Objective. To explore the application of different doses of dexmedetomidine combined with general anesthesia in patients with traumatic tibiofibular fractures. Methods. A total of 120 patients with traumatic tibiofibular fractures treated in our hospital (January 2018–January 2021) were selected as the research subjects and equally grouped into group A, group B, group C, and group D according to the dosage of dexmedetomidine. Group B, group C, and group D were pumped with 0.3 μg/kg, 0.5 μg/kg, and 0.8 μg/kg load doses of dexmedetomidine before anesthesia induction, with the same doses for maintenance during surgery. Group A was intravenously pumped with the same amount of normal saline and received tracheal intubation after anesthesia induction, with propofol and remifentanil to maintain general anesthesia during surgery. Results. No notable differences in general data were observed among the groups ( P  > 0.05). Ramsay sedation scores of all groups showed a downward trend after drug withdrawal. At 10 min, 30 min, and 60 min, the scores of groups C and D were markedly higher than those of groups A and B ( P  < 0.05), and the scores were higher in group D than those in group C ( P  < 0.05). The HR changes at each period were close between groups A and B ( P  > 0.05). The HRs at T1 and T2 in group C were slightly lower than those in group D ( P  > 0.05), and the HRs at T1 in groups A and B were remarkably higher than those in groups C and D, and were higher than those at T0 and T2 ( P  < 0.05). The SBP levels of all groups began to rise at T0, peaked at T1, and decreased to a lower level at T2 than that at T0. Moreover, the SBP levels of groups C and D at T1 and T2 were notably lower compared with groups A and B ( P  < 0.05). With a lower DBP level in group C than the other three groups at T1, the DBP levels were notably lower in groups C and D than those in groups A and B at T2 ( P  < 0.05). With no statistical difference in the MAP levels at T0 among the four groups ( P  > 0.05), the MAP levels in group A at T1 and T2 were obviously higher compared with groups C and D ( P  < 0.05). The extubation time in group A was notably longer than that that in groups B, C, and D ( P  < 0.05), with longer extubation time in group B than that in groups C and D ( P  < 0.05). The orientation recovery time in group D was markedly shorter than that in groups A, B, and C ( P  < 0.05). The incidence of cognitive dysfunction, chills, and restlessness in groups C and D was notably lower compared with groups A and B ( P  < 0.05), with a higher incidence of chills, intraoperative hypotension, and delayed awakening in group D than in group C ( P  < 0.05). Conclusion. Dexmedetomidine at doses of 0.5 μg/kg and 0.8 μg/kg has a better effect in the maintenance of general anesthesia for patients with traumatic tibiofibular fractures, with faster orientation recovery, better recovery of postoperative cognitive function, and a lower incidence of adverse reactions. Dexmedetomidine at 0.5 μg/kg is recommended in view of the increased risk of excessive sedation, chills, restlessness, and intraoperative hypotension in patients at 0.8 μg/kg.

Abstract Background: To compare the efficacy and safety of different compatibility schemes in the prevention of visceral pain after gynecological laparoscopic surgery. Methods: from April 2019 to April 2020, patients undergoing elective gynecological laparoscopic surgery in our hospital were randomly divided into four groups: group A: sufentanil 3 μ g / kg; group B: low-dose nalbuphine group: 0.1 mg / kg of nabufen + 3 μ g / kg of sufentanil; group C: medium dose of nabufen group: 1 mg / kg of nabufen + 2 μ g / kg of sufentanil; group D: high-dose nabufen 2 There were 30 cases in each group. The degree of pain and the number of adverse reactions at 2, 4, 8, 12, 24 and 48 hours after operation were observed and recorded. The number and dosage of morphine used as a remedial analgesic were recorded. The pain degree was assessed by visual analogue scale (VAS). The total amount of analgesic pump used, the total number of times of pressing and the effective times of pressing were recorded. The adverse reactions included respiratory depression, nausea and vomiting, drowsiness, restlessness and skin The skin itches. Results: the analgesic effect of group B was similar to that of group A, and there was no significant difference in the number of invalid pressing, total pressing times and rescue analgesia rate (P > 0.05), while the invalid pressing times, total pressing times and remedial analgesia rate of group C and group D were significantly lower than those of group A (P < 0.05). There was no significant difference between group C and group D in the number of invalid compressions, the total number of compressions and the rate of remedial analgesia (P > 0.05), suggesting that increasing the dose of nalbuphine could not significantly increase the analgesic effect. The incidence of postoperative nausea and vomiting, skin pruritus, lethargy and Ramsay Sedation score in group B and group C were significantly lower than those in group A (P < 0.05). Ramsay Sedation score and incidence of drowsiness were lower than those in group D, which indicated that the incidence of adverse reactions was higher in group D than group B and group C.Conclusion: the combination of 1 mg / kg nabufen and 2 μ g / kg sufentanil is a safe and effective combination scheme for the prevention of visceral pain after gynecological laparoscopic surgery with small adverse reactions.Trial registration: http://www.chictr.org.cn/showproj.aspx?proj=40635Registration number:ChiCTR1900025076 .

