Feeding modality evolution in traumatic brain injury patients with severe alteration of consciousness: A observational study

The aim of this study was to compare feeding modalities and the level of consciousness in patients with a severe brain injury during reeducation and rehabilitation. The clinical data of vegetative state or minimal conscious state due to severe traumatic brain injury hospitalized in a coma arousal unit were collected from 2012 to 2019. Feeding modalities were evaluated clinically and with functional endoscopy evaluation of swallowing or video fluoroscopy and functional oral intake scale. Evolution of consciousness was evaluated using Wessex Head Injury Matrix scale (WHIM). Comparison between WHIM score and feeding modalities were performed at admission and at discharge of the arousal unit. Of the 93 patients considered, 33 were included corresponding to inclusion criteria (traumatic brain injury, disorder of consciousness and age > 18 years). The mean age was 44.8 +/- 16.8 years, and there were 6 females for 27 males. At admission, all patients were fed by gastrostomy (n = 25) or by nasogastric tube (n = 8) and 27 had a tracheostomy. At discharge, 10 patients keep an exclusive alimentation by gastrostomy (Group 1, G1) as 23 had exclusive oral feeding (Group 2, G2). The score of the WHIM at admission was identical in both groups (21.7 +/- 10.9 (G1) vs. 21.0 +/- 15.33 (G2) (ns)). At discharge, WHIM increased to 38.3 +/- 15.4 in G1 and to 49.8 +/- 9.7 in G2 (P <.05). WHIM score was significantly higher in G2 than in G1 (P <.05). There was a positive correlation between functional oral intake scale and WHIM at discharge. Our results demonstrated that recovery of oral feeding in patients with a severe traumatic brain injury appeared in those who had the better improvement of consciousness level.
