Abstract

Thompson J (2011) Caring for critically injured soliders. Nursing Times; 107: 1, early on-line publication.

This article highlights the unique challenges faced by clinical staff caring for military casualties and identifies why routine clinical practice needs to be adapted to provide effective care.

The types of injury are discussed as well as pain management regimens, which have to be tailored to accommodate specific patterns of injuries.

Flashbacks and hallucinations are common problems following traumatic injury and affect each soldier differently. The need for psychological support is explored as this is one of the most challenging aspects of caring for military casualties and their families.

5 key points

1 It is important civilian nurses understand the pressues of working in a field hospital and patients’ experiences

2 Severe blast wounds can remain open for many weeks requiring regular monitoring and inspection. Surgical debridement may be needed every two to three days. Topical negative pressure can be a useful technique for these severe wounds

3 Rigorous infection control measures, including the use of full length protector gowns, are crutical to minimise the risk of cross infection

4 Military patients should be oriented to place and time as quickly as possible so injuries can be explained and understood

5 Staff support sessions are helpful because of the severity of injuries that they deal with and their impact on the patient and their family. Visits to the military rehabilitation centre can help staff to see patients progress in the longer term

Royal Centre for Defence Medicine

Military and NHS nurses have been working together at the Royal Centre for Defence Medicine (RCDM) following its relocation to University Hospitals Birmingham Foundation Trust in 2001. The move followed the closure of military hospitals in the UK.

The UHB was chosen because it was a regional burns and trauma centre and it was near to Birmingham International Airport.   All British military casualties and entitled personnel affiliated with the British Armed services are repatriated to this centre.

There are 42 military critical care nurses based across critical care services at the trust, as well as military staff working in various roles. The military nurses work with NHS staff.

It is important that civilian nurses understand the pressures of working in a field hospital and patients’ experiences.

The unit manager from Selly Oak critical care spent three months in 2009 working in the intensive care unit in the field hospital at Camp Bastion as part of Op HERRICK aided by the NHS Support to Operations initiative. During this visit, she was able to provide educational support for nurses involved in managing burns or major trauma. Following this, two more members of staff from critical carehave been to Camp Bastion.

This experience is invaluable not only for the individual nurses but also for the rest of the team as they receive feedback and see photographs of conditions in the ICU in Camp Bastion. This increased understanding between staff of their roles and encourages empathy towards military personnel and patients.

Managing the impact of injured troops in a civilian hospital 

It is important to highlight that UHB is unique in the number of injured military personnel it treats. On occasions our critical care unit has accommodated up to 11 critically injured military patients – the standard capacity of this unit is usually 15 - in addition to serving the Birmingham area.

Patients arrive directly at the unit and it is common for two or three injured soldiers to arrive together; on occasion, as many as six patients have been admitted at the same time. In this situation, organising critical care beds and staffing can be compared to managing a major incident procedure. Patients who are fit for discharge to the wards will be identified and extra beds will be opened where possible, with extra staffing provided by both the trust and military.

The trust and its staff have become an integral part of military operations and policies so, when plans are put in place for a new military operation, the trust has prior warning to allow forward planning. This means additional injured troops can be cared for while the trust continues to provide a full service to the people of Birmingham and surrounding areas.

Blood supplies

Support services within the trust, for example the blood transfusion service, have adapted their practice to meet the dynamic demand of caring for military personnel,

The multiple blood transfusions received by the soldiers in the hours following injury, in addition to frequent repeated transfusions, can lead to the development of antibodies. In these circumstances, patients need a fresh cross-match specimen every 24 hours.

If a number of critically injured military personnel are repatriated together, the requirement for blood products - for both planned surgical interventions and ad hoc transfusions - increases the laboratory workload. To meet this demand, staff in the blood bank are supported by three military biomedical scientists. If large amounts of blood are required overnight, the hospital’s supply of O-negative blood can be used; there is also a trauma technician on call who can prepare more blood in the event of an emergency.

Immediate care

Military patients admitted to UHB usually have battlefield injuries sustained as part of Op HERRICK in Afghanistan and previously Op TELIC in Iraq.

