RESUMEN
BACKGROUND: Paroxysmal sympathetic hyperactivity (PSH) is a syndrome of excessive sympathetic activity, mainly occurring in severe traumatic brain injury. However, few studies have reported the frequency of PSH and its related risk factors in adult patients with brain injury. METHODS: We performed this systematic review and meta-analysis to estimate the combined incidence of PSH and the associated risk factors in adult patients with brain injury. This study was registered with the PROSPERO international prospective register of systematic reviews (https://www.crd.york. ac.uk/PROSPERO/Identifier: CRD 42021260493), and a systematic search was conducted of the scientific databases Embase, PubMed, Web of Science, Cochrane Library, and Google Scholar. All identified observational studies regarding the incidence and risk factors of PSH in adult patients with brain injury were included. Two authors extracted data independently; data were analyzed by STATA version 16. RESULTS: The search yielded 9 studies involving 1643 adult patients. PSH was detected in 438 patients. The combined incidence of PSH in adult patients with brain injury was 27.4% (95% confidence interval [CI], 0.190-0.358). The risk factors include patients' age (SMD = -0.592; I2 = 77.5%; 95% CI, -1.027 to -0.156; P = 0.008), traffic accident (odds ratio [OR], 1.783; I2 =18.0%; 95% CI, 1.128-2.820; P = 0.013), admission Glasgow Coma Scale score (SMD = -1.097; I2 =28.3%; 95% CI, -1.500 to -0.693; P = 0.000), hydrocephalus (OR, 3.936; I2 =67.9%; 95% CI, 1.144-13.540; P = 0.030), and diffuse axonal injury (OR, 4.747; I2 =71.1%; 95% CI, 1.221-18.463; P = 0.025) and were significantly associated with the presence of PSH after brain injury. CONCLUSIONS: PSH occurs in nearly a quarter of adult patients with brain injury. Patient's age, traffic accident, admission Glasgow Coma Scale score, hydrocephalus, and diffuse axonal injury were risk factors for PSH in adult patients with brain injury. These findings may contribute to novel strategies for early diagnosis and interventions that aid in the rehabilitation of patients with brain injury.

ABSTRACT: BACKGROUND: External ventricular drains (EVDs) are commonly used in neurosurgery. Preventing EVD-related infections is important, and nursing plays a significant role in infection control. However, because of the limited number of neurosurgical nurses and heavy workload in developing countries, well-trained patient care technicians (PCTs) might be able to assist nurses under this circumstance. METHODS: This study retrospectively screened patients who underwent EVD procedures in our medical center from January 2012 to June 2018. Clinical characteristics including EVD-related infection rates of patients with or without PCTs were compared. RESULTS: We analyzed 234 patients in total. There were 26 EVD infection cases, and the overall infection rate was 11.1%. There were 122 patients who were given additional care by PCTs. They were elder (58.1 ± 13.1 vs 49.9 ± 17.0 years old, P < .001) and had lower level preoperational Glasgow Coma Scale (7.04 ± 3.66 vs 13.5 ± 2.53, P < .001) and higher intubation rate (28.7% vs 3.6%, P < .001) than those without PCTs. They also had a longer drainage duration (10.3 ± 4.97 vs 8.01 ± 4.35, P < .001) as well as more cerebrospinal fluid sampling times (2.45 ± 2.00 vs 1.75 ± 1.83, P = .006) and were kept at artificial airway status for a longer duration (10.1 ± 18.7 vs 1.93 ± 7.86, P < .001). External ventricular drain-related infection rates were similar between 2 groups (11.5% vs 10.7%, P = .853). CONCLUSION: Patient care technicians with proper training are beneficial to the prevention of EVD-related infection as a measure of improving staffing adequacy.
