Objective To investigate the application of pediatric early warning score (PEWS) in neurology department.Methods The clinical data and PEWS of 1,158 children with neurologic diseases (764 febrile seizures,259 viral encephalitis and 135 bacterial meningitis) admitted into neurology department from August 2013 to November 2016 were analyzed retrospectively.PEWS was compared among the three different diseases.According to the disease severity,cases were categorized into no-monitor-required group (n =996,697 febrile seizures,203 viral encephalitis and 96 bacterial meningitis),monitor-required group (n =138,67 febrile seizures,41 viral encephalitis and 30 bacterial meningitis) and PICU group (n =24,0 febrile seizures,15 viral encephalitis and 9 bacterial meningitis).PEWS was assessed at admission in both no-monitor-required group and monitorrequired group.PEWS was recorded 12 hours before PICU transfer in PICU group.Then PEWS was compared among all groups in different diseases respectively.Results The median (minimum ～ maximum) of PEWS in febrile seizures,viral encephalitis and bacterial meningitis was 0 (0 ～ 3),2(0 ～ 8) and 2(0 ～ 8),respectively and there was significant difference among three diseases (P ＜ 0.01).No patient of febrile seizures was transferred to PICU.PEWS of febrile seizures in monitor-required group was higher than that in no-monitor-required group (P ＜ 0.01).For both viral encephalitis and bacterial meningitis,PEWS in monitor-required group was higher than that in no-monitorrequired group,and the score in PICU group was higher than that in monitor-required group.The difference was significant (P ＜ 0.01).Conclusion PEWS is effective for the assessment of illness severity of hospitalized children in neurology department,and can be used for the prediction PICU transfer as an excellent screening tool.

Objective To compare the therapeutic effect of conventional treatment and conventional treatment plus external application of Shuangbai Powder for patients with wounded limb injured by venomous snake. Methods One hundred patients bitten by venomous snake were randomized into treatment group and control group, 50 cases in each group. The control group was given conventional treatment including repeatedly washing the wound with hydrogen peroxide, debriding the wound, letting blood and draining toxicity, local blocking with chymotrypsin, wet packing the wounded limb with magnesium sulfate, and injection with anti-venomous serum, tetanus antitoxin, antibiotics, furosemide and energy mixture. The treatment group was given external application of Shuangbai Powder on the basis of the treatment for the control group. Both groups were given the comprehensive nursing of psychological nursing, wound nursing, dietary nursing, defecation nursing and functional nursing. The swelling-subsiding time for the wounded limb and pain scores of visual analogue scale (VAS) in the two groups were compared. Results(1) After treatment, swelling-subsiding time for the wounded limb of the treatment group was shorter than that of the control group, the difference being statistically significant (P < 0.05). (2) After treatment for 4 days and at the end of the treatment, VAS scores of the two groups were decreased compared with those before treatment(P < 0.05), and the decrease of VAS scores in the treatment group after treatment for 4 days was superior to that in the control group (P < 0.05). Conclusion The conventional treatment plus external application of Shuangbai Powder is an effective therapy for patients with wounded limb injured by venomous snake by shortening swelling-subsiding time and relieving pain for the wounded limb .

Objective To analyze the recurrence rate of intubation and increase of ventilator support rate within 24 hours after using fiberoptic bronchoscopy (FOB) in critically ill patients with hypoxemia complicated with respiratory failure, and to approach the feasibility of FOB in such patients.Methods A prospective study was conducted, including 200 critically ill patients with acute respiratory failure using FOB [oxygenation index (PaO2/FiO2) ≤ 300 mmHg (1 mmHg = 0.133 kPa)] admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Xinxiang Medical College. The rates of intubation and increased ventilatory support and the reasons for bronchoscopy related complications after using FOB 24 hours were recorded, the main risk factors leading to these changes and complications were analyzed and screened by logistic regression analytic method.Results Within 24 hours after using FOB for 200 patients with respiratory failure, an increase in mechanical ventilatory support was required in 68 patients (34%) of that 28 (14%) led to endotracheal intubation. With the extension of time, the rates of intubation and ventilatory support showed a tendency of elevation, the rise in ventilatory support rate being faster. The reasons for bronchoscopy related complications after FOB consisted of cardiovascular disease (41%), coronary artery disease (17%), chronic obstructive pulmonary disease (COPD, 17%), chronic restrictive pulmonary disease (10%), immunity suppression (54%), malignant neoplastic hematologic disorder (20%), acquired immune deficiency syndrome (AIDS, 12%), solid organ transplantation (3%), solid tumor (10%), corticosteroid therapy (25%), immunosuppressive drug (16%), diabetes (15%), chronic renal failure (14%), swallowing nerve injury (37%), anticoagulant therapy (19%), antiplatelet therapy (13%). In the patients with occurrence of COPD or immunosuppression, the rate of invasive ventilation used was significantly higher than that without using invasive ventilation [COPD: 35% (10/28) vs. 14% (24/172),χ2 = 8.081,P = 0.004; immunosuppression: 75% (21/28) vs. 50% (86/172),χ2 = 6.051,P = 0.014]. The logistic regression analysis showed that the occurrence of COPD or immunosuppression was obviously related to whether the intubation being necessary or not [COPD: odds ratio (OR) = 5.200, 95% confidence interval (95%CI) = 1.500 - 17.700,P = 0.006; immunosuppression:OR = 5.300, 95%CI =1.600 - 17.100,P = 0.004].Conclusions In patients with hypoxemia using FOB, they often require addition of mechanical ventilatory support, but the intubation rate is not high. Under the ventilatory support, FOB has certain feasibility for treatment of critically ill patients with hypoxemia and acute respiratory failure.
