Comparison of the Effects of Propofol and Sevoflurane Anesthesia on Optic Nerve Sheath Diameter in Robot-Assisted Laparoscopic Gynecology Surgery: A Randomized Controlled Trial

Optic nerve sheath diameter (ONSD) is used as a surrogate parameter for intracranial pressure. This study was conducted to evaluate the effect of the anesthetics (sevoflurane and propofol) on ONSD in women undergoing robotic surgery. The 42 patients who were scheduled for robot-assisted gynecology surgery were randomly allocated to the sevoflurane group or the propofol group. ONSD was recorded at 10 min after the induction of anesthesia (T0); 5 min, 20 min, and 40 min after carbon dioxide pneumoperitoneum was induced and the patients were put in a steep Trendelenburg position (T1, T2, and T3, respectively); and at skin closure after desufflation of the pneumoperitoneum (T4). Patients were observed for postoperative nausea and vomiting (PONV) during the immediate postoperative period. The propofol group had significantly lower ONSD than the sevoflurane group at T3. Mean ONSD values continuously increased from T0 to T3 in both groups. Two patients in the sevoflurane group experienced PONV. This study suggests that propofol anesthesia caused a lower increase in ONSD than sevoflurane anesthesia.

The effects of epidural analgesia using low-concentration local anesthetic during the entire labor on maternal and neonatal outcomes: a prospective group study

PURPOSE

The purpose of this study was to study the impact of epidural analgesia using low-concentration local anesthetic during the entire labor on maternal and neonatal outcomes.

METHODS

The authors enrolled 2310 parturient mothers who underwent vaginal delivery at their hospital since January 1, 2019. The parturients were allocated either into the analgesia or into the non-analgesia groups based on whether they received analgesia during the delivery process. To investigate the effects of epidural analgesia using low-concentration local anesthetic on maternal and neonatal outcomes, the authors assessed between-group differences in the labor duration, newborn Apgar score, and maternal and neonatal outcomes.

RESULTS

Compared to the non-analgesia group, the first and second labor stage durations in the analgesia group were significantly longer. Similarly, the analgesia group had a higher frequency of oxytocin injections, Category II and III fetal heart rate tracing during labor, and intrapartum fever development. Further, the need for episiotomy and assisted vaginal delivery was higher in the analgesia group than that in the non-analgesia group. Regarding neonatal outcomes, the neonatal hospitalization rate and incidence rate of umbilical cord blood pH < 7.2 were higher in the analgesia group than those in the non-analgesia group. However, there were no significant between-group differences in the incidence rates of stained amniotic fluid, mild neonatal asphyxia, and severe perinatal asphyxia.

CONCLUSION

Patient-controlled epidural analgesia using low-concentration local anesthetic during the entire labor did not increase the incidence rate of severe adverse outcomes in neonates born through vaginal delivery; however, it increased the delivery duration, and thus, the chance of possible perinatal interventions.
