Objective To evaluate the accuracy of respiratory variations of internal jugular vein (IJV) in monitoring fluid responsiveness in patients undergoing radical gastrectomy for gastric cancer.Methods Fifty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 40-64 yr,scheduled for elective radical gastrectomy for gastric cancer,were enrolled in this study.Before induction of anesthesia,the hemodynamic parameters such as heart rate,central venous pressure,cardiac index,stroke volume index (SVI),stroke volume variation and respiratory variation of IJV were recorded after haemodynamics was stable and were recorded again at 10 min after endotracheal intubation,and a loading dose of 6％ 130/0.4 hydroxyethyl starch 7 ml/kg was infused over 15 min.The parameters mentioned above were recorded within 5 min after loading dose.Patients were divided into 2 groups according to the percentage of increase in SVI (△SVI) after volume expansion:△SVI≥ 15％ was considered to be a positive response (responder group) and △SVI＜15％ was considered to be a negative response after volume expansion (non-responder group).Results The area under the receiver operating characteristic curve of respiratory variations of IJV in monitoring fluid responsiveness and 95％ confidence interval were 0.852 (0.744-0.961).Respiratory variation of IJV 24.6％ was considered as the cut-off value and used to monitor fluid responsiveness,and the sensitivity and specificity were 67.6％ and 92.3％,respectively.Conclusion Respiratory variation of IJV can be considered as an effective index in monitoring fluid responsiveness in the patients undergoing radical gastrectomy for gastric cancer.

Objective To evaluate the accuracy of respirophasic variation in carotid artery blood flow peak velocity(ΔVpeak-CA)in predicting fluid responsiveness in the patients undergoing surgery in the prone position. Methods Forty-three American Society of Anesthesiologists physical status Ⅰ-Ⅲ pa-tients of both sexes, aged 45-75 yr, with body mass index of 20-25 kg∕m2, scheduled for elective posteri-or approach lumbar surgery, were enrolled in the study.After induction of anesthesia, hydroxyethyl starch 130∕0.4 sodium chloride injection 7 ml∕kg was intravenously infused over 20 min when the patients were in the prone position.Subjects were classified as responders if stroke volume index increased≥15% after vol-ume expansion.The receiver operating characteristic curve for ΔVpeak-CA in determining positive fluid re-sponsiveness was drawn. Results The results of receiver operating characteristic curve analysis showed that: the cut-off value of ΔVpeak-CA in predicting positive fluid responsiveness was 7.94%, sensitivity 81.8%, specificity 70.0%, and the area under the curve(95% confidence interval)was 0.818 (0.378-0.757). Conclusion Respirophasic ΔVpeak-CA can accurately predict fluid responsiveness in the patients undergoing surgery in the prone position.

Objective To analyze the safety and efficacy of neuroendoscopic minimally invasive surgery and traditional extraventricular drainage in the treatment of severe hypertensive intraventricular hemorrhage.Methods The clinical data of 50 cases with neuroendoscopic ventricular hematoma evacuation(endoscopy group)and 44 cases with traditional ventricles external puncture drainage(drainage group)from July 2020 to July 2023 were retrospectively analyzed,and the hematoma clearance rates,classification of activities of daily living(ADL)scale,incidence of hydrocephalus,secondary bleeding,intracranial infection,and pulmonary infection were observed between the two groups of patients.Results After surgery,the proportion of patients with hematoma clearance rate>60％and ADL grades Ⅰ,Ⅱ,and Ⅲ in the endoscopy group were significantly higher than those in the drainage group[the proportion of patients with hematoma clearance rate>60％:88.0％(44/50)vs.47.7％(21/44),χ2=17.794,P<0.001;the proportion of individuals with ADL grades Ⅰ,Ⅱ,and Ⅲ:94.0％(47/50)vs.77.3％(33/44),respectively,χ2=5.459,P=0.019],the incidence of complications in endoscopy group was significantly lower in the drainage group[8.0％(4/50)vs.34.1％(15/44),χ2=9.879,P=0.002].Conclusion Compared with traditional ventricular puncture drainage surgery,neuroendoscopic minimally invasive surgery for the treatment of severe hypertensive intracerebral hemorrhage with ventricular casting can achieve better treatment outcomes,a higher hematoma clearance rate,and fewer postoperative complications.

Objective To study the characteristics of fluid intake and central venous pressure (CVP) within 4 days after birth in very low birth weight (VLBW) premature infants complicated with bronchopulmonary dysplasia (BPD).Method From February 2015 to March 2019,VLBW preterm infants without serious complications were enrolled in two hospitals.Their CVP were measured every 4 ～ 6 hours after birth.They were assigned into BPD group and non-BPD group,and the fluid intake and CVP within 4 days after birth were compared between these two groups.Result A total of 45 VLBW preterm infants were included,including 17 in the BPD group and 28 in the non-BPD group.The fluid intake in the BPD group showed no significant difference with the non-BPD group within 4 days after birth (P ＞ 0.05).No significant correlation existed between the mean liquid intake and the mean CVP in 1 ～ 4 days after birth (r =0.093,P=0.542).From day1 to day4,the CVPs of the BPD group were (3.97 ± 0.68),(4.49 ± 0.75),(4.55 ± 0.66),(4.02 ± 1.05) cmH2O,and the non-BPD group were (3.66 ± 1.09),(3.96 ±0.76),(3.81 ± 0.69),(3.91 ± 0.65) cmH2O.The differences between the BPD group and the nonBPD group were statistically significant (P ＜ 0.05).The CVP of the BPD group was increasing from day 2 to day 3 (P ＜ 0.05).Conclusion VLBW premature infants complicated with BPD may have higher CVP at the early stage of life,which may not be related with the fluid intake.
