INTRODUCTION
What constitutes a surgical emergency-?
A patient who requires :
an immediate,urgent,early surgical operative intervention [ of any
extent] to either save his life OR to prevent a
disability

What constitutes Mass surgical
causalities Or emergencies ?

INTRODUCTION
Any time /situation/occurrence when there are ‘more Patients than Rescuers and immediately available resources’
A major incident An event whose impact cannot be handled within
routine service and arrangements. It requires the implementation of special procedures by one, or more, of the Emergency Services.
![Page 9: MANAGEMENT OF MASS SURGICAL EMERGENCIES](https://reader036.vdocuments.site/reader036/viewer/2022062314/56814882550346895db5930d/html5/thumbnails/9.jpg)

INTRODUCTION
levels /spectrum of major incident
• LEVEL I INCIDENTS multi-vehicle road traffic accidents, tens of casualties
• LEVEL II - Much larger scale events affecting potentially hundreds, rather than tens, of people,
possibly also involving the closure or evacuation of a major facility or persistent disruption over many days. This level of incident will require a collective response by several, or many, Trusts.
• LEVEL III INCIDENTS - Events of potentially
catastrophic proportions that severely disrup thealth and social care services and other functions (power, water, etc)and that exceed even collective capability.

Answ. A Rationale,systematic,well structured,
coordinated and well organized approach in patient care.
The ‘theme’ in development of ‘principles of management’ of mass surgical emergencies and the ‘Trauma care system’
i.e. ‘a system approach in patient care’

2-PRINCIPLES OF MANAGEMENT Differences from
ordinary trauma management-- ?
One casualty vs tens reporting simultaneously

In ordinarily situations there are: tens of service men to attend a single causality
In mass casualty incident there are: Tens of casualties to be attended by
only a few service men

PRINCIPLES OF MANAGEMENT
TRIMODAL PATTERN OF DEATH:
• Immediate death - first peak within seconds of the injury, massive head injury, heart injury, or aortic injury. cannot be prevented.
• later death - second peak hemorrhage or direct organ compromise, deaths begins an hour or two after the injury- “golden
hour. subdural and epidural hematomas, hemo-pneumothorax, organ rupture, or blood loss. These deaths are often preventable • Delayed death –third peak due to complications and organ failure. due to sepsis or multi-organ failure. Prompt treatment of shock and hypoxemia during the “golden hour” can reduce these
deaths

33
PRINCIPLES OF MANAGEMENT Some Considerations
• Mass casualties are characterized by such numbers, severity,
and diversity of injuries that can overwhelm the ability of local
medical resources to deliver comprehensive and definitive medical care to all victims. • Surgeons play the pivot role BUT every one in the system has a unique contribution
• The training and skills of doctors is important
• Resources and infrastructure of trauma centers and trauma
systems should be suited for the logistical demands
• Rapid decision making required by large casualty burdens

37
PRINCIPLES OF MANAGEMENT
THE BASIC PRINCIPLES
Actual treatment is done on the same principles as in usual victims of trauma –but with greater speed and on priorities
1- Triage and early transportation 2- Primary survey & resuscitation identification
& treatment of immediate life threat] 3- Secondary survey [ detailed examination, assessment and definitive subsequent Damage control surgical treatment and]
4- Continued care 5- Rehabilitation/follow up
![Page 38: MANAGEMENT OF MASS SURGICAL EMERGENCIES](https://reader036.vdocuments.site/reader036/viewer/2022062314/56814882550346895db5930d/html5/thumbnails/38.jpg)
38
PRINCIPLES OF MANAGEMENT
1-Triage
Selection/prioritization of cases on the ‘merit of the severity of their conditions’ to establish priorities for care -- based on available resources
See who needs attention first Based on quick Primary survey
![Page 39: MANAGEMENT OF MASS SURGICAL EMERGENCIES](https://reader036.vdocuments.site/reader036/viewer/2022062314/56814882550346895db5930d/html5/thumbnails/39.jpg)
39
PRINCIPLES OF MANAGEMENT
1-Triage • Proirity-1 / Red –- highest priority need immediate care (usually circulatory or respiratory]
• Proirity-2 / Yellow -second highest priority able to wait longer before transport (45 minutes)
• Proirity-3 / Green- walking - able to wait several hours
• Proirity-4 / White- Expectant-where out come is gloomy –
severe head injury, spinal cord injury• Proirity-5/ Black – Dead