Abstract Background: Palliative care is becoming more and more important for systemic cancer treatment in developed countries, while this remains infamous topic in developing countries, such as in China. Contemporary treatment strategies have greatly contributed to the improved outcome in childhood cancer patients, survivorship comes at the cost of developing some treatment-related health condition, such as pain-related depression, chronic pain etc. Thus, developing a well-tolerated pain control methods is of great importance within the cancer treatment. Objective: To evaluate the impact and outcome of different pain control applications on invasive procedure in children with leukemia, and record the adverse reactions. Methods: The enrollment of childhood leukemia patients in our hospital from November 2011 to November 2016 were divided into four groups, that is successively midazolam + local anesthesia (group A), midazolam + ketamine +local anesthesia (group B), midazolam + fentanyl + local anesthesia (group C), and fentanyl + propofol + local anesthesia (group D). The efficacy and adverse reactions were systemically recorded. The inter-group diffferences were calculated using x2 test. Results: No significancewas observed in age, gender, and disease distribution in these four groups by ANOVA ONEWAY analysis. The sedation outcome is more pronunced in group D than others. Also, the quality of procedural pain control in group D was the best (P<0.01). In terms of the analgesic effect, group B and D were better than that group A and C. There was significant difference in Hallucination was more easily detected in group B and C. Systemic recovery was delayed in group B other than group A, C, and D. Basing on the survey, we did found that the family members were more willing to accept pain control treatment for their sick kids under the safety assurance. The compliance was significantly improved in group D. Conclusion: Upon adequate auxiliary breathing preparation and rigorous monitor, propofol combined with low-dose fentanyl was the best sedative/analgesic option for pain control within leukemia patients receiving invasive procedure.The outcome of propofol combined with low-dose fentanyl wasvery safe, satisfactory and compliable. Up to now, this study is the first pain control study for invasive procedure in China mainland, it deserves being paid attention. Disclosures No relevant conflicts of interest to declare.

Abstract Background This study aimed to investigate the anesthetic effect of butorphanol with different doses in patients undergoing gastroscopy and colonoscopy. Methods 480 patients undergoing gastroscopy and colonoscopy were recruited and randomly divided into four groups to receive different doses of butorphanol (Group A = 2.5 μg/kg, Group B = 5 μg/kg, Group C = 7.5 μg/kg and Group D = 10 μg/kg). Butorphanol was administered 5 min before propofol infusion. The primary outcome was the incidence of body movement. Secondary outcomes were postoperative recovery time, length of stay in the Post-Anesthesia Care Unit (PACU), the total dose of propofol, and the incidence of intraoperative hypoxemia, propofol injection pain, cough, postoperative nausea and vomiting, drowsiness, and dizziness. Results The incidence of body movement and the dose of propofol in Group C and D were lower than those in Group A and B (P < 0.05). The incidence and intensity of propofol injection pain and the incidence of cough in Group B, C, and D were lower than those in Group A (P < 0.05). The length of stay in PACU and the incidence of postoperative drowsiness and dizziness were higher in Group D than in Group A, B, and C (P < 0.05). Conclusion Intravenous pre-injection of 7.5 μg/kg butorphanol with propofol can be the optimal dosage for patients undergoing gastroscopy and colonoscopy.

