The authors have studied several blochemical parameters in maternal and cord blood from 18 normal deliveries ocurred in Cerro de Pasco, at an altitude of 14000 ft.; as control 16 cases attended at the Maternity Hospital in Lima (445 ft.9 were studied. Newborn weights were similar: 3205 ± 343 g in C. P. and 3086 ± 495 g in Lima; Apgar score was also similar 8.4 and 8.2  respectively. In cord blood mean values in C. P. were: Hematocril 52.5 % ± 6.5 %; pottassium 6.0 ± 0.9, sodium 146 ± 9.3, chloride 110 ± 7.7 m.Eq ./L creatinine 1.14 ± 0 .3, glycemia 67 ± 19 and urea 32.2 ± 12.9 mg.%. Same determinations in Lima were: Hematocrit 48.8 % ± 4.5, similar to  C. P. (p > 0.05]; pottassium 5.0 ± 0.4, sodium 136 ± 2.2 and chloride 103 ± 2.6 m.Eq ./L; the electrolite valves were lower in Lima with p values of > 0.006, < 0.02 and < 0.001 respectively. Creatinine was 0.84 ± 0.3 mg.% l...
