Effects of preventive antibiotics on neutrophil phagocytosis as measured by the nitroblue tetrazolium dye test.
White blood cell counts and nitroblue tetrazolium dye tests were performed in three groups of dogs before and after the injection of Escherichia coli using colistimethate sodium and cephalothin sodium in the second and third groups, respectively, prior to the induction of sepsis. The response was a diminished white blood count and increased nitroblue tetrazolium dye test percentage in all groups. When antibiotic administration was performed prior to the induction of sepsis, the increase in the nitroblue tetrazolium reduction dye test was much more evident despite the overwhelming dose of bacteria given, suggesting that antibiotics given preoperatively will prevent the toxic effects of bacteria on the neutrophil and will enhance the phagocytic activity of the neutrophil.

The problems of abdominal operations in elderly patients.
In a series of 152 patients aged 65 years or older who underwent abdominal operations between January 1 and December 31, 1971, the total mortality was 17 percent. Pulmonary pathologic conditions were responsible for the majority of the deaths. Use of IPPB did not significantly influence the postoperative course. This study suggests that meticulous preoperative preparation of patients; deliberate, clean, and efficient surgical techniques; and intensive postoperative care are of utmost importance in surgical treatment of the elderly.
