Hypoxia and other factors are related to cognitive impairment. Hyperbaric oxygen therapy can improve tissue oxygen supply to improve brain hypoxia. Based on the basic principle of hyperbaric oxygen therapy, hyperbaric oxygen has been widely used in recent years for cognitive impairment caused by stroke, brain injury, neurodegenerative disease, neuroinflammatory disease and metabolic encephalopathy. This article will review the basic mechanism of hyperbaric oxygen, and summarize and discuss the improvement of hyperbaric oxygen therapy on cognitive and brain diseases, in order to provide relevant reference for clinical treatment.
目的:探讨颅脑损伤患者术中急性脑膨出的病因、诊断及治疗。方法:对127例术中发生急性脑膨出的颅脑损伤患者的临床资料进行回顾性分析。结果:急性脑膨出的原因为同侧脑肿胀者74例,为对侧迟发性血肿者51例,而为同侧迟发性血肿者2例。共死亡48例(37.8%),其中31例因脑疝死亡。结论:通过钻孔探查或积极的CT扫描,及时发现颅脑损伤患者术中急性脑膨出的原因,并尽早正确处理极其重要,是抢救此类患者成功的关键。
目的:探讨脑损伤患者凝血功能水平与颅脑损伤伤情转归的相关性。方法:收集70例颅脑损伤患者的临床资料,伤者抽取静脉血2 mL,进行凝血功能检测,分析结果与临床资料等分别采用SPSS 11.5软件进行χ2检验和logistic回归分析。结果:在13例凝血功能异常患者中有5例(38%)伤情加重(较入院时脑内血肿体积增大,迟发性血肿等),明显高于凝血功能正常而伤情加重者(12%,Plt;0.05);单因素和多因素logistic回归分析提示凝血功能异常时脑损伤伤情加重的危险因素。结论:脑创伤后凝血功能异常时颅脑损伤患者伤情加重的危险因素。
ObjectiveTo study the brain tissue oxygen and prognosis index of the postoperative patients with hypertensive intracerebral hemorrhage (HICH) associated with secondary brain insults. MethodsA total of 120 patients with HICH from January 2006 to June 2013 were treated by neurosurgical intervention. Postoperative monitoring of factors affecting the secondary brain insults in the 120 patients and of brain tissue oxygen in 10 patients was performed and statistically analysis was carried out. ResultsSecondary brain insults had a significant influence on the prognosis of postoperative patients with hypertensive intracerebral hemorrhage, and was correlated with brain tissue oxygen metabolism. ConclusionAbnormal secondary brain insults affect brain tissue oxygen metabolism, which may further deteriorate the brain damage and can lead to poor prognosis.
ObjectiveTo investigate the value of adaptive support ventilation (ASV) plus lung recruitment maneuvers (LRM) for patients with traumatic brain injuries combined with ARDS. MethodsThirty trauatic brain injuried patients combined with ARDS including 18 males and 12 females at age of 15-76 years were mechanically ventilated by SIMV+PSV or ASV+LRM.The patient was initially ventilated with SIMV for 8 hours,with tidal volume(VT)of 8 mL/kg,PEEP=0,oxygen inhalation concentration of 60%.Then,one of ASV+LRM and SIMV modes was randomly selected for continual ventilation.The positive end-expiratory pressure were set at three levels (PEEP 0,5 and 10 cm H2O).Each level of PEEP was maintained for 60 minutes.During the use of ASV+LRM,pressure controlled ventilation (PCV) was at 40 cm H2O and breath holding continued for 30 seconds.Then,the mode was turned to ASV.Respiratory mechanics,hemodynamics,blood gas,oxygen delivery,intracranial pressure and other indicators were measured when each level of PEEP was ventilated for 50 minutes. ResultsCompared with SIMV mode in the same level of PEEP,ASV+LRM mode had lower peak inflating pressure (PIP),airway plate pressure(Pplat) and intrapulmonary shunt(Qs/Qt),central venous pressure(CVP),intracranial pressure(ICP),but higher oxygenation index (PaO2/FiO2) and partial pressure of oxygen (PaO2)(all P<0.05).There was no statistical difference in MAP between two modes (P>0.05). ConclusionASV+LRM mode is better than SIMV in ventilation for traumatic brain injuried patients combined with ARDS.
目的:分析重型颅脑损伤患者早期进入ICU进行监护和治疗对预后的影响。方法: 将重型颅脑损伤患者根据是否直接进入ICU分为研究组和对照组,评价3月后患者神经功能和死亡率。结果: 与对照组比较,研究组死亡率更低,3月后ADL分级法生存质量良好率也显著更高。结论: 重型颅脑损伤患者早期进入ICU监护和治疗,可降低术后病死率,改善生存质量。
目的:总结分析1387例重型颅脑损伤的救治情况，以利在今后的工作中进一步改善和提高对重型颅脑损伤的救治水平。方法:回顾性分析1983年1月～2008年1月间1387例重型颅脑损伤患者的救治情况。结果:1387例重型颅脑损伤患者，其中手术治疗857例，非手术治疗530例。按GOS评分，出院时恢复良好475例（34.2%），中残206例（14.8%），重残202例（14.5%），植物生存89例（6.4%），死亡415例（29.9%）。结论:重型颅脑损伤仍然具有较高的病死率和致残率，早期及时手术清除颅内血肿，解除脑疝以及采取积极恰当的综合治疗措施是抢救治疗成功的关键。
