Objective:To investigate the effect of care bundles on prevention of nasal medical device-related pressure injury in patients with nasotracheal intubation undergoing oral and maxillofacial surgery under general anesthesia.Methods:This was a retrospective study. Using the convenient sampling method, patients with a surgical time more than 4 hours and a surgical grade of 3 or 4, with nasotracheal intubation undergoing oral and maxillofacial surgery under general anesthesia from Hospital of Stomatology, Sun Yat-sen University were selected. A total of 96 patients from July to December 2019 were in the control group, and 99 patients from July to December 2020 were selected as the observation group. The control group was treated with routine nursing measures, the observation group was subjected to a nursing care bundle. The incidence of nasal pressure injury was observed after the operation, 24, 48, 72 hours after the nasotracheal intubation was removed, and patients′ satisfaction score was compared.Results:The incidence of nasal pressure injury in the control group was 6.25% (6/96). None of the patients in the observation group had any pressure injury, which was significantly lower than the control group (Fisher exact probability method, P=0.013). The satisfaction scores in the observation group was significantly higher than that in the control group (26.88 ± 1.94 vs 24.71 ± 3.33), the difference was statistically significant ( t=-5.54, P<0.01). Conclusions:The care bundle can effectively prevent the occurrence of nasal pressure injury in patients undergoing oral and maxillofacial surgery with nasotracheal intubation and improve patient satisfaction.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.
