ABSTRACT
Objective @#To investigate the influencing factors of vascular crisis after oral and maxillofacial tumor free tissue flap transplantation. @*Methods @# A retrospective analysis was performed on all patients who underwent free tissue flap transplantation and developed vascular crisis in the surgical ward of head and neck cancer in a grade A specialized hospital. Forty-six possible influencing factors were collected using 1:1 matching according to surgeons, operation time, sex and age of patients from patients without vascular crisis from 2015-2020 in this ward during the same period. SPSS 26.0 statistical software was used for univariate and multivariate logistic regression analyses of the data.@*Results @#A total of 158 patients were enrolled, including 79 in the crisis group and 79 in the pairing group. Univariate analysis was performed for each variable. Paired logistic regression analysis showed that only postoperative blood potassium (P = 0.048, OR = 3.118, 95% CI: 1.008-9.641) and preoperative and postoperative red blood cell count differences (P = 0.004, OR = 4.53, 95% CI: 1.609-12.750) were statistically significant.@*Conclusion @#High blood potassium levels and red blood cell count differences before and after surgery were risk factors for vascular crisis.
ABSTRACT
To explore the mechanism of obstructive sleep apnea(OSA) by assessing the association between human TWIK-related acid-sensitive K channel-1(TASK-1) gene and OSA. A total of 164 patients with severe OSA and 171 patients without OSA were recruited from the Hypertension Center of People's Hospital of Xinjiang Uygur Autonomous Region,China,from April to December 2016.Two single nucleotide polymorphisms(rs1275988 and rs2586886) in the TASK-1 gene were selected and genotyped using a Kompetitive Allele Specific PCR genotyping system. In patients with blood potassium 3.95 mmol/L in patients with TASK-1 GG genotype may be conducive to reducing the incidence of severe OSA.

ABSTRACT
Objective: To study the changes of blood transfusion and blood potassium concentration and the occurrence of hyperkalemia after transfusion factors influence. Methods: In our hospital from 2010 April to select the diagnosis and treatment of -2012 in April 132 cases of non crush injury patients, these patients were randomly divided into two groups, the control group without blood transfusion therapy group, the observation group for massive transfusion treatment group, changes of serum potassium were compared between the two groups before and after transfusion, and to analyze the related effect factors. Results:The serum potassium levels showed no significant difference between the two groups of patients before and after blood transfusion, operation process, but the postoperative within 12h, observation of blood potassium level group were significantly higher than that in control group, the difference is significant, with statistical significance (t=1.562, P<0.05), in addition to 12h after operation, blood potassium levels between the two groups no significant difference. Conclusion: The clinical blood transfusion is not the main cause of hyperkalemia in patients with, but there are still some patients in massive transfusion potassium increased, therefore, in the process of transfusion, or to close monitoring and observation of the serum potassium level, but also to pay attention to changes in renal function, has ruled out the elevation of serum potassium results in impaired renal function because, in order to reduce the incidence of complications.
ABSTRACT
BACKGROUND: The purpose of this study was to assess the effect of rocuronium pretreatment on the succinylcholine induced biochemical changes and fasciculations, myalgia and to compare it with vecuronium pretreatment. METHODS: We have studied 60 patients undergoing minor elective surgery, in a prospective double blinded method. Three groups of 20 patients each were pretreated with saline 0.01 ml/kg (group C), rocuronium 0.05 mg/kg (group R), or vecuronium 0.007 mg/kg (group V). Three minutes after the pretreatment, 1.5 mg/kg succinylcholine was injected. Serum potassium five minutes after succinylcholine and creatine kinase 24 hr after operation were measured. Fasciculations and postoperative myalgia at 24 and 48 h were evaluated. RESULTS: The increase in creatine kinase and incidence of fasciculations were lowest in the rocuronium group (33 IU/L; 15%) and followed by vecuronium group (58 IU/L; 50%) and highest in the control group (101 IU/L; 100%). The increase in serum potassium concentration (0.3 mEq/L) was not attenuated by any regimen. The incidence of postoperative myalgia on day 1 and day 2 was lower in the rocuronium (40%, 30%) and the vecuronium (50%; 35%) group than control group (85%; 75%). CONCLUSIONS: Rocuronium pretreatment is more effective in reducing creatine kinase rise and fasciculations after succinylcholine than vecuronium. However rocuronium and vecuronium are also effective in preventing postoperative myalgia.