Injured soldiers are evacuated from the battlefield by the medical emergency retrieval team – comprised of doctors, nurses and paramedics – and taken to the nearest field hospital to be stabilised and receive emergency surgical intervention. Following assessment, arrangements for repatriation to the UK can begin.

Details of patient injuries and recent vital signs are faxed to RCDM along with estimated time of arrival. The critical care air support team (CCAST) is deployed from the tactical medical wing at RAF Lyneham to retrieve the patient. The team consists of two RAF ICU-trained nurses, a consultant anaesthetist, a medical technician and an RAF flight medic.

Specialist medical teams are notified in advance, including surgeons from trauma and orthopaedics, burns and plastics, general and cardiac and vascular. They are on standby for the patient’s arrival and extra theatre facilities are prepared for immediate use. Primary and secondary investigations, including CT scans carried out at the field hospital, are saved on a CD and transferred with the patient.

Once patients arrive at UHB and are stable the priority is to change all invasive lines using strict asepsis. After assessment by the relevant surgical teams, it is imperative that the patient goes to theatre for a thorough examination and treatment of all wounds. Traumatic amputations managed in the field hospital will require cleaning and revision to minimise potential necrosis and infection.

Injuries

Most injuries occur as a result of blasts sustained by an activated improvised explosive device (IED) commonly known as a landmine. Activation may have been by foot or vehicle and the mechanism will impact upon the severity of injuries sustained. Other injuries result from gun-shots, rocket propelled grenade (RPG) attacks and occasional road traffic collisions.

The most common injury resulting from an IED is traumatic or immediate surgical amputation of the legs. Shrapnel is blasted upwards and outwards and can cause extensive damage including abdominal injuries, trauma to upper limbs including amputation, extensive soft tissue damage or burns, bony fractures from being flung away from the blast and facial injuries including penetrating eye injuries.

Our experience of caring for soldiers with these wounds has been unlike any other group of patients. Despite being a regional trauma centre the wounded soldiers have provided a steep learning curve for all team members. Wounds need to be constantly inspected and remain open for long periods of time, often weeks after injury. The patient may require surgical debridement every 48 to 72 hours.

Managing open wounds between surgical episodes is challenging. Topical Negative Pressure (TNP) therapy has been widely used with chronic diabetic ulcers (Jones et al, 2005), but has been very successful with this patient group. Our experience with military personnel has led to further development of this equipment to treat large acute wounds – an advance in technology that is now available to all patients. This is illustrated in Fig 1. and Fig 2.

The types of wounds dressed with TNP vary from open stump wounds to open abdominal wounds; it is not uncommon for one patient to have all of these. The addition of external fixators for pelvic or leg fractures can further complicate these wounds, and skill is required to position the dressings to create a good seal for the vacuum (Fig 1.).

Infections

In the early phases of the Afghanistan war there was a high incidence of infection with multi-drug resistant (MDR)Acinetobacter in IED wounds, symptoms of which were evident by the time patients reached the UK. Acinetobacter is a Gram-negative bacterium that is found in drinking and surface waters, soil, sewage and various types of foods.

Isolating or cohorting these patients was important but several factors, including the number of infected patients and the high numbers of visitors prompted a revision of infection control policies in an attempt to minimise cross-infection. This was achieved by small changes, such as limiting the number of people entering a bed space to two at any one time. This change was prompted by large ward rounds – military ward rounds can have 11 clinicians at once. We have also demarcated bedspaces with lines on the floor to discourage staff from entering unless absolutely necessary, providing a physical reminder to put on an apron and gloves where appropriate.

The incidence of colonisation or infection of MDR Acinetobacter is less common now, but we still maintain precautions for at least seven days for all military patients on the critical care unit to allow any potential growth to be identified. In critical care, full-length protector gowns (including arms) are worn by all clinical staff examining military patients. The protector gowns are unpleasant to wear for long periods of time so the nurse caring for the patient wears an ordinary plastic apron in their own bedspace, and wears a protector gown if assisting in a non-infected bedspace, although this is discouraged where possible. If no multi-resistant infections have been isolated after seven days this higher level of personal protection can be stepped down.