44
PRINCIPLES OF MANAGEMENT
1-Triage –points to remember• It is primarily based on quick and orderly primary
survey• It’s a dynamic process –i.e sorting & resorting May be repeated at different levels of care
Because • A bulk sorted at the scene of accident and
moved to Tauma ctr when RE_SORTED and re examined –may differ and change in poirities
• Sorting station at trauma ctr may be first triage site
• Actual condition of the victim may change with time and during transportation
• Initial assessment may be false –under/over

PRINCIPLES OF MANAGEMENT
1-Triage –points to remember Primarily concentrate on selection of severely injured
who has a good chance of survival
if treated well in time OR who will die if not treated in time

PRINCIPLES OF MANAGEMENT
2-Primary survey & Resuscitation ABCDE of Trauma
The ‘primary’ survey, should identify such life-threatening injuries such as:
• airway obstruction• chest injuries with breathing difficulties• severe external or internal haemorrhage• abdominal injuries.

PRINCIPLES OF MANAGEMENT
Sequence of Resuscitation -ABCDE- of trauma care
AirwayAssess the airway. Can patient talk and breathe freely? If
obstructed, the steps to beconsidered are:• chin lift/jaw thrust (tongue is attached to the jaw)• suction (if available)• Insert airway/nasopharyngeal airway• Intubation. NB keep the neck immobilised in neutral
position.BreathingBreathing is assessed as airway patency and breathing
adequacy are re-checked. Ifinadequate, the steps to be considered are:
• Decompression and drainage of tension pneumothorax/haemothorax
• Closure of open chest injury• Artificial ventilation.• Give oxygen if available.

PRINCIPLES OF MANAGEMENT
Sequence of Resuscitation -ABCDE- of trauma care
Circulation• Assess circulation, as oxygen supply, airway patency
and breathing adequacy are re-checked. If inadequate, the steps to be considered are:
• Sstop external haemorrhage• Establish 2 large-bore IV lines (14 or 16 G) if possible• Administer fluid if available. Disability• Rapid neurological assessment (is patient awake,
vocally responsive to pain or unconscious). There is no time to do the Glasgow Coma Scale so a

PRINCIPLES OF MANAGEMENT
2-Primary survey & Resuscitation Summary
• Check and establish airways – chin lift, jaw thrust, intubate.
e.g. Oropharyngeal /neck/chest injuries• Check and restore breathing –
Manual,mechanical,intubate. e.g. Haemopneumothorax• Check &R circulatory shock – stop visible bleeding, i/v
line balanced salt solution e.g. major vascular injuries• Check for neurological deficit.• Stabilize neck –manually/with collar supports

PRINCIPLES OF MANAGEMENT
2-Primary survey & Resuscitation
Remember that:• Primary survey and immediate
therapeutic measure go side by side• A life saving procedure done by one
person /team may be supplemented by examination by other person/team and may draw attention to an associated serious condition [ex-4]
• Try to minimize the chance of missing any important feature

Conclusion
The management of mass casualties is only one of many critical functions
involved in the overall response to a disaster.
Education training and rehearsal are especially important • Disaster planning and Integration of local, regional, and
national levels .• Hospital Emergency Incident Command Systems (HEICS).• Communications and security.• Media relations.• Protection of health care delivery personnel and facilities.• Detection and decontamination of biological, chemical, and
radiation exposure.• Triage principles and implementation.• Logistics of medical evaluation, stabilization, disposition,
and treatment of victims.• Record-keeping and postdisaster debriefing, critique, and
reporting.• Critical incident stress management (CISM).• Published research and experience in disaster
management.
