Decreased consciousness is a common reason for presentation to the emergency department (ED) and admission to acute hospital beds. In trauma, a Glasgow Coma Scale score (GCS) of 8 or less indicates a need for endotracheal intubation. Some advocate a similar approach for other causes of decreased consciousness, however, the loss of airway reflexes and risk of aspiration cannot be reliably predicted using the GCS alone.
A survey of all poisoned patients with a decreased GCS who were admitted to an ED short-stay ward staffed by experienced emergency physicians, to establish the incidence of clinically significant aspiration or other morbidities and endotracheal intubation.
A prospective, observational study was conducted of all patients admitted to the ED short-stay ward with a decreased level of consciousness (GCS < 15).
The study included 73 patients with decreased consciousness as a result of drug or alcohol intoxication. The GCS ranged from 3 to 14, and 12 patients had a GCS of 8 or less. No patient with a GCS of 8 or less aspirated or required intubation. There was one patient who required intubation; this patient had a GCS of 12 on admission to the ward.
This study suggests that it can be safe to observe poisoned patients with decreased consciousness, even if they have a GCS of 8 or less, in the ED.
意识下降是患者前往急诊科就诊及入住急性病床位的常见原因。在创伤患者中,格拉斯哥昏迷量表(GCS)评分8分及以下表明需要进行气管插管。一些人主张对其他导致意识下降的原因采用类似方法,然而,仅使用GCS无法可靠预测气道反射丧失和误吸风险。
对所有入住由经验丰富的急诊医生负责的急诊科短期病房、GCS评分下降的中毒患者进行调查,以确定具有临床意义的误吸或其他发病率以及气管插管的发生率。
对所有入住急诊科短期病房且意识水平下降(GCS<15)的患者进行前瞻性观察研究。
该研究纳入了73例因药物或酒精中毒导致意识下降的患者。GCS评分范围为3至14分,12例患者的GCS评分在8分及以下。没有GCS评分8分及以下的患者发生误吸或需要插管。有1例患者需要插管;该患者入院时GCS评分为12分。
本研究表明,在急诊科观察意识下降的中毒患者是安全的,即使他们的GCS评分在8分及以下。