Patterns of infection can be largely attributed to the area where military operations are being carried out. MDR Acinetobacter was more prevalent in the desert areas of Afghanistan; lately operations have moved to farmland areas, and again this is reflected in the clinical presentation of the wounded soldiers. All patients from this area will be immediately started on an anti-fungal regime and are reviewed daily by a consultant microbiologist.

Patients are screened for a variety of tropical diseases in addition to our routine screening programme and during malaria season (May to November) they will also receive anti-malarial prophylaxis for four weeks. 

Pain management

Many of the soldiers are amputees and neuropathic pain is a major problem. The acute pain team has developed a successful regime to accommodate these injuries. On the first day of their repatriation they are prescribed amitryptyline and pregabalin, and the dose is adjusted over time. These will be started even if the patient is sedated to allow a therapeutic level to be reached. In addition, they will also be prescribed regular paracetamol, tramadol, and possibly codeine. This regime is also helpful for brachial plexus injuries from gunshot wounds.

Sciatic nerve blocks have been used in the field hospital to manage pain associated with bilateral leg amputation with good results. These can be left place for three to four days and are helpful while waiting for the oral analgesic regime to take effect. Patient-controlled analgesia (PCA) is also helpful where the patients can use their hands.

Nutrition

Injured soldiers involved in active duty may have very little reserve to cope with the massive catabolism associated with critical injury.

Early nutrition is important and feeding will be started as quickly as possible following arrival at UHB. Where abdominal injuries are present and a considerable delay to feeding is expected alternatives, including total parenteral nutrition (TPN) are considered. Facial injuries may rule out nasal or oral feeding but alternative routes include per-gastric or jejunal feeding may be required.

All military personnel are started on a high protein feed, which is increased to full rate as quickly as possible following the trust’s enteral feeding policy. Enteral feeding continues throughout surgery and other interventions, where the patient is intubated and has a protected airway. Surgical spells can last eight hours or more, which is a significant period of time to be starved when already in a catabolic state.

Psychological care

The majority of military critical care patients are sedated and ventilated so our initial efforts focus on the psychological support of family members, some of whom have had to travel considerable distances and many have the added trauma of leaving young children with friends and family. Accommodation is provided in flats refurbished by the military specifically for this purpose, or in hotels. There is a wide military support network for the families, which is often referred to as the ‘Military Bubble’. The Defence Military Welfare Service is made up of civilians from the Red Cross and provides support to the next of kin and the immediate family. A visiting officer is nominated from the injured soldier’s unit to escort the next of kin to Birmingham and provide family support throughout the hospital stay. Military liaison officers based at RCDM Headquarters provide a vital link between the injured soldier and their unit.

The military duty critical care nurse has a vital role, offering a point of contact for families and provides the interface between welfare staff whilst the patient is unconscious.  Daily military patient activity report meetings are held to bring together the clinical, welfare and administrative patient care pathways to ensure maximum care and support. This meeting also plans onward rehabilitation and discharge planning with the rehabilitation coordinating officer and the military discharge coordinators.

Military nurse coordinators are also based at RCDM HQ. Their role is to obtain family contact details and try to develop a holistic care package for the injured soldier. They provide condition feedback at daily military meetings in order to begin rehabilitation and discharge plans. Condition feedback is also provided at the weekly joint telephone case conference, which is attended by military and civilian clinicians and includes the permanent joint headquarters at Camp Bastion and Kandahar, and Aeromedical Evacuation Control Centre at RAF Brize Norton. Patterns of injuries may be discussed in order to identify areas for improvement, for example, changes to body armour.

Patient diaries

Patient diaries are provided to all sedated critically injured military patients. Entries will begin as soon as possible in Camp Bastion and are written in everyday language. They are a useful tool for documenting key events and present an opportunity for visitors – colleagues and friends – to leave messages. There is evidence diaries can have a positive effect on psychological recovery from ICU experiences, allowing people to gain a sense of coherence following their critical illness (Engstrom et al, 2009).

