RESUMEN
AIM: To investigate the effect of the timing of satisfactory sedation with preoperative oral midazolam on anesthesia induction and recovery in children undergoing adenotonsillectomy. METHODS: A total of 147 children undergoing elective adenotonsillectomy, with ASA physical status orⅡ, aged 2-7 years were selected from November 2022 to June 2023 in the Second Affiliated Hospital of Wenzhou Medical University. The children were orally administered 0.5 mg/kg midazolam in preoperative waiting area and were divided into 10-20 min (rapid onset, M1 group) and 21-30 min (slow onset, M2 group) based on the satisfactory sedation time, or equal volume of sugar pear drink orally (blank control group, C group). Children in all three groups received a general anesthesia method of propofol+fentanyl combined with sevoflurane induction and sevoflurane maintenance. The primary outcome measures were the induction compliance checklist (ICC) score and the pediatric anesthesia emergence delirium (PAED) score in the post-anesthesia care unit (PACU) to assess the occurrence of emergence agitation (EA), and the secondary outcome measures included the parental separation anxiety scale (PSAS), sedation Ramsay score, surgery duration, recovery time, PACU stay time, discharge time, the incidence of perioperative respiratory adverse events (PRAE) and other adverse events in the ward. RESULTS: 147 children were included in the result analysis, with 49 cases in each group. The proportion of perfect induction (ICC=0) were significantly higher in two M groups than that in group C (95.9% vs. 91.8% vs. 61.2%, P=0.001). The maximum and average PAED score in PACU in group M1 showed a significantly higher (6.4±5.0 vs. 4.4 ± 4.1, P=0.029; 5.2 ± 4.5 vs. 3.4 ± 3.6, P=0.030), and the incidence of EA was significantly higher than those in group C (10.2% vs. 30.6%, P=0.022), and increased compared to the group M2 (OR= 0.581, 95%CI 0.231-1.463, P=0.354). There was no statistically significant difference in the maximum and average PAED scores, incidence of EA between group M2 and group C (P>0.05). The Ramsay score and PSAS score in two M groups were higher, PACU stay time and recovery time was longer than those in group C (P0.05). CONCLUSION: Preoperative oral midazolam can improve the ICC and PSAS scores of children during induction, but it also leads to prolonged recovery time and PACU retention time. The rapid onset of midazolam did not result in better induction and recovery quality, but instead increased the incidence of EA and postoperative pain score.
RESUMEN
Objective:To evaluate percutaneous mechanical thrombectomy (PMT) using Aspirex device for treating acute iliofemoral deep vein thrombosis (IFDVT).Methods:The clinical and follow-up data of 68 patients with IFDVT at our institution from Jan 2019 to Jun 2021 was retrospectively analyzed.Results:Twenty-six patients who had received PMT combined with auxiliary catheter directed thrombolysis (CDT) were included into group A, and 42 patients received CDT alone were into group B.The final thrombus clearance rates were more than 50%, and the clinical efficacy of thrombolysis was achieved. Group A associated a significant reduction in lysis duration and UK dosage and hospital days and degree of detumescence after 24 h compared with group B,and all aforementioned differences were statistically significant. Hospitalization costs in group A were more than group B. At one year follow-up, there were no significant differences between the two groups in the cumulative prevalence post-thrombotic syndrome (PTS) and the Villalta score and primary patency (92.0% vs. 90.0% , χ2=0.059, P=0.807). Conclusions:The application of PMT using the Aspirex device for acute IFDVT was safe and effective, which could accelerate the clearance of thrombus, and reduce UK dosage, lysis duration, hospital days. However, it increased the hospitalization costs.
RESUMEN
AIM: To observe the effects of single-dose of fentanyl on sedation and agitation during recovery after pediatric adenotonsillectomy day surgery during anesthesia induction. METHODS: A total of 157 children undergoing elective adenotonsillectomy, with ASA physical status I or II, aged 3-10 years were selected during January and March in 2022 in the Second Affiliated Hospital of Wenzhou Medical University. The children were divided into two groups according to random number table method: remifentanil combined with fentanyl group (group RF, n = 78) and remifentanil group (group R, n = 79). Children in group RF received a single-dose injection of 1 μg/kg of fentanyl and 2.5 μg/kg of remifentanil during induction, children in group R received an equal volume of normal saline and 2.5 μg/kg of remifentanil injection. Children in both groups were intubated after propofol induction and anesthetized with combination of sevoflurane-remifentanil. The incidence and severity of emergence agitation (EA), Ramsay sedation score and FLACC pain score in post-anesthesia care unit (PACU), extubation time, recovery time, PACU stay time, discharge time were recorded. RESULTS: Compared with group R, the incidence of EA was significantly lower (38.0% vs. 18.0%, P = 0.005), the maximum PAED score during recovery was significantly lower (7.7 ±3.3 vs. 8.9 ± 3.4, P = 0.027), and the Ramsay sedation score was significantly higher at 15 min after admission of PACU (4.4 ± 1.1 vs. 3.8 ± 1.4, P = 0.01), as well as discharge of PACU (2.0 ± 0.3 vs. 1.8 ±0.4, P = 0.03) in RF group . There was no significant difference in extubation time, recovery time, PACU stay time, discharge time, pain score (discharge of PACU and 2 h after operation) between two groups (P > 0.05). CONCLUSION: A single-dose injection of fentanyl (1 μg/kg) during anesthesia induction can increase the degree of sedation and reduce the incidence of EA in PACU after pediatric daytime adenotonsillectomy.

