Postoperative Analgesia and Cesarean Section under General Anesthesia: Multicenter Study

Background: Neuraxial anesthesia with intrathecal morphine is the reference technique in cesarean section anesthesia for the management of postoperative analgesia. If there is a contraindication to this, general anesthesia is required. The objective of the study was to evaluate the analgesic effectiveness of 4 analgesic techniques performed during cesarean section under general anesthesia in two centers with different anesthetic practices (North Franche Comté Hospital and Omar Bongo Ondimba Army Training Hospital). Method: This is a retrospective and descriptive study over 2 years, from January 1, 2019 to December 31, 2020. It involved evaluating the analgesic effectiveness and tolerance of morphine in the epidural catheter, wound infiltration, intravenous analgesia and Transversus Abdominous Plane block (TAP block) from the post-anesthesia care unit (PACU) until the 4th post-operative day. Results: Of the 354 cesarean sections performed, 84 (11.14%) received general anesthesia. The average age was 32.27 years. Acute fetal distress was the first indication for cesarean section (45.2%), followed by hemorrhagic placenta previa (10.7%) and prolapse of the cord (8.33%). Morphine in the epidural catheter was the most used (47.6%) followed by parietal infiltration (36.9%), intravenous analgesia (13.1%) and TAP block (2.38%). The analgesic effectiveness was comparable between the techniques from postoperative day 0 to day 4. No difference in side effects. Postoperative morphine consumption was significantly reduced (p = 0.011) in the infiltration (9 mg) and TAP block (9mg) groups compared to the epidural catheter (16 mg) and intravenous analgesia (17 mg). No difference in 02 rehabilitation criteria (ambulation, first bowel movement). No difference in the occurrence of chronic pain. Conclusion: In the event of a cesarean section under general anesthesia, there are effective and well-tolerated alternatives to neuraxial anesthesia, particularly regional anesthesia techniques (nerve blocks), particularly in countries with low availability of morphine.

Comparative Study between General Anesthesia versus General Anesthesia Combined with Thoracic Epidural Analgesia on Cytokine Response in Laparoscopic Cholecystectomy Patients

Background and Objectives: The main benefits of laparoscopic surgery in comparison to open surgery involve the rapid discharge from recovery room, decreased postoperative hospital stays, reduced postoperative discomfort, easier getting back to work and faster return to ordinary daily life as well as cosmetic surgical wounds. The anesthesia type has an essential role in attenuation of the surgical stress and achievement of these advantages. We aimed to determine the outcome of giving general anesthesia in conjunction with thoracic epidural analgesia (TEA) compared to general anesthesia alone on stress response to surgery and anesthesia by investigating cytokine reaction (interleukin 6 and 8 levels), hemodynamic changes (BP, HR, RR, SPO2), and Visual Analogue Scale (VAS) scores postoperatively in patients subjected for laparoscopic cholecystectomy. Methods: This study included 40 patients aged 20 - 60 years old with American Society of Anesthesiologists physical status (ASA) I and II. They were planned for laparoscopic cholecystectomy at Aswan University Hospital from April 2017 to March 2018. They were randomly allocated into two groups. Group A (n. 20) received general anesthesia only and Group B (n. 20) received general anesthesia in conjunction with thoracic epidural analgesia using fentanyl and bupivacaine in the epidural catheter. Chi-square was applied to differentiate categorical variables, whereas comparison between continuous variables was done by using t-test. Two-tailed p < 0.05 was estimated as statistically significant. Results: As regards IL-6 and IL-8 post-operative there is significant difference (p < 0.05) between two groups during 2nd and 4th hr and 24th hr postoperative, with significantly increased postoperative levels of IL-6 and IL-8 in comparison to their preoperative baseline values. The largest increase in IL6 & IL8 levels was in group A (GA group). VAS score showed significant lower values in TEA group in comparison to GA group. No significant difference between groups as regard intraoperative and postoperative hemodynamic changes. Conclusion: Regional techniques including TEA attenuate and decrease cytokine reaction secondary to surgery which decreases inflammatory process and improves patient outcome and reduces pain score postoperatively.

目的比较硬膜外不同浓度的甲磺酸罗哌卡因复合七氟醚吸入全麻用于老年患者食管癌手术时生命体征的变化。方法 60例择期开胸食管癌手术老年病人随机分为2组,组1、组2术中硬膜外分别给予0.447%甲磺酸罗哌卡因与0.298%甲磺酸罗哌卡因。硬膜外成功后行全麻诱导插管,调节吸入七氟醚的浓度维持BIS值在50～55之间,记录术中各时刻MAP、HR、BIS、七氟醚的呼气末浓度(FESEV)。结果手术开始后90 min内组1 MAP、HR与基础值比较下降(P<0.05),组2 MAP、HR与基础值比较无显著差异(P>0.05),组1与组2比下降(P<0.05)。90 min后组1与组2 MAP、HR与T0比较无显著差异(P>0.05),两组间比较亦无显著差异(P>0.05)。组1与组2比较发生低血压与心动过缓的次数增加(P<0.05)。结论与0.447%甲磺酸罗哌卡因相比,硬膜外0.298%甲磺酸罗哌卡因复合七氟醚全麻用于老年患者食管癌手术,能够提供充分的镇痛,术中生命体征也更加平稳。

胸段硬膜外麻醉对食管癌术后心律失常的影响

食管癌是目前常见的上消化道恶性肿瘤，手术治疗是其主要治疗方法。由于食管癌手术创伤大、时问长，对多个器官和系统造成不良影响，术后常伴有并发症。心律失常是食管癌患者术后的常见并发症之一，严重影响食管癌患者的术后恢复。如何减少食管癌术后心律失常的发生一直是国际热点问题。近年来硬膜外麻醉复合全身麻醉广泛应用于食管癌手术。相关研究证明胸段硬膜外麻醉能够减少阿片类镇痛药、吸人麻醉药及肌肉松驰药的用量，提供良好的术后镇痛，而且促进术后肺功能的恢复，抑制交感神经兴奋，从而降低心律失常的发生率。本文就胸段硬膜外麻醉对食管癌术后心律失常的影响及机制做一综述。
