Major complications of functional endoscopic sinus surgery

The results of a postal questionnaire indicate an exponential rise in the practice of functional endoscopic sinus surgery (FESS) in the UK and a major complication rate of 0.23%. Cerebrospinal fluid leak was the most common serious complication accounting for 24 of the 36 reports.     

Effect of neurotensin and epinephrine on sinus arrhythmia caused by burst stimulation of the vagus nerve

Administration of neurotensin against the background of sinus arrhythmia caused by burst stimulation of the vagus nerve in cats restores synchronization of the cardiac and vagal rhythms or modulates the proportion between them. This either stops the arrhythmia or changes its parameters. The effects of the peptide are similar to those of epinephrine and are abolished by β-adrenoreceptor blockage.

经食道心房调搏测定窦房结功能

对27例病窦综合征患者和42例正常对照组,经食道心房调搏,测定窦房结功能。发现病窦患者,窦房结恢复时间>1450ms;校正窦房结恢复时间≥550ms;窦房结传异时间>191ms;固有心率均明显低于正常对照组(R<0.01)。用阿托品,心得安进行功能性植物阻滞前、后观察,发现阻滞后各次参数在正常对照组中有明显降低,而病窦组则无明显差异。实验证明,经食道心房调搏方法是无创性窦房结功能检查的有效方法。     

蝶塞及毗邻关系的解剖对蝶窦手术重要性探讨

蝶窦居于颅底，毗邻结构复杂，常有变异。本文报告开展各类型蝶窦手术１２５例，并就蝶窦区域应用解剖对蝶窦手术的重要性，进行研究与探讨。     

脑静脉血栓病人的死亡因素分析(附5例分析)

目的分析脑静脉血栓(CVT)病人的死亡原因。方法回顾分析136例CVT病人中5例死亡病例的病因、临床表现、影像学资料、治疗经过及死亡原因。结果病死率为3.7%。2例在急性期死亡,3例在慢性期死亡。直接死亡因素均为脑疝;间接死亡因素为颅内多发性出血和多个部位的脑静脉血栓形成,死亡组(3.20±0.84)支静脉受累,存活组(2.09±1.00)支静脉受累(P=0.016)。而性别、年龄、确诊时间、癫疒间发作、病灶部位及治疗前颅内压等没有显著增加死亡的危险性。某些临床表现,如失语、运动障碍、精神症状及意识障碍与死亡有关,但其系多发性颅内出血及多个部位脑静脉血栓所致。结论CVT病人的直接死亡原因为脑疝,间接原因为多发性脑静脉血栓和颅内多发性出血。死亡不仅可以发生在急性期,也可以出现在慢性期。     

Sinoatrial Node Electrogram Studies in Patients with Sick Sinus Syndrome

Sinoatrial node electrogram (SNE) was recorded successfully in recent years, using transvenous electrode catheter. Via SNE and intratrialelectrogram (IEG), one could measure sinoatrial conduction time(SACT) directly, observe sinoatrial node (SN) potential changes in cadiac cycles, diagnose some sinus arrhythmias which couldn't be confirmed by surface ECG. All these could offer accurate evidence for differential diagnosis of sick sinus syndrome (SSS). The authors recommend a modified method for the location of the electrode catheter, by which one can increase success rate of obtaining stable SNE. Using this method, the authors recorded SNE in 10 cases with SSS successfully.
