ABSTRACT
Objective:
To explore the epidemiological characteristics of patients with electrical burn at different voltages complicated by cerebral trauma, so as to provide a basis for improving the treatment level of such injury.Methods:
A retrospective cohort study was conducted to analyze the clinical data of 480 patients with electrical burn complicated by cerebral trauma treated in Qingdao Municipal Hospital affiliated to Qingdao University from January 2001 to December 2019. According to the voltage intensity, the patients were divided into low voltage group (injury voltage<1 kV, n=295) and high voltage group (injury voltage≥1 kV, n=185). Gender, age, status of burn and other general data of all patients were collected. The clinical manifestations, consciousness [Glasgow coma scale (GCS)], imaging findings, treatment, prognosis [Glasgow outcome scale (GOS)] and complications were compared between the two groups.Results:
(1) Gender and age the male to female ratio was 5.4∶1.0; the peak age of onset occurred at 18-60 years, accounting for 302 patients (62.9%); the status of burn the burn area ranged from 1%-78% [(20.0±4.0)%] total body surface area (TBSA), with the current outlet located at the head in 321 patients. (2) Clinical manifestations consciousness disorders accounted for the highest proportion, with 295 patients (100%) in low voltage group and 185 patients (100%) in high voltage group, followed by headache which occurred in 178 patients (60.3%) in low voltage group and 115 patients (62.2%) in high voltage group (all P>0.05). (3) Consciousness 37 patients presented coma, with 17 patients (5.8%) in low voltage group and 20 patients (10.8%) in high voltage group ( P<0.05). (4) Imagingfindings:
CT and MRI examination found cerebral edema, skull fracture, intracranial hematoma, cerebral ischemia, subarachnoid hemorrhage, and other positive lesions. In patients with head wounds (current inlet and outlet located in the head), the incidence of cerebral trauma was 44.0% in low voltage group and 86.8% in high voltage group ( P<0.05). In patients with no head wound (the current outlet was not located in the head), the incidence of cerebral trauma was 5.3% in low voltage group and 6.3% in high voltage group ( P>0.05). In contrast with the patients without current outlet locating in the head, there were three more types of cerebral trauma in patients with current outlet locating in the head, including skull fracture, intracranial hematoma and subarachnoid hemorrhage. (5) Treatment, prognosis and complications 478 patients (99.6%) received non-surgical treatment and 2 patients (0.4%) received surgical treatment. There was 1 death (0.2%) and 479 successfully treated patients (99.8%). The prognosis was good in 280 patients (94.9%), moderately disabled in 13(4.4%) and severely disabled in 2(0.7%) in low voltage group; while the prognosis was good in 143 patients (77.3%), moderately disabled in 30(16.2%), severely disabled in 11(5.9%) and death in 1(0.5%) in high voltage group (all P<0.01). After discharge, the incidence of numbness, paresthesia and anxiety was significantly higher in low voltage group than that in high voltage group (all P<0.01).Conclusions:
Male patients with electrical burn complicated by cerebral trauma are more than female patients, with the young and middle-aged population being at high risk. Disturbance of consciousness and headache are the main clinical manifestations. The incidence of high voltage coma is relatively higher. Compared with low voltage-induced electrical burn, the patients with high voltage-induced electrical burn complicated by cerebral trauma (current inlet and outlet located at the head) sustain more severe and extensive injury. Early and active CT or MRI examination is conducive to definite diagnosis. Non-surgical treatment is the main treatment. Compared with high voltage-induced electrical burn, the patients with low voltage-induced electrical burn complicated by cerebral trauma have significantly better prognosis, but are more likely to develop complications of numbness, paresthesia and anxiety.
