A systematic review of the prevalence of postamputation and chronic neuropathic pain associated with combat injury in military personnel

Management of critically ill patients in austere environments: good clinical practice by the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI)

The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) has developed a good clinical practice to address the challenges of treating critically ill patients in resource-limited austere environments, exacerbated by recent pandemics, natural disasters, and conflicts. The methodological approach was based on a literature review and a modified Delphi method, which involved blind voting and consensus evaluation using a Likert scale. This process was conducted over two rounds of online voting. The document covers six critical topics: the overall impact of austere conditions on critical care, airway management, analgesia, bleeding control, vascular access, and medical devices and equipment. In these settings, it is vital to apply basic care techniques flexibly, focusing on immediate bleeding control, airway management, and hypothermia treatment to reduce mortality. For airway management, rapid sequence intubation with ketamine for sedation and muscle relaxation is suggested. Effective pain management involves a multimodal approach, including patient-controlled analgesia by quickly acting safe drugs, with an emphasis on ethical palliative care when other options are unavailable. Regarding hemorrhage, military-derived protocols like Tactical Combat Casualty Care significantly reduced mortality and influenced the development of civilian bleeding control devices. Establishing venous access is crucial, with intraosseous access as a swift option and central venous access for complex cases, ensuring aseptic conditions. Lastly, selecting medical equipment that matches the specific logistical and medical needs is essential, maintaining monitoring standards and considering advanced diagnostic tools like point-of-care ultrasounds. Finally, effective communication tools for coordination and telemedicine are also vital.

Early versus delayed lower extremity amputations caused by firearm injury: A minimum 2-year follow-up

BACKGROUND

High-energy casualties such as firearm injuries may result in extensive loss of soft tissue and bone in the lower extremities. Although the primary aim in these types of injuries is the preservation of the extremity, repeated surgical procedures for extremity salvage and subsequent restoration of function could have detrimental effects on the patient both physically and psychologically. The main aim of this study is to evaluate the physical and psychological outcomes of patients who underwent lower extremity amputation in the early period after a firearm injury compared with the results of patients who underwent amputation in the late period. We also evaluated the factors affecting the prognosis in patients undergoing late below-knee amputation (BKA).

METHODS

This retrospective study included patients who underwent BKA following a lower extremity injury caused by firearms between March 2016 and March 2022. Patients who underwent emergency BKA at the first center they were taken to immediately after the injury constituted the early amputation (EA) group. Patients who were transferred to our tertiary-level referral center for continuation of treatment after the first intervention at another center and later underwent BKA constituted the late amputation (LA) group. The patients were evaluated regarding age, gender, amputation side, presence of phantom limb pain (PLP), and post-traumatic stress disorder (PTSD).

RESULTS

Information was available from hospital records for a total of 35 patients; 16 in the EA group and 19 in the LA group. All patients were male. The mean age at the time of injury was 25.5±5.3 years (range, 20-45 years), and the mean follow-up period was 37±17 months (range, 25-84 months). In the comparison of PLP experienced, the difference between the groups was statistically significant, with PLP experienced by 1 (10%) patient in the EA group and by 9 (90%) in the LA group (p=0.010). PTSD was diagnosed in 3 (23%) patients in the EA group and 10 (77%) patients in the LA group (p=0.039).

CONCLUSION

Patients who underwent late BKA were found to be affected by PLP and PTSD at a higher rate. When deciding on extremity-preserving surgery for patients with severe open injuries to the lower extremity, it is crucial to consider the poor outcomes associated with late BKA. Patients should be thoroughly informed about these negative outcomes.

Pain after combat injury in male UK military personnel deployed to Afghanistan

BACKGROUND

Chronic pain after injury poses a serious health burden. As a result of advances in medical technology, ever more military personnel survive severe combat injuries, but long-term pain outcomes are unknown. We aimed to assess rates of pain in a representative sample of UK military personnel with and without combat injuries.

METHODS

We used data from the ADVANCE cohort study (ISRCTN57285353). Individuals deployed as UK armed forces to Afghanistan were recruited to include those with physical combat injuries, and a frequency-matched uninjured comparison group. Participants completed self-reported questionnaires, including 'overall' pain intensity and self-assessment of post-traumatic stress disorder, anxiety, and depression.

RESULTS

A total of 579 participants with combat injury, including 161 with amputations, and 565 uninjured participants were included in the analysis (median 8 yr since injury/deployment). Frequency of moderate or severe pain was 18% (n=202), and was higher in the injured group (n=140, 24%) compared with the uninjured group (n=62, 11%, relative risk: 1.1, 95% confidence interval [CI]: 1.0-1.2, P<0.001), and lower in the amputation injury subgroup (n=31, 19%) compared with the non-amputation injury subgroup (n=109, 26%, relative risk: 0.9, 95% CI: 0.9-1.0, P=0.034). Presence of at least moderate pain was associated with higher rates of post-traumatic stress (RR: 3.7, 95% CI: 2.7-5.0), anxiety (RR: 3.2, 95% CI: 2.4-4.3), and depression (RR: 3.4, 95% CI: 2.7-4.5) after accounting for injury.

CONCLUSION

Combat injury, but not amputation, was associated with a higher frequency of moderate to severe pain intensity in this cohort, and pain was associated with adverse mental health outcomes.
