The total satisfaction rate of patients in the implementation group was 96.55%, and that in the control group was 77.59%, which difference was statistically significant (P<0.05). Conclusion Special preventive nursing measures could improve the catheterization accuracy of ultrasound-guided PICC for elderly patients, reduce the risk of catheter-related complications, relieve the psychological pressure of patients, and improve patients’ satisfaction.

目的 探讨术前超声有关指标在预测腹腔镜胆囊切除术(LC)难易度中的价值,以预判LC手术的风险,减少手术的盲目性。方法 257例术前获得的超声参数包括:胆囊大小、胆囊壁厚度、胆囊黏膜面情况、胆囊内胆汁透声情况、胆囊结石最大直径、胆囊颈部结石嵌顿情况。术后资料包括手术时间、术中出血量、是否放置引流管、是否中转进腹手术、术后并发症。计算257例手术的平均时间并将其称为标准手术时间,将超过标准手术时间的、术中出血≥100 mL、术后放置引流管、中转开腹的手术定义为有难度手术。以此标准将257例手术患者分为容易组和困难组,应用χ²检验进行单因素分析,LC手术困难的危险因素;再对这些指标进行Logistic多元回归分析,确定预测LC难易的独立危险因素。结果 单因素分析,术前超声指标:胆囊大小>50 cm²、胆囊壁厚度>4 mm、胆囊结石最大直径>2 cm、胆囊颈部结石嵌顿、胆囊内胆汁透声差,是LC难度的危险因素。Logistic多元回归分析证实,胆囊大小、胆囊壁厚度、胆囊内胆汁透声差、胆囊颈部结石嵌顿等4项超声检测指标是困难LC的独立危险因素。结论 手术前胆囊超声检查可以客观评估LC难度,对指导术者选择LC病例具有一定的预测价值。

Objective To explore the value of preoperative ultrasound indicators in predicting the difficulty of laparoscopic cholecystectomy (LC), in order to predict the risk of LC surgery and reduce the blindness of surgery. Methods The preoperative ultrasonographic parameters of 257 cases included gallbladder size, gallbladder wall thickness, gallbladder mucosal surface, bile sound transmission in gallbladder, maximum diameter of gallstone, and gallstone incarceration in gallbladder neck. Postoperative data included operation time, intraoperative blood loss, whether drainage tube was placed, whether transfer to abdominal surgery, and postoperative complications. The average operation time of the 257 cases was calculated and called the standard operation time, and the operation that exceeded the standard operation time, intraoperative bleeding ≥100 mL, postoperative drainage tube placing, and conversion of abdominal operation were defined as difficult operation. According to this standard, 257 patients were divided into the easy group and the difficult group. The χ² test was used for univariate analysis to identify the risk factors of difficult LC operation. Logistic multiple regression analysis was performed to determine the independent risk factors for predicting LC difficulty. Results According to unifactor analysis, preoperative ultrasound indicators: gallbladder size >50 cm², gallbladder wall thickness >4 mm, maximum diameter of gallstone >2 cm, gallbladder neck stone incarceration, and poor bile ultrasound transmission in gallbladder were risk factors for LC difficulty. Logistic multiple regression analysis confirmed that gallbladder size, gallbladder wall thickness, poor bile ultrasound transmission in gallbladder and stone incarceration in gallbladder neck were independent risk factors for difficult LC. Conclusions Ultrasound examination of gallbladder before operation could objectively evaluate the difficulty of LC, and had certain predictive value for guiding the surgeon to select LC cases.

目的 对比剖宫产术后子宫瘢痕妊娠(CSP)与对照组的相关数据,为及早诊断CSP提供帮助;对比不同超声分型CSP超声特征及治疗方式,为早期诊断和个体化治疗方案的制定提供客观依据。方法 回顾性分析我院收治的41例CSP患者及41例对照患者的超声声像图特征及相关临床指标,总结分析不同分型CSP患者所采取的治疗方式。结果 41例CSP患者与41例对照组比较,出现阴道流血的概率更高,差异有统计学意义(P<0.05);根据超声分型将CSP分为4型,分别为Ⅰ、Ⅱ、ⅢA及ⅢB型,Ⅰ型CSP患者与其他3型CSP比较,出现阴道流血的概率要高,差异有统计学意义(P<0.05);Ⅰ型CSP较Ⅱ、Ⅲ、ⅢA型子宫前壁肌层厚,差异有统计学意义(P<0.05);关于治疗:Ⅰ型CSP主要治疗方式为超声引导清宫术;Ⅱ型根据临床实际情况,每一种方式都可选择;Ⅲ型CSP主要采用子宫动脉栓塞后超声引导下清宫术,所有患者术中出血均不多,预后良好并顺利出院。结论 1.CSP患者与对照组临床指标对比有一定差异性,但不够特异,故为了及早的诊断CSP,对于有剖宫产史妇女再次妊娠的早孕检查,一定要明确妊娠囊与子宫前壁下段瘢痕及膀胱的关系;2.超声分型有助于制定针对CSP的个体化治疗方案,以改善患者预后。故诊断CSP的同时,还需对CSP进行准确的超声分型。