Flashbacks and hallucinations

Patients may experience disorientation as they wake up from sedation and this may be accompanied by flashbacks of their experiences, the incident or colleagues being injured. There are degrees of flashbacks, from disorientation that simply require reassurance to more severe hallucinations. Patients may believe they are being held captive by the Taliban, groping for weapons or trying to jump out of bed to escape.

Sleep deprivation may be a problem as soldiers in the field usually only sleep for a few of hours at a time between watches, and must be hyper vigilant when on watch. Getting back into a good day to night sleeping pattern can have an impact on their psychological state in the acute phase of injury.

It is important that the soldiers are oriented to place and time as quickly as possible so injuries can be explained and understood; the loss of sight, for example could exacerbate feelings of fear and disorientation.

Where possible, family will be present to support the patient when the injuries are explained for the first time. Military community psychiatric nurses (CPNs) are available to provide support to the patients and ensure they receive their mandatory post operational stress debriefing.

Regardless of the severity of soldier’s flashbacks or distress at the situation they find themselves in, it is undoubtedly helped by seeing their colleagues – other soldiers with similar stories and injuries. Although we provide clinical treatment in ICU to aid their recovery, it is not until they go to the ward and spend time with other soldiers that their psychological recovery can really start. Getting back into their military routine also helps – having a haircut and shave, wearing the uniform or parts of it, helps to regain some of their old identity.

Staff support

Staff support is available to all members of the team caring for critical care patients because of the severity of the injuries they encounter and the intensity of emotions from family members. Staff develop a rapport with families making tough situations, such as the death of a soldier extremely difficult to accept. Staff support sessions from trust counsellors have had a good uptake, as well as  group sessions. Simply having the opportunity to discuss specific experiences, how they felt in that situation, and having support from other colleagues who also felt the same way has proved beneficial.

Visits to the Defence military rehabilitation centre at Headley Court boost staff morale by providing an opportunity to have an informal trip away from work, to catch up with former patients and observe their progress first-hand. Seeing patients months later learning to walk with prostheses and having a positive and determined outlook on life is wonderful. It is a real morale booster for staff, and in turn allows the nurses to chat with patients and their families about Headley Court and what it can offer them.

Conclusion

University Hospitals Birmingham NHS Foundation Trust has been a Trauma Centre for many years and is ideally suited to be the headquarters for the Royal Centre for Defence Medicine. Caring for injured military personnel brings unique challenges, which may never otherwise be experienced. The greatest challenge is the psychological and social impact of injury on the soldiers and their families, and knowing the difficulties that lie ahead for them. Ultimately, what these challenges bring is a sense of humility and pride that we are caring for our injured soldiers.

Supporting military casualties

  • Most war injuries occur as a result of blasts sustained by an activated improvised explosive device (IED), commonly known as a landmine.
  • Many of the soldiers are amputees and neuropathic pain is a major problem.
  • Injured soldiers require nutritional support to cope with the massive catabolism associated with critical injury.
  • Patient diaries are provided to all sedated critically injured military patients and help soldiers understand what has happened to them.
  • Patients may be disorientated as they wake up from sedation and this may be accompanied by flashbacks of their experiences, the incident or colleagues being injured.
  • Getting back into military routine helps rehabilitation– having a haircut and shave, wearing the uniform or parts of it, helps to regain identity.

 

Royal boost in morale

  • Visits from the royal family – their royal highnesses the Prince of Wales, Prince Edward, Prince William, and Prince Harry have all visited – help to boost morale among the patients and their families.
  • Having the chance to tell their story to people who genuinely care about what they have been through - knowing that they have taken time out of their busy schedules - means everything.
  • If a patient is sedated, a message will be left in their diary for them to read when they wake up.

  • I found this article very interesting informative and reassuring.It was valuable to me as both a nurse and mother of a soldier currently serving in Afghanistan, to know the level of care given to our injured soldiers. The person writing this article showed great compassion knowledge and enlightenment with the problems faced by all concerned. Like every mother hope my son never needs your care. But thanks to people like you, they get the very best chance of recovery.
