CONCLUSIONS CRI is related to the indwelling time, fungi are the major pathogens. It is important to prevent CRI through careful nursing. We must pull out the catheters if recessary and antibiotics should be used reasonablly.

Objective To observe the effect of Shenfu injection on fluid intake volume of resuscitation therapy for patients with septic shock. Methods The clinic data of 36 patients with septic shock admitted to Department of Critical Care Medicine of the Affiliated Hospital of Hangzhou Normal University from June 2010 to June 2013 were retrospectively analyzed. All the patients were treated with western conventional medicine. Twenty cases treated with western medicine combined with Shenfu injection (intravenous drip 100 mL once daily, half of a month was a therapeutic course) were defined as Shenfu group; the rest 16 cases treated with western medicine only were assigned as control group. The following data after treatment for 6, 24, and 72 hours in the two groups were compared:liquid intake and urine volumes, system vascular resistance index (SVRI), mean arterial pressure (MAP), cardiac index (CI), and case fatality rate in 28 days. Results There were no significant differences in the liquid intake volume in 6 hours after treatment (mL:3 101±219 vs. 3 329±295, P>0.05), the urine volumes in 6, 24 and 72 hours after treatment (mL, 6 hours:701±229 vs. 651±292, 24 hours:1 870±566 vs. 1 697±618, 72 hours:7 396±2 546 vs. 5 987±2 497), and the levels of SVRI in 24 hours after treatment between Shenfu group and control group (kPa·s·L-1·m-2:802±158 vs. 741±106, all P>0.05). The total liquid intake volumes (mL) in 24 hours and 72 hours after treatment in Shenfu group were significantly less than those in the control group (24 hours:4 544±425 vs. 4 996±396, 72 hours:10 985±891 vs. 11 612±807, both P<0.05). The SVRI, MAP, and CI in 72 hours of Shenfu group were significantly higher than those of control group [SVRI (kPa·s·L-1·m-2): 1 361±182 vs. 1 163±183, MAP (mmHg, 1 mmHg = 0.133 kPa): 76.2±6.1 vs. 71.8±6.3, CI (mL·s-1·m-2):76.2±7.5 vs. 70.8±7.2, all P<0.05], and the 28-day mortality rate in Shenfu group was significantly lower than that of control group [25.0%(5/20) vs. 62.5%(10/16), P<0.05]. Conclusion The application of Shenfu injection was favorable to the reduction of liquid intake volume in 72 hours after treatment that may be beneficial to the fluid limitation management in the course of treatment for septic shock.

OBJECTIVETo investigate the distribution and the antimicrobial resistance of the bacteria, mycoplasma and Chlamydia trachomatis isolated from the prostatic secretion of infertile men with chronic prostatitis, and to provide clinicians with grounds for choosing antibiotic agents.

METHODSThe bacteria obtained were isolated and identified, the Chlamydia trachomatis was detected by FLO-PCR, and the results were analysed statistically.

RESULTSIn 1 186 specimens of EPS, the total positive rate of isolates was 51.7%. Among them, there were 364 strains of gram-positive coccus, 20 gram-negative bacillus, 5 other strains and 157 mycoplasma, including 116 Ureaplasma urealyticum and 41 Mycoplasma hominis, and 67 Chlamydia trachomatis DNA. As for the isolated staphylococci, their antimicrobial resistance was the lowest against vancomycin (0.0%), but the highest against penicillins (76.9%-100%); for the Streptococcus agalactiae, it was the highest against erythromycin and clindamycin (100%), and the lowest against beta-lactams, aminoglycosides, trimethoprim + sulfamethoxazole, rifampin and vancomycin (0.0%); for the Ureaplasma urealyticum, it was the highest against ciprofloxacin (59.5%), and the lowest against josamycin, tetracycline and fosfomycin (1.7%); for the Mycoplasma hominis, it was the highest against erythromycin (100%), and the lowest against doxycycline and fosfomycin (0.0%).

CONCLUSIONBacteria, mycoplasma and Chlamydia trachomatis are the possible etiological factors of male infertility. Isolated bacterial strains differ greatly in their resistance against different antibiotics.

