Amyotrophic lateral sclerosis (ALS) is a disease with progressive muscle weakness, also affecting respiratory muscles. In the terminal phase most patients experience a progression. Nutrition, speech and breathing capacity decrease. It is important to inform the patient and relatives in time and to give them a chance to decide. "Care Planning" and "Advance Directives" especially concerning ventilation reduces fear and helps the doctors and carers to decide, following the will of the patient. Nobody knows the speed of the progression. The patient in this case had few subjective symptoms at the time of the family conference. Progression till death lasted one month only. Treatment of his dyspnoe was not optimised, but during care all decisions were based on the actual will of the patient. Generally nocturnal hypoventilation, for instance non-invasive ventilation by BiPAP-mode, can relieve symptoms of dyspnoe in ALS patients. Low-dose morphine and/or benzodiazepine relieve respiratory discomfort and remove the negative spiral of dysnoe-fear-dyspnoe. Oxygen therapy is usually not needed (only in the very last stages of the disease) and is not recommended especially during the night. Hypercapnia can occur because of hypoventilation. This can cause growing unconsciousness and maybe death during sleep. Prolonging life is only possible by invasive long-term ventilation with all the problems of intensive care measures. The patient could have been given low dose morphine from the time of the family conference. Ventilation by CPAP-mode was insufficient for him.
肌萎缩侧索硬化症(ALS)是一种导致进行性肌肉无力的疾病,也会影响呼吸肌。在终末期,大多数患者病情会进展。营养、言语和呼吸能力都会下降。及时告知患者及其亲属并让他们有机会做出决定很重要。“护理计划”和“预先指示”,尤其是关于通气的内容,可减少恐惧,并有助于医生和护理人员根据患者的意愿做出决定。没有人知道病情进展的速度。在这次家庭会议时,该患者几乎没有主观症状。直至死亡的病情进展仅持续了一个月。对他的呼吸困难的治疗并未优化,但在护理过程中,所有决定都是基于患者的实际意愿做出的。一般来说,夜间通气不足,例如通过双水平气道正压通气(BiPAP)模式进行无创通气,可以缓解ALS患者的呼吸困难症状。低剂量吗啡和/或苯二氮䓬可缓解呼吸不适,并消除呼吸困难-恐惧-呼吸困难的恶性循环。通常不需要进行氧疗(仅在疾病的最后阶段),尤其不建议在夜间进行。通气不足可能会导致高碳酸血症。这可能会导致意识逐渐丧失,并可能在睡眠中死亡。只有通过侵入性长期通气并伴随重症监护措施的所有问题,才有可能延长生命。从家庭会议之时起就可以给患者使用低剂量吗啡。持续气道正压通气(CPAP)模式的通气对他来说并不足够。
