Maternal hemoglobin level and its relation to fetal distress, mode of delivery, and short-term neonatal outcome: a retrospective cohort study.

Aim: We aimed to investigate if the risk of fetal distress during term labor is related to the intrapartum maternal hemoglobin (Hb) level. Second, we investigated the relation between mode of delivery, reason for instrumental delivery and short-term neonatal outcome and maternal Hb. Third, we aimed to identify factors influencing intrapartum maternal Hb level.Methods: A retrospective cohort study was performed in a tertiary hospital in The Netherlands, including data from women who gave birth between 2009 and 2016. To determine whether the likelihood of fetal distress to occur was dependent on intrapartum Hb, multivariate regression models were run with intrapartum Hb as the main independent variable of interest. Hb was used as a continuous value. We repeated this procedure for the likelihood of instrumental vaginal delivery (IVD), cesarean section (CS), 5-min Apgar score < 7, and umbilical cord arterial pH ≤ 7.05 to occur. Also, we identified factors influencing intrapartum Hb level using linear regression analysis.Results: Data of 9144 patients were analyzed. Intrapartum Hb did not contribute to the prediction of the likelihood of fetal distress, IVD for nonprogressive labor, CS for fetal condition, 5-min Apgar score < 7, and pHa ≤ 7.05. However, there was a unique statistically significant contribution of Hb to the prediction of the likelihood of IVD for any reason and IVD for fetal distress and CS for any reason and CS for nonprogressive labor. IVD for fetal distress was related to a higher intrapartum Hb level, whereas CS for nonprogressive labor was related to a lower intrapartum Hb level. Intrapartum Hb level was influenced by maternal age, ethnicity, parity, fetal sex, and birth weight.Conclusions: The risk of fetal distress and adverse neonatal outcome is not related to intrapartum Hb levels. However, our data suggest that mode of delivery is dependent on intrapartum Hb, as shown in a large tertiary population. We recommend further investigating this relation in a large prospective study.

A Virtual Reality Video to Improve Information Provision and Reduce Anxiety Before Cesarean Delivery: Randomized Controlled Trial.

BACKGROUND: Anxiety levels before cesarean delivery (CD) can lead to a negative birth experience, which may influence several aspects of the woman's life in the long term. Improving preoperative information may lower preoperative anxiety and lead to a more positive birth experience. OBJECTIVE: This study aimed to determine whether a virtual reality (VR) video in addition to standard preoperative information decreases anxiety levels before a planned CD. METHODS: Women scheduled to undergo term elective CD were recruited from the outpatient clinic. They were randomized and stratified based on history of emergency CD (yes or no). All participants received standard preoperative information (folder leaflets and counseling by the obstetrician); the VR group additionally watched the VR video showing all aspects of CD such as the ward admission, operating theater, spinal analgesia, and moment of birth. The primary outcome measure was a change in score on the Visual Analogue Scale for Anxiety (ΔVAS-A) measured at admission for CD, compared with the baseline VAS-A score. RESULTS: A total of 97 women were included for analysis. The baseline characteristics were similar in both groups, except for a significantly higher level of education in the control group. There was no significant decrease in the VAS-A score of the women in the VR group (n=49) compared with those in the control group (n=48; ΔVAS-A=1.0; P=.08; 95% CI -0.1 to 2.0). Subgroup analysis for the group of women with a history of emergency CD showed a trend toward decreased preoperative anxiety, despite the small sample size of this subgroup (n=17; P=.06). Of the 26 participants who provided completed questionnaires, 22 (85%) in the VR group reported feeling more prepared after seeing the VR video; of the 24 participants' partners who completed the questionnaires, 19 (79%) agreed with the participants. No discomfort or motion sickness was reported. CONCLUSIONS: A VR video may help patients and their partners feel better prepared when planning a CD. This study showed that VR does not lead to a decrease in preoperative anxiety. However, subgroups such as women with a history of emergency CD may benefit from VR videos.
