Effect of different anesthetic modalities with multimodal analgesia on postoperative pain level in colorectal tumor patients.

BACKGROUND: According to clinical data, a significant percentage of patients experience pain after surgery, highlighting the importance of alleviating postoperative pain. The current approach involves intravenous self-control analgesia, often utilizing opioid analgesics such as morphine, sufentanil, and fentanyl. Surgery for colorectal cancer typically involves general anesthesia. Therefore, optimizing anesthetic management and postoperative analgesic programs can effectively reduce perioperative stress and enhance postoperative recovery. The study aims to analyze the impact of different anesthesia modalities with multimodal analgesia on patients' postoperative pain. AIM: To explore the effects of different anesthesia methods coupled with multi-mode analgesia on postoperative pain in patients with colorectal cancer. METHODS: Following the inclusion criteria and exclusion criteria, a total of 126 patients with colorectal cancer admitted to our hospital from January 2020 to December 2022 were included, of which 63 received general anesthesia coupled with multi-mode labor pain and were set as the control group, and 63 received general anesthesia associated with epidural anesthesia coupled with multi-mode labor pain and were set as the research group. After data collection, the effects of postoperative analgesia, sedation, and recovery were compared. RESULTS: Compared to the control group, the research group had shorter recovery times for orientation, extubation, eye-opening, and spontaneous respiration (P < 0.05). The research group also showed lower Visual analog scale scores at 24 h and 48 h, higher Ramany scores at 6 h and 12 h, and improved cognitive function at 24 h, 48 h, and 72 h (P < 0.05). Additionally, interleukin-6 and interleukin-10 levels were significantly reduced at various time points in the research group compared to the control group (P < 0.05). Levels of CD3+, CD4+, and CD4+/CD8+ were also lower in the research group at multiple time points (P < 0.05). CONCLUSION: For patients with colorectal cancer, general anesthesia coupled with epidural anesthesia and multi-mode analgesia can achieve better postoperative analgesia and sedation effects, promote postoperative rehabilitation of patients, improve inflammatory stress and immune status, and have higher safety.

[Effect of Ropivacaine Combined with Dexmedetomidine for Serratus Anterior Plane Block Plus Patient-Controlled Intravenous Analgesia on Postoperative Recovery Quality of Patients Undergoing Thoracoscopic Radical Resection of Lung Cancer].

Objective: To study the postoperative analgesic effect of ropivacaine combined with dexmedetomidine for serratus anterior plane block (SAPB) under ultrasound visualization plus patient-controlled intravenous analgesia (PCIA) in patients undergoing thoracoscopic radical resection of lung cancer. Methods: A total of 129 patients undergoing elective thoracoscopic surgery were enrolled. The patients were randomly assigned to three groups ( n=43 in each group), a normal saline group (control group), a ropivacaine mesylate group (Group R) and a ropivacaine mesylate combined with dexmetomidine hydrochloride group (Group RD). After operation, ultrasound-guided SAPB was performed and patients in the three groups received the injection of 0 mL of 0.9% normal saline, 25 mL of 0.5% ropivacaine, and 25 mL of 0.5% ropivacaine+1 µg/kg dextrometomidine hydrochloride mixture, respectively. In addition, PCIA was used for all the patients. The button on the PCIA pump was pressed when the postoperative pain visual analogue score (VAS)≥4 on coughing, and rescue analgesic of sufentanil was given intravenously at 2.5 µg/bolus. The primary outcome was the VAS scores at rest and on coughing at 10 min (T 1), 6 h (T 2), 12 h (T 3), 24 h (T 4), and 48 h (T 5) after extubation. The secondary outcomes included hemodynamics, the quality of sleep for the first 3 nights after operation, number of times the button on the PCIA pump was pressed, intraoperative and postoperative opioid dosage, time of first postoperative rescue analgesic, duraion of intubation, length of stay at the hospital, adverse reactions, etc. Results: Compared with those of the control group, the VAS scores of the Group R and Group RD were significantly lower at 10 min, 6 h, and 12 h after extubation ( P<0.05). In comparison with Group R, the number of patients requiring rescue analgesia, the time of first postoperative rescue analgesic, the number of times the button on the PCIA pump was pressed, and the total dose of rescue sufentanil were all significantly lower ( P<0.05) in the Group RD. Patients in the Group RD had better sleep quality in the second and third nights after operation and lower incidence of nausea and vomiting ( P<0.05). Conclusion: 0.5% ropivacaine and 1 µg/kg dexmedetomidine SAPB combined with PCIA can significantly reduce postoperative pain and improve postoperative recovery quality in patients undergoing thoracoscopic radical resection of lung cancer.

Consistency of postoperative pain assessments between nurses and patients undergoing enhanced recovery after gynaecological surgery.

AIMS AND OBJECTIVES: To explore the consistency of pain intensity and pain location assessed by nurses and patients in gynaecology undergoing enhanced recovery after surgery pathway. BACKGROUND: Several studies have shown that clinical nurses' assessment of patients' pain is not always accurate. Little is known about the accuracy of nurses' pain assessments for gynaecological patients. Postoperative pain assessment and management is an essential part of enhanced recovery after surgery. DESIGN: Comparative cross-sectional study. METHODS: A total of 160 patients were recruited and only 85 patients and 17 nurses participated. Patients and nurses recorded pain scores (using an 11-point Numeric Rating Scale) and pain location (incision pain, surgical area pain in the abdominal cavity, other pain or no pain) on Pain Assessment Forms at 4 hr after surgery and on the first and second postoperative days. We used the STROBE guidelines to report our study. RESULTS: The patients' pain score was higher than that of nurses from 4 hr to second day after laparoscopic surgery at rest. The pain scores of both nurses and patients decreased over this period of time. All the intraclass correlation coefficients were between 0.214-0.296. At the three time points, surgical area pain in the abdominal cavity and abdominal incision pain were the main pain areas. All the kappa coefficients were between 0.164-0.255. CONCLUSIONS: The consistency of postoperative pain assessment about pain score and pain location between nurses and patients was not high. We should attach importance to systematic pain assessment, and more detailed enhanced recovery after surgery pathways should be developed about pain assessment. RELEVANCE TO CLINICAL PRACTICE: Continuing education for nurses regarding pain assessment is necessary. Nurses should accept the patient's self-reported pain. There should be a step that gives more time for pain assessment in enhanced recovery after surgery pathways.
