Combined lumbar muscle block and perioperative comprehensive patient-controlled intravenous analgesia with butorphanol in gynecological endoscopic surgery

Butorphanol inhibits angiogenesis and migration of hepatocellular carcinoma and regulates MAPK pathway

Butorphanol, a synthetic opioid, exerts analgesic and anti-inflammatory effects against pathogenic diseases. Butorphanol repressed malignant behaviors of tumor cells. In this study, the role of butorphanol in hepatocellular carcinoma was evaluated. Firstly, hepatocellular carcinoma cells were treated with butorphanol. The results showed that butorphanol decreased cell viability of hepatocellular carcinoma cells. Cell proliferation and metastasis of hepatocellular carcinoma cells were inhibited by butorphanol. Secondly, butorphanol suppressed angiogenesis, and reduced phosphorylation levels of p38 and JNK in hepatocellular carcinoma cells. Thirdly, butorphanol reduced in vivo tumor growth of hepatocellular carcinoma in nude mice. Butorphanol reduced tumor micro-vascular density (MVD) and repressed lung metastasis. In conclusion, butorphanol exerted anti-angiogenic and anti-metastatic effects on hepatocellular carcinoma and induced inactivation of MAPKs signaling.

Effect of Patient-Controlled Epidural Analgesia (PCEA) Based on ERAS on Postoperative Recovery of Patients Undergoing Gynecological Laparoscopic Surgery

Objective

To explore the effect of patient-controlled epidural analgesia (PCEA) based on enhanced recovery after surgery (ERAS) on the postoperative recovery of patients undergoing gynecological laparoscopic surgery.

Methods

Between January 2019 and December 2020, 90 patients scheduled for gynecological laparoscopic surgery and assessed for eligibility were recruited and randomly assigned at a ratio of 1 : 1 to receive either conventional analgesic management (regular group) or PCEA based on ERAS (ERAS group). Comparisons of postoperative rehabilitation indicators, visual analogue scale (VAS) score, self-care ability, complications, and nursing satisfaction were conducted between the two groups.

Results

The ERAS group had significantly shorter first exhaust time (FET), first defecation time (FDT), out-of-bed activity time (OAT), and length of stay (LOS) versus the regular group (P < 0.05). The VAS scores were significantly decreased after treatment, with lower results observed in the ERAS group (P < 0.05). The level of self-responsibility, self-concept, self-care skills, and health knowledge increased significantly in both groups after the intervention, and the ERAS group showed significantly higher results than the regular group (P < 0.05). The total incidence of complications in the ERAS group was significantly lower than that in the regular group (P < 0.05). Eligible patients given PCEA based on ERAS were associated with a higher nursing satisfaction (97.78%) versus conventional analgesic management (82.22%) (P < 0.05).

Conclusion

The application of ERAS for postoperative PCEA management in gynecological laparoscopy provides promising results by effectively enhancing the quality of surgery and promoting rapid postoperative recovery, with a good safety profile.
