Early full nursing helps patients with some dysfunctions speed up the reorganization of central nervous system functions and coordinate muscle and limb activities. Postdischarge continuation nursing for patients who have not fully recovered after being discharged from the hospital can transfer nursing work from the hospital to the family to meet their nursing needs. In this study, early full nursing combined with postdischarge continuation nursing was used for patients with traumatic brain injury to explore its efficacy and its impact on patients' motor function, quality of life, and complications. The results of the study show that the total effective rate of the observation group (95.92%) was higher than that of the control group (85.71%). At discharge and 1 month, 3 months, and 6 months after discharge, the upper limb Fugl-Meyer score, lower limb Fugl-Meyer score, ARAT score, FIM score, 4 dimensions of GQOLI-74 score, and Barthel index scores of the observation group were higher than those of the control group in the same period. The postoperative complication rate (10.20%) of the observation group was lower than that of the control group (26.53%). Early full nursing combined with postdischarge continuation nursing can improve the rehabilitation effect, effectively promote the recovery of motor function in patients with traumatic brain injury, improve the quality of life, and reduce postoperative complications.
