Abstract Purpose: The present study investigated whether first trimester mean arterial blood pressure (MAP) differed among pregnancies with placenta accreta and healthy pregnancies.Methods: We recruited 176 pregnant females totally from 1 January 2016 to 30 September 2018 in this study, as follows: 65 cases of placenta accreta and 111 cases of BMI and age matched, healthy pregnant controls. First trimester mean arterial blood pressure (MAP) were acquired from laboratory data files. Multiple logistic regression analysis were used to study analyzed the probable risk predictor of placenta accreta. Results: The performance of MAP was lower in healthy pregnancies. The MAP of the placenta accreta group was significantly higher than that of the cont rol group (p=0.001<0.05). Our results also showed that MAP was significantly positively associated with placenta accreta after adjusting for age, BMI, fertilization type, gestational week at time of blood pressure measurement, and previous cesarean section history (odds ratio [β]: 1.11; 95% confidence interval [CI]: 1.04–1.69; p=0.0013<0.05). In addition, smoking during pregnancy (β: 7.57; 95% CI: 1.41–40.72; p=0.018<0.05) and previous cesarean section history (β: 2.57; 95% CI: 1.19–5.54; p=0.016<0.05) were significantly positively associated with placenta accreta.Conclusions: Increased first trimester MAP was significantly positively associated with placenta accreta, suggesting the potential role of MAP in identifying high-risk pregnancies for placenta accreta. Smoking during pregnancy and previous cesarean section history may be risk factors for placenta accreta.

Abstract Objective The present study investigated whether first trimester mean arterial blood pressure (MAP) differed among pregnancies with placenta accreta and healthy pregnancies. Methods We recruited 152 pregnant females from 1 January 2016 to 30 January 2020 in the Affiliated Hospital of Jining Medical University in this study, including 41 cases of placenta accreta pregnancies and 111 cases of BMI- and age-matched healthy pregnant controls. First trimester MAPs were acquired from laboratory data files of the Affiliated Hospital of Jining Medical University. Multiple logistic regression analysis was used to analyze the probable risk predictor of placenta accreta. Results The performance of MAP was lower in healthy pregnancies. The MAP of the placenta accreta group was significantly higher than that of the control group (p = 0.001 < 0.05). Our results also showed that MAP was significantly positively associated with placenta accreta after adjusting for age, BMI, fertilization type, gestational week at time of blood pressure measurement, and previous cesarean section history (odds ratio [OR]: 1.11; 95% confidence interval [CI]: 1.04–1.69; p = 0.0013 < 0.05). In addition, smoking during pregnancy (OR: 7.57; 95% CI: 1.41–40.72; p = 0.018 < 0.05) and previous cesarean section history (OR: 2.57; 95% CI: 1.19–5.54; p = 0.016 < 0.05) were significantly positively associated with placenta accreta. Conclusions Increased first trimester MAP was significantly positively associated with placenta accreta, suggesting the potential role of MAP in identifying high-risk pregnancies for placenta accreta. Smoking during pregnancy and previous cesarean section history may be risk factors for placenta accreta.

Object. It is taken for granted that patients with hypertension are at greater risk for intracerebral hemorrhage during neurosurgical procedures than patients with normal blood pressure. The anesthesiologist, therefore, maintains mean arterial blood pressure (MABP) near the lower end of the autoregulation curve, which in patients with preexisting hypertension can be as high as 110 to 130 mm Hg. Whether patients with long-standing hypertension experience more hemorrhage than normotensive patients after brain surgery if their blood pressure is maintained at the presurgical hypertensive level is currently unknown. The authors tested this hypothesis experimentally in a rodent model.Methods. Hemorrhage and edema in the brain after needle biopsy was measured in vivo by using three-dimensional magnetic resonance (MR) microscopy in the following groups: WKY rats, acutely hypertensive WKY rats, spontaneously hypertensive rats (SHR strain), and SHR rats treated with either sodium nitroprusside or nicardipine. Group differences were compared using Tukey's studentized range test followed by individual pairwise comparisons of groups and adjusted for multiple comparisons.There were no differences in PaCO2, pH, and body temperature among the groups. The findings in this study indicated that only acutely hypertensive WKY rats had larger volumes of hemorrhage. Chronically hypertensive SHR rats with MABPs of 130 mm Hg did not have larger hemorrhages than normotensive rats. There were no differences in edema volumes among groups.Conclusions. The brains of SHR rats with elevated systemic MABPs are probably protected against excessive hemorrhage during surgery because of greater resistance in the larger cerebral arteries and, thus, reduced cerebral intravascular pressures.
