Patients with head injury need effective help. The restoration of disturbed ventilation and an impaired general circulation is important. Concomitant injuries, which occur in about 40% of cases, should be recognized. Priority must be given to treating large lesions of vital organs. Hypoxia and hypotension should be avoided because they produce secondary brain damage. Unconscious patients are intubated and ventilated. In a few cases a laryngeal mask could be applied. Intravenous hypnotics, narcotics and benzodiazepines are used. Inhalational anesthetics, among them N2O, are harmful and should be avoided in these cases. The patients are given normal volumes of colloid fluids or water electrolyte solutions. A long-lasting muscle relaxation will impede clinical assessment. Cerebral protection and effective drug treatment of the lesions is still under debate: Nimodepine in traumatic SAH and glucosteroids in local lesions with BBB rupture, however, seem to be effective.
头部受伤的患者需要有效的帮助。恢复紊乱的通气和受损的全身循环很重要。约40%的病例会出现合并伤,应予以识别。必须优先治疗重要器官的大损伤。应避免缺氧和低血压,因为它们会导致继发性脑损伤。昏迷患者需插管并进行通气。少数情况下可使用喉罩。使用静脉催眠药、麻醉药和苯二氮䓬类药物。包括氧化亚氮在内的吸入性麻醉药有害,在这些情况下应避免使用。给予患者正常量的胶体液或水电解质溶液。长时间的肌肉松弛会妨碍临床评估。脑保护和对损伤的有效药物治疗仍存在争议:然而,尼莫地平用于创伤性蛛网膜下腔出血,糖皮质激素用于血脑屏障破裂的局部损伤,似乎是有效的。
