Abstract:
Objective:To evaluate the optimized efficacy of thoracic paravertebral nerve block and subcostal transversus abdominis plane block combined with general anesthesia for elderly patients undergoing thoracic combined with laparoscopic radical resection of esophageal cancer.Methods:Eighty American Society of Anesthesiologists physical status Ⅰ orⅡ patients of both sexes, aged 66-78 yr, weighing 46-80 kg, undergoing elective thoracoscopic combined with laparoscopic radical resection of esophageal cancer, were divided into 2 groups ( n=40 each) using a random number table method: general anesthesia group (group G) and thoracic paravertebral nerve block and subcostal transversus abdominis plane block combined with general anesthesia group (TSG group). Both groups received target-controlled infusion of propofol and remifentanil and intravenous injection of cisatracurium besilate for anesthesia induction and maintenance, with BIS value maintained at 45-60 during operation.Thoracic paravertebral nerve block on the affected side was performed under ultrasound guidance after the end of anesthesia induction, and 0.5% ropivacaine 15 ml was injected in TSG group.The patients were turned to the supine position after the thoracic operation was completed, and the bilateral subcostal approach to the transversus abdominis plane block was performed under ultrasound guidance, and 0.3% ropivacaine 20 ml was injected into each side.Sufentanil was used for patient-controlled intravenous anesthesia (PCIA) after operation.The background infusion rate was 0.05 μg·kg -1·h -1, PCA was 0.04 μg/kg, and the lockout interval was 10 min in group G. The background infusion rate was 0.03 μg·kg -1·h -1, PCA was 0.025 μg/kg, the lockout interval was 10 min in group TSG.Both groups received analgesia until 48 h after operation, and VAS score was maintained ≤3.When VAS score ≥ 4, tramadol 100 mg was intravenously injected for rescue analgesia.At 1 day before operation (T 0), immediately before anesthesia induction (T 1), at 1 h after emergence from anesthesia (T 2), and 4, 8, 12, 24 and 48 h after operation (T 3-7), venous blood samples were collected for determination of serum norepinephrine, epinephrine and cortisol concentrations (by enzyme-linked immunosorbent assay). The intraoperative consumption of remifentanil and occurrence of cardiovascular events were recorded.The pressing times of PCA, consumption of sufentanil and requirement for rescue analgesia within 48 h after operation were recorded.The occurrence of nerve block-related complications (hematoma at the puncture site, infection, local anesthetic poisoning, etc.) and adverse reactions such as nausea and vomiting, respiratory depression and pruritus were recorded within 48 h after the operation. Results:Compared with group G, the concentrations of serum epinephrine, norepinephrine and cortisol were significantly decreased, the consumption of intraoperative remifentanil and postoperative sufentanil and pressing times of PCA were reduced, the rate of rescue analgesia was decreased, scores of satisfaction with analgesia were increased, and the incidence of intraoperative cardiovascular events and postoperative adverse reactions such as nausea and vomiting, pruritus and respiratory depression were decreased in group TSG ( P<0.05). Conclusion:Thoracic paravertebral nerve block and subcostal transversus abdominis plane block combined with general anesthesia can reduce the perioperative consumption of opioids and inhibit perioperative stress responses and postoperative hyperalgesia with fewer adverse reactions when used for the elderly patients undergoing thoracic combined with laparoscopic radical resection of esophageal cancer.
