This device can measure VO2, VCO2, and EE with sufficient accuracy for clinical decision-making within the neonatal and pediatric size range, including in the setting of tachypnea or hyperoxia.

in the immune range, 131 (25%) were in the non-immune range, and 6 (1%) had equivocal immunity. Only 89 (65%) non-immune mothers received the MMR vaccine prior to discharge. Of the 48 (35%) mothers who did not receive the vaccine, 54% was due to maternal refusal. CONCLUSION: The percentage of mothers with negative MIT in our sample was higher than expected. Negative titers to measles do not necessarily suggest non-immunity as some vaccinated individuals have negative titers but produce an immune response when exposed to measles. Given that proof of immunization may not be available, administering a booster dose of MMR vaccine to patients with a negative MIT is reasonable, especially during an outbreak.

INTRODUCTION: It has been suggested that cesarean delivery during labor is associated with increased maternal morbidity compared with cesarean delivery without labor. We sought to examine the morbidity associated with cesarean deliveries due to arrest of dilation. METHODS: We conducted a retrospective cohort study of all women undergoing cesarean delivery from January 2016 to June 2018 at a single hospital. Each chart was reviewed to examine the primary indication for cesarean delivery. We examined maternal morbidity including chorioamnionitis, blood transfusion, superficial and deep incisional surgical site infections (SSI), and endometritis. We compared outcomes between women who had cesarean delivery due to arrest of dilation and those for other indications. Multivariable logistic regression was used to calculate adjusted odds ratios (aOR) with 95% confidence intervals (95% CI). IRB approval: STUDY00000045. RESULTS: Of 2957 women who underwent cesarean delivery, 214 (7.2%) had a cesarean delivery due to arrest of dilation. The rate of chorioamnionitis rates was significantly higher with arrest of dilation compared to other indications for cesarean delivery (13.6% vs. 3.6%, P<.01). Women that had cesarean delivery due to arrest of dilation compared to those who had other indications had similar rates of blood transfusion (7.5% vs. 7.6%; aOR 1.31 [95% CI 0.77–2.25]), SSI (4.7% vs. 3.1%; aOR 1.84 (95% CI 0.93–3.67]), and endometritis (2.8% vs. 1.6%; aOR 1.78 [95% CI 0.74–4.30], respectively). CONCLUSION: In contrast to theoretical concern, we found that postpartum complications (blood transfusion and postpartum infections) are similar between cesarean delivery due to arrest of dilation and cesarean delivery for other indications.
