    Does
    Bacteremia Occur During High Pressure Lavage of
    Contaminated Wounds.

    Clin
    Orthop 347: 117-121. 1998

         

    This study on 20 dogs investigates the risk of
    bacteremia secondary to high pressure lavage of
    contaminated wounds.

       

    The
    dogs were divided randomly into 4 groups.
    In groups A and B, the wound was contaminated
    with 1.4  x
    10 9 staphylococcus
    aureus
    and were followed 75 minutes later with
    high pressure lavage or bulb syringe irrigation.
    Groups C and D underwent the same treatment but
    without contamination.

       

    No
    detectable bacteremia occurred in the contaminated
    wounds.  However
    bacteremia was detected in 18 of 20 control dogs.  High pressure lavage reduced bacterial levels by 70% and bulb
    irrigation by 44%.

      

    It
    is concluded that high pressure lavage reduced wound
    bacteria more consistently than bulb irrigation did.

    Phantom
    Sensations Generated by Thalamic Microstimulation.

    Nature 391: 386-387, 1998.

       

    Thalamic neuronal responses and stimulation
    induced sensations were analysed in patients with
    postamputation pain to gain better understanding of
    the thalamic mechanisms underlying phantom sensations.

        

    Thalamic
    mapping demonstrated an unusually large thalamic stump
    representation.

        

    More
    research is needed to further define the electrode
    activity in the thalamus and to assess potential
    pharmacologic or stereotactic interventions.

    Prospective
    Evaluation of Early Missed Injuries and the Role of
    Tertiary Trauma Survey.
      
    Injury
    Infect Crit Care 44: 1000-1007.


         

    Many trauma
    patients have missed injuries even after primary and
    secondary trauma survey. 
    These assessments cannot be regarded as
    definitive. A
    tertiary trauma survey is needed to reduce the rate of
    missed diagnosis.

          

    The
    study identifies factors responsible for missed
    diagnosis.

    The First Randomized Trial of Human Polymerized
    Haemoglobin as a blood substitute in Acute Trauma and
    Emergent Surgery


    J Am Coll Surg  187:
    113-122, 19998

       

    Polymerized
    haemoglobin appears to be safe and clinically useful
    blood substitute in patients with acute blood loss.
    Although the use of Polymerized Haemoglobin is
    associated with reduciton in Red Blood Cell
    Haemoglobin, it preserves total haemoglobin and
    reduces requirement for allogenic blood.

       

    Advantages
    : Safe and Effective Blood Substitute 
    because of :-

       

    1.                
    Immediate availability

    2.                
    Compatibility with all blood types

    3.                
    Freedom from transfusion reactions

    4.                
    Freedom from transmission of hepatitis, AIDS
    and other blood borne diseases

    Biologically
    inert-hence no immune reactions and no potentiation of
    infection.
