  • Traumatic Brain Injury (TBI)

    Definition

    Blunt and/or penetrating injury to the head and/or brain due to external force, with temporary or permanent impairment in brain function which may or may not result in underlying structural changes in brain

    Changes in Brain after TBI

    Anatomical changes

    • Intracranial lesions e.g. contusion, cerebral oedema, acute subdural haemorrhage (ASDH), Intraventricular hemorrhage (IVH)
    • Skull fracture
    • Scalp wound
    • Facial wound

    Physiological changes

    • Alteration in mental state e.g. slow thinking, confusion
    • Loss / reduced consciousness
    • Loss of memory (amnesia) of events immediately before and / or after TBI
    • Neurological deficits e.g. change in vision, sensory loss, loss of balance, body weakness

    Classification

    Severity of head injury

    • Mild head injury: GCS 13 – 15
    • Moderate head injury: GCS 9 – 12
    • Severe head injury: GCS 3 – 8
  • Pain as the 5th Vital Sign & Acute Pain Management

    Scales for Pain

    Visual analogue scale (VAS):

    Documentation e.g. VAS 3, VAS – 7

    Modified WHO Analgesic ladder for acute pain management

    Further reading: CPG Pain as the 5th vital sign (3rd edition)
  • R.I.C.E

    RICE treatment for acute musculoskeletal injury aims to relieve pain and swelling and promote healing and flexibility

    • Rest the injured area for 48 hours
    • Ice for 20 minutes at a time; 4 – 8 times a day
    • Compress to help reduce swelling
    • Elevate the injured limb 15 – 25 cm above heart
  • Red Eyes

    History Taking

    Foreign body sensation?

    • Objective: Unable to spontaneously open the eye / keep the eye open — suggests corneal involvement ❗️
    • Subjective: “grittiness” / “scratchy feeling” / “like sand in my eyes” — does not necessarily suggest corneal problem

    Itchy sensation? (seen in conjunctivitis)

    Unilateral or bilateral?

    • Unilateral followed by bilateral: suggests infective conjunctivitis
    • Bilateral: occurs in allergic conjunctivitis
    • Unilateral: occurs in iritis, angle-closure glaucoma

    Discharge?

    • Watery? (suggests viral conjunctivitis / corneal epithelial defects / abrasions)
    • Purulent? (suggests bacterial / chlamydial conjunctivitis)
    • Mucoid? (suggests allergic conjunctivitis)

    Vision affected?

    • Transient blurring due to watery discharge?
    • Persistent significant visual loss? suggests more severe disease e.g. infectious keratitis, iritis, angle-closure glaucoma

    Photophobia // sensitive to bright light? (suggests corneal involvement / iritis) ❗️
    (patient presentation: wearing sunglasses or hat / covering affected eye with hand / keep head down / request for light to be off)

    Recent trauma / eye surgery / contact lens wear? (contact lens wear + painful / discomfort red eye with discharge suggest keratitis)

    Double vision?

    Morning crusting followed by watery discharge (suggests stye / allergic conjunctivitis / viral conjunctivitis)
    **A lot of time patient interpreted morning crusting as ‘pus’ discharge

    ====
    SYSTEMIC REVIEW / FURTHER HISTORY
    Headache, nausea / vomiting (suggests angle-closure glaucoma if eye is painful without discharge) ❗️
    Runny nose (suggests conjunctivitis)

    Allergy / bronchial asthma / eczema? (suggests allergic conjunctivitis)
    Systemic illness e.g. SLE, ankylosing spondylitis

    Physical Examination

    Visual acuity using Snellen chart (reduced visual acuity with previous normal visual acuity suggests more worrisome problems e.g. angle-closure glaucoma, infectious keratitis, iritis ❗️

    Pupils reactive to light? (pupils fixed in mid-dilatation suggests angle-closure glaucoma)

    Corneal opacity — White spot / opacity / foreign body on the cornea? ❗️

    Hypopyon? Hyphema?

    • Hypopyon suggests keratitis / endophthalmitis
    • Hyphema suggests significant blunt / penetrating trauma

    Purulent discharge?

    Pattern of redness

    • Diffuse injection involving palpebral conjunctiva & bulbar conjunctiva: suggests conjunctivitis
    • Ciliary flush (injection more marked at limbus): suggests more serious conditions e.g. angle-closure glaucoma, keratitis, iritis

    Redness: injection (dilated blood vessel) or haemorrhage?

    • Haemorrhage: suggests subconjunctival haemorrhage

    Redness: Diffuse / localised?

    • Localised: suggests foreign body, pterygium, episcleritis

    Fluorescent eye test (if indicated; performed at the end of eye examination)

    • Staining defects (e.g. bacterial keratitis, corneal abrasion)
    • Note: corneal foreign body will not pick up the stain

    Miscellaneous

    Bacterial conjunctivitis VS Bacterial keratitis

    Bacterial conjunctivitis: opaque discharge that persists throughout the day; typically NOT associated with reduction in visual acuity / photophobia / foreign body sensation

    Bacterial keratitis: opaque discharge that persists throughout the day; ±reduction visual acuity, +photophobia, +objective foreign body sensation

  • Ward Round

    Why this patient is still in the ward?

    This is one of the favourite questions asked during ward round, and HOs are also anticipated to answer it during round!

