Objective To survey the cognition of women to labor analgesia in Shanghai.Methods One hundred randomized pregnant women filled in the questionnaires at obstetric outpatient department in our hospital.One hundred women took part in the survey after labor at maternity ward,ninety of whom underwent patient-controlled epidural analgesia with 0.1% ropivacaine plus 0.002% fentanyl,and the rest 10 inhaled 50% nitrous oxide mixed with 50% oxygen.Results Before labor analgesia,98% pregnant women thought that the labor was painful;42% were nervous and frightened about the labor pain;90% knew nothing about labor analgesia;63% had no idea about the influences of labor analgesia on infants;and 14% worried that analgesia would have side effects on infants.After labor analgesia,99% women were satisfied with its pain relief effect;100% considered that labor analgesia was necessary;and 20% worried about their newborn babies.Conclusion It is necessary to popularize the knowledge about labor analgesia,which is an important part of work on labor health.

Objective:To explore the efficacy, safety, and feasibility of single port laparoscopic liver resection via umbilical cord, and summarize its surgical experience.Method:A retrospective analysis was conducted on 39 patients who underwent liver resection surgery at the Department of Hepatobiliary and Pancreatic Surgery, the Affiliated Hospital of Qingdao University from February 2022 to September 2023. There were 19 patients in the transumbilical single-port laparoscopic group, including 5 males and 14 females, aged (49.6±2.5) years. There were 20 patients in the multi-port laparoscopic group, including 7 males and 13 females, aged (49.9±3.1) years. The intraoperative blood loss, operation time, intestinal recovery time, postoperative hospital stay and postoperative complications were compared between the single-port group and multi-port group.Results:All 39 patients successfully completed the surgery without any additional foramen or conversion to open surgery. The operation time of the single hole group (166.3±59.0) min was longer than that of the multi-port group (123.2±48.0) min, and the difference was statistically significant ( t=2.50, P=0.020). There were no statistically significant differences in intraoperative blood loss, intestinal recovery time, postoperative hospital stay, and postoperative complications between these two groups (all P>0.05). All patients had no postoperative complications such as bleeding, infection, or bile leakage. Follow up for 3~21 months showed no recurrence of primary diseases such as hepatic hemangioma, hepatic adenoma, and intrahepatic bile duct stones. The aesthetic effect of the umbilical incision in the single orifice group was significant, and patient satisfaction was 100%. Conclusion:Umbilical single-port laparoscopic liver resection surgery is safe and feasible, with significant minimally invasive and aesthetic effects.
