Influence of directed restrictive fluid management strategy on patients with serious burns complicated by severe inhalation injury

Objective: To explore the influence of directed restrictive fluid management strategy (RFMS) on patients with serious burns complicated by severe inhalation injury. Methods: Sixteen patients with serious burns complicated by severe inhalation injury hospitalized in our department from December 2014 to December 2017, meeting the inclusion criteria and treated with RFMS, were enrolled in directed treatment group. Thirty-four patients with serious burns complicated by severe inhalation injury hospitalized in our department from December 2012 to December 2017, meeting the inclusion criteria and without RFMS, were enrolled in routine treatment group. Medical records of patients in 2 groups were retrospectively analyzed. Within post injury day 2, mean arterial pressure (MAP), central venous pressure (CVP), extravascular lung water index (ELWI), global end-diastolic volume index, and pulmonary vascular permeability index of patients in directed treatment group were monitored by pulse contour cardiac output monitoring technology, while MAP and CVP of patients in routine treatment group were monitored by routine method. On post injury day 3 to 7, patients in 2 groups were treated with routine fluid supplement therapy of our Department to maintain hemodynamic stability, and patients in directed treatment group were treated according to RFMS directed with goal of ELWI≤7 mL·kg(-1)·m(-2). On post injury day 3 to 7, total fluid intake, total fluid output, and total fluid difference between fluid intake and output within 24 h, value of blood lactic acid, and oxygenation index of patients in 2 groups were recorded. Occurrence of acute respiratory distress syndrome (ARDS) on post injury day 3 to 7 and 8 to 28, mechanical ventilation time within post injury day 28, and occurrence of death of patients in 2 groups were counted. Data were processed with chi-square test, t test, and analysis of variance for repeated measurement. Results: The total fluid intakes within 24 h of patients in directed treatment group were close to those in routine treatment group on post injury day 3, 4, 5, 6, 7 (t=-0.835, -1.618, -2.463, -1.244, -2.552, P>0.05). The total fluid outputs and total fluid differences between fluid intake and output within 24 h of patients in 2 groups on post injury day 3 were close (t=0.931, -2.274, P>0.05). The total fluid outputs within 24 h of patients in directed treatment group were significantly higher than those in routine treatment group on post injury day 4, 5, 6, 7 (t=2.645, 2.352, 1.847, 1.152, P<0.05). The total fluid differences between fluid intake and output within 24 h of patients in directed treatment group were (2 928±768), (2 028±1 001), (2 186±815), and (2 071±963) mL, significantly lower than (4 455±960), (3 434±819), (3 233±1 022), and (3 453±829) mL in routine treatment group (t=-4.331, -3.882, -3.211, -4.024, P<0.05). The values of blood lactic acid of patients in directed treatment group and routine treatment group on post injury day 3, 4, 5, 6, 7 were close (t=0.847, 1.221, 0.994, 1.873, 1.948, P>0.05). The oxygenation indexes of patients in directed treatment group on post injury day 3 and 4 were (298±78) and (324±85) mmHg (1 mmHg=0.133 kPa ), which were close to (270±110) and (291±90) mmHg in routine treatment group (t=-1.574, 2.011, P>0.05). The oxygenation indexes of patients in directed treatment group on post injury day 5, 6, 7 were (372±88), (369±65), and (377±39) mmHg, significantly higher than (302±103), (313±89), and (336±78) mmHg in routine treatment group (t=3.657, 3.223, 2.441, P<0.05). On post injury day 3, 4, 5, 6, 7, patients with ARDS in directed treatment group were less than those in routine treatment group, but with no significantly statistical difference between the 2 groups (χ(2)=0.105, P>0.05). On post injury day 8 to 28, patients with ARDS in directed treatment group were significantly less than those in routine treatment group (χ(2)=0.827, P<0.05). The mechanical ventilation time within post injury day 28 of patients in directed treatment group was apparently shorter than that in routine treatment group (t=-2.895, P<0.05). Death of patients in directed treatment group within post injury day 28 was less than that in routine treatment group, but with no significantly statistical difference between the 2 groups (χ(2)=0.002, P>0.05). Conclusions: Under the circumstance of hemodynamics stability, RFMS directed with goal of ELWI≤7 mL·kg(-1)·m(-2) on post injury day 3 to 7 is an useful strategy, which can reduce occurrence rate of ADRS and shorten mechanical ventilation time of patients with serious burns complicated by severe inhalation injury at late stage of burns.

