Ampicillin Resistance and Outcome Differences in Acute Antepartum Pyelonephritis

Table 5

Comparison of hospital courses of women with ampicillin-resistant versus ampicillin-sensitive uropathogens in acute antepartum pyelonephritis. Data are reported as 𝑛 (%) or mean±standarddeviation.

	Ampicillin-resistant	Ampicillin-sensitive	𝑃-value
Maximum temperature	38.7^∘C±0.8	38.7^∘C±0.9	0.79
Anemia^1	39 (24)	35 (23)	0.75
Renaldysfunction^2	2 (1)	1 (1)	0.59
Respiratoryinsufficiency^3	15 (9)	13 (8)	0.79
Preterm birth in weeks
<37 estimated gestational age	7 (5)	5 (4)	0.56
<32 estimated gestational age	4 (3)	2 (2)	0.41

¹Anemia was defined as a hematocrit less than 30%.²Renal dysfunction was defined as a creatinine ≥1.2 mg/dL.³Respiratory insufficiency was defined as dyspnea, tachypnea, and hypoxemia with radiological signs of pulmonary infiltrate.
