It is safe to administer propofol in combination with remifentanil by continuous infusion after the bolus dose for the induction of anesthesia during cesarean section. Prolonging the I-D interval within a certain limit will not have any significant influence on the fetus.
The current study aimed to observe the effects of sufentanil and remifentanil combined with propofol in target-controlled infusion (TCI) on perioperative stress reaction in elderly patients. A total of 80 elderly patients requiring general anesthesia were recruited. They were divided into four groups (each n=20) according to different target concentrations of remifentanil and sufentanil. These target concentrations were: 4 ng/ml remifentanil + 0.2 ng/ml sufentanil for group I; 3 ng/ml remifentanil + 0.3 ng/ml sufentanil for group II; 2 ng/ml remifentanil + 0.5 ng/ml sufentanil for anesthesia induction and post-intubation 3 ng/ml remifentanil + 0.2 ng/ml sufentanil for anesthesia maintenance for group III; and 5 ng/ml remifentanil for anesthesia induction and post-intubation 4 ng/ml remifentanil for anesthesia maintenance for group IV. Norepinephrine (NE), epinephrine (E) and angiotensin II (Ang II) levels in plasma were measured prior to the induction of anesthesia, as well as at several different time-points following surgery. The numbers of intraoperative severe hemodynamic fluctuation, postoperative eye-opening and extubation time, and post-extubation restlessness and pain scores were recorded. Group IV had a larger circulation fluctuation control number and higher levels of NE, E and Ang II at 3 h after surgery than any other group (P<0.01). Although group IV had shorter postoperative eye-opening and extubation times compared with the other groups (P<0.05), it also had higher restlessness and pain scores (P<0.01). The combined use of sufentanil and remifentanil stabilizes perioperative hemodynamics and reduces stress hormone levels.

Allogeneic blood transfusion is an important component in the treatment of postpartum hemorrhage. Short-term risks include acute transfusion reactions, hemolytic anemia, and transfusion-related acute lung injury, whereas long-term risks include immunosuppression. One method to reduce the need for allogeneic packed red blood cell (PRBC) transfusion after cesarean delivery (CD) is to use autologous blood transfusion obtained via intraoperative cell salvage (ICS). Consensus statements suggest that ICS is particularly beneficial in cases of anticipated massive blood loss—>20% or more of the patient’s estimated blood volume. In the current study, the authors assessed allogeneic transfusion rates before and after implementation of a targeted ICS infusion program in women undergoing CD at the Ningbo Women and Children’s Hospital (NWCH) in China.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