Effect of continuous plasma filtration adsorption on treatment of severely burned patients with sepsis

Objective: To investigate effect of continuous plasma filtration adsorption on treatment of severely burned patients with sepsis. Methods: In January 2014 to September 2017, 86 severely burned patients with sepsis, conforming to the study criteria, were admitted to our hospital and divided into into routine treatment group and continuous plasma filtration group according to the random number table method, with 43 patients in each group. Patients in routine treatment group were treated with routine treatment after admission. Patients in continuous plasma filtration group were treated with blood filter, blood purification machine, and plasma separator for continuous plasma filtration adsorption on the basis of the routine treatment group on the second day after admission. The course of treatment in the 2 groups was 7 d. The total effective treatment rate, changes of leukocyte count (WBC), usea nitrogen, serum creatinine, neutrophile CD64, procalcitonin, and C reactive protein (CRP) before and after treatment, and mortality on 28 days after treatment of patients in 2 groups were analyzed and compared. Results: (1) The total effective treatment rate of patients in continuous plasma filtration group was 88.37% (38/43), which was significantly higher than that of the routine treatment group [65.12% (28/43), χ(2)=6.515, P=0.018]. (2) After treatment, WBC, urea nitrogen, serum creatinine, neutrophils CD64, procalcitonin, and CRP of patients in continuous plasma filtration group were significantly lower those in routine treatment group (t=6.305, 4.420, 18.537, 13.435, 12.975, 14.234, P<0.05). WBC, urea nitrogen, serum creatinine, neutrophile CD64, procalcitonin, and CRP of patients in 2 groups after treatment were significantly lower than those before treatment (t=9.459, 9.130, 25.438, 35.467, 23.471, 23.601, 3.802, 5.662, 12.067, 25.694, 20.720, 12.437, P<0.05). (3) On 28 days after treatment, mortality of patients in continuous plasma filtration group was 6.98% (3/43), which was significantly lower than that in routine treatment group [25.58% (11/43)], χ(2)=5.460, P=0.023. Conclusions: Continuous plasma filtration adsorption is effective in treating severely burned patients with sepsis, which can alleviate inflammatory reaction mediated by inflammatory cytokine with good prognosis.

Effect of IFN-α on Cytokines in Serum of Patients with Chronic Myeloid Leukemia

To investigate the effect of IFN-α on cytokines in serum of patients with chronic myeloid leukemia(CML). Fifty patients with CML from March 2012 to December 2015 in our hospital were randomly divided into routine treatment group (n=25) and combined treatment group (n=25), 30 healthy persons were selected as control (control group). The CML patients in routine treatment group were given orally hydroxyurea, the CML patients in combined treatment group were treated with recombinant human interferon α2b injection based on routine treatment (hydroxyurea plus IFN-α group). The levels of ALP, IL-6, PGE-2, MMP-2, and bFGF in serum were detected by ELISA. The cytogenetic, molecular and hematologic responses of patients in routine treatment group and combined treatment group, including patients in chronic and accelerated blastic phases were compared after 6 weeks of treatment. The servum levels of ALP, IL-6, PGE-2, MMP-2 and bFGF in CML patients with chronic and accelerated blastic phases all were higher than those in control group(P<0.05). The levels of MMP-2 and bFGF in CML patients with chronic phase were highr than those of CML patients with accelerated blastic phase (P<0.05), the levels of ALP, PGE-2 and IL-6 of patients with chronic phase were significantly lower than those of patients in accelerated blastic phase (P<0.05). The ALP, IL-6, PGE-2, MMP-2 and bFGF levels in combined treatment group were significantly lower than those in the routine treatment group after 2 weeks and 6 weeks of treatment(P<0.05); After the end of treatment, the CHR of routine treatment group was 56%, which was lower than that of combined treatment group 84%(χ2=18.667, P<0.001); the CCyR of routine treatment group was 32% which was significantly higher than 12% in combined treatment group(χ2=11.655, P<0.001); the CMR of routine treatment group was 12% that was significantly higher than 4% in combined treatment group (χ2=4.347, P=0.037). The median survival time of routine treatment group was significantly shorter than that of the combined treatment group, but there was no significant difference during follow-up (P>0.05). IFN-α can alleviate the symptoms of patients with CML and inhibit the process of disease with CML patients, effectively inhibit the expression of disease-related cytokines.

