title: Penile intracorporeal infusion--possible access to the systemic circulation. Pressure flow studies in dogs and humans.
abstract: OBJECTIVE
  To assess penile intracorporeal infusion as a simple alternative method of intravenous access during the initial phase of fluid resuscitation in male patients.
  
  
  METHODS
  Laboratory pressure flow studies in dogs and in humans.
  
  
  METHODS
  5 male mongrel dogs, and 10 male patients who were being investigated for psychogenic impotence (n = 5) or organic impotence (n = 5).
  
  
  METHODS
  Dogs- two 19G needles were inserted into the canine corpora cavernosa, one for fluid infusion, and the other for cavernosal pressure monitoring. Ringer's lactate solution was infused into the corpora cavernosa, through an infusion pump. The dogs were then bled until systolic blood pressure reached 60 mmHg, and resuscitated by transfusion of autologous blood into the corpora cavernosa. HUMANS: Ringer's lactate solution was infused into a corpus cavernosum through a 19G scalp vein needle. Pressure monitoring was done through another 19 G needle.
  
  
  METHODS
  Fluid flow rates and in humans time taken to insert an intracorporeal needle.
  
  
  RESULTS
  Mean (SD) infusion rate through the canine corpora was 110 (22) ml/minute for Ringer's lactate solution and 109 (18) ml/minute for autologous blood. Mean infusion rate into the human corpora was 89.7 (12) ml/minute in the psychogenic impotent patients, and 88.2 (9) ml/minute in the organic impotent patients. Mean time taken to insert the needle was 15 (7) sec.
  
  
  CONCLUSIONS
  An intracorporeal infusion line can be established in a short period of time and adequate quantities of fluids can be infused through the human and canine corpora cavernosa.