Objective: To investigate the effect of global end-diastolic volume index (GEDI)-guided fluid resuscitation on the prognosis of patients with chronic heart failure and septic shock. Methods: This study was a prospective randomized controlled study. Consecutive eligible patients were divided into 2 groups according to the random number table method: control group (n=21) and experimental group (n=20). On the basis of routine treatment, patients in the control group received early goal-directed therapy until the central venous pressure (CVP) reaching 8-12 mmHg (1 mmHg=0.133 kPa), mean arterial pressure reaching over 65 mmHg, urine volume reaching over 0.5 ml·kg^-1·h^-1, and central venous oxygen saturation reaching more than 70%. On the basis of routine treatment, patients in the experimental group were monitored continuously on cardiac output with pulse indication and fluid resuscitation guided by volume index GEDI. The GEDI should be maintained on the range of 680-800 ml/m². The remaining resuscitation goals were the same as control group. General clinical data of the two groups were collected at admission. Negative fluid balance onset time, duration of mechanical ventilation, ICU mortality and 28-day mortality were compared between the two groups. The outcomes were recorded as listed: start time of negative fluid balance, duration of mechanical ventilation, mortality in ICU and 28-day mortality. Results: There was no significant difference in age, sex, weight, APACHE Ⅱ score, SOFA score and NYHA functional class score between the two groups (all P>0.05). The negative liquid balance onset time in the control group was 3.5 (2.5, 4.0) days, which was significantly longer than that in the experimental group (2.6 (2.0, 3.0) days,U=115.0, P=0.012). The duration of mechanical ventilation was 355 (118, 552) hours in the control group, which was significantly longer than that in the experimental group (132 (36.75, 233.3) hours, U=130, P=0.038). The ICU mortality was 38.1% (8/21) in the control group, tended to be higher than that in the experimental group (20.0%(4/20), χ²=1.620, P=0.203). The 28-day mortality was 42.9% (9/21) in the control group, similar as in the experimental group (25.0%(5/20), χ²=1.482,P=0.477). Conclusion Fluid resuscitation guided by volume index (GEDI) may improve the prognosis of patients with chronic heart failure complicated with septic shock.

Objective:To explore the guiding effect of peripheral perfusion index (PI) on fluid resuscitation in patients with septic shock.Methods:Sixty-five patients with septic shock who were diagnosed according to relevant criteria of septic shock and admitted to the department of critical care medicine of the Affiliated Hospital of Hangzhou Normal University from September 2017 to December 2020 were included. Patients were divided into the conventional treatment group (30 cases) and PI guidance group (35 cases) by random number method. Both groups of patients were treated with the bundle according to clinical guidelines. Sputum, urine and blood were collected for pathogenic microorganism culture before the application of antibiotics, and vasoactive drugs were given. Both groups need to achieve all the following resuscitation goals within 6 hours: urine output > 0.5 mL·kg -1·h -1, mean arterial pressure (MAP) ≥ 65 mmHg (1 mmHg ≈ 0.133 kPa), central venous pressure (CVP) was 8-12 mmHg, and central venous oxygen saturation (ScvO 2) ≥ 0.70. There was no further resuscitation in the conventional treatment group after the goals were achieved. In addition to these four goals, the PI guidance group was expected to achieve PI≥ 1.4. Heart rate (HR), CVP, MAP, ScvO 2, blood lactic acid (Lac), the time of fluid negative balance, intensive care unit (ICU) mortality and 28-day mortality between the two groups were compared before and after 6 hours of fluid resuscitation. Results:Before fluid resuscitation, there were no statistically significant differences in all indicators between two groups. After 6 hours fluid resuscitation, the four treatment goals in PI guidance group were slightly lower than those of the conventional treatment group [HR (times/min): 96.5±12.1 vs. 97.7±7.9, MAP (mmHg): 83.2±6.2 vs. 82.1±7.5, ScvO 2: 0.661±0.077 vs. 0.649±0.051, CVP (mmHg): 10.8±2.7 vs. 10.4±2.1], there were no statistically significant differences between the two groups (all P > 0.05); the Lac level of the PI guidance group after resuscitation was lower than that of the conventional treatment group, and the difference was statistically significant (mmol/L: 4.8±1.3 vs. 5.9±1.4, P < 0.05); the duration of fluid negative balance in the PI guidance group was earlier than that in the conventional treatment group [days: 3.0 (2.0, 3.0) vs. 3.5 (3.0, 4.0), P < 0.05]. The ICU mortality and 28-day mortality in the PI guidance group were lower than those in the conventional treatment group [ICU mortality rate: 37.1% (13/35) vs. 50.0% (15/30), 28-day mortality rate: 57.1% (20/35) vs. 60.0% (18/30)], but the differences were not statistically significant (both P > 0.05). Conclusions:The peripheral PI can be used as an important indicator of fluid resuscitation in patients with septic shock. PI guiding fluid resuscitation in patients with septic shock can reduce Lac levels, shorten the duration of fluid negative balance and reduce the risk of fluid overload.
