117 ECHOCARDIOGRAPHY, PERFORMED DURING DAMAGE CONTROL RESUSCITATION, CAN BE USED TO MONITOR THE HAEMODYNAMIC RESPONSE TO VOLUME INFUSION IN THE DEPLOYED MILITARY CRITICAL CARE UNIT

Deployed military general internal physician’s toolkit: the recent past and near future

Introduction

The role of the military physician in Deployed Hospital Care involves the diagnosis and management of a wide variety of disease states. Broad clinical skills need to be complemented by judicious use of a limited array of investigations. No study has specifically quantified what investigations physicians use on operations.

Methods

A retrospective cross-sectional study was performed to ascertain what investigations were undertaken on all patients managed by the General Internal Medicine teams over a 14 month period during a recent enduring operation in Afghanistan. A record was also made of investigations that were unavailable but considered desirable by the treating physician in order to inform clinical or occupational decisions.

Results

676 patients were admitted during the study period. Blood tests were performed in 96% of patients, plain radiographs in 50%, CT in 12% and ultrasound in 12%. An ECG was performed in over half (57%) and a peak flow in 11%. The most desirable, but unavailable, investigations were cardiac monitoring and echocardiography (24% and 12% of patients, respectively).

Discussion

The data produced by this study both identified and quantified the investigations used by physicians during a mature operational deployment. This can be used in addition to accurate medical intelligence to inform and rationalise the diagnostic requirements for future operations as well as the provision of training. Technological advancements, particularly in weight and portability, are likely to enable more complex investigational modalities to be performed further forward on military deployments.
