oA 2-month-old girl arrives at the Emergency Department in cardiac arrest. Other providers promptly begin ventilation and perform chest compression. You need to establish vascular access to administer fluids and medications

I.S.

MD

oWhat is the optimal site for immediate vascular access for this infant?

o If resuscitative efforts are successful, what is the optimal site for vascular access during the post resuscitation period?

I.S.

MD

Objectives

o Prioritize sites of vascular access for different clinical circumstances

o Describe the risks and benefits of peripheral venous, central venous, and intraosseous vascular access

o Describe the IO access technique

I.S.

MD

Selection of site and priorities of vascular access 1

For CPR and treatment of decompensated shock the one that is

o most readily accessibleo not require interruption

I.S.

MD

Selection of site and priorities of vascular access 2

oCompensated shock… large bore peripheral IV catheter

oPost resuscitation phase… central venous catheter

o Intracardiac administration of drugs during closed chest compression

oArterial cannulation

I.S.

MD

Priorities of Vascular Access

oDuring pediatric CPR or treatment of decompensated shock.. IO access

oOne practical approach: IO or peripheral or central access simultaneously

oDuring attempted resuscitation.. Transtracheal …LEAN

I.S.

MD

Intraosseous Access

o Provides access to a noncollapsible marrow venous plexus which serves as a rapid , safe and reliable route of administration

o Often can be achieved in 30-60 seconds by using a rigid needle(specially designed or Jamshidi-type)

I.S.

MD

Intraosseous Access

o A rapid, safe, & effective route for the administration of medications & fluids, & may be used for obtaining an initial blood sample for type & crossmatch & for chemical & blood gas analysis even during resuscitation (Class IIa; LOE 3).

o Acid-base analysis is inaccurate after sodium bicarbonate administration via the IO cannula.

I.S.

MD

Intraosseous Access

o Epinephrine, adenosine, fluids, blood products, & catecholamines can safely be administered.

o Onset of action & drug levels achieved are comparable to venous administration.

o Use manual pressure or an infusion pump to administer viscous drugs or rapid fluid boluses, & follow each medication with a saline flush to promote entry into the central circulation.

Complications

o Complications reported in fewer than 1%o Fracture of Tibiao Lower extremity compartment syndrome o Osteomyelitiso Extravasation of Drugs

I.S.

MD

Central V/S Peripheral Venous Access

o More secure long-term accesso Not higher drug levels or a substantially

more rapid responseo Administration of drugs could injure

tissues(vasopressors ,calcium ,sodium bicarbonate)

I.S.

MD

Complications of central venous cannulation

o Local and systemic infection,venous or arterial bleeding, arterial cannulation, Thrombosis,plebitis, pulmonary thromboembolism,hydro pneumo hemo chylo thorax, cardiac tamponade, arrhythmias, air embolism, catheter fragment embolism

I.S.

MD

Peripheral Venous Access Devices

o Over-the-needle catheterso Catheter-over-wire deviceso Catheter-through-introducing sheath

deviceso Butterfly needles

oThe vessel is elevated with a hemostat & occluded with gentle traction from a distal tie. oThe needle is inserted & the sheath is advanced into the vessel. oThe vessel should not be tied off with this technique.

Summary points

oIntravascular or intraosseous access is the preferred route for medication and drug delivery in cardiopulmonary emergencies.

I.S.

MD

2

o Immediate intraosseous access is recommended in cases of decompensated shock and cardiopulmonary arrest, particularly if the provider lacks experience in pediatric central venous access techniques

I.S.

MD

3

oCentral venous catheterization can be used in children in emergencies. But it requires significant expertise. Many complications and delays may occur in expert hands
