RESUMEN
ObjectiveThis study aims to explore the effect of ultrasound-guided superficial parasternal intercostal plane block on the quality of recovery and postoperative analgesia in patients undergoing sternotomy cardiac surgery. MethodsA total of 64 patients undergoing sternotomy cardiac surgery were selected for this study. They were randomly divided into two groups： one group received a superficial parasternal intercostal plane block with ropivacaine （the ropivacaine group）， while the other was given normal saline （the normal saline group）. The primary outcome was the Quality of Recovery-15 （QoR-15） score on postoperative day 1 in both groups， accompanied by a comparative analysis of the pain score and opioid usage. ResultsCompared with the normal saline group， the ropivacaine group exhibited a significantly higher QoR-15 score on postoperative day 1［（89.60±13.24） vs （81.18±12.78）， P=0.012］. The numerical rating scale at rest was significantly lower［（3.03±0.72） vs （4.26±0.93）， P<0.001］， and the numerical rating scale during coughing was also significantly reduced ［（4.40±0.89） vs （5.44±1.05）， P<0.001］. Concurrently， the cumulative morphine equivalent consumption during the initial 24 h postoperatively was significantly lower in patients who were administered the ropivacaine ［14.15 （4.95～30.00） mg vs 40.50 （19.25～68.18） mg， P=0.002］， and there was also a notable decrease in the rescue analgesia ［0.00 （0.00～0.00） mg vs 0.00 （0.00～100.00） mg， P=0.007］. ConclusionUltrasound-guided superficial parasternal intercostal plane block can significantly enhance the overall quality of recovery in patients undergoing sternotomy cardiac surgery on postoperative day 1. The technique contributes to improved postoperative analgesic effects and a reduction in opioid usage， thereby facilitating early postoperative recovery.
RESUMEN
Objective:To analyze the effect and safety of levonorgestrel-releasing intrauterine system(LNG-IUS) for the premenopausal patients with breast cancer who took tamoxifen as adjuvant therapy.Methods:From June 2014 to June 2016, 84 patients with breast cancer who met the inclusion criteria in the First People′s Hospital of Xiaoshan District were randomly divided into two groups according to the digital table.The treatment group (39 cases) underwent LNG-IUS insertion, while the control group (45 cases) received no LNG-IUS insertion.The general condition of patients before the use of tamoxifen and LNG-IUS was evaluated.Transvaginal ultrasound was used to measure the thickness of endometrium, hysteroscope was used for pathological examination of endometrium and the measurement of ER/PR expression, and blood lipid level was also detected.All above was done before the treatment of tamoxifen and LNG-IUS, 1 year after treatment and 2 years after treatment.Results:Before the therapy, there were no statistically significant differences between the two groups in general condition and uterine cavity condition(all P>0.05). After 1 year, the incidences of endometrial polyp, endometrial hyperplasia/secretion, benign lesion and endometrial atrophy in the treatment group were 2.6%, 5.1%, 15.4%, 76.9%, respectively, which in the control group were 6.7%, 20.0%, 17.8%, 55.6%, respectively.the differences between the two groups were statistically significant(χ 2=4.06, 4.22, all P<0.05). After 2 years, the incidences of endometrial polyp, endometrial hyperplasia/secretion, benign lesion and endometrial atrophy in the treatment group were 0.0%, 2.6%, 84.6%, respectively, which in the control group were 11.1%, 15.6%, 60.0%, respectively, the differences between the two groups were statistically significant(χ 2=4.608, 4.092, 6.203, all P<0.05). Conclusion:LNG-IUS can prevent the benign endometrial lesions of breast cancer patients caused by tamoxifen therapy after surgery, and can decrease the incidence of endometrial polyp and endometrial hyperplasia/secretion, while increase the incidence of endometrial atrophy, without increasing the recurrence risk of breast cancer.