Summary Objective: The effects of various parturition controlling measures in sows on the relevant parameters for parturition were investigated. Material and methods: A total of 1975 study animals were divided into five groups: control group: A (n = 710); trial groups: B (n = 719), C (n = 180), D (n = 175), E (n = 191). The control group (A) included sows that spontaneously farrowed until day 114 of gestation. The remaining sows were administered a PGF2α-analogue (175 µg cloprostenol) on day 114. All sows that farrowed within 24 hours after prostaglandin-medication were summarised in trial group B. Dams that did not farrow until day 115 were either administered oxytocin (20 IU i. m., group C) or carbetocin in two different doses (70 µg, group D or 35 µg, group E). The sows were monitored during the peripartal period over 24 hours. Results: 83.8% of the farrowings were without any complications. The percentage of dystocia varied between the individual groups. Given a complication-free farrowing the expulsion stage began 13.0 hours (group B), 2.4 hours (group C), 1.6 hours (group D) and 1.4 hours (group E) after medication. The expulsion interval of the farrowing of two piglets decreased from 21.1 minutes with spontaneous farrowings (group A) to 18.6 minutes (group E) as a result of the administration of 35 µg carbetocin. The rate of stillborn piglets as well as the incidence of puerperal disorders and the losses of the suckling piglets also gradually, partly even significantly (p 0.05) decreased from group A to E. Conclusion and clinical relevance: The results of this study show that the use of the long-acting oxytocin carbetocin has advantages compared to oxytocin (e. g. shortened duration of birth, reduction of stillbirths). The tested dosages of carbetocin (35 µg or 70 µg) proved to be equally effective. Administration of the lower dose is recommended, since this reduces use of the active ingredient.

The study was to determine the presence of Classical Swine Fever virus (CSFv), in the meat of vaccinated pigs with the PAV-250 strain and then challenged using the same strain. Five treatment groups were established (each with four pigs). Group A: Pigs thatwere fed with processed hams from negative animals; Group B: Pigs that were fed with processed hams from commercial pigs inoculated with the ALD (reference strain) (titre of 104.0/ml); Group C: Pigs fed with processed hams from pigs infected with the virulent ALD strain (titre of 102.5/ml); Group D: Pigs fed with processed hams from pigs vaccinated with the PAV-250 strain and challenged with the ALD strain (titre of 101.1/ml); and Group E: Pigs fed with processed hams from pigs vaccinated with two doses of the PAV-250 strain and challenged with the ALD strain (negative). Blood samples were taken at d 1, 5, 10, 15 and 20 for biometric analysis. Groups B, C and D manifested clinical signs of CSFv: 40 °C temperature, anorexia, paralysis, vomiting, diarrhea, tremor, hirsute hair and cyanosis. Pigs were slaughtered and necropsies performed to identify lesions in tissues. Results of direct immunofluorescence testing of tissues were positive and the virus was recovered. Under these study conditions, it was found that CSFv resisted the cooking method at 68 °C for 40 min in hams from unvaccinated pigs, and that the virus was able to transmit the disease to healthy unvaccinated pigs, whereas the hams from the vaccinated animals did not transmit the virus.

Objective: To study the effectiveness of prophylactic ephedrine to prevent hypotension caused by induction of anesthesia with propofol and sufentanil in elderly hypertensive patients. Methodology: 70 elderly ASA grade II-III hypertensive patients undergoing elective general anesthesia were randomized into two groups to receive either intravenous ephedrine,100 ug/kg in 5ml normal saline (Group B), or an equal volume of normal saline (Group A) before induction. Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR) were recorded at T0 (after entry to the operating room), T1 (1 min after induction), T2 (2 min after induction), T3 ( 3 min after induction), T4 (4 min after induction), T5 (when intubated), T6 (2 min after intubation), and T7 (at the start of the procedure), as well as the incidence of hypotension and bradycardia. Results: SBP, DBP and HR were not significantly different at T0 and were significantly different at T1 to T7 after anesthesia induction. There were statistically significant effect on hypotension and bradycardia between the two groups and group B have a lower risk of hypotension and bradycardia relative to group A. SBP and DBP decreased significantly after induction in both groups. HR decreased significantly in group A while increased in group B. Conclusion: Ephedrine pretreatment can minimize hypotension and bradycardia caused by propofol and sufentanil during the induction of general anesthesia in elderly patients with hypertension.

