title: Blood parameters are little affected by time of sampling after the application of ketamine in black howler monkeys (Alouatta pigra).
abstract: BACKGROUND
  Ketamine hydrochloride is an anesthetic commonly utilized to obtain biological samples in various non-human primates. Its application alters individual hematologic and biochemical values. The aim of this study was to analyze its effect on blood parameters of Alouatta pigra.
  
  
  METHODS
  We collected blood samples at 10 and 40 minutes after the application of ketamine in 12 adult female A. pigra living in free-ranging conditions.
  
  
  RESULTS
  The analysis showed that 40 minutes after application of ketamine, the number of platelets, lymphocytes and concentration of phosphorus decreased; however, creatinine, cholesterol, triglycerides, and potassium values increased.
  
  
  CONCLUSIONS
  Our results suggest that ketamine appears to have little effect on the hematology and blood biochemistry of Alouatta pigra females with respect to those reported for other non-human primates. It is also important to consider the elapsed time after their application when taking blood samples for proper interpretation of the hemogram of Alouatta pigra females.
