RT Journal A1 SAMSON JH T1 RAised intracranial pressure JF American Journal of Diseases of Children JO American Journal of Diseases of Children YR 1979 FD October 1 VO 133 IS 10 SP 1081 OP 1081 DO 10.1001/archpedi.1979.02130100105028 UL http://dx.doi.org/10.1001/archpedi.1979.02130100105028 AB Sir.—The article on increased intracranial pressure by Nugent et al (133:260-262, 1979) in the Journal stated that "rectal temperature was maintained at 35 °C to 36 °C without need for more profound hypothermia." This leads the reader to believe that this range is the optimal body temperature for managing a patient with increased intracranial pressure.I believe it is essential to point out that Rosomoff1 reported the effect of body temperature on CSF pressure. He showed the following relationship between pressure and temperature: 120 mm H2O at 37 °C; 118 mm H2O at 36 °C; 125 mm H2O at 35 °C; 117 mm H2O at 34 °C; 101 mm H2O at 33 °C; 92 mm H2O at 32 °C; and 83 mm H2O at 31 °C. It can be seen that the CSF pressure