<b><i>Introduction:</i></b> The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. <b><i>Methods:</i></b> We included the patients &#x3e;18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight &#x3c;25 kg/m<sup>2</sup> (Group A), overweight from 25 to &#x3c;30 kg/m<sup>2</sup> (Group B), Class I obesity 30 to &#x3c;35 kg/m<sup>2</sup> (Group C), and ≥35 kg/m<sup>2</sup> (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. <b><i>Results:</i></b> There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [<i>p</i> = 0.017], Group D vs. Group A [<i>p</i> = 0.001], and Group D vs. Group C [<i>p</i> = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [<i>p</i> = 0.025], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> = 0.006], and Group D vs. Group C [<i>p</i> = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [<i>p</i> &#x3c; 0.001], Group C vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> &#x3c; 0.001], and Group D vs. Group C [<i>p</i> = 0.010]). <b><i>Conclusion:</i></b> COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications.

AbstractEndovascular treatment (EVT) has been accepted as the standard of care for patients with acute ischemic stroke. The aim of the present study was to compare clinical outcomes of patients who received EVT within and beyond 6 h from symptom onset to groin puncture without perfusion software in Guangdong district, China. Between March 2017 and May 2018, acute ischemic stroke patients who received EVT from 6 comprehensive stroke centers, were enrolled into the registry study. In this subgroup study, we included all patients who had acute proximal large vessel occlusion in the anterior circulation. The demographic, clinical and neuroimaging data were collected from each center. A total of 192 patients were included in this subgroup study. They were divided into two groups: group A (n = 125), within 6 h; group B (n = 67), 6–24 h from symptom onset to groin puncture. There were no substantial differences between these two groups in terms of 90 days favorable outcome (modified Rankin scale [mRS] ≤ 2, P = 0.051) and mortality (P = 0.083), and the risk of symptomatic intracranial hemorrhage at 24 h (P = 0.425). The NIHSS (median 16, IQR12-20, group A; median 12, IQR8-18, group B; P = 0.009) and ASPECTS (median 10, IQR8-10, group A; median 9, IQR8-10, group B; P = 0.034) at baseline were higher in group A. The anesthesia method (general anesthesia, 21.3%, group A vs. 1.5% group B, P = 0.001) were also statistically different between the two groups. The NIHSS and ASPECTS were higher, and general anesthesia was also more widely used in group A. Clinical outcomes were not significantly different within 6 h versus 6–24 h from symptom onset to groin puncture in this real world study.

