RESUMO
ObjectiveTo evaluate the efficacy and influencing factors of Biejiajianwan in the treatment of primary liver cancer based on real-world data of traditional Chinese medicine （TCM）. MethodClinical diagnosis and treatment data of patients with primary liver cancer admitted to five Grade-A tertiary hospitals in Henan Province from January 2015 to December 2020 were collected from the medical electronic database. The patients treated with Biejiajianwan for ≥30 days were assigned to the exposure group and those without treatment with Biejiajianwan or treated with Biejiajianwan for <30 days to the non-exposure group. The propensity score matching model was used to balance confounding factors between the two groups according to the 1∶1 genetic matching method. Kaplan-Meier method was used for survival analysis and survival curve plotting. Log-rank was used to test the difference in survival rate between the two groups. Univariate analysis of Biejiajianwan in the treatment of primary liver cancer was performed by Log-rank test combined with the Kaplan-Meier method. The factors with statistical significance （P<0.05） were combined with unbalanced factors by the propensity score matching model， and at the same time， clinical common sense and relevant prognostic factors by literature search were considered， which were subjected to multivariate analysis by Cox proportional hazards regression model. ResultA total of 2 207 electronic cases were collected，including 174 cases in the exposure group （Biejiajianwan group） and 2 033 cases in the non-exposure group. After propensity score matching， there were 174 cases in the exposure group and 174 cases in the non-exposure group. The Kaplan-Meier method was used for survival analysis on the matched data， and the Log-rank test results showed that the survival rate of patients with primary liver cancer in the Biejiajianwan group was higher than that in the control group （χ2=12.193， P<0.01）. Cox proportional hazards regression model analysis showed that the regression coefficient of Biejiajianwan was -0.916 4 with the hazard ratio （HR） ［95% confidence interval （CI）］=0.4 （0.239 5-0.668 0）， P<0.01， and the regression coefficient of radiofrequency ablation treatment was -0.976 5 with HR （95% CI）=0.376 6 （0.172 8-0.821 1， P<0.05）. Fibrinogen （FIB） abnormal regression coefficient was 0.481 4 with HR （95% CI）=1.618 4（1.022 0-2.562 9），P<0.05. ConclusionBiejiajianwan can prolong the survival period of patients with primary liver cancer. Radiofrequency ablation is an independent protective factor for Biejiajianwan in the treatment of primary liver cancer，while abnormal FIB are independent risk factors for Biejiajianwan in the treatment of primary liver cancer.
RESUMO
During the COVID-19 epidemic, our national guidelines have suggested that surgical patients should wear a mask to decrease the potential transmission of COVID-19 in the operating room, as long as the condition allows. However, so far, there is no study to discuss the influence of wearing a mask on the ventilation and blood oxygenation status in patients of spontaneous breathing with supplementary oxygen through an anesthetic facemask. This is a before-after study in the same patient, and 10 healthy volunteers were recruited, by testing the arterial blood gas parameters at key time points before and after oxygen inhalation to evaluate the effects of two different supplementary oxygen methods ('disposable medical mask + anesthetic facemask' and 'anesthetic facemask only') on the oxygenation of subjects. Our data demonstrated whether wearing a disposable medical mask or not could effectively increase the oxygen supply of the subjects compared with the basic value before oxygen inhalation; however, compared with the group without mask, the arterial oxygen partial (PaO

Objective To explore the effects and feasibility of minimal local analgesic dose of hyperbaric levobupivacaine in elderly patients undergoing unilateral spinal anesthesia during lower limb orthopedic surgery.Methods Seven hundred and fifty-six elderly patients who scheduled lower limb orthopedic surgery were assigned to levobupivacaine group (383 patients) and bupivacaine group (373 patients) by random digits table method.Haemodynamic change were monitored before,during and after anesthesia.The level and duration of sensory and motor block in each group were evaluated.Results Compared with bupivacaine group,the sensory block and motor block onset time was significantly longer in levobupivacaine group [(5.9 ± 1.4) min vs.(4.2 ± 0.3) min,(11.7 ± 3.0) min vs.(9.1 ± 3.3) min] (P ＜0.05),but the motor block duration was shorter [(152.8 ± 17.5) min vs.(195.4 ± 18.7) min] (P ＜ 0.05).The scores of maximum motor block in levobupivacaine group was significantly lower than that in bupivacaine group[(1.1 ±0.3) min vs.(2.3 ±0.6) min](P＜ 0.05).There was no significant difference in peak sensory block and haemodynamic between two groups (P ＞ 0.05).Conclusions Although levobupivacaine may be less potent than bupivacaine,it may be preferred for elderly patients with lower limb surgery because of satisfactory spinal anesthesia,good hsemodynamic stability and fast motor block regression.
