RESUMO
Objective:To evaluate the perioperative and follow-up data of carotid artery stenting (CAS)+ coronary artery bypass grafting (CABG) and CABG alone, and to assess the safety and efficacy of CAS in the treatment of severe stenosis of the carotid artery in combination with asymptomatic carotid artery stenosis.Methods:A retrospective analysis of 700 CABG patients combined asymptomatic carotid artery severe stenosis at Beijing Anzhen Hospital, Beijing Chaoyang Hospital, and Beijing Tiantan Hospital from January 2018 to December 2022 was performed. According to whether or not underwent CAS treatment, they were divided into the CAS-CABG group(116 cases)and the CABG-only group(584 cases). The mean age of the CAS-CABG group was (64.8±7.3) years, and all of them underwent unilateral CAS surgery only; the mean age of the CABG only group was (65.5±7.6) years. The main results of the patients in the two groups were compared at 30 days after the operation and follow-up period.Results:The early postoperative stroke rate was significantly lower in the CAS-CABG group(2.6% vs. 9.1%, P=0.02), while the combined procedure did not increase the rates of mortality and adverse events during follow-up. Subgroup analysis revealed that there was no significant difference in stroke rates between the two procedures for asymptomatic unilateral carotid artery stenosis, advanced age, history of atrial fibrillation, and history of stroke were independent risk factors for early stroke in CABG for asymptomatic unilateral carotid artery stenosis. Conclusion:CAS-CABG is safe and effective in the treatment of coronary artery disease combined with asymptomatic carotid artery stenosis, and can reduce the incidence of early postoperative stroke in patients. CABG patients with asymptomatic carotid stenosis should be rationally screened for prophylactic CAS to reduce the risk of postoperative stroke in these patients.
RESUMO
Objective To evaluate the effect of serratus plane block (SPB) combined with general anesthesia and SPB with patient-controlled nerve analgesia (PCNA) after surgery on the early postoperative quality of recovery in the patients undergoing radical mastectomy.Methods Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ female patients,aged 18-64 yr,weighing 45-70 kg,scheduled for elective unilateral modified radical mastectomy under general anesthesia,were assigned into 3 groups (n=20 each) using a computer software:SPB and general anesthesia plus patient-controlled intravenous analgesia (PCIA) group (SG+PCIA group),SPB and general anesthesia plus SPB with PCNA group (SG+PCNA group),and general anesthesia plus PCIA group (G+PCIA group).Ultrasound-guided ipsilateral SPB was performed before anesthesia induction.Analgesia was maintained with propofol-remifentanilsevoflurane,rocuronium or vecuronium was intermittently injected to maintain muscle relaxation.PCIA solution contained tramadol 800 mg and flurbiprofen axetil 100 mg in 54 ml of normal saline,and the PCA pump was set up to deliver a 2 ml bolus dose,with a 15 min lockout interval and background infusion at a rate of 0.5 ml/h after a loading dose of 5 ml.The location of the indwelling catheter was confirmed again using ultrasound at the end of surgery,PCNA solution contained 1％ ropivacaine 500 mg in 250 ml of normal saline,and the PCA pump was set up to deliver a 5 ml bolus dose,with a 45 min lockout interval and background infusion at a rate of 5 ml/h after a loading dose of 5 ml.The PCA pumps were used until 48 h after surgery.The automatic key was pressed when pain scores (numerical rating scale [NRS] scores) ≥ 4 at rest or during activity (at 45° ipsilateral upper extremity-up tilt).Quality of Recovery-40 (QoR-40) score was used to assess the early postoperative quality of recovery at 24 and 48 h after surgery.NRS scores at rest or during activity were recorded at 6,8,12,24 and 48 h after surgery.The total pressing times of PCA and occurrence of adverse reactions such as respiratory depression,pruritus,infection at the puncture site or pneumothorax were also recorded.Results Compared with group G+PCIA,the postoperative QoR40 scores were significantly increased,NRS scores at rest or during activity were decreased at each time point after surgery,and the total pressing times of PCA were reduced in SG+PCIA and SG+PCNA groups,the incidence of nausea and vomiting was significantly decreased in group SG+PCIA,and the incidence of nausea and vomiting and dizziness was significantly decreased in group SG+PCNA (P＜0.05 or 0.01).Compared with group SG+PCIA,the postoperative QoR-40 scores were significantly increased at 24 h after surgery,and NRS scores at rest or during activity were decreased after surgery in group SG+PCNA (P＜ 0.05 or 0.01).Conclusion SPB combined with general anesthesia and SPB with PCNA after surgery can raise the early postoperative quality of recovery in the patients undergoing modified radical mastectomy.
