Excerpt: ...hand. Extra tubing must be put on the blood pressure instrument. A sudden drop in the pressure picture may mean a large hemorrhage. The gradual return of the pressure picture means that the vasomotor mechanism has acted to keep up the pulse pressure. Should the diastolic pressure continually fall, it may mean that the hemorrhage is still taking place (Wiggers). Blood Pressure in Obstetrics One might affirm almost without fear of contradiction that the constant determination of blood pressure during pregnancy is more important than the examination of the urine. Within recent years a number of observers having access to a large material, have given the results of their findings. There is a striking unanimity of opinion, although now and then a difference in minor details. The blood pressure should be taken frequently during pregnancy. The usual and highly essential precautions in taking pressure in general apply most particularly in these cases. Towards the end of pregnancy the pressure should if possible be taken daily and oftener if necessary. Pressure in women is usually below 120 mm. Many patients have a temporary rise in blood pressure during pregnancy, due oftenest to constipation, without developing 153 other symptoms. This is common to all conditions and has no significance. Some think that an abnormally low pressure, that is, a systolic below 90 mm., suggests that the patient is likely to react unduly to the strain of labor. This is denied by others. Among 1000 cases (Irving) the pressure was below 90 in only one case. A gradually rising pressure precedes albuminuria, as a rule. If there is albumin without change in pressure the albumin may usually be disregarded. Some think that a pressure over 130 mm. systolic should be carefully watched. The danger limit is set by some at 150 mm. If the blood pressure from the very first is high, it may mean only that that was the patient's normal pressure. This calls for increased watchfulness.
