Dex® carbohydrate drinks in trauma patients fasting preoperatively – A patient satisfaction study

Introduction: Dex® is an alkaline carbohydrate (CHO) drink used preoperatively in patients fasting for elective surgery. Its utilisation in patients awaiting emergency surgery is yet to be ascertained. We undertook a study assessing patient satisfaction relating to the introduction of Dex® in trauma patients in a Level 1 adult trauma centre. Methods: Patients fasting for surgery, and able to receive clear fluids in compliance with local guidelines, were eligible for inclusion. Patient satisfaction scores for predetermined variables were recorded via an interval observer scale prior to and following the introduction of Dex® to the trauma unit. Results: Prior to the introduction of Dex® 14 satisfaction evaluations were completed. A further 13 evaluations were returned after Dex® was made available. Post-traumatic amnesia accounted for some patients being unable to complete the evaluation. Patients who completed the satisfaction evaluations after Dex® was introduced reported higher satisfaction in all but two variables (‘Headache’ and ‘Staff Annoyance’). ‘Hunger’ median scores were 7 (95% CI, 5–8) prior to the introduction of Dex® and 3 (95% CI, 2–6) after its’ introduction (p =.004). ‘Thirst’ median scores were 7.5 (95% CI, 6–10) and 4 (95% CI, 3–8) prior to and after Dex® introduction, respectively (p =.018). Conclusion: No adverse events or theatre timing related issues were associated with the use of Dex®. A larger randomised study of CHO drink supplementation in trauma patients fasting preoperatively is warranted to further evaluate these satisfaction endpoints as well as the other variables investigated in this study. Postoperative evaluation of these markers should also be considered.
