The Relationship

Objective The objective of this study was to test the association between fetal intravenous anesthesia and the change in middle cerebral artery peak systolic velocity (MCA-PSV) in patients undergoing intrauterine transfusion (IUT) for suspected fetal anemia. Study Design We retrospectively examined data from all patients who underwent IUT via umbilical cord route from 2007 to 2016. We calculated the change of the MCA-PSV multiple of median (MoM) as the difference in MCA-PSV MoM between the pre- and immediate postoperative measurements for the first IUT. The change in MCA-PSV MoM was compared between those who did and did not receive fetal anesthesia using Kruskal–Wallis' testing. Results Of 62 patients, 37 (59.7%) received intravenous fetal anesthesia and 25 (40.3%) did not. The change in MCA-PSV MoM did not differ between those who did and did not receive fetal anesthesia (median: 0.57 [interquartile range, IQR: +0.42 to +0.76] vs. median 0.57 [IQR: +0.40 to +0.81], p = 1.000). The relationship remained insignificant when stratifying by gestational age, length of procedure, initial MCA-PSV, and when excluding hydropic fetuses. Conclusion Among women undergoing IUT, there was no evidence that the use of fetal anesthesia was associated with a change in the pre- versus postoperative change in MCA-PSV MoM.

This observational type of descriptive study was carried out in the Department of Radiology and Imaging, BIRDEM selecting 70 Bangladeshi pregnant babies with the aim to find out the normogram of foetal middle cerebral artery Doppler flow velocity indices and correlation between Doppler flow velocity indices [Resistance Index (RI), Pulsatility Index (PI), Systolic/Diastolic ratio (S/D) & Peak Systolic Velocity (PSV)] of foetal middle cerebral artery and gestational age in normal pregnancies of 20 to 40 weeks. It was observed that RI, PI and S/D were decreased with the advance of gestational age but PSV was increases with the advance of gestational age. Statistical analyses showed there were significant difference between mean PSV, RI and PI before and after 25 weeks of gestation. No significant difference was found between mean S/D before and after 25 weeks of gestation. It was observed from Correlation analysis between Doppler indices with independent gestational age that all the Doppler indices of foetal middle cerebra artery was positively correlated with the whole gestation period. The statistical analysis showed only PSV and RI were significantly correlated with the gestational age. Simple regression analysis between dependent Doppler index with independent gestational age before and after 25 weeks revealed that all the Doppler indices had positive relationship with the corresponding gestational age but relationship between PSV and PI (before 25 weeks) with their corresponding gestational ages were only statistically significant.DOI: http://dx.doi.org/10.3329/birdem.v2i2.12306 Birdem Med J 2012; 2(2) 77-80
