Objective:To investigate the effect of dexmedetomidine (DEX) on reducing urethral stimulation in patients undergoing laparoscopic gastrointestinal surgery.Methods:From January 2019 to February 2020, 90 patients undergoing elective laparoscopic gastrointestinal surgery under general anesthesia in the Third Affiliated Hospital of Sun Yat-sen University were selected. They were randomly divided into 3 groups: catheterization before induction (group A), catheterization during induction (group B), and catheterization after induction (group C). In group A, patients received general anesthesia after awake catheterization. In group B, intravenous injection of DEX 0.5 μg/kg was pumped for 10 minutes, followed by catheterization and induction. In group C, patients received general anesthesia and then catheterization. Visual analogue scale (VAS) score of urethral stimulation, morphine dosage and the incidence of agitation during resuscitation were recorded. The heart rate and mean arterial pressure of the three groups were compared at the time of entering the room, catheterization, tracheal intubation, entering postanesthesia care unit (PACU), about extubation and 30 minutes after extubation.Results:The fluctuation of blood pressure and heart rate in group B was significantly less than that in group A and group C at the time of extubation and 30 minutes after extubation ( P<0.05). VAS of urethral stimulation in group B [(2.9±0.9)point] was significantly lower than that in group A [(4.4±1.8)point] when catheter was indwelling ( P<0.05). After extubation, VAS in group B [(2.8±1.1)point] was significantly lower than that in group A [(3.2±1.2)point] and C [(5.2±1.8)point] ( P<0.05). The utilization rate of morphine within 24 hours after surgery in group B (10%) was significantly lower than that in the other two groups (40%, 57%), and the incidence of postoperative agitation in group A and B was lower than that in group C within PACU ( P<0.05). The satisfaction of patients in group B (86.7%) was higher than that in group A (70%) and C (46.7%). The satisfaction of PACU personnel in group A (76.7%) and B (80%) was significantly higher than that in group C (43.3%). Conclusions:Sedation with dexmedetomidine during urethral catheterization can reduce urethral stimulation during resuscitation and improve patients' and PACU staffs' satisfaction.

Objective:To evaluate the effect of controlled low central venous pressure with milrinone on laparoscopic hepatectomy in the patients.Methods:Fifty American Society of Anesthesiologists physical statusⅠ-Ⅲ patients of both sexes, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of Child-Pugh grade A or B, undergoing elective laparoscopic hepatectomy, were divided into 2 groups ( n=25 each) using a random number table method: milrinone group (group M) and nitroglycerin group (group NG). After the start of surgery, milrinone 0.5 μg·kg -1·min -1 was continuously infused in group M, and nitroglycerin was continuously infused with the initial dose of 0.5 μg·kg -1·min -1 to maintain central venous pressure (CVP)≤5 mmHg in group NG.Mean arterial pressure and heart rate were recorded on admission to the operation room (T 0), at skin incision (T 1), at the beginning of liver resection (T 2), at completion of liver resection (T 3), at the end of operation (T 4), and CVP, cardiac index and stroke volume variation were recorded at T 1-4.Internal jugular vein blood samples were collected to determine the concentrations of hemogloblin, blood lactate at T 1 and T 4, and serum alanine aminotransferase, aspartate aminotransferase and creatinine concentrations at 1, 3 and 7 days after surgery.The score of blood oozing in hepatic surgical field, amount of norepinephrine used, blood loss, postoperative recovery and occurrence of complications within 7 days after operation were recorded. Results:Compared with group NG, cardiac index was significantly increased at T 2, 3, the CVP was decreased at T 2, the blood oozing score, blood loss, consumption of norepinephrine, and concentrations of blood lactate were decreased, and the postoperative drainage indwelling time was shortened in group M ( P<0.05). There was no significant difference in the serum alanine aminotransferase, aspartate aminotransferase and creatinine concentrations and incidence of postoperative complications at 1, 3 and 7 days after operation between the two groups ( P>0.05). Conclusions:Milrinone is better than nitroglycerin in decreasing central venous pressure, reducing blood loss, maintaining stable circulatory function and tissue perfusion in laparoscopic hepatectomy.

OBJECTIVES:
To investigate the clinical characteristics and risk factors for severe events of coronavirus disease 2019 (COVID-19) in elderly patients.
METHODS:
Retrospective analysis was performed on the clinical data of all elderly COVID- 19 patients treated in Changsha Public Health Treatment Center from January 17, 2020 to March 15, 2020, which included basic diseases, symptoms, test results, and other clinical characteristics, and prognostic indicators such as severity of illness, length of hospital stay, virus shedding time and mortality rate. The differences in clinical characteristics and prognostic indicators between elderly, middle-aged, and young COVID-19 patients were also analyzed. Logistic regression model was used to conduct univariate and multivariate analysis of risk factors for developing severe events in elderly COVID-19 patients; receiver operating characteristic (ROC) curve analysis was used to evaluate the prediction efficacy.
RESULTS:
Of the 230 COVID-19 adult patients, 34 were young patients (14.8%), 136 were middle-aged patients (59.1%), and 60 were elderly (26.1%). Among the 60 elderly patients, 23 were male (38.3%) and 37 were female (61.7%), with a medium age of 66 years old. Common symptoms were fever (66.7%), cough (50.0%), and fatigue (41.7%). C reactive protein (CRP) was increased significantly. The proportion of severe cases was 31.7%, and mortality was 1.7%. The median length of hospitalization and median virus shedding time were 18.5 days and 21 days, respectively. Compared with the young and the middle-aged patients, the elderly had a higher proportion of hypertension, diabetes, and cardiovascular diseases, more common shortness of breath, higher proportions of pneumonia and severe cases (all <0.05), and the decreased lymphocyte count and lymphocyte percentage (both <0.05), as well as higher CRP and erythrocyte sedimentation rate (ESR) levels (both <0.05). Compared with non-severe cases, severe elderly patients demonstrated higher CRP and aspartate aminotransferase (AST) levels (all <0.05), the reduced lymphocyte count (<0.05), and the prolonged length of hospitalization and virus shedding duration (both <0.05). Univariate logistic regression analysis indicated that the lymphocytes proportion, CRP and AST levels were significantly correlated with the risk for developing severe events in elderly COVID-19 patients (all <0.05). Multivariate logistic regression found that severe events in elderly patients with COVID-19 were significantly correlated with CRP level (OR=1.041, =0.013). ROC curve analysis revealed that the area under the curve (AUC) for CRP to diagnose severe events in elderly COVID 19 patients was 0.851.
CONCLUSIONS
The proportion of severe cases in elderly COVID-19 patients is higher than that in young and middle-aged patients. CRP level has a good predictive value for the possibility of severe events in elderly COVID-19 patients.