RESUMO
Objective To evaluate the effects of intravenous analgesia with dezocine combining sufentanil in hip and knee arthroplasty for elderly patients.Methods Ninety patients with ASA Ⅱ ～ Ⅲ and aged ≥ 65 years who were scheduled for hip and knee arthroplasty under CSEA and treated with intravenous analgesia post-operation were selected and divided into three group (20 cases):group Ⅰ (sufentanil 2.5μg/kg + droperidol 2.5 mg),group Ⅱ (sufentanil 2.0 μ g/kg + dezocine 10 mg + droperidol 2.5 mg) and group Ⅲ (intramuscular dezocine 10 mg and sufentanil 2.0 μ g/kg + droperidol 2.5 mg),which were diluted to be 100 ml by adding saline.VSA,Ramsay score as well as side effects were recorded at 6,12 and 24 h after operation.75 mg meperidine was administered intramuscularly as rescue medication when VAS was above 5.Results Compared with group Ⅰ and Ⅲ,group Ⅱ showed better outcomes regarding to the VAS and less side effects.Ramsay score 6 h after operation and the amount of patients who needed meperidine in group Ⅲ were higher than those in the other two groups (P ＜ 0.05).Conclusion Dezocine combining with sufentanil in elderly patients underwent low limb arthroplasty shows better postoperative analgesia effects with less side effects,and it's worth for clinical application.
RESUMO
BACKGROUND: Orotracheal intubation with conventional Macintosh laryngoscope often makes strong alterations in hemodynamic responses. Compare with the Macintosh laryngoscope, the Airtraq~((R)) laryngoscope has weak effect on throat irritation. However, the contrast effect on hemodynamics remains still unknown. OBJECTIVE: To compare the hemodynamical responses to orotracheal intubation between Airtraq~((R)) laryngoscope and Macintosh laryngoscope. DESIGN, TIME AND SETTING: A randomized comparative observation was performed at Department of Anesthesiology, Dalian Second People's Hospital between October 2008 and April 2009. PARTICIPANTS: A total of 40 patents scheduled for surgery under general anesthesia requiring orotracheal intubation were randomly divided into Airtraq~((R)) laryngoscope group and Macintosh laryngoscope group, with 20 cases in each group. METHODS: After standard intravenous anesthetic induction, orotracheal intubation was performed with Airtraq~((R)) laryngoscope or Macintosh laryngoscope. Common Airtraq~((R)) laryngoscope was used in the Airtraq~((R)) laryngoscope group, and an endotracheal tube with internal diameter of 8.0 was inserted. No. 3 lens were used in the Macintosh laryngoscope group, and an endotracheal tube with internal diameter of 8.0 was inserted. MAIN OUTCOME MEASURES: Glottic exposure time, tracheal intubation time, noninvasive heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) before (T0) and after (T1) anesthetic induction as well as at 0 minute (T2), 1 minute (T3), 2 minutes (T4), and 3 minutes (T5) after intubation, as well as rate-pressure product (RPP). RESULTS: The glottic exposure time in Airtraq~((R)) laryngoscope group was significantly longer than that in Macintosh laryngoscope group (P < 0.01), while the tracheal intubation time in Airtraq~((R)) laryngoscope group was significantly shorter than that in Macintosh laryngoscope group (P < 0.01). Compared with pre-induction (T0), the SBP, DBP, and RPP of the two groups decreased significantly after anesthetic induction (T1) (P < 0.05), but the HR did not change remarkably (P > 0.05). Compared with T1, all hemodynamical values at T2, T3, T4 and T5 in Airtraq~((R)) laryngoscope group did not increased sign ificantly (P > 0.05). In Macintosh laryngoscope group, HR and RPP at T4, SBP, DBP, HR and RPP at T2 and T3 increased significantly compared with T1 (P < 0.05). In Macintosh laryngoscope group, HR and RPP at T2, T3 and T4 were significant higher than that in Airtraq~((R)) laryngoscope group (P< 0.05). CONCLUSION: In comparison to the Macintosh laryngoscope, tracheal intubation with the Airtraq~((R)) laryngoscope resulted in less alterations in hemodynamical responses.
