199

The neurosurgery exam should be listed in a standard fashion as follows:

1. Airway

1. Mental status

1. Cranial nerves

1. Strength exam

1. Drift assessment

1. Sensory exam

1. Reflexes

Depending on the patient's specific pathology, these elements of the exam may contain more detail and additional elements may be included. These additional elements include:

1. Rectal exam

1. Language function

=== Airway ===

The status of the patient's airway. The description should be followed by the O2 concentration, flow, or relevant oxygenation parameters.

Options include:

1. Room air (RA)

1. Nasal cannula (NC), E.g. "**6L NC**"

222

1. High flow nasal cannula aka heated high flow nasal cannula. E.g. "**HFNC 70% FiO2, 50L/min**"

223

1. Face tent. E.g. "**Face tent 100% FiO2**"

224

1. BiPAP. E.g. "**BiPAP 40/5**" which means 50% FiO2, 5 PEEP

225

1. Intubated

226

11. Pressure support. E.g. "**PS 40/5**" which means 40% FiO2 and 5 PEEP

227

11. Assist control. E.g. "**AC 40/5**" which means 40% FiO2 and 5 PEEP

228

1. Tracheostomy

229

11. Room air or "trach mask". E.g. "**TM**"

230

11. Ventilated

231

111. Pressure support. E.g. "**Trached PS 40/5**" which means tracheostomy in place, on pressure support ventilation at 40% FiO2 and 5 PEEP

232

111. Assist control. "**Trached AC 40/5**" which means tracheostomy in place, on assist control ventilation at 40% FiO2 and 5 PEEP

233

234

=== Mental status ===

Two components:

1. Eyes

11. Eyes open spontaneously "**EOS**"

240

11. Eyes to voice "**ETV**"

241

11. Eyes to pain "**ETP**"

242

11. Eyes closed "**EC**"

243

1. Orientation. E.g. "**AOx3**"

244

11. Own name. A first name is enough.

245

11. Date. The current year is enough.

246

11. Location. The current city or the setting. E.g. "Pittsburgh" or "hospital" or "emergency department"

247

248

=== Language function ===

249

250

This is an optional exam component. Not every patient will have this included but it should be included on patients at risk for aphasia.

251

Document the presence of word-finding difficulty or "**WFD**".

253

254

* Naming. Test 3 things. "What is this? A pen. What do you do with it? Write. What comes out of the tip? Ink". "**Names 3/3**"

255

* Repetition. Test 2 things. "Repeat after me - 'no ifs ands or buts about it' and 'it's a sunny day in Pittsburgh, Pennsylvania' ". "**Repeats 2/2"**

256

* Complex command, i.e. "take your left thumb and touch your right ear". "**Complex command 1/1**"

257

258

=== Cranial nerves ===

==== ====

==== All patients: ====

263

264

* Extraocular movements intact. "**EOMI**". If there is a EOM palsy, it should be listed. E.g. "**partial L VI palsy**"

265

* Pupils equal, round, and reactive. "**PERRL**". If there is an asymmetry it should be listed. E.g. "**L pupil 3mm reactive, R 5 mm sluggish**". "NR" in this context means "non-reactive"

266

** Document the presence of an afferent pupillary defect (**APD**) if present

267

* Face symmetric. "**FS"**. If there is a facial palsy it should be qualified as central or peripheral

268

** Central facial weakness affects the lower half of the face only. "**right CFW**"

269

** Peripheral facial weakness affects the upper and lower face and should be graded using the House-Brackmann grading scale. "**right HB6**" is read as right House-Brackmann grade 6 peripheral facial weakness

270

* Facial sensation.

271

** Facial sensation intact

272

** Right V1-V3 diminished sensation to light touch or pinprick

273

* Tongue midline. "**TML**". If there tongue deviation is present it should be noted. E.g. "**right CN12 palsy**"

==== ====

==== Intubated patients: ====

278

279

* Cough reflex - present or absent

280

* Gag reflex - present or absent

281

* Corneal reflex - present or absent

282

283

May sometimes be abbreviated as "**c/g/c**".

==== ====

==== Additional cranial nerves are tested on appropriate patients: ====

288

289

* Palate elevates symmetrically. No abbreviation. If there is uvular deviation, note to which side. E.g. "**uvula deviates left**"

290

* Visual acuity graded with bedside Snellen eye chart. "**OD 20/40, OS 20/200**". OD - right eye, OS - left eye, OU - both eyes.

