Purpose This study aimed to compare the effects of using single and double surgical masks (SM) on maternal oxygen saturation in pregnant women. Methods In this prospective study, single or double SM were worn by term pregnant women who applied for routine controls. The vital signs of the participants such as oxygen saturation, pulse, respiratory rate, fever, systolic and diastolic blood pressure were measured at admission and 30 min later. Results There were 223 participants in the single SM group and 231 participants in the double SM group. Thirty minutes after putting on the mask, there was no significant difference in the proportion of patients whose oxygen saturation fell below 95 (3.6 vs 5.6%, p = 0.301). No significant difference was observed between the admission and 30 min oxygen saturation levels of the pregnant women in the single SM group. However, maternal oxygen saturation after 30 min of the pregnant women in the double SM group was significantly lower (97.4 ± 1.1 vs 96.6 ± 1.3, p < 0.001). No significant changes were observed in the vital signs of either groups. Conclusion When using double SM, oxygen saturation is significantly reduced compared to pre-mask values. Nevertheless, it seems difficult to say that these decreases have clinical significance.

Objective: In this study, we aimed to investigate the role of peripheral blood parameters and the systemic inflammatory index (SII) in the diagnosis of hyperemesis gravidarum (HG) and whether they have a predictive value in determining the length of hospital stay and the risk of rehospitalization in HG cases. Materials and methods: In the retrospective study, pregnant women who were hospitalized due to HG (n = 112) and pregnant women who were completely healthy (n = 112) were matched for gestational age. Peripheral blood inflammation parameters of the entire study group were evaluated. The length of hospital stay and rehospitalization rate for HG cases were recorded. A total of 224 patients, 112 (50%) in the control group and 112 (50%) in the HG group were included in the study. There was a positive correlation between increased ketonuria and length of hospitalization, peripheric blood parameters, and SII. The degree of ketonuria was found to be statistically insignificant in determining the risk of rehospitalization (p = 0.927). About 28.57% (n = 32) of all HG cases were readmitted to the hospital. When the length of hospital stay was considered, SII was found to be statistically significant in hospitalizations lasting more than 2 days (p = 0.001), but not in rehospitalizations (p = 0.3). Conclusion: SII is significant in diagnosing and determining hospitalization of HG. It is sufficient to determine the length of hospital stay but not rehospitalization risk, which is an indicator of disease severity. Key words: hyperemesis gravidarum – hospitalization – inflammation markers – systemic inflammatory index

Purpose: This study aimed to investigate the surgical outcomes and safety of cesarean section myomectomies. Methods: This retrospective study was performed between January 2015 and August 2022, at a single university hospital. Pregnant women diagnosed with myoma uteri who underwent C/S (cesarean section) myomectomy and pregnant women without myoma as the control group and only underwent C/S were included in the study. Patients' age, gravida, parity, abortion, body mass index (BMI), delivery week, previous delivery type, myoma size, type, number, localization, preoperative and postoperative hemoglobin (Hb) values and postoperative Hb changes, operation time, hospital stay, blood transfusion need and amount, and postoperative complications were recorded from the hospital archive system. The obtained data were compared between the two groups. Results: A total of 283 patients underwent C/S myomectomy and 324 patients who did not have myoma underwent only C/S. Duration of operation, length of hospital stay, postoperative blood transfusion need and amount of blood transfusion, preoperative Hb, and change of Hb values were statistically significantly higher in the C/S myomectomy group (p<0.01, p<0.01, p=0.005, p= 0.006, p<0.01, p<0.01, respectively). A statistically significant weak positive correlation was observed between fibroid size and hospital stay (ρ=0.133). There was a statistically significant weak positive correlation between the size of myoma and the amount of blood transfused (ρ=0.120). Conclusion: Myomectomy during cesarean section has a low complication rate and saves patients from the necessity of a second operation.
