The ultrasonically activated device harmonic scalpel is often used for dissection of the uterine cervix during laparoscopic surgery. To evaluate thermal damage of harmonic scalpel during laparoscopic hysterectomy, cervical margin tissues were immunohistochemically examined for CD31 antigen in the vessel structures. CD31 antigen was detected more in vessel structures in tissues dissected with the harmonic scalpel than with monopolar electrodes. We considered that harmonic scalpel is a safe surgical device with minimal thermal damage to tissues surrounding the uterine cervix at laparoscopic hysterectomy.
Maternal Heart Rate and Fetal Heart Rate Characteristics in Response to Labor
Junsuke Muraoka, Seishi Furukawa*, Hiroshi Sameshima
Maternal heart rate (MHR) monitoring during labor has some benefits in certain situations. For example, it is well known that maternal arrhythmias are frequently seen during pregnancy in patients with low risk and congenital heart disease , and the monitoring of MHR seems to be necessary in such cases. In the case of obstetrical complications such as placental abruption or chorioamnionitis, the monitoring of MHR is useful for the early recognition of altered homeostasis due to bleeding or infection. Apart from morbidity assessment of pregnant women, we often found that the monitoring of MHR was effective in distinguishing it from the fetal heart rate (FHR) during labor.
Gynecology and Obstetrics
Obstetrics and Gynecology is the medical specialty that involves two sub-section of obstetrics covering pregnancy, childbirth and the postpartum period and gynecology covering female reproductive system vagina, uterus, and ovaries. This both fields are dedicated towards female health, reproductive organs, and management of pregnancy.