Objective To compare the data of cesarean scar pregnancy (CSP) after cesarean section with that of the control group, so as to provide help for the early diagnosis of CSP. To compare the ultrasonic characteristics and treatment methods of different ultrasonic types of CSP, so as to provide an objective basis for early diagnosis and individualized treatment. Methods The ultrasonographic features and related clinical indexes of 41 CSP patients and 41 control patients were analyzed retrospectively, the treatment methods adopted by patients with different types of CSP were summarized and analyzed. Results The probability of vaginal bleeding in 41 patients with CSP was higher than that in 41 control patients, the difference was statistically significant (P<0.05). According to ultrasonic classification, CSP is divided into four types: Ⅰ, Ⅱ, ⅢA and ⅢB. Compared with other 3 types CSPs, patients with type Ⅰ CSP had higher probability of vaginal bleeding, which difference was statistically significant (P<0.05). The main treatment of type Ⅰ CSP was ultrasound-guided uterine curettage, each method could be selected according to the actual clinical situation for type Ⅱ CSP, type Ⅲ CSP mainly adopted ultrasound-guided uterine curettage after uterine artery embolization. All patients had little intraoperative bleeding, good prognosis and been discharged successfully. Conclusions There were some differences in clinical indexes between CSP patients and control patients, but they were not specific enough. Therefore, in order to diagnose CSP as soon as possible, for the early pregnancy examination of second pregnancy in patients with cesarean section, we must clarify the relationship between gestational sac and scar of the lower part of the anterior wall of uterus and bladder. Ultrasound typing is helpful to formulate an individualized treatment plan for CSP patients to improve the prognosis. Therefore, accurate ultrasonic typing is also needed when diagnosing CSP.

Objective To investigate the effect of low mechanical index diagnostic ultrasound and low acoustic pressure therapy on contrast agent microbubbles. Methods Microbubbles were irradiated by diagnostic ultrasound with low mechanical index(MI) and low energy therapy under different acoustic pressure. To obtain the images, and analyze the change of microbubble concentration,the movement trend of microbubbles under different MI and different acoustic pressure were analyzed, to estimated stable cavitation or inertial cavitation of microbubbles. Results Stable cavitation was the main form of microbubbles under low mechanical index (< 0.2) diagnostic ultrasound and low acoustic pressure (< 0.15Mpa). With the increase of mechanical index or acoustic pressure, stable cavitation and inertial cavitation coexisted. When mechanical index > 0.3 or sound pressure > 0.2MPa, microbubbles were mainly inertial cavitation. Conclusion The cavitation effects of microbubbles under low mechanical index and low acoustic pressure are different. With the increase of mechanical index or acoustic pressure, the damage of microbubbles increases, and main effect is the inertial cavitation.

