目的:通过对高胆红素血症新生儿换血前后血生化、甲状腺功能变化的检测,探讨其原因。方法:分别对17例高胆红素血症新生儿换血前后血常规、电解质、血糖及甲状腺功能等指标进行检测。结果:本组血清总胆红素和间接胆红素换血前、后有明显下降。换血后血电解质血钾降低,血钠、血钙升高,血糖暂时性升高,但在24 h内自行恢复至正常。可有贫血,白细胞及血小板明显下降,甲状腺功能变化没有显著性意义(Pgt;0.05),无明显并发症发生。结论:换血后可出现低钾、高钙、高钠、高血糖、低白细胞和血小板血症的发生,应预防感染、出血和电解质紊乱的发生。
During the medical rescue after Wenchuan earthquake, based on the design and implementation of the management process of blood purification equipment, we gave the top priority to those patients with post-disaster crush syndrome to ensure their hemodialytic treatment. Through strict management of blood purification technology, the outcomes of these patients have been fundamentally improved and the incidence of complications was substantially reduced. Safe and effective hemodialytic treatment have been administered to 77 patients with crush syndrome (813 case-times).
ObjectiveTo observe the clinical effect of microincision vitreoretinal surgery (VRS) assisted with intravitreal injection of ranibizumab (IVR) in severe proliferative diabetic retinopathy (PDR) treatment. MethodsThis is a prospective non-randomized controlled clinical study. A total of 60 patients (70 eyes) with severe PDR diagnosed were enrolled and divided into IVR group (31 patients, 35 eyes) and control group (29 patients, 35 eyes). IVR group patients received an intravitreal injection of 0.05 ml ranibizumab solution (10 mg/ml) first, and 3 or 4 days later they received 23G microincision VRS. Control group patients only received 23G microincision VRS. The follow-up time was 3 to 12 months with an average of (4.5±1.8) months. The logarithm of the minimal angle of resolution (logMAR) best corrected visual acuity (BCVA), intraocular pressure, the central retinal thickness (CRT) and retinal reattachment, and the incidence of postoperative complications were comparatively analyzed. ResultsThere was no topical and systemic adverse reactions associated with the drug after injection in IVR group. The incidence of post-operative vitreous hemorrhage (VH) in IVR group and control group was 8.6% and 28.6% at 1 week after surgery, 0.0% and 17.1% at 1 month after surgery, 0.0% and 8.6% at 3 month after surgery respectively. The differences were statistically significant for 1 week (χ2=4.63, P < 0.05) and 1 month (χ2=4.56, P < 0.05), but was not statistically significant for 3 months (χ2=0.24, P > 0.05). The mean post-operative logMAR BCVA of IVR group (0.81±0.40) and control group (1.05±0.42) have all improved than their pre-operative BCVA, the difference was statistically significant (t=12.78, 4.39; P < 0.05). The mean logMAR BCVA of IVR group is higher than BCVA of control group, the difference was statistically significant (t=-2.36, P < 0.05). The average post-operative CRT in IVR group was thinner than that of control group, the difference was statistically significant (t=-2.53, P < 0.05). The incidence of a transient high intraocular pressure in IVR group (14.3%) was lower than that in control group (34.3%), the difference was statistically significant (t=4.79, P < 0.05). The incidence of retinal reattachment (t=0.35), epiretinal membrane (χ2=0.97), neovascular glaucoma (χ2=0.51) was no difference between these two groups (P > 0.05). ConclusionThe minimally invasive VRS assisted by IVR treatment for severe PDR can effectively prevent postoperative VH, reduce CRT and improve visual acuity.
