譯者按：在病人接受醫院的急癥和急救服務前，全科醫生可能是首先接觸緊急狀態病人的醫生。創傷昏迷是常見的緊急狀態之一，通常病人無法通過語言交流來闡述病情，醫生可以通過間接的信息來源，并借助神經學檢查，如格拉斯哥昏迷量表，來初步判斷損傷的部位和嚴重程度，以便及時處理和轉送病人。

1　病史

張某是一位62歲的男性病人，他的幾個朋友把他送到急診室。他喝得爛醉，可能是摔倒在人行道上受傷了。在他摔倒受傷前，他找人吵架，還跟兩個年輕人打起來了。他的朋友跟你說，張某以前是一個很和藹可親和聰明的公務員，不過他很喜歡豪飲，特別是啤酒和烈酒。朋友們現在最擔心的是，張某一反常態，思維混亂，而且不能正常地走路。在他跌倒前大約1個小時，張某還在跟朋友交談，開始的時候談得還算正常，可是他逐漸地變得越來越煩躁，容易生氣，語無倫次，讓人無所適從。

2　體檢

張某看上去病得不輕。主要是表面上的擦傷，不過他渾身散發濃烈的酒氣。他說話語無倫次、含糊不清、雜亂無章。他的頭皮有一處撕裂，左側面部、頸部和雙臂有挫傷。

他的生命體征：脈搏64次/min，血壓140/90 mm Hg(1 mm Hg=0.133 kPa)，呼吸14次/min。他當時的狀況無法進行心理狀態測驗。他對口令不做出反應，比如讓他睜開雙眼。在他耳邊大聲問話，他嘴里嘟嘟囔囔的不知道在說什么。不過他對疼痛刺激(在眉弓上電刺激)有反應，他會睜開雙眼，躲開刺激。

3　提問

3.1你懷疑這個病人有哪些問題?

3.2根據對他意識狀態的客觀評價〔a 根據5個意識程度的分類；b 根據格拉斯哥昏迷量表(Glasgow coma scale)〕，你的初步結論是什么？

3.3你考慮要做哪些輔助檢查?

4　解答

4.1你應該考慮這個病人有顱內占位性病變，特別是硬膜外血腫或硬膜下血腫。

4.2a：簡化的意識程度分類包括5個等級。(1)意識清醒：病人保持清醒的意識；(2)意識混濁：病人的思維混亂；(3)神志不清：病人對搖動和喊叫有反應；(4)輕度昏迷：病人對疼痛有反應；(5)昏迷狀態：病人對任何刺激沒有反應。張某屬于第4級，即輕度昏迷。b：格拉斯哥昏迷量表有三個標準，最高評分15分，最低評分3分。張某得分為8分，提示應該采用腦傷圖對他進行嚴密監測(注：也可以采用其他的昏迷評估量表)。(1)睜眼(4～1分)：張某為2分(疼痛時睜眼)；(2)語言反應(5～1分)：張某為3分(回答含糊不清)；(3)搖動反應(6～1 分)：張某為3分(對疼痛刺激有反應)。

4.3需要做的輔助檢查包括：(1)CT或核磁共振掃描(如果沒有這些設備，可以做X線檢查)；(2)血糖和血酒精濃度檢查；(3)脈搏血氧飽和度；(4)尿藥物篩查。

5　進一步的臨床細節

醫院對張某進行嚴密的觀察。30 min內，護士報告說他發出一些讓人聽不懂的聲音，而且對疼痛刺激的反應很小。體檢發現，左側眼瞳孔收縮。生命體征：脈搏55次/min，血壓160/100 mm Hg，呼吸9次/min。

6　進一步的提問

現在最應該采取什么行動?

7　對進一步提問的解答

很明顯，張某的顱腔內有占位性病變，很可能是急性硬膜外血腫。這需要實行外科引流減壓手術，以挽救他的生命。需要在受傷的頭顱部位鉆孔。如果你沒有足夠的技術和設備做這種手術，則應該立即把病人轉到緊急外科中心。

1　History

ZX,a 62 year old man,was brought into the emergency room by his friends because he was intoxicated from alcohol and had sustained injuries from a fall onto the footpath.Prior to this he had been argumentative and had a fight with two younger men.According to his friends he was a very pleasant and clever public servant but had a history of binge drinking of beer and spirits.Now they were most concerned about him since he had become uncharacteristically confused and unable to walk normally.About an hour previously and soon after his fall he had been conversing with them and seemed well orientated but gradually became irritable,confused and disorientated.

2　Examination

On examination he looked unwell,had superficial injuries and smelt of alcohol.His speech was incoherent as it was slurred and garbled.He had lacerations to the scalp,a bruise of the left side of the head,neck and both arms.

His vital signs were pulse 64/min regular,BP 140/90 mm Hg.Respiration 14/min.It was not possible to perform a mental state examination.He would not respond to verbal commands on request including opening his eyes.He would mumble inappropriate words in response to shouting in his ear.However in response to painful stimuli(digital pressure over the supraorbital ridge) he would open his eyes and withdraw from the pain.

3　Questions

3.1What particular conditions in this man would you be concerned about?

3.2In objective assessment of his conscious state what would be your description of a.the classification according to the 5 conscious levels；b.the Glasgow coma scale(if applicable).

3.3What investigations would you consider?

4　Answers

4.1You should be concerned about an intracranial space occupying lesion such as an extradural haematoma(in particular) or a subdural haematoma.

4.2a.The simplified classification of conscious levels is consciousness(awake),clouded consciousness(confused),stupor(responds to shake and shout),semi comatose(responds to pain) and coma(unresponsive).ZX is level 4-semi comatose.b.The Glasgow coma scale(15 to 3) has three criteria.(1)Eye opening(4 to 1)ZX scores 2(eyes open to pain).(2)Verbal response(5 to 1)ZX scores 3(inappropriate words).(3)Motor response(6 to 1)ZX scores 3(withdraws from painful stimuli).The total Glasgow coma score for ZX is 8/15 which equates to taking care and monitoring closely with a head injury chart′.

Note:Readers may use another and perhaps better coma assessment scale.

4.3Investigations to consider include:(1)imaging-CT or MRI scan(plain X ray if these unavailable).(2)blood sugar and alcohol.(3)pulse oximetry.(4)urine drug screen.

5　Further clinical details

ZX was placed under careful observation.Within 30 minutes the observing nurse reported that he was now making incomprehensible sounds and there was minimal response to painful stimuli.Examination of the eyes revealed a constricted pupil on the left side.His vital signs were pulse 55/min,BP 160/100 mm Hg.Respiration 9/min.

6　Further question

What would be the most appropriate course of action?

7　Answer of further question

ZX obviously has a space occupying mass in his skull,probably an acute extradural haematoma.It demands decompression with surgical drainage as a life saving procedure.This is achieved via a burr hole at the location of the trauma.Immediate referral to an emergency surgical centre is mandatory assuming that you do not have the necessary skills and equipment to perform this procedure.