    Some of the popular answers:

    1. To complete IV antibiotics
    2. Awaiting for operation / procedure
    3. For pain management
    4. For blood transfusion
    5. Post major op day _
    6. Patient developed complication from operation / an initially stable disease, thus requiring inpatient management e.g. septic shock, hypovolaemic shock
    7. Logistic issue, no transport available yesterday
    8. “Err … ” (Avoid this. It may indicate that you don’t know about your patient 😂)

    Why the patient is NBM this morning?

    This is one of the questions that you need to ask yourself during AM review, and you would need to anticipate that the same question will be asked again during ward round with MO / specialist later

    Examples:

    • For CECT this morning
    • For OGDS / colonoscopy today
    • For operation under general anaesthesia today
    • The patient developed tachypnoea last night (KIV for intubation today if worsening)
    • The patient had coffee ground vomitus last night

    Miscellaneous

    • One day when you are the only doctor in the ward, and suddenly saw a patient with this breathing pattern. This is not a normal breathing! This is gasping.
      • Gasping is characterized by short, labored breaths that often involve the throat, chest, and abdominal muscles.
      • If the patient is a case where imminent death has been anticipated and not for intubation / CPR, inform MO, KIV to start medications like IVI Fentanyl / IVI Morphine
      • If the patient is a case where death is not anticipated during current admission, it is a medical emergency!
        • Quickly call the MO in charge and give high flow mask oxygen.
        • Check vital signs.
        • Place the patient in the head-tilt chin-lift position to secure the airway while waiting.
        • The patient would need crash intubation for life-saving purpose

    “Mr XXX 50 year old Male
    U/L
    1) Hx of 2 vessel disease
    done stenting under IJN in February 2021
    currently on T warfarin 4 mg OD”

    What further information would you want to find out when seeing the above documentation?

    =====

    It is unusual for IHD to be treated with warfarin, unless he also has other comorbidities or complications e.g. rate controlled atrial fibrillation

    • Check patient’s latest ECG, to look any atrial fibrillation
  • Trigger Finger

    Green Classification of Trigger Finger

    • Grade I: Palm pain and tenderness at A-1 pulley
    • Grade II: Catching of digit
    • Grade III: Locking of digit, passively correctable
    • Grade IV: Fixed, locked digit

    Hence, diagnosis is not simply written as ‘Trigger finger’, but can be written better, e.g. Trigger finger of left ring finger, grade II – grade III

    Treatment (Non-operative)

    • Refer physiotherapy for tendon gliding exercise
  • HO Tips

    Introduce Yourself

    “Who are you? Why are you here?” – asked by a ward consultant

    This happened few days ago when my colleague, a new (senior) HO just started first few days of tagging in a new department. Subsequently the colleague was somehow ‘badly scolded’ for not introducing to the consultant in charge of the ward, and some more he/she is already a senior poster.

    Moral of the story:
    When you are new to any ward / any department, please put initiative to introduce yourself, especially to e.g. Staff Nurse, Ward Sister, MOs, Specialist, and Consultant.

    They might or might not want to know exactly who you are. But your presence has to be acknowledged by them.

    “If somebody who you don’t know before suddenly appears sitting in your house without permission, what would you feel?”

    ASK

    • Ask whenever you are not sure
    • Ask the right person (for certain things you may ask your HO colleagues, while others you should ask the MO / specialist)
    • Ask before complications had happened to the patients / to yourself

    Unlimited Calls

    Buy mobile plan with Unlimited Call (+++Internet data). You might be calling a lot to refer cases or to update cases to MOs of the same/other departments.
    Some MOs prefer us to call using our own phone, so that they can easily contact us regarding patient’s update

    Examples of Poor Attitude (that should be avoided)

    • Consistently coming late
    • Consistently taking MC / EL without valid reason and/or without informing other colleagues
    • Back-stabbing others
    • Being dishonest to colleagues / superior / patients
  • Blood Transfusion

    What House Officer Needs to Take Note?

    GSH

    GSH is valid for 48 hours most of the time. Different blood banks might have different policy on GSH and GXM.

    When requesting for blood / blood products

    Urgency

    ☀️ Need to be clear about the urgency: Not every blood transfusion is urgent, ‘urgent’ means blood must be available in less than 2 hours & the blood cannot be fully crossmatched. Otherwise, ‘non-urgent’ means can wait for 2 hours or more for blood to be fully crossmatched at blood bank.
    ☀️ Why urgent? Is your patient having active / massive bleeding?
    ☀️ Clarify the urgency with your MO if you are not sure.

    Prior to transfusion

    • CHECK the relevant checklist/transfusion request forms (GSH form) / blood bag / case notes/patient to confirm the identity. Check at bedside (in front of patient), by 2 staff (a doctor & a nurse)

    During Transfusion

    Look for signs / symptoms of transfusion reaction, which usually occur during first 30 minutes of transfusion

    If 2 pints packed cells are being transfused, IV Frusemide (e.g. 20 mg) stat can be considered in between transfusion, to prevent fluid overload (confirm with MO first)

    Post Transfusion

    Repeat FBC 6H post transfusion

    Near Miss & Transfusion Error

    Examples of transfusion error

    • Transfusion of ABO compatible blood but to a wrong patient
    • Transfusion of incompatible blood to a patient