Background:Cardiovascular disease (CVD) is detected in up to 50% of systemic lupus erythematosus (SLE) patients1and major cause of death2. Even clinically silent SLE patients can develop left ventricular (LV) diastolic dysfunction3. Proper echocardiographic follow up of SLE patients is required.Objectives:To clarify how the prevalence of LV abnormalities changes over follow-up period and identify the associated clinical factors, useful in suspecting LV abnormalities.Methods:29 SLE patients (24 females and 5 men, mean age 52.8±16.3 years, mean disease duration 17.6±14.5 years) were enrolled. All of them underwent echocardiography as the baseline examination and reexamined over more than a year of follow-up period(mean 1075±480 days) from Jan 2014 to Sep 2019. Patients complicated with pulmonary artery hypertension, deep venous thrombosis or pulmonary embolism and underwent cardiac surgery during the follow-up period were excluded. Left ventricular(LV) systolic dysfunction was defined as ejection fraction (EF) < 50%. LV diastolic dysfunction was defined according to ASE/EACVI guideline4. LV dysfunction (LVD) includes one or both of LV systolic dysfunction and LV diastolic function. Monocyte to HDL ratio (MHR) was calculated by dividing monocyte count with HDL-C level.Prevalence of left ventricular abnormalities was analysed at baseline and follow-up examination. Clinical characteristics and laboratory data were compared among patient groups as follows; patients with LV dysfunction (Group A) and without LV dysfunction (Group B) at the follow-up echocardiography, patients with LV asynergy at any point of examination (Group C) and patients free of LV abnormalities during the follow-up period (Group D).Results:At the baseline examination, LV dysfunction (5/29 cases, 13.8%), LV asynergy (6/29 cases, 21.7%) were detected. Pericarditis was detected in 7 patients (24.1%, LVD in 3 patients, LV asynergy in 2 patients) and 2 of them with subacute onset had progressive LV dysfunction, while 5 patients were normal in echocardiography after remission induction therapy for SLE. At the follow-up examination, LV dysfunction (9/29 cases, 31.0%, 5 new-onset and 1 improved case), LV asynergy (6/29 cases, 21.7%, 2 new-onset and 2 improved cases) were detected. Though any significant differences were observed between Group A and Group B at the baseline, platelet count (156.0 vs 207.0, p=0.049) were significantly lower in LV dysfunction group (Group A) at the follow-up examination. Group C patients had significantly higher uric acid (p=0.004), monocyte count (p=0.009), and MHR (p=0.003) than Group D(results in table).Conclusion:LV dysfunction is progressive in most of patients and requires regular follow-up once they developed. Uric acid, monocyte count and MHR are elevated in SLE patients with LV asynergy. Since MHR elevation was reported as useful marker of endothelial dysfunction5, our future goal is to analyse involvement of monocyte activation and endothelial dysfunction in LV asynergy of SLE patients.References:[1]Doria A et al.

Abstract Background Pernicious placenta previa (PPP) can increase the risk of perioperative complications. During caesarean section in patients with adherent placenta, intraoperative blood loss, hysterectomy rate and transfusion could be reduced by interventional methods. Our study aimed to investigate the influence of maternal hemodynamics control and neonatal outcomes of prophylactic temporary abdominal aortic balloon (PTAAB) occlusion for patients with pernicious placenta previa. Methods This was a retrospective study using data from the Peking University People’s Hospital from January 2014 through January 2020. Clinical records of pregnant women undergoing cesarean section were collected. Patients were divided into two groups: treatment with PTAAB placement (group A) and no balloon placement (group B). Group A was further broken down into two groups: prophylactic placement (Group C) and balloon occlusion (group D). Results Clinical records of 33 cases from 5205 pregnant women underwent cesarean section were collected. The number of groups A, B, C, and D were 17, 16, 5 and 12.We found that a significant difference in the post-operative uterine artery embolism rates between group A and group B (0% vs.31.3%, p = 0.018). There was a significant difference in the Apgar scores at first minute between group A and group B (8.94 ± 1.43 vs 9.81 ± 0.75,p = 0.037),and the same significant difference between two groups in the pre-operative central placenta previa (29.4% vs. 0%,p = 0.044), complete placenta previa (58.8% vs 18.8%, p = 0.032),placenta implantation (76.5% vs 31.3%, p = 0.015). We could also observe the significant difference in the amount of blood cell (2.80 ± 2.68vs.10.66 ± 11.97, p = 0.038) and blood plasma transfusion (280.00 ± 268.32 vs. 1033.33 ± 1098.20, p = 0.044) between group C and group D. The significant differences in the preoperative vaginal bleeding conditions (0% vs 75%, p = 0.009), the intraoperative application rates of vasopressors (0% vs. 58.3%, p = 0.044) and the postoperative ICU (intensive care unit) admission rates (0% vs. 58.3%, p = 0.044) were also kept. Conclusions PTAAB occlusion could be useful in reducing the rate of post-operative uterine artery embolism and the amount of transfusion, and be useful in coping with patients with preoperative vaginal bleeding conditions, so as to reduce the rate of intraoperative applications of vasopressors and the postoperative ICU (intensive care unit) admission. In PPP patients with placenta implantation, central placenta previa and complete placenta previa, we advocate the utilization of prophylactic temporary abdominal aortic balloon placement.
