“The Medic’s Oath”

Here is the poem I want to rewrite in a complete new voice, perspective, you can even change the POV. 
Poem: Title: Saline Lock
This week, in training— as a combat medic     needles glinting      under fluorescent light      
My battle buddies and I      
practiced     on mannequins first     their rubber skin     
yielding easily    obediently     But then      
it was time     for each other     flesh to flesh     
My turn first     an 18-gauge needle     
poised like a spear     flush syringe     ready to follow     
Steps repeated     in my head     
like a prayer: constricting band     sterilize     pull skin distal     puncture     attach saline lock     flush     and wrap     
I breathed steady     
focused     saline lock secured     Then my turn     
to have my     Medial Cubital Vein     pierced    
My battles’ hands     trembling like    
leaves in a storm     the needle quivering     
He tried to hide      but I felt     his anxiety     
vibrating through the air     
Trust wavered     my vein suddenly    
detached     skin a fortress      His eyes    
pools of worry     mirrored my own     I offered my arm     
steady like a true soldier     yet inside  
electrical currents clashed     waves of doubt     
and hope colliding     He began     
each motion heavy     with hesitation    
each breath a mountain  salty sweat sabotaging his view     
San Antonio’s humidity not helping      The needle approached     
a slow invasion     Time stretched    thin     
and fragile     seconds like hours     Then, the puncture     
sharp     acute but brief     Saline flushed     a clear surrender     
Relief     and sigh     washed over both of us     the lock a bridge     
between fear     and courage     anxiety     and trust      
Under harsh light     and hot humid temperatures     
a step closer     toward our Hippocratic Oath     of saving lives.
