benefits and harms. How the patient is positioned in the LTP differs. More research on LTP is needed to confirm that its use is based on evidence that it is safe and effective.
