ABSTRACT
Objective:To master with structure and function of ForceTriad energy platform, improve the effect of daily maintenance, use the energy platform safety and accurately.Methods:Specific methods involved in connection to the host and device, circuit plate electrode placed, unipolar and bipolar operation points and attention patient position, the common failures and troubleshooting methods.Results: To prevent electric shock and prevent burn patients are fundamental, the key is to connect closely and good contact, maintenance and troubleshooting is the guarantee. Conclusion:Safely use of energy platform correctly, cleaning maintenance equipment in a timely manner, accurate troubleshooting, to give full play to the advantages of energy platform, improve the operation efficiency and effectiveness.
ABSTRACT
Objective To investigate the effect of sodium nitroprusside sustained release on cognitive function, S-100βprotein and VILIP-1 in pituitary tumor surgery patients.Methods 156 cases of pituitary tumor patients were selected and divided into two groups according to random number table method,78 patients in each group.All patients underwent general anesthesia induction,the experimental group treated with 0.5~6 μg ( kg· min) infusion of sodium nitroprusside induced hypotension by micro pump at the beginning of operation.MMSE was used to determine the cognitive function of 2 groups of patients 1 day before operation and 2 days after operation,S-100βand VILIP-1 content were determined by ELISA before anesthesia,after surgery,and 0,12,24,48 h after operation.Results There was no statistical significance between the 2 groups in the incidence of postoperative cognitive dysfunction.Compared with control group, the operation time, bleeding volume and the recovery time of the experiment group were lower(P<0.05).S-100βprotein and VILIP-1 showed increased at first and then decreased at the peak of 24h;compared with the normal group, the levels of S-100βprotein and VILIP-1 of the cognitive impairment were higher ( P <0.05 ).Compared with the control group, the levels of S-100βprotein and VILIP-1 of the experiment group were lower(P <0.05).Conclusion Sodium nitroprusside sustained release controlled hypotension can reduce the level of cognitive disorder, patients of S-100βprotein and visinin-like protein 1 and has certain directive significance to the clinical.
