Background

Although peripartum intensive care unit admission indications are well-reported, clinical and laboratory details rarely are. We described admission indications and categorized laboratory values and vital signs according to admission diagnosis.

Methods

Retrospective Institutional Review Board approved study. We identified intensive care unit admission diagnosis, laboratory values and vital signs from patient charts. Groups were compared according to admission diagnoses. Data were analyzed using descriptive statistics.

Results

We included 91 general intensive care unit admissions among 56,865 deliveries (2011-2015) with complete data. The most common admission diagnosis was postpartum hemorrhage followed by hypertensive diseases of pregnancy and respiratory complications. Women with postpartum hemorrhage had lower mean (standard deviation) platelet counts (120.2 (45.8) vs. 181.2 (109.9), p=0.003) and temperatures (35.7 (1.1) vs. 36.5 (1.2), p=0.002). Women with hypertensive diseases of pregnancy had higher mean (standard deviation) blood pressures (systolic 150.4 (29.1) vs. 127.4 (21.0), p=0.013, diastolic 100.3 (18.7) vs. 76.1 (16.1), p=0.001), creatinine (1.1 (0.6) vs. 0.8 (0.3), p=0.003), urea (14.6 (7.7) vs. 10.5 (4.7), p=0.005) and liver enzymes, including aspartate transaminase (258.4 (297.0) vs. 41.4 (42.9), p=0.000), alanine transaminase (184.4 (199.2) vs. 35.1 (75.9), p=0.000), and alkaline phosphatase (166.6 (112.6) vs. 96.0 (60.0), p=0.006). Women with respiratory complications had lower mean (standard deviation) oxygen saturations (93.7 (6.1) vs. 98.0 (2.6), p=0.000), and higher mean (standard deviation) temperatures (37.1 (0.8) vs. 36.0 (1.2), p=0.001).

Conclusions

We report differences in laboratory values and vital signs, according to intensive care unit admission diagnosis. Recognizing these differences might help individualize patient assessment and care.