Clinical value of monitoring subdural intracraniai pressure in post-operative patients with severe brain injury

Objective To investigate the value of subdural intracranial pressure (ICP) monito-ring in post-operative patients with severe brain injury. Methods A total of 100 patients with severe brain injury treated with craniotomy were randomly divided into ICP monitoring group (n=50) and rou-tine treatment group (n = 50). In ICP monitoring group, the treatment methods were adjusted according to the changes of ICP, whereas the patients in routine treatment group underwent general treatment ac-cording to standard neurosurgical protocol. Results Patients in ICP monitoring group received mannitol for eight days, with the average dosage of 950 g. Marmitol was administered to patients in routine treat-ment group for 12 days, with average dosage of 1 450 g. There was statistical difference in aspects of time duration and mannitol dosage between two groups (P 0.05). The post-operative initial ICP level was positively correlated with mortality rate (P <0.01). All patients were followed up for three months post-operatively. In ICP monitoring group, 27 patients (26%) obtained good prognosis without any disability (54%), 13 were under mild disability, two (4%) under severe disability, three (6%) under vegeta-tive state and five (10%) died . In the routine treatment group, 17 patients (34%) were with good prognosis without any disability , six (12%) with mild disability , six (12%) with severe disability, eight (16%) under vegetative state and 13 (26%) died. The ICP monitoring group had better prognosis than the routine treatment group(P < 0.05). Conclusion Continuous ICP monitoring postoperatively in severe brain injury patients is valuable in reducing mortality, complication and improving the prognosis.

Effects of gastrodin injection on blood pressure and vasoactive substances in treatment of old patients with refractory hypertension: a randomized controlled trial

To examine and determine the contents of endothelin (ET) and nitric oxide (NO) in plasma, and to observe the effects of gastrodin injection on blood pressure, ET and NO levels in old patients with refractory hypertension. A total of 63 old patients with refractory hypertension, 30 patients with common hypertension and 30 healthy people were included. The contents of ET and NO in plasma of patients in different groups and healthy people were examined and analyzed. The old patients with refractory hypertension were randomly divided into two groups: gastrodin-treated and routine treatment groups. Besides conventional hypotensive drugs, intravenous drip infusion of 1 000 mg gastrodin was administered to the patients in gastrodin-treated group for two courses (4 weeks), while the patients in routine treatment group were treated only with conventional hypotensive drugs. The changes of blood pressure, ET and NO levels before and after treatment in different groups were measured. The plasma level of ET in refractory hypertension group was higher than that in common hypertension group (t=3.27, P=0.008), while the level of NO was lower (t=-3.81, P=0.002). The systolic pressure and pulse pressure difference in gastrodin-treated group were decreased significantly after one course of treatment (t=1.85, P=0.03; t=1.74, P=0.04). The level of ET in gastrodin-treated group decreased gradually after treatment, but there were no significant difference between before treatment and two courses of treatment, while the level of NO in gastrodin-treated group was increased after treatment (t=-2.70; P=0.04). Gastrodin injection is beneficial to old patients with refractory hypertension, and can improve the balance of ET and NO levels in plasma.