Objective To understand the detection effect of internal carotid artery ultrasound combined with transcranial Doppler on patients with postpartum depression, and to provide valuable clues for clinical postpartum depression treatment. Methods The data of 78 parturients who met the diagnostic criteria for depression in our hospital from March 2018 to February 2020 were collected. The data were reviewed and set as the study group. At the same time, 78 healthy parturients were selected as the control group.We used internal carotid artery ultrasound to detect the carotid blood flow parameters [carotid artery diameter (D), peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI)] of the two groups of parturients, and combined transcranial color Doppler ultrasound (TCD) to monitor the blood flow velocity of the arteries and vertebrobasilar artery (VA-BA), middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) of the two groups of women. The changes in maternal RI and PI between the two groups were analyzed, and the above data were statistically analyzed and compared between groups. Results Compared with the control group, the D and EDV levels of the study group were decreased, while the RI value was increased, the difference was statistically significant (P<0.05). The comparison of PSV between the two groups was not statistically significant (P>0.05). The arterial blood flow velocity in MCA, ACA, and PCA of the depressed women in the study group were accelerated and the differences were statistically significant (P<0.05). The blood flow velocity of VA-BA of the depressed women in the study group was slower than that of the control group, and the difference was statistically significant (P＜0.05). RI and PI values of depressed women in the study group were compared with those of the control group. There was no statistically significant difference between the groups (P>0.05). Among 78 depressed women, 62 had abnormal cerebral artery blood flow. The abnormal detection rate was 79.49% (62/78). Conclusion Transcranial Doppler examination showed that the blood flow of the three cerebral arteries of the postpartum depressed women was increased, while the blood flow of the vertebrobasilar arteries slowed down, which indicated that the depressed women had cerebral artery spasm and the cerebral blood supply was obviously insufficient. The internal carotid artery ultrasound showed there were certain changes in carotid blood flow parameters of depressed mothers, which can provide a certain reference for the treatment of patients with postpartum depression.

目的 探讨超声引导下宫颈癌根治术的应用效果及对患者远期生存率的影响。方法 选取本院2015年1月—2017年12月共收治的70例宫颈癌患者作为研究对象,将2016年7月—2017年12月纳入的患者作为观察组,2015年1月—2016年6月纳入的患者作为对照组,各35例,给予对照组患者常规腹腔镜根治术,给予观察组患者超声引导定位下腹腔镜宫颈癌根治术联合高强度凝聚超声热凝技术治疗。对比两组患者的治疗效果、远期生存率与复发率以及术后6个月、1年、2年、3年的FACT-G评分情况。结果 两组疾病控制率对比无差异(97.14% vs 85.71%,P＞0.05);观察组的治疗总有效率为高于对照组的(85.71% vs 60.00%,P＜0.05);观察组和对照组患者1年生存率对比无差异(P＞0.05),观察组2年、3年生存率高于对照组(P＜0.05),观察组和对照组1年局部复发率对比无差异(P＞0.05),观察组的2年、3年局部复发率低于对照组(P＜0.05);观察组术后6个月、1年、2年、3年的FACT-G评分高于对照组(P＜0.05)。结论 应用超声引导定位下腹腔镜宫颈癌根治术联合高强度凝聚超声热凝技术治疗宫颈癌能够提升患者的治疗效果,减少疾病复发和提高远期生存率,提升患者的生存质量,值得临床应用推广。

Objective To investigate the application effect of ultrasound-guided radical hysterectomy for cervical cancer and its influence on the long-term survival rate of patients. Methods A total of 70 patients with cervical cancer admitted from January 2015 to December 2017 were selected as the research subjects, and the patients enrolled from July 2016 to December 2017 were selected as the observation group, patients from January 2015 to June 2016 as the control group, each with 35 cases. The control group was given conventional laparoscopic radical hysterectomy, and the observation group was given ultrasound-guided laparoscopic radical hysterectomy combined with high-intensity ultrasound coagulation technology. The treatment effect, long-term survival rate, recurrence rate and FACT-G scores 6 months, 1 year, 2 years and 3 years after operation were compared between the two groups. Results There were no significant differences in disease control rates between the two groups (97.14% vs 85.71%, P>0.05); the total effective rate of treatment in the observation group was higher than that in the control group (85.71% vs 60.00%, P<0.05). There was no significant difference in the 1-year survival rate between the observation and the control group (P>0.05). The 2-year and 3-year survival rate of the observation group were higher than that of the control group (P<0.05). There was no significant difference in comparison of 1-year local recurrence rate between the observation group and the control group (P>0.05). The 2-year and 3-year local recurrence rate of the observation group were lower than that of the control group (P<0.05). FACT-G scores in the observation group after surgery at 6 months, 1 year, 2 years, and 3 years were significantly higher than the control group (P<0.05). Conclusion The application of ultrasound-guided laparoscopic radical hysterectomy combined with high-intensity ultrasound coagulation in the treatment of cervical cancer can improve the treatment effect, reduce disease recurrence rate, increase long-term survival rate, and improve the quality of life of patients, which is worthy of clinical application and promotion.
