一种新型低温静脉输液装置对中枢性高热患者的降温效果及安全性研究

背景　物理降温方法是中枢性高热患者的主要降温方法，目前临床上常用的物理降温方法效果报道不一，且存在较明显的并发症。目的　探讨一种新型低温静脉输液装置（国家实用新型专利，专利号：ZL 2014 2 0070586.4）对中枢性高热患者进行物理降温治疗的效果及安全性。方法　选取2015-2019年佛山市中医院重症医学科收治的中枢性高热患者93例，采用随机数字表法将其分为对照组（n=29）、普通静脉降温组（n=32）和应用降温装置组（n=32）。对照组给予基础治疗及体表物理降温，普通静脉降温组在对照组的基础上予以静脉输注低温液体（由冰箱冷藏4 ℃），应用降温装置组则在对照组的基础上采用新型低温静脉输液装置输注室温液体。检测三组患者治疗前、治疗24 h及治疗48 h后的凝血功能指标：纤维蛋白原（FbgC）、活化部分凝血活酶时间（APTT）、凝血酶原时间（PT）及血小板计数（PLT）；观察寒战、心律失常、皮肤受损等并发症发生率；测量治疗前及治疗2、4、8、12、24、48 h的肛温；评估治疗1周后格拉斯哥昏迷量表（GCS）评分；电话随访患者治疗28 d病死率。结果　治疗方法和时间对FbgC、APTT、PT及PLT不存在交互作用（P>0.05）；治疗方法和时间对FbgC、APTT、PT及PLT主效应均不显著（P>0.05）。应用降温装置组寒战发生率低于对照组和普通静脉降温组，皮肤受损发生率低于对照组（P<0.017）。治疗方法和时间对肛温存在交互作用（P<0.05）；治疗方法和时间对肛温主效应均显著（P<0.05）；其中应用降温装置组治疗2、4、8、12、24、48 h的肛温均低于对照组和普通静脉降温组（P<0.05）。治疗1周后应用降温装置组GCS评分高于对照组和普通静脉降温组（P<0.05）。三组患者治疗28 d病死率比较，差异无统计学意义（P>0.05）。结论　采用新型低温静脉输液装置对中枢性高热患者进行物理降温治疗具有快速且稳定的降温效果，且其并发症发生率低，可广泛应用于临床降温治疗。     

Risk factors for children requiring adenotonsillectomy and their impact on postoperative complications: a retrospective analysis of 2000 patients

Adenotonsillectomies are commonly performed procedures and sleep-disordered breathing is becoming increasingly important as an indication for surgery. Because of the higher risks in patients with obstructive sleep apnoea, the required level of postoperative care for these patients is currently under discussion, and better identification of patients at risk may reduce unnecessary postoperative monitoring. To evaluate the influence of obstructive sleep apnoea, and other risk factors, on peri-operative complications in children requiring adenotonsillectomy, we performed a retrospective case-control study that included 1995 patients treated between January 2009 and June 2017. In our analysis, young age (OR 3.8, 95%CI 2.1–7.1), low body weight (OR 2.6, 95%CI 1.5–4.4), obstructive sleep apnoea (OR 2.4, 95%CI 1.5–3.8), pre-existing craniofacial or syndromal disorders (OR 2.3, 95%CI 1.4–3.8) and adenotonsillectomy, compared with adenoidectomy alone, (OR 7.9, 95%CI 4.7–13.1) were identified as risk factors for complications during or after surgery, p < 0.001. All 13 patients suffering from complications more than 3 h postoperatively had obstructive sleep apnoea plus at least one more of these risk factors. Patients at risk of postoperative complications can therefore be identified by several criteria pre-operatively, and should be monitored postoperatively using pulse oximetry overnight. For all other patients, postoperative observation on a surgical ward without extra monitoring is sufficient. Admission to paediatric intensive care should be reserved for patients suffering serious intra-operative complications.