RESUMEN
Objective:To explore the clinical value of "hydration therapy" in the treatment of severe acute paraquat poisoning (APP).Methods:A prospective historical control observation was conducted. Fifty-eight patients with severe APP admitted to Shouguang People's Hospital Affiliated to Weifang Medical College from February 2014 to June 2019 were enrolled. Twenty-six patients admitted before May 10th, 2016 were enrolled in the standard treatment group. After being admitted to intensive care unit (ICU) from the department of emergency, patients in the standard treatment group were immediately given standard treatment such as repeated gastric lavage, catharsis, adsorption of poison by activated carbon or montmorillonite powder, drug treatment and blood purification. From May 10th, 2016, 32 patients were enrolled in the intensive treatment group. On the basis of standard treatment, "hydration therapy" was carried out, that was, 0.9% NaCl and/or 5% glucose injection were used for continuous intravenous infusion throughout the day, so as to ensure that the total amount of fluid infusion per day reached 200 mL/kg within 48-72 hours after ICU admission. At the same time, furosemide was used to strengthen diuresis to ensure the balance of water and electrolyte. If heart failure or acute pulmonary interstitial edema occurred during the treatment, "hydration therapy" should be stopped immediately. Six months after treatment, all patients were followed up. The patients with normal activity, no complaints of discomfort and no damage of heart, lung, liver, kidney and other organs were regarded as cured. The therapeutic effect of "hydration therapy" was evaluated.Results:There was no significant difference in gender, age, dosage or time from taking poison to ICU between the two groups. In the intensive treatment group, 32 patients did not appear heart failure during continuous rehydration treatment. Follow-up after 6 months showed that the overall cure rate in the intensive treatment group was significantly higher than that in the standard treatment group [59.4% (19/32) vs. 19.2% (5/26), P < 0.05]. In the 6-month follow-up, there was no significant difference in age or time from taking poison to ICU between the two groups, but the dosage in the intensive treatment group was significantly higher than that in the standard treatment group (mL: 54.06±26.03 vs. 23.00±4.47, P < 0.05). After 6 months of follow-up, chest CT showed that the lesions of pulmonary fibrosis of cured patients in both group gradually reduced with time, not completely progressive and irreversible. Conclusion:"Hydration therapy" with intensive diuresis can significantly improve the rescue success rate of patients with severe APP.

RESUMEN
Objective To investigate the effect of STAT3 knockdown on the sensitivity of breast cancer cells with drug-resistant to adriamycin (MCF-7/ADR). Methods Levels of STAT3 and p-STAT3 in MCF-7/ADR and MCF-7 cells were detected by Western Blot. The MCF-7/ADR cells were infected with lentivirus expressing STAT3-shRNA and the negative control vectors in the STAT3-RNAi group and NC group, respectively, wihle the cells in the blank group received no treatment. The transfection efficiency was observed with fluorescence microscope, the mRNA level of STAT3, protein levels of STAT3 and p-STAT3 were detected by qRT-PCR and Western Blot, respectively. MCF-7/ADR cells were treated with different concentrations of adriamycin for 48 hours, cell proliferation was detected by MTT assay and cell apoptosis was detected by flow cytometry. Results Levels of STAT3 and p-STAT3 in MCF-7/ADR cells were significantly higher than those in the MCF-7 cells (P < 0.05). The levels of STAT3 mRNA, STAT3 and p-STAT3 in the STAT3-RNAi group were significantly lower than those in the Con group and the NC group (P<0.05, respectively). The Adriamycin IC50 in the Con group, NC group and STAT3-RNAi group was (56.1 ± 3.00)ug/mL,(54.9 ± 11.9)ug/mL and (7.6 ± 0.2)ug/mL, respectively. The flow cytometry results showed that the cell apoptosis in the Con group, the NC group and the STAT3-RNAi group was (10.5+0.7)%, (11.7+0.7)%and (34+3.1)%, respectively. Conclusion LV-shRNA-STAT3 can significantly inhibit STAT3 expression and enhance the sensitivity of breast cancer cells to adriamycin, and the underlying mechanism may be related to cell apoptosis.
RESUMEN
Objective To compare surgical hybrid procedures (open thromboembolectomy/bypass,transluminal angioplasty/stenting) and endovascular hybrid procedures (percutaneous mechanical thrombectomy,catheter-directed intra-arterial thrombolysis,transluminal angioplasty/stenting) in patients with acute lower limb ischemia.Methods From June 2011 to June 2012,the clinical data and the six month follow-up data of patients with acute (less than 14 days) lower limb ischemia were collected and analyzed,who have underwent the endovascular modality hybrid procedures (endovascular modality group)or surgery modality of hybrid procedures (surgery modality group).The combined incidence of perioperative (30 days) death (POD) and major adverse limb event (MALE,include amputation or major intervention again) was defined as the primary end-point,and the secondary efficacy end-point was major adverse cardiovascular event (MACE) consisted of myocardial infarction,stroke and death from any cause.Results There were 105 and 95 cases respectively in the endovascular modality group and the surgery modality group.96 patients (99.0％) in the surgery modality group and 97 patients (92.4％) in the endovascular modality group were successfully completed with vascular reconstruction.The incidence of the primary end-point (combined POD and MALE) in the surgery modality group (7.2％) was significantly less than the endovascular modality group (17.1％).Hemorrhagic complications occurred more in the endovascular modality group (6.7％) than the surgery modality group (0％).The surgery modality group had more postoperative pulmonary complications (9.3％) than the endovascular modality group (1.0％).Conclusions Surgical hybrid procedures offer better immediate and mid-term results for patients with acute lower limb ischemia.