291

** When vision is worse than can be graded on the Snellen chart, it is graded in descending order as follows:

292

*** Finger counting (**FC**) - patient reliably counts fingers in that eye or visual field

293

*** Movement perception (**MP**) - reliably detects movement but cannot count fingers

294

*** Light perception (**LP**) - reliably detects the presence or absence of light but cannot see movement

295

*** No light perception (**NLP**) - no light perception, complete blindness. This is often associated with an afferent pupillary defect (**APD**).

296

* Visual fields assessed with bedside finger counting

297

** Visual fields full (**VFF**). No visual field defect.

298

** Left or right homonymous hemianopia (**HH**).

299

** Quadrantanopia, qualified with superior/inferior and nasal/temporal

300

** Bitemporal hemianopia

301

* Hearing (CN VIII)

302

* Shoulder shrug (CN XI)

303

304

=== Strength exam ===

305

306

Graded on a scale from 0-5:

307

308

* 0 : no movement across a joint, no muscle activity

309

* 1 : no movement across a joint, muscle activates

310

* 2 : movement across joint but not antigravity

311

* 3 : antigravity but not more

312

* 4- : slight strength against resistance

313

* 4 : antigravity strength against resistance

314

* 4+ : significant strength against resistance but not full strength

315

* 5 : full strength

316

317

If a patient is intubated or unable to comply with a detailed strength assessment, strength is graded according to the GCS scale:

318

319

* Flaccid (**flac**)

320

* Extensor posturing "**ext**"

321

* Flexor posturing in upper limb or triple flexion in lower limb "**flex**" or "**TF**"

322

* Withdraw to pain "**wd**"

323

* Localize to pain "**loc**"

324

* Follows commands "**FC**". Usually a reliable thumbs up or toe wiggle.

325

* You may occasionally see "spontaneous and antigravity" or "**spont AG**", which is better than localizing but not as good as following commands.

==== ====

==== Cranial patients ====

330

331

Strength is crudely graded by extremity and listed as a 2x2 square. The upper half of the square denotes the upper extremities and the lower half the lower extremities. Unless otherwise specified, the right half of the square refers to the patient's left hemibody and the left square to the right hemibody.

right arm / left arm

right leg / left leg

3 / 5

5 / 4+ means antigravity in right upper extremity, significant strength against resistance but not full strength in left lower extremity.

338

339

In cranial patients, there is not usually a need to define strength in specific muscle groups.

340

341

342

==== Spine patients ====

343

344

Unless otherwise specified, notation follows the same convention as for cranial patients but each extremity is assessed on the basis of 5 muscle groups.

right arm / left arm

right leg / left leg

The order of upper extremity muscle groups is:

350

351

1. Shoulder abduction

1. Elbow flexion

1. Wrist extension

1. Elbow extension

1. Hand grip

The order of lower extremity muscle groups is:

1. Hip flexion

1. Knee extension

1. Ankle dorsiflexion

362

1. Great toe dorsiflexion

363

1. Ankle plantarflexion

364

365

Strength in each extremity will often be documented with a series of 5 numbers immediately after one another as follows:

44+555 / 34+555

55555 / 55555

This should be read as right arm: 4/5 shoulder abduction, 4+/5 elbow flexion, full strength distally; left arm: 3/5 shoulder abduction, 4+/5 elbow flexion, full strength distally. Full strength in bilateral legs.

371

372

=== Drift assessment ===

373

374

Should be routinely assessed for each arm and described as "**RUE drift**". It is occasionally qualified on the basis of whether the arm drifts down to the bed.

375

376

Drift can be assessed in the legs but is not routinely. This is most relevant for patients at risk of ischemia in the ACA territory such as in the setting of vasospasm.

=== Sensory exam ===

Most often described as sensation intact to light touch in all four extremities or "**SILT x4**". May be further refined if there is loss of sensation in an extremity, a dermatome, or below a dermatomal level. Pinprick, temperature, and proprioception are not routinely tested but may be included in the appropriate clinical context.

=== Reflexes ===

Hoffman, clonus, and Babinski should be routinely assessed. Hyperreflexia should be qualified with the side and location of hyperactive reflexes. E.g. "**right knee extensor hyperreflexia**"

=== Rectal exam ===

Document the presence or absence of:

389

390

* Peripheral anal sensation

391

* Deep anal sensation
